Serving Montana Agriculture and growing prosperity under the Big Sky

Noxious Weeds


Noxious weeds have a destructive impact on Montana's landscape by displacing native plant species, increasing soil erosion, and decreasing wildlife habitat and recreational opportunities. Rangeland, pastureland, cropland, forests, and wildlands cover 92 million acres, 98% of the total land area, in Montana. These lands are vital for agricultural production and protecting the integrity of ecosystems.

The Department's Noxious Weed Programs offer resources and assistance with the management of state- and county-listed noxious weeds.

  • Petition cycle open for new weeds to list on MT Noxious Weed List
