Early Detection, Rapid Response Program

The Early Detection, Rapid Response Program coordinates specific task force groups responsible for implementing Early Detection and Rapid Response tactics to prevent, or contain and control any reported infestations of high priority new invader noxious weeds and assist in the collaboration of efforts across the state and areas of infestation.

One way the MT EDRR program helps to stop the spread of high priority noxious weeds is through education, including by way of webinars presented every spring and fall. The Spring ’25 webinar, held in July, covered an overview and update on several invader species and included Dr. Joe Ikley, NDSU speaking on Palmer Amaranth and Waterhemp. It can be viewed anytime on YouTube.

These weeds are not present or have a limited presence in Montana.

These weeds are common in isolated areas of Montana or aren’t abundant in many counties.
