  • Ten plots were established to study the vegetation structure of the Songinbong virgin forest in Ullungdo. It was classified into three communities Fagus crenata var. multinervis commnunity, Acer okamotoanum-Fagus crenata var. multinervis community, and Acer okamotoanum community. Shannon's diversity indicies of this area were not high(0.5150~0.8437), due to the geographical and vegetational characteristics. Considering the community structure(importance value, distribution of DBH class, and so on), the vegetation of the Songinbong virgin forest are thought to be stable continuously. With the analysis of plant growth type, it was presumed that Acer okamotoanum have increased after artificial disturbances in this area where Fagus crenata var. multinervis had been dominanat.

  • Daphne pseudomezereum var. koreana is an endangered deciduous shrub distributed in mountain areas that is vulnerable to climate change. The purpose of this study was to provide foundational data on the physical characteristics, soil environment, and vegetation structure of habitats of Daphne pseudomezereum var. koreana habitat in Korea in order to help with management decisions on ecosystem restoration. Rock exposure was 15 to 35%, with an average of 24%. The native habitat of D. pseudomezereum included 129 taxa consisting of 46 families and 95 genera. Two-way cluster analysis divided the habitat into three plant communities: Community I (dominaterd by Tilia amurensis and Quercus mongolica), Community II (dominaterd by Fraxinus rhynchophylla and Acer pseudosieboldianum), and Community III (dominaterd by Ulmus davidiana var. japonica). The diversity indices for Communities I, II, and III were 1.124, 1.047 and 0.932, respectively. The soils were loam or clay loam. Soil pH, organic matter content, and available phosphoric acid were 5.40, 14.38%, and 31.08 ppm, respectively. Ordination analysis resulted that most significant factors influencing D. pseudomezereum distribution were magnesium content of soil, shrub layer, and altitude.

  • The purpose of this study is to investigate and analyze a conservation state and a sustainable use of coastal wetland in Sindu-ri Tae-an, using the plant community structure analysis and the awareness result of local residents by published paper. To investigate a forest structure in Sindu-ri area, twenty plots were set up and surveyed. The community, is divided by three groups. The divided groups are Robinia pseudoacacia(I), Pinus thunbergii-Robinia pseudoacacia(II), Robinia pseudoacacia(III). Survey site I is simple canopy layer and deteriorative forest. Survey site II is grassland and swamp, where Pinus thunbergii-Robinia pseudoacacia is dominant trees of vegetation. Robinia pseudoacacia is competition species with Pinus thunbergii in survey site II. Survey site III is barren land(sand-hill) where main species is Robinia pseudoacacia. As a result, survey II district is considered as the most suitable for the conservation of species diversity. It is proposed in this paper that the ecological nature trail would be connected in survey site I and II for environmental education. The local residents of Tae-an, where natural environment is well-conserved, prefer conservation to development of the region. In case of Tae-an, where the condition of the natural environment is well conserved and the development potential exists, the development is in harmony with the environmental education program.
