This study surveyed the vascular flora present in abandoned paddy field type of 237 forest wetlands in Korea to provide baseline data for conservation, management, and monitoring and to support preparation for damage and climate change. The study period was from April 2015 to November 2021. The vascular flora of 237 forest wetlands by abandoned paddy field type were identified to consist of 128 families, 510 genera, 1,022 species, 27 subspecies, 87 varieties, 10 forma, and 1,146 taxa. 4 taxa were identified as grade II endangered wild plants, 185 taxa were identified as northern lineage plants of the Korean Peninsula, 43 taxa were endemic to the Korean Peninsula, and 58 taxa were rare plants as designated by the Korea Forest Service. Further, 296 taxa were floristic target plants and there were 86 taxa of invasive alien plants. According to wetland preference, 79 taxa (6.9%) were obligate wetland plants, 103 taxa (9.0%) were facultative wetland plants, and 61 (5.3%) taxa were facultative plants. Additionally, 66 taxa (5.8%) were facultative upland plants, and 837 taxa (73.0%) were obligate upland plants.

The flora of Mt. Kum.lung(80 lm) was Investigated to compare the flora of Mt. Hwang-Ryung, Mt. Cheon-Hwang, Mt. Chulseo. The vascular plants, collected from March 1995 to Oct., 1996, were consisted of a total 564 taxa: 103 families, 312 genera, 493 species, 1 subspecies. 66 varieties and 4 forms. The Korean endemic plants of this area were 11 taxa, the alplan and endangered plants were 29 taxa, the special wild plants designatlrlg by Enoronmental Agency were 2 taxa and the alpian plants were 18 taxa. Because many plants, being necessary to conserve, are distributed Kumjung, but if development is indespensable. destruction of natural ecosystem must be minimized.

Sonjook island is located Samsan-myeon, Yeosu-si, Jeollanam-do. All of field information was collected from January 2001 to November 2002. The vascular plants recorded as total 584 taxa, 5 forms, 60 varieties, 519 species, 365 geneta, 113 families. Sonjook islands shows the typical vegetations including the lower area of temperate region of Korean peninsula and evergreen broad-leaved forests, Pinus thunbergii forest. The Korean endemic plants were recorded as 13 taxa (5 variety, 8 species, 10 genera, 10 families), 4 taxa as rare and endangered plants (Psilotum nudum (L.) Griseb., Milletia japoniea A. Gray, Arisaema negishii Makino, Sarcanthus scolopendrifolius Makino). The naturalized plants were 23 taxa (20 genera, 9 families, 8.2％ among the total naturalized plants in Korea. This area is ecologically important place that Korea endemic plant, rare and endangered plants ranges much than area. On the one hand, threat from degraded by environmental pollution that share of naturalized plant rises gradually augment. Strong conservation policy and development control should be considered.

Distribution of vascular plants in Yangyang-gun were investigated 12 times from Apr. to Sept., 2008. In the result of survey, the flora of this area consist of 412 taxa totally; 89 families, 259 genera, 366 species, 5 subspecies, 37 varieties and 4 forms. There were remarkable plants such as 11 taxa of Korean endemic plants, 58 taxa of specific plants which were designated by the Ministry of Environment, 2 taxa of endangered plants of Ministry of Environment, 7 taxa of rare, endangered plants of Korea Forest Service and 28 taxa of afforestation plants and 296 taxa of useful plants. Furthermore, 36 taxa of naturalized plants (8.74%) were also observed in this area. Vegetation of investigated area was conserved well. However, vegetation has been destroyed rapidly due to construction of commercial complex for human recreation such as condominiums and stores. Therefore, it is need to efficient management of the water quality and vegetation by conservation strategies from huge visitors.

