Foreword

The Convention on Biological Diversity (CBD),negotiated under the auspices of the UnitedNations Environment Programme (UNEP), wasadopted in 1992 and entered into force in 1993.Its aims are the conservation of biological diver-sity, the sustainable use of biological resources,and the fair and equitable sharing of benefitsarising from the use of genetic resources. One ofthe major challenges facing the Convention onBiological Diversity is the communication ofresearch results in a way that provides the policymakers, their advisors, the scientific communityand other stakeholders with helpful insights.

Major factors leading to biodiversity loss arehabitat loss and degradation, invasive alienspecies, overuse of resources and pollution. Dueto the complexity of these factors, variousapproaches and strategies are being used toreduce biodiversity loss. All, however, require thebest available scientific information that allowsthe development and implementation of soundmanagement strategies.

The goal of the CBD Technical PublicationsSeries is to contribute to the dissemination ofup-to-date and accurate information on selectedtopics that are important for the conservation ofbiological diversity, the sustainable use of itscomponents and the equitable sharing of its ben-efits. A large and growing body of evidence hasclearly established the need to disseminate syn-thesis publications relevant to CBD objectivesand selected reports presented at CBD meetings.

The Technical Publications Series

is intended to:

• Foster scientific and technical cooperation;

• Improve communication between theConvention and the scientific community;

• Increase awareness of current biodiversity-related problems and concerns; and

• Facilitate widespread and effective use ofthe growing body of scientific and technicalinformation on conserving and using bio-logical diversity.

The CBD Technical Publications Series comes ata time when the international communitythrough the Conference of the Parties to theConvention has committed itself to achievingtangible results in all aspects of the sustainablemanagement of biological diversity for socialand economic purposes. We therefore believethat this series will be useful to the broader sci-entific community and those concerned withbiodiversity management.

I am very pleased to make available to the scien-tific community and those actively involved inbiodiversity management the sixth publicationin the CBD Technical Series, addressingSustainable management of non-timber forestresources. It is my hope that this publication willbroaden our understanding of the complexity ofthe issue and at the same time facilitate theimplementation of remedial measures to reduceor halt biodiversity loss.

I wish to express my sincere gratitude to all thosewho have contributed in one way or another inthe preparation and production of this series.

Sustainable management of non-timber forest resources

Executive summary

If policy on sustainable management of non-timber forest resources (NTFR) is to be implemented suc-cessfully, then recognition that there is no "one size fits all" policy is essential. Policies and their imple-mentation practice have to be tailored to local ecological, economic, cultural and political circumstances.This complexity and the diversity of species used are added to by two other factors. Firstly, that the"catch-all" nature of the terms "non-timber forest resources" or "non-timber forest products" (NTFP),which refer to all natural resources from forests apart from sawn timber. Secondly, the fact that NTFRconservation and use sits at the confluence of at least probably more Articles of the CBD than probablyany other component of natural resource use.

In the past, plant and bush-meat use values to people have either been disregarded, or if taken intoaccount, then the emphasis has either been on the values of plants or wildlife, rather than both togeth-er. In southern African savannas where community-based natural resources management programmeshave been developed, the emphasis has been on wildlife rather than plants, fungi or edible insects. Intropical forests, the opposite has tended to be true, with plant products taken into calculations of forestvalue rather than animals. Whether NTFR or bush meat use is considered from the perspective of locallivelihoods or conservation, species loss through overexploitation benefits neither local people nor con-servation in the long term. When a conservation area becomes the focus of high impact harvesting, over-exploitation also undermines the primary goal of any protected area: the maintenance of habitat andspecies diversity. If even monitoring shows that forest or woodland cover are not decreasing, what is hap-pening beneath the canopy may be quite different: populations of high value, vulnerable plant and ani-mal species can be disappearing due to species specific overexploitation. This situation is rarely takeninto account in protected area management.

This review makes the following recommendations to the Subsidiary Body on Scientific, Technical andTechnological Advice:

• To achieve a balance between conservation and sustainable use of non-timber forest resources andanimals hunted for bush meat, there is a need to consolidate protected area networks and establishand maintain corridors (Article 8a);

• Ecosystem level planning and the management of harvested or hunted populations must take placethrough a process of consultation, which takes relevant scientific, local and indigenous knowledgeinto account. Ecosystem level and harvested/hunted population management plans need to bedeveloped with an understanding of the social, economic, ethical, religious and political factors thateither encourage resource conservation or lead to resource depletion. Development and implemen-tation of effective conservation and resource management plans may need legislative reform beforemanaged use of non-timber forest resources provides and incentive for conservation as a form ofland-use (Article 8k);

• Land-use planning and sitting of infrastructure (roads, new settlements) both need to take protect-ed areas, their adjacent conservancies or co-management areas and the requirements for maintain-ing viable populations of valued, but vulnerable species into account. Legislative change, technicalsupport and economic incentives for ecological restoration of wildlife corridors and for the controlof invasive plant and animal species may be necessary for maintenance or re-establishment of viablepopulations of indigenous plant and animal populations;

• A folk taxonomy initiative should therefore be formed as a separate, new component within the cur-rent Global Taxonomy Initiative, which has been established as a means of promoting taxonomy andtaxonomic tools for implementation of the Convention (Articles 7 & 12);

Sustainable management of non-timber forest resources

• Sustainable levels of harvest of popular, less resilient plant and animal species need to be establishedand monitored as part of an adaptive management process. This can be achieved through creativepartnerships between scientists and local resource-users and requires Technical co-operation(Articles 18 and 25c);

• Appropriate and economically viable monitoring systems should be developed and established atthe landscape level (remote sensing, aerial photograph analysis) and local level (indicator species)(Article 7);

• Integrate non-timber forest resources uses into forest inventory and management;

• Conservation through cultivation or farming of wildlife which is economically viable and on a suf-ficient scale to take the pressure off wild stocks;

• Ex situ conservation needs to be implemented for some high value, high vulnerability species(Article 9).

In summary, the complex, crosscutting characteristic of sustainable management of NTFR should notbeen seen as a problem. There is a great opportunity, given the political will, for implementation ofmeasures that can make a major contribution to the three main objectives in Article 1 of the CBD andto human welfare.

