Why Control Noxious Weeds
Invasive noxious weeds have been described as a raging biological wildfire – out of control, spreading rapidly, and causing enormous economic losses. Millions of acres in North America have been invaded or are at risk of being invaded by weeds, including cropland, pastures, rangelands, forests, wilderness areas, national parks, recreation sites, wildlife management areas, transportation corridors, waterways, wetlands, parks, golf courses, even yards and gardens. Noxious weeds are currently spreading at a rate of more than 4,600 acres per day on federal lands in the United States.
Devastation caused by noxious weeds is enormous. Economic losses from weeds exceed $20 billion annually in the United States, and the cost continues to grow. Weeds often reduce crop yields, and can damage watersheds, increase soil erosion, negatively impact wildland plant and animal communities, and adversely affect outdoor recreation. Ecological damage from uncontrolled noxious weed infestations can be permanent, leaving lands unable to return naturally to their pre-invasion condition.
Prevention, preserving and protecting lands not presently infested, is the first line of defense against aggressive noxious weeds. Prevention requires awareness and action by land managers as well as the general public, to recognize, report, and control new infestations before they have a chance to expand and spread.

Noxious Weed Alert
The primary purpose of this Early Detection, Rapid Response (EDRR) Noxious Weed Alert page is to enable citizens to report new, typically small, infestations of state, county or other noxious or invading weeds. There are many small, often undiscovered, infestations of harmful invasive weeds that need to be mapped and controlled. If you know of any such infestations of plants you have not noticed in an area before or that “don’t look like they belong,” please go to EDDMapS.org to report your weed sighting.
Reporting is very easy by downloading the EDDMapS West App from the App store to your phone. From the app, You can see all the weeds that have been reported and every weed you enter will be reported to the appropriate agency. You may also contact your local Weed Department.
EDDMapS will help you and weed control authorities stay ahead of the invasive weeds in your area. EDRR is vital to effective weed control because small patches of invading weeds are typically much easier to control than well established patches are. Thank you for your help in discovering, reporting and controlling these harmful invasive weed species.
We need phragmites data
Please share your phragmites mapping data and send it to Patti Sutton at USDA. Any GPS data points with associated patch size or a simple google map with hand drawn circles where phragmites is located and rough estimate of acres would be helpful.
Utah's Noxious Weed List
The State of Utah recently updated its noxious weed list. As of 2021, Utah lists a total of 54 weeds on the noxious weed list. Additionally these weeds have been newly classified into the following five categories:
1A = Not known to exist in Utah. Significant risk of invasion.
1B = Limited distribution in Utah. EDRR (Former A Class)
2 = Widely distributed in Utah, considered controllable (Former B Class)
3 = Widely distributed in Utah, considered beyond control, control expansion (Former C Class)
4 = Present in Utah. Prevent distribution through Seed law
*Each county in Utah may have different priorities regarding specific State designated Noxious Weeds and therefore may reprioritize these weeds as they see fit for their own needs.
