Topography.
The Bryansk Nature Reserve is part of the Nerusso-Desna woodland, a UNESCO-MAB Biosphere Reserve. This biosphere has been established on the bases of a well-developed network of protected areas, which are connected ecologically.

The Bryansk forests have diminished in size over time, and were once considered dense. 
Across the Ukrainian border is the Ukraine's Desnyansko-Starogutsky National Park, which has a forested section that has similar habitat similar to Bransksy's.
