Noxious weeds can increase soil erosion which can adversely affect water quality for fish, and thick stands of noxious weeds such as salt cedar or Russian olive, can make access to rivers and streams difficult.

Noxious weeds can invade pastures and range land reducing viability. Weed seeds can be transported in the fur of livestock and in manure. Even more importantly, many of Montana state-listed weeds are toxic to animals.

Noxious weeds can negatively affect the value of your property. Be a responsible landowner and follow the law by managing and preventing noxious weeds on your property.

Noxious weeds adversely affect the habitat where game and waterfowl reside. While hunting, your clothing, vehicles and dogs can transport weed seeds impacting future hunting opportunities.
