The solar-powered irrigation system is ready for use. At two selected flood channels, it can maintain areas with moist soils and open mudflats as feeding habitats—particularly for meadow birds—well into late spring. This is a bridging measure until more fundamental improvements to the landscape’s water management in the Rhine floodplain take effect.

In August, a comprehensive survey of fish stocks was conducted in the restored floodplain waters. “The initial results are promising,” says Klaus Markgraf-Maué, project manager and board member of the NABU-Naturschutzstation Niederrhein. “We observed high fish densities, indicating that the measures are effective. Now, it’s important to continue monitoring and optimizing the development of these habitats.” This success assessment is being carried out by experts from Limnoplan, who record, count, and measure the fish by species. “The data gathered provides valuable insights into the role of these waters in the fish life cycle and will help us tailor future measures even more effectively,” adds Markgraf-Maué.

 

Around the oxbow lake restored last summer at the center of the nature reserve, a lush stand of flowering rush has developed, extending into the water with clusters of water dropwort and fringed water lily. The open, muddy shore sections in between are now used by migratory wading birds such as snipe, greenshank, and green sandpiper.

Open water surfaces and shallow wetlands, such as the new Schaar flood channel, once again shape the early spring aspect of the floodplain in the project area. Here, moist soils and low-growing floodplain grasses will enrich the floodplain habitat well into summer.

The water levels in the floodplain are pleasingly high at the moment. Rare wetland habitats can thus recover from the droughts of recent summers and are hopefully better equipped to withstand future dry periods. Nature conservation measures that we are implementing as part of this LIFE project are helping to keep this valuable water in the wet meadows for longer and thus preserve rare animal and plant species. However, the construction site for the current measures has been paused for the time being due to the flooding.
