It was created on 19 June 2001 in the region of the lowest stretch of the Warta river, up to its confluence with the Odra (Oder), which marks the Polish–German border.

This was why the former Słońsk preserve, which now forms part of the park, was in 1984 covered by the Ramsar Convention, whose purpose is to protect such areas.

On the other hand, nature in swampy areas closer to the Warta, is mainly untouched and as such is an interesting object of studies for biologists from Poland and other European countries.

The main threat to the park's ecosystem is the return of bigger plants to the delicate systems of meadows and pastures.

The park's Board owns a small lodge with five overnight rooms for 15 persons and a guest-house for about 30 visitors.
