Abies-dominated forest of the Latest Last Glacial in Southwestern Hokkaido: Reconstruction from Wood and Pollen Fossils

摘要

The latest stage of the Last Glacial vegeta- tion was reconstructed from wood and pollen fossils buried under Nigorikawa tephra (about 12,000 yrs BP), southwestern Hokkaido. Ob- tained wood fossil assemblages (including carbonized woods) were composed of Abies, Picea, Betula, Larix, and Rosa. Abies could be assigned to Abies sachalinensis and Larix could be Larix gmelinii, based on previous plant macrofossil studies. macrofossil studies.
