The purpose of this study was to investigate the distribution of vascular plants in Mt. Daedeukbong. The study is significant because surveying the flora of old-growth forest in Mt. Daedeukbong is a way of understanding what kind of plant species exist in DMZ as the geographical characteristics of Mt. Daedeukbong adjacent to Korean DMZ have the role of a buffer zone connecting the DMZ and its southern region. We collected the vascular plants 7 times from May 2015 to May 2017 and found a total of 393 taxa consisting of 84 families, 245 genera, 341 species, 4 subspecies, 43 varieties and 5 forms. The observed rare plant species as designated by Korea Forest Service were 8 taxa, and the endemic species were 6 taxa. 44 taxa were listed as specific plant species based on phytogeographical in the investigated area. 23 taxa were recorded as naturalized plants, and the naturalized rate and urban index were 5.3% and 8.7%, respectively.

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.

This study was conducted to investigate the vascular flora of two outstanding forest wetlands(OFW) in Goheung-gun, Jeollanam-do, and to prepare an efficient management plan for forest wetlands through comparison with previous studies. Fieldwork was conducted seasonally from May to October 2023, The flora in the two OFW located in Goheung-gun, Jeollanam-do, consisted of 117 taxa such as 55 families, 92 genera, 108 species, 7 variants, 1 variety and 1 hybrid. The endemic plants were 4 taxa and rare plants were 7 taxa. Floristic target plants were V class 2 taxa, IV class 6 taxa, III class 8 taxa, II class 4 taxa and Iclass 21 taxa. Climate change adaptation plants were 10 taxa and naturalized plants was 1 taxa. Obligate wetland plants were 16 taxa, Facultative wetland plants 10 taxa and Facultative plant 4 taxa. OFW functioning a typical wetland ecosystem in Goheung-gun had been providing habitats for a variety of rare plants, such as the Habenaria radiata and Drosera rotundifolia. But those ecosystems would be suffering a critical disturbance such as human interference, the invasion of naturalized plants, and change of wetland function through landization for a short future. Therefore we suggest those OFWs should be designated as a Forest Genetic Resource Reserve in order to keep the ecosystems permanently and to manage them more soundly and efficiently.

The Specific Plant Species such as N degree (2 species) and V degree (5 species) which is categorized by the Ministry of Environment are appeared as 7 species. II degree species among Endangered species of wild flora is Abeliophyllum distichum, and the Rare and Endangered Species which is categorized by the Korea Forest Service are enlisted as the five taxa. The Bukhansan is one of the phytogeographic ally important areas among national parks of Korea because this region is located in the northern limit of Southern Plant Types, such as Carpinus laxiflora, Cornus kousa, Styrax japonica and Zanthoxylum piperitum. The flora of the area was enlisted as 638 taxa, 103 families, 362 genera, 541 species, 87 varieties, and 10 forms. Naturalized Species was identified as 58 taxa, 16 families, 52 genera, 54 species and 4 varieties. The Ratio of Naturalized and Urbanization Index was 9.09% and 20.21%, respectively.
