Abstract: We provide body measurements of snow leopards collected from 55 individuals sampled in five of the major mountain ranges within the species distribution range; the Altai, Hindu Kush, Himalayas, Pamirs and Tien Shan mountains. Snow leopards appear to be similarly sized across their distribution range with mean body masses of 36 kg and 42 kg for adult females and adult males, respectively. In contrast to other large felids, we found little variation in body size and body mass between the sexes; adult males were on average 5% longer and 15% heavier than adult females.

Abstract: This study was undertaken in spring, 2019 to assess the applicability of the double-observer survey method for estimating blue sheep Pseudois nayaur abundance in Nar-Phu valley of Manang District located in Annapurna Conservation Area of northern Nepal. Since counting large mammals in rugged mountain habitat poses a special challenge, we tested the efficacy of the double observer method for generating robust population estimates for this important protected area. The overall detection probability for observers (O1 and O2) was 0.94 and 0.91 for a total of 106 groups comprised of 2059 individual blue sheep. We estimated the area’s blue sheep population at 2070 (SE ± 168.77; 95% CI 2059–2405) for the 246.2 km2 of sampled habitat. We determined blue sheep to be widely distributed within the study area with a mean density of 8.4 individuals per km2 based on a total study area of 246.2 km2. We discuss demographic population structure and identify limitations when applying the double observer approach, along with recommending viewshed mapping for ensuring more robust density estimates of mountain-dwelling ungulates like blue sheep or ibex that inhabit extremely heterogeneous terrain which strongly influences sighting distances and overall animal detection rates.

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.

Genetic diversity and spatial structures of snow leopards (Panthera uncia) reveal proxies of connectivity across Mongolia and northwestern China. Landscape Ecology, , 1–19.
Abstract: Understanding landscape connectivity and population genetic parameters is imperative for threatened species management. However, such information is lacking for the snow leopard (Panthera uncia). This study sought to explore hierarchical snow leopard gene flow patterns and drivers of genetic structure in Mongolia and China. A total of 97 individuals from across Mongolia and from the north-eastern edge of the Qinghai-Tibetan Plateau in Gansu Province to the middle of Qinghai Province in China were genotyped across 24 microsatellite loci. Distance-based frameworks were used to determine a landscape scenario best explaining observed genetic structure. Spatial and non-spatial methods were used to investigate fine-scale autocorrelation and similarity patterns as well as genetic structure and admixture. A genetic macro-division between populations in China and Mongolia was observed, suggesting that the Gobi Desert is a substantial barrier to gene flow. However, admixture and support for a resistance-based mode of isolation suggests connective routes that could facilitate movement. Populations in Mongolia had greater connectivity, indicative of more continuous habitat. Drivers of genetic structure in China were difficult to discern, and fine-scale sampling is needed. This study elucidates snow leopard landscape connectivity and helps to prioritize conservation areas. Although contact zones may have existed and occasional crossings can occur, establishing corridors to connect these areas should not be a priority. Focus should be placed on maintaining the relatively high connectivity for snow leopard populations within Mongolia and increasing research efforts in China.

Abstract: Preliminary recommendations for the management of snow leopard and its prey are provided for the Langu Valley segment of the Shey-Pkoksundo National Park. Park-wide and country-wide conservation options and management recommendations await results of the surveys scheduled for 1987. The following management objectives are formulated: 1) Protection and ultimate restoration of all natural communities within the area 2) Special protection measures for snow leopard and musk deer (strict control of hunting and livestock grazing) 3) Secure natural resources around local villages 4) Respect traditional rights of villagers, while controlling high impact human activities 5) Secure cooperation of local people. These objectives are refined and recommendations for concrete conservation actions are made.

