  • Noxious Weed Identification and Control by List or Color

     

    Colorado is seeing a dramatic increase in noxious weeds. Left uncontrolled, noxious weeds will form dense monocultures and displace native and desirable plants. Native plant loss affects wildlife that depends on the native vegetation for survival.

    Please select from the following categories, by list or color, to find detailed information on the weed in which you’re interested.
