Vegetation types of the native conifer forests in the ridge of the Baekdudaegan, South Korea, were classified using the Braun-Blanquet method and TWINSPAN and its ecological characteristics analyzed with special repect to floristic composition. The vegetation type was classified into two types (Pinus densiflora-Carex humilis and Pinus koraiensis-Dryopteris crassirhizoma types) and seven groups. Mean species richness and total plot cover per unit area ($/100m^2$) were $21.9{\pm}8.9$ spp. and $146.9{\pm}32.3$%, respectively. The plant species composed of 82 families, 217 genera, and 387 species and the three major families, Compositae, Liliaceae, and Rosaceae, made up about 25.6% of the total species. The 7.8% of total families were the families with occurrence of only one species. The highest relative importance value was 19.2, the species belonged to Pinaceae and the pattern was different from species richness pattern of other families.
