Abstract:
The eDNA samples in the eDNAtlas database describe species occurrence locations and were collected by the U.S. Forest Service and numerous agencies that have partnered with the National Genomics Center for Wildlife and Fish Conservation (NGC) throughout the United States. This project began in 2015, but updates will include legacy data that were collected using the same protocol. The eDNAtlas database consists of five feature classes.

The first component (eDNAtlas_East_AGOL_SampleGridAndResults) is a systematically-spaced 1-kilometer grid of potential sample points in streams and rivers throughout the eastern United States. 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.

The second component (eDNAtlas_NHDPlusV2_AGOL_ResultsOnly) is a database of georeferenced species occurrence locations based on eDNA field sampling results, which are downloadable by species through dynamic ArcGIS Online (AGOL) mapping tools. The points coincide with the sampling grid and are along the medium-resolution National Hydrography Dataset Version 2 (NHDPlusV2). The earliest eDNA results 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. This feature class includes results from both the western United States and the eastern portion of the country.

The third component (eDNAtlas_NHDPlusHR_AGOL_ResultsOnly) is a point feature class of all eDNAtlas sample locations that are NOT associated with the eDNAtlas NHDPlusV2 1 km sample grid. These features represent sample locations in smalls streams, lakes, wetlands, springs, and other features that are not represented in the NHDPlusV2 digital data. Many of the sample locations have corresponding features in the NHDPlus High Resolution (NHDPlusHR) dataset. When possible, these sample points are attributed with selected NHDPlusHR attributes. Where no NHDPlusHR feature was present but a valid water sample was collected, field points are represented in this feature class, however no NHDPlus attributes are assigned to the attribute table.

The fourth component (eDNAtlas_West_AGOL_SampleGridAndResults) is a systematically-spaced 1-kilometer grid of potential sample points in streams and rivers throughout the western United States. 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.


The fifth component (eDNAtlas_Plains_AGOL_SampleGridAndResults) is a systematically-spaced 1-kilometer grid of potential sample points in streams and rivers throughout the middle “plains” region of the United States. Together with the eDNAtlas_East_AGOL_SampleGridAndResults and the eDNAtlas_West_AGOL_SampleGridAndResults, sample grid and results points are available for the continental United States. 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.

In the feature class attribute tables, the unique ID for each grid sample point is eDNA_ID. The unique ID for each National Genomics Center for Wildlife and Fish Conservation (NGC) lab result is ID_Tag. There can be more than one ID_Tag per eDNA_ID grid sample point.

Purpose:
These data were collected for a variety of project-specific purposes that included: species status assessments, trend monitoring at one or many sites, development of predictive species distribution models, detection and tracking of nonnative species invasions, and assessments of habitat restoration efforts.
Supplemental_Information:
Original metadata date was 08/07/2018.

On 02/28/2019 the data were updated to include 1) the eDNAtlas_East_SampleGridOnly feature class and 2) additional lab results for the western U.S. in eDNAtlas_West_AGOL_ResultsOnly and the eDNAtlas_West_SampleGridAndResults feature classes. This update also included 3) changing the field coordinate field names in the results classes to indicate ‘field’ collection locations instead of the previous ‘UTM’ coordinate notations and 4) includes ten more species to the results table. Additional minor metadata updates were included on 03/27/2019.

On 09/18/2019 the data were updated to include the 1) eDNAtlas_East_AGOL_SampleGridAndResults feature class, which replaced the previous eDNAtlas_East_SampleGridOnly feature class and included results. 2) Additional lab results for the western U.S. in eDNAtlas_EastWest_AGOL_ResultsOnly (renamed from eDNAtlas_West_AGOL_ResultsOnly) and the eDNAtlas_West_SampleGridAndResults feature classes. New lab results were also added for the eastern U.S. in the eDNAtlas_EastWest_AGOL_ResultsOnly feature class, and the extent changed accordingly. 3) This update also included additional species results not in previous versions. 4) Two new fields were created. A “sample_visit” field was added and an ID_Tag field to specify for the lab which Unique ID was assigned to the sample for the PCR run. Location field names were edited to clarify grid locations from field locations. Additional minor metadata updates were included on 11/08/2019. On 12/09/2019 metadata were updated to include information regarding data prior to 2015 that are available.

On 07/31/2020 additional lab results were added including 12 new, additional species across the United States. The metadata were updated to reflect these changes. On 10/23/2020 a few data corrections were made, see Process Steps for details. On 05/04/2021 a few species names were corrected.

