Site description (2000 baseline)
The site encompasses the nutrient-rich lake and adjoining wet forest and open areas with many swamps. Most of the previously pastured areas are no longer used, and have reverted to swamps occupied by young alder Alnus wood or sedge meadows. Open water is not extensive, and the greater part of the lake is covered by reedbeds Phragmites. There are seven islands (all forested). The Oœwinka river (tributary of the £yna) rises from the lake.

Key biodiversity
Breeding species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (one pair), Crex crex (four pairs). A total of 126 species have been recorded.
