"The Wadden Sea comprises the Dutch Wadden Sea Conservation Area and the German Wadden Sea National Parks of Lower Saxony and Schleswig-Holstein. It is a large temperate, relatively flat coastal wetland environment, formed by the intricate interactions between physical and biological factors that have given rise to a multitude of transitional habitats with tidal channels, sandy shoals, sea-grass meadows, mussel beds, sandbars, mudflats, salt marshes, estuaries, beaches and dunes. The inscribed site represents over 66% of the whole Wadden Sea and is home to numerous plant and animal species, including marine mammals such as the harbour seal, grey seal and harbour porpoise. It is also a breeding and wintering area for up to 12 millions birds per annum and it supports more than 10 percent of 29 species. The site is one of the last remaining natural, large-scale, intertidal ecosystems where natural processes continue to function largely undisturbed..
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."
