Studies of birds in grasslands
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.
The combination of rewetting measures improves bird community
Since 2016, the water level was raised in combination with flattening ditch banks. Would that work for the typical bird species of the peat grass landscape? In an evaluation of bird numbers, distribution and measures, we were able to demonstrate statistically significant improvements on a spatial scale for species such as black-tailed godwit, redshank and lapwing. The combination of measures is positive, including wetttened fields, higher water levels and the ditch banks. Great knowledge for follow-up projects.

Lowland Ecology Network
The Lowland Ecology Network is a network of freelancers who focus on ecological research, advice and communication. The emphasis is on nature protection of wetlands at home and abroad. Each participant has specific expertise and as a network we can respond fast and quickly solve complex issues. We are wel connected with experts on subjects such as photography / film, design and nature legislation.
