Abstract

In the forestry industry, revenues must be balanced with expenditures to improve efficiency. One way of achieving this goal may be to mechanize reforestation and harvesting operations. An analysis of revenues and expenditures showed that to maintain a balance at an interest rate of 3%, expenditures for reforestation would have to be brought down to 50% of the present level of 1.8-3.6 million yen/ha. This assumes a harvesting cost (not including transport costs) of 5,000 yen/m^3 (average cost of clear cutting and thinning), which is possible at favorable locations under the present forestry conditions. For this purpose, prototype systems using self-propelled reforestation machines and mechanized harvesters were investigated for a hypothetical annual operating time of 500 hours. The results showed that increasing the annual operating hours of reforestation machines could reduce current costs by 30%, but the 50% goal was not attainable.
