We investigated the flora of Mt. Namdeogyu, southern regions of Deogyusan National Park, from April of 2011 to September of 2012. The number of vascular plants in this area were summarized as 507 taxa, including 102 families, 296 genera, 444 species, 8 subspecies, 49 varieties, 6 forms. Among the recorded taxa, Korean endemic plants were 9 species and the floristic regional indicator plants were 80 taxa including 3 taxa in grade V, 3 taxa in grade IV, 19 taxa in grade III category. The rare and endangered plants which was designated by Korea Forest Service were 15 taxa comprising 1 endangered species (EN) of Rhododendron tschonoskii, 5 taxa of vulnerable (VU) such as Cynanchum inamoenum, Lilium cernuum, Gastrodia elata, Bupleurum euphorbioides, Paeonia japonica, and 9 least concerned (LC). In addition, the subalpine plants of the region were summarized as 24 taxa, and Mt. Deogyu area inclunding the Mt. Namdeogyu was suggested as the north most limits line of the distribution for 2 taxa, Abies koreana and Rhododendron tschonoskii, and as the south most limit of the distribution for Bupleurum euphorbioides.

The vegetation of Mt. Joghesan of a provincial park in Cheolanamdo was surveyed over twenty times from July, 1980 to December, 1981. The plants of Mt. Jonghesan consisted of 10 forma, 107 varieties, 597 species, 424 genera and 122 families, and among them were 204 species of esculent plants, 199 species of medicina plants and 30 species of the others oil plants and fiber plants. Evergreen herbs consisted of 12 species, including Coniogramme intermedia, Asplenium sarelii, and Asplenium incisum etc. And Evergreen broad-leaved trees consisted of 22 species, including Thea sinensis, Sasa borealis, and Quercus acuta etc. And evergreen needle-leaved trees consisted of 15 species, including Torreya nacitora, Pinus densiflora, Sciadopitys japonica, and Chamaecyparis obtusa etc. The community of broad-leaved consisted of Quercus spp, Carpinus laxiflora, Sasa borealis, including leading dominant species of Lespedeza maximowiczii, Viburnum erosum, Fraxius rhynchophylla, Viburnum dilatum, Rhus trichocarpa, Zelkova serrata, Miscanthus sinensis, Eragrostis ferrugina, Carex augustinowiczii persicaria filiforme var. neofiliforme, Vicia amoena, Smilax riparia var. ussuriensis, and Aster yomena etc. The vegetation of Seunamsa areas in Mt. Joghesan was favorable but the vegetations of the other areas in the mountain were negligible. The vegetation of Koolmokchi areas which had been much destroyed by forest fires was mostly covered with Quercus spp which are resistant to forest fires. Lindera sericea, Alangium platanifolium var. macrophyllum, Ilex macropoda, Corylopsis coreana, Albizzia julibrssin of old trees, Acer mono, the community of Thea sinensis, Stewartca koreana, Cornus alba, Dryopteris bisstiana, Asplenium incisum, Camptosorus, Lepisorus thunbergianus, gastrodia elata, Cymbidium goeringii, and the community of Persicaria filiforme var. neofiliforme etc. in Mt. Jonhesan are autochthonous flora, and their preservation is required. As the Pinus densiflora forest in Mt. Joghesan which was hewn down by human power has not been restored, Jeopchi areas and Koolmokchi areas in Mt. Joghesan have no Pinnus densiflora trees 700m above the sea level.

