In recent years, wild boar rooting activity at river embankment has become a river management problem in the Watarase river and the Kiryu river and its damage number is continuously increasing. Therefore, it is necessary to conduct measures of their rooting activity.
In this study, we conducted weeding at the Kiryu river banks as measures of wild boar rooting activity at embankment slopes then verified its effect. Weeding was carried out in three different conditions, i.e. a) the whole major bed, b) major bed within 10 m from the embankment slope, and c) the embankment slope with major bed within 10 m from the embankment.
As the result, the effectiveness of the weeding was confirmed, for the weeding at the embankment slope and major bed of within 10 m from the embankment.