Jackson, R., Roe, J., Wangchuk, R., & Hunter, D. (2006). Estimating Snow Leopard Population Abundance Using Photography and Capture-Recapture Techniques (Vol. 34).
Abstract: Conservation and management of snow leopards (Uncia uncial) has largely relied on anecdotal evidence and presence-absence data due to their cryptic nature and the difficult terrain they inhabit. These methods generally lack the scientific rigor necessary to accurately estimate population size and monitor trends. We evaluated the use of photography in capture-mark-recapture (CMR) techniques for estimating snow leopard population abundance and density within Hemis National Park, Ladakh, India. We placed infrared camera traps along actively used travel paths, scent-sprayed rocks, and scrape sites within 16-30 kmý sampling grids in successive winters during January and March 2003-2004. We used head-on, oblique, and side-view camera configurations to obtain snow leopard photographs at varying body orientations. We calculated snow leopard abundance estimates using the program CAPTURE. We obtained a total of 66 and 49 snow leopard captures resulting in 8.91 and 5.63 individuals per 100 trap nights during 2003 and 2004, respectively. We identified snow leopards based on the distinct pelage patters located primarily on the forelimbs, flanks, and dorsal surface of the tail. Capture probabilities ranged from 0.33 to 0.67. Density estimates ranged from 8.49 (SE+0.22) individuals per 100 kmý in 2003 to 4.45 (SE+0.16) in 2004. We believe the density disparity between years is attributable to different trap density and placement rather than to an actual decline in population size. Our results suggest that photographic capture-mark-recapture sampling may be a useful tool for monitoring demographic patterns. However, we believe a larger sample size would be necessary for generating a statistically robust estimate of population density and abundance based on CMR models.

Abstract: The endangered snow leopard (Panthera uncia) is widely but sparsely distributed throughout the mountainous regions of central Asia. Detailed information on the status and abundance of the snow leopard is limited because of the logistical challenges faced when working in the rugged terrain it occupies, along with its secretive nature. Camera-trapping and noninvasive genetic techniques have been used successfully to survey this felid. We compared noninvasive genetic and camera-trapping snow leopard surveys in the Gobi Desert of Mongolia. We collected 180 putative snow leopard scats from 3 sites during an 8-day period along 37.74 km of transects. We then conducted a 65-day photographic survey at 1 of these sites, approximately 2 months after scat collection. In the site where both techniques were used noninvasive genetics detected 5 individuals in only 2 days of fieldwork compared to 7 individuals observed in the 65-day camera-trapping session. Estimates of population size from noninvasive genetics ranged between 16 and 19 snow leopards in the 314.3-km2 area surveyed, yielding densities of 4.9–5.9 individuals/100 km2. In comparison, the population estimate from the 65-day photographic survey was 4 individuals (adults only) within the 264-km2 area, for a density estimate of 1.5 snow leopards/100 km2. Higher density estimates from the noninvasive genetic survey were due partly to an inability to determine age and exclude subadults, reduced spatial distribution of sampling points as a consequence of collecting scats along linear transects, and deposition of scats by multiple snow leopards on common sites. Resulting differences could inflate abundance estimated from noninvasive genetic surveys and prevent direct comparison of densities derived from the 2 approaches unless appropriate adjustments are made to the study design.

Abstract: A survey was undertaken of selected parts of Sagarmatha National Park to determine whether snow leopard was present, using techniques developed during a recent in-depth study of the species in west Nepal, using radio-telemetry. Although the species was considered to have been extirpated from the park in the 1970's, occasional reports have originated from trekkers who reported “seeing a snow leopard near Mount Everest (Sagarmatha)”.

Jackson, R., Hillard, D. (2003). Non-invasive Monitoring to Support Local Stewardship of Snow Leopards and Their Prey: Annual progress report summary.
Abstract: Under this grant awarded by The Leonard X. Bosack and Bette M. Kruger Foundation through the auspices of Cat Action Treasury, SLC set out to accomplish the following outcomes in our Stewardship Program:
As of July 1, 2003 we completed the following major activities:
* Tested and compared different remote sensor and camera configurations to determine which is most reliable at “capturing” passing snow leopards;
* Investigated sampling strategies and camera trap placement with respect to snow leopard travel patterns and marking behavior;
* Compared different survey methods: direct (non-invasive capture of photos and DNA material contained in hairs), and indirect (sign transects and presence/absence surveys under the standard SLIMS protocol);
* Assessed the attitude of local people toward snow leopards, wolves and other wildlife as well as their perceptions of benefits and costs associated with the Hemis National Park, in order to craft more effective conservation and park management measures.
These activities mesh with SLC’s ongoing program of predator-proofing livestock corrals in settlements of the Hemis National Park, as well as outside protected areas (including Zanskar, Lingshed and Kanji. For each village’s corrals that are improved, we estimate that five or more snow leopards are saved from retaliatory killing by shepherds who lose valuable livestock.
Our program in assisting villagers to gain supplementary income from tourism-related activities is gaining strength, with trainings in 10 settlements this spring. SLC brought staff of KCC, the Khangchenjunga Conservation Committee, a local NGO based in Sikkim to assist in the skills training and to exchange ideas and experiences from other areas.
Following on from the groundwork laid during the first Bosack-Kruger grant to SLC, we launched a major initiative in collaboration with the Mountain Institute, the Himalayan Homestay program. Funding for this is being provided by UNESCO.
For further information on these and other snow leopard conservation efforts, see our newly designed web-page.

