This study aims to investigate the flora of Mt. Cheonma (Namyangju-si, Gyeonggi-do, Korea), including Korean endemic, rare and endangered plants. To support the biodiversity and usefulness of this investigation, we checked the red list plants, floristic regional indicator plants, climate change adaptation target plants and naturalized plants, and compared composition of plant species in Mt. Cheonma with nearby mountains. Totally, we performed 22 field investigations from April 2012 to October 2014. The number of vascular plants in this region is 433 taxa and comprised of 94 families, 266 genera, 378 species, 2 subspecies, 46 varieties, and 7 forms. Among them, there are 13 endemic plants designated by Korean Forest Service, whereas only 10 taxa are endemic species by Korean Ministry of Environment (KME). According to the IUCN criteria, there are 12 rare and endangered plants composed of 9 Least Concerned (LC), 2 Vulnerable species (VU), and one Endangered species (EN) found by Korea National Arboretum (KNA). Meanwhile, 8 taxa including 7 Least Concerned (LC) were found in Red List of KME. The floristic regional indicator plants designated by KME were 49 taxa. In addition, there are 14 taxa in The Adaptable to Climate Change Plant List designated by KNA, while only 19 taxa are naturalized plants. Generally, there are 190 common taxa in Gwangju Mountains area, and only 51 taxa are distributed in Mt. Cheonma.

The purpose of this study is to offer the raw data for establishing the management and restoration plan by objective surveying and analysing the flora distributed in Seoak District, Gyeongju National Park, Korea. The flora summarized as 411 taxa including 92 families, 285 genera, 363 species, 2 subspecies, 41 varieties and 5 forms. The rare plants designated by Korea Forest Service were 2 taxa including Exochorda serratifolia and Potentilla discolor. The Korean endemic plants were 3 taxa including Philadelphus schrenkii, Lespedeza maritima and Weigela subsessilis. The specific plants by floristic region were 16 taxa including Asplenium sarelii, Pyrrosia petiolosa, Vitex negundo var. incisa and so forth. The target plants adaptable to climate change were 2 taxa including Lespedeza maritima and Carpesium macrocephalum, and the plants with approval for delivering oversea were 4 taxa including Exochorda serratifolia, Glycine soja, Lespedeza maritima and Weigela subsessilis. The naturalized plants were 51 taxa including Phytolacca americana, Viola papilionacea, Lamium purpureum and so forth. The invasive alien plants were 3 taxa including Ambrosia artemisiifolia, Aster pilosus and Lactuca scariola. NI(Naturalized Index) was 12.4% of all 411 taxa of surveyed flora in this study and UI(Urbanized Index) was 15.9% of all 321 taxa of naturalized plants in Korea. Potentilla discolor in rare plant, Philadelphus schrenkii in endemic plant and Dictamnus dasycarpus in specific plant were established the conservation plan. Whereas, invasive alien plants such as Ambrosia artemisiifolia, Aster pilosus and Lactuca scariola should be removed as soon as possible. The damaged sites in Seoak District were divided between wildfire area and farmland. To restore a forest fire site, we will have to apply a natural renewal and community planting. In case of farmland, we will have to do ecological planting using native species and constrcut a forest wetland.

This study presents the flora of nonvascular plants (bryophytes) and vascular plants within the Wangpicheon Ecosystem and Landscape Conservation Area in Korea. The time of the survey was divided into four seasons. The fieldwork was conducted for a total of 18 days from November of 2016 to October of 2017. The land plants in the Wangpicheon conservation area were identified as 758 taxa with 164 families, 455 genera, 698 species, 10 subspecies, 47 varieties and 3 forms. Among them, bryophytes amounted to 122 taxa and vascular plants numbered 636 taxa. Native plant amounted to 693 taxa. In total, there are 113 floristic target species in Korea, including one level V taxon, in this case Swertia wilfordii; six level IV taxa; 31 level III taxa; 38 level II taxa; and 37 level I taxa. There are nine endemic plants, including Sillaphyton (=Peucedanum) podagraria, which is the endemic genus; two rare plants; fifteen northern plants; and one southern plant as target plants adaptable to climate change. Also, there are forty-six naturalized plants and five ecosystem-disturbance organisms. The results of this study suggest several species that should be preserved and can serve as basic information with which to establish conservation and management plans for the Wangpicheon conservation area.

This study aimed to investigate the flora of Jinjosan Mt. (Uljin-gun, Gyeongsangbuk-do). The vascular plants were surveyed 9 times between March 2019 and April 2020. The results of this survey revealed a total of 414 taxa comprising of 87 families, 274 genera, 365 species, 12 subspecies, 32 varieties, and 5 forms. Among them, 9 taxa were Korean endemic plants and 5 taxa were rare plants of Korea. In addition, the specific plants by floristic region were 66 taxa including 1 taxon of grade IV, 18 taxa of grade III, 24 taxa of grade II, and 23 taxa of grade I. Additionally, eight taxa were classified as plants adaptable to climate change.
