This study was carried out to investigate the efficacy of antifungal and antibacterial activity of Veratri Herba, which was used as insecticide in the clinical part of oriental dermatology for a long time. Sample herb was selected with Veratrum maackii in the middle of 5 veratrum species. The experimental results of this herb were as follows. Crude extract showed various relative inhibitory rates from 68.9% to 95.6% in 2mg/disc against Fusarium oxysporum, Botrytis cineria, Saccharomyces cerevisiae, Escherichiae coli, and Bacillus subtilis on the basis of inhibitory range against B. cineria, and the inhibitory effect was decreased depending on density. In the extract of various organic solvent, chloroform and ethyl acetate fraction show the various size of dear zone against all microbes. And in the subfraction assay from ethyl acetate fraction, crude alkaloids show the antibacterial and antifungal effect significantly.

To obtain the basic data for monitoring and the conservation of native plant species at the sub-alpine zone Jongseogdae in Jirisan (Mt.).40 plots(5m${\times}$5m) set up by random sampling method and the distribution of native shrub and herb species at the subalpine zone was surveyed. Leading shrub species at the subalpine zone of Jongseogdae were Tripterygium regelii with IP value of 23.45% : followed by Lespedeza maximowiczii, Symplocos chinensis for. pilosa and Lespedeza tomentella. Dominant species at the subalpine zone were Lysimachia clethroides, Pteridium aquilinum var. latiusculum, Synurus deltoides, Veratrum maackii var. japonicum, Hemerocallis fulva and Astilbe chinensis var. davidii. Rhododendron tschonoskii recorded from the rare and endangered species list of the Korea Forest Service distributed among the rocks on the top of Jongseogdae. The long-term sustainable habitat monitoring might be required to conserve this subalpine zone.

The vascular plants in the Eco-Arboretum site, Mt. Gumwon appeared to be 369 taxa; 84 families, 217 genera, 319 species, 43 varieties and 7 forms. Based on the list of the rare plants, 2 taxa existed in the studied areas; Abies koreana (Preservation priority order; No. 73), Paeonia obovata (No. 97) and based on the list of Korean endemic plants, 12 families, 14 genera, 11 species, 3 varieties, 1 hybrid, 15 taxa existed; Cephalotaxus koreana, Abies koreana (Planted species), Carex okamotoi, Salix hallaisanensis, Salix purpurea var. japonica, Clematis trichotoma, Thalictrum actaefolium, Lespedeza ${\times}$ tomentella, Vicia nipponica, Stewartia koreana, Hypericum attenuatum var. confertissimum, Paulownia coreana (Planted species), Weigela subsessilis, Aster koraiensis (Planted species). Specific plant species by floral region were total 38 taxa; Paeonia obovata in class V , 13 taxa (Lilium leichtlinii var. tigrinum, Betula costata, Betula davurica, Ulmus davidiana, Spiraea frutschiana, Prunus maackii, Syringa reticulata var. mandshurica, Cynanchum inamoenum, Lonicera subhispida, Cacalia firma, etc.) in class III , 5 taxa (Heloniopsis orientalis, Chrysosplenium pilosum, Acer triflorm, Viola tokubuchiana var. takedana, Teucrium veronicoides, etc.) in Class II . 19 taxa (Dryopteris erythrosora, Arisaema ringens, Veratrum versicolor, Polygonatum inflatum, Salix glandulosa, Betula schmidtii, Alnus hirsuta, Quercus variabilis, Aconitum japuense, Dicentra spectabilis, Chrysosplenium flagelliferum, Impatiens noli-tangere, Ilex macropoda, Tilia amurensis, Fraxinus mandshurica, Trigonotis icumae, etc.)in class I . The naturalized plants in this site were 5 families, 13 genera, 15 taxa (Rumex acetocella, Rumex obtusifolius, Trifolium repens, Oenothera odorata, Erigeron annuus, Erigeron philadelphicus, Bidens frondosa, Taraxacum officinale, etc.) and naturalization rate was 4.1% of all 369 taxa vascular plants.

This study was conducted to analyze forest vegetation structure in the Marugeum (Ridge) area of Gitdaebaegibong to Jukryeong, Baekdudaegan. Data were collected in 298 quadrates through a Braun-Blanquet vegetation survey from April, 2018 to October, 2018. Forest vegetation was classified into 13 vegetation units. A Quercus mongolica community was divided into Morus bombycis, Filipendula glaberrima, Fraxinus sieboldiana, Prunus maackii unit and Q. mongolica typical unit. The M. bombycis unit was further classified into a Deutzia glabrata group and M. bombycis typical group. The F. glaberrima unit was subdivided into a Veratrum oxysepalum group, Arundinella hirta group, and F. glaberrima typical group. The F. sieboldiana unit was divided into a Pinus densiflora group, Larix kaempferi group, and F. sieboliana typical group. The relationship between vegetation units and environmental factors was studied through coincidence analysis and CCA. The F. glaberrima unit (VU 6~8) was distributed by elevation above 1,200 m and other vegetation units were distributed below 1,200 m. Results of the CCA analysis showed that the F. glaberrima unit distribution is positively correlated with elevation. As a result of species diversity, the F. glaberrima unit was higher than other vegetation units. A similarity index analysis revealed that the F. sieboldiana unit (VU 9~11) was relatively homogeneous, and the M. bombycis unit (VU 1~5) and A. girta group (VU 7) were relatively heterogeneous. A detrended correspondence analysis determined that the distance between the statistical axes of the M. bombycis and F. glaberrima units was the greatest, which is consistent with the analysis of the similarity index. As a result of interspecific correlation of major woody plants, hydrophilic species were positively correlated, and a negative correlation was found between Q. mongolica and intolerant species such as P. densiflora and L. kaempferi.
