EXECUTIVE SUMMARY

Tragelaphus spekii (Speke, 1863) (Sitatunga) is a highly valued trophy antelope and one of the

key flagship species of economic value for promoting tourism in the previously non attractive sites,

especially the wetlands across Uganda. The antelope is dependent on wetland habitat and any

developments and degradations which negatively affects wetland status, negatively affect the

survival of the species. There is generally very scanty information on sitatunga population and

distribution in Uganda. This study commissioned by UWA on the population, distribution and

conservation status of sitatunga in selected wetlands in Uganda was aimed at providing

information on the (i) occurrence, distribution and relative abundance of sitatunga, (ii) evaluating

threats to the conservation of sitatunga and wetlands, (iii) assessing local community knowledge

on sitatunga (iv) developing a framework for monitoring the abundance, distribution patterns of

sitatunga and wetland resource use, (v) developing guidelines for allocation of national sitatunga

sport hunting quota and (vi) to undertake a Non Detrimental Finding (NDF) of sitatunga in Uganda.

The study was undertaken in six concession sites; (i) Lake Opeta and Bisina wetland system in

Karamoja and Teso regions, (ii) Lugogo wetland system in the districts of Nakaseke, Luwero and

Nakasongola, (iii) Mayanja wetland system in the districts of Nakaseke, Kiboga and Kyankwanzi,

(iv) Kafu River basin in Masindi, and Nakasongola, (v) Katonga wetlands along River Katonga in

Katonga Wildlife reserve and (vi) Ssese islands in Kalangala districts. The study adopted a

modified sampling approach developed for studying spatial and temporal variation in the

abundance of songbirds which was used by Beudels-Jamar et al. (1997) at Parc national de

Akagera in Rwanda to estimate population of sitatunga. Recee walks, and community interviews

were also used to provide distribution, relative abundance and habitat status. Community surveys

were conducted to gain information on their understanding of and factors affecting the survival of

sitatunga. The findings of the study indicate that sitatunga still occurs in viable populations in the

study sites. The study also demonstrated the importance of sustainable use of wetlands ecosystem

as critical for conservation of sitatunga in the country. The main human threats that negatively

impacts on conservation of sitatunga included habitat loss due to human extractive activities,

ranging from increased need for wetland for farming due to climate change impacts, expansion of

agricultural land in wetlands to produce food to feed the increasing human populations. Areas with

intensive human activity held low abundance of sitatunga population. For these reasons, it was

recommended to implement conservation actions and activities focusing on;

The findings of this study indicate that sitatunga still occurs in relatively viable populations in the

study sites. The study also demonstrated the importance of sustainable use of wetlands as critical

for conservation of sitatunga in the country. The main threat that significantly impacts on

conservation of sitatunga include habitat loss due to human activities ranging from need for land

for farming due to climate change impacts, need to feed increasing human populations and

urbanization among others. Five categories of human threats were recorded from this study

and the intensity of each of these categories also varied in different wetland sites. The

abundance and distribution of sitatunga varied between habitats as a result of the presence of

human threat indicators as shown in this study. Sitatunga is an antelope species which is dependent

on wetland habitat and any development which negatively affect wetland status negatively affect

Page 9: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

the survival of the species. Areas with intensive human activity registered low abundance of

sitatunga. This calls for urgent actions to mitigate human induced wetland habitats degradation

which will not only the help in securing sitatunga conservation but also other wildlife and

ecosystem services that accrues from the conservation of the wetlands. To promote sustainable

future for sitatunga in the wetland ecosystems the following actions are recommended:

(i) Take landscape based approach to conservation actions and activities, recognizing the

three major habitat functions (a) the wetland landscape which provides habitat to wider

ecosystem services to the community, (b) being habitats for sitatunga and other wildlife

species, and (c) humans use of wetland habitat for extractive and consumptive

resources to advance wetland management objectives.

(ii) Develop sensitization and awareness campaign programmes that might improve

networking and collaboration between stakeholders and possibly attract their

interest in the protection of the wealth of biodiversity in the wetland ecosystem. In

this regard, sensitization and awareness campaigns addressing the wetland

management policies, risks and benefits that may accrue from successful participation

and conservation are recommended.

(iii) Develop integrated approach to conservation of wetland ecosystem through; Investing

in alternative livelihoods opportunities based on sustainable use of wildlife resources

and its habits such as bee keeping, monitored resources extraction. This would be

alongside sport hunting or ranching of wildlife for meat to provide financial incentives

for the local community to maintain wildlife in these corridor areas. The adjacent

communities in these wetland systems need to be sensitized on how to sustainably use

resources in their area while conserving them.

(iv) Continuous monitoring of sitatunga population and other wildlife species in wetland

for remedial conservation action is proposed. In this regard, both scientific and

integrated (including stakeholders) long-term ecological monitoring programs are

suggested. This can be done through establishing a wildlife population and habitat

monitoring system with incorporation of community conservation initiative

programmes in wetland. Scientific monitoring of sitatunga and large mammal

population on the transects within wetlands that were surveyed during this study in the

study sites. Additional monitoring is proposed especially in Ssese islands which

contains endemic island sitatunga subspecies is recommended. Incorporate community

in the monitoring of sitatunga and wetland health for wider benefit such as ecosystem

service and conservation of sitatunga.

(v) Due to the increasing human pressure on wetland there is need to demarcate wetland

boundaries to reduce encroachments. It is also important to ensuring connectivity

between different wetland systems through creating corridors to links two or more

larger wetlands habitats is vital to facilitate dispersal or allow undisturbed movement

of sitatunga within different populations/sites to avoid potential challenges of

inbreeding and promote healthy and viable populations.

Page 10: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

(vi) Strengthen institutions responsible for wetland management at local government levels.

There is need to sensitize, train and strengthen local government at district and lower

levels (environment committee) to management the wetlands sustainably.

(vii) Initiate collaborative management of wildlife on private/public land for management

of wetland habitats. This is consistent with the Uganda Wildlife Act (2000) and the

Local Government Act (1997) and other laws and guidelines that may supplement

implementation of such imitative.

(viii) Develop Conservation Actions and species management plan for Sitatunga. This will

help in regulating and management of harvest and Trade in the species by the local

community and general public.

(ix) Development of enabling policy framework for wetland management, including:

a. Design and implement Ramsar sites and Framework wetland management plans.

b. Design and implementation of Ramsar site wetland research, eco-tourism and

education centers.

c. Design and implement District wetland action plans, with biodiversity and carbon

sink potential.

d. Promote wetlands law enforcement and governance.

e. Restore, regenerate, restock and gazette degraded wetlands in urban areas so as to

conserve biodiversity and promote increased ecosystem serves provision.

(xii) Create an Island National Park in Lake Victoria Islands with Island Sitatunga

(T.s.sylvestris) as a Flagship Species for promoting Tourism in the Ssese Island. It has been

identified as potential endemic in Africa due to restricted occurrence in Ssese Island.

(xiii) To institute byelaws on sustainable use of wetland and to ban burning of the swamps

/wetlands which are the habitats for sitatunga.

1.0`INTRODUCTION

1.1Background

Sitatunga (Tragelaphus spekii) is a spiral horned antelope endemic to sub-Saharan Africa. It

belongs to the tribe Tragelaphini, order artiodactyla (even-toed), family bovidae and the genus

Tragelaphus. The genus also includes the Giant Eland (Tragelaphus derbianus), Common Eland

(Tragelaphus oryx), Nyala (Tragelaphus angasi), Bushbuck (Tragelaphus scriptus), Mountain

Nyala (Tragelaphus buxtoni), Lesser Kudu (Tragelaphus imberbis) and Greater Kudu

(Tragelaphus strepsiceros). Its Afrikaans name “water-kudu” refers to the animal’s aquatic and

thus amphibious behavior (meaning it can live on both land and water). It is mainly confined to

swampy and marshy habitats (Dudgeon, 2008). As an adaptation to living in swampy or marshy

habitats it has elongated, narrow and wide-splayed hooves (Alden et al., 1996) and the skin coat

is shaggy, oily and a film of oil tends to float when the animal immerses itself in water (Alden et

al., 1996; Kingdon, 1982). Sitatunga mainly inhabits tall and dense vegetation of perennial as well

as seasonal swamps, marshy clearings in forests, riparian thickets and mangrove swamps

(Magliocca et al., 2002). Sitatunga mainly moves along clearly marked tracks in their swampy

habitat, often leading to reed beds (Amin et al., 2016). The tracks, may reach up to 7 m (23 ft)

wide, leading to feeding grounds located in the nearby riverine forests (Thome, 2010).Sitatunga

holds small home ranges near water bodies (Noss et al., 2012). In savannas, they are typically

found in stands of papyrus and reeds (Phragmites species and Echinochloa pyramidalis). They

share their habitat with the Nile lechwe in the Sudd swamps in Southern Sudan and with the

southern lechwe in Angola, Botswana and Zambia (IUCNSSC, 2008).In Uganda Sitatunga has

been recorded to occur in Murchison Falls National Park (NP) (Andama and Ocen, 2002), Kibale

NP, Lake Mburo N.P and Katonga Wildlife Reserve (WR) (Wilson, 1995), Semliki NP, Bwindi

Impenetrable N.P, Ajai WR and Pian Upe WR. However, much of the ranges where Sitatunga

occurs are outside the protected areas in the private land. In general there is little knowledge on

population and distribution of Sitatunga in Uganda and yet, these animals face constant threats due

to hunting and habitat destruction by the neighboring communities. Rossi (1999) reported that

sitatunga occurs quite widely in swamps associated with Uganda's extensive lake and river

systems. Among all wildlife taxa, sitatunga are the most prone to local extirpation as they

are specifically adapted to wetland habitats which are vulnerable to human modification. Sitatunga

just like other mammal species contribute to ecosystem functioning (Wunderle, 1997), however,

the population and suitable habitats for their survival are reportedly declining across Africa

because of human activities, including direct exploitation and habitat alteration (Craigie et al.,

Page 12: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

2

2010, Morrison et al., 2007). In order to avoid extermination there is an urgent need to secure and

maintain sites containing reasonable populations and assemblages of Sitatunga. For effective

management of wildlife populations, there is need to provide accurate knowledge of population

densities, diversity, distribution and their habitat preferences (Cassey, 1999) and constantly

monitor populations (Varman & Sukumar, 1995). To promote sustainable conservation of

Sitatunga there is thus need for investigation of underlining knowledge in human societies, their

activities and the effects of their activities on sitatunga habitat. This knowledge is used to develop

favorable policies for sustainable management of sitatunga populations. Specifically, conservation

strategies laid down under wetland policy are currently facing implementation challenges due

to the lack of adequate ecological information on which effective conservation and

management strategies and policies could be based (Nature Uganda 2009). This study established

the potential challenges facing sitatunga conservation and other wetland wildlife species in relation

to different human activities and how the species is likely to respond to different habitats and

habitat alterations caused by humans.

1.2. Justification of the study

Sitatunga is one of the Africa’s least known antelopes (Owen, 1983). However, reliable estimates

of the size of natural populations of Sitatunga are important for development of effective

strategies for management and conservation of the species by Uganda Wildlife Authority (UWA)

that is mandated with sustainable utilization of wildlife resources in Uganda. The interest on

sitatunga study started when the species was included in the sport hunting list by UWA in 2008.

Undetaking estimates of the sitatunga population in hunting concessions areas across Uganda is

essential to ensure that sport hunting is managed sustainably (Camille & Boyce, 2016). To improve

the conservation of sitatunga in Uganda, primary information is needed on its occurrence,

distribution, abundance, population size, habitat requirements and anthropogenic factors such as

hunting and human impacts on its habitats. Currently there is generally very scanty information on

the Sitatunga population and distribution status within Uganda and very little elsewhere in Africa

(e.g. Owen, 1970; Williamson, 1986). Habitat specialization of Sitatunga suggests that it may have

great significance on the ecology of plants and other living organisms occurring in the same habitat

(Ndawula et al., 2011). In 2010 UWA authorized trophy hunting for sitatunga (Thome, 2010) but

this was not based on distribution and population status information. Although sustainable sport

hunting can provide the crucial funds for conservation, especially in areas rarely visited by tourists,

this requires knowledge about populations, habitat and threats. The proposed quota by UWA for

Sitatunga harvest was based on adaptive management approach, which is a widely accepted and

Page 13: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

3

used (Bunnefed et al., 2015.; Muposhi et al., 2016& Packer et al., 2011) across the world

especially where data on animal populations is scanty or unreliable. It is thus very prudent to

propose hunting quota based on reliable population estimates. Information about sitatunga

population density and distribution will not only improve local management, but also add to the

body of knowledge about sitatunga that can aid in conservation of the species across its range.

Sitatunga subspecies Tragelaphus spekii sylvestris (island Sitatunga) is globally categorized as

Not Evaluated (NE) due to limited scientific information about the sub species. The subspecies is

particularly restricted in distribution within Ssese islands (WCS et al., 2016). National status

assessment categorized it as CR (critically endangered) B1ab (v) because it is endemic to Ssese

islands (WCS et al., (2016)) with restricted distribution. The East African Sitatunga (Tragelaphus

spekii spekii) is considered widespread within Uganda and is categorized globally as LC (LC least

concern) but nationally VU (vulnerable) B1b (i) c (i) due to the challenges of habitat loss (WCS

et al., 2016). Study of Sitatunga is thus important because its conservation is dependent on the

increasing human population which is consequently increasing pressure and demand for access to

wetland resources such as water, habitat and grazing land of livestock (Sinibaldi et al., 2004). In

general, sitatunga survival is dependent on water availability and sustainable wetland habitat

management as such any negative effects of inappropriate wetland resources management may

lead to decrease in populations of sitatunga.

Sitatunga is a highly valued trophy animal (Flack, 2015) and one of the key flagship species of

economic value for the tourism industry in Uganda (UWA, 2017). For example Sitatunga is the

key mammal species attracting tourists in Katonga Wildlife Reserve and other concession areas

such as Ssese Island, Mayanja and Ajai WR. Sitatunga sport hunting therefore provides a good

strategy to diversify wildlife-based tourism attractions in Uganda and with its unique and

specialized wetland habitat, has a great potential to become a major tourist attraction in the

wetlands which were previously non attractive tourist sites. This could increase tourism benefits,

especially to the local communities neighboring these wetlands. Therefore a well-regulated

hunting of sitatunga can provide crucial funds for conservation, especially in areas seldom visited

by mass tourists such as wetlands areas. However, sustainable harvest management requires

knowledge about populations and habitats (Camille & Boyce, 2017). Therefore detailed

information on the distribution, abundance and threats are of inestimable value in order to develop

management strategies to conserve sitatunga and wetland ecosystems. Additionally, developing a

system for assessing and monitoring the trends of Sitatunga population will acts as indicator of

changes in wetland ecosystem status as a whole.

Page 14: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

The main interest of UWA to undertake this study was to come up with Non-Detrimental Findings

(NDF) for sitatunga. However, in order to do this there is need for information on the elements

relating to the species such as population status, distribution, population trends, harvests, and other

biological and ecological factors, trade information and conservation status of the species within

the country as recommend by IUCN SSC (2016).

1.3 Aims of the study

The overall aim of this survey was to undertake a Non Detrimental Finding (NDF) of Sitatunga in

Uganda.

1.3.1 Specific objective

The specific objectives of the survey were to:

(i) Generate baseline information on the occurrence, distribution and relative abundance of

Sitatunga both inside and outside Protected Areas in Uganda.

(ii) Investigate and evaluate threats to the conservation of Sitatunga and wetlands

(iii) Assess local community knowledge on Sitatunga

(iv) Develop a monitoring framework for the abundance, distribution patterns of Sitatunga and

wetland resource use.

