This is an investigation on the secondary vegetation and succession in the mixed forests destroyed by the severe crown fires on April 8, 1982. The results are summarized as follows: The floristic compositions in the investigated area are composed of 63 kinds of vascular plants. The biological type shows H-D_(1,4)-R_5-e, which is supposed to make a progress to the H-D_1-R_5-e type. Dominant species are Spodiopogon sibiricus(100.00)-Carex humilis var. nana(70.52)-Miscanthus sincnsis var. purpurascens(61, 06)-Lespedeza maximowiczii (57.53). Lespedeza maximowiczii is prevailing as the dominant species in this area. The species diversity(H￣) and evenness index(e) show 3.06 and 0.74 respectively, so that the species are various and shows uniform distribution comparatively in these communities. Degree of succession(DS) is 479 in the investigated area the value of which is comparatively higher than that of Chungcheongbuk-do area at the second year after fires. After the crown and trunk of trees were scorched by the crown fires, the pine tree (Pinus densiflora) died and the other species could be survived after sometimes. It seems that Quercus serrata, Q. dentata, Maackia amurensis, Lespedeza cyrtobotrya, Platycarya strobilaces and Lindera glauca are the fire resistant plants.
