Site description (2000 baseline)
Siikalahti Bay, one of the most famous wetlands in Finland, is a sheltered, shallow bay of Simpele lake. It is heavily vegetated with Phragmites, Typha and floating plants like Nymphaea, with open water constituting no more than 25% of the lake area. Eutrophication is mostly due to the input of large amounts of nutrient run-off from adjacent farmlands and sewage disposal from nearby settlements. Sammallampi lake, connected to Siikalahti Bay via the Simpele lake water system, is a small eutrophic lake surrounded by farmlands and forests. The vegetation is similar to Siikalahti, but overgrowth does not pose a significant threat in the near future.
Very important for wetland breeding birds. Species of global conservation concern that do not meet IBA criteria: Anser erythropus (max. 1, passage), Crex crex (1 pair, breeding).
