This study was conducted to study the vascular plants of Balbaeksan, located on the border between Gyeongsan-si and Cheongdo-gun, Gyeongsangbuk-do. It was performed 13 times from September 2020 to November 2021, and the investigated vascular plants were identified as a total of 93 families, 302 genera, 485 species, 10 subspecies, 40 varieties, 13 varieties, and 545 taxa. Endemic plants were investigated in 18 taxa, 9 taxa of rare plants; Vulnerable (VU) 5 taxa, Least concerned (LC) 3 taxa, Data Deficient (DD) 1 taxa, Red List plants 5 taxa; 3 taxa of least concerned (LC), 2 taxa of Not Evaluated (NE), 183 taxa of biological resources subject to export approval, 78 taxa of specific taxonomy; There were 9 taxa of grade IV, 20 taxa of grade III, 20 taxa of grade II, and 28 taxa of grade I. 4 taxa of plants subject to climate change adaptation; 2 taxa of endemic plants, 1 taxa of southern plants, 1 taxa of northern plants, 4 taxa of climate change biomarker species, 2 taxa of candidate species of climate change biomarker, 65 taxa of exotic plants, and 3 taxa of ecosystem disturbance species. Plants 235 taxa (43.1%), medicinal plants 257 taxa (47.2%), ornamental plants 148 taxa (27.2%), woody plants 54 taxa (9.9%), herbaceous plants 37 taxa (6.8%), industrial plants 15 Taxa (2.8%), 11 taxa (2.0%) of fiber-bearing plants, and plants of unknown use were identified as 73 taxa (13.4%). The flora of Mt. Balbaek was investigated for the first time, and plants to be preserved in order to secure useful plant resources and biological sovereignty were identified. So continuous monitoring is necessary to prevent the introduction of foreign plants that may be caused by the recent increase in the number of people coming and going.

In this study, we conducted a flora survey at Mt.Bakdal (363m) and Mt. Myeongbong (245.3m) in Paju-si, Gyeonggi-do. A total of 405 taxa, including 2 forms, 32 varieties, 8 subspecies, 363 species, 261 genera, and 87 families, were surveyed in the two mountain areas. The ferns were identified as 12 taxa from 6 families, the gymnosperms as 6 taxa from 2 families, the dicotyledonous plants as 290 taxa from 70 families, and the monocotyledonous plants as 97 taxa from 9 families. The remarkable plants included 8 taxa of the Korean endemic plants, which were Populus tomentiglandulosa, Salix koriyanagi, Clematis brachyura, Viola seoulensis, Forsythia koreana, Paulownia coreana, Weigela subsessilis, and Hemerocallis hakuunensis, and 3 taxa of the rare and endangered plants as designated by the Korea Forest Service, including Tylophora floribunda as Vulnerable (VU) species, and Viola albida and Chionanthus retusus as Least Concern (LC) species. The invasive alien plants were 35 taxa, including Rumex crispus, Phytolacca americana, Cerastium glomeratum, Chenopodium album, Chenopodium ficifolium, Lepidium virginicum, Amorpha fruticosa, Robinia pseudoacacia, and Trifolium repens, accounting for 8.5 percent of the 405 taxa of the surveyed plants. We intend to further identify plants through the studies on unsurveyed areas in the western part of the DMZ, identify the native habitats of rare and specialty plants, and use them as basic data for managing ecosystem-disturbing plants.

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.

This study aimed to investigate the flora of Jinjosan Mt. (Uljin-gun, Gyeongsangbuk-do). The vascular plants were surveyed 9 times between March 2019 and April 2020. The results of this survey revealed a total of 414 taxa comprising of 87 families, 274 genera, 365 species, 12 subspecies, 32 varieties, and 5 forms. Among them, 9 taxa were Korean endemic plants and 5 taxa were rare plants of Korea. In addition, the specific plants by floristic region were 66 taxa including 1 taxon of grade IV, 18 taxa of grade III, 24 taxa of grade II, and 23 taxa of grade I. Additionally, eight taxa were classified as plants adaptable to climate change. Thirty-one taxa were of alien plants and three taxa were of ecosystem disturbance species, which were also investigated. The percentage of naturalized plants species and the urbanization index were estimated to be 7.5% and 5.0%, respectively. Our results provide basic data on vascular plants flora, and will guide the conservation processes of plant resources such as plant diversity and distributional changes in Jinjosan Mt.

This study was conducted to investigate the vertical distribution and vascular plants in the Gakho mountain. Form the results of three field surveys from May 2022 to September 2022, a total of 478 total taxa, representing 426 species, 11 subspecies, 35 varieties, four forms, and two hybrids were identified, which were categorized in 282 genera and 94 families. We identified the elevational distribution ranges of 398 taxa of vascular plants. Among them, 19 taxa were endemic to Korea, one taxon was identified as a rare plant. The floristic target plants amounted to 72 taxa, specifically two taxa of grade V, two taxa of grade IV, 16 taxa of grade III, 27 taxa of grade II, and 25 taxa of grade I. Further, 71 taxa were identified as northern lineage plants. A total of 19 taxa of alien plants were identified, with a Naturalized Index of 4.0%, an Urbanization Index of 6.6%, and three plants that disturbed the ecosystem. The result of analyzing the pattern of species richness showed a reversed hump shape with minimum richness at mid-high elevation. A cluster analysis showed a high degree of similarity between adjacent elevation sections that are geographically adjacent with similar habitat environments. Warmth index in the Gakho mountain ranged from 57.2℃·month to 84.2℃·month. Our results provide basic data on vascular plants and valuable information on elevational distribution ranges of current plant species in the Gakho mountain, which could serve as a baseline for comparison of the shifts in elevation under future climate change.
