Description
The rootlets of woody plant were torn under forest road construction.The authors made the assumption that the torn rootlets occured underforest road construction were as same mechanism as the torn rootletsoccured under mountain slope slide. This time, two planted conifers weremeasured. The results about torn rootlet diameter were as follows;
1. The summed values of the diameter class over 95% were 6mm class as Cryptomeria japonica and Chamaecyparis obtusa.
2. The distnbutions of the torn rootlets were varied with individuals and with species.
