Abstract

This study aims to obtain information of the potential supply of natural forest resources of Japanese cypress required to maintain the wooden heritage buildings. Prescribed conditions to maintain important cultural buildings are strict and require using the same building technique as well as using the same tree species of the same quality. To investigate the potential to ensure sustainable materials, it is necessary to estimate the forest resources that reflect the information on demand-side. A case study of Donjon of Ozu castle in Ehime prefecture, we calculated the necessary forest resources to build a Donjon based on height-diameter curve equation and taper curve equation of methodology technique of forest measurement. As a result, it is estimated that the construction of Donjon requires about 53.6ha forest resources. In addition, the required area could be 5 times larger than the estimation if we took account of the cutting ratio in forestry management.
