Abstract
The characteristics of vegetation on embankment slopes with mowing management of over 10 years were studied. No significant effect of mowing frequency was noted on species diversity or degree of vegetation succession. Higher coverage of vine species and more number of bird-dispersed species were observed on slopes with high coverage of upper-story trees. Especially bird-dispersed vine species tended to survive because birds alight on these upper-story trees allowing easy seed dispersal and vines can often withstand mowing. Therefore, improvements such as reducing the coverage of upper-story trees and mowing at higher cutting height are necessary to suppress vine species.
