Rangeland Weeds

Day 3 — Rangeland Weeds

What is a rangeland? Rangelands host native vegetation, predominantly grasses, grass-like plants, forbs, or shrubs, that provide forage and cover for wildlife and domestic livestock, high-quality water, open space, and recreational opportunities (USDA). In Montana, rangelands make up about 70% of our 93-million acres (MSU).

Unfortunately, noxious weeds can have a significant impact on our rangelands. For Day 3 of MNWAW, we are sharing resources about rush skeletonweed, spotted knapweed, and leafy spurge. Each has different characteristics that effect our rangelands. Use these resources to learn something new and/or as a way to promote and distribute information to your constituents, family, friends, and neighbors.
