When a new species is introduced, the best strategy is Early Detection and Rapid Response. This includes monitoring habitats to discover new species soon after introduction, reporting sightings of previously unknown species in an area, and working quickly to keep the species from becoming established and spreading. EDRR can slow range expansion of ANS, and avoid the need for costly long-term control efforts. Below are key resources developed by the Aquatic Nuisance Species Task Force, its members, regional panels, or subcommittees to detect and response to aquatic nuisance species before they establish and cause harm:
Nonindigenous Aquatic Species (NAS) information resource (U.S. Geological Survey) - a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, distribution maps, and general information.
Great Lakes Aquatic Nonindigenous Species information System (NOAA Great Lakes Environmental Research Laboratory) - a regional node of the USGS Nonindigenous Aquatic Species (NAS) database, provides information about aquatic nonindigenous species in the Laurentian Great Lakes region of North America
Lake Champlain Basin Rapid Response Action Plan for Aquatic Invasive Species- intended to ensure and facilitate the availability of appropriate protocols, trained personnel, equipment, permits, and other resources to contain and potentially eradicate newly detected nonnative aquatic invasive plant, animal, and pathogen introductions as they are reported or discovered in the basin.
