Proposing sustainable management methods for forest landscapes using retention forestry
Research grant
- Project Description
Verifying the effectiveness of retention forestry in providing a balance between producing timber and conserving biodiversity.
The future sustainability of Japan's man-made forests is in danger due to an imabalance in age structure and excessive tree-trimming for biomass resources. Recently retention forestry has been drawing attention as a forest management method which provides a balance between producing timber and conserving biodiversity, and mitigates the damage caused by clear-cut logging. This project aims to carry out Japan's largest-scale verification test of this method to clarify its effects on biota, and soil and water conservation functions. It will also assess the changes to timber production and the socially beneficial functions of forests when retention forestry is being widely implemented across a landscape, in order to propose forest management methods that sustainably realizes both timber production and these socially beneficial functions.

Background: 1996, left the Kyoto University Graduate School of Science doctoral program after completing course term. 1998, awarded doctorate of science. 1996, becomes a researcher at the Hokkaido Research Organization Forestry Research Institute and is given responsibility for researching methods for handling Yezo deer populations and conserving biodiversity in Hokkaido's forests. 2013, begins verification testing of retention forestry with co-researchers, carrying out research aimed at creating a balance of timber production from man-made forests and conservicng socially beneficial functions.
