Abstract: Reasons for ibex and argali mortality from natural enemies, parasites, infections, accidents, and hunters are analyzed. Snow leopard is one of the most dangerous enemies of ibex and argali, preying equally on both young and mature animals (mostly males). Snow leopard feeds upon ibex all year round. Unlike wolf, snow leopard would never kill several animals at a time, but only one selected victim. The food remains left by these predators are different in terms of the skull gnawing. Nasal bones and eye-sockets on the skull of ibex killed by snow leopard remain undamaged, while wolf gnaws off nasal part of the skull, breaks eye-sockets, eats lower jaw, widens occipital hole and pulls out brains. Snow leopard leaves large pieces of skin around the skeleton of the victim, whereas wolf tears it to shreds or eats up fully. Sometimes parts of the victim left by snow leopard are eaten by wolf. It is easy to mix the remains of snow leopard's or griffon vulture's food. The remains differ in skin being turned inside out rather than torn to large pieces.

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: An expert evaluation of the numbers of snow leopard and its preys, Siberian ibex and long-tailed marmot, was made on the basis of surveys conducted in Hissar nature reserve in 1999. The total number of the snow leopard is estimated at 12-16 individuals, whereas that of the Siberian ibex at 1000 individuals. An average density of the population of the long tailed marmot ranges at 4,8 individuals per ha. The ratio of the numbers between the snow leopard, Siberian ibex and long tailed marmot is 1:68:450. The major threats for the snow leopard are poaching on the borders of the nature reserve, a decrease in of preys, shrinking of the range in areas adjoining the nature reserve as a result of intensification of industrial activities and disturbing factors. For the Siberian ibex and long tailed marmot the major limiting factors are the shrinking of the areas and deterioration of the forage value of the high-mountain pastures, as well as the direct competition for forage with domestic animals at the sites adjoining the territory of the nature, as well as disturbing factors.
