Abstract

This study aimed to investigate the vascular flora of Buyongbong mountain (376 m), located in Yeongyang-gun, Gyeongsangbuk-do. A total of 13 field surveys were conducted between March 2019 and October 2024. Based on the collected specimens, 508 taxa of vascular plants were identified, comprising 111 families, 326 genera, 460 species, 11 subspecies, 36 varieties, and one forma. Among them, nine taxa were endemic to the Korean Peninsula. Fourteen taxa were listed in the regional red list, including two Near Threatened (NT) taxa and twelve Least Concern (LC) taxa. Floristic target plants amounted to 71 taxa, consisting of two taxa of grade V, 11 taxa of grade IV, 12 taxa of grade III, 16 taxa of grade II, and 30 taxa of grade I. Forty-nine taxa of alien plants were identified, with a naturalized index of 9.6% and an urbanization index of 12.5%. Five taxa of ecosystem-disturbing plants were also observed. In addition, the floristic similarity between Buyongbong mountain and the adjacent sedimentary-rock of Jaamsan mountain was evaluated using the Sørensen similarity index (CCs). Based on 364 taxa shared by both mountains, the similarity index was calculated as 70.1%. These results provide fundamental data for understanding plant diversity and conservation value of sedimentary-rock mountains and for establishing standardized surveys and long-term monitoring strategies in the future.
