The numbers of vascular plants were summarized as 273 taxa including 82 families, 182 genera, 236 species, 3 subspecies, 28 varieties and 6 forms. Woody plants were identified as 124 taxa (45.4%) and herbaceous plants as 149 taxa (54.6%). A total of 107 taxa were identified in the area of Sadam-ri, and 246 taxa were found in the Gallon valley. A total of 8 taxa of rare plants were identified, each of which was divided into 1 taxa of endangered (EN; Daphne pseudomezereum var. koreana), 3 taxa of vulnerable (VU; Paeonia japonica, Berchemia berchemiaefolia and Iris minutiaurea), 3 taxa of least concern (LC; Aristolochia contorta, Syringa patula var. kamibayshii and Goodyera schlechtendaliana) and 1 taxa of data deficient (DD; Alangium platanifolium).

Naturalization rate (NR) was 1.8% of all 273 taxa of vascular plants and the invasive alien plants were not found. The purpose of this study is to identify the flora that grows in the special protection zones of Songnisan National Park and provide the basic data for the management of the special protection zone in the future.

To investigate the distribution of vascular plants growing in Mt. Taebaeksan, a survey was conducted from April, 2014 to October, 2014. The flora of Mt. Taebaeksan was classified as a total of 406 taxa comprising of 79 families, 238 genus, 352 species, 4 subspecies, 43 varieties and 7 forma. Among them, 8 taxa were identified as endemic plants in Korea including Salix koriyanagi Kimura, Aconitum pseudolaeve Nakai, Anemone koraiensis Nakai, etc. 16 taxa of Korean rare plants species were identified including 4 taxa in the degree of VU (Asplenium spinulosum (Maxim.) Milde, etc.) and 12 taxa in the degree of LC (Clematis koreana Kom., Eranthis stellata Maxim., Aristolochia manshuriensis Kom., etc.) The floristic special plants were a total of 107 taxa which consist of 3 taxa in degree V(Polypodium virginianum L., etc.), 14 taxa in degree IV(Asplenium otophorum (Miq.) Koidz., etc.), 31 taxa in degree III (Abies nephrolepis (Trautv.) Maxim., etc.), 32 taxa in degree II(Lycopodium chinense H.Christ, etc.) and 27 taxa in degree I(Dryopteris crassirhizoma Nakai, etc.). For the naturalized plants, 16 taxa were identified (Fallopia dumetorum (L.) Holub, Rumex crispus L., Cerastium glomeratum Thuill).

This study investigated species formation and their vegetation on the roadsides of 1100 Road and 5 16 Road in Hallasan National Park from August 2004 to December 2006 to provide basic data for distributional attribute of the naturalized plants. The vascular plants investigated on the roadsides of Hallasan National Park were found to be 62 families, 145 genera, 197 taxa in total, in which naturalized plants were recorded as 11 families, 29 genera, and 37 taxa. The floristic formation at 1100 Roadside was composed of Festuca arundinacea-Dactylis glomerata association, which was again divided into Trifolium pratense-Plantago lanceolata sub-association and Sasa quelpaertensis-Gleichenia japonica sub-association. The florisitic composition of the 5 16 Roadside was sorted as Festuca arundinacea-Dactylis glomerata association, Oplismenus undulatifolius-Potentilla fragarisiiforlia, elatior association, Ambrosia artemisiifolia, and etatior-Persicaria thunbergii association. Among the naturalized plants distributed at this area, the annual plant accounts for 51.4%[19 taxa] and the plant of European origin accounts for 70.3%[26 taxa]. As for the background of the introduction of these plants, the case of introduction for forage or a mixture with grain and for pasture was 35.1% and 21.6% respectively, showing higher introduction circumstances than others. As shown in the study, most of the roadsides were occupied by the naturalized plants- Festuca arundinacea and Dactylis glomerata association and various naturalized plants; thus we can assume that it's because Festuca arundinacea and Dactylis glomerata association were mostly used for re-vegetation of the destroyed areas due to road construction or expansion or road maintenance and improvement project.

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.

In this study, we investigated the flora of Jeonggwangsan Mt. (Yongin, Korea) from May of 2015 to September of 2016. Through 14 independent field investigations, we identified a total of 367 taxa of vascular plants, including 89 families, 234 genera, 323 species, six subspecies, 34 varieties, and four formae. Eight taxa were endemic to Korea, while 27 were naturalized in Korea. Nineteen taxa were the floristic regional indicator plants in Korea: four in Rank VI, four in Rank III, two in Rank II, and nine in Rank I. A total of 59 taxa were designated as controlled Korean biological resources, requiring special permission for export to outside countries. Two taxa were listed on the Red List of Korea, including one Near Threatened (NT) taxon (Hololeion maximowiczii Kitam.) and one Least Concern (LC) taxon (Iris minutoaurea Makino).