1. The broad terms "non-timber forestresources" (NTFR) or "non-timber forest prod-ucts" (NTFP) refer to natural resources collectedfrom forests apart from sawn timber. Wickens(1991), for example, considered non-timber for-est products to be "all the biological material(other than industrial round wood and derivedsawn timber, wood chips, wood-based panel andpulp) that may be extracted from natural ecosys-tems, managed plantations, etc. and be utilisedwithin the household, be marketed, or have social,cultural or religious significance". Chamberlain etal. (1998) provide a slightly more limited, yet stillbroad, definition: non-timber forest products areplants, parts of plants, fungi, and other biologicalmaterial that are harvested from within and on theedges of natural, manipulated or disturbed forests.According to Chamberlain et al. (1998) NTFPmay include fungi, moss, lichen, herbs, vines,shrubs, or trees. Many different parts are harvest-ed, including the roots, tubers, leaves, bark, twigsand branches, the fruit, sap and resin, as well asthe wood. In this document, the term ‘non-tim-ber forest resources’ is mostly used.

2. Sustainable management of NTFR sits at theconfluence of more Articles of the CBD thanprobably any other component of naturalresource use. A feature of sustainable manage-ment of NTFR is the high diversity of speciesused (Articles 5, 6 & 7), the local and indigenousknowledge linked to those uses (Article 15, 8j)and the varying tenure arrangements and eco-nomic incentives for conservation (Article 11).In addition, NTFR trade networks are oftencomplex, with serious impacts on species popu-lations (Articles 3, 5 and 11), requiring innova-tive assessment, monitoring and conservationmethods (Articles 7, 8, 9, 14, 16 & 18). NTFR useoccurs across a wide spectrum of biogeographic,ecological, economic, social and historical cir-cumstances across (and within) different conti-nents and vegetation types. Palms and bamboosfor example, are amongst the most useful tropi-cal plant resources, yet are poorly represented inAfrica (1.7% of palm species; 0.3% of bamboo

species) compared to other parts of the tropics.Differences across continents are equally evidentwhen it comes to animals used as bush-meat: theabsence of non-human primates in Australia, yetdiversity of marsupials; the high diversity ofbovid, ungulates and other large herbivores inAfrica; or the occurrence of pangolins in Africaand Asia, but not South America all clearly influ-ence the patterns of bush meat use. Policies andtheir implementation therefore have to be tai-lored to local circumstances. Simplistic, "one sizefits all" policies can do more harm than good andshould be avoided.

3. The relevance of many CBD Articles anddecisions to NTFR use offers a great opportuni-ty, given the political will, for implementation ofmeasures that can make a major contribution tohuman welfare and the three main objectives inArticle 1 of the CBD. In industrialized countries,NTFR use is often viewed as a marginal activity,though in reality the trade of these products pro-vide significant economic benefits to many ruralhouseholds and communities (Chamberlain etal. 2000). In many developing countries, the per-ception is quite the opposite. NTFR are in dailyuse throughout the tropics, commonly providingresources crucial to people where no other socialsecurity is provided by the state. In a typicalAfrican country, only one person in ten has a for-mal job (The Economist, 2000) and economical-ly important species provide a source of informalsector income. Edible wild foods (fruits, wildvegetables, fungi, bush meat and insects) com-monly provide dietary supplements(Cunningham and Davis, 1997). Fuelwood orcharcoal, not electricity or oil is the major sourceof household energy (Leach and Mearns, 1988).Nine out of ten people live in informally builthouses; eight out of ten people consult tradition-al healers (Aké Assi, 1988).

on major findings, a number of proposals toaddress the negative effects of unsustainable har-vesting of non-timber forest resources are pre-sented. The document is based on the reviewprepared by the Center of international ForestryResearch (CIFOR) commissioned by theSecretariat to the Convention on BiologicalDiversity.

5. In terra firme forest in Amazonia, for exam-ple, Prance et al (1992) recorded that 78.7% oftree species were used by the Ka’apor and 61.4%by the Tembe indigenous peoples. The subsis-tence value of forests to people is difficult to eval-uate, as these products are freely harvested forhousehold consumption rather than for sale. Intheir study of direct-use values of tropical moistforest foods to the Huottuja (Piaroa) people inVenezuela, however, Melnyk and Bell (1996) pro-vided the equivalent of US$ 4696 per householdper year in a small village and US$ 1902 perhousehold per year in the large village studied. Inother cases, the tastiest, most popular fruits entertrade. In their study of edible fruits sold in themarketplaces of Iquitos in the Peruvian Amazon,for example, Vasquez and Gentry (1990) record-ed over 57 wild-collected fruit species being sold.The diversity of medicinal plant species enteringlocal or international markets is even higher. InIndonesia, Siswoyo et al. (1994) list 1260 speciesof medicinal plants being sold, many wild-col-lected species from forests. In South Africa, 400-500 species are sold for traditional medicines,99% are wild harvested (Cunningham, 1988,1991; Williams, 1996). In their study of market-places in Mexico, Bye and Linares (1985) foundthat of the 114 species sold, 28 species were gath-ered from wild habitat, 52 species gathered fromanthropogenic vegetation types, 32 species weredomesticated and 2 species were non-domesti-cated species in cultivation.

6. The number of medicinal products found intemperate climates is staggering, as well. InGermany, Lange & Schippmann (1997) havedocumented 1543 medicinal plant species com-prising 854 genera in 223 families in import orexport trade, 70-90% of which are primarily har-vested from the wild (Lange, 1997). According toFarnsworth and Morris (1976), 25 percent of allprescription drugs dispensed in the United Statesover the last several decades have containedactive ingredients extracted from higher orderplants. Foster and Duke (1990) catalogued morethan 500 species native to Eastern and Central

North America that are valued for their medici-nal properties. In a report prepared by TRAFFICNorth America (1999), at least 175 plant speciesnative to North America are found in the non-prescription medicinal market in the UnitedStates and more than 140 medicinal plants nativeto North America are in international markets.In the Appalachian region of the United States, aregion of global biodiversity importance,Krochmal et al. (1969) identify more than 150medicinal plant species.

7. At the same time, a great many species arecollected for other reasons, besides medicines orfood. Emery (2001) found that rural householdsin northern Michigan of the United States col-lected 138 NTFR for non-market motives. InBritish Columbia, Canada more than 200 botan-ical forest products have been identified, many ofwhich are used for decorative purposes (de Geus,1995). Thomas and Schumann (1993) identifymore than 50 species native to the United Statesthat are harvested for the floral and greenerymarkets. In the Appalachian region of the UnitedStates, more than 30 species have been identifiedthat are valued for decorative markets (Nelsonand Williamson, 1970).

