3.5.4 The Forest Management Regime Map of Odai Town

Combining the maps showing sites for long rotation, short rotation, potential short rotation, and sites more suitable for conversion to broadleaved forests of C. japonica and C. obtusa, forest management regime map was developed. Consequently, 34.9% (3,649.9 ha) of the current C. japonica forest area (10,448.6 ha) was identified as suitable for long-rotation sites, while short-rotation sites and potential short-rotation sites occupied 3.2% (335 ha) and 13.0% (1,358.2 ha) of the forest area, respectively (Table 1). Sites more suitable for conversion to broadleaved forests accounted for 36.9% (3,855.5 ha) of the C. japonica forests, which occupied 1/3 of the area, similar to the long-rotation sites. The same tendency was observed for the C. obtusa forests: 35.0% (1,329.3 ha) and 33.0% (1,253.6 ha) of the C. obtusa forests area (3,800.4 ha), respectively. The relatively small area covered by short-rotation sites (3.6%) and potential short-rotation sites (15.7%) was also observed in the C. obtusa forests. The remaining area, 1,250 ha of C. japonica and 482 ha of C. obtusa forests (Table 1), had site conditions different from our investigated conditions and therefore could not be evaluated. These conditions need to be further investigated to complete the evaluation of the whole plantation area of Odai town .Table 1Area of sites evaluated to each forest management regime by species
