Abstract
This study was carried out to investigate the relationship of occurrence and distribution of Eupatorium rugosum by forest types and soil characteristics in Mt. Namsan in Seoul, Korea. E. rugosum is designated as a harmful non-indigenous plant in ecosystem by the Natural Environment Conservation Act in Korea. E. rugosum grew along roadside and in valleys with some favorable light conditions. E. rugosum occurred in aggregations under Pinus densiflora and Robinia pseudoacacia communities. And it was sparse in forests of Quercus mongolica and P. koraiensis. The representative herb layer species were Oplismenus undulatifolius, and Parthenocissus tricuspidata in the E. rugosum communities. There was a significantly negative correlation between the coverage of E. rugosum and the coverage of tree layer. However, the result of ANOVA of E. rugosum coverage by dominant species of tree layers did not show a significant difference (p>0.05). The level of soil moisture content, organic content, and pH, was slightly higher in communities with E. rugosum than without, but it was statistically non-significant difference. However, it was found that the coverage of E. rugosum was very significantly negative correlated with the depth of top soil profile (litter and fermentation layer, p<0.05).
