Extent

According to Natural England, who have designated the Dorset Heaths as National Character Area 135, the heathlands cover an area of 61,662 hectares, whose boundary runs from Bockhampton and Warmwell in the west via Wimborne Minster to Fordingbridge in the far northeast. It then turns southwards to Hengistbury Head, before following the coastline to Studland and Brownsea Island then finally heading westwards - north of South Purbeck (with the Purbeck Hills) and the Weymouth Lowlands - to the Warmwell area.^[3]

Character

The character of the Dorset Heaths contrasts strongly with its neighbouring natural regions. Undulating lowland heath with heather, pines and gorse alternates with exposed, open, large-scale farmland, woodland and scrub. Blocks of conifers form locally prominent landmarks. Apart from the major Poole-Bournemouth-Christchurch conurbation on the coast, much of the area is sparsely populated with scattered settlements and a few small villages and towns. Valleys are flat-bottomed and open with floodplain pastures. There is an outer perimeter of low, rolling hills marking the transition to chalk downland.^[4]
