Abstract

To identify the flora of the vascular plant on Chujado Island in Chuja-myeon, Jeju-si, Jeju Province, Korea, eleven field surveys were conducted between April to September of 2013 and from May to September of 2018. The results of the surveys identified 558 taxa, with 97 families, 311 genera, 481 species, two subspecies, 65 varieties, and ten forms of vascular plants on Chujado Island. Of the 558 taxa identified, seven were endemic species and eight were rare plants according to the Korea Forest Service. Furthermore, 109 of the taxa identified were from floristic environments, while 62 were considered to be naturalized plants, with three of these considered to be invasive and causes of ecosystem disturbances. The highest degree of similarity among the plants from seven sites adjacent to Chujado Island was found on Saengil Island, at 51.7%.

본 연구는 제주도 제주시 추자면에 위치한 추자도의 관속식물상을 조사하기 위해 2013년 4월부터 동년 9월, 2018년 5월부터 동년 9월까지 총 11회에 걸쳐 현지조사를 수행하였다. 조사 결과 추자도의 관속식물은 총 97과 311속 481종 2아종 65변종 10품종의 558분류군이 조사되었다. 한반도 특산식물은 7분류군이며, 희귀식물은 8분류군이다. 식물구계학적등급종은 109분류군이었으며, 귀화식물은 62분류군으로 확인되었다. 추자도와 인접한 7개 지역과의 식물상 유사도는 생일도가 51.7%로 가장 높게 나타났다.
