Janeč, & ka, J. E., Munkhtsog, B., Jackson, R.M., Naranbaatar, G., Mallon, D.P. & Murphy, W.J. (2011). Comparison of noninvasive genetic and camera-trapping techniques for surveying snow leopards. Journal of Mammalogy, 92(4), 771–783.
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.

Ahlborn, G., Jackson, R. A survery of Sagarmatha National Park and the endangered Snow Leopard.
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.

Wangchuk, R., & Jackson, R. (2009). A Community-based Approach to Mitigating Livestock-Wildlife Conflict in Ladakh, India.
Abstract: Livestock depredation by snow leopard and wolf is widespread across the Himalayan region (Jackson et al. 1996, Jackson and Wangchuk 2001; Mishra 1997, Oli et al 1994). For example, in India's Kibber Wildlife Sanctuary, Mishra (1997) reported losses amounting to 18% of the livestock holdings and valued at about US $138 per household. The villagers claimed predation rates increased after establishment of the sanctuary, but
surveys indicated a dramatic increase in livestock numbers accompanying changes in animal husbandry systems (Mishra 2000).

Abstract: This handbook provides an introduction to snow leopard population survey techniques, followed by a detailed account of camera trapping methods.During the 2002 through 2004 winter field seasons, the Snow Leopard Conservancy experimented with infrared camera trapping techniques to define a methodology suitable for the high altitude environment.
In 2001 and 2002, much of our time was spent familiarizing ourselves with various infrared camera traps, their operation and setup, and comparing the effectiveness of different models and sensor types. We placed infrared camera traps along frequently used travel corridors at or near scent-sprayed rocks (rock scents) and scrape sites within 16 km2 sampling cells between January and March in 2003 and 2004. A total of 66 and 49 captures of snow leopards were tallied during 2003 and 2004, resulting in an overall capture success of 8.91 and 5.63 individuals per 100 trap-nights, respectively. Capture probabilities ranged from 0.33 to 0.46. Density estimates ranged from 8.49 ± 0.22 individuals per 100 km2 in 2003 to 4.45 ± 0.16 in 2004, with the disparity between years largely attributed to different trapping densities. Snow leopard abundance estimates were calculated using the computer program CAPTURE.

Jackson, R., Roe, J., Wangchuk, R., & Hunter, D. (2005). Camera-Trapping of Snow Leopards. Cat News, 42(Spring), 19–21.
Abstract: Solitary felids like tigers and snow leopards are notoriously difficult to enumerate, and indirect techniques like pugmark surveys often produce ambiguous information that is difficult to interpret because many factors influence marking behavior and frequency (Ahlborn & Jackson 1988). Considering the snow leopard's rugged habitat, it is not surprising then that information on its current status and occupied range is very limited. We adapted the camera-trapping techniques pioneered by Ullas Karanth and his associates for counting Bengal tigers to the census taking of snow leopards in the Rumbak watershed of the India's Hemis High Altitude National Park (HNP), located in Ladakh near Leh (76ø 50' to 77ø 45' East; 33ø 15' to 34ø 20'North).

Abstract: Livestock depredation is emerging as a significant issue across the Himalaya, including the Hemis National Park (HNP) in Ladakh. Some consider that this protected area harbors the best snow leopard population in India, but local herders perceive the endangered snow leopard as a serious threat to their livelihood.

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: In response to dwindling wildlife populations and habitat, governments established national parks and protected areas, often with little input from people living in the immediate area. In some cases communities were relocated, but in most they are left to pursue traditional agricultural and pastoral livelihoods under a new set of rules. Important questions of land tenure remained unresolved, with a “fences and fines” approach to protected area management (Stolton and Dudley 1999).
