It includes animals and plants. This dataset was produced by the US EPA to support research and online mapping activities related to the EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets). This dataset could act as a starting point for further review and evaluation of freshwater biodiversity conservation needs. The overall goal of the EnviroAtlas is to employ and develop the best available science to map indicators of ecosystem services production, demand, and drivers for the nation. completed EnviroAtlas Coordinator U.S. Environmental Protection Agency, Office of Research and Development-Sustainable and Healthy Communities Research Program, EnviroAtlas Geospatial Data Owner (919) 541-3832 109 T.W.

These numbers are based on occurrence data drawn from publicly accessible databases, and reflect compilations of non-native species observations from multiple independent data sources. Data on non-native aquatic species occurrences were drawn from multiple publicly accessible databases. These include the U.S. Geological Survey (USGS) Non-indigenous Aquatic Species database (primarily for animal species) as well as the Early Detection and Distribution Mapping System (EDDMapS) and the USGS Biodiversity Serving Our Nation (BISON) database, which is the US data repository for the Global Biodiversity Information Facility (GBIF). The USGS NAS API's URL is http://nas.er.usgs.gov/api/v1; documentation can be found at https://nas.er.usgs.gov/api/documentation.aspx. EDDMapS data were downloaded from https://www.eddmaps.org/Species/. The BISON database is at https://bison.usgs.gov. BISON data was obtained from http://bison.usgs.gov/solr/occurrences/select/ with the species name and other variables appended to the URL. We restricted the database to only those species that are non-native to the conterminous United States, and excluded species introduced from their primary US native range to other regions of the country. Non-native species richness was determined by simply summing the number of species observed to occur within each subwatershed. To learn more about how the database was assembled, see Davis, A. J. S.; Darling, J. A.; Leung, B., Recreational freshwater fishing drives non-native aquatic species richness patterns at a continental scale. Diversity and Distributions 2017.
