“Kjellerhaugvatnet Nature Reserve lies in an open landscape between Nes and Svea (see map) and was established in 1997. The reserve covers an area of 1 995 decares, of which 1 610 decares are land. The region includes a number of lakes and tarns surrounded by swamp and bog, between low inclines and heather moors. The aim of the protection is to preserve an important wetland area with its naturally occurring vegetation and animal life.
It is especially important to protect the migratory and breeding region for the wetland birds and the botanically rich bog areas there.
A wealth of mountain vegetation
In the north is a secluded area of tidal pools and shallows with a number of small islands and islets. Particularly in the western part, the notable presence of chalk has given rise to a very lush growth of rock plants and the occurrence of bogs with rich vegetation. The lakes are shallow and fertile, especially Kjellerhaugvatnet and Sveavatnet.
In the middle of the reserve is the small abandoned farm called Gråven. An unmarked path between Nes and Svea goes directly past the remains of the farm which was inhabited by a family between 1906 and 1921.
Important nesting sites
The area is particularly valuable as a breeding ground for a large number of wetland birds. Many rare species of birds nest in the reserve. This and the Holandsosen Nature Reserve complement each other in providing for the needs of the migratory and wintering birds such as the Whooper swan, the grey goose, ducks and wading birds.
Several rare or less common species of birds may be observed in the migrating seasons, such as great egret, mute swan, snow goose, gadwall, little grebe, hen harrier, common moorhen, common waterhen, common crane, pomarine skua and snowy owl”.
