The complexity of (forested) river basins becomes particularly obvious in the context of their management and water quality. A sustainable management needs therefore an interdisciplinary approach. This approach should consider, to what extent the potential of forests in the water and matter cycle on the landscape scale can be used to meet the targests of the EC WFD. The management of forested river basins should focus more on the multifunctionality of forests. The long term maintenance of renewal and supply of water has to be seen much more as a serive of the forests, esp. with respect to the EC WFD. The option to affect the water quality and quantity by an adapted forest management are not unlimited. Basic conditions such as deposition, climate change, and economic conditions impact the service function of forests to a large extent. Despite the good knowledge of site related processes in forests there is from the point of view of the authors a considerable need to quantify the service of forests in middle to large scale river basins. In the context with the EC WFD we consider the following topics as crucial: - Better involvement of forestry in the management of river basins. - Definition of landscape specific forest partitions in river basins. - Improved effectivity of ecological-hydrological functions of forest by suitable geographical location in river basins. - Improved spatial estimation of atmospheric N deposition. - Better knowledge of sink/source functions of forest soils on the landscape scale.
