Abstract
Vegetation history was reconstructed from phytolith assemblages and macro-charcoal from sediments in the Ooshiburi-dorine on northern Akiyoshi-dai Plateau, Yamaguchi Pref., Japan. Eleven phytolith morphotypes were identified from samples, and phytolith zones were divided into zones I and II. Phytolith assemblages and charcoal concentrations in the sediments indicate that arboreal vegetation existed with abundant Sasa on the forest floor at study sites in zones I and II corresponding to the period of the last 200–300 years and that Miscanthus and Bambsoideae grassland was developed under the influence of human disturbance such as fire.
