A highly fragmented forest in the Wis³a valley, between the Bzura and Wis³a (Vistula) rivers. Coniferous and mixed forests cover banks of sand-dunes along the river terrace, below which lies the marshy valley floor, with watercourses flowing to the Bzura river. Marshy areas are covered with reedbeds Phragmites, sedge-beds, meadows, and riverine forest and scrub. Marshy areas higher up the terrace are covered by broadleaved deciduous forest. Former agricultural land, now abandoned (including whole villages), is situated mainly in the centre of the marshy zone, and is reverting to forest, aided by active afforestion.
The site is very important for breeding Crex crex. A total of 133 species have been confirmed breeding. In recent years (1980-1996) 5-7 species stopped breeding compared with the 1950-1979 period. Over the last quarter-century there have been 13 breeding species of raptor and seven non-breeding visitors or winterers. Three raptors (Falco peregrinus, Milvus migrans and Circus cyaneus) stopped breeding in the 1970s, one (Circaetus gallicus) in the 1980s, and Aquila pomarina is decreasing. Non-raptors which have stopped breeding in recent years at the site include Tetrao tetrix, Burhinus oedicnemus, Coracias garrulus and Lanius minor.
