An extensive, open and barren lakeland area forming part of the very large inland waterway of Saimaa lake. The site mainly comprises open water with small scattered islands, although a few are larger and forested. These forests hold an unusually high proportion of deciduous (mainly Betula) trees, as a result of slash-and-burn agriculture which was common in the area until the beginning of this century. The lake is nutrient-poor (oligotrophic) and the shores support only a few beds of sparse reed Phragmites.
Also a nationally important breeding area for Gavia arctica (10-50 pairs) and Larus fuscus fuscus (10-50 pairs). The forests hold breeding populations of the nationally scarce Dendrocopos leucotos. Species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (1-5 individuals, passage).
Pressure/threats to key biodiversity
Boating and landing on small islands is common in summer, which causes disturbance, particularly to Gavia arctica, gulls and terns. Part of the area is a candidate SAC.
