THREE FLANDRIAN POLLEN PROFILES FROM THE TEITH VALLEY, PERTHSHIRE, SCOTLAND

S ummary Deteriorated pollen grains have been recorded from Flandrian sediments in three sites near Callander in Perthshire, and diagrams are presented of deteriorated pollen as opposed to the overall pollen totals discussed in the previous paper. The problems of interpreting records of deteriorated pollen are discussed, a format for pollen diagrams conveying detailed information on deteriorated grains is introduced, and the palaeoenvironmental implications of the records are considered. It is shown that major changes in deteriorated pollen totals are common to all three diagrams, with low percentages in the early Flandrian, and pronounced increases in deteriorated totals coincident with the Corylus decline at each site. It is suggested that similar studies at other sites in northern Britain may prove these trends to be consistent features of Flandrian pollen diagrams.
