PROBLEMS OF MID-POST-GLACIAL POLLEN ZONATION IN PART OF NORTH-WEST ENGLAND.

The article examines some problems of mid-Post-glacial ecology and chronology in the area south and east of the English Lake District in England. The post-glacial increase in pine pollen frequencies is discussed. The stratigraphical evidence for changes in water level during mid-Post-glacial times is detailed. Information on the radiocarbon evidence from Lonsdale is presented. A discussion is presented on the relation of pine maximum in Lonsdale to local habitat factors and the climatic implications of the pine maximum in Lonsdale.
