As the economic value of these uses declined, considerable areas of heath were lost to agriculture, forestry, housing, roads, mineral working and other uses, and today, much of what is left is adjacent to built up areas, especially in Dorset. These lowland heathland fragments can be found across much of southern England on suitable soils. Much of the research on heathlands over the last twenty years has concentrated on the Dorset heaths, which are now almost all SSSIs and mostly within the Dorset Heathland SPA. While this report reflects the bias in the literature towards work in Dorset, the results have wide applicability to urban heathlands that are accessed by the surrounding urban populations for amenity and recreation whether in Dorset or elsewhere. This urban public access places considerable pressures on the heaths, for example through disturbance, wild fires, trampling, predation by domestic pets, pollution and enrichment.
