WMS of spatial masks for calcareous, coastal, upland and lowland heath landscapes in England

This web map service displays existing and potential areas of habitats associated with calcareous, coastal, upland and lowland heath landscapes. The dataset was initially created to provide a sampling framework for a field survey carried out in 1992 and 1993 by the Institute of Terrestrial Ecology (later part of the Centre for Ecology & Hydrology). It was derived from a range of geology, soils, altitude and land cover data.
