Native Plants and Noxious Weeds

Support Native Growth. Stop Invasive Spread.

Montana’s native plants shape the state’s landscapes and sustain wildlife, soil, and water systems. Noxious weeds threaten that balance by spreading quickly and crowding out the plants ecosystems depend on. Protecting native growth helps preserve the land, wildlife, and working landscapes that make Montana extraordinary.

5 Practical Ways to Make a Difference

  1. Learn what belongs—and what doesn’t.
    Being able to recognize common native plants and a few high-priority weeds makes early action possible, when control is simplest and most effective.
  2. Choose native and weed-free materials.
    Native plants are adapted to Montana’s climate and support wildlife, while certified weed-free seed, hay and straw prevent new infestations.
  3. Clean gear, vehicles and equipment.
    Weed seeds travel easily on tires, boots and tools. Cleaning between locations is one of the most effective ways to stop spread.
  4. Act early and report new sightings.
    Small patches are far easier and less costly to manage than established infestations. Reporting unfamiliar plants helps catch problems early.
  5. Support local restoration efforts.
    County weed districts and community projects play a key role in protecting shared land. Getting involved strengthens both ecosystems and communities.

Why This Matters

Native plants support wildlife, stabilize soil, and require less water and maintenance. When invasive weeds take over, habitat declines, erosion increases, and land becomes harder—and more expensive—to manage. Early, consistent action protects both natural and working landscapes.
