Waterdunen
Waterdunen in Zeeuws-Vlaanderen is an innovative conservation project that integrates coastal defence, nature, and recreation across an area of approximately 350 hectares. Located near Breskens, the site features a unique tidal culvert built into the dike, allowing filtered seawater to flow controlled into the hinterland, creating a saline tidal ecosystem. This dynamic environment provides handy conditions for wading birds and specialized coastal flora that have become rare elsewhere in the Netherlands. Artificially constructed islands offer secure nesting sites for terns and avocets, while a network of hiking trails leads visitors through the salt marshes and mudflats. Officially completed in 2021, the project also functions as a buffer against rising sea levels by absorbing tidal surges. Waterdunen exemplifies how modern engineering can be utilized to create ecologically valuable landscapes that coexist with human infrastructure and coastal safety requirements.
