  • To investigate the forest structure in valley of Kumpotan-Paekryunsa of Tokyusan National Park, fourty plots were set up and surveyed. According to the analysis of classification by TWINSPAN, community divided by 8 groups. The divided groups are Carpinus laxiflora-C. cordata community(I), Pinus densiflora-C. laxiflora-Quercus serrata community(II), C. laxiflora community(III), Q. mongolica-C. laxiflora community(IV), Q. spp. community(V, Ⅵ), and Fraxinus mandshurica community(Ⅶ, Ⅷ). In the analysis of ordination techniques, DBH distribution, environmental variables etc., community Ⅶ and Ⅷ were pointed out edaphic climax. So the successional trends seems to be from P. densiflora through Q. mongolica, Q. serrata to C. laxiflora, C. cordata, F. mandshurica in canopy layer. And in the subtree and shrub layer, it was expected that Rhododendron mucronulatum, Rh. schlippenbachii, Rhus trichocarpalongrightarrowAcer pseudo-sieboldianum, Lespedeza maximowiczii, Euonymus oxyphyllus, Symplocos chinensis for. pilosalongrightarrowStaphylea bumalda, Weigela subsessilis. According to the results of the analysis for the relationship between environmental variables and species, F. mandshurica correlated with exchangeable cations significantly.

  • This study investigated species formation and their vegetation on the roadsides of 1100 Road and 5 16 Road in Hallasan National Park from August 2004 to December 2006 to provide basic data for distributional attribute of the naturalized plants. The vascular plants investigated on the roadsides of Hallasan National Park were found to be 62 families, 145 genera, 197 taxa in total, in which naturalized plants were recorded as 11 families, 29 genera, and 37 taxa. The floristic formation at 1100 Roadside was composed of Festuca arundinacea-Dactylis glomerata association, which was again divided into Trifolium pratense-Plantago lanceolata sub-association and Sasa quelpaertensis-Gleichenia japonica sub-association. The florisitic composition of the 5 16 Roadside was sorted as Festuca arundinacea-Dactylis glomerata association, Oplismenus undulatifolius-Potentilla fragarisiiforlia, elatior association, Ambrosia artemisiifolia, and etatior-Persicaria thunbergii association. Among the naturalized plants distributed at this area, the annual plant accounts for 51.4%[19 taxa] and the plant of European origin accounts for 70.3%[26 taxa]. As for the background of the introduction of these plants, the case of introduction for forage or a mixture with grain and for pasture was 35.1% and 21.6% respectively, showing higher introduction circumstances than others. As shown in the study, most of the roadsides were occupied by the naturalized plants- Festuca arundinacea and Dactylis glomerata association and various naturalized plants; thus we can assume that it's because Festuca arundinacea and Dactylis glomerata association were mostly used for re-vegetation of the destroyed areas due to road construction or expansion or road maintenance and improvement project.

  • Lonicera harae is a species of shrub in the Caprifoliaceae family, mostly distributed in East asia. So far, the related research on the genus of Lonicera is insufficient compared to the Lonicera japonica belonging to the same genus, which requires attention to domestic native plants. Therefore, this study aims to provide baseline data for cultivation and utilization through the growth environment and vegetation structure of the natural habitat. Lonicera harae, which plant found throughout the Korean Peninsula. The natural habitats of Lonicera harae is the forest, valley and lowland areas of the southern region. study examined 24 quadrats in 11 regions, including Gwangju, Wanju and Namhae. As a result, environmental condition of Lonicera harae was 8 to 483 m above sea level, normally distributed over 173 m, Slope was 5 to 25 degree with 8.5 degree on average. The list of plants were classified as a total of 229 taxa comprising 80 families, 166 genus, 198 species, 3 subspecies, 24 varieties, 4 forma. As a result of the clustering analysis, the three clusters were divided into three groups; Robinia pseudoacacia, Zelkova serrata, Larix kaempferi. Species diversity was 1.399 and Dominance and Evenness were found to be 0.978 and 0.022 respectively.
