Aquatic Invasive Species (AIS) are plants, animals or pathogens that are not native to Montana and can cause harm to our environment and economy.

AIS are introduced accidentally or intentionally outside of their native range. AIS populations can reproduce quickly and spread rapidly because there are no natural predators or competitors to keep them in check. AIS can displace native species, clog waterways, impact irrigation and power systems, degrade ecosystems, threaten recreational fishing opportunities and can cause wildlife and public health problems.

If you plan to recreate on Montana’s waterways, know:

  • What AIS inspections are required if you bring your own boat.
  • If you use a watercraft of any kind (motorized and nonmotorized) while here, follow three simple steps: Clean.Drain.Dry