2. LITERATURE REVIEW

2.1 Species description, characteristics, distribution, habitat requirements and

behaviour

2.1.1 Origin and Species description

The origin of Sitatunga is unknown as fossil remains have not yet been found to date (Kingdon,

1982). Generally, Sitatunga are the most amphibious antelope in Africa. They are semi-social,

sedentary animals, with small home ranges and potentially high density (Estes, 1991; Kingdon,

1982). There is difference in the sizes between Sitatunga subspecies across Africa. The East

African sitatunga is the smallest and the forest subspecies, the largest (Furstenberg, 2018). The

shoulder height of an adult male sitatunga ranges from 75 to 125 cm, depending on the subspecies,

and the body mass ranges from 40 to 120 kg. Adult males of the Zambezi sitatunga average height

of 90-100 cm and average mass of 115 kg (Beudels, et al., 2008). As with most antelopes, Sitatunga

females are distinctly smaller than the males, having a mean shoulder height of 75-80 cm and

average mass of 40-55 kg (Furstenberg, 2018). Sitatunga and Nyala females are smaller and are

referred to as ewes rather than cows. The pelage is woolly and water resistant with hair of up to 70

mm on the throat, groins, lower flanks, buttocks and upper legs. Female Sitatunga are generally

bright chestnut-brown colored and immature males are rufous-red. As males mature, their body

gradually turn grey chocolate-brown or grey-black. Both sexes have characteristic white markings

on the face, ears, cheeks, body, legs and feet. Females have a prominent black dorsal stripe along

the spine and one white marking on the throat. Males acquire a second white marking on the

throat and grow a prominent mane around the neck. The coloration, markings and texture

of hair varies between populations in different geographical regions (Kingdon, 1982). The East

African Sitatunga adult males are grey-brown with faint shadow stripes and silky hair. The Nile

Sitatunga has exceptionally bright body stripes and thin, scanty hair, while the Zambezi sitatunga

males are dull dark-brown and black, or have less obvious, body stripes and long, coarse, shaggy

hair (Furstenberg, 2018). Only the bulls possess horns which are spiralled with 1.5-2 twists when

fully grown and have length of 45-90 cm which constitutes the trophy which is of high interest and

value to the professional hunters. The horns of Sitatunga are inferior compared to that of an adult

greater kudu that has horns of 150 cm and 3.5 twists. The horn buds of Sitatunga bull appear at an

age of 6 months. The horns are ivory tipped when fully developed (Furstenberg, 2018). The

hooves are extremely long, narrow and average up to 10 cm long but can reach up to 18 cm on the

front feet and 16 cm on the hind feet of old bulls. They have extended, lateral false hoofs 2.5-3 cm

Page 16: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

long. Due to their length, the false hooves are often printed in the spoor as round dots behind the

hooves. The spoor of the front hoof is longer and thinner than the hind and is more widely split at

the front. The joints of the feet possess a unique flexibility and, combined with the special hoof

form, is a specialized adaptation for moving on marshy surfaces. The hoof form makes

Sitatunga movement very clumsy on dry or broken terrain.

2.1.2 Distribution of sitatunga across Africa

Sitatunga is one of the most poorly researched animals due to its inaccessible habitat (Beudels –

Jamar et al., 1997). The former range of Sitatunga included the areas of West Africa south of the

Sahara and parts of the Sahel. Sitatunga occurrence is restricted to the main land Africa and

probably occurred formerly alongside all waterways throughout the lowland forest zone of West

and Central Africa, extending into swamp systems in the savanna zones of Central, East and

Southern Africa (IUCN SSC, 2016). It is now rare and localized in West Africa, with a very small

and limited range in Senegal, Gambia, Guinea and Guinea-Bissau. However, it still remains

widespread elsewhere, from Benin through Congo Basin forests and in swamp systems within the

savannas of Central, East and Southern Africa as far as Okavango delta (May & Lindholm 2013).

It was long extinct in Niger and probably extinct in Togo, but have recently been confirmed as still

surviving in Ghana (May & Lindholm 2013). Kingdon (1982) and Palazy et al. (2011) listed three

main subspecies of sitatunga as (i) Forest sitatunga -Tragelaphus spekii gratus, (ii) Zambezi

sitatunga Tragelaphus spekii selousi and (ii) East African sitatunga-Tragelaphus spekii spekii).

These categorizations are centred on a river system or drainage basin. IUCN SSC (2016) provides

a general distribution of sitatunga in Africa (see figure 1). Furstenberg (2009) however categorized

sitatunga into five subspecies which are outlined with their distribution patterns across Africa

(figure 2), referred to below.

a) Tragelaphus spekii selousi (Rothschild, 1898), the Zambezi or southern Sitatunga, also

referred to as Selous’s Sitatunga

b) T.s. gratus (Sclater, 1880), the forest or West African Sitatunga

c) T.s. spekii (Speke, 1863), the Speke’s or East African Sitatunga

d) T.s. larkeni (St Leger, 1931), the Nile or Sudan Sitatunga

e) T.s. sylvestris (Meinertzhagen, 1916), from isolated islands in Lake Victoria.

The southern subspecies called Tragelaphus spekei selousi is found in the Bangwelu, Zambezi,

and Okavango basins. The Forest Sitatunga T.S gratus has the largest distribution range, stretching

from West African southwards through Central Africa, the Congo basin and parts of East Africa,

following the wet and humid regions of mainly tropical forests from Gambia to the Democratic

Republic of the Congo (Furstenberg, 2009). The East African Sitatunga termed Tragelaphus spekei

spekei is found in the Lake Victoria basin, covering Uganda, Western Kenya and Northern

Tanzania and is mainly confined to the shores of Lake Victoria. The Island sitatunga T.s. sylvestris

(Meinertzhagen, 1916) is found in isolated islands in Lake Victoria. The Nile Sitatunga T.s. larkeni

is restricted to the White Nile and its tributaries in southern Sudan, and the northern parts.

In the assessment of nationally threatened species for Uganda, WCS et al. (2016) indicated that

there were two subspecies of sitatunga in Uganda, which include Tragelaphus spekii sylvestris

(Ssese island sitatunga) which accordingly is globally categorized NE (not evaluated) and

nationally categorized as CR B1ab (v) critical with potential endemic because it is restricted to

Nkosi in Ssese Islands. Tragelaphus spekii spekii is categorized as least Concerned (LC) globally

because of being widespread in Africa, but is nationally rated as vulnerable (VU) B1b(i)c(i) due

to the high threats to its habitat. Based on the described distribution pattern provided by various

authors (Groves and Grubb, 2011, Furstenburg, 2018, Kingdon 1997 and Meinertzhagen, 1916),

there is an indication that Uganda may likely have three subspecies of Sitatunga i.e. the Nile

sitatunga (T.s. larkeni) distributed in the northwestern part of Uganda, along river Nile shoreline

towards the boundary with South Sudan, the East African sitatunga (T.s. spekii) in the Central parts

of Uganda and the T.s. sylvestris the island sitatunga restricted in isolated islands in Lake Victoria.

This makes Uganda as converging point for different sitatunga subspecies in Africa.

2.1.3 Habitat requirements and behaviour

Sitatunga are semi-aquatic and spend their entire lives in the close vicinity of open water habitats,

especially of marshes, swamps and floodplains bordering lakes and rivers with permanent water

(Furstenberg, 2018). The most essential requirement is permanent, open water and an evergreen

vegetation cover. This habitat is mostly restricted to tropical and subtropical regions between

13°N around Lake Chad and 20°S, and from the western coastline of Africa, eastwards to 35°E.

The optimal habitat is swamp with permanent water of depth of up to 1 m with dense stands of

Papyrus Cyprus, reed beds of Phragmites mauritianus and Echinochloa sp and beds of bulrush

Typha sp. bordered by an ecotone of terrestrial thicket or woodland. The reeds generally stand

Page 19: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

9

3-6 m above the water surface which provide camouflage to the mammals. Habitats with

shrubby growth, herbs, sedges, tall grasses and palms that border forest waterways are also used.

Sitatunga have been recorded to enter forest clearings, gallery forests and forest islands in

savannahs with permanent open water (Games, 1983).

Sitatunga spend most of their time in think vegetation during most of the daylight hours. In the

hot midday hours they rest in the shade among reeds on platforms made of debris or broken reed

(Furstenberg, 2018). In the cooler and darker hours they come out to feed and may take up to

late, often after 22hrs. They leave the wetland to browse vegetation in the neighboring dry land,

returning to the safety of the swamp up to mid-morning hours. When moving between the swamp

and the land they follow footpaths that can either be their own or the paths of other mammals such

as hippopotamuses. When feeding, they are usually solitary and spread over a large area but when

alarmed they become gregarious and aggregate while running for safety. Sitatunga are very shy

and avoid detection by crawling beneath thick vegetation. Danger is detected using a combination

of hearing and scent. Their sense of hearing is acute and splashing or movement of the reeds

causes them to flee for a distance of between 50-100 m. They then stop to re-evaluate the situation

and continue to feed once they are no longer under threat (Furstenberg, 2018). They are good

swimmers and Carpenter (1929) reported that sitatunga swims between different islands within

Lake Victoria islets. If seriously alarmed, they dive under water and swim towards deeper water

with only the nostrils showing. A bull defends itself by attacking aggressively when cornered,

while restless and alarmed males often bark. When feeding, the presence of sitatunga is often

revealed by the breaking of reed stems (Furstenberg, 2018). Ewes have nocturnal sneezing call

and bulls following a ewe, produces a high-pitched mewing sound.

2.2 Ecology and populations of sitatunga

2.2.1 Feeding and home range

Sitatunga are selective mixed feeders of grass, sedges, water plants and terrestrial grass, forbs and

browse shrubs and small trees. In isolated wetland in South Western Uganda Ndawula, et al.

(2013) reported that sitatunga feeds on young papyrus and reed shoots which account for 45% of

the dietary intake in the rainy season, rising up to 90% in the dry season, depending on the

height of the water level in the swamp. Browse lines have been recorded on knob-thorn (Acacia

nigrescens) and jackal-berry (Diospyros mespiliformis) trees. In common with the dik-dik

(Madoqua kirkii) and the gerenuk (Litocranius walleri), sitatunga stand on their hind legs to reach

the flowers and seeds of sedges and tall grasses. During the night sitatunga invade areas of

Page 20: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

10

agricultural pastures and planted crops (Ndawula et al., 2013). The territorial behaviour of

sitatunga has not been widely described although it appears to be restricted to mature bulls during

the peak periods of mating (Furstenberg, 2018). Home ranges are small and are defended by the

resident male of the family group. Home range size differences are due to high, localized sitatunga

densities that affect alternating social behaviour between solitary and gregarious. Home range

sizes also vary with the area of individual habitats and the presence of other competitors in the

niche such as lechwe and Kobus (IUCN/SSC, 1998). Temporary mass gatherings and sharing of

food sources indicate a high degree of tolerance between sitatunga and allows for major degree of

home range overlap. Sitatunga are either solitary or aggregate in small family groups of up to 15,

consisting of an adult male, an average of three ewes, and juveniles of both sexes. Small family

groups account for 4% of the population and male/female pairs, 35%. Adult males not associated

with family groups are usually solitary and account for 46% of the population. Sub-adult males

leave the group at the birth of the next offspring at 7.5 -10 months and form small, nomadic,

bachelor groups of 3-4 individuals (Peter, 2015). Juveniles often form temporary crèches of 3-5

in number. In densely populated habitats, family groups tend to be more tolerant of each other and

often form multiple, mass groups of up to 40 animals (Peter, 2015). The group size could be a

direct consequence of food abundance. A spatial distance of at least 1-2 m is generally maintained

between individuals allowing little physical body contact (Games 1983). A hierarchy of

dominance exists between females in a family group. Individuals frequently interchange between

family groups, indicating a lack of tight family bonding (Kingdon, 1982).

2.2.2 Reproduction, development and predation

Sitatunga has a high reproductive rate of 80-100% in adult ewes and up to 45% of female

population can reproduce twice a year. In females oestrus occurs every 20 days and lasts for 2

days during which time the bull attempts 7-12 matings per day (Games, 1983). Gestation lasts

for approximately 165 days after which a single lamb is born, either in a swamp on a platform of

debris between the reeds, or in thicket in the forest. The mother hides her sibling for up to 2

weeks. Ewes have 4 teats and suckling continues until an age of 4-5 months. The very young

are unsteady and stumble on their long hooves when moving over land or crossing reeds (Games,

1983). Once in the water they dive to escape danger. Birth intervals range from 5.5-9 months,

depending on environmental factors and animal density. In larger family groups, several ewes

in the group are mated with subordinate males that steal in during the night to mate, although

very few of these attempts result in conception (Games, 1983). The young of forest Sitatunga have

a survival rate of up to 80% before weaning (IUCN, 1974). Using these figures, a group of 19

Page 21: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

11

forests Sitatunga with 8 adult ewes in their natural environment have a mean, annual population

growth rate of 55%. Sitatunga densities of 55-200 animals per 100 ha in optimal habitat have

been reported, although their long-term sustainability has not been established (Games, 1983).

The common predators of Sitatunga are crocodile, leopard, python, hyena, lion, feral dogs and

man (Kingdon, 1982). Excessive flooding resulting in the drowning of young sitatunga and

permanent drying of marshlands by human development are additional threats. Sitatunga

frequently fall prey to the predators when leaving the swamp at night as they are waylaid along

the way back (Furstenberg, 2018).

2. 3. Sport/Trophy Hunting and Conservation of Sitatunga

Sport hunting, also known as trophy hunting, game hunting, and safari hunting, involves the

hunting of wildlife for sport or recreation and not primarily for food or sustenance (Yasuda, 2012).

This old form of recreation remains active today, and the significance of consumptive wildlife

tourism, including sport hunting and sport fishing, has been increasingly highlighted (Lovelock

eds., 2008). Africa is considered as “Mecca” or “home” for sport hunters from all over the world,

and over half of Sub-Saharan African countries officially authorized sport hunting (Roulet, 2004).

More than 18,500 hunters, mainly from USA and Europe, visit these countries each year,

generating annual gross revenues of at least US$201 million (Lindsey et al., 2007). Trophies

include, but are not limited to parts—such as elephant ivory tusks, rhino horns or deer antlers—to

entire heads that can be mounted on walls or complete bodies that can be formed into life-like

poses by a taxidermist (Humane Society of the United States, 2016). Trophy hunters display their

trophies in their homes or offices. Some researchers have argued that sport hunting plays an

important role in the tourism industry and community conservation and might represent a

“breakthrough” wildlife conservation strategy for Africa. This theory appears to be based on the

“success” of community conservation project focused on sport hunting in Southern Africa, such

as CAMPFIRE in Zimbabwe and ADMADE in Zambia. Wildlife conservation on private lands

has also been deemed successful. For example, private land owners in Namibia and South Africa

have converted cattle or farm ranches into game ranches, and more income has been generated

through wildlife conservation and use (hunting, cross-breeding, selling) than by farming and

grazing (Barnes & Brian, 2009; Child, 2009). Jones (2009) considered the benefits and costs to

local people of community-based natural resource management (CBNRM) programs in Botswana,

Namibia, Zambia and Zimbabwe. He concluded that although actual livelihoods or poverty

Page 22: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

12

impacts of benefits were difficult to measure, CBNRM could provide a range of benefits to

local communities and even small amounts of cash could have significant impacts on livelihoods.

Trophy hunting is controversial, prompting questions of sustainability, equitable treatment of user

groups, and ethics (Nelson et al., 2016). For the developing world, however, trophy hunting can

provide crucial funds for conservation of wildlife and habitats, especially in places with limited

tourism potential (Lindsey et al, 2007 and Minin et al., 2016). One reason for skepticism of trophy

hunting is sparse data and limited monitoring to form the basis for harvest quotas for target species

(Nelson et al., 2016). There is however lack of consensus among conservationists as to whether

trophy hunting represents a legitimate conservation tool in Africa (Lindsey et al., 2006). Hunting

advocates stress that trophy hunting can create incentives for conservation where ecotourism is not

profitable. However, for conservation outside of parks to be successful, sufficient revenues must

be generated from wildlife to offset opportunity costs associated with protecting wildlife and

habitats on the private or community lands. Sport hunting represents one means of generating

revenues from wildlife, and which has proven successful in creating income from and for several

major national parks and privately owned wildlife areas in Africa (Lindsey, 2006) and to a lesser

extent communally owned wildlife areas (Barnes, 2001; Kiss, 2004; Thirgood et al., 2006).

