Abstract

Based on AMS 14C dating, re-identification of plant macrofossil, and pollen analysis of samples that were collected at Shirotsuki-Takatsu, Ooda, Shimane Pref. (200 m a.s.l.) by Dr. Shigeru Miki, paleovegetation in the last glacial maximum (LGM) in the northeastern Chugoku District, southwestern Japan, was reconstructed. A coniferous forest dominated by Tsuga diversifolia and Picea jezoensis var. hondoensis with Abies veitchii, Pinus koraiensis, Picea sect. Picea and Chamaecyparis obtusa was distributed in a valley in Shirotsuki-Takatsu during the LGM. According to the earlier studies, temperate coniferous forest was reconstructed as the most dominant forest biome during the LGM in low altitude areas along the Sea of Japan in the Chugoku District. Besides, the present fossil record indicates that a subarctic coniferous forest common with that of the present subalpine zone in central Japan was distributed in low altitude areas. A review of last glacial maximum pollen profiles from the Chugoku District showeded that vegetation was affected by geomorphology surrounding research sites rather than by altitudinal gradient, and subalpine trees dominated often in areas at lower altitudes surrounded by slopes, and temperate broadleaved trees occurred commonly in areas at higher altitudes surrounded by wetland and gentle slopes. Our research demonstrates that a re-investigation of plant macrofossil collections stored in museums enables detailed paleovegetation reconstruction with high resolution dating.
