We can certainly send a communiqué to local authorities, which we do on a regular basis, advising about the proliferation of the knotweed around the country. It is more prevalent in some areas than others and, for example, it grows on river banks etc. It is presenting as a major nuisance and I have seen how it can adversely affect paths and river eco-systems. I will advise my officials to deliver the message to various local authorities through county managers, and particularly how it can come to terms with the proliferation of Japanese knotweed. I will take the Senator's advice.
