The flora of vascular plants in the Geumgang area (Mt. Guryongsan, Mt. Jeonwolsan, Mt. Samasan, Mt. Yongmeorisan and Mt. Hamrasan) was investigated to suggest strategies for conservation. This study was performed from May 2007 to April 2008, with total 17 times. The Korean endemic species, legally protected species and species to threaten domestic ecosystem species to threaten were grasped on this study. 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. The degree of destroy of forest vegetation and reduction of plant diversity in the midstream of Geumgang were in proceeding by construction of multifunctional administrative city and cultivation. It is needed to set up strategies for conservation forest vegetation in this study area.

Gwangdeoksan Mountain (699.3 m) is the highest border mountain between the two cities of Chungcheongnamdo Province, Cheonan and Asan, Korea. In this study, we investigated the flora of Gwangdeoksan Mt. from April of 2015 to October of 2017. Through 20 independent field investigations, we identified and tallied a total of 428 species, 9 subspecies, 30 varieties, and a forma in 287 genera and 97 families. Of a total of 468 taxa, 128 taxa in 112 genera and 58 families were found to be Korean endemic species (7 taxa), floristic regional indicator species (45 taxa), rare or endangered species (3 taxa), species subject to the approval of outbound transfer (73 taxa), and alien or ecosystem disturbing species (32 taxa). The flora of Gwangdeoksan Mt. can be divided into four distinct floristic subregions, with higher diversity in the north-facing subregion. The complex flora of Gwangdeoksan Mt., emerging at the edge of two floristic regions of the Korean peninsula, may represent a significant conservation priority and a topic for future ecological and geographical studies.

This study was carried out to investigate the vascular flora of Mt. Munsu. The vascular plants collected in 13 times(from Mar. to Oct. 2009) were identified as 511 taxa in total, including 113 families, 332 genera, 445 species, 5 subspecies, 46 varieties, 5 forms. Among them, 6 taxa of the Korea Forest Service-designated rare & endangered plants and the Korean endemic plants were identified as 2 taxa. Based on the list of approved for delivering overseas of plants, 6 taxa were recorded in the investigated area. The Ministry of Environment-designated plants, which should be protected by the wildlife protection law, were identified as 2 taxa and 39 taxa of specially designated plants by the Ministry of Environment. The naturalized plants were identified as 53 taxa, and their naturalization ratio and urban index were found to be 10,3%, and 18.5% respectively. There existed many kinds of plants resources having conservational value like Ranunculus trichophyllus var. kadzusensis, Jeffersonia dubia etc, in this area, but there remains a fear of nature destruction's acceleration due to indiscriminate human development and access of a lot of visitors, so it is judged that there should be a management plan, such as a limit on the number of visitors or rest-year-system for restoration of nature.

This study was investigated on biodiversity and life forms of plants distributed in 28 wetlands on Jeju city, in order to apply wetlands to nature exploration sites for environmental education. The 131 kinds of the plants were found on 28 wetlands. The plant biodiversity was relatively high in Ban pond, Jeongmool, Mosanimool, Dolgaegi pond, Woot pond, and etc. The $5{\sim}6$ life forms of plants, relatively high in variousness to other wet lands, were distributed in Mosanimool, Dolgaegi pond, Woot pond, and Yeonhoa pond as well as Jeongmool and Yongsoo reservoir. The 71 kinds, which correspond to 54.2% of plants observed in this study, were identified as hydrophytes. The $4{\sim}5$ forms of hydrophytes were distributed on 23 wetlands, including Jeongmool, Mosanimool, Yongsoo reservoir, Ban pond, Dolgaegi pond, and etc. In conclusion, 5 wetlands such as Jeongmool, Yongsoo reservoir, Dolgaegi pond, Mosanimool and Woot pond were high in variousness of plant life forms as well as biodiversity of plants. These results suggest that 5 wetlands above could be applied as nature exploration sites. In addition, Korean rare and endangered plants such as Isoetes japonica, Nymphoides coreana, Utricularia japonica and Sparganium stoloniferum in this study need to be conserved.

The district of Ganghwa-gun in the western coast (Seohae) of the Korea is consisted of several islands, Ganghwa-do, Seokmo-do, Gyodong-do, Jumun-do, Boreum-do, Seogeom-do and Donggeom-do. Since several islands of them were connected to mainland of Korea by bridges, the islands attract a lot of tourists from Seoul, Incheon and Gyeonggi-do areas. Construction of new roads, pensions, resort areas and restaurants provided economical benefits to local residents while natural vegetation of these islands has deteriorated continuously. Before biodiversity of vascular plants in these regions is damaged seriously by human impacts, it is needed to conserve original vegetation of the islands for restoration and monitoring in the future. Therefore, the primary purpose of the study is to clarify the flora of Donggeom-do, belonging to Ganghwa-gun. From the 15 times of field trips to the island, we have collected a number of vascular plants, 512 taxa in total, including 110 families, 329 genera, 449 species, six subspecies, 52 varieties, four forms and one hybrid. Of 512 taxa investigated, we have identified 12 taxa to be endemic to Korea. Six taxa were endangered or rare species which were designated by the Ministry of Environment and Korea Forest Service, respectively. 25 taxa were recognized as floristic regional indicator species designated specially by the Ministry of Environment. Seven species have shown their northern or southern distributional limit ranges, and 29 taxa were recognized as halophytes. The naturalized plants were identified as 55 taxa, and their naturalization ratio was 10.7%.

Tonggo-san(1066.5m) is located at 36° 53' 00" - 36" 55' 00" in latitude, at 129° 10' 30" - 129° 13' 00" in longitude and on Seo-myeon, Uljin-gun and Subi-myeon, Yeongyang-gun in Gyeongsangbuk-do. Tonggo-san shows the typical vegetation patterns including the middle area of temperate region of Korea represented by the secondary forests of Quercus mongolica and Q. dentata. There was no detailed result on the flora and vegetation of Tonggo-san until now. Therefore, we tried to discuss on the distribution and availability of vascular plants including economical plants. Also, we could discuss the especialized plants and their distributions according to the criteria by the Ministry of Environment. The results of plant collection and their investigation from April in 2001 to November in 2001 are as follows : The vascular plants consist of total 565 taxa; 17 forms, 82 varieties, 466 species, 297 genera, 94 families,37 orders, 4 classes, 2 subphyla. In this area, there were a lot of useful economic plants such as 232 taxa(41%) of edible source, 222 taxa(39％) of forage source, 183 taxa(32%) of medicinal source, and 72 taxa(12%) of ornamental source, 15 taxa(2.6%) timber source, 7 taxa(1.2%) industrial raw material source respectively. Among them, the Korean endemic plants were 22 taxa(3.9％ among total 565 taxa); 1 forms, 2 varieties, 19 species, 22 genera, 16 families. And rare and endangered plants was 1 taxa; Astragatus membranaceus. Also, the naturalized plants were 19 taxa(3.4% among total 565 taxa and 10.4% among the total naturalized plants in Korea).
