Noxious Weed Mitigation Resources

The Colorado Department of Agriculture and Boulder County have identified invasive, noxious weeds that pose an economic and environmental threat to our State.

In accordance with the Lyons Municipal Code (Sec. 7-5-30), it is unlawful for any any owner, lessee, agent, occupant or person in possession or control of any lot or tract of land to allow any brush, weeds, local noxious weed or state noxious weed. 
As such, it is the noted individual's responsibility to eliminate noxious weeds. 

Boulder County and State of Colorado has observed numerous areas of Myrtle Spurge and other noxious weeds, within the Town of Lyons. Eradication of State List A Noxious Weed Species is necessary for the health of native species. The Town of Lyons works closely with the County, and action toward compliance is in full force. Be advised compliance with the Colorado Noxious Weed Act, Boulder County Noxious Weed Plan, and Town of Lyons is not optional. Failure to comply may result in legal action and abatement action taken by the Town. Abatement costs incurred by the Town will be billed to the property owner or collected as liens against the property (Lyons Municipal Code (Sec. 7-5-30).

Myrtle spurge is a tap rooted perennial that can reproduce by seed or plant fragments. Myrtle spurge is an escaped ornamental, found in small patches. This plant contains a toxic, milky sap which can cause severe skin irritations, including blistering. Myrtle spurge is poisonous if ingested; causing nausea, vomiting and diarrhea.  Wearing gloves, long sleeves, shoes, and eye protection is highly recommended when in contact with all plant parts.
