| This is a report on the recovery of vegetation and secondary succession in the burned area studied from April, 1990 to April. 1991. The forest fire occurred in a part of Mt. $Kv{u}mo-san$ on April, 1986 and the pine forest and its understory vegetation were burned out completely. The floristic compositions of burned (B) and unburned (U) areas were composed of sixty eight and thirty one species (vascular plants), respectively. These species were divided into invaders (47 species), increasers (15 species), deceasers (3 species), neutrals (3 species), and retreaters (10 species) on the basis of summed dominance ratio ($SDR_3$). Biological spectra showed the $H-D_1-R_5-e$ type in both the burned and unburned areas. The species of Lespedeza ($SDR_3$=94.7), Miscanthus (91.95), Festuca (68.33), and Spodiopogon (52.06) were dominant in the burned areas, while the species of Pinus (76.67), Robinia (56.25), Quercus (52.08), and Carex (40.25)were dominant in the unburned area. Dominance index (C) in burned and unburned areas was 0.15 and 0.25, respectively. the index of similarity (CCs) was 0.42. The degree of succession (DS) and species diversity (H) in burned and unburned areas were 675.8, 884.2 and 4.07, 2.05, respectively. The degree of succession in the burned area graduall increased and the burned area was recovered to be simmilar to the unburned area. Evenness index in burned and unburned areas was 0.965 and 0.595, respectively. |
