The forest, part of it contained within a national park, is also home to the largest colony of European bison, or wisent, as well as to species that are rare or even extinct elsewhere.

Filling the gap in the wisent's evolutionary history helped explain why two distinct types of bison — one with long, one with short horns — have been found in ancient cave paintings.
