Well, ultimately, of course, it's up to the landowner to control Japanese knotweed on their land. I can say that we recently awarded £50,000 to five councils via the green infrastructure funding scheme to undertake a project to combat invasive non-native plant species at over 1,000 sites throughout those five counties. It will also train community volunteers to help to control those plants, and we did recently publish an updated information sheet aimed at community and voluntary groups, with advice on action on land they manage.
