| Outline of Final Research Achievements |
In the mountainous heavy snowfall region, we examined the possibility of sustainable beech forestry, due to effective estimation of beech volume in stand scale, measurement of available beech round timber from stand volume, criteria for sustainable harvest of selective logging and thinning, furthermore, ecological character.
On GIS system, we cut the study area of 700 hectares into the mesh size of 50 meters and then estimated stand volume in each mesh from an equation with tree crown area measured on the aerial photos. Following the total stand volume, we proposed a group selection system in an analogous manner to primeval forests recurring in cycle of one hundred years. Intense thinning should be effective for growing sufficiently of the high dense seedlings regenerated in advance. We also showed that the trees with hollows should be left for nesting site as much as possible in a harvest stand for the biodiversity forest management.
