Forest vegetation of Northern-East Podolia in Late Holocene (based on pollen analysis data)

The results of the palynological and radiocarbon investigation of three peats from North-Eastern Podolia (Khmelnytskyi district, near v.v. Pashkivtsi and Pechesky, Dobrohorscha, Heletyntsi) are presented. The age of the sediments is Late Holocene, sub-Atlantic period (SA-2, Iron era by archaeological scale), so they have preserved the information about changes in vegetation cover over the last 1500 years, when human impact on the environment already existed and gradually intensified. The article is analyzed the dynamics of Holocene forest vegetation on the North-Eastern Podolia. The main regional components of the forests were Pinus sylvestris, Picea abies, Betula, and sub-regional were Ulmus sp., Carpinus betulus, Ouercus sp., Tilia cordata. Linden-oak, hornbeam-oak forests and forest communities with elm are spreading closer to our time. A common trend in the share of pollen of trees relative share of herbal plants since the beginning of the formation of deposits to the present is showing. This reduction of forest areas could occur as a result of cutting. For all of three peats observed changes in common share of the total pollen broadleaf trees, the early formation of deposits, it is 2.9%, then reduced to 2% and closer to our time again significantly increased to 6.5%. This correlates with a decrease of content of Pinus and Picea pollen grains. Perhaps there was an increase area of deciduous forests with participation of elm and oak-linden and hornbeam-oak forest.