8. By contrast, most bush meat obtained byhunters in tropical forests comes from a relative-ly small number of large-bodied species, normal-ly the larger ungulates and primates (Bennett &Robinson, 2000). Two species, the commonwoolly monkey and collared peccary make up44% of the wildlife biomass harvested by theHuaorani in Ecuador (Mena et al., 2000).Similarly, in Sarawak, Malaysia, three ungulatespecies, bearded pig and two barking deerspecies, comprised 80% of biomass hunted(Bennett et al., 2000) although at least 26 mam-mal species, 12 bird species and 5 reptile speciesare regularly eaten. In Colombia, for example,Maracá Indians killed at least 51 bird species,including 10 hummingbird species (Ruddle,1970) and the Sirionó Indians of Bolivia hunt 23mammals species, 33 bird species and 9 reptile

species. In the Central African Republic, hunters using snares capture 33 mammal species, 7 reptilespecies and 3 bird species (Noss, 2000) and in the Lobéké area of Cameroon, hunters took at least 36 ani-mal species (Fimbel et al., 2000).

9. Speaking of wildlife often disregards the important protein and food source of fish, shellfish andcrustaceans. These resources are not just important as a subsistence resource, providing an importantaddition to the daily diet of many people living in or nearby forest streams or rivers, but also can pro-vide important cash incomes (Rodríguez, 1992, 1998). Dynamics of aquatic resources are partially dif-ferent from the forest and specific attention to this NTFR should be considered in the relevant thematicprogrammes of the CBD.

Page 14: CBD Technical Series 6

3.1. Economic values10. Despite the immense importance of non-timber forest plant resources, their value is rarelytaken into account in land-use planning (seetable 2). Nor are the economic values of theseproducts and the services they provide rarelytaken into account in assessing Gross DomesticProduct (GDP). These omissions need to be cor-rected, as NTFR make particularly significantcontribution to household incomes of the ruralpoor. Rural people, moving from a subsistencelifestyle to a cash economy, have relatively fewoptions for generating income. They can sellagricultural or pastoral produce, work for a cashwage in agriculture or industry, or sell retailgoods in local or regional marketplaces. For therural poor without land or livestock, harvestingof wild resources is a common option. Wild andnaturalized plants provide a "green social securi-ty" to billions of people in the form of low costbuilding materials, income, fuel, food supple-ments and traditional medicines. In some casesthe revenues earned with commercialised NTFRis the only source of cash income, which increas-es the dependency of the people on these com-mercial interesting NTFR resources (van Andel,2000).

11. Cash income from the sale of NTFR can bevery variable, however, even for the sameresource category. Earnings vary from a few dol-lars for ad hoc sales to several thousand US$ peryear. In rural Madhya Pradesh, India, for exam-ple, NTFR provide 40-63% of total annualincome (Tewari and Campbell, 1996). Acrossseven study areas in southern African, wild plantresources contributed US$194-$1114 per house-hold per year (Shackleton et al., 2000). In gener-al, returns to labour from NTFR sales are usuallyhigher than the average local agricultural wage,with income usually higher for externally mar-keted products. Subsistence values are often alsohigh, particularly for poorer rural households. InZimbabwe, for example, Cavendish (1997) calcu-lated that these subsistence ("non-market") val-ues contributed 35% of total household incomes.

12. In 1996 the estimated value of the globalmarkets for all herbal medicines (cultivated andwild harvested) was approximately US$14 billion(Genetic Engineering News, 1997). Europe wasthe largest market representing one-half of theglobal trade. Asia commanded approximately 36percent of the global market. The estimated sizeof the North American market for herbal medi-cines in that year was approximately US$4 bil-lion. In 1998, the total retail market for medici-nal herbs in the United States was estimated at$3.97 billion, more than double the estimate forNorth America in 1996 (Brevoort, 1998, GeneticEngineering News, 1997)

13. Panax quinquefolium (American ginseng) isperhaps the most popular and valued medicinalherb exported from North America. This medic-inal plant, which is native to the hardwoodforests of eastern North America, has beenexported primarily to Hong Kong, Taiwan, andmainland China for more than 300 years. From1993 through 1996, the volume of forest-harvest-ed ginseng exported from the United Statesincreased more than 175 percent, from 69,000 kgto 191,500 kg (USDA, 1999). The export valueranged from US$20.7 million to US$30.47 mil-lion. At the same time, the volume of cultivatedAmerican ginseng exported in 1996 was approx-imately 674,000 kg, and valued at only US$20,2million. Forest harvested ginseng typically commands a price 10 times that of cultivatedginseng.

3.2. Nutritional values14. Starchy staple food from a few species ofcultivated plants form the bulk of peoples foodin the tropics - either rice, maize, sorghum ormillet (Gramineae), cassava (Euphorbiaceae) orpotatoes (Solanaceae). In some parts of the trop-ics, the starchy staple foods are from sago palm(Metroxylon sagu), taro (Colocasia esculenta) orarrowroot (Maranta arundiacea). Bush meatcommonly provides an important protein sourcein the tropics and gathered plant foods animportant source of dietary supplements to thestarchy staple diet. Even where there has been achange from a hunter-gatherer lifestyle to pas-toralism or agriculture, hunting and gatheringremain important to a high proportion of ruralhouseholds in African woodlands (Campbell et

al, 1991; Cunningham, 1988a; Wilson, 1990) andtropical forests (Koppert et al., 1993). Wild plantfoods are well known from studies in Africa, Asiaand Latin America to be a valuable source ofthese nutrients deficient in starchy staple diets,particularly nicotinic acid from wild spinaches(Santos-Oliviera and Carvalho, 1975), vitamin Cfrom wild fruits (Quin, 1959; Wehmeyer, 1966)and protein from Sclerocarya birrea,Schinziophyton rautanenii and Tylosema esculen-ta seeds and edible insects (Quin, 1959). InAppalachian forests of eastern United States, thenative Americans depended on the greens andbulbs of Allium triccocum (ramps), which appearearly in the spring, for much needed vitaminsafter a long winter with no fresh vegetables.

3.3. Social and cultural values15. The social and cultural values linked tofoods and medicines are a reflection of the valueplaced on NTFR. Even airfreight is used to trans-port edible and medicinal plants, regionally orinternationally to meet culturally drivendemand. An estimated 105 tonnes of "bushplums" (Dacryodes edulis) and 100 tonnes of"eru" (Gnetum africanum and G. buchholzianum)leaves are exported, for example, fromCameroon, Congo, Gabon and the Democraticrepublic of Congo as foods for West Africans liv-ing in France and Belgium (Tabuna, 1999).

