The Wadden

The Wadden Sea is the largest unbroken system of intertidal sand and mud flats in the world. It’s one of the last remaining large-scale, intertidal ecosystems where natural processes continue to function largely undisturbed. It’s an annual breeding and wintering ground for 12 to 15 million birds and home to numerous plant and animal species.

The site covers the Dutch Wadden Sea Conservation Area, the German Wadden Sea National Park and most of the Danish Wadden maritime conservation area, all in a stretch of about 500 kilometers long and on average 20 kilometers wide.

The 43 inhabited and uninhabited Wadden islands together occupy more than 1000 square kilome­ters and are home to around 80,000 people. The biggest islands are the Dutch Texel, the German Sylt and the Danish Rømø.
