Forty-three rectangular plots of 10×25 m^2 were surveyed for classifying the community types as well as the endangered and rare plant species at the Heng-Chun Natural Preserved Area, which is administrated by the Heng-Chun Branch Station of the Taiwan Forestry Research Institute. The gathered data were analyzed by using the TWINSPAN method. The results showed that five community types could be distinguished, namely, Acacia confusa type, Largestroemia subcostata-Fraxinus formosana type, Aglaia formosana-Pouteria obovata type, Aglaia formosana-Diospyros maritima type, and Diospyros maritime-Drypetes littoralis-Diospyros discolor type. The composition, structure, and natural regeneration of the dominant species of each community were discussed. Totally, 308 species belonging to 86 families and 244 genera were found in this area. Among the species, in terms of IUCN classification, two endangered, two vulnerable, and four rare species of this island were recognized.