2.3.1. Trophy/Sport hunting and its potential role in promoting biodiversity conservation

Sport hunting has been practiced as conservation and livelihoods enhancement tool across the

African continent. Countries in the Southern Africa adopted this strategy and results have been

positive, ecologically and economically (Ochieng, 2011). In the developing world, trophy hunting

offers incentive to landowners to preserve hunted animal species and their habitats (Lindsey et al.,

20007, Bunnefeld et al., 2013). Trophy hunting is the most profitable form of consumptive wildlife

utilization, and represents a large and growing industry in several parts of Africa (Child, 2000).

For example, trophy hunting generates US$65.6–137 million per year in South Africa (Van der

Merwe, 2002; Damm, 2005), US$27.6–36.1 million per year in Tanzania (Baldus & Cauldwell,

2005), US$18.5 million per year in Zimbabwe (Booth, 2002) and US$12.6 million per year in

Botswana (ULG Northumbrian, 2001). These revenues provide economic justification for wildlife

as a land use option over vast agriculturally unproductive areas. Positive aspects of trophy hunting

as a conservation tool include a low off-take rate and a focus on males (typically 2% of male

populations), both of which do not in the long run jeopardize wildlife populations. These evidences

indicate that trophy hunting can play a key role in endangered species conservation (Leader-

Page 23: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

13

Williams et al., 2005). Trophy hunters pay higher fees per client than conventional tourists (Baker,

1997; Lewis & Alpert, 1997); therefore, revenues can be generated from lower volumes of people,

resulting in potentially lower environmental impact (Gosling, 2000; Mayaka et al., 2004).

Advocates for sport hunting also point out that trophy hunting generates revenues for conservation

in areas that may not be suitable for tourism, such as those lacking attractive scenery or high

wildlife densities (Leader-Williams & Hutton, 2005). As reported by Gerhard (2015) in African

Indaba Stewart Dorrington, a former president of the Professional Hunters’ Association of

South Africa and a life-long game rancher, puts it simple: “My hunting price is $2,500 for a kudu,

more than 10 times what the meat of one of these antelopes would bring. If you stop hunting,

the market is going to change completely; it’ll go to meat value, really; less than 60 cents

a pound”. As further reported by Gernhard (2015) that Vernon Booth, a Zimbabwe-based

ecologist who worked in African wildlife management for 30 years, said that “lions were now

protected because of the high value attached to them [by hunters]. Locals tolerate wild animals

because of the income that trickles down to them. Without the hunt money, locals would

increasingly poison lions, which are considered dangerous to people and livestock. One of

the successful innovations across African continent is the Communal Areas Management

Programme for Indigenous Resources (CAMPFIRE) programme which is a long-term

programmatic approach to rural development that uses wildlife and other natural resources as a

mechanism for promoting devolved rural institutions and improved governance and livelihoods

which is based on using the trophy hunting revenue. The cornerstone of CAMPFIRE is the right

to manage, use, dispose of, and benefit from these resources in sustainable manner. Between 1989

and 2006, CAMPFIRE income, mostly from high valued safari hunting, totaled nearly USD$ 30

million, of which 52% was allocated to sub-district wards and villages for community projects and

household benefits. Whilst a number of assumptions underlying the success of CAMPFIRE as an

innovative model for CBNRM have yet to be met, CAMPFIRE confirms the concept that

devolving responsibility and accountability for natural resource management can be highly

effective for the collective and participatory management of such resources (WWF, 1997).

Sitatunga is one of the highly rated antelope species by the professional hunters due to its

significance as a trophy animal (Lindsey et al., 2006). It can provide an important economic

incentive for conservation of the species and its habitats (IUCN/SSC, 2016).The hunting zones

adjoining national parks and equivalent reserves thus have the potential to play an increasingly

important role in the conservation of the Sitatunga (East 1999). A 21-day all-inclusive hunt of a

leopard may cost USD$35,000, an African elephant bull hunt may cost USD$40,000-70,000, a

Page 24: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

14

crocodile under 9 feet hunt may cost USD$6,000, a caracal hunt may cost USD$1,000, a baboon

hunt may cost USD$690 and a jackal hunt may cost USD$375.32 (Ochieng 2011). The trophy

price for sitatunga varies from USD$2451 to 4500 depending on the subspecies (Palazy et al.,

2011). Compared to other countries across East and Southern Africa (such as Tanzania, Zimbabwe,

Namibia and South Africa), Uganda is running a small scale sport hunting program, mostly outside

protected areas where wildlife populations are still low. As a result UWA uses a precautionary

system in this case 2% maximum off-take level used to determine the quota allocations. Booth &

Chardonnet (2015) recommend that, a sustainable hunting yield can be achieved within a range of

1-3% of the population. Sitatunga is among the most highly prized mammal species that sell

Uganda hunting safaris (UWA, 2018).

2.3.2 Sport/Trophy hunting in Uganda

Within Eastern Africa, Uganda started implementing sport hunting on private or communal land

in the parishes around Lake Mburo National Park in 2001. It was aimed at changing the long

history of human-wildlife conflict and to deliver financial benefits to communities around Lake

Mburo National Park (Ochieng, 2011). The Uganda Wildlife Policy (1999), the Wildlife Act (Cap

200 of 2000) and the UWA Community Conservation Policy (2004) all recognize the contribution

of wildlife to the well-being of humanity and highlight the need to share the benefits accruing from

wildlife if wildlife conservation is to be meaningful (UWA 2010). Sharing of benefits from wildlife

is also important incentive in promoting positive attitudes, knowledge and change of behaviour of

the neighboring communities and the general public towards wildlife conservation in general.

Uganda Wildlife Act (Cap. 200 of 2000) further provides six wildlife use right classes under which

the general public can benefit from wildlife. UWA started implementing wildlife use rights (WUR)

class A (Sport hunting) since 2001 on pilot basis in accordance with the Uganda Wildlife Policy

1999 and section 29 of the Uganda Wildlife Act 2000. Wildlife use rights was envisaged as an

incentive to promote the conservation of wildlife outside Protected Areas (PAs) and eliminate the

negative perception by community who still regard wildlife as Government property and of benefit

to only foreign tourists (Ochieng 2011). Granting Sport hunting use right depends on viable

population of target species and appropriate monitoring and enforcement systems. The case of

class A WUR was developed considering that there was an increased illegal hunting, changing

land uses and degradation of wildlife habitats in the country's land landscape (UWA 2010). This

was an issue of concern with regard to wildlife conservation outside protected areas. The attitude

of communities towards the wildlife and protected areas was not conducive for wildlife

Page 25: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

15

conservation. For example in the private ranches around Lake Mburo the pastoralists on whose

land the wild animals reside perceived them as a problem because they were destroying their

property and competing with livestock for pasture, water and salt leaks (Ochieng, 2011). The

residents on ranches saw wildlife as useless and destructive, and this attitude encouraged

promotion of illegal hunting. There was needed to save wildlife resident on the ranches and give

value to the wildlife as an incentive to the landowners to manage and protect it. This resulted in

the piloting of the first sport hunting in Uganda in Lake Mburo National park. In August 2001

UWA in collaboration with Rurambiira Community Wildlife Association, a community-based

organization signed an agreement with Game Trails (U) LTD (a company licensed by UWA to

undertake a pilot professional sport-hunting program) to implement a one-year sport-hunting pilot

project, on private ranches number and the government ranch around Lake Mburo National Park .

An evaluation of the pilot project by Ochieng (2011) found that through the community based

conservation, the communities in the three parishes were involved in decision making through

their Community Wildlife Associations (CWAs) which was instrumental in positively changing

the attitude of the communities towards wildlife and a large number of the communities were

reportedly protecting wildlife on their farms. Many had been involved in various projects (using

funds generated from sports hunting) to help improve household income which spread risks from

wildlife damages to other projects that were not easily destroyed by wild animals (Ochieng, 2011).

To expand the sport/trophy hunting UWA licensed five additional companies’ to undertake sport

hunting within some conservation areas and community hunting areas which still have populations

of wildlife animals. The concession companies include Uganda Wildlife safaris (UWS), Ateker

Safaris, Game Trails, Lake Albert Safaris and Karamoja Overland safaris with their allocated areas

of hunting blocks (table 1). Some of the annual quota set by UWA for various haunting block for

the various campsites targeting Sitatunga are indicated in the table 2, below. The hunting blocks

which have Sitatunga species include Ssese Island, Katonga Wildlife Reserve, Nsara Hunting,

Nakaseke, Nakasongola, Ajai Wildlife Reserve, Aswa-lolim, and Pian-Upe wildlife Reserve. As

indicated earlier the quotas were reported set using the adaptive management which is not based

on the scientific population estimates. General observation of the utilization of the quotas indicate

high demand for Sitatunga trophy which resulted in the complete/maximum utilization of the set

quota and additional higher request by the concession companies that were licensed to undertake

sport hunting in the various hunting blocks with Sitatunga (table 2). Uganda’s Class A quota in

most cases was based on the 2% maximum off-take level which was is applied to determine the

Page 26: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

16

quota for every year as recommended by Booth and Chard on net (2015) who suggested that, a

sustainable hunting yield can be achieved within a range of 1-3% of the population.

2.3.3. Case of benefit sharing from sport/trophy hunting proceeds in Uganda

Accordingly UWA records between 2008-2016, the sport hunting programme generated over

stakeholders which could induce positive support from the community.

2.4 Challenges to conservation of Sitatunga

There is a general declining trend in the abundance, distribution and population of Sitatunga

mainly caused by destruction of their natural habitats, competition with livestock and excessive

illegal off take by subsistence meat hunters and in many cases through the activities of poor rural

communities who lack alternative protein options (Manning, 1976). Sitatunga is among the

antelope species whose habitat is currently under threat from increased drainage of wetlands to

expand land for farming. In Uganda like in the rest of Africa, Sitatunga is adapted to survive mostly

in large swamps associated with extensive lake and river systems (Kingdon, 1982). Wetlands

provide habitat for a wide array of animal species, including Sitatunga by offering food, shelter

and protecting nesting sites. Human actions are a major cause of change in plant communities in

the wetlands such as modification or even complete alteration of vegetative communities which

may have diverse impact on their survival. Wetlands are very important in the survival of sitatunga

Page 28: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

18

because sitatunga is adapted to survive in wetlands/swamp conditions only and therefore any

artificial reduction of water flow and the reduction and degradation of wetland for other uses may

result in reduction of complete disappearance of sitatunga (Games, 1983).The wetland habitats

include areas of seasonally flooded grassland, swamp forest, permanently flooded papyrus, grass

swamp and upland bog. Around the world wetlands in its natural condition supply numerous

economic and ecological benefits to local communities, including water quality protection, flood

and erosion control, fish and wildlife habitat, aquatic productivity and unique opportunities for

education and recreation (Zahir & Nijamir, 2018). Wetlands are also valuable as ecosystems in

their own right, providing carbon storage, biogeochemical transformations, and aquifer recharge

(U.S. EPA, 2002). According to Dugan (1990), wetlands have been reclaimed Worldwide and are

still being reclaimed which diverts their original uses to new uses “regarded” as more profitable to

man and the rate at which wetlands have been destroyed is threatening their existence, leading to

an environmental crisis in many countries. Any degradation of wetlands affects ecosystem services

it provides negatively (Abila, 2002).

Uganda is immensly endowed with wetland resources. The percentage of Uganda’s area covered

by wetlands is estimated at 10.9% (MWE, 2017) of the country’s area, covering about 30,000 km2

of Uganda’s land area and is considered to be important ecosystems, which contribute considerably

to the national economy and rural livelihoods (Nature Uganda 2009). The wetlands comprise of

swamp (8,832 sq. km), swamp forest (365 sq. km) and sites with impeded drainage 20,392 sq. km

(MWE, 2017). Acording to NEMA (2009) most wetlands in Uganda occur outside of protected

areas. The key threats to wetland biodiversity in Uganda include, unsustainable resource

harvesting, habitat loss through agricultural conversion, urban settlement, industrial development

and burning (MWE, 2017). Negative impacts associated with wetland drainage include reduced

and/or loss of biodiversity such as the population reduction of Crested cranes (Uganda’s symbol)

while the Sitatunga or water antelope (Tragelaphus spekei Sclater), a globally threatened species,

has been eliminated from many areas due to swamp drainage. In many localities the raw materials

for traditional artisanal industries which were previously obtained from wetland vegetation are no

longer readily available as well as medicinal herbs (Nature Uganda, 2009).According to the

NEMA (2016) the regional status of wetlands and their level of degradation in Uganda are

categories as follows (i) in Eastern Uganda alone 20% of wetlands have been destroyed, Central

region 2.8%,Northern 2.4% and western 3.6% of wetlands have been destroyed (NEMA, 2008).

This has implications on wetlands biodiversity, especially for wetland dependent species such as

Page 29: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

19

Sitatunga. Current threats to wetlands and their biodiversity in Uganda (NEMA 2016) include the

following: (a) Encroachment of wetlands due to extended demand for land for grazing and

agriculture especially rice and other cereal crops in the Eastern region, dairy farming and

vegetables in South West and pastoral land in the North and East. This type of wetland conversion

is most common in rural and sub-urban areas. (b) Drainage of wetlands in urban centers especially

in the central urban area and region is driven by the force of urban expansion or development. (c)

Pollution of wetlands especially in urban places from discharging and dumping of untreated

industrial, municipal and household wastes while in rural areas from large agricultural farms and

mining areas. (d) Overharvesting or over-exploitation of wetland resources which includes

overfishing, overharvesting of wetland plants especially papyrus for domestic and commercial use

and harvesting of construction materials like clay, sand, firewood, timber, papyrus and ornamental

plants among others. (e) Siltation of wetlands; this is due to poor methods of farming surrounding

the wetland area that may cause massive erosion of soil into the wetland. All the above mentioned

constraints reduced the ecosystem service provided by wetlands.

2.5 Legal and Institutional framework for conservation of sitatunga in Uganda

In Uganda, legislative framework for species protection and illegal trade in wildlife includes the

Uganda Wildlife Act (2000) in addition to the Wildlife Policy (2014) and other sectoral policies

and legislations touching on wildlife and biodiversity protection. Such policies and legislation are:

the Local Governments Act, Cap 243 (1997), the National Forestry and Tree Planting Act (2003),

the Fish Act, Cap 197 (2000), the National Policy for the Conservation and Management of

Wetlands (1995), the Uganda Forestry Policy (2001). Other important regulations include the

National Environment (Wetlands; River Banks and Lake Shores Management) Regulations, 2000

Statutory Instruments. No. 3, which provides the legal framework for sustainable use of wetlands

in Uganda. Uganda developed an elaborate institutional framework for sustainable use of the

wetland resources. The legal framework devolves the responsibility to the Local Governments to

hold in trust for the people and protect the wetlands for the common good of the citizens of Uganda.

The statute guides on wetland resources to be utilized in a sustainable manner, compatible with

promoting continued existence of the wetlands and their hydrological functions and services. It

provides for regulation of activities to be undertaken in a wetlands.

Uganda ratified the CITES in 1991, and like a number of the Parties to CITES, does not have

specific legislation to implement CITES. Uganda has and continues to rely on the general wildlife

Page 30: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

20

legislation and Customs legislation to control trade in endangered species and their products

(Ayorekire et al., 2011). The illegal hunting and the national political unrest throughout the 1970s,

negatively affected wildlife populations, with some species, such as the white rhinoceros becoming

extinct in the country eco-systems (Kamugisha et al., 1997) and this led to a ministerial decree that

banned all forms of hunting in Uganda in 1979 to allow for wildlife regeneration (Ayorekire et al.,

2011). The decree for traditional hunting has not been lifted up-to-date. This basically means that

traditional or substance hunting is banned in Uganda and is thus illegal.

22

The study sites included; (i) Lake Opeta and Bisina wetland system in Karamoja and Teso regions,

(ii) Lugogo wetland system in the districts of Nakaseke, Luwero and Nakasongola, (iii) Mayanja

wetland system in the districts of Nakaseke, Kiboga and Kyankwanzi, (iv) Kafu River basin in

Masindi, and Nakasongola, (v) Katonga wetlands along River Katonga in Katonga Wildlife

reserve and (vi) Ssese islands in Kalangala districts.

