Site description A very shallow (up to 3 m deep) nutrient-rich lake, with adjoining sedge-beds, transitional mires, alder Alnus woodland and willow Salix scrub. The lake shores are covered by beds of bulrush Scirpus, reed Phragmites and reed-mace Typha. Three-quarters of the lake bottom is covered by stonewort Chara and pondweed Potamogeton. The lake and a surrounding 100-m-wide belt are protected, but the area beyond is cultivated.
