CISMAS / Regional Groups

Wisconsin Cooperative Invasive Species Management Areas (CISMAs)

CISMAs are local organizations that bring together landowners and land managers to coordinate action and share expertise and resources to manage invasive species. CISMAs often function under the authority of a mutually developed Memorandum of Understanding or Cooperative Agreement and are governed by a steering committee. Together, CISMA partners develop a comprehensive invasive species management plan for their area. At the least, CISMA plans include invasive surveying and mapping components as well as plans for integrated invasive species management. More comprehensive plans may include education and training, early detection of new invaders, monitoring, revegetation, and annual evaluation and adaptation of the invasive species management plan.

Locally-driven CISMAs are especially effective at generating public interest in invasive species management and organizing community groups to support on-the-ground programs. In states that do not have a long history in or strong legislative mandate for invasive species management, newly forming CISMAs are building crucial grassroots support for statewide weed management programming. 

A Cooperative Invasive Species Management Area is a partnership of federal, state, and local government agencies, tribes, individuals, and various interested groups that manage noxious weeds or invasive plants in a defined area.

There are five characteristics of CISMAs:

  • Defined geographical area distinguished by a common geography, invasive species problem, community, climate, political boundary, or land use.
  • Involvement or representation of the majority of landowners and natural resource managers in the defined area.
  • Steering committee.
  • Commitment to cooperation.
  • Comprehensive plan that addresses the management of prevention of one or more noxious weeds or invasive plants.

The Midwest Invasive Plant Network's (MIPN's) Cooperative Weed Management Area resource page may also be of interest to you.
