Other Site Characteristics

A former estuary, 18 km in length, which was closed from the sea in 1971. It is now a stagnant saline lake, mostly bordered by dykes with islets, sand-dunes and wet meadows. It adjoins SPA Voordelta (NL9802017) to the west, and SPA Krammer-Volkerak (NL1000021) and SPA Oosterschelde (NL3009016) to the east.

4.2 Quality and importance

The site holds one of the four most important populations of the vole Microtus oeconomus arenicola of the SW. Netherlands metapopulation. The site regularly supports more than 20,000 wintering waterbirds (1991/92-1995-96)Very important breeding colony of Sterna sandvicensis; important for passage and wintering waterfowl. New IBA 021-00 (van denTempel & Osieck, 1994).
