Noxious Weeds

The Town of Lyons works in collaboration with the Colorado Department of Agriculture (CDA) and Boulder County to eradicate invasive species of noxious weeds throughout Lyons, Boulder County and the entire State of Colorado, and we need your help. Although there are many species on CDA’s list of noxious weeds, there are two specific species that the Town is focusing on at this time: Myrtle Spurge and Mediterranean Sage. These species have been located in and around Lyons, and we hope to work with our residents to help control these weeds that pose an economic and environmental threat to our State.
