Erosion is weakening the dikes. Wageningen UR scientists investigated whether more varied vegetation on dikes can hold the ground together more effectively. They discovered that quadrupling the number of plant species on the dikes cuts erosion levels in half.
In this system, species take each other’s place when one of them disappears. A mixture of flowers, herbs and grasses can only be successful, however, if the clippings are removed consistently. In this way, adaptive green management can make the 17 thousand kilometres of dikes in our country safer and more beautiful. This is one of the ways Wageningen UR is working on improving the quality of life.
