The nature park was established in 2004 and has been recognised as an Important Bird Area (IBA) by BirdLife International because it supports populations of whooper swan (Cygnus cygnus), taiga bean goose (Anser fabalis), corncrake (Crex crex) during their migration and nesting. Birds, mainly waterfowl (geese, swans, ducks, gulls), congregate here during spring migration to rest in flooded fields and meadows. During the autumn migration, the concentration of birds in the territory of the nature park was not observed. The most important nesting bird species in the park are northern lapwing, corn crake, common quail, lesser spotted eagle, Montagu's harrier, etc.
