This study was carried out as basic data for the conservation and management of plant diversity in the Gudeuljang paddy fields stone retaining wall of Cheongsan-island by identifying the characteristics of vascular plants targeting Gudeuljang paddy fields stone retaining wall in Cheongsan-island. The total vascular plants of the Gudeuljang paddy fields stone retaining wall in Cheongsan-island have been identified with a total of 184 taxa of 60 families, 142 genera, 170 species, 5 subspecies, 9 varieties. Rare plants were 1 taxa, Korea endemic plants were 2 taxa, floristic regional indicator plants were 28 taxa, rock vegetation was 20 taxa, and invasive alien plants were 25 taxa. Among them, Selliguea hastata (Thunb.) Fraser-Jenk., a rare plants, has been identified as a small number of individuals in the Gudeuljang paddy fields stone retaining wall in Buheung-ri and Cheonggye-ri, but it is necessary to conservation the habitat because there is a concern that the species and population will decrease due to damage and neglect of the Gudeuljang paddy fields stone retaining wall.

This study was investigated to find out the distribution of flora and remarkable plants and factors and management measures for influx of wild disturbed plants in the Damyang area of Mudeungsan National Park. The field survey was carried out 8 times from May 2019 to October 2020. First of all, in the Damyang area of Mudeungsan National Park, a total of 603 taxa in 107 families, 349 genera, 531 species, 57 varieties, 5 subspecies and 10 forms. This result was found to be about 12.33% of the total 4,881 taxa of vascular plants in Korea. In addition, Rare plants were classified as 15 taxa. Floristic special and Korean endemic plants were identified as 85 taxa and 13 taxa, respectively. Lastly, the naturalized plants that appeared in the Damyang area of Mudeungsan National Park were observed in 45 taxa with 45 species of 16 families and 36 genera. Moreover the naturalization rate was 7.46% and the urbanization index was calculated to be 14.01%. The wild disturbed plants were found in a total of 4 taxa. Especially, a sheep sorrel(Rumex acetosella) was focused on managing for physica and biological control at Sinseondae Eoksaepyungjeon.

This study was carried out to illiminate the diversity of vascular plants by making list of rheophyte and hydorphyte plants at Yugu stream. This study was conducted from Aug., 2009 to Sept. 2010 at 7 points. Based on the voucher specimens, vascular plants from investigated areas were 88 families 229 genera 290 species 3 subspecies 30 varieties 5 forms, totally 328 taxa. Korean endemic plants were 3 species such as Forsythia koreana (Rehder) Nakai (planted) and Paulownia coreana Uyeki (planted), and Weigela subsessilis (Nakai) L.H. Bailey. The rare and endangered plants were designated by Korea Forest Service were 4 taxa, such as Penthorum chinense Pursh, Acorus calamus L., Lilium callosum Siebold & Zucc. and Iris ensata var. spontanea (Makino) Nakai. Floristic special plants were totally 26 taxa, which were grade V of 2 taxa, grade IV of 2 taxa and grade III of 9 taxa. Naturalized plants were 27 taxa, that was 8.3% of whole discovered vascular plants in this area. Even naturalized plants has not influence on the vegetation of Yugu stream. Since village was composed along the stream and the roads and banks were linked, naturalized plants were flowed continuously into this region. So, strategy of the conservation for this region should be designed. Based on flora, 3 types of group were discriminated such as main stream type (4 points), branch stream type (2 points) and reservior type (1 point). Each group has difference in composition of plants.

We investigated the flora of Mudeung-san (Mt.) located in Gwangju-gwangyeoksi, Hwasun-gun and Damyang-gun and discussed the vascular plants found there. 22 days separate fild trips were completed from March of 2009 to November 2011. As a result, we identified the distribution of 816 taxa in Mudeung-san (Mt.), comprising 123 families, 441 genera, 668 species, 5 subspecies, 121 varieties and 18 forms. There are a total 111 taxa of floristic regional indicator plants. The floristic regional indicator plants are as follows; nine taxa of level V such as Gastrodia elata Blume, six taxa of level IV such as Hylomecon hylomeconoides T. Lee, 21 taxa of level III such as Stewartia korena Nakai, 18 taxa of level II, and 66 taxa of level I. In addition, two critically endangered species (CR), Galeola septentrionalis Rchb.f. and Paeonia obovata Maxim., two endangered species (EN), Dryopteris cycadina (Franch. & Sav.) C.Chr. and Jeffersonia dubia Benth., and eight vulnerable species (VU), such as Lilium callosum Siebold & Zucc, were found in the investigated area. Also, 14 endermic plants of Korea, such as Salix koriyanagi Kimura and Aconitium chiisanense Nakai, were found.

This study was carried out to investigate the vascular plants of Mt. Choejeong in Gachang-myeon, Daegu. From March 2017 to October 2018, a total of 22 studies were conducted. The vascular plants surveyed were grouped into 560 taxa, including 104 families, 297 genera, 495 species, 4 subspecies, 51 varieties and 10 forma. Endemic plants 15 taxa, Rare plants 5 taxa, Red list plants 5 taxa, Floristic regional indicator plants 54 taxa, Naturalized plants 36 taxa were recorded. Among surveyed 560 taxa, edible, medicinal, ornamental, timber, pasturing, industrial and fiber plants included 246 taxa (29.2%), 228 taxa (27.1%), 164 taxa (19.5%), 61 taxa (7.2%), 13 taxa (1.5%), and 8 taxa (0.9%). And because people are coming and going more frequently than in the past, this will result in more frequent influx of naturalized plants and a threat to the habitat of the plants that are currently growing.

The flora of vascular plants in the Gibaeksan Mt. County Park and its neighboring mountains, located at the boundary between Geochang-gun and Hamyang-gun in Gyeongsangnam-do province in Korea, were surveyed for a total 46 times from April to September of 2011, in July of 2012, and from April of 2015 to August of 2018. The result of this survey revealed 659 taxa composed of 107 families, 346 genera, 583 species, 14 subspecies, 46 varieties and 6 forms. Among them, 25 taxa were endemic plants to Korea, and 18 taxa were rare and endangered plants of Korea. The floristic regional indicator plants including cultivated plants were 5 taxa of grade V, 5 taxa of grade IV, 29 taxa of grade III, 30 taxa of grade II and 38 taxa of grade I. Forty-three taxa of alien plants were found in this area. In addition, 500 taxa out of a total of 649 taxa were categorized by usage into eight groups, including among others an edible group containing 257 taxa, a medicinal group containing 206, a pasturing group containing 220, and an ornamental group containing 84, with some taxa belonging to more than one group.

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.
