Thanks so much for reporting knotweed.
I will look into who may be able to respond to this and your other reports and get back to you.
Unless the knotweed is located in a waterway or impeding other important land uses, it is unlikely to get prioritized for response; however, it is extremely valuable to know its current distribution for planning purposes. So, keep on reporting!
Thanks, Tania
