This is an extension of the Dutch and German Wadden Sea site, inscribed on the World Heritage List in 2009. The Wadden Sea is the largest unbroken system of intertidal sand and mud flats in the world. The complete extension now covers most of the Danish Wadden Sea maritime conservation area, as well as a maritime extension of the Dutch Wadden Sea Conservation Area and the German Wadden Sea National Parks of Lower Saxony and Schleswig-Holstein."
