Haringvliet. 29/08/00; Zuid-Holland; 10,880 ha; 051°46’N 004°15’E. Natura 2000 (SPA, SAC). The Ramsar Site boundary has been aligned to the Natura 2000 site, resulting in an increase of 152 ha. Formerly (together with Hollands Diep and De Biesbosch) one of the estuaries of the Rhine/Maas system, it was separated from the sea in 1970 and is now a 27-kilometre stagnant freshwater lake bordered by reedbeds, seasonally flooded agricultural land, sandbanks and mudflats. The water level is artificially regulated and varies according to the supply from the Rhine. The Site regularly supports more than 20,000 wintering waterbirds and nationally endangered and vulnerable species such as avocet, Eurasian spoonbill, Kentish plover and Sandwich tern. It also plays an important role as spawning, nursery and feeding ground for many fish, and supports nationally endangered molluscs such as the dun sentinel and German hairy snail. The main human activities within the site are commercial fishing, farming and agriculture, shipping, reed cutting, water management and hydro-electric power generation, recreation and tourism, research and conservation. There is a visitors’ centre at Tiengemeten Island. Potential threats to the Site’s ecological character are industrialization, urbanization, bottom sediment pollution, wind turbines and eutrophication. Ramsar Site no. 1244. Most recent RIS information: 2013.
