The Larimer County Weed District is responsible for noxious weed management in the unincorporated areas of the county as mandated by the Colorado Noxious Weed Act and outlined in the Larimer County Noxious Weed Management Plan.
Colorado Noxious Weed Act
The Colorado Noxious Weed Act states that noxious weed management is the responsibility of local governing agencies: incorporated municipalities, counties and lands owned by state agencies. The Act stipulates that the board of county commissioners of each county in the state shall adopt a noxious weed management plan for all the unincorporated lands within the county. The Larimer County Noxious Weed Management Plan was approved by the Larimer County Board of County Commissioners on December 19, 2023. Larimer County, in cooperation with the Colorado Department of Agriculture, Colorado State University Cooperative Extension and other agencies, actively promotes compliance with the Noxious Weed Act. The County will enforce the Act's provisions on non-compliant landowners.
- The Larimer County Noxious Weed Management Plan requires eradication of all List A species and infestations of certain List B species identified as regionally scarce by the state. The plan requires containment and suppression measures for List B species that are abundant in the county.
- Enforcement as outlined in Larimer County's weed plan cannot be enacted on private or public property without first applying the same measures to any land or rights-of-way owned or administered by the County that are adjacent to such properties.
