This study was carried out to survey the vascular plants of Baekdudaegan Arboretum area. The results are as follows. The numbers of flora in this study area were summarized as 655 taxa including 95 families, 332 genera, 567 species, 5 subspecies, 72 varieties and 11 formas. The rare plants were 17 taxa including Parasenecio firmus, Rhododendron micranthum, Iris odaesanensis, Lysimachia coreana and so forth. The Korean endemic plants were 16 taxa including Weigela subsessilis, Heloniopsis koreana, Salix koriyanagi, Vicia chosenensis and so forth. Plants Adaptable to Climate Change were Northern plants 18 species, Southern plants 2 species, endemic plants 10 species. The naturalized plants were 44 taxa and ratios of naturalized index and urbanization index were estimated Core area 10.2% and 4.9%, Mt. Munsu 4.9% and 2.3% and Mt. Okseok 5.5% and 2.6%. The floristic regional indicator plants found in this area were 3taxa(2.5%) of grade Ⅴ, 12taxa(11.0%) of grade Ⅳ, 22taxa(20.2%) of grade Ⅲ, 35taxa(32.1%) of grade Ⅱ. In life forms, hemicryptophytes were The most dominant. Next was a Therophytes. In addition, 492 taxa were categorized by usage into 8 groups, as follows: Edible 239taxa(36.5%), Fiber 10taxa(1.5%), Industrial 1taxon(0.2%), Miscellaneous 183taxa(27.9%), Ornamental 65taxa(9.9%), Pasturing 259taxa(39.5%), Siscellaneousg 14taxa(2.1%) and Timer 21taxa(3.2%).

This research was performed for the purpose of providing useful and base data and preservation strategy of growth characteristics of Rhododendron micranthum. From the result of research, wild growth area of Rhododendron micranthum was discovered near steep forest road on 695∼901m in altitude above sea level of Baekdu-daegan National Arboretum. Vegetation colony structure of SiteⅠwas resulted in Pinus densiflora(tree stratum M.I.P.=45.3%) is dominants, Betula schmidtii(arborescent M.I.P.=9.8%) is second dominant, and SiteⅢ resulted in Pinus densiflora(tree stratum M.I.P.=30.5%) is dominants, Betula schmidtii(arborescent M.I.P.=10.3%) is second dominant. SiteⅡ resulted in Betula schmidtii(arborescent M.I.P.=30.4%) is dominants and Pinus densiflora tree(tree stratum M.I.P.=8.3%) is second dominants. For herbs, it was researched that the rate of one year herb of chrysanthemum family(10), rice family(3), sedge(2) was higher than near forest area. Among Species diversity index, that of Shannon was in range of 0.7348∼1.1090. After comparing this with similar area, this value was relatively low. Dominance analysis result was analyzed that various groups are evenly distributed. Monthly highest average temperature is 23.9° in Site A and Site B, and monthly lowest average temperature is -4.5℃ in SiteⅠand -4.7℃ in SiteⅡ. Monthly maximum average humidity is 85.6% in SiteⅠand 83.2% in SiteⅡ. Monthly minimum average humidity is 60.9% in SiteⅠand 60.8% in SiteⅡand it showed that these 2 area are located far away but have similar temperature and humidity characteristic and climate environment is similar. It was analyzed that humidity is high with the result of annual average humidity is over 60%. In growth characteristic, it showed that doubt damage of Stephanitis pyrioides, exposure of roots, peeled bark was discovered and supplement on this is urgent.
