This presentation is a product of the 2014 CDI Project: NASWeb API Web Services Access to the Nonindigenous Aquatic Species Database. It was presented on Mar. 11, 2015 as part of the CDI Monthly Forum.

This map was created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with Hurricane Maria. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along coastal regions. This map will help natural resource managers determine potential new locations for individual species, or to develop a watch list of potential new species within a watershed. These data include a subset of data from the Nonindigenous Aquatic Species Database, that fall within the general area of the 2017...

This map was created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with Hurricane Irma. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along coastal regions. This map will help natural resource managers determine potential new locations for individual species, or to develop a watch list of potential new species within a watershed.

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...

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...

The national Nonindigenous Aquatic Species (NAS) Database Program serves as a repository for geo-referenced occurrence data on introduced aquatic organisms across the nation. The NAS Program, including the database and website (http://nas.er.usgs.gov), is a well-known resource and has been widely referenced in peer reviewed literature, agency reports, state and national management plans, news articles and other locations. Access to NAS occurrence data is currently restricted to three channels: directly through the NAS website (primarily single occurrence records and species distribution maps), distributed databases (e.g, GBIF, BISON), and custom data queries directly through NAS program staff. The goal of this project...

This refined map was created to help assess possible spread of nonindigenous aquatic species distributions due to flooding associated with Hurricane Harvey. Storm surge and flood events can assist expansion and dissemination of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along coastal regions. This map will help natural resource managers determine potential new locations for individual species, or to develop a watch list of possible new species within a watershed. These data include a subset of data from the Nonindigenous Aquatic Species Database, that fall within the general...

This map was created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with Hurricane Nate. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along coastal regions. This map will help natural resource managers determine potential new locations for individual species, or to develop a watch list of potential new species within a watershed.
