Recently in Japan, investigators have recognized the correlation between timber cutting and increased frequency of landslides with time after logging. In order to find out of mechanism on biotechnical slope stability by plant root systems, the tensile strength of individual tree roots was tested with a modified root specimen. Because the tensile strength of roots may be closely related to the root diameter and even to the tree species, the variety of tensile strength of roots between several species was discussed by comparison for hillside revegetation works. On the other hand, the mechanical behavior i.e., the characteristics of load-extension curves of root specimen and the root morphology were also discussed.
