Abstract: The work contains data on biology snow leopard in Hissar nature reserve, Uzbekistan. The number of snow leopards in this reserve has increased from two or four in 1981 to between 13 and 17 individuals in 1994. Since 1981, snow leopards have been sighted 72 times and their tracks or pugmarks 223 times. In the Hissar Nature Reserve snow leopards largely feed on ibex. Over a period of 14 years, 92 kills and remains of ibex aged from one to thirteen years of age have been examined. Other records of predation, by the number of events observed, include 33 cases of juvenile and mature horses, 25 long-tailed marmot (Marmota caudata). 18 Himalayan snowcock (Tetraogallus himalayemis), 17 domestic goat, 13 wild boar (Sus scrofa), five domestic sheep and three incidents involving cattle. Twenty-two attacks on domestic flocks were reported, and these occurred during both the daytime and at night. Snow leopards usually mate between the 20th of February and March 20th. The offspring are born in late April to May, and there are usually two per litter (23 encounters), although a single litter of three has also been recorded.

Abstract: Presented is history of the Hissar nature reserve's establishment, physic and geographic description, types of soils, flora and fauna The 28 species of mammals, 103 nested birds, 19 amphibians and reptiles and 2 fishes are presented in nature reserve. Number of snow leopard assessed as 2-3 families, bear 130 individuals, wild boar 460, Turkestan lynx 90,ibex 1700 individuals.

Abstract: As a result of paleontologic and ecologic research on the south of Uzbekistan 35 rare and endangered mammal species were detected: rare species: bear, steppe polecat, otter, chaus, lynx, manul, sand cat, leopard, snow leopard, Bukhara deer, Goitered gazelle, ibex, markhor, Asian argali, and others; extinct species: dhole, striped hyena, cave hyena, tiger, elephant, horse, kulan, Pleistocene donkey, rhinoceros, Knobloch's camel, roe deer, moral, argali, aurochs, and bison.

Abstract: In Uzbekistan, this species is distributed in spurs of Tien Shan and Gissar. It preys on ibex, rarer on argalis, roe-deers, young wild boars. In winter, it attacks livestock and sometimes feeds upon marmots and smaller rodents. Snow leopard attacks man very rarely, only when wounded. The economic significance of this species is low, since only few skins are traded. Its dressed skins are used as rugs.

Abstract: Snow leopard and its habitat within the USSR and Uzbek SSR are described. Its habitat in the Chatkal and Hissar ridges are described too. Given are data concerning alimentary biology, reproduction, and attitude to man. Female snow leopards become mature at the age of two three years, male at the age of four years. Reproduction occurs once every two years. Presumably, there are 10 animals in the country. Snow leopard is protected in four nature reserves in Uzbekistan and a number of nature reserves in neighbour countries.
