We are very excited to present the updated 2020 Integrated Weed Maintenance Calendar!
This calendar was originally written by Metro for managing natural areas, but our Technical & Scientific Review Committee has updated it for a wider audience of land managers. Its intent is to provide the best treatment and timing options to control invasive plants that thrive in the Portland metropolitan area.
Our Technical & Scientific Review Committee will edit the calendar annually, as needed. If you have any suggestions for the calendar, please contact our Vice-Chair, Mitch Bixby (Mitch.Bixby@portlandoregon.gov).
