TopNoxious Weeds
Noxious weeds threaten the very reason we live, work, and recreate in Colorado. Noxious weeds are not native to the United States and they are highly competitive and persistent. These weeds become invasive because they grow unchecked by natural predators and enemies such as insects or diseases. It is very important to get control of these invasive species on a local level before they become widespread. If left uncontrolled, infestation levels will continue to intensify and control will be increasingly difficult and expensive for everyone. We must stop these detrimental plants from further damaging both public and private lands. Everyone must do their part.
TopNoxious Weed Management
Noxious weed management is the systematic approach to minimize noxious weed impacts and optimize intended land use. It is very important for all infested areas to be treated with effective methods. Integrated management is a program of noxious weed control that properly implements a variety of coordinated control methods. Types of control methods include mechanical, cultural, chemical, and biological. Integrated management greatly improves the success rate for your weed control plan. All noxious weed management must be applied and evaluated over an extended period of time to be successful.
TopDefinition of a Noxious Weed in the State of Colorado

Noxious Weed Management Plan for the Unincorporated Areas of Pueblo County, Colorado
It is the intent of this plan to allow land managers every opportunity and resource to alleviate weed infestation problems without government intervention while still protecting the body of the citizenry from the impacts of noxious weed infestations.

TopColorado Noxious Weed Act
Colorado Noxious Weed Act (C.R.S. §35-5.5-101 to §35-5.5-119)
Rules Pertaining to the Administration and Enforcement of the Colorado Noxious Weed Act (8 CCR 1206-2)
TopColorado Noxious Weed List and State Noxious Weed Management Plans
- List A weed species in Colorado are designated by the Commissioner of Agriculture for eradication.
- List B weed species are species for which the Commissioner of Agriculture, in consultation with the state noxious weed advisory committee, local governments, and other interested parties, develops and implements state noxious weed management plans designed to stop the continued spread of these species.
- List C weed species are species for which the Commissioner of Agriculture, in consultation with the state noxious weed advisory committee, local governments, and other interested parties, will develop and implement state noxious weed management plans designed to support the efforts of local governing bodies to facilitate more effective integrated weed management on private and public lands. The goal of such plans will not be to stop the continued spread of these species but to provide additional education, research, and biological control resources to jurisdictions that choose to require management of List C species.
TopThe Upper Arkansas Cooperative Weed Management Area
The purpose of the Upper Arkansas CWMA is to form partnerships in order to raise awareness of noxious weeds through education and to identify, contain, and control the spread of noxious weeds throughout the upper Arkansas River watershed region. The Upper Arkansas CWMA's mission is to develop and implement a coordinated strategic weed management plan involving a partnership between counties and associated municipalities, state and federal agencies, private citizens and organizations to implement an integrated weed management effort using all available methods and to coordinate, prioritize, and direct the efficient use of resources to protect, manage, and enhance plant and animal communities.
