Noxious weeds found in Montana include leafy spurge, knapweed, and dalmatian toadflax. To avoid spreading these weeds:
- Do not ride through weed patches.
- Wash your OHV after every outing to make sure it is clean and free of weed seeds.
- Let the landowner or manager know if you find a weed-infested area so that they can take action to control the weeds.