3.2 Detailed description of study sites

3.2.1 Ssese Islands

Ssese Island is a group of Islands located in the North-western part of Lake Victoria, just south of

the equator (NEMA 2007). Bugala Island is the largest of the 84 islands making up Ssese islands

and is situated in the North-west of Lake Victoria (3r3'E. to 3r20'E, 0014'S to 0033'S) with its

western coastline is within two and a half miles of the mainland. Ssese Islands administratively

constitute Kalangala district in Uganda. The study was undertaken in Bugala Island which is

approximately 29,600ha, 58km long, 2-5 km wide and roughly S-shape. The grassland and forest

form a mosaic over the island and account for most of the vegetation. Swamps occur in shallow

waters and sheltered situations whilst resting farm land, containing a variety of herbs and

perennials was to be found in areas which had, until recently, been tilled. The study was

concentrated on Bugala Island due to strong waves during the time of study and thus other smaller

island were not visited.

3.2.2 Opeta-Bisina wetland system

Located in Eastern Uganda, this wetland system is a combination of the Lake Opeta Ramsar site

and Lake Bisina Ramsar site both designated in 2006 (Nature Uganda, 2009). Lake Bisina is a

shallow lake covering an area of 192km2 with a flood plain of 30km long and 6.5km wide. They

are both Important Bird Areas (IBAs). Together, this wetland system covers an area of 123,141ha

and is shared by the districts of Kumi, Katakwi, Soroti, Bukedea, Nakapiripiriti and Sironko

(Nature Uganda 2009). It is predominantly an extensive swamp of Hippo grass (Vossia cuspidata)

graduating into dry Hyparrhenia grassland savannas and the periphery is dominated by an

association of acacia and Combretum. Part of the system covers the Pian-Upe Wildlife Reserve

that provides a refuge for the local animals including Sitatunga during the dry season and also

when the wetland is flooded. Pian-Upe wildlife reserve is adjoined to the Bisina - Opeta wetland

system by a series of marshes and papyrus swamps. Lake Bisina and Opeta have emergent

vegetation mainly of sedges and floating vegetation dominated by water lily (Nymphaea) species,

patches of Cyperus papyrus submerged water weeds (Nature Uganda, 2009). The main inflow into

the Opeta- Bisina wetland system is through River Sironko. Several human activities with negative

Page 33: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

23

impacts in the catchment including rice growing, livestock grazing, papyrus harvesting and fishing

among others. The two lakes are very important to the surrounding communities in terms of

fishing, transport and supply of water for domestic and livestock use. A rhizome of the Nymphea

genus acts as a source of food during the dry season (Nature Uganda, 2009). Most of the wetland

fringes have been converted into rice schemes while other areas are being continuously degraded

through over use by livestock (Nature Uganda 2009).

3.2.3 Katonga river system

The Katonga River is located in the southwestern part of Uganda. Its channel is continuous

between Lake Victoria and Lake George, reflecting that it once drained away from Lake Victoria

into Lake George along its entire length. Regional uplifting events between the two lakes

associated with the western limb (Albertine Rift) of the geologically active East African

Rift system, caused the swampy region to the southwest of Lake Wamala to become the

new watershed for the Katonga River, which changed course to flow east into Lake Victoria,

augmented by several tributaries along its course. This watershed is located approximately 0°13'N

30°39'E near the Katonga Wildlife Reserve. Vegetation of the area around River Katonga and the

nearby Katonga Wildlife Reserve is characterized by savannah mixed with acacia scrubland or

woodlands. Also, the largest part of the wildlife reserve has either seasonal or permanent wetlands

but there are also patches of tropical forest and river line. In the 1960s, the reserve was home to a

variety of animals including the zebra, topi and eland. Between 1971 and 1985, most of the wildlife

was killed through commercial and subsistence poaching and some of these animals are being re-

introduced back into the reserve. Other mammals include Black and White Colobus Monkey, the

River Otter, and Olive Baboon, Uganda Kob, Waterbuck, Leopard, Buffalo, reedbuck, bushbuck

and duiker and chevrotain. The reserve is also home to various reptiles, amphibians and butterflies.

3.2.4 Mayanja and Lugogo river systems

Mayanja River is located in Central Uganda between 900 and 1100 M above sea level. The source

of River Mayanja is located in Wakiso, district and eventually drains into river Kafu near the

village of Ndede, in Nakaseke District. The river traverses or forms the borders of the following

districts: Wakiso District, Mpigi District, Kiboga District, Kyankwanzi District and Nakaseke

District. The length of River Mayanja, is approximately 150 kilometres (93 miles) from source to

end. Some of the wildlife species in the area include Hippopotamus (Hippopotamus amphibious),

Page 34: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

24

Nile bush back (Tragelaphus scriptus), Defassa water buck (Kobus ellipsiprymnus), oribi (Ourebia

ourebi), bohor reed buck (Redunca redunca), warthog (Phacochoerus africanus), bushpig

(Potamorchoes rus larvatus), and common duiker (Sylvicapra grimmia) (Camille & Boyce, 2017).

3.2.5 Lugogo River system

Lugogo river system is similarly located in the central part of the Uganda and flows in a north

easterly direction from the Kafu River. River Mayanja and River Lugogo are the two main

tributaries flowing through the vast permanent papyrus swamps before finally emptying their

waters into River Kafu. It is interesting to note that the spectacular landscape of River Kafu Basin

is mainly made up of thick bush thicket and verdant papyrus swamps.

3.2.6 Kafu River system

The Kafu River originates in the western part of Uganda, starting from a swamp approximately 12

kilometres, northeast of the village of Kitoma, in Kibaale District. It flows eastwards at first, then

it turns north, to empty into the Victoria Nile, approximately 8 kilometres, upstream of the town

of Masindi Port, in Masindi District. On its course eastwards, northeastwards and northwards, the

river traverses or forms the borders of the following districts: Kibaale District, Hoima

District, Kyankwanzi District, Nakaseke District, Nakasongola District and Masindi District. The

swamp, out of which River Kafu arises, is also transversed by another river system called River

Nkusi. At its source, River Kafu is at an altitude of approximately 1,100 metres. At its point of

entry into River Nile, the altitude is approximately 1,040 metres. Kafu River receives water from

various sources including Mayanja and Lugogo which are the major tributaries. The length of

River Kafu is approximately 180 kilometres, from source to end. The area surrounding the three

rivers is referred to as the "Cattle Corridor” because of the pastoral livelihoods that dominate the

zone. The wetland vegetation in Kafu basin is mainly dominated by Papyrus swamps and dense

bush thickets. The wildlife residents of the area include the East African Sitatunga, East African

Bush Duiker, East African Bohor Reedbuck, Nile Bushbuck, Ugandan Defassa Waterbuck,

Leopard, Common Oribi and Bush Pig among others.

3.3. Population estimate

Estimating population of Sitatunga through direct observation or direct sighting of the animals in

the wetlands is generally problematic (Birchers et al., 2002) because of the shy, elusive and

cryptic nature of Sitatunga and also because of the poor visibility in the dense wetland

vegetation. Due to these circumstance special methods are required to estimate the abundance of

Page 35: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

25

Sitatunga (Beudels-Jamar, 1997). Due to the inaccessibility of dense wetland habitats by foot and

the associated difficulties in distance sampling for population estimates, alternative techniques to

monitor and estimate population density are required (Camille & Boyce, 2016). Studies to assess

populations and densities of Sitatunga generally require longer time as were for most studies within

southern and eastern Africa (e.g. Maya Nord in the Republic of Congo (Magliocca et al., 2001 and

Camille and Boyce (2017) in Mayanja river central Uganda. Several indirect approaches have been

developed to address the problem of studying elusive species such as sitatunga and these include

the use of indirect signs such as, dung, nests, tracks and trails (Barnes, 2001 and Plumptre,

2000). The indirect signs can be used as proxy for the estimation of animal presence, distribution

and population. Advance systematic methods of indirect estimation of large mammal densities

include the use of camera traps (Noss et al., 2012, Tobler et al., 2008, Camella & Boyce, 2017),

video recording (Scheibe et al., 2008), and line transect method (Plumptre, 2000, Walsh and

White, 1999, Varman & Sukumar, 1995). Due to the limited time for this study the team adopted

line transect method using mainly boat navigation along natural channels in the swamp habitat.

3.3.1 Boat survey

For boat survey the method used by Beudels-Jamar et al. (1997) was adopted and used in five

locations; Katonga River, Mayanja River, Kafu, Lake Bisina-Opeta wetland system and Ssese

Island swamps which were more accessible. Lugogo River had very dense vegetation which was

rather difficult to penetrate. The Lake Bisina was an open area with highly degraded

periphery/shores where only human activities could be visible (Figure 8). In some sections of the

sites listed above visibility was restricted due to the tall vegetation which resulted in discontinues

or non-uniform use of the boat survey. The study adopted a modified sampling approach developed

for studying spatial and temporal variation in the abundance of songbirds (adopted and modified

from Ferry & Frochot, 1970; Gates et al., 1993; Gregory, et al., 1994) which was used by Beudels-

Jamar et al.(1997) at Parc national de Akagera in Rwanda to estimate population of sitatunga. The

approach used as described in Blondel (1986) in which observers stop at predetermined points

along transect and record the number of individuals of each bird species which they can hear

signing or calling within a fixed period. Surveys were carried out from a speed boat equipped with

a 15HP (Yamaha) boat engine or canoe powered by two persons which was driven at a speed of

1kilometers per hour, along the channel through the swamp in the river or along the edge of the

lake. Starting from a random chosen point, the boat was stopped every 5 minutes and the area

around was scanned with binoculars for 5 minutes. The number of individual sitatunga observed

Page 36: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

26

and their distance from the boat was recorded and the habitat types were also recorded. A total of

8 transects varying in length from 25 to 40 minutes were carried out at various times of the day,

from 06:30 to 18:30 between June 2018 to August 2018. This provided 37 sets of observations.

Based on previous experience Bueam et al. (1994) recommended sitatunga surveys to be

undertaken between 07:00 and 10:00 am which was followed during this study.

In order to provide additional information on sitatunga observations were carried out from about

10 meter high tower (Machans or observation tower) overlooking/ along the part of the swamp

(Figure 5). Observations were made from 06:00 to 19:00 in an arch of 150 in front of the tower

during 5 separate days in each site. The exact time of observations of the sitatunga and when it

disappeared from view were recorded. Its initial bearing and distance from the tower was estimated

using compass (suuto type) a rangefinder (Coleman Rangematic, with a precision of 3% at 40 to

300m). The measurements were used to plot movement of each individual on a chart of the area.

The animal was classified as male or female and adult or juvenile. Any details which could be used

to identify the individual (such as color, natural marks, and shape) were recorded to permit

recognition of individual animals on the same day but not different days. The weather conditions

were recorded every hour and classed as 1. Bright sunlight, 2. Partial cloud cover, 3. Complete

cloud cover. Along each transect route, additional data collected for analyses included the

direct indirect signs such as dung, track, nest, heard, feeding residue among others.

3.3.2 Recee walks

During the fieldwork additional information was collected from a combination of both recce walks

(not straight line transects but instead taking path of least resistance) and straight line

transects to obtain information on sitatunga presence, distribution and abundance . Both direct

and indirect methods of mammal census were used to indicate presence of sitatunga in the study

area. The use of spoors, tracks, prints, hairs, dens, scats and other animal signs is a standard

method for censuring wildlife when they are not easy to see, for example if they are

secretive, nocturnal or when habitat conditions impede visibility (Norton-Griffiths, 1978).The

field assistants were trained on field procedures and in particular the use of equipment

(Garmin GPS60 navigation, use of range finder and sighting compass), data recording,

identifying sitatunga sign, searching behaviour and general data collection protocol in addition

to strategies for social and cultural interaction with the local communities. Community

members from the nearby villages assisted in guiding the team during the field work. The survey

route followed approximately zigzag format based on easy of access and passage point, starting

from random point within the study sites. During recee walk the team used direct sightings of

sitatunga as the target animal, hearing of vocalizations, recording of tracks, presence of

dungs/droppings, and other evidences such as carcasses and skeletal remains to identify

sitatunga species. The recee surveys were carried out during the day. Night walks were not possible

due to security reasons. The survey team walked at an average speed ranging between 1 to 3 km

/hours including pauses of every 100 to 200 meters to listen to animal calls and record

Page 38: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

28

information on the data sheet. Animal sighting distance ranged widely but for dung/scat,

footprint, soil excavations, skeletal remains the average path width was 5 meters.

During recee walks it was only possible to differentiate the following categories; males, females,

infant/juveniles. The observations and measurements were recorded on a standard data sheet

(appendix 1). The field team members consisting of three persons carefully searched the ground

for dung remains. The state of decomposition of the dung and vegetation type at that location

was recorded in the data sheet in appendix 2. The Dung pellets were identified using field guides

to mammal signs by Louis (1992), Chris and Tilde (1994, 2003) and Clive (1996). The GPS way

points for each observation were recorded together with habitat type. The foot prints or tracks

were measured in length and width to the nearest millimeter when identifying the tracks of

sitatunga. Other opportunistic information collected during the survey included skeletal (skull

and other bones) or carcass remains of the animals when found.

3.3.3 Habitat (Vegetation) description

Vegetation forms an important habitat for the mammal populations as it serves as food and resting

/hiding place. Along the survey route, vegetation types were recorded. The overall study path

followed transects which passed through major representative habitats of the study area. A simple

vegetation classification system, based on obvious dominant plant species was used. The dominant

plant species were identified in the field or specimen collected, pressed and identified using plant

identification guide by Eggling (1951) and Katende et al. (1995).

3.3.4. Human activity/factors threatening Sitatunga

Information on human activity/disturbance of the sitatunga habitat is important because it helps

to assess the threats to the species and general biodiversity of the areas. During recee walks the

research team recorded observations of human presence in the study area. Common signs of

human activities recorded included resource extractions, settlements (huts), farmlands, and

building of access roads or paths to the newly established homesteads and farms, thatch and

broom grass collection, pole collection, collection of fire wood, charcoal making, collection

of wild rope, fruits, medicinal plants among others. Additional information was obtained from

non-formal interactions with the communities members during visits to the study sites.

Page 39: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

29

3.4. Data analysis and presentation

3.4.1 Distribution information

The GPS locations of animal sightings, spoors and evidence of human activities we rerecorded

and used to plot distribution maps using Arc-GIS 10 (Arc-map version 9.3) software

programme. Correlation/regression analysis was used to investigate the relationship between

relative abundance of sitatunga signs and level of human activities in the study area. Additional

information on distribution of sitatunga was obtained from the previous studies undertaken on wild

mammal species survey by different researchers within various parts of the country and form UWA

library and reports.

3.4.2 Analyses of the occurrence and distribution of human threats

To facilitate the analysis of the effects of human factors on mammal species, signs recorded along

transects were grouped into eight categories. Analysis of the encounter rates of human threat

categories in the study areas and analysis to show the relationship or association between threats

and Sitatunga encounter rates in the study areas were done using SPSS. For each sign

category, indices of human pressure including index of abundance of human threat category for

the sampled area, index of abundance of human threat category per transect, and index of

abundance of human threat category per site were analyzed to show the intensity of human

influence in the study area. Encounter rates (ER) of human signs recorded from sampled area were

calculated as:

ER = Count of each sign category………………………………………

Transect length covered (km)

Encounter rates of signs of human disturbance recorded from recee walks/survey were also

analyzed. Frequencies of occurrence of the different human threat categories were analyzed to

determine distribution of threats. Spatial data collected with the aid of Garmin 60 and 62 GPS

hand held devices on the various human signs that were noted in the study area were later entered

into ArcGIS 10 programme for visual analysis to show the distribution.

