The improvement cutting of coppice was carried out in heavy snow mountain slopes, together with planting and construction of a simple supporting structure for glide of snow cover. To clarify the effect of the operation, the distance of glide was measured, as well as the state of the sprouts from the cut coppice and the height growth of planted stock. After the operation, the distance of glide could be suppressed to approximately 2 m on the steep slope. This fact suggested the efficiency of the supporting works. Since stumps used as the supporting structure are sprouting, they can be effective for a long term. The height of planting stock exceeded the maximum snow depth after 5 years. The stock will be able to control the glide of snow cover if the survival rate and the growth rate maintain their present status.
