The eDNAtlas database consists of three feature classes. The first component (eDNAtlas_EastWest_AGOL_ResultsOnly) is a database of georeferenced species occurrence locations based on eDNA field sampling results, which are downloadable by species through a dynamic ArcGIS Online (AGOL) mapping tool. The earliest eDNA samples in the database were collected in 2015 but new samples and results are added annually to the database, which houses thousands of species occurrence records. The second and third components (eDNAtlas_East_AGOL_SampleGridAndResults and eDNAtlas_West_AGOL_SampleGridAndResults) are a systematically-spaced 1-kilometer grid of potential sample points in streams and rivers throughout the eastern and western United States, respectively. The points in the sampling grid are arrayed along the medium-resolution National Hydrography Dataset Version 2 (NHDPlusV2) and can be used to develop custom eDNA sampling strategies for many purposes. Each sample point has a unique identity code that enables efficient integration of processed eDNA sample results with the species occurrence database.If downloaded from the ArcGIS Online map, these data may have been filtered or extracted by the user and may not be complete.For more information, see the website - https://www.fs.usda.gov/rm/boise/AWAE/projects/eDNAtlas/the-edna-atlas-results.html |
