The Belarus part - Belovezskaja Puszcza Fot. The forest lacks fully primeval patches, like these found Polish part, but in the whole it is much better preserved. Tere is group of ponds and the forest is bordered by large wetlands, inhabited by birds usually associated with Biebrza. PTOP produced a nature map with the bird spots there, but access for foreign visitors is very difficult and expensive.