On 06/30/2021 additional lab results were added including 17 additional species. A new eDNAtlas_NHDPlusHR_AGOL_ResultsOnly feature class was added, showing lab results of sample points collected outside the eDNAtlas_NHDPlusV2_AGOL_ResultsOnly sample grid. eDNAtlas_NHDPlusV2_AGOL_ResultsOnly was called eDNAtlas_EastWest_AGOL_ResultsOnly in previous versions and was renamed during this update to differentiate between the Results on the systematic grid and the “high res” results that were collected outside that grid. Other modifications include more clear attribute definitions for field and grid xy coordinates. The Sample_Visit field was deleted since the ID_Tag can be used to differentiate between samples at the same location and date.

On 07/28/2022 the metadata was updated to correct old URLs.

On 08/05/2022 additional lab results were added including 13 additional species. The InResults field was included to help differentiate between samples submitted that have lab results and those that do not have results available.

On 05/17/2024 additional lab results were added including 57 additional species. A new feature class was added (eDNAtlas_Plains_AGOL_SampleGridAndResults) that includes sample point in streams and rivers throughout the middle “plains” region of the United States. We have also updated the domains for each 4-character species codes from 1, 2, 3, and 4 to Y, N, IP, and NULL.

Additional minor metadata updates and corrections were made on 07/16/2026.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The laboratory controls are checked for proper amplification (negative = no wells of amplification, positive = 3 wells of amplification).

Samples are again checked for inhibition (> 1 cycle threshold [CT] delay in the internal positive control compared to the internal positive control [IPC] of the negative control). Further, the number of positive wells and the corresponding CT well values are checked for accuracy. If a sample showed positive amplification, the shape of the amplification curve is checked to assure a true detection was present. Species are indicated as present in the shapefile if Positive Wells is > 0.

The lab results species field is populated as follows: Positive Wells = 0; absent = 2 Positive Wells > 0; present = 3

Otherwise fields were populated with: Value = 1 (not sampled) Value = 4 (sampled, being processed). Additional details about quality assurance and quality control checks can be found in the Process Steps below.
Logical_Consistency_Report:
See the Process Steps below.
Completeness_Report:
The only data missing are 1) the site locations that have samples, but haven’t been run yet OR samples that are being re-run due to ambiguous results and 2) samples that contributors requested not be shared.

Protocol used: NGCWFC protocol (Carim et al. 2016)

Quality Checks: Field data collection follows the protocol. Standard laboratory protocols are followed. Data are reviewed for consistency by inspection.

Data Processing & Scientific Workflows: Field data are accompanied by a spreadsheet. Spreadsheet data are examined for consistency and completeness. Laboratory data are directly uploaded to spreadsheets and matched with field data. Data are again reviewed for consistency of results. Suspect results are re-analyzed.

Backup & Storage: eDNA samples are stored in -20 degrees Celsius freezers at the NGC in Missoula. Electronic data are stored on multiple computers at the NGC in Missoula and a USDA Forest Service NAS server in Boise.

Process_Description:
Species occurrence locations in the first element of the eDNAtlas database were determined from water samples collected using the Carim et al. (2016) protocol, which were processed at the NGC lab in Missoula, Montana. In the second element of the eDNAtlas database, stream point locations in the feature dataset comprise a systematically-spaced sampling grid with unique IDs throughout the western United States. These points represent locations for collecting eDNA samples for the eDNAtlas database.


eDNAtlas Sample Point Generation Process

1) NHDPlus Version 2 flowlines were acquired for the western U.S.


2) Flowlines were edited to remove braids and diversions. Flowlines that did not participate in the value added attribute set where also removed.


3) Sample points were generated at a 1 kilometer (km) interval throughout the network with these exceptions.

a) Upstream from each stream junction, the first sample point was placed at 100 meters (m) upstream from the confluence. Subsequent points were established at the 1 km interval.

b) Where stream segments were less than 2 km long, the sample point was placed at the segment midpoint.


4) NHDPlusV2 and Ancillary GIS data were used in the process to assign the following attributes to each sample point.


A unique ID is assigned to each sample point with the form AAAAAAAA-BBB-CC, where A is the 8-digit Watershed Boundary Dataset (WBD, https://nhd.usgs.gov/wbd.html) hydrologic unit code (HUC, https://water.usgs.gov/GIS/huc.html), B is a unique number assigned to each stream reach in the HUC, and C is a unique point on the stream reach. Stream reach attributes are associated with each point to assist users in querying and selecting appropriate sample locations for target species or to develop sampling designs. These attributes include map coordinates for locating points, land ownership, summer flow rate, reach slope, and elevation.

