The Green Belt was designated part of Germany’s National Natural Heritage in 2005 and highlighted as a beacon project in the German government’s National Strategy on Biological Diversity.

After years of negotiations, 2010 saw the completion of a process in which federal land comprising part of the National Natural Heritage in the Green Belt was transferred free of charge to the various Länder and their nature conservation foundations.

This secures the land for nature conservation activities and is of great importance in conserving and fostering the Green Belt as part of the national ecological network.
