Abstract: 10 snow leopards have settled in western extremities of the Hissar ridge. Almost 25 years ago, disturbed by anthropogenic activity, this rarest fauna representative abandoned the area being threatened. In a habitat usual for this species have now been created the Kyzylsu and Miraki nature reserves and the species is now rendering the highlands inhabitable again. Wild boar, Turkestan lynx, long-tailed marmot, snow leopard and black vulture, a total of 200 animal and bird species, can be found now in this area.

Abstract: A vertebrate fauna inventory in the Hissar nature reserve showed that various natural zones here are certainly inhabited by 45 species: amphibians one species; reptiles 12; mammals 32. Reptiles such as Alai snake-eyed skink and Central Asian viper and mammal species such as wolf, fox, brown bear, weasel, grey hamster can be found in all natural zones here up to 4,000 m above sea level. Snow leopard, Turkestan lynx, and long-tailed marmot can be found in the juniperous forests and higher elevations.

Abstract: Additional data on Lepus tolai, Ochotona rutila, Citellus relictus, Marmota caudata, Sus scrofa, Capra sibirica in western part of the Hissar ridge, Uzbekistan, is given here based on materials of the years 1978-1983. Information about distribution of these species, their numbers, food, enemies, and other ecologic issues is provided. Capra sibirica is a principle species snow leopard preys on. In 1899 1983, the authors recorded more than 20 cases of snow leopards' killing ibex of different ages.

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.
