Day 2 – Invasive Annual Grasses
What are invasive grasses? Invasive grasses are noxious weeds that have the significant potential to be detrimental to agriculture, the economy, and the environment. The Montana Department of Agriculture has four invasive grasses identified on the state noxious weed list. Ventenata (2A), Medusahead (1A), and Phragmites (1A) are state listed, and Cheatgrass (3) is state regulated.
For Day 2 of MNWAW, we will be learning about the three invasive annual grasses, Ventenata, Medusahead, and Cheatgrass. Use these resources to learn something new and/or as a way to promote and distribute information to your constituents, family, friends, and neighbors.
