1. Ukok PlateauKosh Agach Ukok Plateau is a remote and pristine grasslands area located in the heart of southwestern Siberia, the Altai Mountains region of Russia near the borders with China, Kazakhstan and Mongolia. The plateau is recognized as part of the UNESCO World Heritage Site entitled Golden Mountains of Altai as an important environmental treasure. It provides a habitat for many of the world's endangered species including one of its least studied predatory animals: the snow leopard. Other endangered species protected there include the argali mountain sheep, the steppe eagle, and the black stork. There are several threats to the preservation of the Ukok Plateau, including overuse of the steppe by ranchers, a proposed road, and plans for a gas pipeline between China and Russia.
