Vegetation history of Kenbuchi Basin and Furano Basin in Hokkaido, north Japan, since 32 000 yrs BP

Abstract

Vegetation history was reconstructed from pollen analysis and 14C dates of almost continuous drilling cores obtained from two inland basins, Kenbuchi Basin in north Hokkaido and Furano Basin in central Hokkaido, north Japan. The newly identified cold age in Hokkaido, the "Kenbuchi Stadial', could be correlated to the Younger Dryas Stadial. In 8000-10 000 yrs BP, larch decreased and disappeared from Hokkaido. -from English summary
