Marais poitevin et baie de l'Aiguillon


Year of compilation: 2000

Site description
A complex of many habitat-types. Human activities include stock and arable farming, oyster and mussel farming, and grazing on reclaimed saltmarshes.



Key biodiversity
The site holds 20,000 or more waterbirds, on passage and in winter on a regular basis. Species of global conservation concern that do not meet IBA criteria: Crex crex (5-6 breeding pairs); Tetrax tetrax (20-50 passage individuals); Acrocephalus paludicola (passage).



Pressure/threats to key biodiversity
The site is seriously threatened by drainage of the wet meadow areas. Intensive agricultural practices, channelization of rivers and streams, removal of hedges, scrub and tree-lined channels, drainage of saltmarshes and salinas, and extension of oyster and mussel farming on the mudflats also pose significant problems. In addition, communal meadows of the Vendeé marshes are affected by the creation of lakes for wind-surfing. Approximately 10,000 ha of the IBA is proposed as a Special Protection Area (13,000 ha).
