Esipov A.V. (2000). Current state of snow leopard and its main preys in Hissar nature reserve.
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.
