Our reconstruction of vegetation changes from the well-dated pollen records since the early Holocene at Komatsubara peat bogs, Mt. Naeba, advanced our understanding vegetation history on the sub-alpine zone. The pollen records from the Shimo-no-shiro (1,330m a. s. l.) and Kami-no-shiro (1,570m a. s. l.) peat bogs indicate that Abies pollen appeared continuously from ca. 5,000-4,500 cal BP, at least. Additionally, our spatio-temporal comparison of pollen records from different altitude sites on Mt. Naeba shows that the distribution of Abies mariesii moved gradually to a higher altitude from the middle Holocene to the present. It is highly possible that the geomorphological environment and soil development on the alpine area influenced the colonization of Abies mariesii.
