Abstract: Presented is history of the Chatkal nature reserve's establishment, physic and geographic description, types of soils, climate, altitude zones, flora and fauna, historical monuments. Snow leopard is quiet rare species in nature reserve. Last years irbis's tracks and voice have been recorded in highly mountain sites of Maidantal part of Chatkal nature reserve.

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.

Abstract: Represented is fauna of big salt-marsh valleys and pre-Kyzylkum area, a tier of low desert foothill valleys, tiers of lowland ridges, deeply cut hillside midlands, and cold highlands of the watershed ridge-top tier in the Jizak region of Uzbekistan. The highest tier of the Jizak region, a habitat of snow leopard, Menzbier's marmot, Siberian ibex, sometimes wild Tajik sheep coming from the East, bear ascending from lower elevations, and wolf in summer, has the most adverse living conditions. Central Asia argali and stone marten inhabit in central part of the North Nurata ridge.

Abstract: Snow leopard inhabits in zones of alpine meadows and juniper forests. Main preys are ibexes and wild sheep. Irbis included in Red Data book of USSR.

Abstract: Snow leopards are to be found in the most extreme eastern, southeastern and southern mountainous regions, including the Altai. Saur, Tarbagatai. Dzhungarian, Alatau, Northern and Western Tian-Shan ranges. The snow leopard or irbis is the most rare in eastern Kazakstan in the ranges of Katunskie Belki, South Altai, Kurchumski, Sarymsakty, Saur and Tarbagatai. Total snow leopard population in Kazakstan is estimated at no more than 100-110 animals, including 20-25 in the central part of the Zailisky-Alatau. Although there are nine protected areas in Kazakstan, snow leopards are only regularly reported
from the Aksu-Dzhabagly and Almaty reserves and occasionally in Markakolsky Reserve. The major threats to the species include: Deliberate poaching with the aim of selling the valuable fur of the snow leopard; habitat loss resulting from the expansion of human activity in its mountain habitat, and deliberate or retaliatory killing by shepherds in response to predation upon livestock.
