To propose basic information for natural resource management and conservation strategy of Schisandra nigra Maxim., its habitat environment and vegetation structure of forest communities growing the species was investigated. Fourteen plots (each plot size 400 m^2) were set up at the distributed area of Cheju island, southern part of Korea. S. nigra is the economic useful species that scatteringly grows at 850~920 m in the western part, at 660~710 m in the northern part and at 750~1,250 m in the southern part of Mt. Halla. The community of S. nigra in Mt. Halla is the mixed secondary forest of pine and broad leaved trees that are mainly composed of Pinus densiflora, Quercus serrata, Styrax japonica, Lindera erythrocarpa and Carpinus laxiflora. The density in a main distribution sector of S. nigra appears in the range of 3~39 individuals per each 20×20 m plot. The distribution patterns by Morisita's Index showed that S. nigra was distributed randomly in all of the stands. The association analysis showed that the following tree species were positively associated with S. nigra. In other words, the following trees were appeared to require the same ecological niche together with S. nigra: Lindera erythrocarpa, Cornus waltri, Acer mono, and Styrax japonica.
