Why Should I Report Invasive Species?

Reporting suspect and/or invasive species is very important! Monitoring and reporting is an important part of controlling invasive species in Park County. Monitoring can identify new populations of invasive species while they are still small and able to be managed.


In Montana, where you report invasive species depends on what kind of plant or animal they are, so that the correct agency can respond to your report. Find out where to report invasive species below.

If you see or suspect a new infestation of an aquatic invasive species (such as fish, mussels, or aquatic weeds), please save a specimen and complete a Report a Suspected AIS form. You can also notify the FWP Fisheries office at (406) 444-2440.

Report potential violations relating to mandatory watercraft inspections and the certified boater program to TIP-MONT (406) 847-6668.

Report noxious weeds (such as trees, shrubs, flowers, and grasses) in Montana to the EDDMapS app.

Tree pests (insects or diseases found in or on trees) in Montana are managed by multiple agencies, depending on land ownership. Report suspect tree pests to the Montana Department of Agriculture or your county extension agent.

The Park County extension office can be contacted at park@montana.edu or (406)-222-4156.

Feral hogslivestock diseases, and escaped non-native animals are managed by the Montana Department of Livestock. Report suspect feral hogs to (406) 444-2976.

To report other suspect invasive species, that don’t seem to fit in the categories above, please contact the Montana Invasive Species Council.


Invasive species of any kind can also be reported at inaturalist.org online or in the mobile app.
