Eleven species of endomycorrhizal fungi were isolated from the soils in the communities of Persicaria thunbergii: A. bireticulata, A. scrobiculata, Gi. decipiens, Gi. gigantea, Gi. margarita, Gl. albidum, Gl. manihotis, Gl. pulvinatum, Sc. erythropa and Sc. gregaria.

This study presents the flow response and habitat region of the aquatic plants in the urban streams. Phragmites japonica, Phragmites communis, Miscanthus sacchariflorus, Persicaria blumei and Persicaria thunbergii were selected as for typical plants. Flow response and habitat region were determined by flow velocity/depth and vegetation growth. Stages for flow response of the aquatic plants were classified into stable, recovered, damaged and swept away. Criteria between the recovered and damaged stage was determined by the bending angle of $30{\sim}50^{\circ}$. Capability against flow was high in the order of Phragmites japonica, Phragmites communis, Miscanthus sacchariflorus, Persicaria blumei and Persicaria thunbergi. Phragmites japonica and Phragmites communis were capable of coping with flow depth 0.9 m, flow velocity 1.5 m/s and with flow depth 1.0 m, flow velocity 0.9 m/s, respectively. Miscanthus sacchariflorus was capable within the region of flow depth 1.0 m and flow velocity 0.6 m/s. Persicaria blumei and Persicaria thunbergii were less capable than the other aquatic plants and were vulnerable exceeding the water depth of 1.0 m. Habitat regions by the flow response of each plants were suggested.
