Good Afternoon Ms. Cannon,
I want to thank you for submitting your report of knotweed. As you know this species is a significant problem invader within Clackamas County. The Clackamas Soil and Water Conservation District is working with regional partners to map and catalog known infestations to help prioritize future control efforts.
We have completed treatments for the 2015 field season and plants have died back for the year. We are beginning our planning efforts for the coming season. I have forwarded your report to the WeedWise Program specialist working in that area, and we will do our best to make sure that your property is in the treatment queue for next season.
Thanks again forr taking the time to report this invasive species. Please feel free to contact me if you have any additional questions.
