The Markermeer was created in 1976 by the construction of the dike between Enkhuizen and Lelystad, whereby the water was cut off from the sea and rivers. The Markermeer once had a rich plant and animal life, with many algae and aquatic plants. This situation changed due to the disappearance of the natural dynamics of the area. The situation will be restored by the construction of islands with sand, clay and silt from the bottom of the Markermeer. The ambition is to turn the Marker Wadden into a large island group of 10,000 hectares. This makes it one of the largest nature restoration projects in Western Europe.
Nature in the Markermeer is given an enormous boost by creating favorable living conditions for aquatic plants, shellfish, birds and fish. There will be islands with natural banks and spawning grounds. This creates a robust new nature reserve with clear water in the heart of the Netherlands. A pearl where life is good for migratory birds, fish, other animal species, and certainly also for people.
