Marker Wadden - English version

Natuurmonumenten (Dutch Society for Nature Conservation) is going to restore one of the largest freshwater lakes in western Europe by constructing islands, marshes and mud flats from the sediments that have accumulated in the lake in recent decades. These 'Marker Wadden' will form a unique ecosystem that will boost biodiversity in the Netherlands.

Marker Wadden archipelago, unprecedented

On Tuesday the 26th of January 2016 Michiel Rijsberman, the Vice King’s Commissioner of the Dutch Province of Flevoland, invited European stakeholders to learn more about one of Europe’s largest nature restoration projects: ‘Marker Wadden’. Read more >

Lake Markermeer (700 km2) used to be part of the Dutch Zuiderzee, but is now cut off from the North Sea and rivers by dams, dikes and reclaimed land. The lake has barely any natural shores, and its waters are often extremely turbid as wind and waves churn up the accumulated sediments from the relatively shallow lake floor (2-4 m deep). As a result, fish and bird populations have declined dramatically. 

About Natuurmonumenten

Natuurmonumenten is one of the largest private organisations for nature conservation in the Netherlands. We manage over 100,000 hectares (1,000 km2) of land and water, from large nature reserves to small natural areas of high ecological value and beauty. Natuurmonumenten is run by and for people who care for nature. 

Natuurmonumenten wants to reach out to people of all ages and backgrounds. We want to share our love and fascination for nature. Because nature is a source of inspiration and wonder. And because nature is under pressure, particularly in our densely populated country. Therefore we protect nature areas, valuable landscapes and cultural heritage. All over the Netherlands, and for all people. We preserve nature for future generations by purchasing land, managing nature reserves and making natural areas accessible for all. Our work is made possible by volunteers, members, benefactors and corporate sponsors.
