Abstract
Results of the palynological analysis of peat profile Fomka in the northern part of the Kas river catchment area (Kranoyarsk Region, Russia) are presented. Research based on pollen data reveals changes in forest composition during the last 8 kyr. Forest with predominance of birch (Betula sect. Albae) and Siberian spruce (Picea obovata) spread between ca. 7.5 and 8.5 kyr BP; with birch, Siberian spruce and Siberian fir (Abies sibirica) between 6.85 and 7.5 kyr BP, and with Siberian spruce and Siberian fir – between 6.6 and 6.85 kyr BP. Prevalence of Scotch pine (Pinus sylvestris) and birch in arboreal composition was revealed from ca. 4.4 till 6.6 kyr BP. Siberian pine (Pinus sibirica) with Scotch pine and birch spread from ca. 4.4 kyr BP onwards in the Kas river basin.
