The Site is a large, flat-mire landscape, with large moraine deposits which create a mosaic of dry and wet areas interspersed with ponds and lakes. It is an important breeding and staging area for numerous bird species, many of them threatened and regionally rare. The mosaic landscape is ideal habitat for the greenshank Tringa nebularis and the whimbrel Numenius phaeopus. The Site is important for flood control during periods of heavy precipitation and snowmelt and acts as a water reservoir during droughts. Forestry is among the main sources of income in the area, and the Site itself is used for low-impact hunting and fishing activities, with some sheep and cattle grazing. Kvisleflået would be part of a potential Transboundary Ramsar Site with Sweden, and first efforts to coordinate the area’s cross-border management have been made.
