The Wadden Sea

The Wadden Sea is one of the largest and most important tidal wetland biotops in the world. Its incredible biodiversity and environmental and geomorphological importance was decisive for its inclusion in the UNESCO world heritage list.

The site is also one of the last remaining natural, large-scale, inter-tidal ecosystems where natural processes continue to function largely undisturbed.

The Wadden Sea is also Europe’s largest connected area of mud and sand flats and in total it represents 60 percent of all the tidal areas in Europe and north Africa. In addition to the mudflats, there are also many other environments, like salt meadows, dunes, sandbanks, which are all part of the established protected area.

Also very special and unique is its incredible biodiversity. More than 12.000 different species live in the Wadden Sea, including marine mammals like common seals, gray seals, harbour seals and porpoises and fish like European plaice and the common sole. In the Mudflat there are also numerous mussels, crabs and worms. The huge food availability makes the Wadden Sea so interesting for migratory birds, who use it as a resting area. On average around 10 million birds migrate through the the Wadden Sea every year.

In 2011 the world heritage committee decided to include in the world heritage list the Waddensea of Hamburg and in 2014 also the Danish part of the Waddensea. Now the whole world heritage area covers around 11.500 km².
