  • The vascular plants of Cheonbongsan(608m) and its adjacent regions, located in Boseong-gun, Jeollanam-do were surveyed from March to October 2005. The vascular plants collected 4 times were consisted of total 511 taxa; 104 families, 307 genera, 446 species, 3 subspecies, 56 varieties and 6 formas respectively. Among them, 12 taxa Korean endemic plants and 8 taxa of Korean rare plants were investigated in addition to 46 taxa of specially designated plants announced by the Ministry of Environment. The naturalized plants were 38 taxa, therefore naturalized ratio was 7.4%, higher than naturalized ratio average in Jeollanam-do.

  • 학술림은 학생, 교수, 산림 연구기관의 실험 실습 등의 연구 기능을 하는 숲이며, 경제적, 사회적 및 환경적으로 큰 의미가 있어, 학술연구 및 교육에 있어서 중요한 필수 자산이다. 국내에 분포하는 학술림의 전체면적은 약 34,941ha로 국내 전체 면적 6,335,000ha의 0.55%를 차지하고 있다. 국내 학술림을 행정적으로 남부, 중부 및 북부 세권역으로 나눠볼 수 있는데 중부권역에 속해있는 한 곳인 국민대학교 학술림의 자생식물을 조사하였다. 국민대학교 학술림이 위치한 경상북도 안동시 길안면 배방리 일대는 청송 유네스코 세계지질공원 및 주왕산국립공원과 인접함에도 불구하고 연구가 부족한 실정이다. 본 연구에서 확인된 관속식물은 97과 292속 518종 등 총 518분류군으로 조사되었으며, 산림청지정 희귀식물로는 댕댕이나무, 산분꽃나무, 시호, 솜양지꽃, 산마늘 등 10분류군이 확인되었고, 특산식물은 청괴불나무, 참배암차즈기, 고려엉겅퀴, 분취 등 9분류군이 확인되었다. 식물구계학적 특정식물은 I등급은 고려엉겅퀴, 백선, 뻐꾹채, 초롱꽃, 투구꽃 등 26분류군, II등급은 곰취, 구와취, 노랑제비꽃, 채고추나물, 호오리새 등 11분류군, III등급은 복자기, 시닥나무, 참조팝나무, 눈개승마, 다북떡쑥 등 24분류군, Ⅳ등급은 개아마, 뚝사초, 산마늘, 왜방풍, 참배암차즈기 등 8분류군, V등급은 산분꽃나무 1분류군으로 확인되었다.

  • The existence of endemism in many parts of the world is an important factor for conservationists. Conservation can only be carried out under national legislation, and national endemics, which have very limited ranges, fully depend on the effort and success of conservation. A total of 523 vascular plant taxa were listed in the latest national checklist by Ministry of Environment in 2005, while the 'Creation and Furtherance of Arboretums Act' including a national endemic list (appendix 4-1) was established by Korea Forest Service and was legislated as a law in late 2011. This legislation by Korea Forest Service on endemism of Korean vascular plants have required much attention because of discrepancies of nomenclature, taxonomic bias and inflation. Examining data for both lists proposed by Ministry of Environment and Korea Forest Service, of the total of 360 legislated taxa, around 286 taxa are shared with the list of Ministry of Environment, of which about 80% have been found as common taxa. Around 67(18.7%) are typographic errors, and 14 taxa (3.9%) are recorded as illegitimate and invalidly published names. Through this analysis 12 taxa (3.4%) were found in China as well as in Korea and these are thought to be non Korean endemic taxa. Taken together, the legislated list displayed 1/4 (24.9%) errors out of the total list. Only 59 taxa (16.5%) are identified as national endemic species. The remainder are either unresolved candidates (73 taxa, 20.4%) or synonyms (196 taxa, 54.7%) status. It must be noted, that the concept of endemism very much depends on the knowledge of the species concept, taxonomic bias and geographical range of a species. Also, the most major nomenclatural problem tend to be more stable if the information on database about Korea Plant Name, which is managed by Korea National Arboretum are well updated year to year. These exaggerated numbers underscore the urgency for regional conservation planning and implementing effective strategies to preserve these real endemic taxa into the future.

  • The flora of Ulleung island was summarized as 975 taxa with 122 families, 465 genus, 762 species, 5 sub-species, 178 varieties, 21 forms, and 9 hybrids. This extent of plant diversity of the island ecosystem was modified from the field surveys by the authors adding the number of 627 taxa; 109 families, 355 genus, 526 species, 2 sub-species, 89 varieties and 10 forms, and Considering the aspects of geographical distribution of the island, the flora showed much closer to the Korean penninsula than that of the Japanese Archipelago. An action plan including intensive conservation and management both for habitat and plant to conserve the island ecosystem should be prepared. The naturalized plants is expanding gradually due to the increase of the tourist. The Ulleung island ecosystem should be conserved as the Protected Area, which is enlarged habitat compared with the present legal conservation actions.

  • This study was carried out to describe the basic materials of the flora and vegetation for the conservation and management of the Dokdo ecosystem. The vegetation types were investigated by physionomy. 53 taxa of vascular plants were found, including 29 families, 48 genera, 49 species, 1subspecies, and 3 varieties. Among the investigated 53 taxa, it was recorded as follows: 2 Korean endemic plants included Sedum kamtschaticum var. takesimense M.Park and Campanula takesimana Nakai and 6 naturalized plants included Brassica juncea (L.) Czern., Sonchus oleraceus L., Bromus catharticus Vahl, Lepidium virginicumL., Chenopodium album L., and Ipomoea purpurea Roth. In particular, common morning glory (Ipomoea purpurea Roth) was reported for the first time in this survey of Dokdo. Based on physionomy, the main plant communities of Dokdo Island were Aster spathulifolius-Sedum oryzifolium community, Aster spathulifolius-Artemisia Japonica subsp. littoricola community, Fallopia sachalinensis-Cyrtomium falcatum community, Echinochloa crusgalli community, Echinochloa crusgalli var. oryzicola community. The debates have been continuing about a mis-identification of plants. To avoid this debate and manage naturalized and cultivated plants, taxonomist surveys and continual monitoring for the Island are required.

  • This study was conducted to investigate the vascular flora of Masan, located in Goseong-gun, Gangwon-do, and to comprehend the distribution of remarkable plants such as rare and Korea endemic plants and invasive alien plants. The survey was carried out the distribution of vascular plants 11 times per season from 2010 to 2018. A total of 619 taxa in 93 families, 328 genera, 529 species, 6 subspecies, 78 varieties and 6 forms were identified on mt. Masan. Among them, Korean endemic plants are 21 taxa including Saussurea diamantica Nakai and are plants designated by the Korea Forest Service are 20 taxa counting Saxifraga octopetala Nakai. Invasive alien plants were classified a total of 35 taxa inclusive of Trifolium pratense L. (WS), Aster pilosus Willd. (SS), Coreopsis lanceolata L. (SR), Rumex obtusifolius L. (SC) and Lindernia dubia (L.) Pennell (CS). The naturalization rate was 5% and the urbanization index was 10.0%, respectively. Although this study identified the diverse distribution of major plants such as rare and endemic plants around Masan, it was confirmed that invasive alien plants, which pose a great threat to forest biodiversity conservation and promotion, spread and distributed in a specific section Therefore, it is urgent to establish a conservation strategy and countermeasures.
