  General Description   This biosphere reserve is situated in the estuary of the Taw and Torridge Rivers in North Devon.
A diversity of habitats is represented here. The core area comprises an active dune system with geomorphological and successional processes. Other habitats include a rocky foreshore, mud and sand flats, saltmarshes of various types, lowland farmland, grazing marsh, coastal heath, back-shore marsh as well as woodlands. As a result of the periodic review process in 2002, the Braunton Burrows Biosphere Reserve has been completely revised and extended by a consultation process among the local communities and the conservation and development authorities. It now encompasses a larger sector of the estuary of the Taw and Torridge Rivers.
About 53,000 people live in the biosphere reserve (2002) who are mainly engaged in services, manufacturing, agriculture and fishing. Braunton Burrows Biosphere Reserve is a site where traditional land use practices are still maintained today. Grazing by Soay sheep and cattle on saltmarshes was practiced for more than a century and still maintains the marshes in a condition suitable for wintering wildfowl. Traditional local fishery harvests Atlantic salmon sea trout and sea bass which are species that rely on the site as part of their lifecycle. Also mussel fishery and the harvest of ulva and laver are still practiced in a traditional way.
A special focus is given to young people at the Braunton Community College, located in the transition area, in order to make them familiar with the biosphere reserve concept.
