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.

Abstract: Describes snow leopard status and field observations from studies in Pakistan and Nepal. Review provides some data on snow leopard marking behavior, social relations, food habits and predator behavior.

Abstract: The wildlife of temperate forest ecosystems in the Western Himalayas is threatened by destruction of habitat and hunting. Two species of pheasants occuring in the survey area (western tragopan Tragopan melanocephalus and cheer pheasant Catreus wallichi) are listed in the IUCN Red Data Book (1979). Small populations of both species were located and information on their habitat requirements was obtained. The status of most large mammal species appears to be precarious, with the populations encountered being small and fragmented. Species formerly common but now rare include Himalayan brown bear Ursus arctos, Himalayan tahr Hemitragus jemlahicus and musk deer Moschus moschiferus. The snow leopard Panthera uncia has disappeared completely from the area.-from Authors
