This study was analyzed and investigated to evaluate ecological distribution of medicinal plants in Miho Stream of Korea. Totality 463 taxa of vascular plants were appeared in lower part of Miho Stream. Medicinal plants were distributed 253 taxa, which were 54.6% of the total vascular plants appeared. Medicinal plants of official drug compendium(Korean pharmacopoeia) were 85 taxa. Medicinal plants were distributed most of the forest area, and followed field surrounding, stream surrounding and paddy surrounding respectively. The distribution of life form hemicryptophyte was the most frequent. Plant community of appearing area of medicinal plants was classified into Salix koreensis, Phragmites japonica, Echinochloa crusgalli, Artemisia selengensis, Miscanthus sacchariflorus, Setaria faberii, Panicum dichotomiflorum, Bidens frondosa, Humulus japonicus, Monochoria vaginalis var. plantaginea, Eleocharis kuroguwai, Erigeron acris, Pinus densiflora, Pinus rigida, Quercus acutissima, Quercus serrata, Robinia pseudoacacia and Castanea crenata community.

This study aimed to elucidate the distribution of vascular plants on the Deok mountain in Ganghwa-gun, Korea. The results of 10 field surveys from March to October of 2019 identified 532 taxa in total, representing 482 species, 9 subspecies, 39 varieties, 1 form, and 1 hybrid in 318 genera and 105 families. The plant formation of Deok mountain is the deciduous broad-leaved and conifer mixed forest, which is the common one in the middle region of the Korean Peninsula. Among them, 301 taxa were newly recorded in this study, 7 taxa were endemic plants to Korea, 3 taxa were red list plants. The floristic target plants amounted to 41 taxa, specifically 1 taxon of grade V, 2 taxa of grade IV, 7 taxa of grade III, 9 taxa of grade II, and 22 taxa of grade I. Alien plants were recorded a total of 73 taxa with a naturalized index of 13.7%, the urbanization index was calculated to be 11.8% and 4 taxa were ecosystem disturbance plants.

Furthermore, Ⅳ, Ⅲ degrees of floristic regional indicator plants, designated by the Korean Ministry of Environment, were included 8 taxa and 14 taxa, respectively. Based on the usefulness, edible, pasturing, medicinal, ornamental, timber, stain, industrial, fiber and unknown usefulness plants included 352 taxa, 107 taxa, 71 taxa, 18 taxa, 8 taxa, 5 taxa, 3 taxa, 2 taxa and 111 taxa, respectively.

This study was carried out to illuminate the flora of vascular plants of islands at Chungnam. This study was conducted from March to November, 2010. Based on the voucher, vascular plants of in investigated islands were 105 families 326 genera 454 species 4 subspecies 45 varieties 9 forms, totally 512 taxa. Korean endemic plants were 6 species such as Aster koraiensis, Salix koriyanagi, Indigofera koreana, Hemerocallis taeanensis, Hepatica insularis, Philadelphus schrenckii, rare and endangered plants of designated by Korea Forest Service were 4 taxa, such as Magnolia kobus (planted), Koelreuteria paniculata, Berchemia racemosa var. magna, Glehnia littoralis respectively. Phytogeographical special plants were totally 69 taxa, which were grade I of 50 taxa, grade II of 1 axon, grade III of 11 taxa, grade IV of 4 taxa, and grade V of 3 taxa. 14 southern plants and 4 northern plant by criterion from climate change study were found in this area. Naturalized plants were 17 families 46 taxa, that was 9.1% of total vascular plants in this area. Even naturalized plants has not influence on the islands vegetation. However, regular passenger ferry between islands and increasing of visiter will be affecting vegetation.

In order to investigate vertical plant distribution on Namdeogyu of Mt. Deogyu National Park by temperature change, vascular plants of nine areas with 100-meter-high difference were surveyed from the Deogsangyo (650m alt.) to the Namdeogyusan (1,507m alt.). A total of 455 taxa belonging to 99 families, 280 genera, 402 species, 5 subspecies, 43 varieties, 4 forms and 1hybrid were vegetated on survey areas. Around 700 m high did species diversity of vascular plants decrease rapidly. The Detrended correspondence analysis (DCA) divided distribution of vascular plants into five groups; areas below 700m alt., 700~1,100m alt., 1,100~1,300m alt., and areas above 1,300m alt.. These results showed that vegetation of vascular plants on investigated areas has high correlation with climate elements of temperature. Vascular plants should be crowded within their own optimal ranges of vegetation. Climate change would result in shift of these distribution ranges, and thus vegetation shift will be happened accordingly.
