History of Dartmoor National Park

communities. Fire was the main method of clearing land, creating pasture and swidden types of fire-fallow farmland. Areas less suited for farming tended to be burned for livestock grazing. Over the centuries these Neolithic practices greatly expanded the upland moors, and contributed to the acidification of the soil and the accumulation of peat and bogs.

After a few thousand years the mild climate deteriorated leaving these areas uninhabited and consequently relatively undisturbed to the present day. The highly acidic soil has ensured that no organic remains have survived, but the durability of the granite has meant that the remains of buildings, enclosures and monuments have survived well, as have flint tools. It should be noted that a number of remains were "restored" by enthusiastic Victorians and that, in some cases, they have placed their own interpretation on how an area may have looked.

Standing stones

Numerous prehistoric menhirs (more usually referred to locally as standing stones or longstones), stone circles, kistvaens, cairns and stone rows are to be found on the moor. The most significant sites include:

Upper Erme stone row is the longest on Dartmoor and in fact in the world at 3,300 m (10,800 ft)

Beardown Man, near Devil's Tor – isolated standing stone 3.5 m (11 ft 6 in) high, said to have another 1 m (3 ft 3 in) below ground. grid reference SX596796

Challacombe, near the prehistoric settlement of Grimspound — triple stone row. grid reference SX689807

Drizzlecombe, east of Sheepstor village – stone rows, standing stones, kistvaens and cairns. grid reference
