Site description Kilsviken is a nutrient-rich bay off Lake Vänern and is surrounded by agricultural land. The shoreline is largely made up of reedbeds (Phragmites) and water-meadows and there is rich aquatic vegetation. Associated with Kilsviken is Kolstrandsviken Bay, which is moderately-rich in nutrients and contains mudflats, and åråsviken Bay. The northern part of åråsviken supports extensive areas of Phragmites, and grazing-meadows and damp forests occur on the many islands.

Key Biodiversity The IBA is important for breeding waterbirds and raptors, and as a stop-over site for migrating waders. Wintering species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (4-8 birds).
