Abstract: In Russia, traditions of track observations and the use of tracking techniques in studying the ecology and behavior of mammals were founded by A.N. Formozov. An analytic review of his data on large carnivorous mammals (tiger, snow leopard, wolf, brown bear, wolverine, and others) is given. A special detailed observation of animals' tracks as a source of information on their life is shown only to start. The efficiency of track observations in various fields of studies, including counting animals, is estimated. The values of day and night distances for various animal species, given in literature, have never been properly substantiated methodically. The tracking method is the most effective in studying the use of the home range by animals, drawing the network of their movements and scent-marking behavior. The hunting behavior of large predators in dense forests is can only be deduced by observing their tracks. In some cases, the use of tracking has a distinct advantage over radio tracking. The main propositions are illustrated by the materials of the author obtained in various Russian regions (in forests of the northern Russian Plain and southern Far east) for 1958-1998.

Abstract: Over the last decades tiger, leopard and snow leopard were fully exterminated in many areas, where they formerly were common species and now became very rare ones. Few leopards can still be found in Caucasus, Copet-Dag (Turkmenistan) and south of Primorskiy krai. Irbis is remaining a common species only in the difficult-of-access highland areas of Tien Shan and very rare in the Altai. Tiger traces are sometimes found in the Amudarya river valley and in the taiga Sihote-Alinya in the Far East.

Abstract: The Zailiyskiy state natural national park is suggested to establish in the center of northern micro slope of Zailiyskiy Alatau. There are 42 mammal, 138 bird, tow amphibian, and eight reptile and fish species, and 145 daylight butterfly species in the Zailiyskiy Alatay. Of them, seven mammal species such as argali, Tien Shan bear, snow leopard, Turkistan lynx, stone marten, Central Asian otter, and Indian porcupine are included in the Red Data Books of Kazakhstan and USSR.

Abstract: Data about faunistic complexes of Bostandyk region is provided. Snow leopard inhabited in high mountains of Chatkal, Pskem and Ugam ridges. The tracks of irbis were recorded in the snowfield near the edge of Pskem ridge (upper Ichnach-say river).
