Guide to more biodiversity in stream valleys

Natural processes and habitats for endangered species

Like the coasts of Denmark, nature in the stream valleys is often home to large, cohesive natural areas with great potential for restoring more self-managing nature. The interplay between the stream and the wet nature in the stream valley is important for this restoration. However, many streams have been straightened out and made deeper – with major negative consequences for the surrounding natural areas. The large herbivores of the past have disappeared, and in many places the farmer’s grazers have also disappeared from the stream valley. For this reason, overgrowth has become a major problem for biodiversity. Nature and the areas in the stream valley have many functions, e.g. climate adaptation, uptake of nitrogen, drainage and grazing areas.

This website is a guide to nature restoration in stream valleys, with biodiversity as its main goal. The guide deals with the process of a restoration project, from initial considerations, prioritization of initiatives, mapping of conservation status, land use history and hydrology, restoration and follow-up management (see figure below).

Subpages have so far only been prepared in Danish. If you would like to know more, please contact us.
