The purpose of this study was to identify the ecological characteristics of Namhan Mountain Fortress Walls vascular plants through investigation and analysis of Namhan Mountain Fortress Walls and to provide basic data when establishing a plan for conservation and management of Namhansanseong Fortress Wall vascular plants. The result of this survey revealed 249 taxa composed of 77 families, 169 genera, 222 species, 5 subspecies, 19 varieties and 3 forms. In terms of life form of Namhan Mountain Fortress Walls, the appearance rate of Hemicryptophytes(H) was high. Rare plants was 1 taxa and Korea endemic plants was 5 taxa. The total number of floristic regional indicator plants was 15 taxa, gradeI 9 taxa, gradeII 2 taxa, gradeIII 3 taxa, gradeIV 1 taxa. Among them, Polygala tatarinowii Regel is considered to the most important(gradeIV), and it is first description because in Gyeonggi-do, as no additional forms have been confirmed other than this site. Plants identified as rock vegetation were found in 21 taxa. Invasive alien plants were identified 20 taxa. Plants distributed on the walls of Namhan Mountain Fortress, such as Aconitum longecassidatum Nakai, Clematis heracleifolia DC. var. tubulosa (Turcz.) Kuntze, Hylotelephium spectabile (Boreau) H.Ohba and Polygala tatarinowii Regel etc, are feared to decrease the number of species and individuals due to the loss of walls, the spread of invasive alien plant and human interference, so conservation and management measures are needed.

This study was carried out to investigate the flora of Mt. Seoungma (Gyeonggi-do). The vascular plant were collected 13 times (from March to October 2011), and 384 taxa in total were identified, including 94 families, 260 genera, 340 species, 5 subspecies, 37 varieties and 2 forms. Korean endemic plants of this area were nine taxa; Clematis brachyura, Rhododendron mucronulatum, Forsythia koreana, Paulownia coreana, etc. Rare plants (IUCN) by the Korean Forest Service and Korean National Arboretum three taxa were recorded; one Critically Endangered species (CR), Prunus yedoensis, one Vulnerable species (VU), Epimedium koreanum, one Least Concemed species (LC), Phacelurus latifolius. The floristic regional indicator plants found in this area were 15 taxa comprising two taxa of grade V and III, one taxa of grade II, 10 taxa of grade I. Furthermore, therophytes (28.3%), hemicryptophytes (23.0%), hydrophytes (14.3%) showed high proportional ratio in life form spectrum. The naturalized plants were identified as 43 taxa and the percent of naturalized index (NI) was 11.2% of total 384 taxa vascular plants. The vegetation status of investigated area was comparatively well conserved, but the degree of damage was increasing rapidly by the disturbances of human beings. Therefore, a long-term monitoring of vegetation changes and movement grasp must become accomplished.

Mt. Taegi (1,261.4 m) located in Gangwon-do, is a geographically important region for plant biodiversity. But the biodiversity of Mt. Taegi has been seriously damaged by the invasion of foreign plants, the development of forests and so on. We conducted 21 field surveys between April and August in 2008 and March and October in 2018 to investigate the vascular flora in Mt. Taegi. Total 662 taxa were identified including 96 families, 338 genera, 580 species, 4 subspecies, 66 varieties and 12 formas. Among them, 28 taxa were Korean endemic plants and 8 taxa were rare plants designated by the Korea Forest Services, and 11 taxa were listed on the Red list of endangered plants and 127 taxa were designated as the floristic regional indicator plants according to the Ministry of Environment. The alien plants were 45 taxa, including R. acetosella that is the ecosystem disturbing species.

