Aquatic Invasive Species

What are Aquatic Invasive Species (AIS)?
AIS are non-native plants or animals introduced into waterbodies that have the potential to harm the environment, people, and the economy. Click here for more details.

Why you should care
Nearly two-thirds of all endangered fish and clams have been impacted by invasive non-native species. Hydropower facilities, municipal water supplies, the aquaculture industry, and agricultural irrigation can also suffer tremendous losses from these invaders.

AIS cause an estimated $123 billion dollars in damage annually in the United States!

What the Service is doing about it
Our agency co-chairs the Aquatic Nuisance Species Task Force. We coordinate with federal agencies and partners to prevent and control aquatic invasive species, and provide expertise and support for action-oriented partnerships.

Our collaboration with partners
We work with the Western Regional Panel to prevent the western spread of quagga and zebra mussels. We also provide funding to Oregon, Washington, Idaho, and Hawaii to help implement statewide aquatic nuisance species plans and fund research on aquatic invasive species prevention and nuisance control.
