They were placed under protection in 1995 and consist of three physically separate areas of land: the Misselhorn Heath (Misselhorner Heide), the Schillohsberg Heath (Heide am Schillohsberg) and the Weesener Weg Heathland (Heideflächen am Weesener Weg).
The region referred to as Heathland and Rough Pasture in the Südheide (Heiden und Magerrasen in der Südheide) with an area of 278.3 hectares (688 acres) was also declared as Special Area of Conservation No.
Only occasionally, in the wetter locations, is the cross-leaved heath (Erica tetralix) also found.
bladderworts (Utricularia), an endangered genus of carnivorous plants that occur in fresh water and wet soil, are found in several, smaller, boggy or wet locations, as is the spoonleaf sundew (Drosera intermedia), another protected carnivorous plant.
Other plants found here include the protected common lousewort (Pedicularis sylvatica), which is on the red list of endangered vascular plants in Germany, and the rare marsh gentian (Gentiana pneumonanthe).
