County Weed Programs
The Colorado Department of Agriculture works closely with the state’s 64 counties to manage noxious weeds. State Noxious Weed Management Plans are developed with the use of mapping information provided by the counties, and each plan is discussed and finalized with their participation. Local weed management information can be obtained from County Weed Managers and Coordinators displayed in the Google map below.
The Department appreciates the counties’ efforts to educate and effectively lead weed control efforts throughout the state.
Below is a Google map of Colorado with contact information on each County Weed Program. Should you have any questions please feel free to contact Noxious Weeds.
Colorado List B Weed Management Plans by Counties
The state Noxious Weed Act directs the Department of Agriculture to develop and implement management plans for all List A and List B species. For List B species, these plans identify management objectives that specify timelines for elimination and strategies for managing populations that will result in stopping the spread of List B plant populations.
“Elimination” means the removal or destruction of all emerged, growing plants of a population of List A or List B species designated for eradication by the Commissioner. It is the first step in achieving eradication and is succeeded by efforts to detect and destroy newly emerged plants arising from seed, reproductive propagule, or remaining root stock for the duration of the seed longevity for the particular species.
"Containment" means maintaining an intensively managed buffer zone that separates infested regions, where suppression activities prevail, from largely uninfested regions, where eradication activities prevail. Containment map figures (effective 12/30/15).
"Suppression" means reducing the vigor of noxious weed populations within an infested region, decreasing the propensity of noxious weed species to spread to surrounding lands, and mitigating the negative effects of noxious weed populations on infested lands. Suppression efforts may employ a wide variety of integrated management techniques.
