This study was carried out to investigate the distribution of vascular plants and their use from 2007 to 2009 in Mt. Unmum(Cheongdo-gun, Gyeongsangbuk-Do). The vascular plants were summarized as 605 taxa including 98 families, 304 genus, 514 species, 3 subspecies, 68 varieties, and 20 forma. Among the investigated 605 taxa, 21 rare and endangered plants, 29 Korean endemic plants were included. Based on the list of specially designated plants by Ministry of Environment, 70 taxa included Iris odaesanensis and Gastrodia elata were recorded in the investigated area. The naturalized plants were identified as 23 taxa and the percent of naturalized index(NI) was 3.8% of total 605 taxa vascular plants. Usage of 605 taxa were consists of 225 taxa(37.2%) of edible plants, 191 taxa(31.6%) of medicinal plants, 64 taxa(10.6%) of ornamental plants, 46 taxa(7.6%) of pasture plants, 18 taxa(3.0%) of timber plants, 14 taxa(2.3%) of fiber plants, and 3 taxa(0.5%) of industrial plants. To management of natural resource, we suppose that it is required to establish an ecological learning area to minimize human disturbance and an effective managemet strategy by continuous monitoring for ecosystem change.

The purpose of this study is to provide the baseline data for conservation and management of Korean forest ecosystem by surveying and analyzing the vascular plants distributed from Gitdaebaegibong to Cheonghwasan in Baekdudaegan Mountains. The results are as follows. The numbers of vascular plants in the whole survey section were summarized as 771 taxa including 103 families, 379 genera, 623 species, 4 subspecies, 121 varieties and 23 forms. There were 377 taxa in A-section, 395 taxa in B-section, 278 taxa in C-section, 325 taxa in D-section, 534 taxa in E-section, and 406 taxa in F-section. The rare plants were 32 taxa including Megaleranthis saniculifolia, Rodgersia podophylla, Iris ensata var. spontanea, and Gastrodia elata. In IUCN Red List categories, there were 1 taxon of CR, EN, and DD each, 11 taxa of the VU, and 18 taxa of the LC. The Korean endemic plants were 26 taxa including Asarum versicolor, Clematis fusca var. coreana, Vicia chosenensis, Stewartia pseudocamellia, Carex okamotoi, and Luzula sudetica var. nipponica. The specific plants by floristic region were 143 taxa including 3 taxa of grade V, 12 taxa of grade IV, 41 taxa of grade III, 42 taxa of grade II, and 45 taxa of grade I. The naturalized plants were 41 taxa including Rumex crispus, Ailanthus altissima, Erechtites hieracifolia, Erigeron annuus, and Poa pratensis. The invasive alien plants were 4 taxa including Rumex acetocella, Sicyos angulatus, Ambrosia artemisiifolia, and Aster pilosus. The plants adaptable to climate change were 43 taxa including 14 taxa of endemic plants, 2 taxa of southern plants, and 27 taxa of northern plants.

In this study, we investigated the flora of Jeonggwangsan Mt. (Yongin, Korea) from May of 2015 to September of 2016. Through 14 independent field investigations, we identified a total of 367 taxa of vascular plants, including 89 families, 234 genera, 323 species, six subspecies, 34 varieties, and four formae. Eight taxa were endemic to Korea, while 27 were naturalized in Korea. Nineteen taxa were the floristic regional indicator plants in Korea: four in Rank VI, four in Rank III, two in Rank II, and nine in Rank I. A total of 59 taxa were designated as controlled Korean biological resources, requiring special permission for export to outside countries. Two taxa were listed on the Red List of Korea, including one Near Threatened (NT) taxon (Hololeion maximowiczii Kitam.) and one Least Concern (LC) taxon (Iris minutoaurea Makino).

A floristic study on the vascular plants from Juwangsan National Park was conducted 13 times in total, from March to October 2017. Based on the voucher specimens and pictures, it was revealed that the vascular plants in this region comprised 758 taxa: 112 families, 399 genera, 672 species, 4 subspecies, 72 varieties, and 10 forma. Among these plants, 221 taxa were recorded for the first time from this region. The taxa in category II of endangered plants designated by the Korean Ministry of Environment were two taxa, including Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. and Epilobium hirsutum L. The rare plants numbered 5 taxa designated by National Institute of Biological Resources were also found. 20 taxa of Korean endemic plants including Corydalis alata B.U.Oh & W.R.Lee, Iris odaesanensis Y.N.Lee, and Scrophularia cephalantha Nakai were investigated in this region. 40 taxa of floristic regional indicator plants in the 3rd to the 5th degrees were identified. Naturalized plants of 55 taxa were recorded, and 3 taxa of ecosystem disturbance plants, which were Ambrosia artemisiifolia L., Aster pilosus Willd., and Lactuca scariola L., also found.
