Noxious Weeds

Invasive plant species have been cited as the second-largest threat to endangered native plant species.  Most noxious plant species in New Mexico are found on rangelands and wild lands. These invasions result in decreased forage availability for livestock and wildlife. To reverse and prevent these impacts, the New Mexico Department of Agriculture coordinates weed management among local, state, and federal land managers, as well as private landowners. The Noxious Weed Management Act directs NMDA to develop a noxious weed list for the state, identify methods of control, and educate the public about noxious weeds. 

The New Mexico Department of Agriculture's noxious weed dashboard provides a platform for tracking invasive plant species across New Mexico. The dashboard integrates publicly available data from state, federal, local, tribal, nonprofit, and private partners into a single Geographic Information System, giving land managers, researchers, and the public access to noxious weed observations, management activities, and other relevant spatial datasets.

The NMDA Noxious Weed dashboard has continued to expand through contributions from partners across the state, improving our understanding of invasive species distributions and supporting coordinated, data-driven management efforts. These data are made accessible to help users identify priority areas, monitor treatment activities, and make informed decisions to protect New Mexico's natural resources and agricultural lands.

You can help improve this resource by reporting noxious weed sightings through the EDDMapS mobile app (available for Android and iOS) or by submitting observations online through the EDDMapS website.

NMDA's Noxious Weed Management Grant

The application period for the NMDA Noxious Weed Management Grant is currently closed. Information about the next funding opportunity, including eligibility requirements, application deadlines, and updated program guidance, will be posted here when it becomes available. Please check back for updates.

New Mexico’s Cooperative Weed Management Areas

Cooperative Weed Management Areas (CWMAs) are partnerships of government agencies, tribes, various groups, and individuals that manage noxious weeds and/or invasive plants.  Many CWMAs provide technical assistance, equipment, and educational opportunities related to noxious weed identification and management. Contact your local CWMA to learn how you can participate in the management of noxious weeds and invasive plants in New Mexico.
