Forest Weeds

Day 6 – Forest Weeds

How many weeds are listed on the State of Montana’s noxious weed list? Montana Department of Agriculture has 36 noxious weeds that are to be managed across the state. Montana also has 11 National Forests, totaling ~17-million acres. For Day 6 of MNWAW, we will learn about four forest weed species: Tansy ragwort, Houndstongue, and Hawkweeds. Use these resources to learn something new and/or as a way to promote and distribute information to your constituents, family, friends, and neighbors.
