The Columbia Gorge Cooperative Weed Management Area (CWMA) exists to foster and support collaborative weed management among public land managers and private landowners. Because weeds travel over the landscape and extend across multiple ownerships, collaboration and partnerships are essential for effective weed management. In addition, partnerships increase capacity, professional expertise, efficiency, and access to new and diverse funding sources. The intention of the CWMA is to provide guidance to local government and land managers on methods for utilizing available resources to control invasive weed problems regardless of political boundaries. The Columbia Gorge CWMA promotes weed education and outreach, weed inventory and prevention, and weed control activities.
Prevent the introduction and control the spread of harmful invasive plant species in the Columbia Gorge CWMA region by facilitating cooperative management among all willing land managers.
- Manage the Columbia Gorge CWMA through information sharing and relationship building.
- Inventory and assess weeds.
- Conduct outreach to raise awareness about weeds among the wider public.
- Sponsor effective and innovative weed control and native plant restoration projects.
