| Research Abstract |
The objective of this study is to show a sustainable management regime using selection cutting in natural mixed forests of northern Japan. Regarding the forest structural features, which can be an indicator of biodiversity, forest stand under selection cutting had less understory plant species diversity and deadwoods. On the other hand, selection stand had comparable ecosystem carbon stock with unmanaged stand. An individual-based forest simulation, based on parameters obtained in this study, suggested that it is required to reduce cut volume, especially in small-sized trees and coniferous species, by extending rotation period for maintaining structure and composition of original natural mixed forest.
