Abstract

A modern pollen rain study along an altitudinal gradient in the Bale Mountains National Park (Ethiopia, East Africa) was carried out from 1580 m a.s.l. to 4110 m a.s.l. The contents of seven artificial pollen traps from seven plant communities corresponding to different altitudinal belts were investigated. Pollen spectra reflect the dominant taxa of plant communities in most cases. However, the pollen of some widespread plants was underrepresented in the spectra due to low pollen production, flowering rhythms, and local features of the vegetation cover. Long-distance pollen transport was noted in all plant communities, but it was most pronounced in open communities.
