To characterize the root strength properties of red pine tree by elapsed years after forest fire, we measured and
analyzed the tensile force and strength of the roots. The mean tensile force was a decrease of 51 % and 71 % compared with the original root tensile force within 2 and 3 years after forest fire, respectively. 67% of the tensile strength of original root was lost within 2 years after forest fire and 74% was gone within 3 years. The rate of tensile force and strength deteriorations in larger roots was increased more than that of finer roots by root diameter classes and elapsed years after forest fire.
