The area includes long sections of the Schelde and Durme rivers, with very rare freshwater tidal river marshes as well as mudflats, marshes, reedbeds, oxbows and wet meadows.
This is an important site for wintering and migrating waterfowl. The area is also nationally important for migrating Botaurus stellaris, Ixobrychus minutus and Porzana porzana, and breeding Alcedo atthis.
