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.
