We investigated the flora of vascular plants in Mt. Papyeong which is located in the northern part of Paju and the border of western DMZ through 13 surveys from April 2016 to August 2019. The vascular plants of Mt. Papyeong include 410 taxa; 361 species, 9 subspecies, 36 varieties, and 4 forms from 257 genera of 91 families. Among 410 taxa, we characterize endemic species, rare and endangered plants, floristic regional indicator plants, and climate change adapted plants in Korea. Specifically, there are 9 Korean endemic plants designated by Korea National Arboretum and 6 taxa by Korean Ministry of Environment. According to IUCN evaluation, there are 13 rare and endangered plants in Mt. Papyeong. On the other hand, 2 taxa were listed in a red list suggested by Korean Ministry of Environment. The floristic regional indicator plants include 46 taxa which are composed of 2 species of IV degree, 13 taxa of III degree, 11 taxa of II degree, and 20 taxa of I degree. Also, 27 naturalized plants were identified, and the percentage of Naturalized Index (NI) and Urbanization Index (UI) were 6.58%, and 8.43%, respectively. We hope that this investigation provide a valuable data for applying the further studies on the biodiversity and strategy of conservation of environment in the DMZ and Paju areas.

민속식물과 그 이용에 관한 전통지식이 산업화, 도시화 및 노인 세대의 퇴장과 더불어 빠르게 사라지고 있다. 이에 본 연구는 민속식물 주권확보 기반구축을 위하여 2005년부터 2017년까지 1차(2005~2013), 2차(2014~2017)에 걸쳐 남한 전역 및 함경북도 접경지역을 대상으로 각 지역에서 전통적으로 이용해왔으며 전승되어 온 민속식물 관련 전통지식을 발굴 및 수집하였다. 민속식물 중 약용으로 사용된 것은 121과 383속 583종 3아종 64변종 12품종으로 총 662분류군으로 확인되어 식용 다음으로 큰 비중을 차지하였다. 이는 한반도 전체 관속식물 4,881분류군의 약 13.6%에 해당하며, 총 115,236건의 조사된 전통지식 중 17.9%를 약용이 점유하여 식용(67.2%) 다음이며 용재용(4.9%), 유지용(2.5%), 관상용(1.3%) 등에 비하여 상당히 높게 나타났다. 662분류군 중 자생식물은 511분류군(77.2%)으로 나타났고, 생활형은 다년생 초본이 295분류군(44.6%)으로 낙엽성 목본(186분류군), 1년생 초본(78분류군) 등 타 생활형에 보다 높았다. 약용식물의 이용부위는 뿌리(34.1%)가 가장 많았고 그 다음으로 줄기(16.2%), 잎(15.4%), 열매(12.1%), 전초(12.1%), 수피(3.2%), 종자(2.4%), 꽃(1.9%) 등의 순으로 나타났다. 우리나라에서 이용빈도가 높은 상위 10개 분류군을 살펴보면 익모초, 쇠무릎, 인동덩굴, 느릅나무, 삽주, 엉겅퀴, 쑥, 질경이, 오갈피나무, 할미꽃 등의 순으로 조사되었다. 본 연구에서는 민속식물의 이용에 대한 중요도를 알아보기 위하여 특정식물 종의 이용을 언급한 정보보유자의 수(FC: Frequency of Citations), 이용범주의 수(NC: Number of use-Categories), 특정식물을 이용하는 수(UR: number of User Reports)를 활용하여 문화적 중요도(CI: Cultural Importance), 상대적 인용빈도(RFC: Relative Frequency of Citations), 상대적 중요도(RI: Relative Importance) 및 문화적 가치(CV: Cultural Value)를 산출하여 우리나라에서 중요한 민속식물을 정량적으로 확인, 비교하였고 각 분류군별 지수도 제시하였다.

Hwangmaesan Mt. (1,108 m) is rich in forest biodiversity and is a part of the Sobaek mountain range located in Hapcheon-gun, Gyeongsang-do in Korea. Unfortunately, the biodiversity and ecosystem integrity of Hwangmaesan Mt. have recently been threatened by heavy human disturbances. We conducted thirteen field surveys between March and October of 2019 to investigate the vascular flora in Hwangmaesan Mt. Through this extensive survey, we found 628 taxa consisting of 106 families, 349 genera, 554 species, 16 subspecies, 48 varieties, and 10 forma. Based on a comparative analysis between the present findings and former flora reports, our results showed an increase by 28 percent in the number of taxa observed. Of the 628 taxa, dicotyledons made up the largest group (477 taxa, 76.0%) followed by monocotyledons (120 taxa, 19.1%). Endemic plants consisted of 16 taxa, with rare plants designated by the Korea Forest Service numbering 14 taxa. Ten taxa were listed on the Red list by the Ministry of the Environment. The floristic target species designated by the Ministry of the Environment numbered 75 taxa, whereas there were 42 taxa of invasive plants.

