Site description
This site, located in the west and north-west of Portugal, includes a large estuarine area, salinas, freshwater marshes and alluvial forest associated with the River Vouga and its main tributaries, and shallower coastal waters offshore (to a depth of 20 m).

Key biodiversity
The site holds 20,000 or more wintering waterbirds on a regular basis, with important congregations of sea-duck offshore (Melanitta nigra) and waders on the intertidal flats (notably Calidris alpina). The freshwater marshes and estuarine areas support important breeding numbers of several waterbirds.
