In order to reduce costs, cut down these trees and sustain the forestry industry, it is essential both to intensify forestry and increase the area of plantation per business unit. Therefore, it is necessary to prepare information on spatial distributions so that the resource distribution of plantation forests can be ascertained, and to use this information as a basis for appropriate and efficient forestry operations.
　Using the Geographical Information System (GIS) and public data to create a plantation forest map allowed the distribution pattern of plantation forests to be visualized, along with the relationship between plantation forests and topography. The introduction of spatial information can aid a variety of important decisions in forestry management. Along with establishment of sustainable forestry management, the diffusion of wood biomass energy is set to see further progress. Utilization of spatial information will also be useful for the mutually complementary use of wood biomass energy and other forms of renewable energy in the future.