Page 40: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

3.5 Community knowledge on the distribution and occurrence of Sitatunga

Sitatunga is particularly difficult to survey in a short space of time thus in addition to the field

observations we relied on local knowledge of hunters and other community members to identify

the species in the study sites. This is a wieldy acceptable method used by mammalogists to compile

species lists. These interviews were carried out while being guided using the photographic plates

from reference books such as Kingdom field guides to African mammals by Kingdom (1997),

Chris & Tilde (2008) and Clive (1996). Residents of the villages were interviewed using guideline

provided in appendix 2 using local languages.

3.6 Determination of quota for sitatunga sport/trophy hunting

Sport/trophy hunting is provided under Section 29 of the Uganda Wildlife Act Cap. 200, UWA

adopted wildlife use rights (Class A –E) as a tool of sustainable management of wildlife outside

protected areas.In wildlife management, a quota represents the number of animals that can be

safely removed/harvested from a population each year without biologically reducing that

population. Setting quotas ensures that wildlife populations maintain themselves and continue to

survive biologically into the future (WWF, 1997). Quota setting for sport hunting is aimed at

providing the number of target animals which may be killed by sport hunters so that there is no

decrease in the number of trophy animals over time. In order to determine the quota off-take it is

important to establish maximum yield. To do this we need to have an idea of how many animals

there are and how many of these animals can be used. Some key factors considered while setting

quotas are; information on the animal populations, fecundity, sex ratios and the level of threat of

the animal species in an area. The use of comprehensive information sources is to ensure that

species utilization does not threaten their existence in the wild. A combination of local knowledge

and scientific methods greatly help the process of establishing animal numbers and setting quotas

as was undertaken during this study. There are many factors which influence quota setting and this

is linked to the growth rate of the population. There are many natural factors which can speed up

or slow down the growth rate in a year or over a number of years. Additional information on the

sitatunga population ecology and behaviour was obtained from reference sources such as Games

(1983), Owens (1983), IUCN/SSC (2016), IUCN (1974), Kingdom (1997), Furstenberg (2008)

among others. Based on the available information and the current population data and site specific

conditions maximum off-take rate of 1 to 2% is proposed for use in determine quota.

4. RESULTS

4.1 General observations on sitatunga activity

The study team observed the daily activity of the Sitatunga which was characterized by careful

period of inactivity (freezing) at frequent intervals. This was probably to provide time /opportunity

to sense danger of predators within the vicinity. In some cases it was difficult to sense presence of

a Sitatunga if one had not marked its location before as it stood still in order to camouflage itself

from any dangers. Similar behavior was reported by Beudels –Jamar et al. (1994) who attributed

the possibility of detecting a Sitatunga during a survey to its level of activity at the time of

observation. The time when the sitatunga was seen were mainly early in the morning hours (6; 30

to 8:30 hours) and evening hours (17:00 to 19:00 hours). Sitatunga were generally not very active

in other times of the broad day light and could not be located, suggesting that they were probably

hidden in the thick habitat of the swamps. Thus the detestability of sitatunga was related to the

time of the day and weather conditions as indicated by the figure 8 in which the activity levels, the

percentage of time that each individual was visible from the machan/observation tower varied

during the course of the day was not affected by distance for animals within the 350 meters of the

observing point. The sitatunga were most active between 6 and 10 hours and evening between 17

to 19 hours (figure 6).

Figure 6 Variation with time of the day in the average percentage time that individual sitatunga were

visible from an observing platform

There was a significant difference in activity between different times of the day (F= 2.945 <0.01)

and weather conditions (F = 3.3 p <0.01) but not sex of an individual. In general the level of activity

of sitatunga was likely to be affected by time of the day. Figure 7 indicate the variation of the

observed density of Sitatunga with the distance from the observation plat form. It was observed

that in Mayanja river site vegetation (papyrus) was deliberately cut to initiate sprouting which

formed good quality (young papyrus) feeding resource (figure 8) and thus provide a clear vision

for observation of Sitatunga while feeding in more open vegetation. Under such conditions the

observation was not affected by the distance from the platform except where it was concealed in

the sites that are not open. As such the detectability of an active Sitatunga which is was presumed

was not affected by the distance from observer as long as the animal was within the 350m of the

observer. The density was fairly less variable between 225 and 350 which suggests that within the

350 m (figure 7) density may not be affected by the distance from the observer.

4.2. Estimation of density

To convert the individual counts made from the boat or point of stopping along the shoreline to

the estimates of density, there was need to determine for each area around the point of observation

the probability that an animal which was present within that area would be detected by the

observer. This depends on the degree of vision obstruction by vegetation, the activity pattern of

the animals and the disturbance introduced by the observer (Beudels –Jamar et al., 1994). It was

assumed that active animals were always detected within the entire radius of observation from the

sampling point, up to the maximum distance of observation recorded, that inactive animals are

never detected and that disturbance did not in itself provoke activity (Beudels –Jamaretal. 1994).

The second model proposes that all animals originally situated within a distance d1 of the boat

were detected only if active, on a surface reduced by obstacles to vision beyond d2. Distance d1

and d2 may not be accurately determined but for the case of this study it was observed to be on

average 60 meters and 120 meters respectively. The probability of detection was determined by a

combination of the level of activity of animals at that particular time of the day, and the number

of periods of activity at the time of the day. The probability of detecting an animal during an

observation period was expressed as the sum of the probability for the animal to be active at the

beginning of the observation period plus the probability that it begins its activity at any time during

the observation period. That is described by the following equation.

Dt =Ar + (1-Ar)Nrn T (adopted from Beudels-Jamar et al., 1994)

Where: Dt: is the detect ability at the time of day, T: is the probability that an animal which is

present in the effective area will be detected during a period of observation T (within 5 minutes in

this case). A: being the level of activity at the time of day t that the survey was conducted, and N:

is the number of periods of activity at that time of the day. Mean values of the day (06:30 -9:00,

10:00 – 10:59 and 17:00 -1959, and 11:00 – 16:59) were estimated from the data collected from

observation tower. The number of Sitatunga counted at each sampling point, the appropriate detect

ability and areas of visibility and the resulting density estimated are shown in table 4. For the five

sites (Mayanja and Katonga, Kafu, Opeta and Ssese sites) based on the second hypothesis. This

leads to an average density of Sitatunga in the various sites as indicated in table 4. The estimated

total populations of sitatunga in the study sites based on suitable habitats are indicated in table 5.

For this study dungs and tracks were used to provide indication of sitatunga encounter rates in

various sites of the study. The overall mean relative abundance of dung and track signs per

kilometer in the study areas is indicates in table 7. The results show that the least number of dung

and track signs of sitatunga was recorded in Lake Opeta site. This was expected considering that

during the study period area were flooded and most of sitatunga could have migrated to safe sites.

As shown in table 7 sitatunga signs were most abundant in Mayanja, Kafu and Ssese Island

(Bugala) sites as indicated by their comparatively higher mean spoor encounter rates, starting from

1.1 and above. The encounter rates of dung spoor were generally low for most sites but lower for

Lake Opeta sites. This may be attributed to the flooding which was experienced during the study

period in Lake Opeta/Bisina sites. Results suggest that for every kilometer walked in the respective

study sites, one would find 70 time more dung and tracks per kilometer in other sites compared to

Lake Opeta sites which may be due to the annual flooding pattern of the sites during the year.

4.2.4 Distribution of sitatunga in the study sites

The distribution of spoors and siting of sitatunga in various study sites is indicated in the figures

from 9 to 14. All the recording indicates that observations of sitatunga were located within the

wetlands or close to the wetland or along riverine forest. Only one sitatunga carcass (Figure 15)

was recorded along the periphery of Katonga River wetland. The victim could have been caught

when it had moved into the nearby riverine forest to forage. In Bugala Island (Ssese Island) one

male sitatunga (figure 16) was identified which was kept captive in an enclosure under the

management of Ssese Island Beach Hotel.

4.3. Distribution of sitatunga across Uganda

The 17 shows distribution of sitatunga in various parts of Uganda based on the wild animal studies

in different parts of the country and data base of UWA. The general pattern indicate that the

Page 50: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

40

sitatunga had wider distribution across Uganda. Figure 18 shows potential areas cross Uganda

where sitatunga could be found. Based on the information that sitatunga can persist in its natural

habitat provide the habitat is less disturbed (Kingdon, 1997), it is possible that relatively intact

patches of permanent wetland habitats within Uganda that may be hosting of sitatunga.

3.3. Habitat types

3.3.1. Vegetation description

The vegetation of study area was grouped into five broad categories:

(i) Riverine/Gallery forest (RF) vegetation: Consisted of riverine or gallery forest (figure 25.).

This was mainly found along permanent water courses and sometimes along swampy

wetland shores. The common tree species included Acacia gerdi, Acacia abyssinica,

Acacia Senegal, Balanities aegyptiaca, Afzelia africana, and Khaya senegalensis.

Page 52: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

42

(iv) Flood plains (FP): (figure 26) were found in low lying areas and valleys adjacent to the thick

woodlands with permanent water. The vegetation was dominated by spear grass (Imperata

cylindrical) with scattered shrubs and trees mainly consisting of Piliostigma thonningii,

Balanities aegyptiaca, Acacia species and Kigelia africana.

(v) Swamp vegetation (SV): This was restricted to the river/lakes and permanent swamps. It was

dominated by Papyrus species such as Cyperus involucratus, Pennisetum purpureum and

Brachiaria species.

Figure 20 Flood plains in Lake Opeta area which was flooded during the study in July 2018.

4.4 Human disturbance activities

The main types of human disturbance recorded included; Collection of thatching grass

(Hyparrhenia species)/papyrus, tree cutting for fire wood/poles for housing, charcoal making and

clearing areas for crop cultivation, livestock farming and sand mining/bricklaying. The prevalence

of the key human disturbance activities in various study sites is indicated in table 8. Other human

disturbances included bush burning to facilitate hunting of wild animals, clearing of land for

agriculture and sand extraction. Some of the threats recorded along transects and recee walks,

respectively in the study areas are illustrated in figures 21 to 23. Figure 24 summarizes various

human activities taking place in the areas while figure 25 compares average levels of all activities

in all study sites.

The general relationship between mammal distribution pattern (using the spoors) and intensity of

human activities was examined using Spearman rank correlation tests The findings indicate that

there was highly negative correlation (r -0.585, p<0.01) for Bisina-Opeta site. An assessment of

the contribution of human activity to the occurrence of sitatunga signs using regression

analysis (R2 0.342, P<0.01) indicates that it contributes about 30% to the species occurrence.

This suggests that various human activities negatively impact on occurrence of sitatunga in the

study sites.

4.5 Local community knowledge on sitatunga

The questionnaire was administered to total of 131 respondents drawn from the six study sites.

The majority (86%) of the respondents were male perhaps because most participants involved in

digging around the wetlands were men. Women mainly got opportunity to reach swamps when

Page 56: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

46

going to fetch water. The age of the respondents ranged from 23 to 76 years with the majority

between 4o to 50 years and had stayed in the location for over 10 years. Due to the rural nature of

the study sites most respondents were peasant farmers or cattle keepers (86%) who occasionally

engaged in fishing. The only few respondents in the Mayanja river site were casual laborers at the

landing sites or farms. The framers engaged in mixed cropping in all sites mainly consisting of

sorghum, millet, cassava, rice, vegetables crops such as tomatoes among others. Locally sitatunga

was known as “Njobe” in Lutoro, lunyoro or Luganda which were the predominant language

spoken at the study sites other than the iteso. The respondents had very good description of general

ecology and behaviour of sitatunga which was in agreement with available published information

such as that in Kingdon (1982). Most of the respondents had seen sitatunga and described it as

medium sized mammal with the males being bigger with horns while the females were smaller and

hornless. In distinguishing sitatunga from other mammal species the respondents used the long

pointed and wide splayed hoof by using forked fingers. They similarly indicated the time when

they saw sitatunga was either very early in the morning or late in the evenings when the suns was

not bright. The individuals who were expert hunters indicated that sitatunga follows tunnels when

going or coming back from the grazing sites. All respondents reported that only one baby was born

at a time. Some respondents had observed sitatunga swimming in the water when escaping from

predation. They reported that sitatunga rest in shade during hot day time and that the males were

more aggressive than the females and that sitatunga barks occasionally. They reported that

sitatunga mainly moves individually and rarely in groups except the females that move with their

juveniles. All respondents indicated that it was usually difficult to detect sitatunga because of the

behaviour of freezing or disappear into the wetland when disturbed. When asked on the future of

conservation of sitatunga, the majority of the respondents (90) reported that degradation of the

wetland vegetation was responsible and may lead to extinction of the species in their localities.

4.6 Guidelines for allocation of national sitatunga sport hunting quota

Quota setting provides the number of animals which may be killed by sport hunters per year so

that there is no decrease in the number of trophy animals over time. Based on the available

information on the sitatunga population an off take rate ranging from 1 to 2 % is recommended,

depending on the site conditions is shown in table 11.

Page 57: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

47

Table 11 Recommend off take for sitatunga in various study sites.

The low proportion of harvesting is recommended because genetic considerations provide for a

minimum viable population of 500 individuals (Bakuneeta, 2003) for successful long-term

conservation under natural conditions (Frankel & Soule, 1981).

5: DISCUSSION, CONCLUSIONS AND RECOMMENDATIONS

1.1 Discussion

5.1.1 Occurrence and population sizes of sitatunga in study sites

The accurancy of estimate of densities and popualtions depend on the estimated of the area of

visibiity at each of the sampling points in the study sites. Other biases may arise due to the survey

boat and becaosue some of the counts were made on the edge of the open water or swamp which

means the survey result is an approximation. Based on the result of this study, all study sites seem

to contain viable populations of the sitatunga which suggests that the sites are representative of a

suitable sitatunga habitats in Uganda. The popuation estimates obtained in this study were

moderate (raning from 5 to 23 animals per sqaure km). Some of the population density values

obtained in this study were slightly higher comnpared to other findings in the same site example

by Camille and Boyce (2016) in Mayanja swamp but lower when compared to the density estimate

values obatained elsewhere (such as in Akagera N.P 57-60 /km2(Beudels –Jamar et al., 1997),

64/km 2 in Busanga swamps (May & Lindholm 2019; East 1999) using other methods. The

distribution pattern of sitatunga indicate that these animals were closely affiliated to the wetland

systems with permanent water in Uganda.

5.1.2 Characteristics and intensity of threats affecting sitatunga conservation

The study sites experienced various threats from the diverse human exploitative activities as well

as developmental activities. Threat categories recorded in the study sites included; collection of

grass/papyrus, tree cutting for fire wood/poles/ charcoal making, clearing vegetation areas for crop

cultivation, livestock farming and sand mining/ bricklaying which all result in degradation of the

wetland habitat and thereby negatively affecting conservation of sitatunga. Of the categories of

threats, habitat destruction was perhaps the most severe as it was recorded in most sites. Elsewhere

human activities have been reported as responsible for causing the disappearance of wetlands,

leading to local extinctions of wetland dependent species. For example Nsabagasani et al. (2008)

reported that in Akanyaru wetlands in Rwanda populations of resident Sitatunga had disappeared

or were significantly reduced at Nyiramatuntu and Kinyovi. Habitat destruction was wide spread

in some of the study sites and could be responsible for low numbers of sitatunga signs reported in

Bisina /Opeta site. It was possible that sitatunga migrated away from the disturbed sites at Lake

Bisina area to Pin-Upe WR which was believed to be safer because it was partly in the protected

area. In Kenya sitatunga was reported to migrate when the conditions become unfavorable as

Page 59: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

49

documented by Kenya Wildlife Service (https://allafrica.com/stories/201206070081.html) where

hundreds of sitatunga were reported to have migrated from their natural habitats at King'wal

swamp to the neighboring wetlands after exposure to danger of burning. At Tisai Islands which

separates Lake Bisina and Lake Opeta there was massive vegetation removal for various proposes,

including firewood, charcoal production, clearing vegetation for livestock grazing. Ocen and

Andama (2002) similarly reported that sitatunga occurrence was reduced in areas with higher

human activities such as sites with removed papyrus and where livestock grazing was intense. This

could explain the lower numbers of sitatunga populations and sparse distribution recorded in this

study. Collection and extraction of plant resources such as thatch grass, papyrus and reeds

may probably have minimal detrimental impact if it is regulated. However, tree cutting for poles,

fire wood, charcoal making and timber exploitation may significantly change habitat conditions

and thus cover pattern in most areas due to the commercialization of the products. There is

currently high demand for wood fuel and thatch grass in most urban areas which increases

vegetation clearance. Habitat loss coupled with burning facilitates hunting especially during dry

seasons when plant biomass was reduced in wetlands. Extensive burning of the wetland was

reported in Mayanja site Camille and Boyce (2017) and this type of habitat destruction paves way

for establishing farm lands and facilitates hunting as hiding sites for sitatunga are destroyed leaving

them vulnerable to hunters. This types of burning is very common in wetland habitats around

Uganda. One incidence of active fire burning event was recorded during the time this study at

Katonga WR site although the extent of damages was not measured. In general terms fire was

observed to destroy large area of papyrus habitat. The open or cleared habitat deprives sitatunga

of shelter and thus exposing them to human predators and other natural predators. The

increasing demand for food and other materials, in combination with droughts that make

upland agriculture more risky, has intensified farming in wetlands (Wood and van Halsema,

2008; Rebelo et al., 2010). Increasingly, wetlands are reclaimed permanently for large scale

farming, often through corporate or government activity e.g. in the Yala wetland, Kenya

(Kinaro, 2008) and in Uganda where swamp rice variety is being promoted. Sitatunga is adapted

to survive in swamp vegetation conditions only and any artificial reduction in water flows may

result in reduction in sitatunga numbers (Games, 1983). The Uganda govrenment proposal to

increase food production through use water for crop production and the challenge of expanding

swamp rice growing are somne of the biggest challenges to sitaunga habitat throuhout Uganda.

