An Investigation of Vegetation Changes by Pollen Analysis of Forest Soils

摘要

Vegetation changes were investigated by pollen analysis of forest soils under a temperate mixed forest in the southwestern part of the Tsurugi Mountains, Shikoku, Japan. The two soil profiles recorded vegetation changes that were caused by cutting practices on a large scale in the early Meiji period (the late 19th century). The previous vegetation type appears to have been an Abies firma-Tsuga sieboldii Forest containing various broad-leaved trees, although Abies firma and Betula grossa Are dominant in the present-day vegetation.
