Aquatic Nuisance Species (ANS) Task Force- Begun in 1990, this agency is charged with coordinating efforts to prevent detrimental effects from nonindigenous species.
Aquatic Nuisance Task Force- Information on aquatic introduced species. Did you know that about 400 of the 958 (42 percent) species listed as threatened or endangered under
the Endangered Species Act are considered to be at risk primarily because of competition with and predation by non-indigenous species.
Invasive Species- Information on introduction of exotic species, both aquatic and terrestrial, associated governmental agencies, and links, from the National Biological Information Infrastructure.
Sea Grant Nonindigenous Species Site- Nonindigenous (e.g. non-native) species can be clicked on for more information. Most species are freshwater species, such as those introduced to the North American Great Lakes.
