Site description
A freshwater lake and the largest bog in Sweden south of Lapland. Kävsjön was formerly much larger but drainage in the 19th century reduced its size considerably. This led, however, to the creation of important damp grasslands on the reclaimed land and these areas are now being managed for birds, after a period of neglect. Store Mosse comprises fen and raised bog habitats with scattered sandy ridges (covered by Pinus) and sand/gravel/rock moraines. The only land-uses are grazing and conservation activities.

Key biodiversity
An important site for large spring passage numbers of Cygnus cygnus, Anser fabalis and Grus grus. Three species listed on Annex I of the EC Birds Directive also breed: Porzana porzana, Grus grus and Asio flammeus. Species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (non-breeding).
