This is a spatial dataset containing a collation of all mapped sand dune habitats in Wales. Over 40 NVC Phase 2 surveys were carried out on sand dunes across Wales. This dataset is a collation of data from these surveys grouped together for mobilisation purposes and to provide information on a Wales-wide scale. One of the major strategic initiatives of the former Countryside Council for Wales (CCW). The purpose of this data capture was to help define the sand dune vegetation resource of Wales. The surveys were initiated in the late 1980's and continued until the mid '90's. Digitisation of the maps took place in 2004.
