The red data of vascular plants according to IUCN valuation basis were examined five taxa; Least Concern (LC) species of both Phacelurus latifolius and Belamcanda chinensis, Not Evaluate (NE) species of Lithospermum arvense, Scorzonera austriaca ssp. glabra and Polygonatum infundiflorum. The floristic regional indicator plants found in this area were 34 taxa comprising one taxa of degree IV, six taxa of degree III, 11 taxa of degree II, and 16 taxa of degree I. In addition, the naturalized plants were identified as 46 taxa and the percent of naturalized index (NI) was 8.0%, Urbanization Index (UI) was 14.3%, respectively.

Floral study on the vegetation of 8 mountains including Taehwa-san, Mugab-san, Haehyeob-san, Guksa-bong, Gwanggyo-san, Samseong-san, Suri-san, and 200m peak neighboring to Mulwang lake was carried out from April to October, 2007. They belong to the middle part of Gyeonggi Province, and located between Lat. $37^{\circ}$13' 31.19" ${\sim}37^{\circ}$33' 3.48", Long. $26^{\circ}$43' 04.1" ${\sim}127^{\circ}$26' 28.38". Vascular plants collected in these areas were total 447 taxa composed of 386 species, 5 subspecies, 46 varieties and 10 forms of 262 genera under 92 families. The area from which the most plentiful plants were found was Mt. Gwanggyo-san. The areas with comparatively excellent vegetation are easy slopes nearby valleys in Mt. Gwanggyo-san, Mt. Suri-san and Mt. Haehyeob-san. Forests of the examined areas are generally mixed of Pinus densiflora and Quercus plants, but herbaceous plants covering soil are becoming nearly extinct by air and soil pollutions except some sites. Families with abundant species are Compositae, Rosaceae, Liliaceae and Graminae, etc. Endemic plants found in these areas are 8 taxa of Clematis brachyura, Euonymus trapococcus, Viola seoulensis, Ajuga spectabilis, Scutellaria insignis, Weigela subsessilis, Aster koraiensis, Aconitum chiisanense and rare and endangered plants are 7 taxa of Arisaema heterophyllum, Iris odaesanensis, Eranthis stellata., Aconitum chiisanense, Prunus yedoensis (cultivar), Viola albida, and Syringa wolfi. As to useful plants, 192 taxa for the edible, 132 taxa for the medicinal, 130 taxa for the ornamental and 11 taxa for the staining were classified respectively. Among 17 taxa of specially designated plants, 5th degree plants are 2 taxa of Iris odaesanensis and Prunus yedoensis (cultivar), 4th degree plants are 2 taxa of Symplocarpus renifolius and Syringa wolfi, 3rd degree plants are 13 taxa of Dryopteris gymnophylla, Juniperus chinensis, Betula chinensis, Betula davurica, Diarrhena fauriei, Aconitum longecassidatum, Eranthis stellata, Spiraea salicifolia, Acer palmatum, Vaccinium koreanum, Scutellaria insignis, Weigela florida and Adoxa moschatellina.

The purpose of this study was to investigate the flora of Mt. Bongrae in Busan from February 2004 to May 2005. The flora in the surveyed area were identified 291 taxa that belonged to 82 families, 201 genera, 251 species, 35 varieties, and 5 forms. Among them, evergreen broad trees were identified 21 taxa, naturalized plants 30 taxa, especial plants decided by Ministry of Environment 24 taxa. By the vegetation of each slope, in northeast slope, it was dominated such as Pinus thunbergii community, Chamaecyparis obtusa community, Amorhpa fruticosa community, Trachelospermum asiaticum var. intermedium-Hedera rhombea community, north-northeast slope, it was distributed both Pinus thunbergii community and board-leaved tree community. In the southwest slope of coast site, it was presented plantation plants, according to altitude distributed such as natural vegetation, evergreen broad trees, warm-temperate plants. In southeast slope, it was to represent secondary vegetation such as Alnus firma community as a forest fire. Underside was mainly to search herbs such as naturalized plants and cruciferous family as a vegetable garden. In northwest slope, it was searched trees such as Pinus thunbergii community, Lindera obtusiloba, Styrax japonca, Prunus sargentii, Aralia elata, Zanthoxylum piperitum, Akebia quinata and herb layer such as Osmunda japonica, Allium thunbergii, Liriope platyphylla, Corydalis ochotensis, Scilla scilloides, Viola orientalis. Around the top, it was distributed such as Rhododendron mucronulatum-Rhododendron schlippenbachii community, Carpinus coreana, Viburnum erosum, Sorbus alnifolia.

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.
