Soil erosion of a logged-over tropical forest, Pasoh, Negeri Sembilan

This study was conducted in the area of logged-over tropical forest in Pasoh Forest Reserve, Kuala Pilah, Negeri Sembilan. The attempt of this study was to investigate and observe soil erosion of a logged-over tropical forest. Soil erosion was monitored by using erosion pins at five unbounded research grids in a 100 m x 100 m research plot for 154 days. The occurrence of soil erosion and soil deposition were observed. Among the research grids, the maximum soil erosion was 14.6 mm and the maximum soil deposition was 7.2 mm. The forms of soil erosion that occurred were sheet erosion and splash erosion. Generally, the pattern of soil erosion varied significantly between one location and another within the plot. However, the pattern of erosion at one location did not change significantly with time
