A pollen diagram of the Moorer Busch near Grevesmuehlen (NW Mecklenburg, NE Germany) from the legacy of Franz Fukarek

摘要

A pollen diagram from the Moorer Busch near Grevesmuehlen (NW Mecklenburg, NE Germany) from the legacy of Franz Fukarek covers considerable parts of the Weichselian Lateglacial and the Early/Middle Holocene. During the Lateglacial Betula/Pinus forest phase (Allerod), birch forests dominated the upland in which pine played a minor role. During Open vegetation phase III (Younger Dryas) open vegetation types prevailed, though observations of stomata attributable to Pinus confirm that pine trees were present around the study area. During the Early Holocene again forests of birch and pine dominated the upland, in which later Corylus invaded and became dominant. The middle Holocene section of the pollen diagram shows hardly fluctuating values of pollen attributable to Corylus, Ulmus, Ouercus, Alnus, Tilia, Fraxinus and Hedera, indicating that rather stable deciduous forests prevailed. During the beginning of this vegetation phase, the basin terrestrialised and Sphagnum peat was formed at the cored location that towards the end of this phase graded into a Sphagnum-Ericales peat. The pollen section ends shortly above the mid-Holocene elm decline: younger peat deposits have been destroyed by peat extraction after A.D. 1800.