Page 60: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

50

Suitable wetland habitats for survival of sitatunga are currently disappearing rapidly due to

drainage and manipulation of water table, competition with domestic animals during period of

drought and the consequent effects of poaching (Brudels-Jamar et al. 1997). In the study sites there

were incidences of annexing of wetlands for expansion of agricultural crop and livestock

production which is currently increasing due to the challenges of climate change across Uganda.

This results in increased degradation and destruction of natural wetland habitats and increased

competition of livestock with sitatunga for water, grazing and other natural resources. Moreover

in addition to fragmentation of habitat and thus isolation of populations into small sizes makes the

future of the sitatunga populations to become very precarious. At the moment there are few

relatively less disturbed wetlands e.g. in Mayanja, Nakaseke, Kafu and Nakasongola areas but this

may change in the next 20-50 years if no action is taken to secure continuation of the current status

quo. Thus the future of sitatunga depends on the continuing existence of large and continuous

stretches of wetland. In spite of Uganda being one of the many countries that ratified the Ramsar

Convention, wetlands in Uganda continue to be under threat of being drained and reclaimed

(Verhoeven and Setter, 2009). The wide spread distribution of populations of sitatunga across

Uganda which are wetland- dependent may crash as the remaining population may occur only in

those fragments of wetlands which survive as part of the protected areas within a human-

dominated landscape e.g. in Katonga wildlife reserve.

This study identified that wildlife hunting was still persisting in all parts of study and possibly

throughout Uganda despite banning of hunting in 1970s. The magnitude of poaching recorded

from this study may be low and tolerable in case the suitable habitat is still sufficient. According

to Timberlake and Childes (2004) sitatunga copes well with high hunting pressure in much of its

range, but is most threatened by drying out of its aquatic habitat caused by changes in hydrology

(Ross et al., 1998). Kingdon (1997) similarly reported that sitatunga can persist in areas with high

human population provided their suitable habitat is available. In Uganda subsistence hunting in

areas with very low human densities may have little impact on sitatunga populations, but this can

change rapidly as human populations increase. A studies in delta area near Murchison falls N.P

(Ocen & Andama 2002) suggest that the communities do not invest a lot in sitatunga hunting

because it is difficult to hunt unlike other antelope species which are much easier to locate. This

suggests that hunting may not be a big threat to sitatunga within their areas of distribution but

habitat loss is the main challenge. Observations in this study suggests that during the dry season

Page 61: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

51

wetland vegetation and riverine forest act as islands of green vegetation for the survival of wide

variety of animals including Sitatunga.

Habitat fragmentation is also a threat to the future persistence of sitatunga as there is an ever-

increasing loss of wetlands throughout their range which are cut off former routes of dispersal and

many sitatunga populations become isolated (IUCN, 2016). Sitatunga are reported to be vulnerable

to long-term changes in water level because it alters vegetation structure, which in turn largely

determines their distribution and abundance. Habitat fragmentation and fluctuations in water levels

make them more vulnerable to predation and hunting in many parts of its range (May & Lindholm

2013). There is need for wildlife corridors to enhance species survival through increasing food

sources, decreasing the chance of predation, providing suitable habitat, and provides opportunity

for reconnecting isolated populations (DFW 2004). Swamps are also extremely vulnerable to fire

for example vast areas of Bangweulu and Busanga are burnt each year (May & Lindholm 2013).

Swamp/wetland burning is common in Uganda for example during the time when Camille was

undertaking her study the vast areas of Mayanja swamp was completely burnt (Camille and Boyce,

2016). During this study the team also noted burning of swamp habitat in Katonga WR.

Nonetheless, the Sitatunga shows a remarkable ability to survive near human habitation, provided

suitable habitat remains.

Human activities around Lake Vitoria Basin (LVB) which hosts large wetlands system have

accelerated and the rate of ecological change is increased which threats conservation of wetland

dependent organisms and the ecosystems services they provide. About 80% of the human

population living in the LVB derives its livelihoods from subsistence agriculture (GIWA, 2006).

Thus, agriculture, which is intensifying on most catchments, will continue to have significant

impacts on the environment and especially the wetland ecosystems. The main driver of changes in

Lake Victoria ecosystem is human population pressure, especially its increasing size, rapid growth

rate and increasing urbanization and immigration. In the upper reaches of many rivers, the main

threats to wetlands are reclamation for agriculture, overgrazing, human settlement and

encroachment, siltation, pollution (mainly from agriculture and industrial sources), introduction of

exotic species such as blue gum trees (Eucalyptus spp.) and overharvesting of water dependent

plants. The weak legal and institutional frameworks have contributed towards unfavorable

environment for wetland conservation and sustainable use in Uganda. To mitigate wetland

degradation one of the government’s approaches to curb underlying and proximate national

Page 62: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

environmental stresses on biodiversity has been through the delimitation and implementation of

in-situ protection strategies in protected areas (Tchigio 2007). The signing of the Ramsar

convention is one of the many ongoing strategies established to protect unique biodiversity

particularly the wetland biodiversity including sitatunga which is specialized for wetland

environment. Nonetheless, diverse land use and fragmentation from illegal hunting grazing,

agricultural extension, gathering for subsistence and complete conversion of areas to meet

settlement and other developmental needs, such as irrigation crop framing, livestock farming and

hydroelectricity dam construction are evident in the Ugandan wetland systems which negatively

affect populations of swam dwelling wildlife species.

5.1.3 Opportunities for conservation of sitatunga

In order to ensure the long-term conservation of sitatunga it is important to maintain as many viable

populations in different habitats which are connected as possible. For this to succeed

environmental and biodiversity conservation strategies need to be integrated with human

development needs (East, 1990). Conservation of sitatunga requires conservation of as many

wetland habitats with viable sitatunga populations as possible to support and enable healthy

populations to persist (East, 1999). This includes a range of wetland-use options, from strictly

protected national parks and reserves where consumptive use of wildlife is not permitted, to areas

of natural habitat which are managed for sustainable utilization, e.g., through trophy and/or meat

hunting, as part of multiple resource use systems. Establishment of national parks, wildlife reserves

and other categories of protected areas of natural habitat has been a major component of wildlife

conservation in both colonial and post-independence Africa and a network of protected areas

extends across the continent (IUCN, 1998). UWA manages 10 national parks 12 wildlife reserves,

5 community wildlife management areas and 13 wildlife sanctuaries which constitute protected

areas some of which are important in providing suitable habitats for conservation of sitatunga.

Few of the protected areas such as Murchison fall National Park, Lake Mburo N.P, Bwindi

Impenetrable National Park, Ajai wildlife reserve Katonga wildlife reserve and Semliki among

other have sitatunga. It is however, noted that much of the suitable habitats for sitatunga occur

outside the protected areas and are in public or private land which becomes constraint to their

conservation. This scenario calls for development of partnership with the privet business, persons

and adjacent communities to promote sustainable use of the wildlife habitats and resources

including sitatunga. Promoting incentives is key because wildlife conservation is unlikely to

succeed unless the economic value of biodiversity is recognized and the value of wildlife

Page 63: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

53

utilization exceeds that of alternative land-use options (McNeely 1993; Lane et al., 1994; Adams

& Thomas, 1996). This calls for integrated strategies that will involve community wise use of

wetland resources, promoting community tourism and spots/trophy hunting opportunists among

others. For the option of promoting sport hunting the advantage is that Sitatunga is one of the

highly rated antelope species by the professional hunters due to its significance as a trophy animal

(Lindsey et al., 2006). This could provide the needed economic incentive for the conservation of

the wildlife species and their habitats (IUCN/SSC, 2016).

Based on high trophy value, sitatunga has the potential to generate funds for conservation work of

the species and its habitat. Trophy hunting can play a key role in conservation of species and

habitats, especially in non-protected areas which are not frequented by tourists. Sport hunting is

one of the ways the local communities benefit from the utilization of wildlife. Hunting revenue

can enhance economic development in the local area (WWF, 1997) and this can stimulates

conservation of the sitatunga habitat. To promote conservation of sitatunga it is important that

more wetland areas with viable populations of sitatunga be identified and brought on board of for

initiating and promoting sport hunting as a strategy for promoting conservation of the species.

5.1.4 Monitoring for healthy populations of Sitatunga

Uganda is signatory to Convention on Biological Diversity (CBD) and as such is required to

inventory and monitor status of biodiversity in the country. Regular monitoring of species’

occurrences in a given habitat/site is a necessary component of biodiversity monitoring.

Continuous monitoring of wildlife numbers is essential in order to detect trends so that we can re-

adjust our earlier management decisions. Having information about wildlife numbers, rainfall

patterns and fire outbreaks to help us understand why changes in the wildlife population are taking

place and this enables wildlife managers to maximize their production and revenue without

destroying the wildlife resource (WWF, 1999). According to Sparrow et al. (1994) no matter how

well documented population trends in a single taxonomic group such as butterflies are, they are

likely to provide only a partial picture of overall biological diversity. Long-term monitoring is

most effective when they include diverse taxa and accompanied by research into abiotic factors

such as macro and microclimate and habitat condition. A focused, multidisciplinary approach to

monitoring offers the best opportunity for obtaining biological information that is truly

useful in making informed management decisions . The communities in all study sites

demonstrated good knowledge of sitatunga ecology and behaviour which was correlated closely

Page 64: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

54

with information reported in the literature. The community knowledge on the ecology of sitatunga

suggests that they can play significant role in conservation of natural resource. The community

knowledge on the sites can be used for monitoring the populations and challenges facing sitatunga

conservation in wetlands. The community can therefore be incorporated as part of the monitoring

team for this purpose. Benefits of involving communities been reported in Mabamba wetland

Ramsar site in southern Uganda (Nature Uganda, 2009) where communities are key protectors of

the wildlife species.

This preliminary study provided results that can be used as a technical baseline for establishing a

sitatunga monitoring programme in the wetland systems. Sampling frequency should be

determined by monitoring needs, logistic constraints and seasonal changes.

Regular monitoring of sitatunga can be done regularly as follows;

(i) Transect to runs through representative habitats to document large mammals focusing on

sitatunga, their use of the habitat e.g. feeding signs, dung pellets, track etc. to give insight

into indices of abundance and population trends while incorporating other wildlife species.

(ii) Similar sites including protected areas should be included to enhance comparisons.

(iii)Sites should be surveyed at least every 3-5 years depending on logistics;

(iv) The trophy quality measurements data and study reports can also be used to indicate that

the use of hunting indices over a long time. Consistency in trophy quality is vital indicator

of the status of wildlife population health and this approach is an effective way of setting

and monitoring Sitatunga quotas through an adaptive management approach.

5.2 Conclusions

The findings of this study indicate that sitatunga still occurs in relatively viable populations in the

study sites. The study also demonstrated the importance of sustainable use of wetlands as critical

for conservation of sitatunga in the country. The main threat that significantly impacts on

conservation of sitatunga include habitat loss due to human activities ranging from need for land

for farming due to climate change impacts, need to feed increasing human populations and

urbanization among others. Five categories of human threats were recorded from this study

and the intensity of each of these categories also varied in different wetland sites. The

abundance and distribution of sitatunga varied between habitats as a result of the presence of

human threat indicators as shown in this study. Sitatunga is an antelope species which is dependent

on wetland habitat and any development which negatively affect wetland status negatively affect

the survival of the species. Areas with intensive human activity registered low abundance of

sitatunga. This calls for urgent actions to mitigate human induced wetland habitats degradation

which are not only the help in securing sitatunga conservation but also other wildlife and other

ecosystem service that accrues from the conservation of the wetlands.

5.3 Recommendations

To promote sustainable future for sitatunga in the wetland ecosystems the following actions are

recommended. The roles and responsibilities of different stakeholders and government units in the

implementation of the recommendations are shown in the appendix 3 and the Non detrimental

Findings for Sitatunga in the appendix 4.

(i) Take landscape based approach to conservation actions and activities, recognizing the

three major habitat functions (a) the wetland landscape which provides habitat to wider

ecosystem services to the community, (b) being habitats for sitatunga and other wildlife

species, and (c) humans use of wetland habitat for extractive and consumptive

resources to advance wetland management objectives.

(ii) Develop sensitization and awareness campaign programmes that might improve

networking and collaboration between stakeholders and possibly attract their

interest in the protection of the wealth of biodiversity in the wetland ecosystem. In

this regard, sensitization and awareness campaigns addressing the wetland

management policies, risks and benefits that may accrue from successful participation

and conservation are recommended.

(iii) Develop integrated approach to conservation of wetland ecosystem through; Investing

in alternative livelihoods opportunities based on sustainable use of wildlife resources

and its habits such as bee keeping, monitored resources extraction. This would be

alongside sport hunting or ranching of wildlife for meat to provide financial incentives

for the local community to maintain wildlife in these corridor areas. The adjacent

communities in these wetland systems need to be sensitized on how to sustainably use

resources in their area while conserving them.

(iv) Continuous monitoring of sitatunga population and other wildlife species in the

wetland for remedial conservation action is proposed. In this regard, both scientific

and integrated (including stakeholders) long-term ecological monitoring programs

are suggested. This can be done through establishing a wildlife population and habitat

monitoring system with incorporation of community conservation initiative

programmes in wetland. Scientific monitoring of sitatunga and large mammal

population on the transects within wetlands that were surveyed during this study in the

study sites. Additional monitoring is proposed especially in Ssese islands which

contains endemic island sitatunga subspecies is recommended. Incorporate community

in the monitoring of sitatunga and wetland health for wider benefit such as ecosystem

service and conservation of sitatunga.

(v) Due to the increasing human pressure on wetland, there is need to demarcate wetland

boundaries to reduce encroachments. It is also important to ensuring connectivity

between different wetland systems through creating corridors to links two or more

larger wetlands habitats is vital to facilitate dispersal or allow undisturbed movement

of sitatunga within different populations/sites to avoid potential challenges of

inbreeding and promote healthy and viable populations.

Page 66: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

56

(vi) Strengthen institutions responsible for wetland management at local government levels.

There is need to sensitize, train and strengthen local government at district and lower

levels (environment committee) to management the wetlands sustainably.

(vii) Initiate collaborative management of wildlife on private/public land for management

of wetland habitats. This is consistent with the Uganda Wildlife Act (2000) and the

Local Government Act (1997) and other laws and guidelines that may supplement

implementation of such imitative.

