U.S. Geological Survey Nonindigenous Aquatic Species program The U.S. Geological Survey Nonindigenous Aquatic Species program provides surveillance, data aggregation, and risk assessment for invasive species in United States waterways, coordinating with federal, state, and tribal partners to document introductions of fishes, crustaceans, mollusks, and aquatic plants. The program supports decision-making for agencies including the U.S. Fish and Wildlife Service, National Oceanic and Atmospheric Administration, and state fish and wildlife agencies through geospatial mapping, occurrence records, and technical guidance. It integrates observations from academic institutions such as the University of Florida, conservation organizations like The Nature Conservancy, and museum collections including the Smithsonian Institution to inform management and policy.

Overview

The program maintains a national information system that catalogs nonindigenous aquatic species occurrences across Great Lakes, Mississippi River, Chesapeake Bay, and coastal ecosystems, linking specimen records from institutions such as the Florida Museum of Natural History, Smithsonian National Museum of Natural History, and universities including University of Michigan, Louisiana State University, and Oregon State University. It provides mapping and risk-assessment tools used by agencies including the Environmental Protection Agency, Army Corps of Engineers, and state departments such as the Florida Fish and Wildlife Conservation Commission and California Department of Fish and Wildlife. The program’s resources are cited in management plans by entities including United States Geological Survey, National Park Service, Bureau of Land Management, and international bodies like the International Maritime Organization.

History and Development

Origins trace to specimen cataloging and outreach efforts by the U.S. Fish Commission and early Bureau of Fisheries collections, with expansion through partnerships with academic researchers from the University of Florida and Gainesville museums. Formalization in the 1990s occurred amid increased attention from policymakers in the U.S. Congress and federal initiatives addressing ballast water after consultations with National Research Council committees and directives influenced by incidents such as Zebra mussel invasions in the Great Lakes. The program evolved alongside legislation and programs including work by the National Invasive Species Council, consultations with the Smithsonian Institution, and cooperative projects supported by the Gulf of Mexico Research Initiative.

Data Collection and Monitoring

Data sources include field observations from state agencies such as the Michigan Department of Natural Resources and Minnesota Department of Natural Resources, university research programs at institutions like Cornell University and University of Washington, museum specimen data from Field Museum and American Museum of Natural History, and citizen science inputs coordinated with platforms such as projects run by Smithsonian Environmental Research Center and networks affiliated with Sea Grant. Monitoring emphasizes taxa of concern including Asian carp, Zebra mussel, Lionfish, and Hydrilla, with occurrence data used by federal responders at NOAA Fisheries and state invasive species councils. Surveillance methods incorporate trawl surveys used by National Marine Fisheries Service, eDNA techniques developed in laboratories at Woods Hole Oceanographic Institution and Scripps Institution of Oceanography, and visual encounter protocols shared with conservation NGOs like Monterey Bay Aquarium.

Database and Mapping Tools

The program’s database aggregates georeferenced records and integrates with mapping platforms used by the U.S. Geological Survey and partners including GIS systems from Esri clients and state geospatial portals such as Florida Geographic Data Library. Interactive mapping tools allow users from agencies including the Army Corps of Engineers and researchers at University of California, Davis to visualize spread pathways in basins like the Missouri River and estuaries such as the Delaware Bay. The system supports data exports used in models developed at institutions like Princeton University and University of Maryland, and informs regulatory analyses by the Environmental Protection Agency and economic assessments by U.S. Department of Agriculture analysts.

Research and Publications

Staff and collaborators publish occurrence analyses, risk assessments, and methodological papers in journals and outlets associated with National Academy of Sciences committees, universities including University of Florida and Michigan State University, and international forums such as meetings of the International Union for Conservation of Nature. Research topics include invasion pathways studied alongside experts from Rutgers University and Texas A&M University, eDNA validation work with Woods Hole Oceanographic Institution, and impact assessments referenced by policy reports from the National Oceanic and Atmospheric Administration and National Research Council.

Outreach, Partnerships, and Policy Impact

The program conducts outreach with state invasive species councils, tribal resource managers, and NGOs such as The Nature Conservancy and World Wildlife Fund USA to support rapid response and prevention planning. It informs policy decisions by the U.S. Congress and federal rulemaking at agencies like NOAA and the Environmental Protection Agency, and supports international exchange with bodies such as the International Maritime Organization and regional partnerships in the Great Lakes Commission. Training and workshops involve universities including University of Florida and Clemson University and liaison with aquaculture stakeholders represented by organizations like the National Aquaculture Association.

Limitations and Criticisms

Critiques of the program focus on data completeness and reporting lags compared to modeled distributions developed at Princeton University and University of California, Davis, interoperability challenges with state databases used by the California Department of Fish and Wildlife and Florida Fish and Wildlife Conservation Commission, and constraints noted by panels convened by the National Research Council. Other limitations cited include uneven taxonomic coverage compared to museum collections at the American Museum of Natural History and funding and staffing pressures documented in reviews by the Government Accountability Office and analyses by academic partners at University of Michigan.
