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.

The flora consists of 334 taxa, 86 families 246 genera 297 species 34 varieies and 3 forms in total results from 5 sites in this study. Korean endemic species were confirmed 8 taxa. No rare and endangered species were found in this study. The 2 taxa of the fourth grade of specially designated plants announced the Ministry of Environment were investigated and 8 taxa of the third grade were confirmed. In totally, 24 taxa that are specially designated plants announced the Ministry of Environment including the first and the second grade taxa. 25 taxa of alien naturalized plants were confirmed.

In order to illustrate the flora of vascular plants distributed in the Five West Sea Islands, the authors collected vascular plants intensively in Baengnyeongdo and Socheongdo from May 2015 to August 2015. Also, voucher specimens from the previous investigations (Daecheongdo, Yeonpyeongdo and Soyeonpyeongdo) deposited at the Korean National Arboretum (KH) were re-identified. All of them were comprised of 108 families, 420 genera, 728 species, 6 subspecies, 86 varieties and 14 forms, totally 834 taxa. There were 8 endemic taxa, 19 rare taxa, 27 taxa for floristically specific to Korean floral zone except the species of their 1st and 2nd degree, and 107 naturalized taxa among the collected plants. Owing to their unusual phytogeography and low number of populations, the taxa Rosa maximowicziana Regel, Allium anisopodium Ledeb., Bistorta pacifica (Petrov ex Kom.) Kom., Scorzonera austriaca subsp. glabra (Rupr.) Lipsch. & Krasch. ex Lipsch., Iris dichotoma Pall., Amsonia elliptica (Thunb.) Roem. & Schult. were considered the most important. Based on these results, it is clear that appropriate plants to conserve the natural habitat of the Five West Sea Islands must be made immediately.

The flora of resource plants in Middle and Northern region of Yangsan-si were investigated for 7 times from March to Sept., 2009. The study indicated that, based on voucher specimens, the flora of this area consist of 427 taxa in total; 90 families, 256 genera, 376 species, 4 subspecies, 41 varieties and 6 forms. The resource plants in this area were categorized by their use into 9 groups inclusive of 1 unidentified group. Resources plants which were investigated in this area were 167 edible, 132 pasturing, 118 medicinal, 98 stainable, 52 ornamental, 15 timber, 6 fiber, 2 industrial taxa and 101 unknown resource plants, respectively. Also, there were remarkable plants such as 16 taxa of Korean endemic plants and 36 taxa of specific plants which were designated by the Ministry of Environment. Furthermore, 22 taxa of naturalized plants were observed in this investigated area where Urban Indexn UI) was 8.9%. Although the ecological status of investigated area was comparatively well conserved, the degree of (UI) was relatively high. Based on the results of this investigation, UI has been rapidly increased due to urbanization and construction of recreation objects in this area.

This study was conducted to prepare basic data by analyzing the biological values and environmental factors of algific talus slope in order to respond to climate change due to the greenhouse effect, and to establish plans for forest biodiversity preserving and managing. Meteorological information was measured and the flora of vascular plants were investigated for six algific talus slope by seasonally from 2020 to 2021. As a result of the investigation, the temperature of all 6 algific talus slope was lower than that of the area where the algific talus slope was located in summer, and flora was 101 families, 350 genera, 621 species, 18 subspecies, 57 variants, 7 varieties, 703 taxa. In sum, it is judged that the algific talus slope has sufficient reasons and value to be preserved because it has excellent micrometeorological value from the cold wind blowing in summer and phytogeographical value in which various plants live in a small area. However, in spite of such an important area, the management of algific talus slope is insufficient, and the algific talus slope is damaged or the ecosystem of the algific talus slope is disturbed. Therefore, it is necessary to establish a systematic conservation and management plan by designating algific talus slope as a forest genetic resource reserve and OECM.
