Title On the high trail: examining determinants of site use by the Endangered snow leopard Panthera uncia in Qilianshan, China Type Journal Article
Year 2015 Publication Oryx Abbreviated Journal
Volume Issue Fauna & Flora International Pages 1-8
Keywords Camera Trap, China, Detection Probability, Occupancy Modelling, Panthera Uncia, Site use, Snow Leopard
Abstract Abstract There is a need for simple and robust techniques for assessment and monitoring of populations of the Endangered snow leopard Panthera uncia to inform the de- velopment of action plans for snow leopard conservation. We explored the use of occupancy modelling to evaluate the influence of environmental and anthropogenic features on snow leopard site-use patterns. We conducted a camera trap survey across  km in Gansu Province, China, and used data from  camera traps to estimate probabilities of site use and detection using the single season occupancy model. We assessed the influence of three covariates on site use by snow leopards: elevation, the presence of blue sheep Pseudois nayaur and the presence of human disturb- ance (distance to roads). We recorded  captures of snow leopards over , trap-days, representing a mean capture success of . captures per  trap-days. Elevation had the strongest influence on site use, with the probability of site use increasing with altitude, whereas the influence of presence of prey and distance to roads was relatively weak. Our findings indicate the need for practical and robust tech- niques to appraise determinants of site use by snow leo- pards, especially in the context of the limited resources available for such work.

Title How Snow Leopards Share the Same Landscape with Tibetan Agro-pastoral Communities in the Chinese Himalayas Type Journal Article
Year 2022 Publication Journal of Resources and Ecology Abbreviated Journal
Volume 13 Issue 3 Pages 483-500
Keywords habitat use; landscape ecology; occupancy model; Qomolangma; Panthera uncia
Abstract The snow leopard (Panthera uncia) inhabits a human-altered alpine landscape and is often tolerated by residents in regions where the dominant religion is Tibetan Buddhism, including in Qomolangma NNR on the northern side of the Chinese Himalayas. Despite these positive attitudes, many decades of rapid economic development and population growth can cause increasing disturbance to the snow leopards, altering their habitat use patterns and ultimately impacting their conservation. We adopted a dynamic landscape ecology perspective and used multi-scale technique and occupancy model to better understand snow leopard habitat use and coexistence with humans in an 825 km2 communal landscape. We ranked eight hypothetical models containing potential natural and anthropogenic drivers of habitat use and compared them between summer and winter seasons within a year. HABITAT was the optimal model in winter, whereas ANTHROPOGENIC INFLUENCE was the top ranking in summer (AICcw≤2). Overall, model performance was better in the winter than in the summer, suggesting that perhaps some latent summer covariates were not measured. Among the individual variables, terrain ruggedness strongly affected snow leopard habitat use in the winter, but not in the summer. Univariate modeling suggested snow leopards prefer to use rugged land in winter with a broad scale (4000 m focal radius) but with a lesser scale in summer (30 m); Snow leopards preferred habitat with a slope of 22° at a scale of 1000 m throughout both seasons, which is possibly correlated with prey occurrence. Furthermore, all covariates mentioned above showed inextricable ties with human activities (presence of settlements and grazing intensity). Our findings show that multiple sources of anthropogenic activity have complex connections with snow leopard habitat use, even under low human density when anthropogenic activities are sparsely distributed across a vast landscape. This study is also valuable for habitat use research in the future, especially regarding covariate selection for finite sample sizes in inaccessible terrain.

Title Preliminary results of a long-term study of snow leopards in South Gobi, Mongolia Type Journal Article
Year 2010 Publication Cat News Abbreviated Journal
Volume Autumn Issue 53 Pages 15-19
Keywords snow leopard, Mongolia, monitor, population, Panthera, Snow Leopard Trust, Snow Leopard Conservation Fund, South Gobi, ecology, radio collar, GPS-satellite collar, home range, camera trapping, fecal genetics, occupancy modeling
Abstract Snow leopards Panthera uncia are under threat across their range and require urgent conservation actions based on sound science. However, their remote habitat and cryptic nature make them inherently difficult to study and past attempts have provided insufficient information upon which to base effective conservation. Further, there has been no statistically-reliable and cost-effective method available to monitor snow leopard populations, focus conservation effort on key populations, or assess conservation impacts. To address these multiple information needs, Panthera, Snow Leopard Trust, and Snow Leopard Conservation Fund, launched an ambitious long-term study in Mongolia’s South Gobi province in 2008. To date, 10 snow leo-pards have been fitted with GPS-satellite collars to provide information on basic snow leopard ecology. Using 2,443 locations we calculated MCP home ranges of 150 – 938 km2, with substantial overlap between individuals. Exploratory movements outside typical snow leopard habitat have been observed. Trials of camera trapping, fecal genetics, and occupancy modeling, have been completed. Each method ex-hibits promise, and limitations, as potential monitoring tools for this elusive species.

Title Status assessment of the Endangered snow leopard Panthera uncia and other large mammals in the Kyrgyz Alay, using community knowledge corrected for imperfect detection Type Journal Article
Year 2015 Publication Fauna & Flora International Abbreviated Journal
Volume Issue Pages 1-11
Keywords Capra sibirica, local knowledge, Lynx lynx, occupancy modelling, Ovis ammon polii, Panthera uncia, Ursus arctos
Abstract The Endangered snow leopard Panthera uncia occurs

in the Central Asian Mountains, which cover c.  million

km. Little is known about its status in the Kyrgyz Alay

Mountains, a relatively narrow stretch of habitat connecting

the southern and northern global ranges of the species. In

 we gathered information on current and past (,

the last year of the Soviet Union) distributions of snow leopards

and five sympatric large mammals across , km

of the Kyrgyz Alay.We interviewed  key informants from

local communities. Across  -km grid cells we obtained

, and  records of species occurrence (site

use) in  and , respectively. The data were analysed

using themulti-season site occupancy framework to incorporate

uncertainty in detection across interviewees and time

periods. High probability of use by snow leopards in the past

was recorded in .% of the Kyrgyz Alay. Between the two

sampling periods % of sites showed a high probability of

local extinction of snow leopard. We also recorded high

probability of local extinction of brown bear Ursus arctos

(% of sites) and Marco Polo sheep Ovis ammon polii

(% of sites), mainly in regions used intensively by people.

Data indicated a high probability of local colonization by

lynx Lynx lynx in % of the sites. Although wildlife has

declined in areas of central and eastern Alay, regions in

the north-west, and the northern and southern fringes

appear to retain high conservation value.