한경 곶자왈 산림유전자원보호구역은 개가시나무와 백서향 등을 포함한 암괴지대의 상록활엽수림으로서 그 중요성이 인정되어 산림유전자원 생태보전지역으로 지정 관리되고 있다. 따라서 본 지역의 식물상을 조사하여 곶자왈의 분포식물을 파악하고자 실시하였다. 본 연구는 한라산 서쪽 곶자왈지역 중 곶자왈 산림유전자원 보호구역으로 지정된 지역을 2017년 6월부터 2017년 9월까지 20여 차례 현장조사를 통하여 표본을 수집하고 이를 기록 정리하였다. 조사지역의 식물은 총 83과 181속 236종 23변종 2품종 총 261종으로 조사결과 양치식물이 7과 18속 30종 2변종 32분류군, 나자식물이 1과 1속 2분류군, 피자식물은 74과 162속 204종 21변종 2품종 227분류군 이었다. 그 중 쌍자엽식물은 67과 139속 179종 16변종 1품종 196분류군이고, 단자엽식물이 7과 23속 25종 5변종 1품종 31분류군이었다. 조사에서 확인된 환경부 멸종위기야생식물은 개가시나무 1종 이었다. 식물 구계학적 특정식물로는 총 97분류군이 조사되었다. 등급별로는 V등급 검정개관중, 개가시나무로 2분류군, IV등급 백서향, 녹나무 등 12분류군, III등급 아왜나무, 호자나무 등 37분류군, II등급 올벚나무, 개산초 등 13분류군, I 등급 푸조나무, 자금우 등 33분류군으로 확인되었다. 한국의 적색목록 식물을 분석해보면 취약(VU)은 개가시나무, 섬다래 등 3분류군, 준위협(NT)은 백서향, 약난초로 2분류군, 관심대상종(LC)은 골고사리, 새우난초 등 9분류군, 미평가종(NE)은 빌레나무 1분류군으로 나타났다. 이 결과는 청수 저지 곶자왈 지역의 생태학적 자료로 제주도 내 곶자왈과 비교하였을 때 맹아가 발달한 종가시나무가 우점하는 지역으로 향후 상록수림 천이에 의해 상록수 아래에 자라는 식물로 낙엽활엽수가 대체될 것으로 추정되어 지속적인 조사가 요구된다.

To provide fundamental information to areas that lack data on the plant resources and the ecosystem, this study conducted a survey on the vascular plants in Mt. Jigisan in Hongseonggun. The vascular plants identified during the six-round field surveys were a total of 443 taxa: 96 families, 286 genera, 391 species, 7 subspecies, 40 varieties, 3 forms, and 2 hybrids. On floristic regional of Korea, Mt. Jigisan is deciduous broad-leaved and conifer-mixed forest which is south province of Korean peninsula. 4 taxa of Korean endemic plants such as Populus ${\times}$ tomentiglandulosa, Forsytsythia koreana, Forsytsythia ovate, and Iris rossii var. latifolia were collected. The vascular plants on the red list according to IUCN evaluation basis were found to be 6 taxa: Vulnerable (VU) species of Forsytsythia ovata, Least Conern (LC) species of Chionanthus retusus, Pseudoraphis ukishiba, and Cymbidium goeringii, and Not Evaluate (NE) species of Panax ginseng, and Fimbristylis verrucifera. The floristic regional indicator plants were found 27 taxa: 2 taxa of grade V, 3 taxa of grade IV, 6 taxa of grade III, 4 taxa of grade II, and 12 taxa of grade I. The specific distribution plants were found 27 taxa: 4 taxa of northern part of plants, 12 taxa of southern part of plants, 10 taxa of isolation distribution of plants, and 1 taxon of recently reported Viola betonicifolia var. albescens. The invasive alien plants were identified as 67 taxa. The naturalized index (NI) was 15.12%, and urbanization index (UI) was 20.9%, respectively.

This study was conducted to prepare basic data by analyzing the biological values and environmental factors of algific talus slope in order to respond to climate change due to the greenhouse effect, and to establish plans for forest biodiversity preserving and managing. Meteorological information was measured and the flora of vascular plants were investigated for six algific talus slope by seasonally from 2020 to 2021. As a result of the investigation, the temperature of all 6 algific talus slope was lower than that of the area where the algific talus slope was located in summer, and flora was 101 families, 350 genera, 621 species, 18 subspecies, 57 variants, 7 varieties, 703 taxa. In sum, it is judged that the algific talus slope has sufficient reasons and value to be preserved because it has excellent micrometeorological value from the cold wind blowing in summer and phytogeographical value in which various plants live in a small area. However, in spite of such an important area, the management of algific talus slope is insufficient, and the algific talus slope is damaged or the ecosystem of the algific talus slope is disturbed. Therefore, it is necessary to establish a systematic conservation and management plan by designating algific talus slope as a forest genetic resource reserve and OECM.
