경상북도 봉화군에 위치한 각화산(1,177m)은 태백산맥에서 소백산맥으로 갈라지는 기점을 이루는 산으로 구령산, 청옥산, 옥석산 등과 함께 백두대간 일대의 중요한 산으로 인식된다. 특히 각화산은 조선왕조실록을 보관했던 태백산 사고지터(사적 제 348호)를 품고 있는 역사적인 장소이기도 하다. 본 연구는 각화산 일대 관속식물의 분포상을 파악하고자 2017년 5월부터 2018년 9월까지 진행되었다. 연구 결과 조사지 내 관속식물은 92과 291속 413종 4아종 38변종 6품종으로 총 461분류군이 확인되었다. 이는 경상북도 관속식물 1,684분류군(Korea National Arboretum, 2016)의 27.4%, 한반도 관속식물 4,499분류군(Korea National Arboretum, 2018; Http://www.nature.go.kr/kpni/)의 10.2%에 해당되는 것으로 분석되었다. 각화산 일대의 주요 식물 가운데 한국특산식물은 12분류군(할미밀망, 진범, 처녀치마, 지리대사초 등)이 확인되었고, 산림청 지정 희귀식물은 VU등급(꼬리진달래, 노랑무늬붓꽃) 2분류군, LC등급(너도바람꽃, 쥐방울덩굴, 도깨비부채) 3분류군으로 총 5분류군의 희귀식물이 분포하는 것으로 조사되었다. 또한, 식물구계학적 특정식물 IV등급 5분류군, III등급 13분류군, II등급 21분류군, I 등급 25분류군이 확인되었고, 외래식물은 총 24분류군으로 도시화지수(%) 6.8%, 귀화율은 5.2%에 해당되는 것으로 분석되었다. 조사된 식물의 유용성 분석 결과, 식용식물 348분류군(75.5%), 섬유용식물 1분류군(0.2%), 약용식물 기분류군(15.4%), 관상용식물 18분류군(3.9%), 목초용식물 102분류군(22.1%) 목재용식물 14분류군(3.0%) 등으로 확인되었다. 본 연구 결과물은 각화산의 식물 현황을 제시함과 동시에 생태축으로 연결된 백두대간 일대의 효율적인 관리 및 보전 방안을 마련하기 위한 기초자료로 활용 될 것이라 기대한다.

The distribution on 88 taxa of wild orchids in the Korean Peninsula was investigated by the examinations of specimens and the distribution maps were presented. The species numbers distributed at each eight floral regions in the Korean Peninsula are as the followings; Gapsan Province 27 taxa, Gwanbuk 21, Gwanseo 13, Middle 37, South 39, Southern-coast 33, Jeju 64 and Ulleung 19. Most species (72.7%) of Korean wild orchids are found in the Jeju Island. Eighteen taxa of them are restricted to the island in the Korean Peninsula. Among Korean species, 30 taxa grow at evergreen broad-leaved forests, and 16 are northern elements distributed at high mountains or northern part. In terms of distribution, the Korean wild orchid species are classified into IUCN Red List Categories by a modified criterion for Korean plants. No orchid species included EX or EW categories is found in the Korean Peninsula. Ten species are designated to be in CR category; Cymbidium kanran, C. lancifolium, C. ensifolium, Cypripedium japonicum, Cyrtosia septentrionalis, Dendrobium moniliforme, Habenaria chejuensis, H. radiata, Neofinetia falcata and Sedirea japonica, of which C. ensifolium and H. chejuensis are regarded as CR species for the first time. On the other hand, 22 taxa are classified into EN category, and the following nine taxa are newly proposed to be EN species; Gastrochilus japonicum, G. fuscopunctatus, Gastrodia verrucosa, Habenaria flagellifera, Herminium lanceum var. longicrure, Chamaegastrodia sikokiana, Lecanorchis kiusiana, Neottia hypocastanoptica and Tipularia japonica.

