This study was conducted to investigate the habitat positional environment and vegetation properties of Mankyua chejuense. The habitats were classified into two types depending on the depth of the habitat, the ratio of rock exposure, the dominant species and the surrounding vegetation, which affected the vegetation of the habitats. The habitats with a high ratio of rock exposure showed a distinctive geographical boundary to the adjacent region and most of them were composed of trees that grow in humid environment. On the contrary, in the soil-rich habitats, the depth was shallow, soil layer was well developed, and the trees were introduced from the adjacent areas. However, the dominant species in the herbaceous layer were aquatic plants, which indicated that the habitats had the properties of wetland. Therefore, it was found that thes habitats of Mankyua chejuense have the properties similar to those of marshland. For the preservation of Mankyua chejuense, it is very important to make the habitats maintain such properties of wetland.
