This study was carried out as basic data for the conservation and management of plant diversity in the Gudeuljang paddy fields stone retaining wall of Cheongsan-island by identifying the characteristics of vascular plants targeting Gudeuljang paddy fields stone retaining wall in Cheongsan-island. The total vascular plants of the Gudeuljang paddy fields stone retaining wall in Cheongsan-island have been identified with a total of 184 taxa of 60 families, 142 genera, 170 species, 5 subspecies, 9 varieties. Rare plants were 1 taxa, Korea endemic plants were 2 taxa, floristic regional indicator plants were 28 taxa, rock vegetation was 20 taxa, and invasive alien plants were 25 taxa. Among them, Selliguea hastata (Thunb.) Fraser-Jenk., a rare plants, has been identified as a small number of individuals in the Gudeuljang paddy fields stone retaining wall in Buheung-ri and Cheonggye-ri, but it is necessary to conservation the habitat because there is a concern that the species and population will decrease due to damage and neglect of the Gudeuljang paddy fields stone retaining wall.

Based on the Korean endemic plants, 18 taxa were listed; Salix purpurea var, japonica, Asarum sieboldii var. mandshuricum for. misnadrum, Persicaria lapathifolia for. alba, Pseudostellaria sylvatica, Aconitum pseudolaeve var. erectum, Corydalis maculata, Corydazis albipetala, Corydalis grandicazyx, Cardamine amaraeiormis, Chrysosplenium barbatum, Filipendula glaberrima, Lespedeza x tomentella, Acanthopanax chiisanensis, Melampyrum setaceum var. nakaianum, Weigela subsessilis, Adenophora triphylla var. hirsute, Cirsium setidens, Saussurea pseudogracilis. Specific plant species by floral region were total 81 taxa (12.6%); Prunus yedoensis in class V, 13 taxa (Thuja orientalis, Cimicifuga heracleiiolia, Sedum middendorffianutn, Rhododendron micranthum, etc.) in class IV, 17 taxa (Equisetum palustre, Aceriphyllum rossii, Angelica gigas, Cirsium setidens, etc.) in class III, 15 taxa (Heloniopsis orientalis, Lychnis cognata, Saxifraga oblongifolia, Viola orientalis, etc.) in class II, 35 taxa (Hosta capitata, Cimicifuga simplex, Chrysosplenium flagelliferum, Campanula punctata, etc.) in class I.

This study was conducted to predict the distribution of rare·endemic plants (Sophora koreensis Nakai) in the border forests where wildfire damage occurred and to quantify the damage. For this purpose, we tried to derive more accurate results through forest area damage (NBR) according to the Burn severity of wildfires, damage by tree species type (Vegetation map), and MaxEnt model. For Burn severity analysis, satellite imagery (Landsat-8) was used to analyze Burn severity (ΔNBR2016-2015) and to derive the extent of damage. To prepare the Vegetation map, the land cover map prepared by the Ministry of Environment, the Vegetation map prepared by the Korea Forest Service, and the vegetation survey conducted by itself were conducted to prepare the clinical map before and after the forest fire. Lastly, for MaxEnt model analysis, the AUC value was derived by using the habitat coordinates of Sophora koreensis Nakai based on the related literature and self-report data. As a result of combining the Maxent model analysis data with the Burn severity data, it was confirmed that 45.9% of the 44,760 m² of habitat (predicted) area of Sophora koreensis Nakai in the wildfire damaged area or 20,552 m², was damaged.

제주는 면적에 비해 생물종다양성이 높은 지역으로 평가된다. 한반도 자생 관속식물은 4,500여종으로 이 중 50%에 달하는 2,200종이 제주에 분포하고 있으며 최근 30년간 80여종의 미기록 식물이 출현하였다. 이러한 특성은 선태식물과 산림버섯 분야에서도 유사하게 나타나는 것으로 지리적 위치, 기후적 조건, 한라산으로 인한 수직 식생 분포, 특이산림생태계로 인한 입지 환경의 다양성과 관련이 있다. 동시에 제주는 희귀 및 유용 산림생명자원의 보고이다. 제주에서 수집하여 종의 실체를 확인한 2,167종을 대상으로 희귀성과 유용성을 평가한 결과 제주고사리삼, 구상나무, 갯취 등의 희귀·특산 식물이 400종, 흑오미자, 제주백서향, 황칠나무 등의 유용식물이 781종에 달하였다. 또한 제주는 우리나라에서 기후변화에 가장 민감한 지역으로 동북아시아 기후변화의 요충지로 전망되고 있다. 한라산의 구상나무가 쇠퇴하는 등 이상 징후가 지속적으로 증가하고 있으며 동북아시아 아열대 최북한계지로서 한반도 생물지리의 징검다리 역할을 하기 때문이다. 따라서 나고야의정서 발효와 기후위기로 산림생명자원의 보존과 활용의 중요성이 더욱 강조되고 있는 현재의 시점에서 제주는 우선 연구 대상지라 해도 과언이 아니다. 이에 국립산림과학원 난대·아열대산림연구소는 절멸 위기에 처한 종의 보존과 유용 산림생명자원의 활용 기반 마련을 위해 수집 및 탐색-빅데이터 기반 구축-증식기술 개발-현지내·외보존원 조성 및 관리 기술 개발 등의 일련의 연구를 20년 이상 수행해 왔다. 여기에서는 제주지역 산림생명자원의 가치와 함께 보존과 활용 연구 성과를 소개하고 향후 연구 방향을 제안함으로써 산림 바이오 소재 산업화와 관련된 학계와 임업인 및 기업에 도움이 되고자 한다.

Present problems of the Korean rare and endangered plant species evaluations are discussed. It is proposed that the evaluation criteria for Korean rare and endangered are urgently needed in the future. The translation of new proposed criteria into Korean should be discussed in order to avoid confusion in the future. The draft of a new criteria system for rare and endangered plant species. prepared by the S. S. C. (Species Survival Commission) of I. U. C. N (International Union of Conservation of Nature) are introduced. The proposed draft for the criteria being developed by the S. S. C. of I. U. C. N. are Extinct, Extinct in the Wild, Critical, Endangered, Vulnerable, Susceptible, Safe /Low Risk, Insufficiently Known, and Not Evaluated. It is expected to take the more time to be technically developed further and also officially recognized by the I. U. C. N. for the practical use in the future.