This study was carried out to investigate the flora of Oeumsan Mountain (Hongcheon-gun and Hoengseong-gun, Gangwon-do) from March of 2016 to September of 2017. The vascular plants were summarized into 509 taxa, including 98 families, 301 genera, 436 species, 4 subspecies, 57 varieties and 12 forms. Among the 509 investigated taxa, 9 Korean endemic, 1 endangered plant, 8 rare plants and 57 floristic regional indicator plants were also included. The naturalized plants encompassed 35 taxa. The percentage of naturalized plants species and the urbanization index were estimated to be 6.9% and 10.9%, respectively.

This study was carried out to investigate the vascular plants of the protected area for forest genetic resource conservation in the National Yonghyeon natural recreation forest. The vascular plants collected 7 times (from February to September 2014) were consist of total 460 taxa; 95 families, 280 genera, 398 species, 3 subspecies, 50 varieties and 9 forms respectively. The 6 taxa of Korean endemic plants and 8 taxa of Korean rare plants were investigated. The floristic regional indicator plants found in this area were 43 taxa comprising 7 taxa of grade IV, 7 taxa of grade III, 12 taxa of grade II, 17 taxa of grade I. The naturalized plants were 39 taxa, therefore naturalized ratio was 8.5%. 460 taxa listed consist of 189 taxa (41.1%) of edible plants, 155 taxa (33.7%)of medicinal plants, 177 taxa (38.5%) of pasture plants, 52 taxa (11.3%) of ornamental plants, 17 taxa (3.7%)of timber plants, 12 taxa (2.6%) of fiber plants and 3 taxa (0.7%) of industrial plants. The vegetation status of investigated area was comparatively well conserved, but human-induced damage is increasingly greater. Therefore, a long-term monitoring of vascular plants and vegetation movement must become accomplished.

Ten taxa of green algae collected at 8 stations of reservoirs and one of aerial habitat were reported newly in Korea. They belong to 7 genera, 2 species, 6 varieties and 2 forms and include one taxon of Scenedesmus, Actinotaenium, Euastrum, Hyalotheca, Staurastrum and Teilingia respectively, 4 taxa of Cosmarium. The Korean green algae, including these newly reported ones, totals to 1,131 taxa, and classified as 1 class, 10 orders, 34 families, 140 genera, 728 species, 318 varieties and 85 forms. Actinotaenium cucurbita var. cucurbita f. rotundatum cultured in this study was appeared to be variable in the size of isthmus. In the Korean taxa of Cosmarium lapponicum var. granulatum, C. portianum var. orthostichum and Euastrum denticulatum var. rectangulare, cell sizes were shown smaller than previously reported ones. Five taxa including Cosmarium lapponicum var. granulatum were occurred in the eutrophic states, and Cosmarium decedens, previously reported as present in the freshwater area, was collected at the aerial habitat in this study.

This study presents the flora of nonvascular plants (bryophytes) and vascular plants within the Wangpicheon Ecosystem and Landscape Conservation Area in Korea. The time of the survey was divided into four seasons. The fieldwork was conducted for a total of 18 days from November of 2016 to October of 2017. The land plants in the Wangpicheon conservation area were identified as 758 taxa with 164 families, 455 genera, 698 species, 10 subspecies, 47 varieties and 3 forms. Among them, bryophytes amounted to 122 taxa and vascular plants numbered 636 taxa. Native plant amounted to 693 taxa. In total, there are 113 floristic target species in Korea, including one level V taxon, in this case Swertia wilfordii; six level IV taxa; 31 level III taxa; 38 level II taxa; and 37 level I taxa. There are nine endemic plants, including Sillaphyton (=Peucedanum) podagraria, which is the endemic genus; two rare plants; fifteen northern plants; and one southern plant as target plants adaptable to climate change. Also, there are forty-six naturalized plants and five ecosystem-disturbance organisms. The results of this study suggest several species that should be preserved and can serve as basic information with which to establish conservation and management plans for the Wangpicheon conservation area.
