The largest of all Poland’s national parks, the Biebrzański National Park protects Europe’s major natural expanse of moorland peat bogs which are extend across the Biebrza River valley. The peat bogs occupy an area of 59,223 hectares.
The greatest attraction of the park is the splendid, open, high moor topography and the uncommonly rich wildlife and plant cover.
The Biebrza River marshes are known worldwide as the nesting site of many rare species of European aquatic birds and birds of prey (approx. 235 species, including 157 nesting birds).
In spring, when the Biebrza overflows its several square kilometer flood plain, thousands of migratory birds gather here and can be watched from viewing platforms.
The Biebrza River Valley is also Poland’s largest wildlife refuge for elk, wolf, beaver, and otter. The Biebrzański National Park attracts many enthusiasts of a bloodless form of hunting, most of them armed with cameras and microphones.
The park is under the protection of the RAMSAR International Convention.
