Description:
We used GIS on a regional scale to estimate and compare supply potentials and costs of small-scale logging systems, a mini-forwarder and a 4-ton truck operated by private logging contractors, and manual logging and a light truck operated by individual forest owners, with the mechanized operational system of the Forest Owners’ Association. Total potential yields of timber and logging residues were estimated as 418,895 m 3 and 254,962 m3, respectively. The economic balances were estimated and available amounts were projected as supply potentials from profitable sub-compartments. As a result, available amounts of timber and logging residues were estimated at 376,466 m 3 (89.9%) and 203,850 m 3 (80.0%), respectively. Because their transport expenses were lower than for other systems the most profitable sub-compartments were operated by private logging contractors who sold logging residues at a plant. The profitable sub-compartments operated by individual forest owners were few because the extracting distances were usually greater than 20 m. Raising logging residue prices from 3,000 yen·m −3 to 4,080 yenn·m −3 or 6,800 yen·m −3 , and establishing forest roads, which reduced some extracting distances to less than 20 m, increased the number and area of profitable sub-compartments, and increased available amounts of logging residues.
