Research Abstract

To estimate forest area damaged by mammals accurately and reasonably, damage to newly-planted Cryptomeria and Japanese cypress by hares, sika deers and serows were investigated in Nara and Wakayama prefecture.
Damage type Damage types could be divided mainly into two types,l) cutting of stem and branches at the lower part and 2) peeling bark.
Growth of trees After one year, effects of damage by hares and processor recovery were checked. Of the trees with cutting type damage 14.4 % had normal growth, 23.6 % had withered And 33.4 % had extremely abnormal growth.
Recovery of tree form In case of about 90 % among damaged Cryptomeria, a healthy branch under the portion damaged grew upwards and become stem. Removal of stem-shoot less than 30 cm had no effect on the height growth because of upright growth of a lateral branch.
Estimation of area damaged Area or number of trees damaged were estimated by different methods, 1) survey of the major axis and the minor axis, and 2) those of 5 m or 10 meter interval. However, due to the high damage rate, accuracy among the methods are not clear.
