Abstract

Vegetation recovery process and amount of eroded soil were surveyed at the reforested stands in comparison with abandoned stands after forest fire. Reforestation works, especially terrace planting works, affected the successional pattern and species composition of postfire vegetation. Recovery of woody plant biomass at the reforested stands were more rapid than at the abandoned stands. In the early terms after reforestation, woody biomass was slightly larger at the terrace-planted stands than the natural-slope-planted stands. But, 12 years after reforestation, the woody biomass in natural-slope-planted stands were larger than that of the terrace-planted stands. Because vegetation recovery at the natural-slope-planted stands were progressed by both planted species and naturally recovered species; but the recovery at the terrace-planted stands were mainly progressed by the planted species. Amount of eroded soil at the natural-slope-planted stands were less than the terrace-planted stands and the abandoned stands. There was not significant difference of amount of eroded soil between at the terrace-planted stands and the abandoned stands.
