Central coordinates 29o 10.00' East  62o 41.00' North
IBA criteria A4i, B1i, B3, C2, C3, C6
Area 1,150 ha
Altitude 90 m
Year of IBA assessment 2000


Site description A complex of shallow, nutrient-rich wetlands south of the town of Outokumpu, surrounded mainly by farmland, but also by young deciduous forests which regularly flood. Areas of formerly quite extensive open, muddy marshes are now overgrown by sedge, grasses and Salix bushes. In shallow water, large beds of reed Phragmites are abundant.

Key Biodiversity Nationally important for breeding Botaurus stellaris (7-9 males), Circus aeruginosus (5-6 pairs). In 1984, the first evidence of breeding Tringa stagnatilis in western Europe was found in the area; it has since bred twice.
