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]

Geography

Topography
Creech Barrow Hill

The land within the Dorset Heaths rises to a maximum of 193 metres (633 ft) at Creech Barrow Hill,[5][6][7][8] but the average height is just 32 metres (105 ft).

Rivers

Major rivers include the Frome, Stour, Moors, Piddle, Sherford, Allen, Corfe and Dorset Avon.[3]

Main settlements

Other significant Satellite towns are Wareham, Fordingbridge and Wimborne Minster. The total population for the NCA was 446,296 as of 2001 with an increase to 466,626 following the 2011 census.
