The structure and causal factors of a forest line, the boundary between mountainous forests and non-forest vegetation, were studied on Mt. Daisen, Japan, to clarify the long-term influences of volcanic evolution on vegetation. A distinct forest line formed at between 1100 and 1300 m elevation, which coincided with the geological boundary of the lava dome and talus deposits. No forest stands were able to develop on the summit lava dome because of poor soil development, and the position of the forest line was controlled not by macroclimatic or topoclimatic conditions but rather by the immature soils on the lava dome that formed during the late Pleistocene to early Holocene.
