Title Vigorous Dynamics Underlie a Stable Population of the Endangered Snow Leopard Panthera uncia in Tost Mountains, South Gobi, Mongolia Type Journal Article
Year 2014 Publication Plos One Abbreviated Journal
Volume 9 Issue 7 Pages
Keywords
Abstract Population monitoring programmes and estimation of vital rates are key to understanding the mechanisms of population growth, decline or stability, and are important for effective conservation action. We report, for the first time, the population trends and vital rates of the endangered snow leopard based on camera trapping over four years in the Tost Mountains, South Gobi, Mongolia. We used robust design multi-season mark-recapture analysis to estimate the trends in abundance, sex ratio, survival probability and the probability of temporary emigration and immigration for adult and young snow leopards. The snow leopard population remained constant over most of the study period, with no apparent growth (l = 1.08+20.25). Comparison of model results with the ‘‘known population’’ of radio-collared snow leopards suggested

high accuracy in our estimates. Although seemingly stable, vigorous underlying dynamics were evident in this population, with the adult sex ratio shifting from being male-biased to female-biased (1.67 to 0.38 males per female) during the study. Adult survival probability was 0.82 (SE+20.08) and that of young was 0.83 (SE+20.15) and 0.77 (SE +20.2) respectively, before and after the age of 2 years. Young snow leopards showed a high probability of temporary emigration and immigration (0.6, SE +20.19 and 0.68, SE +20.32 before and after the age of 2 years) though not the adults (0.02 SE+20.07). While the current female-bias in the population and the number of cubs born each year seemingly render the study population safe, the vigorous dynamics suggests that the situation can change quickly. The reduction in the proportion of

male snow leopards may be indicative of continuing anthropogenic pressures. Our work reiterates the importance of monitoring both the abundance and population dynamics of species for effective conservation.

Title Snow Leopards and Telemetry: Experiences and Challenges Type Journal Article
Year 2010 Publication Telemetry in Wildlife Science Abbreviated Journal
Volume 13 Issue No. 1 Pages 1 -5
Keywords Snow Leopards, telemetry
Abstract The snow leopard Panthera uncia is one of the least studied felids in the world. Little is know about various aspects of the ecology of the snow leopard, which is cryptic in nature and found across 12 countries in Central Asia. Most research on snow leopards has been based on non-invasive methods such as sign surveys for presence (e.g. Jackson and Hunter 1996), scat analyses for diet (e.g. Chundawat and Rawat 1992; Oli et al., 2008, 2010) for population estimation, and studies based on human interviews (Mehta and Heinen 2001; Mishra and Bagchi 2006).

Despite this plethora of studies employing non-invasive techniques, several crucial questions about snow leopard ecology remain unanswered. Information about the animal’s home range, dispersal, corridors, pattern of habitat use, movement patterns, hunting frequency, behavior and intra – specific interactions is not available yet. In order to design population monitoring studies using camera traps or DNA analyses, one needs a good understanding of snow leopard ecology, including the home range and movement patterns (Williams et al., 2002). Telemetry is still the best available method and perhaps much less invasive than direct observations for studying the biology and ecology of cryptic animals.

Title Does livestock benefit or harm snow leopards? Type Journal Article
Year 201 Publication Biological Conservatio Abbreviated Journal
Volume Issue 190 Pages 8-13
Keywords Panthera uncia, Trans-Himalaya, Pastoralism, Large carnivores, Livestock grazing, Co-existence
Abstract Large carnivores commonly prey on livestock when their ranges overlap. Pastoralism is the dominant land use type across the distributional range of the endangered snow leopard Panthera uncia. Snow leop- ards are often killed in retaliation against livestock depredation. Whether livestock, by forming an alter- native prey, could potentially benefit snow leopards, or, whether livestock use of an area is detrimental to snow leopards is poorly understood. We examined snow leopard habitat use in a multiple use landscape that was comprised of sites varying in livestock abundance, wild prey abundance and human population size. We photographically sampled ten sites (average size 70 sq. km) using ten camera traps in each site, deployed for a period of 60 days. Snow leopard habitat use was computed as a Relative Use Index based on the total independent photographic captures and the number of snow leopard individuals captured at each site. We quantified livestock abundance, wild prey abundance, human population size and terrain ruggedness in each of the sites. Key variables influencing snow leopard habitat use were identified using Information Theory based model selection approach. Snow leopard habitat use was best explained by wild prey density, and showed a positive linear relationship with the abundance of wild ungulates. We found a hump-shaped relationship between snow leopard habitat use and livestock stocking density, with an initial increase in habitat use followed by a decline beyond a threshold of livestock density. Our results suggest that in the absence of direct persecution of snow leopards, livestock grazing and snow leopard habitat use are potentially compatible up to a certain threshold of livestock density, beyond which habitat use declines, presumably due to depressed wild ungulate abundance and associated anthropogenic disturbance.

Title Prey Preference of Snow Leopard (Panthera Uncia) in South Gobi, Mongolia Type Journal Article
Year 2012 Publication PLoS ONE Abbreviated Journal
Volume Issue Feb 2012 Pages
Keywords
Abstract Accurate information about the diet of large carnivores that are elusive and inhabit inaccessible terrain, is required to properly design conservation strategies. Predation on livestock and retaliatory killing of predators have become serious issues throughout the range of the snow leopard. These techniques have inherent limitation in their ability to properly identify both snow leopard feces and prey taxa, To examine the frequency of livestock prey and and nearly-threatened argali in the diet of the snow leopard, we employed the recently developed DNA-based diet approach to study a snow leopard population located in the Tost Mountains, South Gobi, Mongolia. After DNA was extracted from the feces, a region of ~100 bp long from mitochondrial 12S rRNA gene was amplified, making use of universal primers for vertebrates and a blocking oligonucleotide specific to snow leopard DNA. The amplicons were then sequenced using a next-generation sequencing platform. We observed a total of five different prey items from 81 fecal samples. Siberian ibex predominated the diet (in 70.4% of the feces), followed by domestic goat (17.3%) and argali sheep (8.6%). The major part of the diet was comprised of large ungulates (in 98.8% of the feces) including wild ungulates (79%) and domestic livestock (19.7%). The findings of the present study will help to understand the feeding ecology of the snow leopard, as well as to address the conservation and management issues pertaining to this wild cat.

