Aquatic Invasive Species

Help protect Montana's waters

AIS can be easily spread from one waterbody to the other. Anglers, boaters, construction workers, pond owners, gardeners, seaplane pilots, field workers - virtually anyone who works or plays in or around water can unknowingly transport these pests on their boats and equipment. It takes only one mistake to potentially infest a new water body.

Prevent the spread of AIS
