Abstract

This study was conducted to investigate the flora of Sonjukdo Island(Yeosu-si), Korea. From results of four field surveys from April 2023 to October 2023, we identified 483 total taxa, representing 440 species, seven subspecies, 35 varieties, and one hybrid. They were placed in 322 genera and 109 families, including 249 taxa newly recorded in this study. Among them, four taxa were endemic to Korea, four taxa were IUCN red list plants, and 22 taxa were climate sensitive indicator plants. Floristic target plants amounted to 99 taxa, including two taxa of grade IV, 41 taxa of grade III, 10 taxa of grade II, and 46 taxa of grade I. A total of 54 taxa of alien plants were identified, with a Naturalized Index of 11.2% and an Urbanization Index of 13.8%. Three plants disturbed the ecosystem. The flora of this surveyed area belongs to the south-coast province among floral provinces of the Korean Peninsula. Our results provide basic data on vascular plants flora, plant species diversity, and distributional changes.

본 연구는 손죽도의 관속식물을 밝히고 주요 식물을 조사하였다. 2023년 4월부터 2023년 10월까지 총 4회에 걸쳐 조사한 결과, 관속식물은 109과 322속 440종 7아종 35변종 1교잡종의 총 483분류군이 확인되었으며, 이 가운데 249분류군은 본 조사에서 새롭게 기록되었다. 한반도 고유종은 4분류군, 지역적색목록은 4분류군, 기후변화 지표식물은 22분류군, 식물구계학적 특정식물은 총 99분류군으로 IV등급에 2분류군, III등급에 41분류군, II등급에 10분류군, I등급에 46분류군이 확인되었다. 외래식물은 54분류군이며, 귀화율 11.2%, 도시화지수 13.8%로 나타났다. 생태계교란식물은 3분류군이 확인되었다. 조사지의 식물상은 한반도 식물구계의 남해안아구에 속한다. 본 연구는 관속식물의 분포 자료로써 식물 종 다양성 및 분포변화의 정보로 활용될 것으로 생각된다.
