Abstract
Nineteen radiocarbon dates were obtained from bogs and outcrops around Lake Baikal in the Tandetron AMS facility, Dating and Materials Research Center, Nagoya University. These dates indicate that the record from bogs and outcrops around Lake Baikal extends back to the Last Glacial Maximum or the last interstade and make it possible to make the correlation of reconstructed vegetation in each sites. The outline of the taiga forests history is as follows. In the southeastern shore areas, spruce became dominant from the late-glacial to the early-Holocene and fir increased in the early-Holocene. In the mid-Holocene, pine trees (P. sibirica and P. sylvestris) were widespread in this area. On the other hand, in the northeastern inland region of Lake Baikal, larch has been a main component of the forests since the early-Holocene. We will make more radiocarbon dating of sediments in the northeastern shore area of Lake Baikal.
