Outline of Final Research Achievements

I developed a new method for predicting site index of sugi and karamatsu planted forests. Precise observation of site index requiring a high cost has been needed to develop site index prediction model. I applied a new statistical technique to improve this point. Site index models developed by this new method had enough accuracy comparing to the conventional high cost method. This new method provides low cost approach for modeling site index and will contribute to achieve more appropriate planted forest management.
