The Site covers part of a lake within a representative agricultural landscape, of which the western part along with the adjacent land areas is protected as a nature reserve. The Site has rich and varied swamp vegetation, and very rich water vegetation with almost 40 registered water plants. The vegetation belt and swamp areas are excellent breeding sites for a number of nationally endangered birds, such as the garganey (Anas querquedula), the greater scaup (Aythya marila), and the nationally vulnerable smew (Mergellus albellus). More than 1% of the population of pink-footed goose (Anser brachyrhynchus) rests regularly at Fiskumvannet in spring and autumn. The main hydrological values of the Site are sediment trapping and shoreline stabilization. Some pike fishing is still practiced, especially during spring. Within the reserve, the land has mainly been used for grazing and mowing. The Site is used for birdwatching and other nature-based tourism, environmental education and transport.
