Abstract

As a result of investigating the plant distribution of Mt. Geumsan, Namhae, considering the direction, topography, altitude, accessibility,etc., a total of 693 taxa of vascular plants, including 117 families, 373 genera, and 602 species, 5 subspecies, 72 varieties, and 14forma appeared in 7 sections. Among them, a total of 46 taxa of pteridophyta, including 11 families, 24 genera, 45 species, 1 variety,a total of 15 taxa of gymnosperms, including 4 families, 6 genera, 12 species, 3 varieties, and a total of 632 taxa of angiosperms,including 102 families, 343 genera, 545 species, 5 subspecies, 68 varieties, 14 forma appeared. As for rare plants designated by theKorea Forest Service, 21 taxa, including 18 families, 18 genera, 20 species, 1 varieties were appeared. By type, for rare plants, theCR grade was 6 taxa with Isoetes japonica, Magnolia kobus, Prunus × yedoensis, Utricularia uliginosa, Metanarthecium luteoviride,Dendrobium moniliforme etc., the EN grade is Cymbidium macrorhizon and the VU grade is Taxus cuspidata, Drosera rotundifolia,Wisteriopsis japonica, Utricularia bifida etc. in 4 taxa, LC the grades are Selliguea hastata, Abies koreana, Asarum maculatum, Corylopsiscoreana, Viola albida, Chionanthus retusu, Utricularia caerulea, Arisaema heterophyllum etc. 8 taxa, Alangium platanifolium andScrophularia koraiensis appeared in DD grade, so 18 families, 18 genera, 20 species, 1 variety, 21 taxa appeared. Three taxa, Cymbidiummacrorhizon, Metanarthecium luteoviride and Utricularia uliginosa, which were designated as Class II organisms, appeared. Koreanendemic plant incorporated 18 taxa, including 14 families, 17 genera, 17 species, 1 variety. Floristic regional indicator plant incorporated 107 taxa, Grade Ⅴ was 11 taxa such as Isoetes japonica, Millettia japonica, Metanarthecium luteoviride etc., Grade Ⅳ was 11 taxasuch as Drosera rotundifolia, Corylopsis gotoana var. coreana, Sanguisorba longifolia etc., Grade Ⅲ was 23 taxa such as Selaginellainvolvens, Dryopteris fuscipes, Scrophularia koraiensis etc., Grade Ⅱ was 13 taxa such as Equisetum hyemale, Crypsinus hastatus,Rhaphiolepis indica var. umbellata etc., Grade Ⅰ was 49 taxa such as Lygodium japonicum, Dicranopteris pedata, Euonymus macropterusetc., including 58 families, 91 genera, 102 species, 1 subspecies, 4 variety appeared. Exotic plants incorporated 65 taxa, including 28families, 55 genera, 64 species, 1 subspecies, and the urbanization index was 11.2%, and the naturalization rate was 6.1%. This waslower than Korea's average naturalization rate of 10.3%.
