Thank you for your report of knapweed along Springwater Road. We have been noticing a significant amount of Meadow knapweed throughout Clackamas County. Unfortunately this species is currently not a priority species for control in Clackamas County. As such we rely upon the abutting landowner to control this species. That said, we value your report. We are annually reviewing our priority list of species to maximize the effectiveness of our control efforts. Meadow knapweed is a species under consideration your report helps us during this assessment process. Thanks again for your efforts and all the best,
Sam
