As the result, transition of vegetation to adventive plant with weak root and high height has happened. It causes many problems such as reduction of erosion resistance, inhibition of monitoring of levee etc. Based on this backdrop, experiment was conducted to introduce measures to keep necessary function and reduce cost of weeding on levee vegetation.
