This study was carried out to analyze Pinus densiflora forest in islets of southwestern coast of the Korean peninsula by the phytosociological methods. As a result of the investigation of 26 quadrats, the pine forest was classified two communities and six subcommunities : Ardisia japonica-Pinus densiflora community and Isodon japonicus-Pinus densiflora community, and Farfugium japonicum subcommunity, Quercus serrata subcommunity, Typical subcommunity of Ardisia japonica-P. densiflora community, Juniperus rigida subcommunity, Pourthiaea villosa subcommunity and Typical subcommunity of Isodon japonicus-P. densiflora community. The subsidiary knowledges from this study provide practical information to clarify the syntaxonomy of natural pine forest of the Korean peninsula by the phytosociological methods.

Though there is an on-going need for the diversity of ornamental plants for in-door environment, their growth and stress adaptability in comparatively low light intensity condition require further studies for implementation. Here investigates the growth and chlorophyll fluorescence parameters of Farfugium japonicum (L.) Kitam, Liriope muscari (Decne.) L.H.Bailey and Acorus gramineus Aiton under several light intensities which were based on common in-door environment. The growth measurement of the plants included the quantity, length, width and SPAD value of the leaves. Calculated values of Fm/Fo, Fv/Fm, Pi_Abs, ETo/RC and DIo/RC were used as the parameters of the chlorophyll fluorescence under 10, 50, 100 and 200 PPFD (μmol·m^-2·s^-1) light intensities. In-door plants group was put in a closed room allowing no other light sources for 10 weeks and the control group was put in glass-greenhouse for the same period. The overall in-door growth of L. muscari was not significantly different in all light intensities compared to the control group and even showed the higher SPAD values. Also, an increasing tendency of Pi_Abs value under 10 to 100 PPFD was observed implying that L.muscari could adapt well to in-door environment. Measurement of A. gramineus growth mostly showed the highest values in the control group especially in the number of the leaves. Nevertheless, chlorophyll fluorescence parameters showed no significant value difference between in-door and the control groups and thus, A. gramineus might have possibility of successful adaptation to in-door environment. F. japonicum showed deficient growth in plant height and leaf length compared to the control but, it seemed to be able to sustain ornamental value under in-door light intensities. Furthermore, Pi_Abs and DIo/RC values were increased under in-door light conditions suggesting potential adaptability of F. japonicum.

We investigated the flora of Ui Island sand dunes, consisting of 142 taxa; 52 families, 108 genera, 124 species, 15 varieties, and 3 forms. The total plants of floral region that were identified were 16 taxa; Elymus mollis, Salsola collina, and Farfugium japonicum in Class III; Ischaemum anthephephoroides, Carex kobomugi, Glehnia littoralis, Messerschmidia sibirica, Machilus thunbergii, Elaeagnus macrophylla, and Aster spathulifolius in Class I . Naturalized plants were 11 taxa; 7 families, 10 genera and the naturalization degree was 7.8%. On the Donmok seaside area, the coverage rate was about $20%{\sim}25%$ in 2002, but this time it had increased to more than three times or $65%{\sim}75%$. Also, on the Sungchon seaside area, the coverage rate was about $15%{\sim}20%$ in 2002, but this time it was $70%{\sim}75%$ as a result of the rapid increase of Zoysia macrostachya and Carex kobomugi. Pungseong sand dune area showed a monotonous state in variety and number, because of the strong wind and repetition of sand income and outcome.

This study was carried out to select suitable plants for beach revegetation as a preliminary study for quantifying the effect of decreasing sand movement. After planting some herbal plants in field, monitoring of temporal change of vegetation coverage which was index of the growth rate was conducted. Through literature reviews, 24 candidate plants for beach revegetation were selected, then seven species of them, Peucedanum japonicum Thunb., Dianthus japonicus Thunb. ex Murray, Sedum oryzifolium Makino, Sedum takesimense Nakai, Sedum spectabile Boreau, Farfugium japonicum (L.) Kitam., Aster sphathulifolius Maxim. were picked through salinity tolerance experiments in laboratory. Seven species selected by salinity tolerance experiments and two additional herbal plants, Prunella vulgaris var. lilacina Nakai and Linaria vulgaris Mill., not the candidates, were nine final species which were planted in the beach around Osan port, Uljin, Korea. The changes of vegetation coverage of each species were investigated from photos periodically taken for about a year using image processing methods. As a result of the monitoring, Sedum takesimensei, Dianthus japonicus and Aster sphathulifolius were observed with high coverages during the whole monitoring while Prunella vulgaris var. lilacina and Linaria vulgaris were observed with low coverage during the same period. Consequently, Sedum takesimensei, Dianthus japonicus and Aster sphathulifolius were concluded as the most suitable plants for beach revegetation. Furthur study to quantify the effects of decreasing sand movement by the selected species is needed.

The ethnobotanical study was conducted to record and conserve the traditional knowledge of botanical taxa in Hallyeo-Haesang National Park area, S. Korea from 2012 to 2013. According to the survey results, derived from 1,430 sheets of 183 residents at 70 places, the ethnobotanical plants in Hallyeo-Haesang National Park area consisted of a total 247 taxa; 82 families, 197 genera, 224 species, 3 subspecies, 19 varieties and 1 form. The analysis of usage for 247 taxa showed that the edible use was the highest with 166 taxa, followed by medicinal with 138 taxa, craft with 27 taxa, material with 16 taxa and ritual with 9 taxa respectively. The leaf of plant was the most useful part, followed by stem and fruit plant. Quantitative analysis of the ethnobotanical plants in Hallyeo-Haesang National Park area was performed by the basic values of FC, NU and UR, and indices of CI, RFC, RI and CV. As a result, The CI places Artemisia princeps in the first position, followed by Pueraria lobata, Taraxacum platycarpum. The RFC place A. princeps in first position, followed by Achyranthes japonica, Aster scaber. The RI places A. princeps in the first position, followed by P. lobata, Pinus densiflora. The CV places A. princeps in the first position, followed by P. lobata, A. japonica. Farfugium japonicum had been used as specific ethnobotanical plant in this area, for arthralgia, postpartum arthrodynia, circulatory disturbance.
