Voordelta. 29/08/00; Zeeland, Zuid-Holland; 92,271 ha; 051°43’N 003°35’E; Natura 2000 (SPA, SAC). The Ramsar Site boundary has been aligned with the Natura 2000 site, resulting in an increase of 3,502 ha in its area. The Site is an extensive coastal wetland in the North Sea, characterized by shallow sandbanks, mudflats, salt meadows and embryonic dunes. Its high food productivity, caused by the increased nutrient supply from the rivers Rhine and Meuse, attracts an outstanding range of species that depend on it. Threatened birds such as the Sandwich tern, Eurasian spoonbill and avocet use the Site during migration and winter, as do more than 1% of the population of northern pintail and sanderling. The shallow mudflats are a very important spawning and nursery ground for migratory fish such as river lamprey and allis shad. Moreover, common seal and grey seal regularly use the Site. The main human uses include intensive aquaculture and shellfish fishing, angling, boating, recreation and tourism. All these uses put pressure on its ecological character, as do other potential threats such as the disturbance of birds by aircraft, non-industrial pollution, construction work on dykes and dams, extraction activities and reclamation projects. The management plan for the Natura 2000 site has been approved. Ramsar Site no. 1279. Most recent RIS information: 2013.
