Floodplains must contain a variety of fish habitats, among other things, to restore river fish biodiversity. This is the result of a large-scale study conducted by Wageningen University & Research (WUR) in collaboration with Rijkswaterstaat, which is published in Science of the Total Environment (STOTEN). Additionally, the extent to which the restored floodplain is connected to the river determines its success as a nursery.
