Research Abstract	To elucidate the mechanisms of bark-stripping by sika deer with a viewpoint of food selection, and to construct the models predicting the bark-stripping damage, I investigated and analysed the relationships between the occurrence of bark-stripping and environmental factor in plantation and natural forest. The results of the research at plantation showed that: The altitude and slope degree had negative effect for occurrence of bark stripping damage. The area ratio of neighboring grassland had positive effect. The probability of suffering damage increased with a Hinokisypress than a Sugi cedar. The results of the research at natural forest showed that: each tree size, ratio of Sasa bamboo cover on forest floor, and using frequency of deer had positive effect for occurrenceof bark stripping damage.
