Outline of Final Research Achievements

The whole tree harvesting by the tractor and winch system realized high productivity within the maximum skidding distance 30 m even for qualitative thinning. It is important to decide the chipper size according to the size of business. By combining the merits of small scale forestry and the low price chippers, a simple and low-cost chip supply model could be established. This system could create employments in local community. Forest road network planning at Takayama district, Gifu prefecture, showed the stable annual chip supply of 1,237 t. In the rubber wood biomass supply chain in Thailand, the Google Maps API was applied to find the shortest route between rubber plantation and sawmill.
