Extensive nature reserve in deep forest.

The forest was drained for many years by a dense ditch system. In order to win back the area for the site-typical alternating damp to wet forest communities and the rare animal and plant species that depend on them, the old ditches were closed and new dams were built. The result is a rewetted area in which toads and dragonflies feel very much at home. The beaver has also found ideal conditions here and is happily building dams and cave systems. He fells even the biggest trees. The area is worth visiting at any time of the year.
