Abstract

<p>The following study was performed for the purpose of verifying how plant diversity changed by tree species conversion from coniferous plantation to broad-leaved forest. We investigated changes in the composition of plant species over a 30-year period in broad-leaved forest in the warm-temperate zone, which regrew after meteorological damage. The total number of species increased for three years after the disturbance, but subsequently decreased. To analyze the changes in species composition from an ecological perspective, the species were typed according to habitat classification. Lucidophyllous forest species increased throughout the study period. Non-forest type species increased rapidly in the early regrowth stage and then decreased. Overall, in the regrowth broad-leaved forest, the plant species increased markedly in the early regrowth stage due to a temporary increase in non-forest type species caused by disturbance, but these species then decreased with time. To conserve diversity in forest management, we must be aware that plant diversity in regrowth forests depends on non-forest type species.</p>
