Stream valleys in the Arnsberger forest (LIFE project)
Stream valleys in the Arnsberger forest (LIFE project)
Key features of the case study
At first glance, the streams in the Arnsberger Wald look quite natural. However, they have been straightened in historical times and much of the floodplain is covered by non-natural spruce forest and natural alder and oak riparian forests are missing along many streams. The objective of the project is to re-connect meanders, to enhance instream habitat and natural channel dynamics e.g. by the placement of large wood, and to restore natural floodplains as well as hydrologic balance e.g. to restore moor forests.
