A Seires of pollen diagrams from upland Dartmoor are presented. They cover the Post-glacial period from early zone IV to the present day but the Late-glacial is not represented.
The extension of forest cover over the region is deduced and an early, pre-Ulmus decline of forest is noted, preceding more widespread clearance in zones VIIb and VIII The immigration of Alnus is deduced to be more rapid when biotic influences are present. The composition of the past forest is discussed in the light of the present distribution of Quercus spp. In the region and the probable, local presence of Fagus is postulated in zone VIIB and later. The parallelism of the Plantago and Fagus curves lends support to Godwin's suggestion that the immigration of Fagus is bound up with the movements of prehistoric man.
