CWMA MISSION: “To improve invasive weed species management county-wide through increased communication, coordination, and the sharing of technical expertise and knowledge between landowners, natural resource managers, and all interested parties. To seek funding to improve and implement on-the-ground weed management projects."

What is a Cooperative Weed Management Area (CWMA)?

The Center for Invasive Species Management defines a CWMA as "a partnership of federal, state, and local government agencies, tribes, individuals, and various interested groups that manage invasive weeds within a defined area."

All CWMA's share six basic characteristics: 

  • CWMAs operate within a defined geographic area, distinguished by a common geography, weed problem, community, climate, political boundary, or land use

  • CWMAs involve a broad cross-section of landowners and natural resource managers within its defined boundaries

  • CWMAs are governed by a Steering Committee

  • CWMAs make a long-term commitment to cooperation, usually through a formal agreement among partners

  • CWMAs have a comprehensive plan that addresses the management or prevention of invasive species within its boundaries

  • CWMAs facilitate cooperation and coordination across jurisdictional boundaries
