Outline of Final Research Achievements

In the world’s advanced forestry countries, compatibility between the environment and economy, and the contribution to the local society are taking root as major concepts of forest management. The substantial development of the Working system which supports such concepts is awaited in Japan as well.　This study was performed to establish the Shelter-wood system applicable to the Chamaecyparis obtusa forest, and to find out the “Regeneration Period Model” suitable for its wood property tree species characteristics. The study showed that the Seeding cutting should be conducted before forty to sixty stand age, and the Removal cutting should be started around five years from the Seeding cutting, ideally less than three times and in the span of about twenty to thirty years. In conclusion, the Regeneration period of the Chamaecyparis obtusa should be no longer than thirty-five years, including one Seeding cutting and the following Removal cuttings, without the Preparatory cutting.
