Ale S. (2005). Have snow leopards made a comeback to the Everest region of Nepal?.
Abstract: In the 1960s, the endangered snow leopard was locally extirpated from the Sagarmatha (Mt. Everest) region of Nepal. In this Sherpa-inhabited high Himalaya, the flourishing tourism since the ascent of Mt Everest in 1953, has caused both prosperity and adverse impacts, the concern that catalyzed the establishment of Mt. Everest National Park in the region in 1976. In the late 1980s, there were reports that some transient snow leopards may have visited the area from adjoining Tibet, but no biological surveys exist to confirm the status of the cats and their prey. Have snow leopards finally returned to the top of the world? Exploring this question was the main purpose of this research project. We systematically walked altogether 24 sign transects covering over 13 km in length in three valleys, i.e. Namche, Phortse and Gokyo, of the park, and counted several snow leopard signs. The results indicated that snow leopards have made a comeback in the park in response to decades of protective measures, the virtual cessation of hunting and the recovery of the Himalayan tahr which is snow leopard's prey. The average sign density (4.2 signs/km and 2.5 sign sites/km) was comparable to that reported from other parts of the cats' range in the Himalaya. On this basis, we estimated the cat density in the Everest region between 1 to 3 cats per 100 sq km, a figure that was supported by different sets of pugmarks and actual sightings of snow leopards in the 60 km2 sample survey area. In the study area, tahr population had a low reproductive rate (e.g. kids-to-females ratio, 0.1, in Namche). Since predators can influence the size and the structure of prey species populations through mortality and through non-lethal effects or predation risk, snow leopards could have been the cause of the population dynamics of tahr in Sagarmtha, but this study could not confirm this speculation for which further probing may be required.

Ishunin G.I. (1989). The Felids family Felidae Gray, 1821.
Abstract: Zoolites of the Felidae family are known from the Upper Eocene Lower Pliocene in Eurasia, Africa, and North America. Two sub-families are know to inhabit the territory of the USSR and adjacent territories: the extinct sabre-toothed Felidae species Machairodontia and now existing Felidae species. In the USSR the extinct Felidae species were found to exist in Upper Miocene, Upper and Middle Pliocene, and Pleistocene. In Eurasia panthers has been know since early Pliocene. Three species were found in Uzbekistan – the extinct cave lion Felidae sd†l…†… (Goldfuss, 1810), and now existing P…nth†a… tigris, P…nth†a… pardus. The ancient finds and modern habitats are briefly described. Genus Uncia is represented by one species snow leopard or irbis. Probably it appeared in later Pliocene or Pleistocene in the mountain of Central Asia. In Uzbekistan, remains of snow leopard were found in the Samarqand region in the layer of Upper Pleistocene or Holocene. Probably it moved into the area in Pleistocene or the period of glacier removal in the Western Tien Shan mountains, Turkestan, Zeravshan, and Hissar ridges.

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.

McCarthy, T., Khan, J., Ud-Din, J., & McCarthy, K. (2007). First study of snow leopards using GPS-satellite collars underway in Pakistan. Cat News, 46(Spring), 22–23.
Abstract: Snow leopards (Uncia uncia) are highly cryptic and occupy remote inaccessible habitat, making studying the cats difficult in the extreme. Yet sound knowledge of the cat's ecology, behavior and habitat needs is required to intelligently conserve them. This information is lacking for snow leopards, and until recently so was the means to fill that knowledge gap. Two long-term studies of snow leopards using VHF radio collars have been undertaken in Nepal (1980s) and Mongolia (1990s) but logistical and technological constraints made the findings of both studies equivocal. Technological advances in the interim, such as GPS collars which report data via satellite, make studies of snow leopards more promising, at least in theory.
