Shared between Mongolia and the Russian Federation, this site is an outstanding example of the Daurian Steppe eco-region, which extends from eastern Mongolia into Russian Siberia and northeastern China. Cyclical climate changes, with distinct dry and wet periods lead to a wide diversity of species and ecosystems of global significance. The different types of steppe ecosystems represented, such as grassland and forest, as well as lakes and wetlands serve as habitats for rare species of fauna, such as the White-naped crane, Great Bustard, Relict Gull and Swan goose, as well as millions of vulnerable, endangered or threatened migratory birds. It is also a critical site on the transboundary migration path for the Mongolian gazelle.
