Project summary

Edit project overview to modify the project summary.

Restoration measures in the middle part of the river Regge are part of plans to restore the whole river. In 2006, the streambed was made made more narrow and given a meandering trajectory. Some abondoned meanders were reconnected to the stream. The bed was elevated further. Mowing in the main channel was suspended, while the floodplains were maintained by grazers.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

These measures created a varied landscape with low natural levees. Some isolated meanders got a more grassy vegetation than intended because of a high nutrient load.
