Wadden Sea

The Wadden Sea, designated a UNESCO World Heritage site, stands as the world's largest unbroken tidal flat system, extending across the Netherlands, Germany, and Denmark. This vital ecosystem supports over 12 million migratory birds annually, including 30% of the global black-tailed godwit population. The area also serves as a crucial spawning ground, contributing significantly to the region's seafood production and underscoring its immense ecological and economic importance.
