Forest-dominated catchment area in the Hochsolling region

The sub-area Sievershausen covers about 90 km2 and lies in the catchment area of the river Obere Ilme. In the northeast, the boundary of the sub-area corresponds to the borderline of the sampling area and the Nature Park.

Study areas of the Forest Ecosystem Research Centre (FZW) at the University of Göttingen and of the Northwest German Forest Research Institute (NW-FVA) are also located within the catchment area.

The sub-area is mainly used for forestry and agriculture and for gentle tourism.

Sampling site


  • A major primary producer in semi-natural and anthropogenic affected ecosystems.
  • As the most dominant deciduous tree species in Central Europe, it plays a significant role in most nearly natural and also anthropogenically influenced forest ecosystems up to an altitude of 1100 m.
  • As an organism living at ground level, it is a major driver of the decomposition of organic material (e.g. plant litter).
  • Soil is livelihood and biosphere for humans, animals, plants and soil organisms. All the substances brought in are transported, transformed and/or accumulated in the soil.
