The measure is a compensatory measure for the new construction of the Leibis/Lichte drinking water dam. South of Untersuhl, in the area of the Green Belt, a stream flowing into the Werra, including tributaries and floodplain, is being renaturalised. This will close the gap between existing renaturalisation measures and the confluence with the Werra. The processing area is located within several protected areas (nature reserve, FFH and bird sanctuary) and must therefore be harmonised with the protection and conservation goals.