Title Cats, canines, and coexistence: dietary differentiation between the sympatric Snow Leopard and Grey Wolf in the western landscape of Nepal Himalaya Type Journal Article
Year 2019 Publication Journal of Threatened Taxa Abbreviated Journal
Volume 11 Issue 7 Pages 13815-13821
Keywords Canis lupus, dietary pattern, dietary overlap, livestock, Naur, negative interaction, Panthera uncia, scat analysis, sympatry
Abstract Understanding the dietary habits of sympatric apex carnivores advances our knowledge of ecological processes and aids their conservation. We compared the diets of the sympatric Snow Leopard Panthera uncia and Grey Wolf Canis lupus using standard micro-histological analyses of scats collected from the western complex of Nepal Himalaya. Our study revealed one of the highest recorded contributions of livestock to the diet of top predators (55% for Grey Wolf and 39% for Snow Leopard) and high dietary overlap (0.82) indicating potential exploitative or interference competition. Their diet composition, however, varied significantly based on their consumption of wild and domestic prey. Limitation in data precludes predicting direction and outcome of inter-specific interactions between these predators. Our findings suggest a high rate of negative interaction with humans in the region and plausibly retaliatory killings of these imperilled predators. To ensure the sustained survival of these two apex carnivores, conservation measures should enhance populations of their wild prey species while reducing livestock losses of the local community through preventive and mitigative interventions.

Title Diet and prey selection by snow leopards in the Nepalese Himalayas Type Journal Article
Year 2018 Publication PLoS ONE Abbreviated Journal
Volume Issue Pages 1-18
Keywords
Abstract Visual attractiveness and rarity often results in large carnivores being adopted as flagship

species for stimulating conservation awareness. Their hunting behaviour and prey selection

can affect the population dynamics of their prey, which in turn affects the population dynamics

of these large carnivores. Therefore, our understanding of their trophic ecology and foraging

strategies is important for predicting their population dynamics and consequently for

developing effective conservation programs. Here we concentrate on an endangered species

of carnivores, the snow leopard, in the Himalayas. Most previous studies on snow leopard

diet lack information on prey availability and/or did not genetically check, whether the

identification of snow leopard scats is correct, as their scats are similar to those of other

carnivores. We studied the prey of snow leopard in three Himalayan regions in Nepal

(Sagarmatha National Park (SNP), Lower Mustang (LM) and Upper Manang (UM) in the

Annapurna Conservation Area, during winter and summer in 2014&#65533;2016. We collected 268

scats along 139.3 km linear transects, of which 122 were genetically confirmed to belong to

snow leopard. Their diet was identified by comparing hairs in scats with our reference collection

of the hairs of potential prey. We determined prey availability using 32&#65533;48 camera-traps

and 4,567 trap nights. In the SNP, the most frequent prey in snow leopard faeces was the

Himalayan tahr in both winter and summer. In LM and UM, its main prey was blue sheep in

winter, but yak and goat in summer. In terms of relative biomass consumed, yak was the

main prey everywhere in both seasons. Snow leopard preferred large prey and avoided

small prey in summer but not in winter, with regional differences. It preferred domestic to

wild prey only in winter, and in SNP. Unlike most other studies carried out in the same area,

our study uses genetic methods for identifying the source of the scat. Studies solely based

on visual identification of samples may be strongly biased. Diet studies based on frequency

of occurrence of prey tend to overestimate the importance of small prey, which may be consumed

more often, but contribute less energy than large prey. However, even assessments

based on prey biomass are unlikely to be accurate as we do not know whether the actual

size of the prey consumed corresponds to the average size used to calculate the biomass

eaten. For example, large adults may be too difficult to catch and therefore mostly young animals are consumed, whose weight is much lower. We show that snow leopard consumes

a diverse range of prey, which varies both regionally and seasonally. We conclude that in

order to conserve snow leopards it is also necessary to conserve its main wild species of

prey, which will reduce the incidence of losses of livestock.

Title Saving threatened species in Afghanistan: snow leopards in the Wakhan Corridor Type Journal Article
Year 2011 Publication International Journal of Environmental Studies Abbreviated Journal
Volume 68 Issue 3 Pages 299-312
Keywords Snow leopard; Camera trap; Governance; Rangers; Corral; Insurance
Abstract The Wakhan Corridor in northeast Afghanistan is an area known for relatively abundant wildlife and it appears to represent Afghanistan’s most important snow leopard landscape. The Wildlife Conservation Society (WCS) has been working in Wakhan since 2006. Recent camera trap surveys have documented the presence of snow leopards at 16 different locations in the landscape. These are the first camera trap records of snow leopards in Afghanistan. Threats to snow leopards in the region include the fur trade, retaliatory killing by shepherds and the capture of live animals for pets. WCS is developing an integrated management approach for this species, involving local governance, protection by a cadre of rangers, education, construction of predator-proof livestock corrals, a livestock insurance program, tourism and research activities. This management approach is expected to contribute significantly to the conservation of snow leopards and other wildlife species in the Wakhan.
