Biebrzanski National Park was established on September 9, 1993. This Park covers a large part of the Biebrza proglacial valley, protecting most of the valley's peatland. Its total area is 59,223 ha. The main task of the Park is to protect the variety of species of fauna and flora within the existing ecosystem, including various kinds of peats and peat-bogs. An elaborate ecosystem of the Biebrza River valley can exist only if proper water conditions are maintained. The Biebrza River Valley is the largest and the best preserved area of low bogs in the temperate biogeographical zone. The ecological characteristics of the Biebrza Marshes as well as their vastness, contributed to the survival of the fauna, typical of natural swamp and water ecosystems, which is nearly extinct elsewhere. The Biebrza Marshes provide a good living environment for elk, beaver, wolf, crane, black grouse and many other species. Here they can find peaceful feeding grounds. The most attractive site in the Park is the Red Marsh (strict reserve), one of the biggest marsh area in Europe.
