Mt. Deoktaesan(1,113 m) is located in Jinan-gun Baekun-myon and Jangsu-gun Chunchun-myon. Investigated area was decided to include Mt. Deoktaesan, Mt. Seongaksan and its neighbor area, and this study was conducted from March to October, 2015 in 12 days. Based on the voucher, vascular plants in Mt. Deoktaesan were 108 families 341 genera 525 species 4 subspecies 64 varieties 14 forms, totally 607 taxa, which is 12.4% of total Korean flora. Korean endemic plants were 15 species. Among these species, Populus tomentiglandulosa T.B.Lee, Campanula takesimana Nakai and Forsythia koreana (Rehder) Nakai are verified as planted species. Rare and endangered plants of designated by Korea Forest Service were 10 taxa, such as Peucedanum hakuunense Nakai, Paeonia japonica (Makino) Miyabe & Takeda, Koelreuteria paniculata Laxmann, Eranthis stellata Maxim., Eranthis stellata Maxim., Viola albida Palib., Chionanthus retusus Lindl. & Paxton, Campanula takesimana Nakai, Tricyrtis macropoda Miq. and Iris ensata var. spontanea (Makino) Nakai, respectively. Phytogeographical special plants were totally 41 taxa, which were grade 17 taxa of garde I, 12 taxa of grade II, 12 taxa of grade III, 8 taxa of grade IV, and 1 taxon of grade V.

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.

This study was carried out to illuminate the flora of vascular plants of islands at Chungnam. This study was conducted from March to November, 2010. Based on the voucher, vascular plants of in investigated islands were 105 families 326 genera 454 species 4 subspecies 45 varieties 9 forms, totally 512 taxa. Korean endemic plants were 6 species such as Aster koraiensis, Salix koriyanagi, Indigofera koreana, Hemerocallis taeanensis, Hepatica insularis, Philadelphus schrenckii, rare and endangered plants of designated by Korea Forest Service were 4 taxa, such as Magnolia kobus (planted), Koelreuteria paniculata, Berchemia racemosa var. magna, Glehnia littoralis respectively. Phytogeographical special plants were totally 69 taxa, which were grade I of 50 taxa, grade II of 1 axon, grade III of 11 taxa, grade IV of 4 taxa, and grade V of 3 taxa. 14 southern plants and 4 northern plant by criterion from climate change study were found in this area. Naturalized plants were 17 families 46 taxa, that was 9.1% of total vascular plants in this area. Even naturalized plants has not influence on the islands vegetation. However, regular passenger ferry between islands and increasing of visiter will be affecting vegetation.

The purpose of this study was to investigate the distribution of vascular plants in Mt. Daedeukbong. The study is significant because surveying the flora of old-growth forest in Mt. Daedeukbong is a way of understanding what kind of plant species exist in DMZ as the geographical characteristics of Mt. Daedeukbong adjacent to Korean DMZ have the role of a buffer zone connecting the DMZ and its southern region. We collected the vascular plants 7 times from May 2015 to May 2017 and found a total of 393 taxa consisting of 84 families, 245 genera, 341 species, 4 subspecies, 43 varieties and 5 forms. The observed rare plant species as designated by Korea Forest Service were 8 taxa, and the endemic species were 6 taxa. 44 taxa were listed as specific plant species based on phytogeographical in the investigated area. 23 taxa were recorded as naturalized plants, and the naturalized rate and urban index were 5.3% and 8.7%, respectively.
