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 |
Livestock depredation by the endangered snow leopard (Panthera uncia) is an increasingly contentious issue in Himalayan villages, especially in or near protected areas. Mass attacks in which as many as 100 sheep and goats are killed in a single incident inevitably result in retaliation by local villagers. This article describes a community-based conservation initiative to address this problem in Hemis National Park, India. Human-wildlife conflict is alleviated by predator-proofing villagers' nighttime livestock pens and by enhancing household incomes in environmentally sensitive and culturally compatible ways. The authors have found that the highly participatory strategy described here (Appreciative Participatory Planning and Action-APPA) leads to a sense of project ownership by local stakeholders, communal empowerment, self-reliance, and willingness to co-exist with
snow leopards. The most significant conservation outcome of this process is the protection from retaliatory poaching of up to five snow leopards for every village's livestock pens that are made predator-proof. |

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). |

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 |
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 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 |
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 |
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. |
