Site description (2000 baseline)
Kvismaren is a flat fertile agricultural valley. Extensive marshy areas originally surrounded two lakes, but following drainage in the 1880s the lakes disappeared. They have now been replaced by extensive reedbeds (Phragmites) and Salix thickets surrounded by marshy meadows, low-lying pasture and arable land, and densely wooded areas. The main wetland is enclosed by embankments and canals to protect nearby arable land from flooding. Three areas of open water, covering c.230 ha, have recently been restored as shallow lakes or water-meadows. The IBA contains an important ornithological station.

Key biodiversity
The site is important for breeding species of wetland and wet grassland habitats, as well as for passage wildfowl and waders. Breeding species of global conservation concern that do not meet IBA criteria: Crex crex.
