“…We used the phytosociological classification method by Braun-Blanquet which focused on the composition of plant species and two-way indicator species analysis (TWINSPAN) which was a quantitative analysis as the most typical methods for classifying the plant communities. These two vegetation classification methods were generally shown similar trends (Kim 1992, Jang et al 1997, they were very complement each other , and the TWINSPAN method for the characteristic species analysis could automatically and simultaneously classify the correlation between plant species and stands (Hill 1979, Glavac 1996. We also used canonical correspondence analysis (CCA) as one of multivariate analysis and CCA generally was used to analyze the relationship between the plant community and environmental factors.…”

We classified the streamside plant community by phyto-sociological method and analyzed the relationship between environment factors and vegetation structure by using the classification and ordination method. We found that twenty one plant communities were classified according to dominant species at the natural streamside valley forest with surveying the 65 quadrats (10 m × 10 m). From the survey results, the hardwood plant communities were classified as streamside valley forest and the softwood plant communities as riparian forest according to the degree of flooding. The valley forest had a distribution of 17 plant communities which was 65% (42 quadrats) of 65 quadrats: Maackia amurensis community, Betula davurica community, Quercus variabilis community, Pinus densiflora community, Q. serrata community, Prunus sargentii community, and Meliosma oldhamii community etc. The riparian forest had a distribution of four plant communities which was 35% (23 quadrats) of 65 quadrats: Salix koreensis community, S. rorida community, S. purpurea var. japonica community, and S. glandulosa community, etc. From the two-way indicator species analysis (TWINSPAN) analysis, we found indicator species Oplismenus undulatifolius and Lindera obtusiloba for the streamside valley forest and Humulus japonicus, Phragmites japonica, and S. koreensis for the riparian forest. From the results of the canonical correspondence analysis (CCA), coordinates, altitude, and stream structure showed low correlation to the distribution of the plant community. Therefore, it seemed that valley forest and riparian forest were distinguished by the stream gradient and waterway width which determined by the stream water level.

“…Communities Quercus mongolica and Pinus rigida in the study site, since Quercus mongolica appeared in high density in the lower layers, and the succession of evergreen conifer and planted stands tends to progress to deciduous forest, it was expected to be maintained or succeeded to communities dominated by Quercus mongolica (Kim et al, 2016). Kim and Oh (1993) suggested that changes in vegetation can be predicted through distribution analysis or less and the shrub layers. As for urban forests, tree species that are highly adaptable to urban environments, including Sorbus alnifolia and Styrax japonicus, tend to appear (Lee et al, 2006b;Kwak, 2011;Han et al, 2014), but as other tree species appeared on Mt.…”

Background and objective: Urban forests fulfill a range of functions, including promoting leisure activities and improving urban landscapes, but are different in structure from natural forests. In the case of forests near the Seoul metropolitan region, forests dominated by native tree species must be formed, but vegetation management that involves in minimal intervention is essential due to external disturbances, artificially planted species, and invasive species. This study was conducted to preferentially survey the vegetation status of Mt. Chilbosan, Gyeonggi-do with the goal of contributing to the sound use and management of the mountain.Methods: Eighty quadrats were established, and the species names and characteristics for each stratum were surveyed by dividing them into canopy, understory, and shrub layer. Based on the surveyed vegetation data, communities were classified through TWINSPAN or DCA analysis, and the characteristics of each community were examined.Results: The plant communities were classified into a total of 7 dominant groups: Quercus mongolica, Quercus mongolica-Pinus rigida, Pinus rigida-Pinus densiflora, Pinus rigida-Quercus spp., Castanea crenata-Quercus acutissima, Robinia pseudoacacia, and Pinus koraiensis. Communities dominated by Quercus mongolica and Pinus rigida had similar species and vegetation structures. Communities dominated by artificially planted tree species such as Castanea crenata, Robinia pseudoacacia, and Pinus koraiensis are distributed around the forest edges or frequently used hiking trails and are damaged by various disturbances. Overall, not only is it difficult for succession to proceed due to external influences and soil acidification, but because species with high adaptability to acidity are also expected to emerge, making long-term monitoring necessary.Conclusion: Mt. Chilbosan had a good environment, but it was disturbed by a low elevation, a drop in the groundwater level due to surrounding development, and an increase in visitors. To improve the current state, it is necessary to induce and manage the transition to native forests adapted to the urban environment by reflecting the vegetation structure's characteristics and changes.
