In our previous paper, we tried to formulate the relationship between unit cost or environmental load such as CO2 emissions and energy consumption per amount of logging residue and transportation distance. Generally larger scale transportation modes have an advantage over smaller scale transportation modes. The mode transfer from smaller scale to larger scale can be accomplished with an investment such as a setting of intermediate landing. In this report, the obtained formulation is applied to infrastructure development, i.e., improvement and/or construction of forest road network, and broad-leaved tree harvesting. Three mode of extraction was set: manual, winching, simple cable system. The levels of infrastructure development were assumed as two: one with 2m width road network for small-scaled system, and the other with 2.5m width road network for 0.20m3 class excavator based machines. Required data for calculating threshold harvesting volume have been identified.