16. Western and traditional medicines are basedon very different and well-documented views ofhealth and disease. Traditional medicine takes aholistic approach where disease or misfortuneresult from an imbalance between the individualand the social environment while western medi-cine takes a technical and analytical approach.These different approaches to the causality ofdisease are one of the reasons why demand fortraditional medicine continues in the urbanenvironment even if western biomedicine isavailable. Another reason is that western medicalcare is more expensive and very limited inremote rural areas.

17. International trade in Chinese traditionalmedicines, in kava (Piper methysticum) to expa-triate Pacific islanders living in North America orthe African medicinal plant khat (Catha edulis)to Somali communities in Europe and NorthAmerica are other examples. A recent surveyamongst 70 Somali people in Liverpool,England, for example, found that 43% of menhad used khat, with 39% chewing it on a dailybasis (Berry, 1996). Remarkably for a product inlong-distance trade, the young leaves of Cathaedulis need to be chewed while still fresh for maxi-mum effect - and for this reason, the price of khatrapidly drops with time. As a result, the trade hasto be highly organised to get leaves from the farmto the end-user as soon as possible.

18. There is a deep-rooted cultural bond toNTFR collection and use. When the earlyEuropean settlers immigrated to North America,they brought with them items essential to sustaintheir lives. When these stores were depleted, theylooked to the local forest resources and learnedfrom the Native Americans which plants wereuseful and how to use them. Much of the knowl-edge gained from Native Americans is the foun-dation of the herbal medicinal industry today.Many rural collectors can trace their bond toNTFR collecting back more than 400 hundredyears. The knowledge that present-day collectorshave about NTFRs could prove invaluable indeveloping appropriate management strategies.

19. For many products, harvesting takes place inlandscapes changed by people due to farming,fire or livestock, even where human populationdensities are very low. In the Brazilian Amazon,for example, with an average human populationdensity of about 1 person/km2, at least 11.8% ofterra firme forest is an anthropogenic result ofswidden agriculture, human settlement andplant domestication (Balee, 1989, 1993). In allsavanna systems, fire is a frequent source of dis-turbance (Scholes and Walker, 1993). By the timeof European contact, most of Australia, with ahuman population far lower than Amazonia, wasbeing deliberately burnt as a means of managingfood production density (Latz, 1995). Direct useof resources is thus superimposed upon theeffects of natural and/or anthropogenic distur-bance. In some cases this enhances species popu-lations and in others, diminishes them. Manyspecies of bamboo, thatch-grasses (Hyperthelia,Imperata, Cymbopogon), edible leafy greens(Acanthaceae, Amaranthaceae, Capparaceae)and sources of bark fibre (Tiliaceae, Malvaceae)are often widely distributed, light demandingplants whose populations increase in response todisturbance. Anthropogenic disturbance alsooccurs at smaller scales. Examples are the delib-erate planting of useful species in forest patchesor along paths such as by the Kayapó inAmazonia (Posey, 1984), propagation ofCanarium and Landolphia by Mbuti in the Ituriforest (Ichikawa, 1999) or the protection of val-ued species, replanting the tops of wildDioscorea tubers, transplanting palm suckers, ona sufficiently systematic basis for this to be con-sidered 'rainforest management' (e.g.: Alcorn,1981).

20. In the past, under subsistence demand, har-vesting of plant-based NTFR rarely resulted inspecies-specific overexploitation. Now, ruralcommunities in many parts of Africa, Asia,Central Europe and the Americas are increasing-ly concerned about losing self-sufficiency as theirlocal wild populations of favoured, popular plantspecies are cut down or dug up, bundled or

bagged and transported to far-away regionalmarkets. Similar concerns apply to animals usedfor bush meat, as the wildlife biomass of tropicalforests is generally low. In Amazonia, for exam-ple, the protein intake of the Yuquí Indiansdropped from 88 g to 44 g per person per dayafter large-scale invasions by colonists between1983 and 1988 (Stearman, 2000). Wildlife huntingmay be sustained but only where human popula-tion densities are low (Bodmer et al, 1994). Basedon a recent review of studies on hunting in tropi-cal forest, Bennett and Robinson (2000) suggestthat for people depending exclusively on wildmeat, hunting may not be sustainable if humanpopulation densities >1 or 2 person/km2. Wherepeople shift from subsistence to a cash economy,frequency and intensity of harvesting or huntingchange rapidly, for example in response to com-mercial demand stimulated by increased access(e.g.: road construction for logging). The bushmeat trade (Bennett and Robinson, 2000) as wellas some rattan, craft, horticultural and medicinalplant species all provide examples of this situation(Cunningham & Milton, 1987; Donaldson, inpress; Dransfield, 1981; Nantel et al, 1996).

21. Whether NTFR or bush meat use is consid-ered from the perspective of local livelihoods orconservation, species loss through overexploita-tion benefits neither local people nor conservationin the long term. Unrestricted access to valued butvulnerable species may provide a high initial har-vest, but this will merely be a temporary "bonanza"followed by loss of local self-sufficiency and high-er effort or prices to get the species elsewhere. Inmost cases, habitat loss is the initial underlyingcause of threat. Increasingly, however, species spe-cific over harvesting of some plant and animals isbecoming a significant factor as habitats shrinkand demand for valued, but vulnerable speciesincreases. Substantial proportions of some of theworld's most useful plant families are currentlythreatened by either habitat loss or species-specificoverexploitation (or a combination of these twofactors).

22. It is often assumed that NTFR are sustain-ably harvested and that this "green social securi-ty" will always be available to resource users. Thisis not always the case. In many parts of the world,local people are losing access to valued plant andanimal species, either through overexploitationand habitat destruction or loss of access as for-mer harvesting areas are included within nation-al parks or forest reserves. For all interest groups,whether resource users, rural development work-ers or national park managers, it is far better tohave pro-active management and to stop orphase out destructive harvesting in favour ofsuitable alternatives before overexploitationoccurs, than to have the "benefit" of hindsightafter resource depletion.

23. A problem is that little is known about thepopulation biology, standing stocks or yields ofmost plant species that are harvested for non-timber forest products. Tropical forests, forexample, are remarkably diverse, yet poorly stud-ied by scientists. Many tropical species are notdescribed and even less is known about the pop-ulation biology or ecological interactionsbetween species. Though, temperate forestspecies may be better studied, for many temper-ate NTFR little more is known than basic taxon-omy and the geographic distribution. There is ageneral lack of knowledge about the reproduc-tive biology, inventories, and sustainable yields.Even if encouraging new initiatives such as theGlobal Taxonomy Initiative were implementedtomorrow, we still need to find ways to prioritiseNTFR species as components in the implementa-tion of conservation and sustainable use plans.

