This field guide is designed to help you identify Montana’s 35 state listed noxious weeds and regulated plants. Each plant review includes the photos and the 10 characteristics defined to your right.
If you believe you have found a noxious weed, please contact your county weed district or tribal area office. They can help you with a management plan, offer best practices on control and eradication and, in some counties, they provide cost-share programs to assist you with management.
