Later Neolithic Woodland and Regeneration in the Long Barrow Ditch Fills of the Avebury Area: The Molluscan Evidence

Modern data on molluscan migration rates are applied to the sub-fossil record obtained from Neolithic long barrow ditch fills of the Averbury region. It is demonstrated that it is theoretically possible to consider the maximum and minimum distances of woodland from a number of long barrow sites. The problems and potential of such calculations are addressed.
