The Influence of the Brown Bear (Ursusarctos) Population Increase on the Populations of Wild Ungulates in the Republic of Buryatia and the Amur Region

The purpose of this work is to determine the effect of brown bear population growth on the population of wild ungulates by the example of Amur Region and the Republic of Buryatia. Studies were conducted in spring, summer, autumn and winter by routing bear trails and natural habitat areas and collecting animal activity observations. The sizes of individual species’ habitats were determined as well as predator’s influence on wild ungulates, living on the same territories, was studied. During research studies, conducted over a period of 10 years, a direct relation between bear population growth and wild ungulates’ population decrease on the territories under consideration was established, and, in case of active predator population control, an inverse relationship was revealed as well.
