The Dee Estuary SPA
The Dee Estuary is on the boundary between England and Wales on the north-west coast of Britain. It is a large, funnel-shaped, sheltered estuary that is made up of sand-flats, mud-flats and saltmarsh. The site is of major importance for waterbirds. During the winter, the flats and saltmarshes provide feeding and roosting sites for ducks and waders. In summer, the site supports breeding populations of two species of terns at levels of European importance. The site is also important during migration periods, particularly for wader populations moving along the west coast of Britain.
MPA TypeSpecial Protection Area
Special Protection Areas (SPAs) are strictly protected sites designated uner European legislation. They are established to protect rare and vulnerable birds and for regularly occurring migratory species.
