This study was aimed to design core areas applied by the global conservation criteria to promote the public awareness to the protected areas and the value cognition of the Key Biodiversity Areas (KBAs), targeting the Mt Seorak, according to the designation of globally important biodiversity areas. As a method for carrying out this study, the biota were cataloged through literature reviews and field trips. With applied by the Global Red List criteria of the International Union for Conservation of Nature (IUCN), only nine species were categorized in the studied area; plants were classified into six species as follows: Megaleranthis saniculifolia ohwi, Bupleurum euphorbioides Nakai, Hanabusaya asiatica Nakai, Thuja koraiensis Nakai, Leontopodium leiolepis Nakai, Androsace cortusaefolia Nakai, fish was classified one species as follow: Pungitius sinensis Tanaka, and the mammal was classified as two species as follows: Hydropotes inermis, Naemorhedus caudatus. According to the occupation area (EoO, Extent of Occurrence) and Minimum Viable Population(MVP), the size of protected area was 234.56㎢ for plants, 235.07㎢ for mammals, and 0.14㎢ for fish, and the Key Biodiversity Area (KBA) of Mt. Seolak suggested as 286.72㎢.

The vascular plants of Mt. Deog-yu area in the Baekdudaegan were recorded as 411 taxa; 91 families, 243 genera, 353 species, 53 varieties and 5 forma. From the floristic point of view, the Baekdudaegan, a main mountain range of the Korean peninsula, in the region of Mt. Deog-yu, belongs to the southern province in Korea, as the species like Cephalotaxus koreana, Lindera obtusiloba, Ilex macropoda and Stewartia koreana. are ranged in this region. But the species of the Northern element such as Betula costata, Betula ermani, Heloniopsis orientalis and Disporum ovale are also recorded in the region. Above the sea level from 1,000m, many sub alpine plant species are recorded. Rare and endangered plant species which are categorized by the Office of Forestry were 10 species such as Lilium cernum, Paeonia obovata, Abies koreana, Disporum ovale, Lilium distichum, Tricyrtis dilatata, Clematis chiisanensis, Bupleurum euphorbioides, Rhododendron schonoskii and Iris ensata var. spontanea. The protected plant species which are categorized by the Ministry of Environment were recorded only Lilium cernum. The Korean endemic plant species were recorded as 22 taxa; 12 families, 21 genera, 20 species 1 varieties, and 1 forma. Among them the plant species such as Cephalotaxus koreana, Abies koreana, Hosta capitata, Polygonatum lasianthum var. coreanum and Tricyrtis dilatata are representative ones in the region.

During the course of the field trip to Mt. Baekdu and Manchurian region especially along the border of North Korea, young flower buds were collected and fixed to analyze the meiotic configuration of chromosomes and to discuss the cytotaxonomic characteristics of these areas. A total of 29 taxa with 31 populations of vascular plants were analyzed chromosomally. Among them, 26 taxa with 28 populations were collected from Mt. Baekdu which include Papaver radicata var. pseudoradicata, Bupleurum euphorbioides, Oplopanax elatus, Silene jenisseensis, and Gentiana jamesii and three taxa collected from Manchurian region which include Scrophularia buergeriana, Ostericum grosseserratum and Callistephus chinensis. The first report of chromosome numbers were provided here for those species of Artemisia lagocephala as 2n = 9II, Cacalia komaroviana as 2n = 30II, Chrysanthemum zawadskii var. alpinum as 2n = 27II and Rodiola rosea as 2n = 11II,

The flora in the region of Songnisan National Park ($N36^{\circ}28^{\prime}05^{{\prime}{\prime}}{\sim}36^{\circ}46^{\prime}38^{{\prime}{\prime}}$, $E\;127^{\circ}47^{\prime}06^{{\prime}{\prime}}{\sim}127^{\circ}57^{\prime}50^{{\prime}{\prime}}$) was surveyed from April 2000 to July 2006. Vascular plants in 26 collections included a total of 723 taxa: 115 families, 392 genera, 629 species, 4 subspecies, 72 varieties and 18 forms. Ninety-three of these taxa were first records for the region. In the flora of Songnisan National Park, 27 taxa were Korean endemic plants, 19 taxa were rare and endangered plants as designated by the Korea Forest Service. Forty-five of the taxa were with the levels III, IV, V in the floristic regional indicator plants which was designated by Korean Ministry of Environment, and 29 taxa were alien plants now naturalized in Korea. Owing to their unusual phytogeography and low number of populations, the taxa Crypsinus hastatus (Thunb.) Copel., Paeonia japonica (Makino) Miyabe & Takeda, Jeffersonia dubia (Maxim.) Benth. & Hook.f. ex Baker & S.Moore, Bupleurum euphorbioides Nakai, Phacellanthus tubiflorus Siebold & Zucc., Lilium cernuum Kom., Gastrodia elata Blume and Cephalanthera erecta var. subaphylla (Miyabe & Kud ) Ohwi were considered the most important. Based on these results, it is clear that appropriate plans to conserve the natural habitat of Songnisan National Park must be made immediately.

The flora of Oesorak in the Soraksan National Park including Chombongsan(Mountain) and Kwanmobong(Peak) were surveyed from February to August, 1996. These areas have very rich and diverse flora;620 taxa with 89 families, 321 genera, 526 species, 2 subspecies, 89 varieties and 3 forms in the Oesorak, 404 taxa with 251 genera, 350 species, 1 subspecies, 51 varieties and 2 forms in the Chombongsan(Mountain), 286 taxa with 206 genera, 233 species, 1 subspecies, 50 varieties and 2 forms in Kwanmobong(peak). The Oesorak had very distinct floristic characteristics such as the wild habitats of Asarum maculatum(Aristolochiaceae) and Ilex macropoda(Aquifoliaceae). In the phyorgeographical point of view, the six species such as Sapium japonicum (Euphorbiaceae), Euphorbia joldini(Euphorbiaceae), Ilex macropoda (Aquifoliaceae), Styrax japonica (Styracaceae), Carex sideros ticta (Cyperaceae) and Asarum maculatum (Aristolochiaceae) were naturalized into this region, while the 17 taxa such as Abies neprolepis(Pinaceae), Pinus pumila(Pinaceae), Thuja koraiensis(Cupressaceae), Allium senescens(Liliaceae), Lilium distichum(Liliaceae), Saxifraga punctata(Saxfragaceae), Rosa marretii(Rosaceae), Bupleurum euphorbioides(Umbelliferae), Androsace cortusaefolia (Primulaceae), Peducularis mandshurica(Scrophulariaceae) and Leontopodium coreanum (Compositae) were distrivuted to this region. The colonizing weedy species such as Ixris repens (Compositae) were distributed to this region. The colonizing weedy species losa(Labiatae) and Rosa rugosa(Rosaceae) were naturalized into ca. 900m at sea level mainly due to the sand soil from the seashore. Mountain roadbed is susceptible than other areas to the slippery road problems, due largely to snow and rain, particularly during winter. Sand soils from seashore are utilized to minimize this slip in traffic operation.
