Abstract |
The snow leopard (Panthera uncia) and blue sheep (Pseudois nayaur) are the inhabitants of remote areas at higher altitudes with extreme geographic and climatic conditions. The habitats of these least-studied species are crucial for sustaining the Himalayan ecosystem. We employed the Maximum Entropy (MaxEnt) species distribution model to predict the potential habitat suitability of snow leopards and blue sheep and extracted common overlapped niches. For this, we utilised presence location, bio-climatic and environmental variables, and correlation analysis was applied to reduce the negative impact of multicollinearity. A total of 134 presence locations of snow leopards and 64 for blue sheep were selected from the Global Biodiversity Information Facility (GBIF). The annual mean temperature (Bio1) was found to be the most useful and highly influential factor to predict the potential habitat suitability of snow leopards. Annual mean temperature, annual precipitation and isothermality were the major influencing factors for blue sheep habitat suitability. Highly influential bio-climatic, topographic and environmental variables were integrated to construct the model for predicting habitat suitability. The area under the curve (AUC) values for snow leopard (0.87) and blue sheep (0.82) showed that the models are under good representation. Of the total area investigated, 47% was suitable for the blue sheep and 38% for the snow leopards. Spatial habitat assessment revealed that nearly 11% area from the predicted suitable habitat class of both species was spatially matched (overlapped), 48.6% area was unsuitable under niche overlap and 40.5% area was spatially mismatched niche. The presence of snow leopards and blue sheep in some highly suitable areas was not observed, yet such areas have the potential to sustain these elusive species. The other geographical regions interested in exploring habitat suitability may find the methodological framework adopted in this study useful for formulating an effective conservation policy and management strategy. |

Abstract |
The snow leopard (Panthera uncia) is a flagship species for conservation in the high mountain regions of central Asia. Data on snow leopard predation, habitat conditions and range of main prey species were gathered along with thematic maps of the study area for elevation, snow cover, sighting data, kill data, blue sheep use areas, and vegetation data. These data were entered into a GIS and used to help delineate surface features from a satellite image. Preliminary results show that general physiographic features of snow leopard habitat can be detected using satellite imagery and that GIS cartographic modeling techniques can improve this delineation. -from Authors |

Abstract |
The Disappearance of traditional ungulate prey of the snow leopard may be contributing to its endangered status in the wild. Soviet biologists have noted that wild sheep are a primary prey of the snow leopard in the southern Russian union republic and the Central Asian union republic of the U.S.S.R. While poaching appears to have had some impact on the status of these sheep, econmic pressures may be contributing to their decrease. Evidence presented for KAzakhstan and three regions of the Russian republic demonstrates that commercial sheep and goat production appears to be growing at a very high pace in these areas, thus consumming habitat otherwise available for wild herds. |

Abstract |
During November 1985 through July1996, a survey of snow leopard presence and ecology was conducted in selected areas of the states of Jammu and Kashmir, Himachal Pradesh, and Uttar Pradesh in north-western India. The study was carried out under the auspices of the Wildlife Institute of India in cooperation with the U.S. Fish and Wildlife Service and the International Snow Leopard Trust. The objectives of the survey were essentially determine the relative presence of the snow leopard and its associated prey species,investigate human interaction with the snow leopard and select an appropriate site for more intensive studies of the snow leopard and its ecosystem. |

Abstract |
A detailed knowledge of the ecology of a species is fundemental to the drawing up of effective conservation measures. One aim of the current project was to identify good areas of snow leopard habitatand evaluate them for possible inclusion in the Protected Area Network. Several good areas were surveyed and an outstanding area identified, and included in a report to the Chief Wildlife Warden. |

Abstract |
This program was drawn up at the invitation of the Chief Wildlife Warden of the State of Jammu and Kashmir, Mir Inayat Ullah, following joint survey work and discussions held over the period 1980-86. The recomendations have been accepted and will be incorporated into Department of Wildlife Protection policy. The aim of the program is the long term conservation of the snow leopard on a self sustaining basis throughout the state. Two basic assumptions underlie the program: (1) The snow leopard cannot be protected in isolation, but only in the context of conservation of the environment as a whole, and (2) To be most effective, any long term plan needs the cooperation of local people and must take into account their needs and traditional rights. |
