Site description (2000 baseline)
Freshwater lakes with wooded islands and peninsulas. Lake shores have parkland, reedbeds, deciduous forests, meadows, fields and scattered habitations. Artificial landscapes are mainly arable and improved grazing-meadows, and may include some more natural humid grasslands but the extent is unknown. The deciduous forest includes extensive areas of Alnus carr, areas of mature Fagus and Quercus forest, and some conifer plantations.

Key biodiversity
The most important freshwater area in Denmark for birds and the only Danish freshwater area designated as a Ramsar Site. A very important breeding site for Botaurus stellaris. More than 20,000 waterbirds regularly occur on passage. Species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (1 pair breeding). Circus aeruginosus and Sterna hirundo, both listed on Annex I of the EC Birds Directive, also breed at the site.
