Research Abstract

This study was investigated so as to present the way of reorganization of the Sugi (Cryptomeria japonica) forest working systems in Tohoku district. The results of this study are as follows.
1) In Sugi working system, it is desirable to change itself from the treatment of monoculture forest to the treatment of mixed forest.
2) In the traditional working system of monoculture forest, there are many afforestational techniques that should be improved, the method of planting area and composition, final cutting age, cleaning cutting and thinning, and so on.
3) Accordingly development of the stand canopy clearly is divided into four different stages on the bases of the changes in the net production rate.
4) Row thinning operations by a mobile tower-yader was preferable to select thinning operations in terms of labor productivity, but was not preferable in terms of cost. The intensity of soil disturbance caused by row thinning operations was lower than by select thinning operations.
5) Because of the long-term depression of forestry, the Sugi forest management practice is mostly supported by the rural farm household labors.
