The NAS database tracks the distribution of introduced aquatic organisms across the United States. The publicly accessible information repository monitors, records, and analyzes reported sightings for >1,300 species like lionfish, zebra mussels, and hydrilla. The database contains observations from as early as 1800, derived from many sources, including scientific literature; federal, state, and local natural resource monitoring programs; museum collections; news agencies; and direct submission through on-line reporting forms from citizen scientists.
