Nonindigenous Aquatic Species (NAS)

A database developed by the United States Geological Service (USGS)

The NAS information resource website is developed and maintained by the United States Geological Service (USGS).

You can find the Nonindigenous Aquatic Species (NAS) website here: https://nas.er.usgs.gov/default.aspx

Summary

The NAS database is an established central information resource for spatially referenced biogeographic accounts of introduced aquatic species. The NAS website provides scientific reports, real-time queries, spatial data sets, distribution maps, fact sheets, and other general information about nonindigenous aquatic species.

This data repository is highly interactive in that it provides information management using geographic information system (GIS) technology as well as occurrence detection and reporting obtained from a variety of sources such as researchers, field biologists, fishermen, and others involved in activities in the aquatic environment. You can use this database to view reported sightings that may impact concerns for management in different regions throughout the US. Additionally, you can receive timely reporting of possible new nonindigenous aquatic species and prompt dissemination of confirmed reports about the presence, or changes in distribution.

Three Things to Try with this Tool

• Use the NAS database to find an aquatic species present in your state/county that interests you. Next, view the point map to see its current spatial distribution as well as the animated map to see its spread over time!

• Sign up for the NAS Alert System! This can be tailored to your specific needs and location.

• Check out the Flood and Storm Tracker (FaST) maps to see where indigenous species have the potential to spread due to storm surge and flooding.

Utility for Management

• Search your local area for the exact locations of sightings and sign up for alert notifications when new sightings of nonindigenous species appear in your area

• View the spatial distribution of nonindigenous species surrounding the specific management area. This might be useful to anticipate future the movement of nonindigenous species into your management area.

• The excellent maps could be useful in education and outreach efforts.
