Once, shellfish reefs - mainly flat oysters - covered about 20% of the North Sea floor, but diseases, pollution and overfishing have led to a significant decline. As part of the Haringvliet Dream Fund Project (, ARK
Nature and World Wildlife Fund Netherlands are working on shellfish reef restoration. Shellfish, such as mussels and flat oysters, are keystone species for marine biodiversity, since they filter the water, provide shelter and nursery grounds for many marine animals, serve as attachment substrate for plants and range of animals, including birds. They also play an important role in natural coastal protection. Therefore, mussel and flat oyster reef restoration is attempted within the Haringvliet coastal zone (the so-called Voordelta).
This project is co-funded by the ministry for Economic Affairs, the ministry for and Environment, province of South Holland, Port of Rotterdam, National Postcode Lottery and LIFE. ARK Nature leads this project. The North Sea Flat (a cooperation of Wageningen Marine Research, Bureau Waardenburg and Sas Consultancy) is responsible for the execution of the current two pilots: maintenance, monitoring, analysis of monitoring results and reporting.
