This study was carried out to investigate the flora of Mt Hanseok (Inje-gun, Gangwon-do) from March, 2013 to August, 2014. Vascular plants were summarized, numbering 603 taxa including 101 families, 337 genera, 520 species, 5 subspecies, 69 varieties and 9 forms. Among the 603 investigated taxa, 14 Korean endemic, 17 rare plants and 99 plants specially designated by the Ministry of Environment were also included. Naturalized plants amounted to 37 taxa. The percentage of naturalized plants species and the urbanization index were estimated to be 6.1% and 11.5%, respectively. Useful plants of the 603 taxa listed consist of 223 taxa (36.9%) which are edible plants, 217 taxa (35.9%) which are pasture plants, 165 taxa (27.3%) as medicinal plants, 67 taxa (11.1%) as ornamental plants, 22 taxa (3.6%) which are timber plants and 9 taxa (1.4%) of miscellaneous plants.

A floristic, field research was conducted from March 2005 to October 2012 the Woraksan National Park (N $36^{\circ}46^{\prime}{\sim}36^{\circ}59^{\prime}$, E $128^{\circ}02^{\prime}{\sim}128^{\circ}19^{\prime}$) to characterize the flora of the region. Especially, we divided the surveyed region into nine representative collection areas based on floristic components were compared and analyzed. This field study discovered significant plants in various categories. The 41 surveys revealed that the vascular plants in this region comprised 815 taxa: 116 families, 429 genera, 717 species, 4 subspecies, 78 varieties and 16 forms. In this study, 80 taxa were firstly recorded from this region. Korean endemic plants numbered 22 taxa, and the fifteen taxa rare plants designated by Korean Forest Service as were found in this region. The taxa in the category II of rare and endangered plants and the taxa with the higher rank than the third degree among the floristic regional indicator plants designated by Korean Ministry of Environment were one and 56, respectively. From a geographical perspective, limited distributions of Matteuccia struthiopteris, Spiraea trichocarpa, and Aster tataricus at a latitudes higher than that of Woraksan National Park. Moreover, this study has confirmed that the Woraksan National Park is the species diversity center for Asarum koreanum, Elsholtzia angustifolia, and Allium linearifolium in the central province of the Korean peninsula. Inaddition, the naturalized plants of 54 taxa were recorded.

This study was investigated to find out the distribution of flora and remarkable plants and factors and management measures for influx of wild disturbed plants in the Damyang area of Mudeungsan National Park. The field survey was carried out 8 times from May 2019 to October 2020. First of all, in the Damyang area of Mudeungsan National Park, a total of 603 taxa in 107 families, 349 genera, 531 species, 57 varieties, 5 subspecies and 10 forms. This result was found to be about 12.33% of the total 4,881 taxa of vascular plants in Korea. In addition, Rare plants were classified as 15 taxa. Floristic special and Korean endemic plants were identified as 85 taxa and 13 taxa, respectively. Lastly, the naturalized plants that appeared in the Damyang area of Mudeungsan National Park were observed in 45 taxa with 45 species of 16 families and 36 genera. Moreover the naturalization rate was 7.46% and the urbanization index was calculated to be 14.01%. The wild disturbed plants were found in a total of 4 taxa. Especially, a sheep sorrel(Rumex acetosella) was focused on managing for physica and biological control at Sinseondae Eoksaepyungjeon.

The aim of this study was to examine whether the guideline by the Ministry of Environment (ME) successfully and appropriately applied the IUCN Red List criteria at regional level and the rare and endangered national list considered eligible. A certain number of vascular plants, which are widely distributed in the world or in east Asia, deemed to be ineligible for assessment at a regional level as Not Applicable category (NA), because it occurs at very low numbers in South Korea. Among 377 vascular plant taxa evaluated by the ME, NA included 238 species, which represented 63.1%. The number of synonymized species or illegitimate name species were 13 species, which accounted for 3.4%. 21 species (9.3%) were threatened at global level and 103 species were possibly candidates species list for Red List assessments at regional level in the near future. The proportion of NA or waiting list was 66.6% among the list assessed by the ME. The most common errors involved incorrectly application of species extinction in case of population extinction in South Korea to the assessment and provided incorrect interpretation of the Red List criteria at regional level. The most assessments proposed by ME were not backed up without quantitative data quality, justifications, and sources. It is suggested that the risk of extinction should be reassessed at least in the Korean peninsula within the light of their overall distribution including far eastern Russia and North eastern China in north and for Japan and Taiwan in south for regional assessment. The results obtained here using the IUCN criteria at regional level showed that the list proposed by the ME produced an overestimation of the number of threatened vascular plants. Also, the misapplication of the term 'species extinction' for regional assessment was open to some degree of subjectivity and misinterpretation.
