General National Id Germany-02 Site name Osterbek and Bille river Summary The measures implemented at two river within the city of Hamburg (Germany) included the restoration of rivers and ponds (N1), the revitalization of flowing waters (N5), natural bank stabilization (N10), and channels and rills (U5). They targeted the National Biodiversity Strategy of Germany as well as the achievement of a good ecological status as defined by the WFD. For the identification of locations for possible measures the general public was involved using online forms. The implementation was then carried out by a local chapter of the German nature conservation NGO NABU. This NWRM proves to be highly effective while easy and cheap to implement, it is therefore considered a success. Light or indepth?

Key lessons After the first flood events it is visible, that the water body structure at the Middle Bille has been significantly improved. Due to different flow speeds and variability of the basin structure a positive short to medium term impact on biodiversity can be assumed.
