After the Grevelingen was closed off by a dam in 1971, some 3000 hectares of new land were created. Several sandbars became permanent areas of dry land, along with salt marshes and many of the mudflats around the edges of Lake Grevelingen. The Slikken van Flakkee and Slikken van Bommenede mudflats are examples of this. Nature is allowed free reign here. The shore area underwent many changes as the salt water gradually became fresh water.
The unique location and the many areas that are regularly flushed with salt water have created a home for many unusual plants. Certain are closed to the public because of the vulnerability of the plants that grow there and/or the birds that nest there.
