Abstract
The paper presents the reconstruction of Holocene dynamics of forest fires and its influence on vegetation in the central part of Meshchera Lowlands. The studies are based on macrocharcoal and pollen analyses and radiocarbon dating of peat deposits from the peatland Studencheskoye. According to obtained results, changes in the structure of the plant cover were largely determined by fire regime during the Holocene. In the period of high forest fires intensity (~9200 - 6400 cal. (calendar) years BP) the study area was occupied by birch-pine forests. The role of spruce and broad-leaved species in forest stands was increased in the period with low frequency of forest fires (~6400 - 1400 cal. years BP). The influence of fires on vegetation increased after 1400 cal years BP due to human impact. The obtained results show that periods of increased fire frequencies occurred before the human occupation of the area and were determined by climatic reasons.
