Securing sufficient planting strip for street shrubs has a limitation. So many different shrubs which have been planted in the streets looks consider its visual aspect rather than growth characteristics. In this study, we compared with the growth condition of planted shrubs and construction condition of its planting strip. $Photinia$ $glabra$, $Euonymus$ $japonicus$, $Camelia$ $sasanqua$, $Nandina$ $domestica$, $Abelia$ $grandiflora$ were selected in the Busan City, Korea. The planting strips width were 0.5~0.9m which is not relatively different by each species. Species which have narrow growth character of root hair in the natural bed ($Nandina$ $domestica$, $Abelia$ $grandiflora$) have a good growth condition in the street planting strip, oppositely shrubs which have wide growth character of root hair ($Photinia$ $glabra$, $Euonymus$ $japonicus$, $Camelia$ $sasanqua$) have a relatively bad growth condition. Hereupon, there have a necessity which should be select the different shrub species for the planting strip of the street.

To select new useful plants with antibacterial activity, ninety five sample of eighty different species of wild plants were collected, and extracted with methanol. Antibacterial activity of the methanol extracts was tested against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Vibrio parahaemolyticus. The methanol extracts from Artemisia capillaris, Hemistepta lyrata, Youngia japonica, Prunella vulgaris, Lamium amplexicaule and Juniperus chinensis was effective against all bacterial strains tested, and eight methanol extracts including Ixeris dentata, Gnaphalium affine, Chelidonium majus and Spiraea prunifolia exhibited the antibacterial activity against at least 3 bacterial strains. Methanol extracts from leaf of Syringa vulgaris, Drava nemorosa and clove of Erythronium japonicum showed a selective antibacterial activity against two gram negative bacteria, V. parahaemolyticus, and B. subtilis, respectively. With investigations on antibacterial activity against a certain bacterial strains tested, metahnol extracts from clove of Erythronium japonicum, Spiraea prunifolia, leaf and twig of Camelia japonica, and Drava nemorosa showed strongest activities against B. subtilis, S. aureus, E. coli, and V. parahaemolyticus, respectively. Nine methanol extracts based on the results were successively fractionated with n-hexane, chloroform, ethyl acetate and water portions, which were examined antibacterial activity against B. subtilis and V. parahaemolyticus. Among the all fractions tested, chloroform fractions of Hemistepta lyrata showed strongest antibacterial activity against both B. subtilis (17mm) and V. parahaemolyticus (29 mm). Chloroform fractions of Youngia japonica, n-hexane fractions of Artemisia capillaris, Iexeris dentata and Prunella vulgaris, and ethyl acetate fraction of leaf and twig of Camelia japonica showed relatively a strong antibacterial activity. On the other hand, Juniperus chinensis and Equisetum arvense was distributed to all fractions except for water fraction.

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.

The purpose of this study was to investigate the structure of the vegetation on the trail of Hallyeo Marine & Coastal National Park. Twenty six $10{\times}10m$ plots were established along the Jisimdo trail. The vascular plants were surveyed from March 2011 to October 2011. Camellia japonica was a major woody species in the study area, while Pinus thunbergii and Zanthoxylum ailanthoides were co-dominant tree species. There were positive correlations between Distylium racemosum and Ligustrum japonicum var. japonicum; Callicarpa japonica var. luxurians and Eurya japonical; Actinodaphne lancifolia and Cinnamomum japonicum; A. lancifolia and Machilus japonica. Positive correlations were found between A. lancifolia and P. thunbergii; Z. ailanthoides and C. japonicum. Species diversity (H') was ranged from 0.51907 to 1.0217, and was relatively low compared to those of same national parks. 10 populations of Milletia japonica which are rare and endemic species, were recorded from the list of rare and endemic species of the Ministry of Environment near by ammo dumps, this study recommend the long term habitat monitoring of the species.

A field survey was conducted from June 2005 to September 2007 to explore changes of the vegetation and life form in the man-made Wetland along the Sinpyeongcheon for 3 years after its creation. A total of 20 species including 14 families, 18 genera, 15 species and 5 varieties were planted in the Wetland which was completed in 2004. Divided by life form of the planted species, a prevalent 65% of them was composed of perennation while 4 species of woody plants i.e. Fraxinus rhynchophylla, Salix glandulosa, Camellia japonica and Nandina domestica were planted there, too. The 3-year study revealed that hydatophytes (HH) scored the biggest increase in number, followed by slight increase in the number of microphanerophytes (M), megaphanerophytes (MM), chamaephytes (Ch), nanophanerophytes (N), perennial plants (H), etc., featuring generally a similar tendency for the whole period of study. The change in vegetation area increases in the area of Typha angustata, Phragmites japonica, Phragmites communis, etc. but a sharp decrease in the area of communities for other planted species. In terms of change in the area for planted species by their life form, hydatophytes (HH), HH Th (Th(w)) reported gradual increase while microphanerophytes (M), geophyte (G), and nanophanerophytes (N) continued to record a decrease. In conclusion, selection of plants to be planted turns out to play a vital role in molding the destiny of a man-made Wetland. It seems therefore extremely important to investigate the flora, and life and growth forms of the plants planted in the man-made Wetland in an effort to choose the species that can adapt themselves to the environment from the early phase on, contributing by thus to stabilization and diversification of the damp ground in line with the progression of their succession.
