| Research Abstract |
Japanese forestry is now getting into a new stage of productivity, taking an opportunity of introducing the high-performance machine, contricuted by a part of logging companies and forest owners. At present two types of forest management may be set up as follows.
1. Consistent management : This type of management is taken by forest owners who can afford to manage all the process from afforestation to log production. Many examples can be seen in old forestry regions, such as Kinki area, where expensive pillars are produced. This type is diveded into two sub-types such as 'large scale consistent management' using employed laborers, large machines, and high-density forest road system in high-standard and 'middle scale consistent management' using individual family laborers, small machines, and high-density forest road system in low-standard.
2. Efficient managemaent for mass production : This type of management is taken by large scale sawmills, adopting high-performance machines. Many examples can be seen in the forestry regions such as Kyushu and Shikoku areas, where man-made forests grows fast, national forests are moderately distributed, and there are many middle-scale forest owners.
Log production with high-performance forestry machines is, however, often associated with large scale clear cutting, which is apt to cause deterioration of the forest resources.
Forest policy will be recommended to restore rural communities trough promoting to make use of the local resources, to manage forest resources properly through the institutional reconstruction of forest owners cooperatioves and the promotion of forest management by middle-scale forest owners, and to introduce high-performance forestry machines into the operation of thinning and selective cutting.
