Abstract
Late Holocene vegetation and climate have been reconstructed from pollen spectra and plant remnants in peat core section near Lake Yarma, 1320 m asl (Oka Ridge, East Sayan mountains, southern East Siberia), and 14C dating. The reconstructed evolution of local and regional vegetation records alternating humid and arid climate cycles through the past 6 kyr. The reconstruction of short climatic episodes in the historic (Fernau) stage of glacier activity about 2750 years BP and in the Little Ice Age about 500 years BP have been obtained for the first time for this territory.
