The flora of Sorok Island was investigated 8 times from January 2001 to November 2002. The vascular plants recorded as total 604 taxa, 13 forms, 65 varieties, 1 subspecies, 524 species, 397 genera, 128 families. The rare and endangered plants were recorded 1 taxa (Millettia japonica (Sieb. et Zucc.) A. Gray), 12 taxa (3 variety, 9 species, 10 genera, 10 families) as Korean endemic plants. The naturalized plants were 26 taxa, 1 variety, 25 species, 21 genera, 12 families, 4.30% and 9.15％ among the total naturalized plants and Urbanization Index in Korea. Visitor's numbers are expected to increase rapidly because nature views of Sorok Island are beautiful, which kind and number of naturalized plants are forecasted to be increased. Strong conservation policies should be considered.

The purpose of this study was to identify the ecological characteristics of Namhan Mountain Fortress Walls vascular plants through investigation and analysis of Namhan Mountain Fortress Walls and to provide basic data when establishing a plan for conservation and management of Namhansanseong Fortress Wall vascular plants. The result of this survey revealed 249 taxa composed of 77 families, 169 genera, 222 species, 5 subspecies, 19 varieties and 3 forms. In terms of life form of Namhan Mountain Fortress Walls, the appearance rate of Hemicryptophytes(H) was high. Rare plants was 1 taxa and Korea endemic plants was 5 taxa. The total number of floristic regional indicator plants was 15 taxa, gradeI 9 taxa, gradeII 2 taxa, gradeIII 3 taxa, gradeIV 1 taxa. Among them, Polygala tatarinowii Regel is considered to the most important(gradeIV), and it is first description because in Gyeonggi-do, as no additional forms have been confirmed other than this site. Plants identified as rock vegetation were found in 21 taxa. Invasive alien plants were identified 20 taxa. Plants distributed on the walls of Namhan Mountain Fortress, such as Aconitum longecassidatum Nakai, Clematis heracleifolia DC. var. tubulosa (Turcz.) Kuntze, Hylotelephium spectabile (Boreau) H.Ohba and Polygala tatarinowii Regel etc, are feared to decrease the number of species and individuals due to the loss of walls, the spread of invasive alien plant and human interference, so conservation and management measures are needed.

This study aimed to understand current flora of Western Civilian Control Zone (CCZ) in Korea. Some areas that located at Paju-si and Yeoncheon-gun were selected as representative survey area (Jangdan-myeon, Deokjin mountain fortress, Ilwol peak of Mt. Seokbyeong, Imjinriver, Sunaecheon stream, Sewolcheon stream in Paju and Banjeong-ri in Yeoncheon). Through this survey, 461 vascular plant specimens were collected from April 2012 to September 2014, twice a month and from October 2014 to October 2018, once a month. These were finally classified into 96 families 305 genera 413 species 4 subspecies 41 varieties 6 forms totally 464 taxa. There are remarkable plants such as 6 taxa of Korean endemic species, 44 taxa of specified species on a floristics aspect, and 35 taxa of alien and naturalized plants (7.5%). Meanwhile, it has not been observed any endangered plant species during the activities in this area.

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.

본 연구는 대구광역시 남구 대명동 앞산공원 일대 관속식물을 연구하기 위해 수행되었다. 2018년 4월 13일부터 2019년 9월 17일까지 총 38회에 걸쳐 조사를 수행하였고, 확인한 관속식물은 109과 338속 523종 65변종 10품종 5아종 5교잡종 3재배품종을 포함하여 총 611분류군을 확인하였다. 이 중 산림청 국립수목원 지정 희귀식물은 28분류군(멸종위기종(CR) 왕벚나무(식재), 위기종(EN) 깽깽이풀 등 4분류군, 취약종(VU) 멱쇠채 등 8분류군, 약관심종(LC) 측백나무 등 11분류군 및 자료부족종(DD) 김의털아재비 등 4분류군), 국립수목원 지정 특산식물은 좀비비추, 노랑갈퀴, 산앵도나무 등 12분류군, 식물구계학적 특정식물은 67분류군(V등급 깽깽이풀과 왕벚나무 2분류군, IV등근 비술나무 등 4분류군, III등급 음양고비 등 16분류군, II등급 큰참나물 등 3분류군, I등급 거미고사리 등 42분류군), 귀화식물은 오리새 등 42분류군을 확인하였다. 도시화지수 및 귀화율은 각각 13.08%, 6.89%로 나타났으며 이는 우리나라 평균 귀화율보다 다소 낮은 수치이다. 선행연구와의 목록 비교 결과 210분류군을 추가적으로 확인하였다. 이는 약 30년간 연구대상지의 선행연구가 이루어지지 않았다는 점과 그간 식물의 오동정, 다양한 식물의 유입 및 사람들의 왕래가 잦아짐에 따른 귀화식물의 유입 등 다양한 요인으로 판단된다. 아울러 1,000만명 이상이 이용하는 앞산공원 일대 주요 희귀식물의 서식처를 보호할 수 있는 방안이 필요할 것으로 판단된다.

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.

The flora in the region of Songnisan National Park ($N36^{\circ}28^{\prime}05^{{\prime}{\prime}}{\sim}36^{\circ}46^{\prime}38^{{\prime}{\prime}}$, $E\;127^{\circ}47^{\prime}06^{{\prime}{\prime}}{\sim}127^{\circ}57^{\prime}50^{{\prime}{\prime}}$) was surveyed from April 2000 to July 2006. Vascular plants in 26 collections included a total of 723 taxa: 115 families, 392 genera, 629 species, 4 subspecies, 72 varieties and 18 forms. Ninety-three of these taxa were first records for the region. In the flora of Songnisan National Park, 27 taxa were Korean endemic plants, 19 taxa were rare and endangered plants as designated by the Korea Forest Service. Forty-five of the taxa were with the levels III, IV, V in the floristic regional indicator plants which was designated by Korean Ministry of Environment, and 29 taxa were alien plants now naturalized in Korea. Owing to their unusual phytogeography and low number of populations, the taxa Crypsinus hastatus (Thunb.) Copel., Paeonia japonica (Makino) Miyabe & Takeda, Jeffersonia dubia (Maxim.) Benth. & Hook.f. ex Baker & S.Moore, Bupleurum euphorbioides Nakai, Phacellanthus tubiflorus Siebold & Zucc., Lilium cernuum Kom., Gastrodia elata Blume and Cephalanthera erecta var. subaphylla (Miyabe & Kud ) Ohwi were considered the most important. Based on these results, it is clear that appropriate plans to conserve the natural habitat of Songnisan National Park must be made immediately.
