The Zelkova genus is globally recognized as being predominantly endangered, emphasizing its high conservation value. And, Zelkova serrata, a native species in Korea, has been classified as Near Threatened(NT) in worldwide. The purpose of this study was to analyze the vegetation classification, species composition, and to investigate the characteristics of native habitat with the 125 vegetation data in Z.serrata forest. Based on species composition, the vegetation was categorized into 4 vegetation units and 7 species group types. The hierarchy of the Z.serrata community group was represented by the Lindera erythrocarpa community (subdivided Pinus densiflora group and Carpinus tschonoskii group) and Neolitsea sericea community. Successional tendency of Z.serrata forest based on the importance of each layer is predicted to be total of three types such as to maintain the stand, to success the Acer pictum var. mono forest, and to success Neolitsea sericea–Carpinus turczaninovii forest. Therefore, for the systematic preservation of zelkova trees, a management plan for each type of transition should be prepared.
