We are working to incorporate environmental DNA (eDNA) data into the Nonindigenous Aquatic Species (NAS) database, which houses over 570,000 records of nonindigenous species nationally, and already is used by a broad user-base of managers and researchers regularly for invasive species monitoring. eDNA studies have allowed for the identification and biosurveillance of numerous invasive and threatened species in managed ecosystems. Managers need such information for their decision-making efforts, and therefore require that such data be produced and reported in a standardized fashion to improve confidence in the results. As we work to gain community consensus on such standards, we are finalizing the process for submitting...

Environmental DNA (eDNA) testing allows for high sensitivity monitoring efforts of cryptic species in large, remote systems and is performed by investigating water and soil samples for sloughed DNA. Having access to eDNA datasets across multiple taxa and ecosystems is necessary for improved coordination among researchers and management. Additionally, quality control protocols are needed to vet incoming database submissions. We developed a mechanism to submit eDNA data to the USGS Nonindigenous Aquatic Species (NAS) database, which currently maps and displays visual identification or physical capture data for non-native aquatic species. We have been working within the invasive species and eDNA communities to establish...

Identifying, extracting, and mobilizing information from current and historical literature is a time-consuming part of organizing and collating synthetic data productions. This project explored the use of algorithm-based methods to identify and extract occurrence information from the GeoDeepDive (GDD) literature database to support upkeep of the Nonindigenous Aquatic Species (NAS) data. The GeoDeepDive API was extended to include query capabilities on terms from the Integrated Taxonomic Information System (ITIS). This functionality helped support identification of literature mentioning/focusing on species that are tracked by the Nonindigenous Aquatic Species Database. These methods were paired with algorithms to...

The Nonindigenous Aquatic Species (NAS) Database and Alert System (https://nas.er.usgs.gov/default.aspx) provides a framework for the rapid dissemination of new invasions as they are incorporated into the NAS Database. The system notifies registered users of new sightings of >1,330 non-native aquatic species as part of national-scale early detection and rapid response systems (EDRR), and in support of several federal programs: National Invasive Species Council, Aquatic Nuisance Species Task Force, and other Department of the Interior agencies. The NAS group has developed a new tool, the Alert Risk Mapper (ARM; https://nas.er.usgs.gov/AlertSystem/default.aspx), to characterize river reaches, lakes, and other waterbodies...

Identifying the leading edge of a biological invasion can be difficult. Many management and research entities have biological samples or surveys that may unknowingly contain data on nonindigenous species. The new Nonindigenous Aquatic Species (NAS) Database automated online tool “SEINeD” (Screen and Evaluate Invasive and Non-native Data) will allow a user to search for these nonindigenous occurrences at a push of a button. This new tool will enable stakeholders to upload a biological dataset of fishes, invertebrates, amphibians, reptiles, or aquatic plants collected anywhere in a U.S. State or Territory and screen that data for non-native aquatic species occurrences. In addition to checking for the nativity of species...
