Abstract
Modern pollen trapping data, obtained in the years 1997 and 1998 from 32 modified Tauber traps in different landscape regions of Estonia, are discussed. Preliminary analyses have revealed great variability of pollen influx values. The influx of arboreal pollen (AP) in 1998 was in general three to four times higher than in 1997. In both years, Betula and Alnus pollen dominated, accounting for up to 70% of total AP. The share of non-arboreal pollen (NAP) was much higher in pollen traps than in samples from lake and bog sediments and this reflects the influence of very local vegetation. Cerealia-type pollen influx values are closely correlated with the distance of the study site from the nearest field and also show the existence of some background values in the atmosphere.
