United States - Individual States

Provides lists and information for species declared invasive, noxious, prohibited, or otherwise harmful or potentially harmful. Information is provided for each state, organized alphabetically by organization.

Refer to our main Invasive Species Lists page for general resources relevant to the U.S., including regional and multi-state resources, as well as International information.

In the U.S., there are many Federal agencies and State agencies involved with regulating invasive species, and unfortuntately there is no accepted standard for regulating all types of invasive species in all geographic areas.

We have included the following resources for information purposes only and should not be considered complete, or legally binding. Resources included may not have current information based on the current regulations. For further information pertaining to actual regulations, please see our Laws and Regulations section to find information directly from the regulating agencies. Each State has different statutes and administrative rules that may dictate its role in the management of invasive species.

Note: Resources marked with an ** designate legal authority.
