Noxious Weed Identification
The County Noxious Weed Control Act is enforced at local county level. The noxious weed control law establishes weed management districts throughout the state. These management districts are defined by the boundaries of the county.
Noxious weeds are non-native, invasive plant species that have been introduced into the ecosystem and displace native Montana plant species. These plants increase soil erosion, decrease wildlife habitat and recreational opportunities, and cause negative economic impacts.
If you believe you have found a noxious weed, please contact your county weed district office. We can help you with a management plan, offer best practices on control and (potential) eradication and, in some cases, provide cost-share programs to assist you with management.
To learn more about noxious weeds and noxious identification, see this resource from the Montana Department of Agriculture.
A list of the County and Statewide noxious weeds can be found here.

Plant Identification!
Plant samples for identification may be submitted in the following ways:
Collect a plant sample (root, stem and blossoms if possible), and preserve in a sealed plastic bag or other container, and bring by the Weed District office located on the south side of the fairgrounds between the county shop and the animal shelter. Please call ahead to make sure someone will be in the office to assist you: (406) 846-3348 or (406) 560-2919.
You may also submit photos via text message to (406) 560-2919. Please include close-up images of as many plant parts as possible, the location, and your contact information.
