Abstract: The Red Book includes data of rare and endangered fauna and flora species. The species are sub-divided into five categories by threat. Volume 1 of the Red Book of the Uzbek SSR includes 22 mammal species, 31 bird species, five reptile and five fish species. Among them there are endemic species and species included in the International Red list. Snow leopard is referred to a category of endangered species.

Abstract: The network of Tajikistan's protected areas (four nature reserves, 14 national and 18 regional sanctuaries, one national park) is described. The establishment of `Shakhristan state complex nature reserve' and `Sarykamish state complex reserve', and interstate nature complex park on northern slope of the Turkestan ridge is recommended to improve conservation practices for a number of endangered vertebrate animal species in Northern Tajikistan (such as brown bear, snow leopard, wild sheep, and others).

Abstract: This survey was being done (May, 1975 February, 1976) in the new Kyzylsu nature reserve, established in 1975. Before 1975, the anthropogenic pressure was mainly represented by overgrazing and unregulated hunting. Provided are data on bird species (bearded vulture, Himalayan vulture, griffon vulture, golden eagle, and Himalayan snow cock), mammal species (long-tailed marmot, Indian porcupine, brown bear, lynx, snow leopard, and Siberian ibex).

Abstract: 50 mammal species permanently live in the nature reserve. There penetrate snow leopard, wolf, corsac, and wild boar on a relatively regular basis. Moral, roe deer, and elk migrate outside the Markakol depression in winter. Though mentioned in literature as species inhabiting the nature reserve, beaver, stone marten, and dhole are not met there today.

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.
