Studies of plant species diversity in plantation ecosystems were reviewed. Planting is markedly different from other forest management systems as differences in the species planted (e. g., exotic or native, evergreen or deciduous, conifer or broad-leaved) greatly affect plant species diversity in a stand or landscape. Stand develop- ment after planting promotes secondary succession, which involves invasion and regeneration by many species. While seed dispersal into a plantation by animals plays an important role in this process, the direction that the reorganization of the community takes is highly dependent on the degree of past disturbance, the distance from seed sources, stand age, and so on. There is large variation in the species diversity (including species richness and evenness) of plantations and other forest types. The species composition of plantations is usually much different from that of other forest types. Although many studies have examined timber production in plantations, little is known about the compromise between biodiversity conservation and timber production in plantations. Research on evaluating, conserving, and restoring species diversity and composition in plantations is required, with an investigation of the effects of plantations on plant-animal interactions, at both the stand and landscape levels.
