Good afternoon Mr. Jones,
Thank you again for this report of knotweed. As mentioned in my previous response Japanese knotweed is a significant problem invader in riparian communities within Clackamas County.
Please feel free to contact me if you have any additional questions. You may also check these online resources for more information on knotweed.
Again thank you for reporting this invader. All the best,
