  • The flora of the Odaesan National Park, located in the areas of Pyongchang-gun, Myongju-gun and Inje-gun, Kangwon-do was surveyed. Field works was undertaken five times between March to October, 1995. The total number of vascular plants in the Odaesan National Park was surveyed was 512 taxa; 87 families, 277 genera, 435 species, 68 varieties, 2 subspecies, and 7 forms. The vascular plants were classified as 459 taxa, 85 families, 255 genera, 389 species, 61 varieties, 2 subspecies and 7 forms in Odaesan, 309 taxa 73 families, 194 genera, 257 species, 45varieties, and 5 forms in Hwangbyongsan and 151 taxa, 60 families, 115 genera, 138 species, 12 varieties and 1 form in Sogumgang area. Also this study recorded 35 taxa of Korean rare and endangered plant species. Some of the habitats of rare and endangered plant species are located in the vicinity from the nature trails. Conservation measures, at both the habitat and species levels, are urgently needed to mitigate against destructive human activities, such as an illegal mass collecting and trampling.

  • Sonjook island is located Samsan-myeon, Yeosu-si, Jeollanam-do. All of field information was collected from January 2001 to November 2002. The vascular plants recorded as total 584 taxa, 5 forms, 60 varieties, 519 species, 365 geneta, 113 families. Sonjook islands shows the typical vegetations including the lower area of temperate region of Korean peninsula and evergreen broad-leaved forests, Pinus thunbergii forest. The Korean endemic plants were recorded as 13 taxa (5 variety, 8 species, 10 genera, 10 families), 4 taxa as rare and endangered plants (Psilotum nudum (L.) Griseb., Milletia japoniea A. Gray, Arisaema negishii Makino, Sarcanthus scolopendrifolius Makino). The naturalized plants were 23 taxa (20 genera, 9 families, 8.2% among the total naturalized plants in Korea. This area is ecologically important place that Korea endemic plant, rare and endangered plants ranges much than area. On the one hand, threat from degraded by environmental pollution that share of naturalized plant rises gradually augment. Strong conservation policy and development control should be considered.

  • The flora of vascular plants around Chunji and Sochunji in Mt. Baekdu was listed 120 taxa; 31 families, 81 genera, 97 species, 1 subspecies, 21 varieties and 1 form. About endangered wild plants, 2 taxa (Paeonia obovata, Rhododendron aureum) are in class II. 12 taxa were listed as rare and endangered plants; Disporum ovale, Lilium davuricum, Saxifraga punctata, Rosa marretii, Cnidium tachiroei, Bupleurum euphorbioides, Halenia corniculata, Gentiana jamesii, Pedicularis verticillata, etc. 10 taxa were listed as Korean endemic plants; Lilium amabile, Aconitum pseudolaeve var. erectum, Oxytropis anertii for. alba, Valeriana officinalis var. latifolia, Cardamine resedifolia var. morii, Homopteryx nakaiana, Saussurea alpicola, Ligularia jamesii, etc. Specific plants by floral region were total 47 taxa; 3 taxa (Paeonia obovata, Rhododendron aureum, Pedicularis verticillata) in class V, 15 taxa (Lycopodium annotinum, Alnus maximowiczii, Saxifraga punctata, Petasites saxatile, etc.) in class IV, 5 taxa (Spiraea salicifolia, Sanguisorba hakusanensis, Acer ukurunduense, Campanula glomerata var. dahurica, Cacalia adenostyloides) in class III, 18 taxa (Lycopodium chinense, Disporum ovale, Ceologlossum viride var. bracteatum, Betula ermani, Aruncus dioicus var. kamtschaticus, Filipendula multijuga, Geranium eriostemon, Cnidium tachiroei, Ligularia stenocephala, etc.) in class II, 6 taxa (Pinus koraiensis, Cimicifuga simplex, Sanguisorba tenuifolia var. alba, Senecio nemorensis, Cacalia hastata subsp. orientalis, Cirsium pendulum) in class I. Peculiar flora around Chunji is thought to be made by the environmental factors such as wind, temperature and rainfall that influence the plants' growth.

  • This study was carried out to investigate the flora of indigenous habitat of Simjeok forest wetland, Mt. Jeombomg forest wetland, Mt. Sohwangbyung forest wetland, Jilmoi-neup, and Mt. Myeon forest wetland in Gangwon Province. The vascular plants were summarized as 547 taxa; 92 families, 296 genera, 468 species, 4 subspecies, 67 varieties, 8 forms. The plants that are specially noteworthy are 17 taxa of Korean endemic plants, 3 taxa of Critical Endangered Species (CR), 4 taxa of Endangered Species (EN), 8 taxa of Vulnerable Species (VU) and 17 taxa of Least Concemed Species (LC) in rare plants as categorized by the Korean Forest Service. Furthermore, V, IV, III degrees of floristic regional indicator plants as categorized by the Korean Ministry of Environment included 9 taxa, 14 taxa and 34 taxa, respectively. In addition, 25 taxa of naturalized plants were observed. In this study, we identified a variety of plants observed in the wetlands of Gangwon Province. We believe that this study will provide useful data for future research on the conservation and management of wetlands.

  • This study aims to investigate the flora of Mt. Cheonma (Namyangju-si, Gyeonggi-do, Korea), including Korean endemic, rare and endangered plants. To support the biodiversity and usefulness of this investigation, we checked the red list plants, floristic regional indicator plants, climate change adaptation target plants and naturalized plants, and compared composition of plant species in Mt. Cheonma with nearby mountains. Totally, we performed 22 field investigations from April 2012 to October 2014. The number of vascular plants in this region is 433 taxa and comprised of 94 families, 266 genera, 378 species, 2 subspecies, 46 varieties, and 7 forms. Among them, there are 13 endemic plants designated by Korean Forest Service, whereas only 10 taxa are endemic species by Korean Ministry of Environment (KME). According to the IUCN criteria, there are 12 rare and endangered plants composed of 9 Least Concerned (LC), 2 Vulnerable species (VU), and one Endangered species (EN) found by Korea National Arboretum (KNA). Meanwhile, 8 taxa including 7 Least Concerned (LC) were found in Red List of KME. The floristic regional indicator plants designated by KME were 49 taxa. In addition, there are 14 taxa in The Adaptable to Climate Change Plant List designated by KNA, while only 19 taxa are naturalized plants. Generally, there are 190 common taxa in Gwangju Mountains area, and only 51 taxa are distributed in Mt. Cheonma.
