Fact Sheet 2012–3100
The U.S. Geological Survey (USGS) Nonindigenous Aquatic Species (NAS) Program monitors, analyzes, and records sightings of non-native (introduced) aquatic species throughout the United States. The program is based at the USGS Southeast Ecological Science Center in Gainesville, Florida.
The initiative to maintain scientific information on nationwide occurrences of non-native aquatic species began with the Aquatic Nuisance Species Task Force, a group created by Congress in 1990 to address the need for this type of information by natural resource managers. Since then, the NAS program has maintained the database as a clearinghouse of information for confirmed sightings of non-native aquatic species throughout the Nation. The program also produces email alerts, maps, summary graphs, publications, and other information products to support natural resource managers.