24. Due to the diversity of forest ecosystems andNTFR, our limited "scientific" knowledge andthe ecological and taxonomic insights held byknowledgeable local and indigenous people, it isrecommended that more use should be made offolk taxonomists. Where formally trained taxon-omists are not (and unlikely to become) avail-able, local folk taxonomists can be remarkablyeffective. In India, for example, local people in

selected areas are involved in "community biodi-versity registers" (Gadgil, 1996; Ministry ofEnvironment and Forests, 1997) in a process thatdocuments biodiversity at a landscape level andthe processes driving change. This experimentalprocess is worth pursuing in other parts of theworld.

25. The greatest contribution by folk taxono-mists will probably be in the inventory and pop-ulation biology of useful species such as edible ormedicinal plants or animals. In Australia, wherereptiles are commonly hunted for food, local folktaxonomy can be crucial at filling gaps in knowl-edge about reptile-taxa (Baker and MutitjuluCommunity 1992). Kinabalu Park in Sabah,Malaysia, with over 5000 plant species has longbeen a famous site for botanical richness. Thisenabled a comparison of the number of palmspecies collected by professional botanists visit-ing Kinabalu from the 1850's onwards with thosemade by community-based collectors. They, injust 3% of the time in which professionalbotanists were active, were able to increaseknown palm genera by 82%, species andintraspecific taxa by 65% and the number of col-lections by 103% (Martin et al, 2001). Traditionalecological knowledge can provide valuable infor-mation on stewardship practices for sustainableNTFR use (Emery, 2001a).

26. Vulnerability or resilience to harvesting isinfluenced by the level of demand and by com-mon biological characteristics: life form (plants)or body size (animals), growth rate, reproductivebiology, geographic distribution, habitat speci-ficity, population density, etc. (Cunningham,1991; 2001; Peters, 1983; Peters, 1994).Harvesting of leaves, flowers or fruits (or eggs)from widely distributed, fast growing, fast repro-ducing species occurring at high densities in arange of habitats is obviously of less concernthan the killing of large, slow growing, infre-quently reproducing species.

27. The effects of harvesting on a plant popula-tion depend on what part of the plant is harvest-ed and on the quantity, intensity and frequencyof harvesting. Most harvesting has some effect,but extirpation is infrequent and extinction evenmore rare. It is usually a function of habitatdestruction coupled with commercial harvestingof restricted range species. The effect of harvest-ing is particularly acute when the roots, fruitingbodies or other reproductive organs areremoved. With many medicinal plants, the rootsare harvested thus severely limiting reproductivecapability. The barks of other medicinal plantsare stripped from the live plant, increasingtremendously the likelihood of mortality.Although the response of individual plants is auseful guide to estimate harvesting impact, it iscrucial to avoid getting side-tracked when seeingdestructive harvest at the individual level and totake into account geographic distribution, habi-tat specificity, growth rates, conflicting uses,reproductive biology and management costs.

28. Harvested populations in turn need to beviewed in terms of abundance, distribution andresponse to disturbance at the landscape level(Cunningham, 2001). A seemingly low impactuse, such as harvesting of fruits for example, mayhave a high long-term impact on populations ofsome species, either because of long-term impacton seedling recruitment (Peters, 1994) orbecause fruit collection involves tree felling. Onthe other hand, even if harvesting bark, roots,stems kills some individual plants, it may havelittle impact on the populations of fast growing,fast-reproducing species. In Guyana species richmixed forests contain more NTFR species thanspecies-poor swamps. However this diversity isnot a prerequisite for economically viable andecologically sustainable NTFR extraction. Low-diversity forests offer better opportunities forsustainable single-species extraction, as they aredominant by economically important species(van Andel, 2000).

Page 20: CBD Technical Series 6

29. Forest and woodland fragmentation resultsin harvesting and hunting focused on theremaining source areas, including national parks(and even botanical gardens!!). In terms of peo-ple's harvesting, a decline in area covered by veg-etation types with characteristic species associa-tions is highly significant to conservation andresource management programmes. For this rea-son, understanding what drives deforestation(Kaimowitz and Angelsen, 1998) and resultantpolicy change are directly relevant to sustaineduse of NTFR.

30. Firstly, this represents a decline in wildlifespecies (Cuaron, 2000) and in the availability ofplant species that was or would have been usedby local people. Working in 2.7 million ha ofsouthern Mexico and northern Guatemala, forexample, Cuaron (2000) showed a decliningtrend in habitat availability for 32 (59%) of the54 wildlife species. Secondly, it means that theremaining blocks of vegetation become the focusfor more frequent and intensive harvesting ofhigh value species, for both bush meat (e.g.,Fitzgibbon et al., 1995) and plant products (e.g.,Cunningham, 2001). Periodic assessment of theextent and rate of loss (or expansion) of habitatat a landscape level using aerial photographs orsatellite images are a common, cost-effective wayto monitor the success or failure of conservationprogrammes, but they do not give the full-pic-ture. Forest or woodland cover may not change -but underneath the canopy, populations of highvalue, vulnerable plant and animal species can bedisappearing due to species specific overexploita-tion: the "empty forest" phenomenon describedby Redford (1993) for wildlife. This situation israrely taken into account in protected area man-agement. For these reasons, monitoring at a largespatial scale needs to be combined with monitor-ing of a high value "indicator" species at a popu-lation level to give a comprehensive picture.

5.1. Biological factors 31. Differences in climate, soil and vegetationtype result in significant differences in the avail-

ability and use of NTFR across tropical and tem-perate climates. Large areas of the tropics arecovered by sandy, nutrient poor soils. Examplesare terra firme forest in Amazonia, heath (keran-gas) forests in Borneo, in south-central Africa,Zambesian dry evergreen forests on Kalaharisands (dominated either by Cryptocephalum,Parinari excelsa or Marquesia macruora), themonodominant Gilbertiodendron dewevreiforests in the Congo basin and in eastern Africa,dry deciduous forests on coastal plain sands. Ineach case, the relatively low productivity of theseforests, with consequently low carrying capaci-ties for hunting communities, suggests thathunting may not even be sustainable wherehuman population densities are less than 2 per-sons/km2 (Bennett and Robinson, 2000).

