Roe deer
Its former distribution can be approximated by examining the distribution of ungulates in the region. Wild boar was the numerically dominant ungulate in forested habitats, along watercourses, in reed beds and in thickets of the Caspian and Aral Seas. Where watercourses penetrated deep into desert areas, suitable wild pig and tiger habitat was often linear, only a few kilometers wide at most. Red and roe deer occurred in forests around the Black Sea to the western side and around the southern side of the Caspian Sea in a narrow belt of forest cover. Roe deer occurred in forested areas south of Lake Balkash. Bactrian deer lived in the narrow belt of forest habitat on the southern border of the Aral Sea, and southward along the Syr-Darya and Amu Darya rivers.
