ISOPOLLEN MAPS FOR POLAND: 0–11000 YEARS B.P.

Abstract

S ummary Isopollen maps were first constructed by Szafer (1935) to illustrate the post‐glacial history of Picea and Fagus in Poland. New more detailed isopollen maps for 1000‐ or 500‐year intervals based on 64 pollen diagrams, many with good radiocarbon‐dating control, are presented for Picea abtes, Ulmus, Corylus avellana, Quercus, Tilia, Alnus, Carpinus betulus, Fagus sylvatica , and Abies alba . These maps illustrate the changing relative importance of these pollen taxa over the last 11000 years and suggest the possible routes of migration of the tree taxa concerned. The complex and diverse migrational history of these major Polish forest trees is demonstrated. The major migration routes appear to have been from the south‐east, south, south‐west and across the middle European lowlands from the west, north‐west and north‐east.
