Biodiversity in the southern Eggegebirge


Bogs are complex ecosystems which consist of several habitats. According to the kind of water supply it is distinguished between raised bog (water supply by rainwater alone) and low bog (water supply by groundwater) and a variety of transition and mixed forms.

In this project we regard mainly two FFH-habitats which characterize the project areas significantly.

The habitat type 7120 consists of raised bogs which hydrologic balance is affected strongly for example by intensive peat mining. Supported by nature conservation means these bog areas have a high potential for regeneration by reinstating peat growth within a time frame of around 30 years.It is important for the new life in old bogs that species typical for raised bogs represent the major part of the complete vegetation and that no intensive cultivation of the bog areas have taken place.

Habitat type 7140 consists of moors and quaking bogs on peat substrate which are fed by near-surface or accrued, nutrient-poor water. Usually there is a bog core with typical raised bog vegetation and a surrounding area with bodies of water, mounds and siltation zones with sedges (bottle-sedge – carex rostrata).
