A large freshwater lake subject to fluctuations in water level. The site includes wet meadows, floodplains, bogs and mires. Vegetation consists of various emergent aquatic plants and "mari" complexes of low peatmoss bog forests. These include "yerniks", brushes of birches, willow, ledum and sedges, and sparse larch Larix gmelinii forests with Siberian dwarf-pine. The site is very important for large numbers of breeding, molting and migrating waterbirds. The wetland supports populations of rare species, in particular the largest populations of swan goose Anser cygnoides and Steller's sea eagle Haliaetus pelagicus in the Amur region. The site supports various regionally rare forest plants and provides feeding grounds for several fish species. The major human activity is commercial fishing.
