This study was carried out to investigate the flora of the Hanbando wetland (Yeongwol-gun, Gangwon-do) from April 2019 to May 2020. Vascular plants were grouped into 508 taxa, comprising 93 families, 309 genera, 456 species, 10 subspecies, 37 varieties, and 5 forms. Among the investigated 508 taxa, 2 endangered species, 8 rare plants, and 8 endemic plants were identified. The specific plants by floristic region were grouped into 71 taxa including, 3 taxa of grade V, 10 taxa of grade IV, 15 taxa of grade III, 17 taxa of grade II, and 26 taxa of grade I. Naturalized and ecosystem disturbing plants were grouped into 57 taxa and 5 taxa, respectively. The percentage of naturalized plants species and urbanization index were estimated to be 11.2% and 17.8%, respectively. This study provides important basic information for the efficient management of Hanbando wetland, which possess a high conservation value since it is forms part of the list of Ramsar wetlands.

The flora of the vascular plants in Deoksesan Mt. and its adjacent areas, located at Inje-gun, Gangwon province, were surveyed for a total ten times from April of 2018 to July of 2020. The result of this survey revealed 457 taxa, consisting of 90 families, 287 genera, 404 species, 13 subspecies, 35 varieties, and 5 forms. Among them, 12 taxa were endemic plants to Korea, and 7 taxa were rare plants. Red list plants and those designated as controlled Korean biological resources, requiring special permission for export outside of the county, numbered 3 and 103 taxa, respectively. The floristic target species amounted to 83 taxa, specifically 8 taxa of grade IV, 26 taxa of grade III, 21 taxa of grade II, and 28 taxa of grade I. In addition, 14 taxa were classified as plants adaptable to climate change, and 4 taxa at their respective northern limits, first recorded in this study, were also investigated. Twenty-nine taxa of alien plants and 4 taxa of ecosystem disturbance species were also found in this area. Our results suggest that some species should be preserved and can serve as basic information with which to establish data on the preservation of resources, such as plant diversity and distributional changes on Deoksesan Mt.

Gwangdeoksan Mountain (699.3 m) is the highest border mountain between the two cities of Chungcheongnamdo Province, Cheonan and Asan, Korea. In this study, we investigated the flora of Gwangdeoksan Mt. from April of 2015 to October of 2017. Through 20 independent field investigations, we identified and tallied a total of 428 species, 9 subspecies, 30 varieties, and a forma in 287 genera and 97 families. Of a total of 468 taxa, 128 taxa in 112 genera and 58 families were found to be Korean endemic species (7 taxa), floristic regional indicator species (45 taxa), rare or endangered species (3 taxa), species subject to the approval of outbound transfer (73 taxa), and alien or ecosystem disturbing species (32 taxa). The flora of Gwangdeoksan Mt. can be divided into four distinct floristic subregions, with higher diversity in the north-facing subregion. The complex flora of Gwangdeoksan Mt., emerging at the edge of two floristic regions of the Korean peninsula, may represent a significant conservation priority and a topic for future ecological and geographical studies.

Investigating and evaluating regionally distributed plant resources provide fundamental information (inventory) to conserve plant diversity in target areas. Nevertheless, the examination of inventory to collect information in areas with little interest has been insufficient. In this study, the vicinity of Mt. Baegamsan(1,004m) was investigated for plant resources in the central and southern part of the Korean peninsula, which has received low interest. Nine surveys identified a total of 638 taxa consisting of 108 families, 339 genera, 572 species, 12 subspecies, 49 varieties, and 5 forms. One taxon was designated to be the endangered wild plant by the Ministry of Environment, and a total of 29 taxa were designated to be endemic species in Korea. Floristic target species identified by the surveys included 1 taxon for grade V, 13 taxa for grade IV, 36 taxa for grade III, 29s taxa for grade II, and 34 taxa for grade I. A total of 38 taxa were identified to be naturalized plants, and 3 of them were designated as invasive alien plants by the Ministry of Environment. There was a difference in plant distribution between western and eastern areas of Mt. Baegamsan. The endangered and valuable plants for conservation were mainly identified from Mt. Baegamsan peak area, the ridge, and the western area. Considering the plant distribution, the Mt. Baegamsan region, located on Nakdong-jungmaek, was estimated to be dispersal routes for plant expansion and retreat.

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.
