%X This study examined the distribution, population and vegetation structure of Corylopsis coreana inSouth Korea. C. coreana is distributed around the Suncheon area, Jeollanam-do, on the southern part of theKorean Peninsula, but the species is also found in Pocheon and Gangneung, on the central and central eastparts of the peninsula. This discontinuous pattern of distribution is coupled with the unusual feature of onlygrowing on northern exposed slopes. The mean density of C. coreana populations is 35 individuals per 100 m2,ranging up to a maximum of 92 individuals per 100 m2. Cut specimens sprouted a maximum of 38 stems perplant. Based on DCA analysis, the species' habitats was divided into three types by species composition andstratification structure. These types include: habitats affected strongly by human activities, valley and mantlecommunities which are affected relatively little by human activities, and stable forests. Populations affected byartificial intervention have actually flourished, while some populations in the stable forest system have declined.We conclude that the species, now endangered, should be maintained by means of specific external interventionssuch as cutting or removal of the canopy. To this end, further ecological data should be collected throughmonitoring and research to identify appropriate interventions to support threatened C. coreana populations.
