Jackson, R., Roe, J., Wangchuk, R., & Hunter, D. (2005). Surveying Snow Leopard Populations with Emphasis on Camera Trapping: A Handbook. Sonoma, California: The Snow Leopard Conservancy.
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.

Abstract: The authors investigated livestock depredation patterns of snow leopards on the northern slopes of the Himalayans near the villages of Manang and Khangshar, Nepal. Information is discussed on the relationships among livestock loss, endangered species management, public relations/conservation issues, and cooperative efforts among institutions involved in the decision making process. A plan is devised for alleviating livestock loss and protecting endangered species in the area. pcp

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.

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: 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.

Mallon, D. P., Jackson, R. M. (2017). A downlist is not a demotion: Red List status and reality. Oryx, , 1–5.
Abstract: Assessments of biodiversity status are needed to
track trends, and the IUCN Red List has become the accepted
global standard for documenting the extinction
risk of species. Obtaining robust data on population size is
an essential component of any assessment of a species� status,
including assessments for the IUCN Red List. Obtaining
such estimates is complicated by methodological and
logistical issues, which are more pronounced in the case of
cryptic species, such as the snow leopard Panthera uncia.
Estimates of the total population size of this species have,
to date, been based on little more than guesstimates, but a
comprehensive summary of recent field research indicates
that the conservation status of the snow leopard may be
less dire than previously thought. A revised categorization,
from Endangered to Vulnerable, on the IUCN Red List was
proposed but met some opposition, as did a recent, similar
recategorization of the giant panda Ailuropoda melanoleuca.
Possible factors motivating such attitudes are discussed.
Downlisting on the IUCN Red List indicates that the species
concerned is further from extinction, and is always to be
welcomed, whether resulting from successful conservation
intervention or improved knowledge of status and trends.
Celebrating success is important to reinforce the message
that conservation works, and to incentivize donors.

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.
The following paragraphs summarize our accomplishments to date, supported by this grant. For detailed information, please consult the following reports, which are being mailed under separate cover:

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. (2002). Snow Leopard Status, Distribution, and Protected Areas Coverage.. Islt: Islt.
Abstract: This document reports on the status, distribution and protected areas coverage for snow leopard across its range in Central Asia. It is intended to aid in updating the existing knowledge base of snow leopard status and distribution during the Snow Leopard Survival Strategy (SLSS) Workshop organized by the International Snow Leopard Trust (ISLT), and to be held in Seattle on May 21-25, 2002. The SLSS workshop provides an unique opportunity to solicit feedback from scientists,
conservation organizations, government agencies and knowledgeable experts in order to:
(1) Verify the accuracy of information presented in this document (much of which was published 5-10 years ago) and to identify data gaps, especially with respect to population size and protectedareas coverage for this species;
(2) Aid organizations in developing tightly targeting conservation actions by identifying critical snow leopard areas, parks and reserves, and by implication, the intervening linking corridors linking key protected areas;
(3) Serve as a catalyst for encouraging range-countries to conduct field surveys into snow leopard status and distribution, especially in those areas deemed the most important to the maintenance of a viable metapopulation across the 12 countries in which the species' occurs.