(viii) Develop Conservation Actions and species management plan for Sitatunga. This will

help in regulating and management of harvest and Trade in the species by the local

community and general public.

(ix) Development of enabling policy framework for wetland management, including:

f. Design and implement Ramsar sites and Framework wetland management plans.

g. Design and implementation of Ramsar site wetland research, eco-tourism and

education centers.

h. Design and implement District wetland action plans, with biodiversity and carbon

sink potential.

i. Promote wetlands law enforcement and governance.

j. Restore, regenerate, restock and gazette degraded wetlands in urban areas so as to

conserve biodiversity and promote increased ecosystem serves provision.

(xiv) Create an Island National Park in Lake Victoria Islands with Island Sitatunga

(T.s.sylvestris) as a Flagship Species for promoting Tourism in the Ssese Island. It has been

identified as potential endemic in Africa due to restricted occurrence in Ssese Island.

(xv) To institute byelaws on sustainable use of wetland and to ban burning of the swamps

/wetlands which are the habitats for sitatunga.

Non-detrimental finding for Sitatunga Tragelaphus spekii (Speke, 1863)

Summary of the NDF findings

Tragelaphus spekii (Speke1863) (Sitatunga) is currently included on IUCN Conservation Status

of least concern category (IUCN SSC Antelope Specialist Group, 2016). This document

summarizes the details of a non-detrimental finding (NDF) assessment for Tragelaphus spekii and

is based on the best available information as current as of October 2018. The report is further

strengthened by an expert consultation and the report of a scientific research commissioned by

UWA to determine the population, distribution and conservation status of Sitatunga (Tragelaphus

spekii) (Sclater) in selected wetlands in Uganda and data published in the refereed scientific

literature.

Sitatunga are long-lived with high reproductive rates of 80-100% in adult ewes and up to 45% of

ewes can reproduce twice a year (Furstenburg, 2018). Reproduction in Sitatunga is generally

continuous and not synchronized. The young Sitatunga have a survival rate of up to 80% before

weaning. Adult life expectancy in females averages 16 years while males reach approximately

10 years of age. Sitatunga are restricted to wetlands with permanent water source. Sitatunga are

semi-aquatic and their key habitats are marshes, swamps and floodplains bordering lakes and rivers

with permanent water source and an evergreen vegetation cover. This habitat is mostly restricted

to tropical and subtropical regions between 13°N around Lake Chad and 20°S, and from the

western coastline of Africa, eastwards to 35°E (May and Lindholm, 2013). In Uganda the species

is restricted to swamps with dense stands of papyrus Cyperus papyrus, reed beds of Phragmites

mauritianus and Echinochloa sp and beds of bulrush Typha sp bordered by an ecotone of terrestrial

thicket or woodland which are common along permanent rivers and lakes throughout the country.

Habitats with shrubby growth, herbs, sedges, tall grasses that border waterways are favoured due

to availability of lush herbage. Sitatunga enter forest clearings, gallery forests and forest islands

in savannahs if permanent and open water is present. Sitatunga also use wetland edges as well as

natural openings in the forest during the dark hours around sunrise and sunset (Flack, 2015,

Gessner et al. 2014) which expands its habitat ranges (Andama, 2019). They are selective mixed

feeders taking a range of grasses, sedges and browse (May and Lindholm, 2013). Information

presented in Delany and Happold (1979) and Kingdon (1982) indicate that Sitatunga prefers

to browse in low-growing thicket in and around marshy areas, as well as entering deeper water

to consume vegetation. Owen (1970) details foraging patterns with Sitatunga consuming a

wide variety of wetland plants, and again, Kingdon’s (1982) review of Sitatunga grazing

behaviour in wetland areas indicates that the animal regularly leaves resting areas of dense

cover to forage on new-growth grass. In areas surrounded with farm lands Sitatunga was

reported to graze on crops e.g. Zea mays L. (Ndawula, et al., 2011). Sitatunga inhabits

hydromorphic forests, swamps, and marshes; they enter forest clearings, gallery forests, and forest

islands in savannahs when permanent pools of water are present (Owen, 1970; Manning, 1983;

Starin, 2000). Sitatunga mainly feeds at the wetland edge habitat where most of its food was

located.

. Like most traglephini genus, Sitatunga are relatively poor dispersers and the degree of

connectivity between populations, within and outside of Uganda is unknown. Sitatunga is sensitive

to human disturbance and have been eradicated from some historic sites of its occurrence in Africa

such as Niger and Togo. It has recently been confirmed as still surviving in Ghana (May &

Lindholm, 2013). This is because Sitatunga is among antelope species which is dependent on

floodplain and wetland habitats for its survival. Thus any attempts to drain water and change the

natural habitat significantly reduces or eliminates the species in such areas. Sinibald et al. (2004)

suggested that natural vegetation such as papyrus was important for the survival of sitatunga and

the dependence of the species on papyrus as habitat could have been responsible for its extirpation

in some areas in Rwanda as was resported by Ndimukaga (2009) and and Kanyamibwa et

al.(2013). In this case the wetland habitat was affacted by drainage for hydropower, agriculture

and over exploitation of non timber wetland forest products which resulted in permanent loss of

the sitatunga habitat. Similarly, Nsabagasani et al. (2008) reported in Akanyaru wetlands of

Rwanda that human activities that destroyed wetland habitat led to the disappearance of

Sitatunga, resulting in their local extinctions.

The greatest enemies of Sitatunga are Nile crocodiles (Crocodylus niloticus), leopard (Panthera

pardus), python, hyena, lion, feral dogs and human as source of wild meat for man (Cott, 1961;

Henschel et al., 2005; Furstenburg, 2009 ).

Uganda’s 1995 Constitution provides for wildlife conservation as well as biodiversity and the

natural environment; thus creating an enabling environment for policy formulation, planning and

programme development. Under Objective XIII, the Constitution obliges the state to protect

important natural resources, and also provides for creation and development of Parks, Reserves,

and recreation areas (. Out of a total surface area of Uganda (241,551sqkm (both land and water),

25,981.57sqkm (10%) is gazetted as wildlife conservation areas, 24% is gazetted as forest reserves

and 13% is wetlands (. Uganda has 10 National Parks, 12 Wildlife Reserves, 10 wildlife

sanctuaries, 5 community wildlife areas 506 central forest reserves and 191 local forest reserves.

It is however estimated that over 50% of Uganda’s wildlife resources still remain outside

designated protected areas, mostly on privately owned land; and is of most urgent concern for

protection and development.

Uganda’s wetlands cover about, 29,000 sq. km, about 13% of the total area of the country which

is ideally suitable Sitatunga habitat. However, much of the total area is currently highly fragmented

due to agricultural expansions and developments, human settlement and human encroachment

among other human induced developments. Today Sitatunga are mainly found in the remote

wetlands far from urban setting and human developments. The main challenge to Sitatunga

conservation is the fact that most wetlands in Uganda occur outside of protected areas. The habitat

related threats to wetland biodiversity in general within Uganda include, unsustainable resource

harvesting (Pypyrus and other grasess) habitat loss through agricultural conversion, industrial

development and burning (NEMA (2009). There is also inadequate enforcement of legislation,

regulations and compliance in wetlands use as stipulated in the wetland act. As lready noted the

negative impacts associated with wetland drainage include reduced and/or loss of biodiversity such

as the population reduction of grey Crowned Cranes (Uganda’s symbol) and Sitatunga (Pomeroy

et al., 2017). The fragile wetlands are under threat from drainage, overgrazing, sand harvestng,

overharvestng of plants and many other human actvites. Other threats include invasive species

such as Elephant grass, Mauritus thorn and Lantana camara, three plant species that grow

rapidly in wetlands and suppress wetland plants (Wanjala, 2014). .

Page 82: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

Conservation approach historically promoted preservation rather than utilization and community

Participation (MTWA, 2014). It was not until 1994 that the Wildlife Policy for Uganda gave

recognition to community participation in wildlife management. The paradigm shift to

involvement of local people in conservation has created opportunities for communities to directly

engage and benefit from wildlife conservation. According to estimates by the Uganda Wildlife

Authority (UWA 2005) over 50 % of wildlife lives and/or feeds outside protected areas. This

exposes them to the risk of illegal hunting, and intensifies human-wildlife conflicts. In order to

address these issues, the government extended conservation efforts outside protected areas (PAs),

which led to the enactment of the Wildlife User Rights (WURs) by UWA in 2000 (Ayorekire et

al., 2011). One of the key elements of these WURs is the reintroduction of sport hunting or trophy

hunting. In 2001 sport hunting was reintroduced in Uganda around Lake Mburo National Park,

and in 2008 at Kabwoya and Kaiso-Tonya Game Management Area, to derive economic benefits

for communities and thus reduce human–wildlife conflict and change communities’ attitudes

towards wildlife (Ochieng et al., 2017). Nationally, monitoring of trophy hunting of Sitatunga is

limited to records of the numbers of removed/allocated per quota of Sitatunga each year in different

concession sites. While other forms of harvest are illegal and therefore unregulated. There is no

monitoring and thus reliable estimates of the extent of illegal off-take of Sitatunga in Uganda. As

such it is not possible to speculate if levels of illegal off-take exceed the levels of legal off-take

through trophy hunting. There are is effective incentives for habitat conservation arising from the

harvest of Sitatunga since there is a report indicating that trophy hunting can foster community

tolerance towards the species and its habitat. At the moment a relatively smaller proportion of the

species are included in areas allocated for concession. There are many habitats in Uganda which

are found outside concession areas and protected areas where wild mammals occur. The Sitatunga

populations in unprotected areas and area with no concession probably continue to be reduced by

illegal hunting since there are no incentive for the community in such sites to conserve the habitat

and the species. The imposition of a CITES quota also limits the numbers of Sitatunga trophy

hunted each year. Additionally there are restrictions on the sex, age/size of Sitatunga that can be

hunted. Only adult males are allowed to be removed. Research has shown that polygynous

traglephini such as Sitatunga are resilient to disturbance if the prime reproductive female life-stage

remains intact. There is need to conduct population viability analysis for Ugandan Sitatunga

population to assess the level of risk of females being were included on trophy quota.

Any action plans to conserve wetland habitats equally benefits Sitatunga conservation. The Ramsar

Convention of 1971 was the first international treaty that promotes conservation and wise use of

wetlands on a global scale (Farrier et al., 2000). Uganda is a signatory to Ramsar convention and

joined the Convention in 1988 and now has 11 Ramsar sites covering a surface area of 354,803

hectares. The National Policy for the Conservation and Management of Wetland Resources

(MWE, 1995). The policy aims at curtailing the rampant loss of wetland resources and ensuring

that benefits from wetlands are sustainable and equitably distributed to all people of Uganda. In

this respect, therefore, the wetlands policy calls for: (i) no drainage of wetlands unless more

important environmental management , (ii) requirements supersede, (iii) sustainable use to ensure

that benefits of wetlands are maintained for the foreseeable future; (iv) environmentally sound

management of wetlands to ensure that other aspects of the environment are not adversely affected;

(v) equitable distribution of wetland benefits; and (vi) the application of environmental impact

assessment procedures on all activities to be carried out in a wetland to ensure that wetland

development is well planned and managed. In order to put the policy goals and objectives into

Page 83: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

73

practice and to provide a legal framework for implementing the policy, wetland related issues have

been adequately incorporated into the National Environmental Statute 1995. One of the important

Regulation is the National Environment (Wetlands; River Banks and Lake Shores Management)

Regulations, 2000 which provide for the conservation and wise use of wetlands and their resources

in Uganda and this was strengthened in the National Environment Bill 2017 (GoU, 2017). Based

on the Ramsar convention several of the wetland sites for example Lake Nabugabo wetlands

system Ramsar site Management Plan (2017- 2027). Uganda has also developed an Action Plan

for cranes, which proposes that more effort be made to reduce or even prevent illegal draining or

conversion of the seasonal swamps. These and other measures are very elaborate to promote

sustainable use of wetland habitats and resource which are directly linked to conservations of

sitatunga. Despite the elaborate framework, wetlands have declined from an estimated 13% of the

total land area in 1994 to 10.9% in 2008 (Nsubuga et al., 2014). Out of a population of 34.6 million,

80% of Ugandans are involved in agriculture and 69% rely on subsistence farming and are heavily

dependent on wetlands (UBoS, 2016). This means the trend in wetland degradation will continue

if no drastic measure are taken to halt the decline. As a result of the increased use of wetland

areas, there has been an increase in the frequency of vegetation clearance, draining and

diversion of water flow, crop cultivation, overgrazing, sand mining and exposing the soil surface

to erosion (MWE, 2013). All these directly or indirectly affect the survival of sitatunga and its

conservation status.

Radar chart summarizing the non-detrimental finding assessment for Tragelaphus spekii

(Sitatunga) (figure1) in accordance with the CITE NDF checklist. The non-detriment finding

assessment (Figure 1) demonstrates that hunting trophies at present does not poses risk to the

survival of this species in Uganda (Figure 2). This is mostly due to the indication that the local

communities and land owners and the local district are building positive attitudes towards benefit

that accrues form the trophy harvest practices which have recently been introduced in the country.

However there is lack of reliable monitoring of Sitatunga populations especially outside the

concession areas. There is need to develop a monitoring frameworks for Sitatunga population

monitoring outside the community concessions areas and the protected areas. This will facilitate

adaptive management of the harvest of the species, as well as provide insight on the effects of the

illegal off-take of Sitatunga.

The main human threats that negatively impacts on conservation of sitatunga included habitat

loss due to human activities, ranging from increased need for wetland for farming due to climate

change impacts, expansion of agricultural land in wetlands to produce food to feed the increasing

human populations. Areas with intensive human activity held low abundance of sitatunga

population. For these reasons, it is recommended to implement conservation actions and activities

focusing on the following actions:

(x) Take landscape based approach to conservation actions and activities, recognizing the

three major habitat functions (a) the wetland landscape which provides habitat to wider

ecosystem services to the community, (b) being habitats for sitatunga and other wildlife

species, and (c) humans use of wetland habitat for extractive and consumptive

resources to advance wetland management objectives.

Page 84: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

74

(xi) Develop sensitization and awareness campaign programmes that might improve

networking and collaboration between stakeholders and possibly attract their

interest in the protection of the wealth of biodiversity in the wetland ecosystem. In

this regard, sensitization and awareness campaigns addressing the wetland

management policies, risks and benefits that may accrue from successful participation

and conservation are recommended.

(xii) Develop integrated approach to conservation of wetland ecosystem through; Investing

in alternative livelihoods opportunities based on sustainable use of wildlife resources

and its habits such as bee keeping, monitored resources extraction. This would be

alongside sport hunting or ranching of wildlife for meat to provide financial incentives

for the local community to maintain wildlife in these corridor areas. The adjacent

communities in these wetland systems need to be sensitized on how to sustainably use

resources in their area while conserving them.

(xiii) Continuous monitoring of sitatunga population and other wildlife species in the

wetland for remedial conservation action is proposed. In this regard, both scientific

and integrated (including stakeholders) long-term ecological monitoring programs

are suggested. This can be done through establishing a wildlife population and habitat

monitoring system with incorporation of community conservation initiative

programmes in wetland. Scientific monitoring of sitatunga and large mammal

population on the transects within wetlands that were surveyed during this study in the

study sites.

(xiv) Due to the increasing human pressure on wetland, there is need to demarcate wetland

boundaries to reduce encroachments. It is also important to ensuring connectivity

between different wetland systems through creating corridors to links two or more

larger wetlands habitats is vital to facilitate dispersal or allow undisturbed movement

of sitatunga within different populations/sites to avoid potential challenges of

inbreeding and promote healthy and viable populations.

(xv) Strengthen institutions responsible for wetland management at local government levels.

There is need to sensitize, train and strengthen local government at district and lower

levels (environment committee) to management the wetlands sustainably.

(xvi) Initiate collaborative management of wildlife on private/public land for management

of wetland habitats. This is consistent with the Uganda Wildlife Act (2000) and the

Local Government Act (1997) and other laws and guidelines that may supplement

implementation of such imitative.

