Thanks so much for reporting knotweed on the hotline. I will use this report to notify someone about the infestation. It may just be mapped as part of a larger database if the infestation is not in a priority area for control. However, a good knowledge of knotweed distribution is critical to strategic management, so these reports are highly valued even if we cannot control right away.
Thanks!
