Abstract

Field surveys on the vascular flora of Gaeyado Island were carried out eight times between April and September 2024. In the study, a total of 386 taxa were recorded, including: 85 families, 273 genera, 351 species, seven subspecies, 27 varieties, and one forma. Among them, one endangered taxon was identified, Ranunculus kadzusensis Makino during the survey. Four Korean endemic plants were investigated, including Hemerocallis hakuunensis Nakai and Indigofera koreana Ohwi. A total of 48 taxa of floristic regional indicator plants were recorded, including one taxon of V, four taxa of IV, seven taxa of III, 10 taxa of II, and 26 taxa of I. Alien plants were recorded a total of 79 taxa with a Naturalization Index (NI) of 18.1% and an Urbanization Index (UI) of 23.6%. Among them, three ecosystem disturbance species were recorded such as Humulus japonicus Siebold & Zucc., Lactuca serriola L. and Sicyos angulatus L. Compared with previous floristic records for Gaeyado Island, the present study added 305 taxa as new records for the island, comprising 72 families, 223 genera, 276 species, 7 subspecies, 21 varieties, and one forma. These results provide essential baseline data for the conservation of native plant resources on Gaeyado Island, as well as for the efficient management and sustainable use of its plant resources.
