Vascular plants of Yeonhwasan Mt., located in Taebaek-si, Gangwon-do, were investigated. Field surveys were conducted fourteen times between April and September of 2022. A total of 505 taxa were found consisting of 87 families, 282 genera, 441 species, 15 subspecies, 41 varieties, and 8 forma. Among them, the endemic plants of Korea were 22 taxa. The number of threatened and near threatened Red List plants designated by the Korean National Arboretum was four, comprising each one of critically endangered (CN), endangered (EN), vulnerable (VU), and near threatened (NT) species. The number of floristic target plants designated by the Ministry of Environment was 102, including one taxon of level V, 9 taxa of level IV, and 34 taxa of level III. Invasive alien plants were 34 taxa, and three taxa were ecosystem disturbance plants. The urbanization index of investigated site was 12.8%, and the naturalization index was 6.7%. To wisely manage Yeonhwasan, measures for preserving biodiversity and preventing invasive plants are needed.

This study aimed to obtain fundamental data for demonstrating biodiversity of vegetation of East Asian alder (Alnus japonica) Forest Wetland of Heonilleung Royal Tombs. A total of 166 vascular plants (159 species, three subspecies, three varieties, and one cultivar) belonging to 132 genera and 59 families were found, accounting for 8.3% of 1,996 vascular plant species found in Seoul. Therophyte was the most common life-form of plants in Heonilleung Wetland. As for rare plant species, one Least Concern (LC) species was found. There were 15 floristic regional indicator species in the research area. Three of them belonged to floristic grades III and IV. This indicates that their habitats are discontinuous and isolated to some degree. Nineteen invasive alien plant species were found, most of which were introduced from North America after the year 1964 with a spread rate of V (widespread, WS).

Hwangmaesan Mt. (1,108 m) is rich in forest biodiversity and is a part of the Sobaek mountain range located in Hapcheon-gun, Gyeongsang-do in Korea. Unfortunately, the biodiversity and ecosystem integrity of Hwangmaesan Mt. have recently been threatened by heavy human disturbances. We conducted thirteen field surveys between March and October of 2019 to investigate the vascular flora in Hwangmaesan Mt. Through this extensive survey, we found 628 taxa consisting of 106 families, 349 genera, 554 species, 16 subspecies, 48 varieties, and 10 forma. Based on a comparative analysis between the present findings and former flora reports, our results showed an increase by 28 percent in the number of taxa observed. Of the 628 taxa, dicotyledons made up the largest group (477 taxa, 76.0%) followed by monocotyledons (120 taxa, 19.1%). Endemic plants consisted of 16 taxa, with rare plants designated by the Korea Forest Service numbering 14 taxa. Ten taxa were listed on the Red list by the Ministry of the Environment. The floristic target species designated by the Ministry of the Environment numbered 75 taxa, whereas there were 42 taxa of invasive plants.

To identify the flora of the vascular plants in the Anmyeon Island, field surveys were conducted from June, 2015 to August, 2016. Based on the collected specimens, the vascular plants of the Anmyeon Island were summarized as 717 taxa: 119 families, 400 genera, 632 species, 5 subspecies, 73 varieties and 7 formas. Among the 717 identified taxa, 17 rare plants designated by the Koren Forest Service according to the IUCN valuation species were described: 3 taxa of critically endangered species (CR), 1 taxa of endangered species (EN), 6 taxa of least concerned species (LC), 7 taxa of vulnerable species (VU). 99 taxa of floristic regional indicator plants specially designated by Ministry of Environment also were identified. In addition, 6 Korean endemic species such as Forsythia koreana Nakai and Hemerocallis taeanensis S.S.Kang & M.G.Chung, and 91 naturalized plants such as Rumex acetocella L., Amaranthus lividus L. and Diodia teres Walter etc. were described.

We investigated vascular plants of Aphaedo Island in Shinan-gun, Jeollanam-do, Korea. By referring to voucher specimens collected over the course of 28 days from May of 2011 to March of 2016, a total of 451 taxa were identified and grouped into 102 families, 294 genera, 413 species, 6 subspecies, 30 varieties, and 2 forms, of which 9 taxa were classified as endangered or rare, including Albizia kalkora, Salomonia oblongifolia, and Centranthera cochinchinensis var. lutea. A total of 59 taxa were identified as regional indicator plants. Six taxa were endemic to Korea, including Hepatica insularis, Indigofera koreana, and Lespedeza maritima. Three taxa (Rumex acetosella, Aster pilosus, and Hypochaeris radicata) among 52 naturalized taxa were ecosystem-disturbing plants as designated by the Ministry of the Environment. The results of preceding floristic research before and after the inauguration of the Aphaedaegyo (bridge) were used to analyze changes in the number of naturalized species on Aphaedo Island.

Floristic study can help to understand the current status of species diversity, evaluate and predict distribution changes of plants based on the specimens, and record the climate environment and biodiversity of the Korean Peninsula. Boraebong is an area that has plant resources of conservation value, but there is concern about artificial interference through trail and forest road. Therefore, this study aims to report the vascular plants of Boraebong based on voucher specimens and photos and to use them as baseline data to conserve biodiversity of Boraebong. Also, it will be useful to prevent additional influx of invasive species through comparison with previous studies. The investigation was carried out 11 times from April to September in 2022 and confirmed a total of 455 taxa including 87 families, 269 genera, 401 species, 13 subspecies, 35 varieties, 6 forms. In addition, we confirmed the 4 taxa of red list plants (EN 2 taxa, NT 2 taxa), 18 taxa of Korean endemic plants, and 102 taxa of floristic target species (V degree 1 taxon, IV degree 16 taxa, III degree 31 taxa, II degree 31 taxa, I degree 23 taxa). Furthermore, alien plants 17 taxa, invasive species 2 taxa, useful plants 439 taxa were confirmed in Boraebong. As the results of comparison with previous studies, 98 total taxa including 38 families, 76 genera, 86 species, 1 subspecies, 8 varieties, 3 forms were newly identified in this study.
