Abstract

This paper shows the two examples of the fact that the hare's damaged rate to young Japanese cypress (Chamaecyparis obtusa) increases with the approach to forest edge of the stand. With the Second Yukawa study area (Wakayama Prefecture, western Japan), this fact was clear both in the case of the distance from all the edge and that of the virgin forest edge. Besides the more the elevation increased, the less the damaged rate of young Japanese cypress decreased perhaps because of the increase of snow depth with this study area. But with the Takatori study area (Nara Prefecture, western Japan), the former relations were not so clear chiefly as most plantations were damaged.
