Abstract: Of 27 vertebrate animal species inhabiting the mountains of southeastern Kazakhstan and included in the Red Data Book of the USSR (1978) and Red Data Book of Kazakhstan (1978), 11 are mammals (free-toiled bat, Menzbier's marmot, dhole, Tien Shan brown bear, stone marten, otter, Turkistan lynx, snow leopard, manul, and argali). Snow leopard is met in the nature reserves Aksu Jabagly and Almaty. In the Almaty nature reserve snow leopard migrates outside the protected area following the ungulates. The extension of the nature reserve would improve the protection.