32. In the case of wild plant use, yields fromwild populations are often overestimated.Whether fruits, roots, bark or whole plants areinvolved, the potential yield from wild stocks ofmany species is frequently overestimated, partic-ularly if the effects of stochastic events are takeninto account. As a result, commercial harvestingventures based on wild populations can be char-acterised by a "boom and bust" situation whereinitial harvests are followed by declining resourceavailability. In their work on American ginseng(Panax quinquefolium) in Canadian temperateforests, Nantel et al (1996) found the extinctionthreshold below 30-90 plants. The minimumviable population was estimated at 170 plantsbut only a dozen populations were larger than170 plants, so most cannot support any harvest-ing if they are to be maintained in the long-term.The low level of extraction required to ensuresustainable harvesting of wild populations ofAmerican ginseng (Panax quinquefolium) as wellas wild leeks (Allium triccocum) in Canada(Nantel et al, 1996) and amla tree (Phyllanthusemblica) fruit in India (Shankar et al, 1996) allsuggests that at current prices, sustainable har-vest levels for these species were not an econom-ic propositions for commercial gatherers.

Page 21: CBD Technical Series 6

5.2. Change in socio-economic factors 33. Transport systems are reaching further andfurther into remote, resource-rich regions,catalysing settlement, and forest and woodlandclearing. This results in the loss of supplies of wildharvested species as habitat declines and trade ofbush meat and wild plant species increases. Forthese reasons, Wilkie et al. (2000) highlight theneed, through co-ordinated land-use and infra-structure planning, to plan roads in a way thatmaximises local and national economic benefitswhile minimizing the negative effects road con-struction has on biodiversity.

34. Improved transport networks strengthen thelink between rural resources and urban demand.They also result in an influx of outsiders, frequent-ly disrupting traditional resource tenure systemsand increasing the scramble for economically valu-able resources. As cities grow, the markets withinthem exert stronger and stronger pull on ruralresources. Over the past century, there has been anunprecedented flood of people moving from ruralto urban areas. At present, the highest rate ofurbanisation, 6% per year, is in sub-Saharan Africa.In South Asia, the rate is 4% per year. Godoy andBawa (1993) suggest that economic development"encourages rural to urban migration, lowers pop-ulation growth, and supports more productiveagriculture, all of which should decrease pressureon the forest as a source of livelihood". Since the1960's, the growing demand from urban areas hascatalysed NTFR trade, drawing in resources fromrural areas to towns and cities, for favoured fuel-wood, building materials, medicinal or edible wildfruit species. From first harvest to final sale, thistrade in wild plants and bush meat for local,national or regional consumption forms part of aninformal sector "hidden economy". This informalsector trade continues to be very important in thecities of many developing countries, as the urban-rural divide is rarely a clear-cut one. As a result,urbanisation has tended to increase rather thanreduce the demand for wild plant resources,catalysing a commercial trade that stimulates over-exploitation.

35. International trade in NTFR is more obvi-ous, as middlemen link the informal sector to anexport sector for which export or import recordsare sometimes kept. For example, around 500people, mostly women sell more than 700 metrictons of aguaje (Mauritia flexuosa) palm fruiteach day in Iquitos (Padoch, 1988). Of the 700full-time NTFR traders in the daily urban mar-kets of Kumasi, Ghana, 90% of whom werewomen, 100 traded in leaves of Marantaceaewith the monthly demand for Marantochloaleaves exceeding US$47 000. Of the 100 people,also mainly women, who traded in medicinalplants, 65 were full-time bush-meat traders, 50traded smoked meat, 15 fresh bush meat, sellingan estimated 160 tons of meat/yr with an annualvalue of US$209 000 and 25 were full-time bas-ket traders, selling 1000-5000 baskets/month(FAO, 1995a). In Gabon, the bush meat trade hasbeen valued at $22 millions/yr for informal mar-kets and $3 millions/yr from formal markets,with four tonnes of bush meat entering Librevillemonthly (Inamdar et al., 1999).

36. A study of the segment of the floral industrythat deals with forest-harvested greens in thePacific Northwest of the United States found thatprocessors purchased US$47.5 million worth ofconifer boughs and other floral greens(Schlosser, Blatner and Chapman, 1991). Thissegment contributed US$128.5 million to theregional economy at the wholesale level in 1989,and supported more than 10,000 seasonal andpermanent jobs.

37. The shift from subsistence use to commer-cial sale has important implications for resourcemanagement as it results in larger volumes beingharvested, a higher frequency and intensity ofharvesting and often affects resource tenure. Insome cases, commercial harvesting strengthensresource tenure and the incentive to conserveindividual plants. Commercial sale of wild fruitssuch as Sclerocarya birrea, for example, maintainsthe incentive to conserve wild fruit-bearing treesin parts of Africa where development of a social

16

Page 22: CBD Technical Series 6

stigma against gathering wild fruits as a foodresource is undermining the "traditional" prac-tice of conserving wild fruit trees. In others, theshift from subsistence use to commercial har-vesting weakens resource tenure and underminescustomary controls of resource use.

38. Although access to markets is a key factor inrealizing economic values of NTFR (Neumannand Hirsch, 2000), the ingenuity of peopleaccessing markets if there is sufficient economicincentive should not be underestimated. The useof helicopters to (often illegally) transport thearomatic gaharu resins (Aquilaria trees) fromremote South-Eat Asian forests to internationalmarkets is a good example (Momberg et al,2000). If prices and profits are high enough, localtraders will also make remarkable use of anytransport network to get perishable species to themarket. As road networks extend into more andmore remote rural areas, so commercial har-vesters or middlemen flow in, and favoured plantspecies flow out.

39. Local gatherers often get a low and highlyvariable price for unprocessed plant material atthe start of these complex marketing chains fromrural gatherers harvesting wild species to urbanconsumers. Although income from Prunusafricana bark sales is an important source of rev-enue to villagers in Madagascar, in some casesgenerating >30% of village revenue, the pricepaid to collectors is negligible compared to mid-dlemen (Walter and Rokotonirina, 1995). InMexico, Hersch-Martinez (1995) found thatmedicinal plant collectors only received an aver-age 6.17% of the medicinal plant consumer price.In India, the extent by which the prices of NTFP'sincreased from along the marketing chain fromthe point of collection varied from an increase of50% for Decalepis hamiltonii to 255% in soapnut(Acacia sinuata) sales (Hedge et al., 1996). On thebasis of their study, Hedge et al. (1996) consideredthat one consequence of low prices to harvesterscould be overexploitation and conversely,increased income through value-addition and

processing could provide an incentive to decreaseharvest levels. For this reason, for example,Shankar et al. (1996) have recommended an alter-native flow of amla (Phyllanthus emblica) fruit inIndia from the forest source area to the Indianconsumer, improving economic benefits to har-vesters as a means of improving householdincome while reducing over harvesting of fruits.Their model is widely applicable, as is the JointForest Management (JFM) system developed forNTFR harvest and timber production in Shorearobusta forests in West Bengal, India, which hasalso been applied in Nepal (Hobley, 1996). Next tothe systems such as Joint Forest Managementanother important and potential fruitful systemhas been developed. Analogue Forestry, which wasinitially started in the home-gardens of Sri Lanka,has now been applied in numerous other coun-tries and proven quite successful in combiningbiodiversity with NTFR production and harvest-ing (Senanayake and Jack, 1998; Mallet, 2000).

