The fauna of the Central Ecological Zone of the Baikal Natural Territory is considered, which is unique because of the region’s peculiar geographical location responsible for an exceptionally large diversity of its species composition that includes many genetically and ecologically inhomogeneous elements. About 460 species of vertebrate animals occur on the study territory, many of which represent rare and endemic species. It is found that long-term economic development of the region’s ecosystems led to serious structural rearrangements of the animal world, the introduction of alien species, and a reduction and even disap pearance of separate animal species or populations. The map of the anthropogenic factors of disturbances to faunistic complexes of the Central Ecological Zone of the Baikal Natural Territory was compiled, illustrating the main types of impact on the com munities of vertebrate animals and the magnitude of their manifestation.
