We investigated the effects of volcanic activity on growth of vegetation, and erosion rate by sheet erosion on Sakurajima volcano, based on field experiments. The results were as follows: (1) It became clear, based on the vegetation survey, that the number of tell trees became greater and the index of diversity increased with the decrease of the effect of volcanic activity on the experimental area. (2) Vegetation and the leaf-fall layer were restored with the decrease of the effect of volcanic activity. Moreover, the erosion rate by sheet erosion diminished with the decrease of the effect of volcanic activity.
