Dartmoor is an area unequalled in Southern Britain for its collection of visible remains of human occupation covering some 4000 years.
The preservation of these remains has been due to their existence in a large area of high moorland, but little disturbed by later agricultural or other activities, that involve the breaking of the soil.
The nearest comparable collection is on the western slopes of the mountain mass of Merioneth in North Wales.
But Dartmoor, which lies nearer to the Continent from which successive groups of settlers came, is likely to yield the more valuable information.
Scientific study requires that the area be considered as a whole.
Irreparable damage has already been done in the part farther north, including the Tavy Valley, and it is therefore the more necessary to preserve what remains. (2) The Plym valley is one of the richest areas in the whole of Dartmoor in respect of antiquities. Detailed evidence is being Submitted on behalf of the Council of British Archaeology and the Devon Archaeological Exploration Society.
