The Saiga (Saiga tatarica) is a critically endangered antelope which originally inhabited a vast area of the Eurasian steppe zone from the foothills of the Carpathian Mountains and Caucasus into Dzungaria and Mongolia. They also lived in North America during the Pleistocene. Today, the nominate subspecies (S. t. tatarica) is only found in one location in Russia (steppes of the northwest Precaspian region) and three areas in Kazakhstan (the Ural, Ustiurt and Betpak-dala populations). A proportion of the Ustiurt population migrates south to Uzbekistan and occasionally Turkmenistan in winter. It is extinct in China and southwestern Mongolia. The Mongolian subspecies (S. t. mongolica) is found only in western Mongolia.
