摘要
Lake sediment sequences of the small Lake Nadbannoye on Anzer Island (Solovetsky Archipelago, White Sea) have been analyzed. Lake located at the highest elevation of 20–21.5 m a. s. l. relative to other lakes studied on the island. Based on the results of pollen analysis, the dynamics of vegetation from the Late Glacial period and during the Holocene was traced. In this research, the special attention is paid to the dynamics of tree species, which are an important component of the vegetation cover in the study region. Changes in the composition of tree species here are the basis for the identification of pollen zones. Throughout the entire studied period, the forest-forming species was birch, with pine being of secondary importance. A low content of spruce was noted, which is not typical for other sites of the White Sea region. Broad-leaved species clearly mark the boundaries of the Atlantic period. Anthropogenic influence has been recorded since the Subboreal period, which is confirmed by the dynamics of tree species, as a result of deforestation as a result of human activity. Radiocarbon dating confirms the pollen data.