40. Low prices paid for medicinal plants, whetherfor local or export markets, often bear no relationto the real cost of resource replacement. Lowprices also mean that few slow growing species arecultivated and that cultivation for profit is restrict-ed to a small number of high priced and/or fastgrowing species.

5.3. Disappearance of cultural and religious values41. The assumption tends to be that "economicdevelopment" means that electricity, kerosene orgas for lighting and household cooking is sup-plied at low cost to the majority of the urbanpopulation. However this is often not the case inthe shantytowns that sprawl around the rapidlygrowing cities of most developing countries. Thecultural and economic importance of wild plantsto urban people is a crucial factor, which also hasto be taken into account. Common examples inmany cities in Africa, Asia and Latin America arethe sale of wild-collected medicines, chewingsticks, indigenous foods and bush meats valuedby urban people.

42. Cultural systems are even more dynamicthan biological ones, and the shift from a subsis-tence economy to a cash economy is a dominantfactor amongst all but the remotest of peoples. Inmany parts of the world, "traditional" conserva-tion practices have been weakened by culturalchange, higher human needs and numbers and ashift to cash economies. There are an increasingnumber of cases where resources which were tra-ditionally conserved, or which appeared to beconserved, are being overexploited today. Thepeople whose ancestors hunted, harvested andvenerated the forests that are the focus of enthu-siastic conservation efforts are sometimes thepeople who are felling the last forest patches formaize fields or coffee plantations, often on slopesso steep that sustainable agriculture is impossi-ble. In other places, local human populationshave decreased due to epidemic disease or evenurbanisation, with swidden agriculture onlyoccurring on old secondary forest. While someresources are being over harvested due to cultur-al and economic change, the majority are stillused sustainably, and the impact on others haslessened because of social change. In the mostextreme cases, "islands" of remaining vegetation,usually created by habitat loss through clearingfor agriculture, then become focal points for har-vesting pressure, and sites of conflict overremaining land or resources.

Page 24: CBD Technical Series 6

6.1. To achieve a balance between conservationand sustainable use of non-timber forestresources, there is a need to consolidate protect-ed area networks and establish and maintaincorridors (Article 8a) through:i. Identification and legal protection of cur-

rently unprotected sites that are a priorityfor conservation of biological diversity andecosystem processes and, where necessary,increase of the effectiveness of existing pro-tected area management.

ii. Putting in place land-use mosaics favourableto the conservation goals of the adjacentprotected areas. The form this takes will varywith social, political and economic circum-stances, comprising conservancies, "landcare" groups, multiple-use zones, co-man-agement areas or indigenous productionforests. Firm, mutually agreed and enforce-able regulations need to be established.

iii. This should be planned at an ecosystemscale to create biological corridors formigratory species and maintain minimumviable populations of conservation priorityspecies.

6.2. Land-use and infrastructure planning(roads, new settlements) need to take intoaccount protected areas, their adjacent conser-vancies or co-management areas and therequirements for maintaining viable popula-tions of valued, but vulnerable species.These should not block migration routes, resultin the destruction of high conservation priorityhabitats or stimulate the overexploitation of highconservation priority species (such as rattan,medicinal plants or bush meat) through unregu-lated commercial trade.

6.3. Ecosystem level and harvested/hunted pop-ulation management planning must take placethrough a process of consultation that takes intoaccount relevant scientific, local and indigenousknowledge.This should recognize the role of cultural land-scapes (with their botanical and cultural diversi-

ty) and include support to local or indigenouspeople trying to protect their biological and cul-tural heritage from external incursions such asindustrial logging, large dams or industrial scaleagriculture.

6.4. Development and implementation of effec-tive conservation and resource managementplans may need legislative reform before man-aged use of non-timber forest resources pro-vides incentive for conservation as a form ofland-use (Article 8k).Examples are the development of national legis-lation in Namibia that recognizes communityrights to values derived from wildlife within co-managed conservancies. An example of the con-verse is national legislation in Australia whichdenies indigenous people commercial access toindigenous species (birds, reptiles, marsupials)even where viable harvesting is possible as amore appropriate form of land use than sheep(ACIL Economics, 1997). In Côte d’Ivoirewildlife hunting is registered as an illegal activity:poaching. This legislation hampers the develop-ment of regulations on wildlife management andmany households in the vicinity of Taï NationalPark depend on the market trade of bushmeat.Therefore it is recommended in this specific caseto support the drawing up of the necessary con-ditions for the reopening of hunting in Côted’Ivoire (Caspary et al, 2001).

6.5. Legislative change, technical support andeconomic incentives for ecological restoration ofwildlife corridors and for the control of invasiveplant and animal species may be necessary formaintenance or re-establishment of viable pop-ulations of indigenous plant and animal popula-tions.

6.6. Training: recognize and strengthen the roleof local people in inventory, research, monitor-ing and impact assessment processes, and man-agement (Article 12):i. A folk taxonomy initiative should be formed

as a separate, new component within the

19

6. Recommendations

Page 25: CBD Technical Series 6

current Global Taxonomy Initiative, whichhas been established as a means of promot-ing taxonomy and taxonomic tools forimplementation of the Convention.Traditional ecological knowledge of localand indigenous peoples about the ecologyand use of NTFR species needs to be docu-mented, strengthened, respected, and devel-oped. The role of local people in tropicaltaxonomy initiatives has also been recog-nized in Costa Rica (Janzen et al., 1993) andBrazil, concentrating on the collection andcataloguing of wasps, beetles, vertebrate par-asites and fungi specimens. A recent exam-ple of this, concentrating on insect pollina-tors, is the document prepared by BrazilianMinistry of the Environment as a contribu-tion for the implementation of DecisionIII/11 of the Convention on BiologicalDiversity which established a work programon the conservation and sustainable use ofagricultural biological diversity (Dias, Rawand Imperatri–Fonseca, 1999).

ii. There is a great need for training (CBDArticle 12a) of young professionals and thestaff of agencies responsible for the manage-ment of NTFR and wildlife resources towork effectively with the local harvestersand their communities, private owners andthose working for commercial enterprises.This will require Technical and scientificcooperation (Articles 18 and 25c).

iii. The role of local and indigenous peopleshould not only e recognized in inventory,research, monitoring and impact assessmentprocesses but also in the management itself.Cases in Colombia have proven that localindigenous management of naturalresources but also research is quite success-ful (Rodríguez and van der Hammen, 1999)

6.7. Appropriate and economically viable moni-toring systems should be developed and estab-lished at the landscape level (remote sensing,aerial photograph analysis) and local level (indi-cator species) (Article 7)

Involvement of local people in this process,through both mapping and monitoring shouldbe considered, particularly for countries withlimited numbers of trained personnel. Efficientsystems for data storage, analysis and the returnof results to local people must accompany thisprocess.

