Late Glacial vegetation changes in the Kostroma Volga region based on pollen study of Lake Chukhlomskoye bottom sediments

Abstract

The article presents the results of a palynological study of Lake Chukhlomskoye bottom sediments. Pollen analysis in combination with the results from ¹⁴C and ¹³⁷Cs dating made it possible to reconstruct the main stages of changes in plant communities in the Kostroma Volga region at the end of the Pleniglacial and during the Late Glacial: 19.5–16.9 cal. ka BP – periglacial steppe, 16.9–14.7 cal. ka BP – birch periglacial forest-steppe, 14.7–12.7 cal. ka BP – spruce and birch-spruce forests and open woods with periglacial-steppe and meadow communities, 12.7–11.7 cal. ka BP – birch periglacial forest-steppe with rare participation of spruce.
