Outline of Final Research Achievements

Retention forestry, in which trees are left unlogged at harvesting events in order to conserve biodiversity in production forests, has recently received social concerns. In this study, we investigated the effects of retention forestry on biodiversity.
We found larger number of species in retention stands than in unharvested stands. We also found that post-harvesting plant succession is largely driven by competition among neighboring individuals.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は、保残伐施業をはじめとする林業活動を行ったときに、森林に住む生物がどのように反応するかを理解・予測するのに役立つ。これまで我が国では、主に森林景観内に一定面積の保護林を区分け(ゾーニング)することによって、生物多様性の保全に配慮してきた。これに対し、保残伐施業は同じ場所で木材生産と生物多様性保全を両立させることを目指す新しい施業方法であり、本研究で得られた成果はその発展に寄与すると期待される。
