Outline of Final Research Achievements

A simulation system, based on pre-existing models, was used to investigate
and visualize the solution space for optimizing forest managementplanning. The simulation system used existing forestry profits estimation models to test the outcomes of different crop rotations by previous studies. This study has investigated and visualized the solution space optimized for forest economics using various combinations of short and long rotation silvicultural practices implemented at a local scale. Based on the simulations, optimization of the plans was formulated under the forestry scale of compartment and total level. The differences of forestry profits, labor requirements and timber volume depending on the intensity of silvicultural practices were analyzed. The simulation system is also useful for sustainable forest management under the Japanese forestry planning system.
