Grevelingen. 29/08/00. Zuid-Holland, Zeeland. 13,753 ha; 51°45'N 004°00'E; Natura 2000 (SPA). The Site is an 18km-long intertidal area which was part of the former estuary of the Rhine and Meuse rivers until it was cut off from the North Sea in 1971. It is now a stagnant saline lake, mostly bordered by dykes, with some islets, sand dunes and wet meadows. The Ramsar Site boundary has been adjusted to the Natura 2000 site, and recreational areas, roads and agricultural land covering 78 ha have been excluded. The Site is particularly important for waterbirds: it supports large congregations with annual peaks averaging over 67,000 birds, while more than 1% of the biogeographical populations of 13 species of breeding and wintering birds are present. The main human uses are commercial fishing, water management, boating, tourism and leisure activities. The site is potentially threatened by encroaching industrialization and urbanization (with wind turbines creating specific threats), non-industrial pollution discharge and expanding recreational activities. Ramsar site no. 1272. Most recent RIS information: 2013.
