Sand dune survey of Great Britain
Sand dunes are one of a series of terrestrial habitats that in Britain are almost entirely restricted to the coast. The others are saltmarshes, maritime cliffs and grasslands, vegetated shingle and strandlines. This dataset is made up of the results from vegetation surveys covering 49 sand dune systems in Wales. The specific objectives of the sand dune survey are: - To review existing knowledge of British dune vegetation; - To compile an inventory of the range and extent of dune vegetation throughout Britain; - To allow the national and regional importance of each individual site to be assessed; - To provide vegetation maps and descriptions for each site in sufficient detail to support site specific casework and conservation management, and to act as a baseline for future monitoring.

Vegetation surveys are based on the National Vegetation Classification (NVC) and survey techniques included the mapping of all vegetation types in each site. The area of each vegetation or other land cover polygon was calculated and results aggregated. Mapping covered 6,405 ha, of dune area excluding large extents of afforested sand. Adding afforested dune area, vegetated dune in Wales totalled 8101 ha and this probably represented almost all of the vegetated dune resources of Wales. Field survey also recorded geomorphological characterises of sites and the impact of human activities. This information was used to classify dune systems into types of dune, summarise erosion accretion data and describe human impacts.
