The term Sager Schweiz comes from large sandy and shifting dunes, which used to threaten to cover farmsteads, meadows and fields. By measures in the 18th century, such as the construction of a porch, one ultimately tried successfully to stop the dune migration. Today, the up to 5m high dunes are overgrown. As a result, the vegetation could grow undisturbed, although there were regular cuts of the trees, as well as bite of animals, so that today you can find a stock of wonderful old crater oaks and other strange shaped trees here on the sand hills.
Wikipedia: "Kratt is the North German name for a coppice with small and sometimes engulfed overgrown trees.
A Kratt is caused by unfavorable conditions on barren soil and strong wind-exposed areas and by the special form of management: the trees have been "cut" for the production of firewood again and again and could only grow by ruff. Such stocks reach heights of up to 3 m. Only a few tree species tolerate this use and are represented in the Kratts, u. a. Pedunculate oak, Aspenwood, Juniper, Buckthorn and Birch. Kratts with a high proportion of pedunculate oak are also called Eichenkratt. In Eichenkratts the bark was also used for the production of Gerberlohe.
Kratts have a high value for nature conservation because of their own, rare and endangered plant and animal life. Since they decreased in number and scope due to the ongoing cultivation, some have been protected early. "
The highlight marks the eastern foothills of this natural monument - from here, following the road further to the west, you will be able to discover the hilly landscape well.
