Samenvatting

The international Wadden Sea is an estuarine tidal area along the North Sea coasts of The Netherlands, Germany and Denmark. It is characteristic for regions with sandy coasts and a medium tidal range. Fifty barrier islands separate the Wadden Sea from the North Sea, and an offshore transition zone to the North Sea. The tidal flats of the Wadden Sea form the largest unbroken stretch of mudflats worldwide. The present form of the Wadden Sea is still mainly the result of natural forces, although since the Middle Ages man has changed the Wadden Sea landscape by building dykes and reclaiming land. The Wadden Sea is an important nursery area for fish, a foraging and resting habitat for seals, and a foraging habitat for migrating waders. The Wadden Sea, including large parts of the islands, is a fully nature protected area and designated as a natural World Heritage site in 2009 (Wolff, 2013). The research group Marine Wetlands Studies at Stenden University is focusing on the sustainable development of tourism in the area. Current research has the purpose to get insight in to the effects of the World Heritage Status, in particular the natural values of the area, on future tourism development.
