The steppe birch mouse is a rare and non-abundant species of small mammals of the fauna of the Crimean Peninsula existing here in two isolated populations—western (Tarkhankut) and eastern (Kerch)—separated from each other by 200 kilometres of anthropogenic landscapes. The results of large scale long-term epidemiological censuses showed that the ratio of trapped steppe birch mice in the whole of the Crimea was 0.21 %, whereas the ratio of birch mice among small mammals in the steppe zone is 0.29 % with the relative abundance of 0.03 specimens per 100 trap-nights. The preservation the steppe birch mouse populations in the territory of the Crimean Peninsula requires a detailed study of its biology and ecology, especially limiting factors, as a basis to develop appropriate conservation measures aimed to protect of this species listen in the Red Book of Ukraine.
