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: 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.

Abstract: It describes distribution and number of ibex in four parts of the Hissar nature reserve in Uzbekistan. The total number of ibex is estimated to be 1,500 animals. The natural enemies of ibex are snow leopard, wolf, and lynx. Data about ibex's food, seasonal migrations, and threats are given. Decreasing forage reserve and poaching are considered as the most serious threats. A buffer zone is suggested to be established in the areas adjacent to Tajikistan and the Surkhandarya region of Uzbekistan.

Abstract: In Uzbekistan, snow leopard (Uncia uncia Schreber, 1776) is met in the mountain ridges of Tien Shan (Karjantau, Ugam, Pskem, Chatkal, and possibly Kurama ridges) and Alay (Turkistan, Zaravshan, Gissar, and Baisuntau ridges). There are about 50 snow leopards there. They are observed to decrease in number for the reasons as follows: extensive use of alpine pastures, tourist activity and poaching. Irbis is under protection in the Chatkal, Zaamin, and Gissar nature reserves and Zaamin people's park. An additional measure to be taken to protect this species is to expand the area of the Chatkal nature reserve, to better fight against poaching activity and advocate snow leopard protection in mass media.

Abstract: It described history of the Chatkal nature, flora and fauna, scientific and conservation activities. Snow leopard, brown bear, Menzbier's marmot, golden eagle, snake-eagle and lammergeyer inhabited in nature reserve. These species included in Red data book.
