Pechgraben bei Klein-Krotzenburg Nature Reserve in the Hessen Protected Landscape Network
A preserved mosaic of ancient floodplain terrain and wetland habitats.
Located in the Offenbach district, this nature reserve protects a rare post-glacial flood channel of the Main river. The site exhibits a diverse landform mosaic, ranging from near-natural broadleaf forests to expansive sedge marshes. It functions as a critical protected geography for regional species, maintaining its ecological character against the surrounding agricultural and residential development of the Lower Main valley.
