Expectations have been placed on scenic thinning in recent years in recovering the environmental conservation function and promoting recreational purposes of the increasing uncontrolled artificial forest stands. Although there have been recent reports on scenic thinning, there are very few examples of implementation. This study was conducted for the purpose of examining the possibilities of scenic thinning by investigating its impact on the place where Ito et al practiced it within the Shinshu University in 1992. We conducted the study by complete enumeration and vegetation survey of the tree and bush layers against the forest where scenic and ordinary thinning were carried out stand (scenic and ordinary thinning areas) and made a comparative review. As a result, there were no significant disparities of tree layers between both areas and no difference were found in the growth, which was expected in the scenic thinning area. However, with the bush layer, the average height of bush layer of arboreal vegetations was significantly taller with the scenic thinning and the differences in the distribution of tree height were great as well. This suggests that woodlands managed by scenic thinning can be lead effectively to multiple layered forest stands in comparison to ordinary thinning and indicates the forest's stability and the possibility of natural scenic cultivation.
