Describe your most valuable outreach/education tool.
A combination of brochures, workshops/tours, demonstration plots, and one on one outreach.
 
What are some of your most successful on the ground accomplishments?
Many, ranging from citizen based ivy removal projects, to multi-county knotweed and garlic mustard projects. We are embracing early detection rapid response (EDRR) in order to train individuals to spot potential invasives.
 
List your highest priority on the ground projects and why they are high priority.
Containment and control of species such as spurge laurel, garlic mustard and ED/RR species arising from within the Portland metropolitan area, decreasing the abundance of more common invasive species impacting ecological health at the urban/natural area interface, and creating an informed and supportive citizenry through publications, outreach events, and trainings.
 
What would you say is your CWMA's largest obstacle in the way of achieving your mission?
Lack of long term predictable funding prevents effective planning.
