McCarthy, K., Fuller, T., Ming, M., McCarthy, T., Waits, L., & Jumabaev, K. (2008). Assessing Estimators of Snow Leopard Abundance (Vol. 72).
Abstract: The secretive nature of snow leopards (Uncia uncia) makes them difficult to monitor, yet conservation efforts require accurate and precise methods to estimate abundance. We assessed accuracy of Snow Leopard Information Management System (SLIMS) sign surveys by comparing them with 4 methods for estimating snow leopard abundance: predator:prey biomass ratios, capture-recapture density estimation, photo-capture rate, and individual identification through genetic analysis. We recorded snow leopard sign during standardized surveys in the SaryChat Zapovednik, the Jangart hunting reserve, and the Tomur Strictly Protected Area, in the Tien Shan Mountains of Kyrgyzstan and China. During June-December 2005, adjusted sign averaged 46.3 (SaryChat), 94.6 (Jangart), and 150.8 (Tomur) occurrences/km. We used
counts of ibex (Capra ibex) and argali (Ovis ammon) to estimate available prey biomass and subsequent potential snow leopard densities of 8.7 (SaryChat), 1.0 (Jangart), and 1.1 (Tomur) snow leopards/100 km2. Photo capture-recapture density estimates were 0.15 (n = 1 identified individual/1 photo), 0.87 (n = 4/13), and 0.74 (n = 5/6) individuals/100 km2 in SaryChat, Jangart, and Tomur, respectively. Photo-capture rates
(photos/100 trap-nights) were 0.09 (SaryChat), 0.93 (Jangart), and 2.37 (Tomur). Genetic analysis of snow leopard fecal samples provided minimum population sizes of 3 (SaryChat), 5 (Jangart), and 9 (Tomur) snow leopards. These results suggest SLIMS sign surveys may be affected by observer bias and environmental variance. However, when such bias and variation are accounted for, sign surveys indicate relative abundances similar to photo rates and genetic individual identification results. Density or abundance estimates based on capture-recapture or ungulate biomass did not agree with other indices of abundance. Confidence in estimated densities, or even detection of significant changes in abundance of snow leopard, will require more effort and better documentation.

Abdunazarov B.B. (2002). Biodiversity of mammals in the Western Tien Shan and its conservation.
Abstract: The mammal fauna of Uzbekistan's mountain ecosystems is represented by some 60 species. Data on mammal species composition in the Western Tien Shan (48 species) and Pamir-Alai (57 species) is given. A quantity of species endemic to the mountainous ecosystems of Uzbekistan is defined. Quantities of nine rare species inhabiting the mountain ecosystems, including snow leopard, are given. Number of snow leopard in Pamir-Alai and the Western Tien Shan is estimated to be 30-50 animals.

Mitropolskiy O.V. (2004). Biodiversity of mammals in Uzbekistan: results of the studies; conservation, use and monitoring projects (Vol. N 8.).
Abstract: The article reviews conservation projects regarding valuable species of the West Tien Shan such as snow leopard, Tien Shan brown bear, Tien Shan and Karatau argali, Menzbier's marmot. The questioning revealed three cases of poaching snow leopard in the West Tien Shan in Kazakhstan, and 11 in Uzbekistan. A necessity to severely suppress any acts of poaching or skin trade is emphasized. A number of measures is suggested to preserve the species.

Abstract: Reports on a 3 yr winter study of snow leopard movements and activity, based on following tracks in the snow in Tien Shan Mountains of USSR. Travel route preference is examined with regard to snow and terrain characteristics, and prey abundance. Snow leopard kills of ibex and hare are noted

Abstract: The counts of species populations such as Menzbier's marmot, roe-deer, ibex, wild boar, wolf, Tien Shan brown bear, and snow leopard has been made on permanent transects in the Chatkal reserve for 18 years. Data on of the population numbers is provided. 11 encounters with snow leopard were registered during a period of 1975 through 1979. Two encounters were recorded in 2000.

Abstract: It provides a brief description of game fauna in the West Tien Shan including the Ugam, Pskem, Chatkal, and Kurama ridges, characterized by high diversity and practical value of predatory mammal species (including snow leopard), Artiodactyls, rodents and birds. There arises a question of game fauna enrichment and game management regulating on this territory.

Koshkarev E.P. (1990). Geographic prerequisites for snow leopard conservation in the USSR.
Abstract: Three key areas of the snow leopard habitat in the USSR are geographically segregated: Central Asia (Pamir, Tien Shan, Pamiro-Alai), East Kazakhstan (Jungar Alatau, Tarbagatai, Saur), and South Siberia (Altai, the Sayans), which are separated from one another. The fate of snow leopard in East Kazakhstan and South Siberia causes the most anxiety.
