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: 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.

Abstract: It describes natural conditions, area, flora and fauna of the three mountain nature reserves in Uzbekistan: Chatkal, Kyzylsu, and Miraki. Siberian mountain ibex, roe deer, wild boar, Turkistan lynx, Tien Shan brown bear, fox, stone marten, Menzbier's marmot, porcupine, ermine, and Tien Shan souslik inhabit the Chatkal nature reserve. Snow leopard can be found in a top rocky part of the ridge. In the Kyzylsu nature reserve, there are 23 mammal species including, among the others, white-clawed bear, snow leopard, Iranian otter, Turkistan lynx, wild-boar, badger, porcupine, long-tailed marmot, hare-tolai, stone marten, Pamiri shrew, and ibex; in the Miraki nature reserve snow leopard, white-clawed bear, ibex, wolf, fox, porcupine, long-tailed marmot, hare-talai, forest dormouse, red pica, and a number of Red Data Book bird species are protected.

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.
