  • This study was investigated to find out the distribution of vascular flora and remarkable plants and its factors and management plan in the forest genetic resource reserve of Mt. Munsu, located in the DMZ and DMZ border area in Gimpo, Gyeonggi-do province. The survey was carried out 17 times from April 2019 to October 2020. First of all, in the forest genetic resource reserve of the Mt. Munsu, a total of 444 taxa in 95 families, 276 genera, 395 species, 13 subspecies, 33 varieties and 3 forms. This result was found to be about 9.09% of the total 4,881 taxa of vascular plants in Korea. In addition, endemic plants were classified as 6 taxa. Floristic special and rare plants were identified as 39 taxa and 3 taxa, respectively. Lastly, the invasive alien plants that appeared in Mt. Munsu of the forest genetic resource reserve were observed in 58 taxa. Moreover, the naturalization rate was 13.1% and the urbanization index was calculated to be 18.0%. As a result of comparing the vascular flora at the forest genetic resource reserve on Mt. Munsu identified in this study with previous studies, it was found the number of taxa was decreased compared to the previous studies, despite the fact that the recent survey section was wider and more varies routes were investigated. In particular, it was confirmed that the number of rare and endemic plants decreased significantly, and the number of invasive plants greatly spread to forest roads and hiking trails. Therefore, it is considered that the forest rest year system should be introduced for the conservation and management of native plants in the forest genetic resource reserve.

The hydrophytes was listed 31 taxa of 15 families, 20 genera, 29 species, 2 varieties and Eleocharis mamillata var. cyclocarpa, Penthorum chinense, Soirodela polyrhiza were recorded in Osongjae, Sagittaria aginashi, Eleocharis kuroguwai, Scirpus juncoides, Scirpus triqueter, Monochoria korsakowi, Monochoria vaginalis var. plantaginea were recorded in Ogongjae. Besides, Scirpus fluviatilis, Trapa pseudoincisa were recorded in Shinyongjae and Scirpus triangulatus, Nymphoides peltata, Myriophyllum verticillatum were recorded in Eodujae. This site is located in the urban area and ecosystem-disturbing wild animal and plant has been imported here, therefore ecosystem has been disturbed more and more. The wetland here rapidly has changed into upland, so it needs conservation measures through long-term monitoring.

  • Gwangchiryeong, located adjacent to the Korean DMZ, is a mountain pass connecting Yang-Gu, Gangwon-do with In-je. It reaches a height of 800m (2,624ft) and stands on the flank of Mt. Daeam-san, which has an elevation of 1,304m (4,278ft). It is important to survey the flora of Gwangchiryeong in that not only the area encompassing the waterfall and the valley along with dense old-growth forest has various plant species but also it is a way to make out what kind of plant species exist in the DMZ due to the geographical characteristics of Gwangchiryeong adjacent to the Korean DMZ. Therefore, this study was conducted to elucidate the distribution of vascular plants and their value in Gwangchiryeong. The vascular plants that were collected 9 times from April 2014 to September 2015, and consisted of a total of 513 taxa: 88 families, 297 genera, 441 species, 4 subspecies, 62 varieties and 6 forms. Among those observed species, the rare plant species designated by Korea Forest Service were 22 taxa including Hanabusaya asiatica, Paeonia japonica, Saxifraga octopetala, etc. Endemic species were 22 taxa containing Cirsium setidens, Heloniopsis koreana, Salvia chanryoenica, etc. 18 taxa were recorded as naturalized plants and their naturalized rate and urban index were noted as 3.5% and 5.6%. Among the surveyed 513 taxa, edible, medicinal, pasturing, ornamental, timber, dye, fiber and industrial plants were 197 taxa, 154 taxa, 180 taxa, 49 taxa, 24 taxa, 8 taxa, 4 taxa and 3 taxa, respectively.