The flora in the region of Mt. Sobaeksan National Park ($N36^{\circ}50^{\prime}-37^{\circ}50^{\prime}$, $E128^{\circ}20^{\prime}-128^{\circ}43^{\prime}$) was surveyed from April of 2005 to October of 2011. The vascular plants from 27 field surveys were revealed to total 869 taxa, comprising 112 families, 429 genera, 756 species, four subspecies, 91 varieties and 18 forms. Sixty-eight taxa were the first records from this region. This field study discovered significant plants in various categories. Korean endemic plants numbered 25 taxa, and 18 taxa designated by the Korean Forest Service as rare plants were investigated in this region. The taxa in category II of rare and endangered plants and higher than the third degree among the floristic regional indicator plants designated by the Korean Ministry of the Environment were three taxa and 75 taxa, respectively. From a geographical perspective, limited distribution of Saxifraga octopetala, Corydalis grandicalyx, Aegopodium alpestre, and Polygonatum acuminatifolium at a latitude higher than that of Sobaeksan National Park suggest that Sobaeksan National Park might be the limit line of the distribution of the taxa. Stewartia koreana demonstrate a reversed pattern from the taxa above, occurring at a latitude lower than that of Sobaeksan National Park. In addition, naturalized plants of 53 taxa were recorded.

Gwangchiryeong, located adjacent to the Korean DMZ, is a mountain pass connecting Yang-Gu, Gangwon-do with In-je. It reaches a height of 800m (2,624ft) and stands on the flank of Mt. Daeam-san, which has an elevation of 1,304m (4,278ft). It is important to survey the flora of Gwangchiryeong in that not only the area encompassing the waterfall and the valley along with dense old-growth forest has various plant species but also it is a way to make out what kind of plant species exist in the DMZ due to the geographical characteristics of Gwangchiryeong adjacent to the Korean DMZ. Therefore, this study was conducted to elucidate the distribution of vascular plants and their value in Gwangchiryeong. The vascular plants that were collected 9 times from April 2014 to September 2015, and consisted of a total of 513 taxa: 88 families, 297 genera, 441 species, 4 subspecies, 62 varieties and 6 forms. Among those observed species, the rare plant species designated by Korea Forest Service were 22 taxa including Hanabusaya asiatica, Paeonia japonica, Saxifraga octopetala, etc. Endemic species were 22 taxa containing Cirsium setidens, Heloniopsis koreana, Salvia chanryoenica, etc. 18 taxa were recorded as naturalized plants and their naturalized rate and urban index were noted as 3.5% and 5.6%. Among the surveyed 513 taxa, edible, medicinal, pasturing, ornamental, timber, dye, fiber and industrial plants were 197 taxa, 154 taxa, 180 taxa, 49 taxa, 24 taxa, 8 taxa, 4 taxa and 3 taxa, respectively.

The current status of geographical distribution range of Deutzia paniculata, one of the korean endemic plants, was investigated based on the species distribution information. The information of the geographical range used for analysis includes all the published references to the distribution of D. paniculata, herbarium specimens in Korea National Arboretum (KH) including its online database: http://www.nature.go.kr, and field research. Although, D. paniculata was firstly recorded in Wonsan, Hamgyeongnam-do, North Korea, this research revelaved that D. paniculata is mainly distributed in Gyeongsangbuk-do and Gyeongsangnam-do, southern regions of the Korean Peninsula. According to the distribution map, this species was estimated on distribution edge of in Anyang region of Gyeonggi-do, Mt. Naejang of Jeollabuk-do and Mt. Taebaek of Gwangwon-do on the distribution edge. However, it was made use of intensive field survey to identify the natural population of the species in these regions. D. paniculata habitat was mainly distributed between 290 meters and 491 meters in altitude, but it was also found ranged from 936 to 959 meters in Gun-wi, Gyeongsangbuk-do, South Korea. The distribution slope was 5° to 35° and the north, N, NE and NW in the aspect. The flora of vascular plants in D. paniculata habitats was listed in 137 taxa: 54 families, 103 genera, 120 species, 2 subspecies, 12 varieties and 3 forms while Korean endemic plants were found in three taxa, Stewartia koreana, Weigela subsessilis and D. Paniculata. Based on a collection of non-biological environment and biological environment data, D. paniculata population were discussed to make strategy and basic research methods for sustainable preservation.
