Invasive species have been cited as the second largest threat to endangered native species.  Most noxious species in New Mexico are found on rangelands and wild lands.  Invasions of noxious species in the range and wild landscape result in decreases in available forage for livestock and wildlife.  The Noxious Weeds Management Act directs NMDA to develop a noxious weed list for the state, identify methods of control for designated species, and educate the public about noxious weeds.  NMDA coordinates weed management among local, state, and federal land managers as well as private land owners.

New Mexico’s Cooperative Weed Management Areas


Over the past 2 years New Mexico has seen a dramatic increase in the number of Cooperative Weed Management Areas (CWMAs) throughout the state. This growth has been in response to the increasing threat that New Mexico is facing from Noxious Weeds. These non-native plant species are extremely invasive and are having tremendous impacts on New Mexico’s natural and economic resources. CWMAs are a partnership of federal, state, and local government agencies, tribes, individuals, and various interested groups cooperating to manage noxious weeds or invasive plants in their area.