6.8. Integrate non-timber forest resources usesinto forest management and land use planning:Non-timber forest products need to be recog-nized by forest management agencies as naturalresources and fully integrated into forest man-agement planning and activities. NTFR shouldreceive similar attention in forest management asother natural resources, such as timber, minerals,and water. Silvicultural prescriptions need to bedeveloped that consider and incorporate NTFR.The opportunity for better co-ordinated inven-tory and management to avoid wastage shouldinfluence the choice of natural forest logging sys-tems and how these influence non-timber forestproducts. Forest management planning needs toconsider the implications of removing thecanopy, due to logging, on understorey NTFR.Although many tree species have multiple usesaside from timber, this is rarely taken intoaccount in forest inventory or management.Exceptions to this are forest departments inFinland, which uses double-inventory methodsto develop management plans for berry yieldingshrubs and for edible mushrooms(Saastamoinen et al., 1998) and the Nepal Forestdepartment, which has recently included NTFRin its five-year planning process (Wong, 2000).There is a great opportunity for SBSTTA to stressthe need for inclusion of NTFR in forestry plan-ning processes, as logging impacts can have a fargreater impact than harvesting on some NTFR.

6.9. Conservation through cultivation or farm-ing of wildlife, which is economically viable andon a sufficient scale to take the pressure off wildstock:Wild harvest is not always the answer, particular-ly under high demand. While managed sustain-

20

able use of wild populations is theoretically pos-sible in high species diversity systems such asforests, it requires such high inputs of moneyand manpower that exploitative use is likely tooccur. Cultivation can be a cheaper and morepractical option. If cultivation is to be a successin providing an alternative supply of overexploit-ed plant species, then plants have to be producedcheaply and in large quantity. Most cultivation orwildlife farming will be competing with materialharvested from the wild that is supplied to themarket by commercial gatherers, who haveincurred no input costs for cultivation. Pricestherefore increase with scarcity due to transportcosts, search time and the long-distance trade. Atpresent, low prices (whether for local or interna-tional pharmaceutical trade) ensure that fewspecies can be marketed at a high enough priceto make cultivation profitable. If cultivation doesnot take place on a big enough scale to meetdemand, it merely becomes a convenient bit of"window dressing" masking the continuedexploitation of wild populations. This is attainedrelatively easily in the case of medicinal species.The regional demand for Scilla natalensis(Liliaceae) in KwaZulu/Natal, South Africa, forexample, was 300,000 bulbs/yr, which are at least8 - 10 yr old from the wild. On a 6 yr rotationunder cultivation at the same planting densitiesas Gentry et al. (1987) used for Urginea maritima(Liliaceae), 70 ha would be required(Cunningham, 1988). Due to their slow growthrates, the rotational area required for tree specieswould be far greater, with total area dependanton demand. Between 3200 and 4900 tonnes ofPrunus africana bark are exploited annually forexport to Europe. In ideal conditions, bark pro-duction rates of Prunus africana are similar ofAcacia mearnsii plantations, which produce 28tons/bark/yr from 12 yr old stands with 1,363trees/ha. Before manufacture of the capsules, thebark extract is standardized to contain 13% phy-tosterols (Mediherb, 1991). Twelve-year-old treeshave about 50% of the phytosterol content, sotwice the current tonnage would presumably berequired. If this is correct, then total annual

world demand for Prunus africana bark could beproduced by a total plantation area of 2743 -4200 ha or a 12 year rotation of a total of 230 -350 ha of trees felled and totally stripped of barkeach year. In Côte d’Ivoire on farm propagationproved successful for Makoré (Tieghemella heck-elii) a local fruit tree. The study showed howeverthat next to the biological, ecological and eco-nomic aspects also socio-economic aspectsshould be taken into account. In the Taï regionwhere the study took place planting a tree wastaboo for the farmers, as they believed that plant-ing a tree was an act exclusively for God and thatthe planter was condemned to die before the treebecame mature. Between 1969 and 1989 the firsttimed steps were set towards actual cultivation offorest fruit trees. The Makoré seed oil - used formaking butter, soap and balm for hair and skin –was the primary motivation for 79% of the farm-ers to domesticate the species. (Bonnéhin, 2000)

6.10. Raise awareness of importer, exporter,manufacturers and retail buyer:Importers and consumers need to become awareof whether the products they consume are har-vested sustainably or not, and bear some respon-sibility for sustainable resource management.Programmes that raise awareness about the "eco-logical footprint" of long-distance trade fromdeveloping to developed countries orCertification programmes such as the ForestStewardship Council (FSC) that may be appliedto some NTFR (Shanley et al., in press) are use-ful tools to achieve this goal. Note that next to theNTFR certification scheme of FSC other certifi-cation schemes exist. Certifying theEnvironmental Management System (EMS) of aforest organisation can be done according inter-national standards (ISA|O 14001/14004), howev-er it does not lead to product labelling. The cer-tification systems on organic agriculture such asthe International Federation on OrganicAgriculture (IFOAM) or the Organic CropImprovement Association (OCIA) deal withNTFR from human altered vegetation types.Finally the Fairtrade Labelling Organization

Sustainable management of non-timber forest resources

(FLO) focuses on socio-economic criteria ofproducts including NTFR. It is important toattune the different certification schemes so theymutually reinforce their processes and avoidpotential conflicts (Maas and Ros-Tonen, 2001).

6.11. Ex situ conservation (CBD Article 9):Secure ex-situ gene banks need to be developed.Commercially harvested, habitat specific, phylo-genetically distinct genera are an important pri-ority (e.g., Panax (6 species, all commerciallyharvested), Warburgia (4 species, all harvested)and Aquilaria (15 species, at least 7 of which areexploited for gaharu). Priority should be given tothose plant species listed on CITES.
