Features

The Dyfi is one of the best examples in north-west Europe of a salt marsh estuary, which has been relatively unaffected by industrial development. A wide range of estuarine habitats are present, including rare peatland-forming areas.

Cors Fochno is of international importance due to its estuarine raised mire and is one of the largest active raised mires in the United Kingdom. The geomorphology, flora and invertebrate faunas are significant and fragile.

The site supports the only regular wintering flock of Greenland white-fronted geese in England and Wales, and is a key site in Wales for breeding waders. There is a significant tourist economy based on the area’s geographic, historic and cultural background and the river provides recreational, and educational benefits with the estuary and its surrounding landscape being a predominantly agricultural area supporting Welsh-speaking farming families and communities.
