Changes in stand structure and tree species diversity by forest2025 · 記述言語： 日本語 掲載種別： 研究論文（学術雑誌） 出版者・発行元： Journal of Forest Research The intensive exploitation of subtropical forests makes it essential to understand how secondary forests can be restored. We aimed to elucidate the restoration process of stand structure and tree species diversity in subtropical secondary forests with respect to topography. We censused trees in thirty 400-m<sup>2</sup> plots established in evergreen broadleaf forests aged 31–147 years old on ridges and in valleys of Amami Ohshima Island, southwestern Japan. We analyzed changes in stand structure, tree species diversity, and tree species composition with age. On ridges, an increase in tree size with forest age was associated with both vertical stratification and decreased tree density. Although young stands were dominated by tree species that readily sprouted, the recruitment of other species increased with forest age, in turn enhancing tree species diversity. In valleys, canopy trees reached maximal height by 31 years after clear-cutting, and recruitment of tree species was limited despite forest age. As a result, we observed no vertical stratification and a decrease in tree species diversity. However, basal area, an index of forest biomass, increased with forest age. Our findings indicate that forest management should differ between ridges and valleys. Ridges showed the gradual restoration of forest structure and tree species diversity, while, in valleys, there is a dilemma for the restoration of forest biomass with the decrease of tree species diversity. Additionally, large trees require long growth periods even in valleys. Forest managers should protect some forests in perpetuity to repopulate the surrounding forests as they are exploited.
