Introduction and Background

Cooperative Weed Management Areas (CWMAs) are partnership organizations formed with the goal of managing invasive plants across jurisdictional and landownership boundaries. Cooperative Invasive Species Management Areas (CISMAs) and Partnerships for Regional Invasive Species Management (PRISMs) are similar to CWMAs, but their goals may include the management of invasive animal species in addition to plants. The following are key characteristics of CWMAs/CISMAs/PRISMs:

  • Work within a defined geographic area
  • Participation from a broad cross-section of stakeholders and land owners
  • Decision making though a steering committee
  • Long-term commitment to cooperation, preferably formalized through a partnership agreement
  • Have a strategic plan for addressing species of concern
  • Coordinate across jurisdictional boundaries


CWMAs/CISMAs/PRISMs enable partners to pool resources to address invasive species problems held in common. Partnerships are more efficient and effective than piecemeal approaches. Due to these benefits, MIPN advocates for and offers technical support towards the establishment of CWMAs/CISMAs/PRISMs in the Midwest. Please explore some of our resources below.

CWMA Cookbook

The CWMA concept was initially developed in the Western U.S. In 2003, the Idaho Noxious Weed Coordinating Committee published a "cookbook," which provided a step-by-step guide explaining how to form a CWMA. MIPN adapted this work into a CWMA Cookbook for the Eastern U.S. If you are interested in forming a CWMA and would like training on the Cookbook, please contact us. A sample training presentation is provided below.

  • Interactive map of Great Lakes States CISMAs/PRISMs/CWMAs by the Great Lakes Commission
  • National CWMA Map - by the North American Invasive Species Network (NAISN)
  • PowerPoint presentations, with audio, available from The National Cooperative Weed Management Area (CWMA) Conference, April, 2008, Reno, Nevada. Click here to access. The conference focused on CWMA funding and logistics, working with volunteers, EDRR, awareness and outreach, approaches to mapping, and state and national initiatives. In addition to enjoying 27 talks by speakers from across the U.S., attendees from 37 states provided glimpses of cooperative weed management activities in their own states.
  • 2019 Land Manager's Guide to Developing an Invasive Plant Management Plan prepared by U.S. Fish & Wildlife Service's Pacific Southwest Region, Inventory and Monitoring Initiative, and the California Invasive Plant Council  to assist in the planning process and focus limited resources toward the greatest conservation benefit.
  • Site Revegetation Resources prepared by MIPN with support from the U.S. Forest Service to help improve the long-term effectiveness of invasive plant control efforts.
