The area that we now call Dartmoor is a site of huge historical importance, with over 500 sites referenced by Jeremy Butler and over 3000 stone and 6000 wooden round houses estimated by Petitt. The general consensus is that there are many more sites to be discovered, with extensive ancient field boundaries or Reaves dividing up the land, hinting at the type of existence that these people lead. However, radiocarbon dating has shown that most of the Reaves were built within a 200 year period; and only in use for between 200 and 400 years. The abandonment of the Reaves and the upland moor has been put down to Geographical issues such as a change in climate at the time, a drop in temperature and an increase in dampness, however there are other more minor factors that also contribute to the departure of man from the moor, and the current lack of extensive settlement in the area today.
