The purpose of this study was to investigate the location characteristics, soil environment and vegetation structure of habitats of Daphne pseudomezereum var. koreana. The relationship between each factor was analyzed to provide the basic data of ecosystem restoration in response to conservation of natural habitat and climate change. The rock exposure was 15 ~ 35%, which means that the average is 24%. The vascular plants of the entire native habitats of D. pseudomezereum were identified as 129 taxa consisting of 46 families and 95 genera. The results of the Two-way cluster analysis using PC-ORD were divided into three plant communities: cluster I (Tilia amurensis - Quercus mongolica), cluster II (Fraxinus rhynchophylla - Acer pseudosieboldianum), and cluster III (Ulmus davidiana var. japonica) species diversity index was highest in cluster I (1.124) and cluster Ⅱ was 1.047 and cluster Ⅲ was 0.932. The habitats of D. pseudomezereum are either loam or clay loam. Soil acidity, organic matter content and available phosphoric acid were found to be pH 5.40, 14.38% and 31.08ppm, respectively. As a result of ordination analysis of soil characteristics, community, and characteristic species, the most significant factors were magnesium content of soil, shrub layer and altitude.
