File:Coastal erosion threatens the North Frisian Islands.jpg

English: This image, acquired by one of the Copernicus Sentinel-2 satellites on 8 March 2022, shows the North Frisian Islands, an archipelago located between Germany and Denmark, in the North Sea. Between the Sylt Island and the mainland, lies the Wadden Sea. This area, together with the mudflats that are exposed during low tides, is part of the Schleswig-Holstein Wadden Sea National Park. The area is home to a unique biodiversity and is for this reason it has been made into a protected nature reserve part of the Natura2000 network. The mudflats are particularly important for bird migration, as they attract around 12 million specimen each year and constitutes the primary winter habitat of 34 different bird species. The North Frisian Islands, and especially the Sylt Island, are threatened by an erosion process that is rapidly damaging their environment and threatening their biodiversity. The Copernicus Marine Environment Monitoring Service (CMEMS) and the Copernicus Land Monitoring Service (CLMS) work closely together on a comprehensive coastal monitoring service able to address the complex dynamics of coastal erosion.
