The vegetation developmet of the largest montane oligo-ombrotrophic raised bog situated on the Modrava plains has been evaluated by pollen analysis. In the Late Glacial the mire developed around a spring close to the melting glacier on open heliophytic tundra. Propagation of woodland with birch, pine and willow is evidenced in the Boreal. In 8300BC an abrupt climatic change was indicated by furter invasion of trees hazel, spruce, oak, eml and ash. Spruce became the most importat species in taiga landscape. Beech expanded massively, replacing hazel and pine in 5200BC. Dense, high-montane mixed spruce-beech woodlands developed. In 4900 BC fir expanded gradually, whereas pine declined. In 2200BC spruce invaded the highest evevations. The woodlans, where fir became the most abundant climax tree, were dense with closed canopy. Human activity related to the Bronze Age (2200-775 BC) at lower elevation is shown by regular occurence of cereal pollen and indicators of woodland oppenings. The main colonization with intesifying land use occurs in the Middle Ages.