Jackson, R., Wangchuk, R. (2001). Linking Snow Leopard Conservation and People-Wildlife Conflict Resolution: Grassroots Measures to Protect the Endangered Snow Leopard from Herder Retribution. Endangered Species UPDATE, 18(4), 138–141.
Abstract: Livestock depredation has become a significant problem across the snow leopard's (Panthera uncia) range in Central Asia, being most severe in and near protected areas. Such predation, especially incidents of “surplus killing,” in which five to 100 or more sheep and goats are lost in a single night, almost inevitably leads herders to retaliate by killing rare or endangered carnivores like snow leopard, wolf, and lynx. Ironically, such loss can be avoided by making the night-time enclosures predator-proof, improving animal husbandry techniques, educating herders on wildlife conservation and the importance of protecting the natural prey base, and by providing economic incentives like handicrafts skills training and marketing, along with carefully planned ecotourism trekking and guiding. The author explores innovative conservation initiatives in the Himalaya (Ladakh and Tibet) and Mongolia, which also build local capacity, self-reliance, and stewardship for nature using Appreciative Participatory Planning and Action, or APPA, techniques. The most sound conservation investments are those contingent upon establishing direct linkages with biodiversity protection, ensuring co-financing and reciprocal responsibility for project activities, encouraging the full participation of all stakeholders, and assuring regular monitoring and evaluation of the village-based agreements (embodied in Action Plans).

Jackson, R., Hillard, D. (2002). The Snow Leopard Conservancy Year-end report 2002.
Abstract: While the SLC is just two years old, our twenty years of field experience, numerous contacts and well-established professional relationships have enabled us to work as a mature organization. The Wildlife Conservation Network (WCN) has been instrumental in building awareness of the SLC within the community, and in raising $85,000 in individual donations and merchandise sales which comprised 46% of our 2002 operating budget. With our overhead costs kept to a minimum and being substantially underwritten, donor dollars can be used directly and effectively in the field. With our donors and volunteers committed to helping us build our sustainability, we look forward to even greater success in saving snow leopards in partnership with local people.

Jackson, R., Wangchuk, R. (2000). People-wildlife conflicts in the trans-Himalaya. (pp. 1–10).
Abstract: Wildlife-related crop and livestock damage is emerging as a leading source of conflict between local communities, protected areas and park managers throughout India and the Himalayan region (Kharel 1997, Mishra 1997, Saberwal et al. 1994 and Sekhar 1998). For example, a comprehensive household-level survey of herders living in Nepal’s Annapurna Conservation Area suggested that predation accounted for 63% of all livestock mortality over a 18-24 month period, mostly attributable to snow leopard (Jackson et al. 1996). Oli et al. (1994) reported the predation rate at 2.6% of the stockholding, with losses representing as much as 25% of the average household’s per capita income. Hardly surprisingly, most local people held strongly negative attitudes toward snow leopard and wolf. In the Kibber Wildlife Sanctuary in Lahaul-Spiti, Mishra (1997) reported that 18% of the livestock holding were killed over a 18 month period, amounting to 1.6 animals per household perannum, with an estimated total value of US $ 128 per family per year. Villages received compensationin only 28 of 131 reported cases. According to local residents, predation rates in the sanctuary had increased markedly since its establishment. Mishra (1997) attributes this to a dramatic increase in livestock numbers accompanying a shift rom subsistence to a more commercially-based animal husbandry pattern.
The purpose of this presentation is to provide an overview of livestock damage from wild carnivores and how protected area managers could best approach this contentious issue. The author uses Hemis National Park as a case study example, focusing on baseline information gathering, and past, current and proposed remedial actions for reducing losses and compensating livestock owners.
