Abstract: Snow leopard is an endangered species. Its number is steadily decreasing. In the USSR, snow leopard is distributed in the mountains of Central Asia: Pamir, Tien Shan, Djungar Ala-Tau, Tarbagatai, Saur. It is also met at altitudes ranging from 1,800 3,500 m above sea level. A total number of snow leopard in the USSR does not exceed 1,000 animals; according to other data 2,000 animals. A decreasing number of snow leopard and its habitat shrinkage is directly related to human's pursuing snow leopards (in the USSR snow leopard was for a long time being considered as a species causing damage to livestock so authorities gave premiums for catching/shooting snow leopards) and reduction of ungulate population. Snow leopards are now protected in mountain nature reserves of the USSR: Chatkal, Aksu-Djabagly, Ramit, Besh-Aral, Sary-Chelek, and Alma-Ata.

Abstract: A description of snow leopard number, distribution, reproductive biology, death reasons, and conservation measures in the USSR, where northern and north-western border of its habitat runs, is given. The population of snow leopard in the USSR is 500 1,000 animals. In the Inner Tien Shan, 400 snow leopards were caught 1936 through 1970. The maximum of 120 skins was purchased in Pamir in 1956 1958. Population of snow leopard directly correlates with population of ibex, a fact being verified by data collected on a long-term basis. Moreover, snow leopard was for a long time considered as a harmful animal, shooting of which was encouraged by premiums and resulted in reduction of snow leopard population.

Abstract: Irbis is distributed in highlands of Kazakhstan, Kyrgyzstan, Tajikistan, and Altai. It preys mainly on wild sheep and ibex, marmots, pica, snow-cock, rarer other ungulates, rodents and birds. Sometimes it attacks domestic sheep. At the beginning of spring this species is on heat, gestation period being 90 100 days. Female bears two three (to five) cubs. The litter splits in one year. The animal sheds hair twice a year. It has a low population and therefore hunting for snow leopard is prohibited.

Abstract: Any commercial use or sport hunting for snow leopard is prohibited everywhere. In the USSR, illegal hunting or attempt to hunt was prosecuted according to the criminal or administrative law. The following additional measures are required to successfully protect the species: conducting awareness activity in local communities, continuous control, quick investigating of snow leopard extermination cases, and regular counts of snow leopard population.

Abstract: Snow leopard Uncia uncia Scheber, 1775, has status I, that is rare, non-numerous and endangered species. Information about its distribution, habitats, biology, number, existing and required conservation measures in the RSFSR and USSR is provided. Total population in the USSR is 800 1,000 animals.
