Acidic soil is ubiquity distributed in Japan and it effect on the civil engineering structures because of its chemical properties. In this study, the distribution of pH in 2013 and 2018 in small slope area at Shiga Kogen was compared to clear the change in soil pH caused by the temporal change over 5 years, and to examine the relationship with the plant restoration. Restoration was confirmed middle and lower parts of slope, and the pH of surface soil in the surrounding area was approaching neutrality in 5 years. It was considered that acidity was declined by hold of neutral soil by plants and soil formation by deposition of defoliation.
