The paper is investigation of the secondary vegetation and succession at the forest fire area in Mt. Palgong The survey was carried out from April, 1981 to September, 1982. The floristic compositions were as follows: 50 families, 116 genera, 127 species, 15 varieties and 3 formae(145 kinds). Among them, the floristic composition of the pine floor vegetation of the unburned area was 43 families, 80 genera, 88 species, 10 varieties and 1 forma(99 kinds), and that of the secondary vegetation after forest fire was 46 families, 106 genera, 120 species, 14 varieties and 3 formae(137 kinds). Index of similarity between the burned and unburned area was 0.77. The biological type succeeded in H-D_1-R_5 type, and the erect form(e) was prevailed. Carex humilis var. nana, Miscanthus sinensis var. purpurascens, and Lespedeza cyrtobotrya were dominant species in the B_1 and B_2 area of the seventh year after forest fire. In the degree of succession, species diversity, and evenness index, DS, H, and e of the B_1 area were higher than those of the B_2 area. In the soil properties, it assumed that pH, total nitrogen, and available phosphorus of the burned area were nearly recovered to those of the unburned area.
