The mortality rates of stumps varied significantly with species and life-form spectra, but not significantly with position, direction of slope. The relationship between mortality and D.B.H remained unclear. Of all species, 2 species had no living stumps, adversely 16 species had no dead ones, and 44 species had not only living ones but also dead ones. 37 species had the mortality rates equal to or below 20.0%, 16 species had the mortality rates higher than 20.0% and equal to or lower than 50.0%, and 9 species had the mortality rates higher than 50.0%.
