I want to thank you for reporting this infestation of knotweed and Garlic mustard. Both of these species are 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 are currently treating a number of patches at priority sites across Clackamas County.
Your report will help us to prioritize future knotweed and garlic mustard treatments. So thank you for taking the time to report this invasive species. Please feel free to contact me if you have any additional questions.
