Abstract

Floristic surveys were conducted from April to October 2024 in the Seolheulsan-Eungbongsan Mt. area of Namhaedo Island, Korea. A total of 446 vascular plant taxa were identified (111 families, 297 genera, 403 species, 7 subspecies, 34 varieties, and 2 forms), representing 9.5% of the Korean Peninsula flora. Nine taxa endemic to Korea and six red-listed taxa were recorded. Phytogeographically significant taxa totaled 78 (17.5%). Fifty-seven alien taxa were found, with a naturalization rate of 10.8% and an urbanization index of 16.2%. Field observations also indicated that Pueraria lobata (Willd.) Ohwi extensively dominated lower ridge zones and slopes adjacent to coastal areas; in repeatedly disturbed habitats, its vine cover may affect understory vegetation, suggesting the need for management based on long-term monitoring. Twenty-three climate change indicator taxa were identified, accounting for 56.1% of the nationally designated vascular-plant indicator taxa. These results provide baseline floristic data for southwestern Namhae Island and support long-term assessment of floristic change driven by disturbance and climate warming.
