Invasive Species Removal

Species that aren't native to Oregon cost us millions of dollars per year. If you recognize any of those listed below, please do your best to get rid of them! If you see a suspect species, call us at 503-303-4372, and we'll come check it out.  You can also try to identify the suspect using our fact sheets, which were developed by students at the Art Institute of Portland.

You can also report invasive species by calling or visiting the Invasive Species Hotline website. The Clackamas County Soil & Water Conservation District is engaged in weed mapping and invasive removal activities, and would love to know where you've spotted offending trees and shrubs.
We recommend doing research before removing invasive species. Some species, such as Japanese Knotweed, are best destroyed using pesticides. Manual removal may cause the invasive weeds to spread. If you’re not sure how to get rid of an invasive species, call CRBC or visit these links for more information:
