| Research Abstract |
At the moment, the world’s forested area equivalent to more than two-thirds of the Main Island of Japan is lost every year due to illegal logging and slash/burn agriculture. The economic loss due to the illegal logging is estimated to be more than 10 billion USD, according to the OECD. In recent years, the U.S. and EU have introduced new laws to oblige timber industries to declare the geographic origin of their timber products. In this study, we developed two timber provenancing methods, where the origin is determined (1) by comparing tree-ring isotope series of unknown wood with those of known geographic origins, and (2) by comparing tree-ring isotope series with gridded global precipitation database. We succeeded to determine the geographic origin of Japanese and Russian timber at 60-300km accuracy.
