The purpose of this research is to study the effects of fire on vegetation and soil properties after the first growing season in Mt. Chiak, Korea [R.]. With the basis of important value of species in each stand, status of species was assessed for three categories; Increaser species, Decreaser species, and Neutral species. Biomass was 2.2 times higher on burned area than unburned. This indicates that biomass was remarkably increased after fire. To evaluate similarity, coefficients of similarity among communities were obtained, and correlation coefficients were also estimated. These indices showed that burned and unburned community were markedly different. B1-stand and B2-stand appeared most similar to each other among stands. Species diversity was greater in burned than unburned stands. Soil pH value and organic matter content in burned area were significantly higher than those in unburned area. However, soil water content was lower in burned area. Thero was no effect of burning on soil pH value and water conetnt at 15-20 cm depth of soil.