(xvii) Develop Conservation Actions and species management plan for Sitatunga. This will

help in regulating and management of harvest and Trade in the species by the local

community and general public.

(xviii) Development of enabling policy framework for wetland management, including:

k. Design and implement Ramsar sites and Framework wetland management plans.

l. Design and implementation of Ramsar site wetland research, eco-tourism and

education centers.

n. Promote wetlands law enforcement and governance.

o. Restore, regenerate, restock and gazette degraded wetlands in urban areas so as to

(xvi) Create an Island National Park in Lake Victoria Islands with Island Sitatunga

(T.s.sylvestris) as a Flagship Species for promoting Tourism in the Ssese Island. It has been

identified as potential endemic in Africa due to restricted occurrence in Ssese Island.

(xvii) To institute byelaws on sustainable use of wetland and to ban burning of the swamps

/wetlands which are the habitats for sitatunga.

Sitatunga of both sexes reach sexual maturity at 18 -24 months (Furstenburg 2018). They start

breeding at 2-2.5 years for ewes and 3-3.5 years for bulls. First Lamb is born at the age of 2.5

years and after gestation period of 165 days. Breeding is throughout the year. Lambing interval

of 5.5 -9 months and any time of the year. The young reach independence at 4 -6 months. Life

Sitatunga are semi-aquatic and spend their entire lives in the close vicinity of open water

habitats, especially of marshes, swamps and floodplains bordering lakes and rivers with

permanent water. Sitatunga usually avoid open water devoid of vegetation. They are selective

mixed feeders taking a range of grasses, sedges and browse (May and Lindholm 2013). The

most essential requirement is permanent, open water and an evergreen vegetation cover for

feeding and camouflage. The species is thus Water dependent. This habitat is mostly restricted

to tropical and subtropical regions between 13°N around Lake Chad and 20°S, and from the

western coastline of Africa, eastwards to 35°E. The optimal habitat is swamp with a water depth

of up to 1 m with dense stands of papyrus Cyperus papyrus, reed beds of Phragmites

mauritianus and Echinochloa sp and beds of bulrush Typha sp bordered by an ecotone of

terrestrial thicket or woodland.

3. Dispersal efficiency: How

Uncertain 5

Sitatunga is rather moderate disperser and within the optimum habitat. Immigrations and

emigrations do occur over time (Magliocca, et al, 2002). In the long term, avoidance of

inbreeding could be the ultimate factor that would induce young females to emigrate (e.g.,

Harcourt 1978; Rutberg and Keiper1993; Monard and Duncan 1996). The main challenge to

dispersal of Sitatunga is the ever-increasing loss of wetlands throughout their range which cuts

off their former routes of dispersal and as such many populations are becoming isolated. Genetic

data are required to further assess connectivity between different Sitatunga populations in

Uganda.

Loss of habitat is the main threat to the future persistence of Sitatunga. Cultivation in wetland

in time of dry season (during food stress) is on increase especially in eastern and central

Uganda and is the biggest threat to the Sitatunga system. Most of farmers who cultivate at the

wetland burn their lands. They also engage in draining excess water by digging trenches

thus destroying the habitat and leading to loss of biodiversity. The use of fertilizer and

chemicals cause water pollution and endanger the species within the wetland and especially

Page 88: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

78

the Sitatunga Animal. Another increasing threat is planting of Eucalyptus trees in the

wetland which lowers the water table. The growing urban market opportunities do also

encourage wetland drainage for vegetation growing. Wetlands are upheld highly in the

community as an important pasture during dry season and this communal grazing for

animals. Encroachment of the wetland by brick makers threaten wetland area, plants and

wildlife which are of social-economic importance to the riparian communities.

Uncertain 5

The potential habitat for Sitatunga, the wetland covered by wetlands is estimated to cover about

10.9% of Uganda’s total area (MWE, 2017), resulting about 30,000 km2 of the land surface

area. However, only a small area which are not yet degraded still provide suitable habitat for the

species. Acording to NEMA (2009) most wetlands in Uganda occur outside of protected areas.

The Protected Areas in Uganda where Sitatunga has been recorded include Murchison Falls

National Park (MFNP) (Andama and Ocen, 2002), Kibale NP, Lake Mburo NP and Katonga

Wildlife Reserve (WR) (Wilson, 1995), Semliki National Park, Ajai wildlife reserve and Pian-

Upe Wildlife Reserve and Ssese islands wildlife reserve (Ochieng et al., 2015).

The key threats to wetland biodiversity in Uganda include, unsustainable resource harvesting,

Habitat loss through agricultural conversion, industrial development and burning which reduces

national distribution pattern.

Precise estimates of the Uganda Sitatunga population has been done recently, In suitable habitats

Sitatunga densities of 55-200 animals per 100 ha optimal habitat have been reported, although

their long-term sustainability has not been established. A conservative population estimate of

4025 is estimated in the key concession areas. However, none of these estimates are not based

on rigorous population counts and do provide picture of a national population status.

79

Populations in large protected areas such as Murchison falls N.P, Katonga W.R, Ajai W.R

among others are probably stable. Sitatunga range has likely decreased in Kalangala following

instruction of commercial palm oil plantations. Observations suggest that there is currently more

encroachment of the Sitatunga habitat in most sites including Ssese Island. In Kyankwanzi,

Nakaseke and Kafu the livestock farmers seem to be more tolerant of Sitatunga. The rates of

illegal off-take due to poaching may not be high as the habitat is difficult to access and the

elusive behaviour of the species. Trophy outa hunting which is set is still at a sustainable level.

Reliable information on Sitatunga population sizes and trends at a national scale is based on

estimates. Recent rigorous population estimates was undertaken by Camille and Boyce (2017).

Detailed estimates of abundance are available for only a very small fraction of the population in

the four of the concession sites, A monitoring frameworks that is being developed still underway

Loss of habitat is the main threat to the future persistence of Sitatunga. Cultivation in wetland

in time of dry season (during food stress) is on increase especially in eastern and central

Uganda and is the biggest threat to the Sitatunga system. Most of farmers who cultivate at the

wetland burn their lands. Other key documented threats to Sitatunga populations in Uganda

include illegal hunting for meat .Habitat loss and fragmentation is also an increasing problem in

some parts of Uganda, due to the development of urban areas, and agriculture. In the central and

eastern Uganda, the loss of wilderness areas is resulting in reduced habitat for Sitatunga.

However, at this stage, the relative severity of threats is unknown, due mainly to lack of reliable

data on the extent of illegal off-take of Sitatunga in Uganda.

They also engage in draining excess water by digging trenches thus destroying the habitat

and leading to loss of biodiversity. Encroachment of the wetland by brick makers threaten

wetland area, plants and wildlife which are of social-economic importance to the riparian

communities. Fires are frequently and deliberately started by people throughout the wetlands

across Uganda on annual basis during dry season. I is aimed at (1) stimulate new growth for

livestock grazing (2) improve stands of reeds and thatching grass, (3) clear access routes through

the wetlands to fishing sites, and (4) clear agricultural land around the margins of the wetlands.

Therefore vast areas of wetlands are subjected to burning every year. The fire damage to their

habitat exposes them to predation by various animals and humans. Nonetheless, the Sitatunga

shows a remarkable ability to survive near human habitation, provided suitable habitat remains.

Little is known about the extent of illegal off-take and trade of Sitatunga and their body parts

in Uganda, although anecdotal information suggests it is small (particularly the illegal harvest

for meat). Traditional hunting is officially burned in Uganda although animals illegally hunted

are not recorded. Recent observation (per, communication Dr. Adoonia 2018) indicates that for

hunting blocks which are outside PAs sport hunting has generally assisted to reduce massive

illegal killing of wildlife. E.g. areas like Kafu Basin/rangeland.

Trophy hunting was introduced and Sitatunga is one of the favored animal species by the

concessionaires (UWA, 2018). The trophy hunting Quota is controlled by UWA on annual basis.

The quota was set largely based on available census estimates carried out in various sport

hunting areas. Traditional threshold of 2% of the species’ population was used in setting the

quota.

12. Management plan or

Equivalent: Is there a management

plan related to the harvest of the

species?

Approved and coordinated local and

national

management plans

Approved national/state/provincial

management

plan(s)

2

Approved local management plan 3

No approved plan: informal unplanned

management

4

Uncertain 5

There is no specific plan in relation to harvest of Sitatunga. However, there is a coordinated

national approach or holistic management plan for Sitatunga species through allocation for

various concession areas. This provides standardized guidelines for the management of the

species - particularly for managing trophy hunting and monitoring of the populations - is

required.

13. Aim of harvest regime in

management planning: What is

harvest aiming to achieve?

Generate conservation benefit 1

Population management/control 2

Maximize economic yield 3

Opportunistic, unselective harvest, or none 4

Uncertain 5

Trophy hunting is practiced to generate conservation benefits. As provided under Section 29 of

the Uganda Wildlife Act Cap. 200, UWA adopted wildlife use rights (Class A –E) as a tool of

sustainable management of wildlife outside protected areas. Sustainable extractive utilization of

wildlife can provide cultural, customary, and socio-economic benefits at the local, district and

national levels. Approx. US$750,000, US$ 390,000 and US$250,000 has been generated over

time by Community Wildlife Association, Land owners and local governments respectively

(UGX. 5 billion).

14. Quotas: Is the harvest based on

a system of quotas? Ongoing national quota: based on

biologically

derived local quotas

Ongoing quotas: “cautious” national or

local

2

Untried quota: recent and based on

biologically

derived local quotas

3

Market-driven quota(s), arbitrary quota(s),

or no

quotas

Uncertain 5

Recent research suggests hunting quotas in various concession areas is set precautionary and

based on population estimates which is within the 2 off take principal. In general the number

set for annual quotas are within the sustainable limit which is aimed at reducing illegal harvest

by land owners and community so that they received benefits from trophy and actively

participate in preventing illegal

Off-take.

Control of harvest

15. Harvesting in Protected

Areas: What percentage of the

legal national harvest occurs in

State-controlled Protected Areas?

High 1

Medium 2

Low 3

none 4

Uncertain 5

No trophy hunting or illegal off take of Sitatunga is allowed in state protected National parks.

Trophy hunting only allowed in three wildlife reserve areas of Katonga, Ajai and Karenga/Pian-

Upe. The rest of concession quota are located in the private, community hunting areas.

16. Harvesting in areas with

strong resource tenure or

ownership: What percentage of the

legal national harvest occurs outside

Protected Areas, in areas with strong

local control over resource use?

High 1

Medium 2

Low 3

none 4

Uncertain 5

Most trophy hunting of Sitatunga occurs on private land and community controlled areas.

17. Harvesting in areas with open

access: What percentage of the

legal national harvest occurs in areas

where there is no strong local

control, giving de facto or actual

open access?

None 1

Low 2

Medium 3

high 4

Uncertain 5

Most trophy hunting of Sitatunga occurs on communal lands and private farms in Uganda but

access is still generally controlled by communal authorities and Uganda wildlife authority.

18. Confidence in harvest

Management: Do budgetary and

other factors allow effective

implementation of management

plan(s) and harvest controls?

High confidence 1

Medium confidence 2

Low confidence 3

No confidence 4

Uncertain 5

UWA has the resources allocated to implement management of quotas for various concession

areas.

However, none of the districts is likely have the capacity to curb the illegal off take of Sitatunga

effectively.

Monitoring of harvest

Page 92: POPULATION, DISTRIBUTION AND CONSERVATION STATUS …

19. Methods used to monitor the

harvest: What is the principal

method used to monitor the effects

of the harvest?

Direct population estimates 1

Quantitative indices 2

Qualitative indices 3

National monitoring of exports 4

No monitoring or uncertain 5

The Department of Community conservation at UWA records the numbers of CITES export

permits allocated to, and the numbers of Sitatunga hunting trophies on annual basis. Record

keeping is generally consistent among the concessionaires and UWA on harvest. There is

however no district based monitoring framework to track leopard population trends. A

community based monitoring framework should be developed at district level to monitor legal

and illegal off takes.

20. Confidence in harvest

monitoring: Do budgetary and

other factors allow effective harvest

monitoring?

High confidence 1

Medium confidence 2

Low confidence 3

No confidence 4

Uncertain 5

Confidence in monitoring the impacts of legal Sitatunga off-take (trophy hunting) at a national

level is generally undertaken by UWA. Monitoring of illegal off-take of Sitatunga is poor or

non-existent.

Incentives and benefits from harvesting

21. Utilization compared to other

threats: What is the effect of the

harvest when taken together with the

major threat that has been identified

for this species?

Beneficial 1

neutral 2

Harmful 3

Highly negative 4

Uncertain 5

Evidence suggests that legal off-take of Sitatunga through trophy hunting is likely to offsets

illegal off-take, but more research is required. In general questionnaire data suggest that

landowners were more tolerant of wildlife if they received benefit financially from sport hunting

of the species.

22. Incentives for species

conservation: At the national level,

how much conservation benefit to

this species accrues from

harvesting?

High 1

Medium 2

low 3

None 4

Uncertain 5

Accordingly UWA records between 2008-2016 the sport hunting programme generated over

UGX 3.5bn for UWA and UGX 1,646,093,726= for the District Local Governments, Land

owners, Community Wildlife Associations. For the case of Uganda Wildlife Safaris ltd. over the

8 year period a total of 1174,016.7 US$ was generated which was distributed to various

stakeholders concerned with wildlife conservation. This is one of the first benefit accruing which

had never been before sport hunting was introduced in Uganda. Trophy hunting has the potential

to increase tolerance towards wildlife in general and conservation of Sitatunga habitats in

Uganda. Clearly, research is required to understand the complex relationship between trophy

hunting and tolerance of landowners towards wild animals in general.

23. Incentives for habitat

conservation: At the national

level, how much habitat

conservation benefit is derived from

harvesting

Uncertain 5

Sitatunga, on their own, have the potential to influence land-use decisions by landowners. At

national level there is legal protection of the wetlands and this can be implemented at local level

by the districts and local council environment committees.

Protection from harvest

24. Proportion strictly protected:

What percentage of the species

natural range or population is legally

excluded from harvest?

>15% 1

5-15% 2

<15% 3

None 4

Uncertain 5

Most of the wetlands occur outside protect areas in Uganda. And protected areas under the

jurisdiction of UWA where Sitatunga occurs are limited to Murchison Falls National Park

(MFNP) (Andama and Ocen, 2002), Kibale NP, Lake Mburo NP and Katonga Wildlife Reserve

(WR) (Wilson, 1995), Semliki National Park, Ajai wildlife reserve and Pian- Upe Wildlife

Reserve and these constitute long term refuge for the Sitatunga.

25. Effectiveness of strict

protection measures: Do

budgetary and other factors give

confidence in the effectiveness of

measures taken to afford strict

protection?

High confidence 1

Medium confidence 2

low confidence 3

No confidence 4

Uncertain 5

There is a medium confidence in the effectiveness of strict protection measures implemented.

Even though Sitatunga within some protected areas might be exposed to strong edge effects, the

cores of larger protected areas such as the delta area of Murchison fall Parks, Katonga W.R

likely constitute inviolate refuges for Sitatunga. The imposition of a CITES quota on the number

of trophies that can be exported limits the number of Sitatunga legally hunted in Uganda each

year. No trophy hunting are allowed within any of the National park areas except illegal hunting

in vast swamps that fall within local government jurisdiction..

26. Regulation of harvest effort:

How effective are any restrictions

on harvesting (such as age or size,

season or equipment) for preventing

overuse)?

Very effective 1

Effective 2

Ineffective 3

None 4

Uncertain 5

The numbers of Sitatunga trophy hunted in Uganda each year is regulated by UWA and ministry.

There is further restrictions on the age, sex or size of Sitatunga removed, where only adult males

are allowed to be killed (UWA). Illegal off take is typically indiscriminate and not documented

in the country. Research has shown that polygynous bovids such as Sitatunga are resilient to

disturbance if the prime reproductive female life stage remains intact (Ref). Since one male can

mate with numerous females, fewer males are required to maintain the same levels of

reproduction and yet the trophy hunters favor the males due to the antlers which is the main

trophy of interest.