This study was conducted to investigate the vascular flora of Masan, located in Goseong-gun, Gangwon-do, and to comprehend the distribution of remarkable plants such as rare and Korea endemic plants and invasive alien plants. The survey was carried out the distribution of vascular plants 11 times per season from 2010 to 2018. A total of 619 taxa in 93 families, 328 genera, 529 species, 6 subspecies, 78 varieties and 6 forms were identified on mt. Masan. Among them, Korean endemic plants are 21 taxa including Saussurea diamantica Nakai and are plants designated by the Korea Forest Service are 20 taxa counting Saxifraga octopetala Nakai. Invasive alien plants were classified a total of 35 taxa inclusive of Trifolium pratense L. (WS), Aster pilosus Willd. (SS), Coreopsis lanceolata L. (SR), Rumex obtusifolius L. (SC) and Lindernia dubia (L.) Pennell (CS). The naturalization rate was 5% and the urbanization index was 10.0%, respectively. Although this study identified the diverse distribution of major plants such as rare and endemic plants around Masan, it was confirmed that invasive alien plants, which pose a great threat to forest biodiversity conservation and promotion, spread and distributed in a specific section Therefore, it is urgent to establish a conservation strategy and countermeasures.

This study aims to investigate the flora of Mt. Cheonma (Namyangju-si, Gyeonggi-do, Korea), including Korean endemic, rare and endangered plants. To support the biodiversity and usefulness of this investigation, we checked the red list plants, floristic regional indicator plants, climate change adaptation target plants and naturalized plants, and compared composition of plant species in Mt. Cheonma with nearby mountains. Totally, we performed 22 field investigations from April 2012 to October 2014. The number of vascular plants in this region is 433 taxa and comprised of 94 families, 266 genera, 378 species, 2 subspecies, 46 varieties, and 7 forms. Among them, there are 13 endemic plants designated by Korean Forest Service, whereas only 10 taxa are endemic species by Korean Ministry of Environment (KME). According to the IUCN criteria, there are 12 rare and endangered plants composed of 9 Least Concerned (LC), 2 Vulnerable species (VU), and one Endangered species (EN) found by Korea National Arboretum (KNA). Meanwhile, 8 taxa including 7 Least Concerned (LC) were found in Red List of KME. The floristic regional indicator plants designated by KME were 49 taxa. In addition, there are 14 taxa in The Adaptable to Climate Change Plant List designated by KNA, while only 19 taxa are naturalized plants. Generally, there are 190 common taxa in Gwangju Mountains area, and only 51 taxa are distributed in Mt. Cheonma.

And in the results of survey on resource plants among 400 taxa, we confirmed 162 taxa of ornamental plants(40.5％), 250 taxa of edible plants(62.5 ％), 257 taxa of medicinal plants(64.3％) and 167 taxa of the others(41.8 ％). The six taxa were recorded in the surveyed sites as the Korean endemic plants; Hytomecon hylomeconoides, Filipendula palmata var. glabra, Ajuga spectabilis, Weigela subsessilis, Cirsium setidens and Saussurea seoulensis.

We performed the floristic study of Carpathian mountains in Ukraine from April 2008 till October 2009. We designated eight important areas to investigate in Ukraine Carpathians including Svydovets, Chornohora, Kuziy-Trybushany, Maramorosh, Uholka-Shyrokyi Luh, Narcissi Valley, Chorna Hora, and Yulivska Hora. The total numbers of vascular plants in investigated area were 1,349 speices from 502 genera and 112 families. The endemic species to Carpathians numbered to 65 from 49 genera belonging to 24 families, and it was corresponded to 4.8% of the 1,349 vascular species. We prepared the list of vascular plants with compiling database on useful plants. Ukraine Carpathians endemic species could be applied as high value products in research and practice. Moreover, the flora of Carpathian mountains which is distributed in five nations in eastern Europe and famous for Primeval Beech Forests (Fagus sylvatica), is useful to compare the floristic study with Korean flora.

This study aimed to elucidate the distribution of vascular plants on the Deok mountain in Ganghwa-gun, Korea. The results of 10 field surveys from March to October of 2019 identified 532 taxa in total, representing 482 species, 9 subspecies, 39 varieties, 1 form, and 1 hybrid in 318 genera and 105 families. The plant formation of Deok mountain is the deciduous broad-leaved and conifer mixed forest, which is the common one in the middle region of the Korean Peninsula. Among them, 301 taxa were newly recorded in this study, 7 taxa were endemic plants to Korea, 3 taxa were red list plants. The floristic target plants amounted to 41 taxa, specifically 1 taxon of grade V, 2 taxa of grade IV, 7 taxa of grade III, 9 taxa of grade II, and 22 taxa of grade I. Alien plants were recorded a total of 73 taxa with a naturalized index of 13.7%, the urbanization index was calculated to be 11.8% and 4 taxa were ecosystem disturbance plants.
