. Because of this unique succession, the area supports vast numbers of wildlife with many birds and mammals common.

The water marshes in the area are commonly flooded and the resulting alluvial soil supports an array of waterside vegetation.

It is one of the largest wildlife refuges in Europe. Biebrza flood waters is a real kingdom of birds - seen here over 250 species, more than 80% of Polish avifauna. Starting in the early spring mating birds attract birdwatchers from around the world.

, breeding area for many bird species associated with the marsh environment. Biebrza Valley is an ornithological particular importance, especially as the wetlands are disappearing in the landscape of Europe, and the birds of these groups lose their basis of their existence. There are also isolated position boreal breeding species, and species whose geographical center is located in the taiga and tundra zone. In addition, Biebrza Valley is of great importance for many species of birds feeding and resting during the annual migrations. Bird siewkowatych, requiring vast wetlands, Biebrza is one of the most important sites in Central Europe.