The flora of vascular plants in the Gibaeksan Mt. County Park and its neighboring mountains, located at the boundary between Geochang-gun and Hamyang-gun in Gyeongsangnam-do province in Korea, were surveyed for a total 46 times from April to September of 2011, in July of 2012, and from April of 2015 to August of 2018. The result of this survey revealed 659 taxa composed of 107 families, 346 genera, 583 species, 14 subspecies, 46 varieties and 6 forms. Among them, 25 taxa were endemic plants to Korea, and 18 taxa were rare and endangered plants of Korea. The floristic regional indicator plants including cultivated plants were 5 taxa of grade V, 5 taxa of grade IV, 29 taxa of grade III, 30 taxa of grade II and 38 taxa of grade I. Forty-three taxa of alien plants were found in this area. In addition, 500 taxa out of a total of 649 taxa were categorized by usage into eight groups, including among others an edible group containing 257 taxa, a medicinal group containing 206, a pasturing group containing 220, and an ornamental group containing 84, with some taxa belonging to more than one group. The flora of this surveyed area belongs to the southern province among the floral provinces of the Korean Peninsula.

This study was carried out to investigate the flora and vegetation of Yokjido Island in Tongyeong-si, Korea. Vascular plants collected six times (from March of 2015 to January of 2016) were identified as 547 taxa in total, including 113 families, 354 genera, 487 species, four subspecies, 50 varieties, four forms and two hybrids. The first records from this region contained 314 taxa. In the flora of this area, endemic Korean species numbered eight taxa, and the red list of vascular plants according to the IUCN valuation basis numbered six taxa. In addition, 86 taxa of floristic regional indicator plants specially designated by the Ministry of Environment are included. Among the species investigated in this survey, 99 taxa were identified as specific species bio-geographically as compared floras of other terrestrial regions; 97 taxa of plants in southern areas and two taxa of limited distribution plants on the Korean Peninsula. In all, 74 naturalized plants were recorded in the investigated area. Samples of the forest vegetation of Yokjido Island were mainly classified as Pinus thunbergii community and the Alus firma community. Vertical structures of the communities were stable, and a DBH-class analysis showed that the dominant tree species would be maintained. If disturbance factors such as thinning could be halted, the composition of woody species and herbaceous species would change.

Baekdudaegan, the largest mountain range in eastern Asia, is a biodiversity hotspot in Korea that may have served as a glacial refugium. This study presents the flora of vascular plants on Deok-chi upto the Yuk-sim-nyeong area of the Baekdudaegan conservation area. The survey area was divided into four subareas and fieldwork was conducted for a total of twelve days in 2015. Voucher specimens were collected during the survey and were deposited at Daejeon University. A list of vascular plants was prepared based on the voucher specimens. The results of the survey showed that a total of 441 taxa, consisting of 100 families, 265 genera, 398 species, 9 subspecies, 32 varieties, and 2 forms, were found in the survey area. There was one endangered species, Aconitum coreanum, in the Bonghwasan Mt. area. Sixteen endemic taxa, 74 floristic regional indicator plants, as designated by the Ministry of the Environment, and eleven naturalized plants were distributed. The results of this study can serve as basic information to establish conservation and management plans for the Baekdudaegan conservation area.

The flora of vascular plants in Sumeunmulbaengdui wetland located in Hallasan National Park was surveyed 9 times from September, 2010 to May, 2014. This survey resulted in 236 taxa in total composed of 202 species, 2 subspecies, 27 varieties and 5 forms of 148 genera under 69 families. They were categorized by their life forms into 8 groups of 37 megaphanerophytes, 26 nanophanerophytes, 2 epiphytes, 3 chamaephytes, 84 hemicryptophytes, 33 geophytes, 21 hydrophytes, 30 therophytes. Among them, 10 taxa of Korean endemic plants and 9 taxa of rare and endangered plants were included. In addition, the floristic regional indicator plants were 43 taxa comprised of 3 taxa of grade V, 7 taxa of grade IV, 12 taxa of grade III, 8 taxa of grade II and 13 taxa of grade I. 2 species of alien plants, Erechtites hieracifolia Raf. and Taraxacum officinale Weber were found. Sustainable interest and protective measures to Sumeunmulbaengdui wetland are required, since this area is comparatively larger in size and higher in plant diversity than other Ramsar wetlands in Jeju-do Province.
