There is a place where heaven and earth share the same stage

Welcome to the Wadden Sea World Heritage site

The Wadden Sea is the largest tidal flats system in the world, where natural processes proceed undisturbed. It extends along the coasts of Denmark, Germany and the Netherlands.

The Dutch-German Wadden Sea became World Heritage in 2009, followed by the Danish part in 2014. The Wadden Sea was inscribed into the UNESCO World Heritage List for its globally unique geological and ecological values. Nowhere else in the world is there such a dynamic landscape with a multitude of habitats, shaped by wind and tides. Biodiversity on a worldwide scale is reliant on the Wadden Sea.

Denmark, Germany and the Netherlands have been joining forces for its conservation for over 30 years, taking responsibility of preserving this irreplaceable ecosystem for the benefit of present and future generations.

Protecting and managing the site

The Wadden Sea is a natural area of global importance shared by three countries. At the same time, the Wadden Sea is surrounded by a significant population. Therefore, the continued priority for the protection and conservation of the Wadden Sea is an important feature of the planning and regulation of use, including within land/water- use plans.

Fact

140 species

Many of the species of fish recorded in the Wadden Sea are visiting species from the North Sea. Others use the Wadden Sea as a passage during their migration from the sea to the rivers, as an important nursery area for juveniles, or as a spawning area in the North Sea. These fish stay as adults in the Wadden Sea as adults. About 20 species are resident in the Wadden Sea and leave the tidal area only during exceptionally cold winters.
