For the first time in Ukraine, the population of the corsac fox Vulpes corsac Linnaeus, 1768 is described; it enumerates, depending on seasons, 20???25 individuals. This single recorded population oceurs close to boundaries of the ???Streltsovskaya Step??? Nature Reserve. The hight and thickness of snow cover is shown to be the limiting factor for the corsac population. The further prospectives of distribution of the corsac are rather uncertain, because of reduction of suitable areas; it needs immediate inclusion to the Red Book and providing of conservation arrangements.
