Braunton Burrows is the largest sand dune system in the UK. It hosts an extraordinarily diverse plant community, with over 400 recorded species of vascular plants. This in turn means that there are also a great variety of associated invertebrate species. Its uniqueness and biodiversity is recognised in its designation as both a National Nature Reserve and as a UNESCO biosphere reserve. Braunton Burrows is located in the South West of England, in North Devon, to the west of the town of Barnstaple.
