Aquatic Invasive Species
Not Just for Watercrafts!
For more information on Aquatic Invasive Species in Montana – AIS-Montana
Aquatic Invasive Species (AIS) – Plants, animals, or pathogens that are not native to Montana and can cause harm to our environment and economy.
- Why are they dangerous?
- They 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 cause wildlife and public health problems.
- How do I prevent them from spreading?
- Clean – Completely remove all mud, water and vegetation before leaving access area.
- Cleaning will remove visible large-bodied organisms attached to or in watercraft or recreational equipment.
- Water at least 120°F is recommended; be sure to avoid contact with skin and check manufacturers’ recommendations to ensure equipment can withstand high temperatures.
- Drain – All water from watercraft and equipment.
- Dry – Your watercraft and equipment. Aquatic invaders can survive only in water and wet areas.
- Dry your watercraft and fishing equipment thoroughly; this will kill most invasive species. The longer you keep your watercraft, trailer, waders, and other equipment outside in the hot sun, the better.
- Drying is necessary as many organisms can survive in standing water.
- Dry in the sun (drying times will vary) or use a towel.
- Clean – Completely remove all mud, water and vegetation before leaving access area.
- What is Montana doing to stop the spread?
- Boat Inspection Stations
