Measuring Conservation Efforts: Developing a monitoring program for Tosonkhulstai Nature Reserve
Tuguldor E. The Nature ConservancyKirk A. Olson University of Massachusetts/National University of Mongolia
No form of wildlife management,
Whether it is the establishment of
cropping or hunting quotas, the
development of tourism, or the
demarcation of boundaries is
possible without reliable information
on the numbers, population
dynamics, and movements of the
animals concerned.
Mike Norton‐Griffiths
Counting Animals, 1978
Objectives
1. To facilitate participatory analysis of
1.1. Condition of species/resources and conservation values, and changes over time
1.2. “systems” and key ecological attributes
1.3. Stresses and sources of stresses on systems
1.4. Key threats on systems
1.5. Linkages of livelihood and natural resources/biodiversity
2. To develop, with local communities and governments, local strategies to reduce threats
3. To compile baseline data on socio‐economy, livestock production and weather patterns, and changes over time.

Major strategies center around:
1. Climate Change mitigation and adaptation in livestock herding.
2. Improved planning and implementation of pastureland and water resources management – bag/soum level, community/household level. Related to climate change impacts, and to changes in livestock production (very large herds, outsiders livestock/horses, loss of traditional seasonal moves)
•Community organization•Agreements (soum/aimag level) on “otor” movements•Limitations on livestock numbers, particularly livestock of absentee herders, race horse owners etc. •Improving livestock products/value addition/marketing, as opposed to increasing numbers
3. Law Enforcement and good governance
4. Education/Training and Public Awareness
5. Improving stakeholder cooperation, co‐management, public and community participation, community organization
Improved vigilance by rangers working in the reserve will lead to an increase in wildlife abundance, particularly those that are hunted for meat or pelts.
Hypothesis:
Selected Target Species:
Mongolian gazelle
Siberian marmot
Corsac fox
Red fox
Is it possible to develop an easy to implement, cost effective monitoring program for these target species?
Marmots:
Compare line transect sampling and area sampling methodology
Carnivores:
Use baited scent stations to develop a record of proportion of stations visited.

• 24 % of untreated stations were visited
• 31 % of treated stations were visited
• 22% of treated stations had sign of ‘Fox’
• 16% of untreated stations had sign of ‘Fox’
• 07% of of untreated stations had ferret sign
• 09% of treated stations had ferret sign
• 2 of the untreated sites had hedgehog visits
Recommendations
Double survey effort for line transects;
Conduct line transect survey along an east – west axis;
Continue to improve quadrat sampling by reducing the size of the known marmot regions ;
Use camera traps to positively ID visitations;
Increase sample size ;
Compare between seasons.
THANK YOU, NOW HAVE ANOTHER BEER
and ENJOY SANJA’S PRESENTATION!!!
