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.

Abstract: All natural zones are represented in the mountains of Central Asia: deserts, semi-deserts, steppes, meadows, forests and shrubs, sub-alpine zones, alpine zones. Irbis (snow leopard) is a typical inhabitant of highlands. In the USSR, snow leopard is distributed in the mountains of Central Asia and southern Siberia. Outside the country this species is met in the Himalayas, Tibet, mountains of Mongolia. It is rare everywhere. The annual world trade is less than 1,000 animals. Being a non-numerous species, it causes negligible damage to farming and hunting industry.

Abstract: It provides general information about the Besh Aral nature reserve (Kyrgyzstan), its physico-geographical characteristic, and description of flora and fauna. The predatory mammals are represented by 12 species. The rare predators are brown bear, snow leopard, lynx, and manul. Snow leopard inhabits the highlands of Chatkal depression and the upper-river Kara-Toko. In the past, snow leopards were seen more often.

Abstract: An identification table for genus and species of mammals of Russia and adjacent areas is given. The taxonomy, morphology, distribution and life history of carnivores are described. The features of genus Uncia and species Uncia uncia, geographical variability, distribution, biology and value are described in detail.
