This study aimed to develop a conservation model for the rare and endemic plant Iris koreana Nakai by examining the community structure of its native habitats and analyzing ecological information, including environmental factors, to facilitate effective conservation and utilization. From March to August 2021, a total of 15 native habitats of I. koreana were surveyed, resulting in the identification of four vegetation units and seven community types. Importance value analysis indicated three distinct trends: succession driven by Quercus serrata (vegetation unit 1), stabilization communities dominated by Q. serrata and Fraxinus rhynchophylla (vegetation unit 2), and competitive communities among co-occurring species (vegetation units 3 and 4). Non-metric multidimensional scaling (NMS) analysis suggested that soil environmental factors exhibited significant correlations. Based on the survey findings, a conservation model was proposed that focuses on dominant species and key environmental variables across different stratifications. It is anticipated that the implementation of this conservation model for establishing ex-situ conservation sites will enhance ongoing monitoring of population dynamics and microenvironmental factors, thereby contributing to the formulation of effective strategies for species conservation.
