Aquatic Invasive Species

Aquatic invasive species are marine, estuarine, or freshwater organisms that invade ecosystems beyond their natural, historic range. They cause economic and environmental damage as well as detrimentally affect human use of our natural resources by permanently degrading the habitats they invade, hindering economic development, reducing or eliminating recreational and commercial activities, decreasing the aesthetics of our environment, and serving as vectors of disease.


This website reflects the collaborative efforts of many states and provinces in the western United States and other regions of the country to prevent the introduction and spread of aquatic invasive species by focusing on their pathways of introduction, sharing information and best management practices, achieving consensus on protocols and standards as well as regulations, developing and implementing outreach campaigns to raise public awareness, and providing training. A network of committed individuals, agencies, and organizations are working together to advance our understanding of the detrimental effects of invasive species and reduce the effects they have on us, our environment, and our economy.


We encourage you to use this website to understand what you need to know if you are moving a boat, seeking watercraft inspection and decontamination training, want to understand the regulations that exist in different states and provinces, seek to learn the latest news about aquatic invasive species, or would like to review any of our interactive online databases, such as how and where biologists are monitoring for the presence of aquatic invasives, or what rapid response plans exist to address a new introduction of aquatic invasives, If you missed one of the webinars in our webinar series, you can review the recordings here.


Our thanks to everyone for the level of cooperation and collaboration that takes place on a daily basis to make the information on this website possible.



Prevention is the first line of defense.

Everyone can make a difference in the fight against invasive species by learning about how to prevent their movement.

Boat Owners: Clean, Drain, and Dry
Anglers: Inspect and clean your gear, dispose of bait properly, and never move live fish from one body of water to another.

Pet Owners: Never release aquarium fish and plants, live bait or other exotic animals into the wild, don't dump your aquarium water into natural habitats, and make responsible pet purchases.

Outdoor enthusiasts: Inspect and remove mud from boots, gear and vehicle, and recognize and report invasives.
