| Outline of Final Research Achievements |
We investigated the use of various plant residues to secure materials for weed control and effective revegetation management. We found that pruned branches from parks and weed residues from roadbanks were effective in both aspects. We also selected Japanese knotweed as a promising plant for vegetating roadbanks because it poses little risk of becoming a pest source. However, Japanese knotweed is also considered difficult to control. Therefore, we clarified the relationship between weed mowing and the growth of Japanese knotweed and identified effective weed mowing methods for preserving and controlling Japanese knotweed communities.

| Academic Significance and Societal Importance of the Research Achievements |
鉄道や法面、公園等の緑地管理では、雑草や剪定枝など大量の植物残渣の排出が問題となる。大量に排出されるこれらの植物残渣を雑草抑制資材とすることで、残渣を有効活用できるだけでなく、「草で草を管理する」地域循環型の雑草管理が実現する。
