To ask the Scottish Government whether Transport Scotland is required to treat Japanese knotweed growing on the verges of trunk roads.
Transport Scotland is not required to treat Japanese knotweed growing on the verges of trunk roads but does include relevant terms in its contract arrangements with trunk road operating companies.
As part of their contractual duties, the operating companies are required to record all evidence of Japanese knotweed occurring within their areas of operation and to develop programmes for the control of the species.
