The Restoration of degraded wetlands in Wolfschlugen (in the administrative district of Stuttgart) was conducted within the wider regional level of sustainable urban development to enhance resilience, protect the city from flooding, support sustainable development, and safeguard biodiversity. Ditches and craters line the 700 metres long and 50 - 70 metres wide strip of landscape northeast of the development boundary behind the Wolfschlugen forest cemetery. This is formed by the Riederwiesen, which absorb water to protect the place from flooding. The wetland should protect people at least during a so-called hundred-year flood and at the same time offer animals and plants a habitat. (ref 3, 11)

Overview
Nature-based solution
- Blue infrastructure
- Rivers/streams/canals/estuaries
- In-land wetlands, peatlands, swamps, and moors
- Green areas for water management
- Rain gardens
- Swales and filter strips
- Sustainable urban drainage systems
Key challenges
- Climate action for adaptation, resilience and mitigation (SDG 13)
- Climate change adaptation
- Green space, habitats and biodiversity (SDG 15)
- Green space creation and/or management
- Water management (SDG 6)
- Flood protection
- Stormwater and rainfall management and storage
- Improvements to water quality
Focus
Creation of semi-natural blue areas, Management and improved protection of rivers and other blue areas, Ecological restoration of degraded ecosystems, Protection of natural ecosystems
Project objectives
1. Decrease the level of drought;
2. Decrease the duration and volume of water deficit;
3. Increase a natural habitat diversity;
4. Improve water quality;
5. Creation of a natural buffer against flooding;
6. Creation of new recreational area for Stuttgart citizens (ref 1, 11).
Implementation activities
The following implementation activities were realized,
1. Valorization of wetlands
2. Modeling of wetlands
3. Trenches and craters along approximately 700 meters long and 50 to 70 meters wide landscape strip were introduced in Wolfschlugen to mitigate the rise of water during possible flooding. The biotope thus serves as a protection against flooding
4. New plants planted in the area to create a place for the retreat of local citizens
5. In order to observe the animals and the plants better, a small wooden bridge through the densely covered terrain was established (ref 1, 11).
Climate-focused activities

Project implemented in response to ...
... an EU policy or strategy?
Unknown
(LIFE (“The Financial Instrument for the Environment”) is a program launched by the European Commission and coordinated
by the Environment Directorate-General (LIFE Unit - E.4) (4). The program produced a document "LIFE and Europe’s wetlands
Restoring a vital ecosystem" which contains planning recommendations (4) but no direct reference was made to this in the project documents. )
... a national policy or strategy?
Yes
(1. In the 1970s Germany signed off on an International Wetlands Convention, agreeing, among other things, to protect its marshlands.
2. The Ramsar Convention is an international agreement for the protection of wetlands of international importance, especially as a habitat for water and water birds. Germany joined the Ramsar Agreement in 1976 and has so far designated 35 Ramsar areas. In Baden-Württemberg region (to which Stuttgart belongs to), the three Ramsar areas of Wollmatingerried (767 hectares) and Mindelsee (459 hectares) and the cross-border Ramsar region of Oberrhein / Rhin are designated as areas of international natural importance (ref 7, 10). )
