Distribution of vascular plants in the area of Muryongsan (Mt.).

Abstract

A total of 489 taxa of 96 families, 395 genera, 394 species, 2 subspecies, 72 mutants, 17 taxa, 1 hybrid and 3 cultivars of vascular plants from Mt. Muryongsan, Korea Republic, were examined. Only 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, Utricularia 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, Utricularia racemosa, Acorus calamus and the Iris ensata var. spontanea among LC species were detected. The specialized plants 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 Mt. Muryongsan, a total of 27 taxa of 11 families and 24 genera 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 restoration methods, since the area experience high level of non-discriminatory usage by the residents of the Ulsan region, which has led to high degree of damage.
