The order of Rhododendro-Quercetalia mongolicae representing temperate oak forests in Korea was characterized in terms of presence of taxa of different rank. 140 releves were analysed for percentage contribution of each species, genera and families in syntaxa under consideration as well as extracton of diagnostic genera and families for syntaxa by an ordination technique. The Rhododendro-Quercetalia is characterized by high diversity of tree and shrub species contributing 40% of the total floristic composition as well as by a high contribution of the genus Rhododendron and the absence of the genus Fagus, characteristic of the QuercoFagetea sensu lato. The character families for the Rhododendron and Quercus include Liliaceae and Compositae, whereas Acer, Carex, Viola, Rhododendron and Quercus are the most common among genera. Rhododendron and Quercus are regarded as the transgressive cheractergenera, whereas the families of Pinaceae and Ericaceae are considered companions (in sense of the terminology of the Braun-Blanquet syntaxonomy) for the order. Family appeared to be an inadequate rank for diagnoses of alliances and suballiances. On the other hand, genus was found to be the most effective rank in differentiating the alliances and suballiances. The Lindero-Quercenion shares the same character-genera with the order Rhododendro-Quercetalia. Character genera of the suballiances Callicarpo-quercenion are Carpinus, Styrax, Smilax and Callicarpa, and those of the Pino-Quercion list Euonymus, Saussurea and Tilia.

The vascular plant species in the areas of Gonamsan and Shiribong in the Baekdudaegan were summarized as 295 texa: 89 families, 193 genus, 245 species, 44 varieties and 6 forms.10 taxa were recorded in the surveyed areas as the Korean endemic plants: Hosta capitat (Liliacease), Polygonatum lasianthum var. corenum (Liliaceae), Chloranthus japonicus (Cloranthaceae), Salix hulteni (Salicaoeae), Clematis richotoma (Ranunculaceae), Spiraea prunifolia for. simpliciflora (Rosaceae), Vicia unijuga (Fabaceae), Viola albida (Violaceae), cornus walter(Cornaceae), Weigela subsessilis (Caprifoliaceae).According to the list of Korean rare and endangered plants complied in the studied areas:Iris ensata var. spoyanea(Iridaceae), Viola albida (Vioaceae) and Aristolochia contorta (aristolochiaceae) Due to the rapid destruction and increase of visitors and the studied areas are located close to the villages, the naturalized plant species in the areas were more frequently appeared than the rare and endangered plant species.

The vascular plants in Mt. Cheongwan, Jangheung-gun, Jeollanam-do, were consisted of 599 taxa; 117 families, 366 genus, 519 species, 76 varieties and 4 forma. From the floristic point of view, Mt. Cheongwan is distributed to both the evergreen trees as Pteris mulfida, Dryopteris bissetiana, Torreya nucifera, Cephlotaxus koreana, Neolitsea sericea, Quercus acuta, Hedera rhombea, Fatsia japonica, Camellia japonica, Eurya japonica, Thea sinensis, Acorus gramineus, Pseudosasa japonica and Sasa borealis, and the deciduous subtropical trees such as Carpinus coreana, Aphanth aspera, Orixa japonica, and Lygodium japonicum And it is worth special mention to be discovered Selaginella rossii, Corylopsis coreana, Stewartia koreana, Asarum sieboldii, Viola orientals, and Drosera royundifolia. The Specific plants which is categorized to the Degree by the Ministry of Environment recorded as 45 taxa; 1 species each for the Degree II, IV and V, 5 species for the Degree III, and 37 species for the Degree I.

The vascular plants in Baekdudaegan of the South Korea were recorded of 1,477 taxa; 126 families, 641 genus, 1,248 species, 3 subspecies, 204 varieties, 22 forma. From the floristic point of view, Jirisan, Backunsan and Duckyusan District in the Baekdudaegan belongs to the southern province in Korea, appeared to Cephalotaxus koreana, Lindera obtusiloba, Lindera erythrocarpa, Lindera glauca, Izex macropoda, Meliosma myriantha, Melisoma oldhami and Stewartia koreana. But on the top regions of these mountains more than 1,000m above the sea level were contained many alpine plants. And on the top regions and ridgeline parts of Duckyusan and Jirisan were the middle province, owing to Betula costata, Betula ermani, Ulmus laciniata, Isopyrum raddeanum, Hylomecon vemale, Viola diamantica, Vaccinium koreanum, Heloniopsis orientalis, Disporum ovale, Symplocarpus renifolius and Veronica arvensis. These results were epresented that plant species of the middle province moved to the South along the ridgeline of Baekdudaegan, on the other hand plants of southern province had biological niche of low ground according to go toward the North.

This study was conducted to investigate the vascular plants which can be an indicator of environmental change in Seseok of Jirisan National Park. The purpose of this study was to find out the basic information for the subalpine species. This study showed that the area had a total 295 taxa including 63 families, 177 genus, 252 species, 2 subspecies, 36 variants 5 forms and Pte-Q was 1.7. Among them, Korea endemic plants were 15 taxa such as Abies koreana. Rare plants were 14 taxa such as Viola diamantiaca. Naturalized plants consisted of 5 taxa such as Rumex crispus. The floristic regional indicator plants found in surveyed area were 72 taxa comprising 3 taxa of grade V, 7 taxa of grade IV and 24 taxa of grade III. In summary, The subalpine plants of the survey region consisted of 37 taxa including Abies koreana and Gymnadenia cucullata. As rare plants distributed in subalpine zone respond sensitively to climate change, accuracy distribution range, environmental characteristics of habitat and population dynamics of rare plants should be evaluated quantitatively.

To investigate the distribution of vascular plants growing at Halmibong(1,026m) and Gusibong(1,014m) in Baekdutrail, we surveyed from March in 2013 to March in 2014. The flora of Haimibong and Gusibong in Baekdu trail were found to be; 528 taxa; 95 families, 287 genus, 454 species, 4 subspecies, 59 varieties, 11 forma. Rare plants were found to be; 15 taxa, 10 families, 14 genus, 13 species, 2 varieties. Among them EN degree was found to be 1 species(Rhododendron tschonoskii Maxim.), VU degree; 2 species(Scorzonera albicaulis Bunge, Lilium cernuum Kom.), LC degree; 12 species(Abies koreana Wilson, Coreanomecon hylomeconoides Nakai, Viola albida Palib. etc.) respectively. In all surveyed areas, a total of 15 taxa(Heloniopsis koreana Fuse, N.S.Lee & M.N. Tamura etc.) were found to be endemic to Korea. Distribution of floristic special plants in the surveyed areas were found to be divided into five classes (class I~V). The floristic special plants found in surveyed areas were 2 taxa of grade V, 6 taxa of grade IV, 12 taxa of grade III, respectively. The naturalized plants were investigated as 23 taxa; Rumex crispus L., Amorpha fruticosa L., Veronica arvensis L. etc..
