The project follows a two-step approach to halting and reversing the impending threat of floodplain habitats as well as achieving fundamental and sustainable improvements to the local water budget.
- Improvement of the water budget and the hydrological connection between river and floodplain:
- Closure of drainage ditches
- Reinforcement of the water retention channel after flooding events and opening of the polder for summer floods
- Active irrigation using solar-powered water pumps to maintain soil moisture and increase frequency, extent and duration of water-logged areas in spring and early summer
- Construction of a new low lying water body to reduce fish kill in the shallow water bodies at decreasing water levels
- Reactivation of alluvial waters, tidal pools, temporary waters and optimization of habitats and habitat types
- Desludging of an oxbow lake
- Restoration of tidal pools and temporary waters
- Seed transfer to restore species richness of stream-accompanying semi-dry grasslands
