Suryawanshi, K. R., Khanyari, M., Sharma, K., Lkhagvajav, P., Mishra, C. (2019). Sampling bias in snow leopard population estimation studies. Population Eccology, , 1–9.
Abstract: Accurate assessments of the status of threatened species and their conservation
planning require reliable estimation of their global populations and robust monitoring
of local population trends. We assessed the adequacy and suitability of studies
in reliably estimating the global snow leopard (Panthera uncia) population. We
compiled a dataset of all the peer-reviewed published literature on snow leopard
population estimation. Metadata analysis showed estimates of snow leopard density
to be a negative exponential function of area, suggesting that study areas have generally
been too small for accurate density estimation, and sampling has often been
biased towards the best habitats. Published studies are restricted to six of the
12 range countries, covering only 0.3�0.9% of the presumed global range of the
species. Re-sampling of camera trap data from a relatively large study site
(c.1684 km2) showed that small-sized study areas together with a bias towards
good quality habitats in existing studies may have overestimated densities by up to
five times. We conclude that current information is biased and inadequate for generating
a reliable global population estimate of snow leopards. To develop a rigorous
and useful baseline and to avoid pitfalls, there is an urgent need for
(a) refinement of sampling and analytical protocols for population estimation of
snow leopards (b) agreement and coordinated use of standardized sampling protocols
amongst researchers and governments across the range, and (c) sampling
larger and under-represented areas of the snow leopard's global range.

Abstract: A syndrome of multiple congenital ocular anomalies in a litter of domestic kittens is described which appears identical to the multiple colobomatous syndrome described in captive Snow Leopards. The lesions varied between kittens in the litter, but ranged from microphthalmos with blindness to mild alterations in the lateral lid margins that resulted in trichiasis. The syndrome of eyelid agenesis in the domestic cat may encompass a broad range of congenital ocular lesions and multiple siblings, but the cause and mechanism of lesion formation is unknown.

Jain, N., Wangchuk, R., & Jackson, R. (2003). An Assessment of CBT and Homestay Sites in Spiti District, Himachal Pradesh.
Abstract: The survey described in this report builds upon prior CBT activities undertaken by The Mountain Institute (TMI) in partnership with the Snow Leopard Conservancy (SLC) in Ladakh, supported by a grant from UNESCO (with co-financing from SLC). Under the evolving concept of “Himalayan Homestays”, initially developed and tested in Ladakh, it is proposed that activities be expanded to selected states in India in a strategic and effective way. Himalayan Homestays are part of a larger integrated program to link snow leopard conservation with local livelihoods in Asia.

Abstract: Understanding species distributions, patterns of
change and threats can form the basis for assessing the conservation
status of elusive species that are difficult to survey.
The snow leopard Panthera uncia is the top predator of the
Central and South Asian mountains. Knowledge of the distribution
and status of this elusive felid and its wild prey is
limited. Using recall-based key-informant interviews we estimated
site use by snow leopards and their primary wild
prey, blue sheep Pseudois nayaur and Asiatic ibex Capra
sibirica, across two time periods (past: �; recent:
�) in the state of Himachal Pradesh, India. We
also conducted a threat assessment for the recent period.
Probability of site use was similar across the two time periods
for snow leopards, blue sheep and ibex, whereas for wild
prey (blue sheep and ibex combined) overall there was an
% contraction. Although our surveys were conducted in
areas within the presumed distribution range of the snow
leopard, we found snow leopards were using only % of
the area (, km). Blue sheep and ibex had distinct distribution
ranges. Snow leopards and their wild prey were not
restricted to protected areas, which encompassed only %
of their distribution within the study area. Migratory livestock
grazing was pervasive across ibex distribution range
and was the most widespread and serious conservation
threat. Depredation by free-ranging dogs, and illegal hunting
and wildlife trade were the other severe threats. Our
results underscore the importance of community-based, landscape-
scale conservation approaches and caution against reliance
on geophysical and opinion-based distribution maps that have been used to estimate national and global snow leopard ranges.

Dementiev G.P. (1967). Quadrupeds inhabitants of the mountains.
Abstract: All species inhabiting the highlands of Asia are normally referred to as herbivorous or predators. A majority of alpine land species (rodents and ungulates) feeds upon leaves, stalks, and roots of plants. Among widely distributed highland species the most interesting are marmots, red pica, grey vole, argali, and ibex. Argali and ibex are preyed on by snow leopards. There are reasons to believe that these mountain animal species are more ancient than their cognates in a plain. All the way from Central Asia to Europe, species belonging to the eastern and western fauna complexes are observed to interpenetrate.

Abstract: A snow leopard project is underway to study snow leopards in Mongolia. The project, called the Mongolian-American Snow Leopard Project, involves the Wildlife Conservation Society, the Mongolian Association for the Conservation of Nature and Environment, the National Geographic Society, the Mongolian Ministry of Nature and the Environment, the U.S. National Biological Service, and the International Snow Leopard Trust. The objective of the study is to survey the distribution and status of Mongolia's snow leopards, including those living in the Gobi Desert. klf.

Fox, J. L. (1997). Conflict between predators and people in Ladakh. Cat News, 17, 18.
Abstract: During a six-week period in Hemis National Park, Ladakh, India, snow leopards killed 10 sheep and goats and one leopard gained access to a livestock pen and killed many of the animals inside. Dholes also killed sheep and goats, and a wolf killed a young horse. Residents routinely remove snow leopard cubs from their dens to limit future damage by this species. How to deal with the plight of the people living in the area while still protecting the endangered species are major concerns of the International Snow Leopard Trust, which manages Hemis National Park. lgh.
