This study is aimed at identifying the distribution of vascular plants growing at Mt. Dosolsan in Yanggu-gun, Gangwon-do. Field surveys were conducted for each season from March 2014 to November 2016. The flora of study area is found to consist of 516 taxa, 91 families, 296 genus, 455 species, four subspecies, 50 varieties, and seven forma. Rare plants were found to be of 31 taxa. Among them, rare plant species consisted of critically endangered species (CR degree): 2 (Lilium dauricum Ker Gawl., Cypripedium macranthos Sw.), endangered species (EN degree): 5 (Loranthus tanakae Franch. & Sav. etc.), vulnerable species (VU degree): 7 (Dryopteris laeta (Kom.) C.Chr. etc.), and least concerned (LC degree): 17 (Botrychium virginianum (L.) Sw. etc.). In all the surveyed areas, a total of 20 taxa (Pseudostellaria setulosa Ohwi etc.) were found to be endemic to Korea. The floristic special plants found in the surveyed areas were two taxa of grade V, 24 taxa of grade IV, and 31 taxa of grade III. The naturalized plants were identified as 15 taxa and included Chenopodium album L., Lotus corniculatus L., Robinia pseudoacacia L. etc.

The genetic relationships among five genera, seven species of Theaceae were examined through a random amplified polymorphic DNA (RAPD) analysis and internal transcribed spacer (ITS). In RAPD analysis, five of 15 arbitrary primers showed polymorphic bands, which were able to classify different genera and species of Theaceae. The genetic variations of Theaceae were from 0.031 to 0.484. In ITS analysis, the ITS sequences were analyzed using BLAST and showed high identities with sequences of Theaceae, seven species published in NCBI GenBank database, which ranged from 98 to 100%. Sequence alignment of seven species showed 34.9% identities for ITS 1 region and 43.7% for ITS 2 region. Pairwise sequence divergences among seven species ranged from 0 to 0.330%. In phylogenetic tree, they were divided into three groups. In conclusion, the molecular data generated in the present investigation will help to understand the genetic relationships of Theaceae and also might be useful for further studies in intra-species, inter-species, and molecular evolution researches.

This study was carried out to present the habitat distribution status and the habitat distribution prediction of Sophora koreensis, which is the Korean Endemic Plant included in the EN (Endangered) class of the IUCN Red List. The habit distribution survey of Sophora koreensis confirmed 19 habitats in Gangwon Province, including 13 habitats in Yanggu-gun, 3 habitats in Inje-gun, 2 habitats in Chuncheon-si, and 1 habitat in Hongcheon-gun. The northernmost habitat of Sophora koreensis in Korea was in Imdang-ri, Yanggu-gun; the easternmost habitat in Hangye-ri, Inje-gun; the westernmost habitat in Jinae-ri, Chuncheon-si; and the southernmost habitat in Sungdong-ri, Hongcheon-gun. The altitude of the Sophora koreensis habitats ranged from 169 to 711 m, with an average altitude of 375m. The area of the habitats was 8,000-734,000 ㎡, with an average area of 202,789 ㎡. Most habitats were the managed forests, such as thinning and pruning forests. The MaxEnt program analysis for the potential habitat of Sophora koreensis showed the AUC value of 0.9762. The predictive habitat distribution was Yanggu-gun, Inje-gun, Hwacheon-gun, and Chuncheon-si in Gangwon Province. The variables that influence the prediction of the habitat distribution were the annual precipitation, soil carbon content, and maximum monthly temperature. This study confirmed that habitats of Sophora koreensis were mostly found in the ridge area with rich light intensity. They can be used as basic data for the designation of protected areas of Sophora koreensis habitat. 본 연구는 한국 특산식물이고, IUCN Red List의 EN(위기종) 등급에 속하는 개느삼을 대상으로 자생지 분포, 자생지분포 예측을 하기 위해 수행되었다. 개느삼의 자생지 분포 조사 결과 ,강원도 양구군 13곳, 인제군 3곳, 춘천시 2곳, 홍천군1곳 총 19곳에 분포하는 것을 확인하였다. 우리나라에서 가장 북쪽 자생지는 양구군 임당리, 동쪽 인제군 한계리, 서쪽춘천시 지내리, 남쪽 홍천군 성동리로 각각 확인되었다. 개느삼 자생지의 해발고도는 169-711m에 분포하는 것으로 나타났고, 평균 해발고도는 375m로 조사되었다. 개느삼 자생지의 면적은 8,000-734,000㎡인 것으로 분석되었고, 평균 202,789㎡로조사되었다. 대부분의 개느삼 자생지는 간벌, 가지치기 등과 같은 숲가꾸기가 이루어진 곳으로 조사되었다. 개느삼 잠재분포지 분석을 MaxEnt 프로그램을 이용하여 수행한 결과, AUC값은 0.9762로 분석되었다. 분포예측 자생지는 강원도 양구군, 인제군, 춘천시, 화천군 지역에 집중되어 분포하는 것으로 나타났다. 자생지 분포예측에 가장 영향을 많이 미치는 변수는연간강수량, 토양탄소함유량, 최한월 기온으로 분석되었다. 본 연구 결과를 토대로 개느삼은 광량이 풍부하고 능선부에 주로서식하는 것을 확인하였고, 향후 본 연구결과의 자생지 정보를 토대로 개느삼 자생지를 보전하기 위한 보호지역 지정 등을위한 기초자료로 활용될 수 있을 것으로 판단된다.
DMZ 접경지역 인근 대득봉(철원군, 강원도) 일대의 식물상
안종빈,신현탁,정수영,윤정원,허태임,이준우,김상준 한국환경생태학회 2018 한국환경생태학회지 Vol.32 No.4
본 연구에서는 철원군 대득봉의 관속식물을 조사하기 위해 수행되었다. 비무장지대에 인접한 대득봉의 지리적 입지 는 DMZ와 그 이남지대를 연결하는 완충지대로 기능하고 있기에 대득봉의 식물자원을 조사하는 것은 DMZ의 식물상을 이해하는 한 방법이기도 하다는 점에서 본 연구는 중요한 의미를 지닌다. 대상지역을 2015년 5월부터 2017년 5월까지 총 7차례에 걸쳐 조사한 결과 관속식물은 84과 245속 341종 4아종 43변종 5품종으로 총 393분류군이 조사되었다. 그 중 산림청 지정 희귀식물은 삼지구엽초, 땅나리, 천마 등 총 8분류군, 특산식물은 처녀치마, 진범, 외대으아리 등 총 6분류군이 확인되었으며 식물구계학적 특정식물은 44분류군이 조사되었다. 귀화식물은 23분류군으로 확인되었으며 귀화율과 도시화지수는 각각 5.8%, 7.1%로 나타났다. The purpose of this study was to investigate the distribution of vascular plants in Mt. Daedeukbong. The study is significant because surveying the flora of old-growth forest in Mt. Daedeukbong is a way of understanding what kind of plant species exist in DMZ as the geographical characteristics of Mt. Daedeukbong adjacent to Korean DMZ have the role of a buffer zone connecting the DMZ and its southern region. We collected the vascular plants 7 times from May 2015 to May 2017 and found a total of 393 taxa consisting of 84 families, 245 genera, 341 species, 4 subspecies, 43 varieties and 5 forms. The observed rare plant species as designated by Korea Forest Service were 8 taxa, and the endemic species were 6 taxa. 44 taxa were listed as specific plant species based on phytogeographical in the investigated area. 23 taxa were recorded as naturalized plants, and the naturalized rate and urban index were 5.3% and 8.7%, respectively.
