  • Korean L. leiolepis of the genus Leontopodium could be discriminate from the foreign L. alpinum using random amplified polymorphic DNA (RAPD). Among the 12 URP markers used for the detection, the URP-5 marker and the URP-7 marker detected polymorphic DNA bands, ranging from 400-1000 bp in the size of amplified DNA fragments.

  • Five species of the genus Leontopodium are recognized in Korea, but their taxonomic positions have been controversial. To clarify the taxonomic entity of these Korean species, we examined their morphological characters based on herbarium specimens and field observations. Valuable distinguishing characters for identification included the plant height, the basal shape of cauline leaves, the type and position of inflorescence, the types of hairs, the presence of leaves at the anthesis, and hairs on the phyllaries. Based on our observations, we were able to determine the taxonomic relationships between L. japonicum and its relatives, L. coreanum and L. hallaisanense. We also included the morphological characters of L. seorakensis in continuous variations of L. leiolepis, which we treated as synonyms. Consequently, we classified these Korean Leontopodium species into four taxa - L. coreanum var. coreanum, L. coreanum var. hallaisanense, L. leiolepis, and L. leontopodioides - with appropriate descriptions and illustrations.

  • The somatic chromosome number of four Korean species of Leontopodium were investigated. The chromosome number of L. leiolepis (2n = 24) is reported here as for the first time. The chromosome number of L. japonicum (2n = 28) is not varied among the 3 populations on the Korean Peninsula, but that condition is different from the previous reports for Korea (2n = 26) and Japan (2n = 21, 26). L. hallaisanense and L. japonicum, both of which are in sect. Nobilia and similar to each other in gross morphology, have the same chromosome number of 2n = 28. On the other hand the chromosome number of Korean L. leontopodioides (2n = 24) is different from that in Russian reports (2n = 26). The chromosome numbers of all Korean species of the genus Leontopodium could be inferred as tetraploid or aneuploid.

  • To investigate the structure and the conservation strategy of natural forest at Dosolbong area in Mt. Sobaek, 20 plots(400$m^2$) set up with random sampling method. Three groups were classified by cluster analysis. High positive correlations was proved between Acer pseudo-sieboldianum and Tilia amurensis, Weigela subsessilis, Corylus heterophylla var. thunbergii and Stephanandra incisa, Lespedeza bicolor and Styrax obassia, and high negative correlations was proved between Rhododendron schlippenbachii and Symplocos chinensis, Carpinus cordata. Species diversity(H') of investigated area was calculated 2.2521-2.3772. Leontopodium japonicum community at Dosolbong area in Mt. Sobaek should be conserved.

  • Hyangro-bong is located on the northern side of the civilian access control line and therefore has gone through natural ecological succession without human interference. Currently, it forms a distinctive natural ecosystem in which rare wild animals and plants are various. It is located in the Baekdudaegan mountain system and plays an ecologically important role as a bridge that connects the Geumgang mountain and Seorak mountain. This study investigated the flora of the eastern parts, Forest Genetic Resources Reserve Area, of Hyangro-bong. A total of 363 vascular plants that belonged to 77 families, 206 genera, 310 species, 3 subspecies, and 47 varieties were found in the study area. Rare and endangered plants identified in this study included the critically endangered Swertia wilfordii and endangered Irisuniflora var. caricina. Furthermore, 4 vulnerable species, Hanabusaya asiatica, Codonopsis pilosula, Leontopodium japonicum, and Taxus cuspidata, were found. A total of 7 families and 14 taxa including Aconitum pseudolaeve and Clematis fusca var. coreana were confirmed as endemic plants. Naturalized plants belonging to 4 families, 11 genera, and 13 species were distributed along the Hyangro-bong forest roads.

  • 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㎢.

  • This study suggested suitable soil textures that is proper to propagate native plants to manage and restore barren land in DMZ. Germination tests were conducted for 16 native herbaceous plants growing in the DMZ border area in accordance with FAO-BI (Biodiversity International) standards, and the germination rate and T50 in vitro were investigated. In order to examine the germination characteristics according to the soil textures, we used gravel, bed and mixed soil and investigated the germination characteristics under ordinary room temperature conditions in the greenhouse. As a result, it was observed that the germination rate in the greenhouse was significantly decreased compared to the germination rate in vitro of the species advertised due to soil textures. T50 between the in vitro and each soil texture showed significant differences whereas T50 between soil textures alone did not in all species advertised. The germination rate in vitro of Aster koraiensis, Dendranthema zawadskii var. latilobum, Hosta clausa, and Hosta minor there was no significant difference compared to ordinary room temperature conditions. In addition, as the germination rate is demonstrated more than 70%, which is relatively higher than other species advertised, it is considered to have strong environmentally adaptable. On the other hand, considering that the 6 species of Leontopodium coreanum, Plantago major, Potentilla chinensis, Sedum kamtschaticum, Sedum latiovalifolium, and Veronica kiusiana demonstrated less than 50% of germination rate in vitro, it is expected to be difficult to propagate without pre-treatment. In order to use these 6 species as restoration material plants, it needs to be considered to pre-treat to improve germination rate, or to enhance the vitality of seeds by improving the seed gathering period and storage method.
