Nonindigenous Aquatic Species (NAS)

The Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey (USGS), located at the Center for Aquatic Resource Studies, has been established as a central repository for accurate and spatially referenced biogeographic accounts of nonindigenous aquatic species. Through the site you can obtain information, maps, or search the NAS database for information about different nonindigenous aquatic species.

USGS Nonindigenous Aquatic Species Alerts
NAS Alerts
These are the 10 most recent Alerts provided by the USGS NAS. The US Geological Survey�s Nonindigenous Aquatic Species (NAS) Alert system is based on the NAS database (http://nas.er.usgs.gov), a database of locations of introduced aquatic species nationwide. An alert is generated when a species is found in a new state, county, or drainage where it has not previously been recorded. Users can view an archive of past alerts, or register to receive alerts either by e-mail or RSS, at http://nas.er.usgs.gov/AlertSystem

National Framework for Early Detection, Rapid Assessment, and Rapid Response to Invasive Species

Welcome to the National Early Detection, Rapid Assessment, and Rapid Response Framework prototype developed and hosted by the National Biological Information Infrastructure (NBII) Invasive Species Information Node.

This Framework prototype consists of six main components:

  • A. Identification and Validation
  • B. Reporting
  • C. Expert Verification
  • D. Occurrence Databases
  • E. Rapid Assessment
  • F. Planning
  • G. Rapid Response

Each component of the National ED/RA/RR Framework prototype describes an activity associated with addressing the invasive species issue and provides access to resources reported in the National EDRR Needs Assessment Survey initiated in 2006. Additional resources cataloged by the NBII are also supplied.

The NBII Program is administered by the Biological Informatics Office of the U.S. Geological Survey
