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.

Abstract: Presented is history of the Chatkal nature reserve's establishment, physic and geographic description, types of soils, climate, altitude zones, flora and fauna, historical monuments. Snow leopard is quiet rare species in nature reserve. Last years irbis's tracks and voice have been recorded in highly mountain sites of Maidantal part of Chatkal nature reserve.

Abstract: It provides a zoogeographical description of Central Asia mountains: Tien Shan (west and east), Pamir, the Turkestan and Hissar ridges, and ruinous mountains in Kyzylkum. Distribution of various animal species over the area under study is described. Data concerning Central Asia sheep, ibex, and snow leopard in the alpine meadow zone, and data concerning the otter (in the Tupalang river basin) and grey partridge is presented. The author noted that generally fauna of Tien Shan, Hissar, and Pamir is similar to that of Inner Asia. The other type of fauna more similar to that of Transcaucasia is typical for Kopet-Dag.

Vyrypaev V.A. (1974). The influence of sarcoptosis on the population of Capra sibirica Pall. in Western Tien Shan (Vol. Vol. II.).
Abstract: Given is data concerning disease (sarcoptosis) of Siberian ibex (Capra sibirica) in Western Tien Shan. The carriers of the disease are adult males of Capra sibirica during distant migrations that as a rule take place in anticipation of snowy winters or owing to human influence. Ibexes are not merely infected with sarcoptosis but perish enmasse from the disease. In the first year the disease strikes down, in the main, migrants – adult males. Predators including snow leopard kill the weakened animals. During the recent five years the density of Carpa sibirica at the Chatkal Mountain-Forest Reservation dropped 2.3-fold as a result of sarcoptosis and owing to the migrations caused by the reduction of the population. Is recommended: 1. Stringent veterinary control at places of possible contacts between infected domestic animals and healthy wild ungulates. 2. Using modern technology migration routes of ungulates should be studied for elaborating effective measures of quarantine.

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.

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.
