Yellow Toadflax ("Butter and Eggs")
Town of Crested Butte Noxious Weed Program
The Town of Crested Butte is at the northern end of the Slate River Valley and at the headwaters of the Colorado River. As the “Wildflower Capital of Colorado”, the health of our natural environment is a high priority for residents of Crested Butte. The spread of noxious weeds can result in monocultures of weeds rather than the rich variety of wildflowers currently found in our valley. Noxious weeds are jeopardizing our valued ecosystems and displacing native plants. Noxious weeds spread to our downstream neighbors having a negative impact on agricultural lands and other communities. Through the support of our regional partners, the Town has an effective Weed Management Plan that is a vital component in protecting the local ecosystems that are home to some of the highest quality wetlands and greatest biodiversity in the state. The Town is grateful for our partners in weed management including Gunnison County, the USFS, the BLM, the Town of Mt. Crested Butte, Crested Butte Land Trust, Rocky Mountain Biological Laboratory, CB South POA, Crested Butte Community School, and Donna Walker.
