We conducted a total of 28 surveys from March to October 2016 in Gayasan National Park, to identify threatened plants for climate change, as well as for the effective management of biological organisms and resources against climate changes in Korea. Regarding threatened plants for climate change, we identified a total of 39 taxa, with 11 northern, 2 southern, and 26 taxa of concern. Among these taxa, 33 were identified as wild species. The species threatened by climate change located in the subalpine regions of Gayasan National Park were Abies holophylla Maxim., Abies koreana Wilson, Pinus koraiensis Siebold & Zucc., Betula ermanii Cham., Berberis amurensis Rupr., Rhododendron tschonoskii Maxim., Vaccinium hirtum var. koreanum (Nakai) Kitam., Primula modesta var. hannasanensis T.Yamaz., Trientalis europaea var. arctica (Fisch.) Ledeb., Thymus quinquecostatus Celak., Parasenecio firmus (Kom.) Y.L.Chen, and Lilium cernuum Kom. These species are expected to be particularly vulnerable to the effects of global warming, since they were confirmed to have a very narrow vertical distribution range. Moreover, although the following species are not included in the list of plants threatened by climate change, it is assumed that the endemic species that grow at the summit, and Grade V floristics special plants, such as Pedicularis hallaisanensis Hurus., Allium thunbergii var. deltoides (S.O.Yu, S.Lee & W.Lee) H.J.Choi & B.U.Oh, Heloniopsis tubiflora Fuse, N.S.Lee & M.N. Tamura, Aletris glabra Bureau & Franch, and Gymnadenia cucullata (L.) Rich., will also be extremely vulnerable to climate change. Therefore, we believe that measures for the conservation of these species are urgently needed, and also that the definition of species threatened by climate change should be broadened to include more objective and valid taxa through the long-term monitoring of species distributed around the summit area.

We investigated the area around four moors from May 2009 to June 2010 for plant diversity in Moojechineup, officially designated as the Ramsar wetland. The vascular plants of Moojechineup at Mt. Jeongjok were recorded as total 149 taxa, 55 families, 105 genera, 128 species, 1 subspecies, 16 varieties, and 4 forms. Rare plants were observed 7 taxa (Eriophorum gracile Koch, Drosera rotundifolia L., Iris ensata var. spontanea (Makino) Nakai, Kobresia bellardii (All.) Degl, Utricularia bifida L., Utricularia racemosa Wall., Utricularia yakusimensis Masam.). Korean endemic plants were 1 taxon, floristics special plants were 19 taxa, and naturalized plants were 3 taxa. Phytogeographical and evolutionarily, Eriophorum gracile is an important species; hence, further studies are needed to conserve it. Moojechineup is similar to the Shinbulsan wetland in terms of wetland plants (hydrophytes). Moojechineup's flora changes are in process slowly compared to earlier work; thus, continuing interest and appropriate measures should be encouraged.

The vascular plants recorded from the 11 sites of coastal sand dune in North Gyeongsang Province are as follows: 204 taxa, 2 hybrids, 1 form, 22 varieties, 1 subspecies, 178 species, 132 genera, 43 families. These areas also present rare plant (Glehnia littoralis); 20 taxa, 20 species, 20 genera, and 15 families of floristics special plants; 46 taxa, 2 variety, 44 species, 30 genera, and 12 families of naturalized plants. The ratio of urbanization and naturalized index is 16.14% and 22.55% respectively. Life form spectrum is Th-$R_5-D_4$-e type. The number of species recorded from the coastal sand dune in Hujeong area turned out to be the highest (44.6%), and the coastal sand dune in Heseo area showed the highest naturalized index (31.58%).

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. Gray, class V species (1 taxon) were Utricularia vulgaris var. japonica (Makino) Tamura. The naturalized plants were identified a total of 52 taxa; 17 families, 44 genera, 51 species, 1 form; Solanum carolinense L., Phytolacca americana L. and Oenothera odorata Jacq., etc. Among them the ecosystem disturbance wild animals·plants was identified as Solanum carolinense L. Hypochoeris radicata L. and Solidago altissima L. The study suggests that these areas require management such as physical remove of this ecosystem disturbance field plants.
