A Case Study in the Non-national Sugi Plantation Forests in Miyazaki PrefectureIchiro FUJIKAKE2019 Volume 72 Issue 3 Pages 1-14

JOURNAL FREE ACCESSLog production has been expanding so rapidly in recent years in Miyazaki Prefecture where Sugi (Cryptomeria japonica) grows fast, that the sustainability of production is questioned. This study proposed a method to simulate the sustainability of log production, and applied it to the non-national Sugi plantation forests in the prefecture. With this method, how long a target log volume can be sustained in each watershed is calculated under the presumptions on the replantation rate and the unable-to-harvest forest rate. The effects on the length of sustainable production period of some policy options such as replantation rate improvement, recovery from unable-to-harvest forests to harvestable ones, and production volume share between watersheds are also examined. The results showed that the sustainability is in a critical level in some watersheds so that some policy options need to be realized, from which it is considered that such a method to simulate and examine policy options will be an effective tool for local forestry administration at a time when log harvest is increasing nationwide.View full abstractDownload PDF (656K) -
