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.
