A geographical information system (GIS) for Dorset heaths

Records in the form of maps of the distribution and extent of heathland in Dorset dating back to last century have been brought together in a GIS, using a modern base map. The rate and extent of fragmentation are clearly evident from the map series; the severe reduction in viability of the characteristic ecological communities in the scattered remnant areas points to the need for restoration as well as protection. The results of ecological survey over the last 25 years are being incorporated into a GIS to help identify which of those areas recently lost to heathland are likely to respond best to restoration, and give the best chance of success in terms of extending heathland viability
