Biodiversity in peat grasslands of the Krimpenerwaard

In the Krimpenerwaard, the water level in the peat grasslands will be raised in the coming years and the banks of the ditches will be smoothened out. In Polder De Nesse and Berkenwoude this already started in 2017. We study habitat use of birds such as waders, ducks and herons in relation to these measures. We also investigate earthworms and insect densities and insects in wet and dry areas. In the first years, bird diversity appeared to increase and the grassland wetting did not have a negative impact on earthworms and insects. The project is commissioned by Provincie Zuid-Holland and is being carried out in collaboration with Zuid-Hollands Landschap, Courbois Flora & Fauna Expert and various volunteers.
