Historical logging and current successional status of old-growth Cryptomeria japonica forest on Yakushima Island

A Cryptomeria japonica forest on Yakushima Island, Japan, reveals distinct differences between its past and current successional stages due to historical logging practices from the 17th to 19th centuries. Analysis of stumps—preserved without significant decay—suggested two generations: pre-logging trees and those regenerated post-logging. Current monitoring indicates a decline in canopy conifer species, including Cryptomeria japonica, while understory broad-leaved species are increasing. The forest remains in an intermediate stage of secondary succession, with self-thinning processes still active among conifers. Succession dynamics vary significantly across plots, influenced by location and logging intensity.
