Annual pollen-accumulation rates (PAR) of Fagus (beech) obtained within the framework of the Pollen Monitoring Programme (PMP) were analyzed in pollen traps along a N-S transect from the Baltic Sea to the Black Sea in different European vegetation units. Most time series are 10 or 11 years long, some are 5-16 years long. Inter-annual fluctuations in Fagus PAR were analyzed and compared with seed mast years. Years with high Fagus PAR and others with low Fagus PAR occurred most frequently in parallel within each region and often in two neighbouring regions. 2006 was exceptional as it had a very high Fagus sylvatica pollen deposition in all study regions and it was also a mast year. Regional occurrence of beech-dominated forests was reflected by a Fagus PAR of ca. 1,400 grains cm-2 year-1, local abundance very close to pollen traps by ca. 2,400 grains, small patches of forest with admixture of Fagus by ca. 170-220 grains, and scarcity or absence of Fagus by ca. 40 grains or less.
