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.

The flora in the region of Songnisan National Park ($N36^{\circ}28^{\prime}05^{{\prime}{\prime}}{\sim}36^{\circ}46^{\prime}38^{{\prime}{\prime}}$, $E\;127^{\circ}47^{\prime}06^{{\prime}{\prime}}{\sim}127^{\circ}57^{\prime}50^{{\prime}{\prime}}$) was surveyed from April 2000 to July 2006. Vascular plants in 26 collections included a total of 723 taxa: 115 families, 392 genera, 629 species, 4 subspecies, 72 varieties and 18 forms. Ninety-three of these taxa were first records for the region. In the flora of Songnisan National Park, 27 taxa were Korean endemic plants, 19 taxa were rare and endangered plants as designated by the Korea Forest Service. Forty-five of the taxa were with the levels III, IV, V in the floristic regional indicator plants which was designated by Korean Ministry of Environment, and 29 taxa were alien plants now naturalized in Korea. Owing to their unusual phytogeography and low number of populations, the taxa Crypsinus hastatus (Thunb.) Copel., Paeonia japonica (Makino) Miyabe & Takeda, Jeffersonia dubia (Maxim.) Benth. & Hook.f. ex Baker & S.Moore, Bupleurum euphorbioides Nakai, Phacellanthus tubiflorus Siebold & Zucc., Lilium cernuum Kom., Gastrodia elata Blume and Cephalanthera erecta var. subaphylla (Miyabe & Kud ) Ohwi were considered the most important. Based on these results, it is clear that appropriate plans to conserve the natural habitat of Songnisan National Park must be made immediately.

We investigated the flora of Gwanmae island and discussed important vascular plants found on the island. We made plant list using voucher specimens collected from Gwanmae island from 2016 to 2021 and deposited in CNU. There are 500 taxa in Gwanmae island, comprising 103 families, 307 genera, 461 species, 4 subspecies, 32 varieties and 3 forms. Eight endemic plants of Korea were found including Saussurea polylepis Nakai. There are 15 red list plants designated by Ministry of Environment including Cleisostoma scolopendrifolium (Makino) Garay and Woodwardia japonica (L. f.) Sm. There are total 126 taxa of floristic regional indicator plants including 4 taxa of level V such as Juniperus procumbens (Siebold ex Endl.)

This study was carried out to investigate the flora of Mt. Gilsangsan (Ganghwa-Isl.). The vascular plants were collected 14 times (from March to November 2012), and were identified as 595 taxa; 122 families, 359 genera, 529 species, 7 subspecies, 51 varieties, 2 forms and 3 hybrids. The plant formation of Mt. Gisangsan is the deciduous broad-leaved and conifer mixed forest which is the common one in the middle part of Korean peninsula. All most mountain covered with young secondary forest which is mainly composed of Pinus and Quercus. The family represented by the largest number of species diversity were Asteraceae (11.%), Poaceae (10.7%), Cyperaceae (6.38%), Fabaceae (3.86%) and Rosaceae (3.52%) respectively. Korean endemic plants of this area were 12 taxa; Asarum misandrum, Clematis brachyura, Philadelphus schrenkii, Forsythia koreana, Polygonatum infundiflorum, etc. The red list of vascular plants according to IUCN valuation basis were examined, endangered species (EN) Abies koreana, Near Threatened species (NT) both Wikstroemia trichotoma and Sparganium erectum, Least Concern species (LC) Platycladus orientalis, Swertia diluta var. tosaensis and Iris minutoaurea and by Not Evaluate species (NE) Polygonatum infundiflorum. The floristic regional indicator plants found in this area were 45 taxa comprising two taxa of grade V and VI, nine taxa of grade III, three taxa of grade II, 29 taxa of gradeI. The naturalized plants were identified as 64 taxa and the percent of naturalized index (NI) was 10.7% of total 595 taxa vascular plants. Ecosystem disturbance wild plants were consisted of eight taxa; Rumex acetosella, Sicyos angulatus, Solanum carolinense, Ambrosia artemisiifolia, Ambrosia trifida, Aster pilosus, Hypochaeris radicata and Lactuca scariola. Furthermore, therophytes (26.5%), hemicryptophytes (26.0%), Geophyte (14.0%) showed high proportional ratio in life form spectrum.

The vascular plants of the 15 sites of Taeanhaean National Park were identified as 493 taxa; 117 families, 326 genera, 436 species, 49 varieties, 6 form, 2 hybrids. The National Park area includes coastal areas and islands, these islands reflects well the floristic characteristics of coastal area and transition area of the middle province and the southern province. The study revealed that Ficus erecta Thunb., Machilus thunbergii S. et Z., Neolitsea sericea (Bl.) Koidz. and Eurya japonica Thunb. etc. were the mainly distributed species in the southern area while Rosa rugosa Thunb., Carex kobomugi Ohwi and Elymus mollis Trin., etc. were mainly distributed species over the coastal dune area. Deciduous and evergreens broad-leaved trees like Acer palmatum Thunb. ex. Murray, Euonymus japonica Thunb. and Camellia japonica L., etc. were all together distributed in Taeanhaean National Park. There are no any Endangered species designated by The Ministry of Environment were not found. The floristic special plants were recorded to a total of 53 taxa; that is, class I species (41 taxa) were containing as Vitex rotundifolia L. Fil., Arisaema heterophyllum Bl. and Arisaema ringins (Thunb.) Schott, etc, class II species (1 taxon) were Iris ensata var. spontanea (Makino) Nakai, class III species (7 taxa) were containing; Koelreuteria paniculata Laxm., Salsola collina Pall. and Daphniphyllum macropodum Miq., etc, class IV species (1 taxon) were Angelica japonica A.
