Flood protection dams impair the riverside ecosystems because they constitute barriers and require regular maintenance works that entail interferences in the ecosystem. On the other hand, they are important compensatory habitats for endangered organisms, for example types of extensive grassland, and therefore need to be cultivated carefully. In recent years, innovative means of promoting riverside ecosystems were established and successfully applied in the context of the maintenance works along the Danube. Nevertheless, preserving the functionality of the dams remains the top priority. The task for the coming years is the further development of the previously used methods and the promotion of their specific implementation along the Danube.
