What makes the structure of your CWMA successful?
Multiple agencies freely sharing information for a common good. Ability to work with one another over geographic and political boundaries as needed. Strong and positive working relationship with the Oregon Department of Agriculture Noxious Weeds Division.
 
What is the highest priority species in your area?
Garlic mustard, knotweed, false brome
 

Describe your most valuable outreach/education tool.
The newly unveiled Western Invasives Network (WIN) web site: www.westerninvasivesnetwork.org

WIN is designed to serve the needs of the six CWMAs in the Northwest Weed Management Partnership.  
What are some of your most successful on the ground accomplishments?
Adoption of formalized Early Detection Rapid Response (EDRR) training in the Columbia Gorge to foster awareness of garlic mustard among land managers, hiking groups, governmental agencies, departments of public works, state and county parks, and local state and federal agencies.
   
List your highest priority on the ground projects and why they are high priority.
Prevention of the spread of garlic mustard into the Mt. Hood National Forest and the Columbia River Gorge National Scenic Area, in order to save habitat for multiple species and to prevent the spread of an extremely invasive weed to other parts of the PNW.
 
Slowing the spread of false brome in the PNW to save critical woodland/oak savannah understory.

Slowing the spread of knotweed in riparian areas throughout the PNW to preserve habitat and large woody debris banks for salmonids.
 
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 landscape wide planning.
