Abstract: Being one of nine nature reserves in Uzbekistan, Chatkal was established in 1947. Its area changed its size and administrative jurisdiction. Foothills adjacent to the nature reserve were long ago inhabited and developed by people. In Middle Ages, the area of juniperous forest reduced considerably because of mining operations. There are rare mammal species in the nature reserve, such as snow leopard, bear, Menzbier's marmot, and six rare bird species

Abstract: The reference book on taxonomy of modern mammals in the USSR provides classification from order to species, list of synonyms for all taxons, and indicates types and typical habitats, and places of storage of typical exhibits. Fauna of the USSR has one species of genus Uncia Grey, 1854 Uncia uncia (Schreber, 1776).

Abstract: Snow Leopard Felis (Leopardus) uncia S c h r † b., 1778 is distributed in the mountains of Central Asia, Turkmenistan (very rare) and Turkestan, on Tarbagatay, Altay, Sayans and in Uriankhay area. Subspecies haven't been described. Body length is about 130 cm, tail length 90 cm.

Abstract: The monograph provides taxonomic description of sub-genus Panthera Oken, 1816, genus Uncia grey, 1854. Snow leopard inhabits the mountains of Tajikistan, the Pamirs, Tien Shan, Tarbagatai, the Altai, the Sayans; also the mountain of Mongolia, Tibet, the Himalayas, and Hindukush, where it keeps to alpine meadows and woodless rocks at up to 3,000 – 4,000 m above sea level in summer, and descends to a lower elevation in winter. It described from the Altai. They are of minor trade importance. This species is rare all over its habitat and included in the Red Data Book of the USSR.

Abstract: There are two isolated snow leopard populations in Uzbekistan, both of which are located along the fringe of the species' distribution. These groups are the Pamir-Alai and the Tien-Shan, of which are united to snow leopard range in neighboring Tadjikistan and Kyrgyzstan. Apart from animals inhabiting the Hissar Nature Reserve, the Pamir-Alai population consists of animals inhabiting the upper portion of the Tupalang River basin and the mountains around Baisuntau. This population is currently estimated at about 30 individuals, from which as many as 10 individuals are reported to be killed or captured annually. However, we suspect the loss rate is more like five to eight individuals, with the entire Pamir-Alai group in Uzbekistan numbering 22 – 25 animals. The Tien-Shan snow leopard sub-population group of Uzbekistan occupies the high-mountain portions of practically all of the large ridges in the area, including Chatkal, Pskem, Ugam and Talass Alatau. The number of snow leopards harvested from this sub-population appears to be five or seven individuals, with the total number placed at 27-32 individuals. The major factors restricting snow leopard numbers in Uzbekistan appears to be poaching of both snow leopard and its large prey species like ibex, as well as disturbance associated with the intensive development of the alpine lands for pasturing livestock. In order to preserve the snow leopard in Uzbekistan it will be necessary to control and eliminate poaching. Additional habitat could be provided by expanding the Chatkal Nature Reserve by adding lands in the Shavassai River basin as well as Akbulak River basin.
