Aquatic Invasive Species


The Montana Department of Natural Resources and Conservation (DNRC) offers state-funded grants for the prevention and control of aquatic invasive species (AIS). The goal of the grants is to protect the natural resources of Montana from severe and unacceptable damage from aquatic invasive species.

Quagga Mussel

The proposed project must be critical and urgent and contribute to the protection of Montana’s environment from severe and unacceptable damage to natural resources from aquatic invasive species. 

Public benefit from implementation of the project must directly relate to the prevention and/or control of aquatic invasive species. Preference will be given to priority waters, as well as to on-the-ground projects such as surveys and removal that result in measurable control of aquatic invasive species.

Priority Species:

Preference will be given to species on the Montana Noxious Weed List (  and to zebra/quagga mussels.


Examples of projects include:

  • Baseline survey 
  • Monitoring
  • Education and outreach
  • Planning, e.g. management plan
  • On-the-ground control

To see examples of previously funded projects, see AIS funded projects here.
