Site description (2000 baseline):
Site location and context
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.
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).
Pressure/threats to key biodiversity
The only reported problem is that of scrub invasion in some areas.
National High
International HighIBA overlaps with National Park (7,850 ha). 7,450 ha of IBA covered by Ramsar Site (Store Mosse and Kävsjön, 7,580 ha). IBA overlaps with Special Protection Area.
