Abstract
The ecological status of water bodies in large protected areas (national park, biosphere reserve, natural park) has been markedly improved during the last decades. Active restoration measures, decrease of liquid and gaseous emissions and changes in land use led to an improvement and stabilization of waterquality. Acidification of metarhitral brook reaches in lower mountainous areas has decreased; canals and ditches in fens serve today also for maintenance of moor landscapes. Restored and re-connected oxbow lakes serve as optimal habitat for fauna and flora of the river and the floodplain. The very different water bodies of the large protected areas in the Harz Mountains, in the Elbe floodplain and in the Drömling fen represent today regional hotspots and refuges of aquatic biodiversity.
