| Abstract | This study presents the testing of two unsupervised classification methods for their ability to accurately identify unknown individual tigers, Panthera tigris, and snow leopards, Panthera uncia, from their footprints. A neural-network based method, the Kohonen self-organizing map (SOM), and a Bayesian method, AutoClass, were assessed using hind footprints taken from captive animals under standardized conditions. AutoClass successfully discriminated individuals of both species from their footprints. Classification accuracy was greatest for tigers, with more misclassification of individuals occurring for snow leopards. Examination of variable influence on class formations failed to identify consistently influential measurements for either species. The self-organizing map did not provide accurate classification of individuals for either species. Results were not substantially improved by altering map dimensions nor by using principal components derived from the original data. The interpretation of resulting classifications and the importance of using such techniques in the study of wild animal populations are discussed. The need for further testing in the field is highlighted. | ||||

| Title | How Snow Leopards Share the Same Landscape with Tibetan Agro-pastoral Communities in the Chinese Himalayas | Type | Journal Article | ||

| 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. | ||||

| Abstract | China may hold a greater proportion of the global snow leopard Panthera uncia population than any other country, with the area of good quality suitable habitat, estimated at nearly 300,000 km2, comprising .50% of that available across the species' entire range. We can now reconfirm the presence of snow leopard in the Taxkurgan area of Xinjiang Province in north-west China after a period of 20 years. | ||||

| Title | Human wildlife conflict involving large carnivores in Qilianshan, China and the minimal paw-print of snow leopards | Type | Journal Article | ||

| Abstract | In this paper, we assess local perceptions towards snow leopards in North West China using a framework depicting key conflict domains. We describe the perceived threats posed to humans by the snow leopard and set them within beliefs and attitudes towards other species within the large carnivore assemblage in this region. Surveys were conducted in seven villages within Qilianshan National Nature Reserve, Gansu Province, China, to document reports of snow leopard (Panthera uncia), grey wolf (Canis lupus), Eurasian lynx (Lynx lynx) and brown bear (Ursus arctos) depredation of livestock, and local attitudes towards each species. Questionnaire-based interviews were held with 60 households and 49 livestock herders. Herding of yak, sheep and goats was found to be a common livelihood activity among households in all villages. Herders reported losing livestock to all four carnivore species. Herders reported that depredation was the most common event affecting livestock, compared with natural disasters or disease, and represented a total loss of 3.6% of the livestock population during the previous year. Most (53%) depredation losses were attributed to lynx, while snow leopards were held responsible for only 7.8% of depredation losses. The reported impact of snow leopards on herding activities was relatively small and the majority of both householders and herders expressed positive attitudes towards them and supported measures for their protection. Households and herders held negative attitudes towards lynx, wolves and bears, however, most likely due to their perceived threat to livestock and humans. Understanding community perceptions of threats posed by wildlife is vital for gaining community support for, and engagement in, conflict mitigation. |
