Cooperative Weed Management Areas

Communities of landowners are joining with local, state, and federal partners to prevent and manage invasive plants and support healthy ecosystems by organizing cooperative weed management areas (CWMAs) across the United States.

CWMAs may have different names in different parts of the country - for example, Partnerships for Regional Invasive Species Management (PRISMs) in New York or Cooperative Invasive Species Management Areas (CISMAs) in Florida.
