Site description A group of adjacent shallow lakes in the central part of north Pohjanmaa district. The lakes are nutrient-rich, partly resulting from nutrient input from melting snow and rivers. Equisetum and Phragmites dominate the vegetation, whilst the lakes are bordered by open mires, Betula and Pinus sylvestris fens, and mixed forests.

Key Biodiversity An important staging area for waterbirds, especially for Cygnus cygnus and also Tringa glareola (2,500 birds, spring) and Larus minutus (500-800 birds, spring).
