Distribution of Vascular Plants in the Area of Muryongsan (mt.)

Abstract

The total number of taxa examined by this study was 489 taxa of 96 families, 395 genus, 394 species, 2 subspecies, 72 mutants, 17 taxa, 1 hybrid and 3 cultivars. Only the Utricularia yakusimensis was an endangered species as designated by the Ministry of Environment in the study area, and 5 species, including the Acorus calamus, Iris ensata var. spontanea, Drosera rotundifolia, Ultricularia racemosa and Lysimachia coreana were found as endangered species as designated by the Korea Forest Service. According to the IUCN standards, a single species of Utricularia yakusimensis among CR species, Drosera rotundifolia and the Pogonia minor among VU species and the Lysimachia coreana, Ultricularia racemosa, Acorus calamus and the Iris ensata var. spontanea among LC species were detected. The specialized plants in this study included 25 species in Class-I, 3 in Class-II, 7 in Class-III and 3 in Class-IV at a total of 38 species. In terms of naturalized plants in Muryongsan (mt.), a total of 27 taxa of 11 families and 24 genus were confirmed, and the naturalization rate of the total 489 species was calculated to be 5.5%. The area studied requires a high level of monitoring and restorative methods, since the area experience high level of nondiscriminatory usage by the residents of the Ulsan region, which has led to high degree of damage.
