The Site is one of the largest string mires in southern Norway. It contains areas of transition between open water, bogs, and dry areas with mountainous birch forest. The central part of the Site is dominated by a small watercourse and Kulingstjern, the largest lake. There are also distinct glacial landforms such as drumlins, eskers and kames, formed by movements of ice and melted water during glaciation. 103 bird species have been recorded; for many northern and alpine bird species this is their southernmost breeding site. The Site is also important for reindeer during their calving season. In addition, it is valuable for carbon storage and sequestration. Human activities include nature conservation, fishing, livestock grazing, recreation, and tourism. More than 100 archaeological sites relate to iron works from the Viking Age and Middle Ages.