Process_Description:
New lab results incorporated in the database. This included 10 new, additional species. Some new samples had field notes and sample coordinates in a projection other than UTM, prompting the field name changes, for example, from “UTM_X_Easting” to “Field_X_Coord” to better reflect the data. This update also includes the stream sample grid feature class for the eastern portion of the United States.
Process_Date: 2019
Process_Step:
Process_Description:
New lab results incorporated in the database. This included 8 new, additional species, as well as results for points in the eastern United States. Two new fields were created. A “sample_visit” field was added and an ID_Tag field to specify for the lab which Unique ID was assigned to the sample for the PCR run. Location field names were edited to clarify grid locations from field locations.

2019 UPDATES:

Points taken prior to 2015 were sampled using effectively identical protocols and are added to the eDNAtlas Database from previous databases as time allows.

Process_Description:
2020 UPDATES:

On 07/31/2020 new lab results incorporated in the database. This included 12 new, additional species across the United States.

On 10/23/2020 additional data edits were made. The original results of 13 samples were erroneously overwritten with the results of other samples after they had already been QAQC’d. The ID_Tag for those previously incorrect bull trout results are as follows: MT_082118_ANT_16, MT_082118_RAM_1, MT_082118_WOOD_18, MT_082218_RAM_3, MT_082218_RAM_4, MT_082218_RAM_5, MT_082218_RAM_6, MT_082218_RAMT_7, MT_082218_REN_11, MT_082218_REN_12, MT_082218_REN_13, MT_082218_REN_14, MT_082218_REN_15. This update changed the BULL attributes for those points from a “3” back to the original results from the qPCR plate of “2”, showing that lab had not detected bull trout in that sample.

Process_Description:
2021 UPDATES:

On 06/30/2021 additional lab results were added including 17 additional species. A new eDNAtlas_NHDPlusHR_AGOL_ResultsOnly feature class was added, showing lab results of sample points collected outside the eDNAtlas_NHDPlusV2_AGOL_ResultsOnly sample grid. eDNAtlas_NHDPlusV2_AGOL_ResultsOnly was called eDNAtlas_EastWest_AGOL_ResultsOnly in previous versions and was renamed during this update to differentiate between the results on the systematic grid and the results that were collected outside that grid. Other modifications include more clear attribute definitions for field and grid xy coordinates. The Sample_Visit field was deleted since the ID_Tag can be used to differentiate between samples at the same location and date.

2022 UPDATES:

On 7/28/2022 the metadata was updated to correct old URLs.

On 08/05/2022 additional lab results were added including 13 additional species. The InResults field was included to help differentiate between samples submitted that have lab results and those that do not have results available.
Process_Date: 2022

Process_Description:
2024 UPDATES:

On 05/17/2024 additional lab results were added including 57 additional species. A new feature class was added (eDNAtlas_Plains_AGOL_SampleGridAndResults) that includes sample point in streams and rivers throughout the middle “plains” region of the United States.

We have also updated the domains for each 4-character species codes.
It was originally: 1 = not sampled; 2 = sampled, absent; 3 = sampled, present; and 4 = sampled, being processed.
It has been updated to: Y = yes positive wells, species is present; N = no positive wells, species not present; IP = in progress, sample is being processed; and NULL = not sampled, or sampled, analysis not planned.

Please be aware that workflows have been modified and samples that have been taken are only included in the geodatabase if the contributor has given explicit permission to include them. (Which means that a few points in previous versions listed as 'sampled', will now be listed as 'not sampled'.)

DATA FILES

Below is a description of what is included in the Aquatic eDNAtlas ArcGIS GeoDatabase. Each of these entities includes a metadata document with more details.

The data available for download from the Complete GeoDatabase contain various species eDNA lab results from field samples contributed to National Genomics Center for Wildlife and Fish Conservation, as well as information about the date and agency that collected the genetic material. This attribute table also contains other useful information including slope, elevation, and other additional about the sample site location.


Point Feature Classes

eDNAtlas_East_AGOL_SampleGridAndResults: Sampling grid locations with stream point locations comprised of systematically-spaced points with unique IDs along eastern U.S. streams. Used to help users prepare for field work and where eDNA samples have already been taken and where they are still needed. Also used to determine if specific species are being processed or have lab results.

eDNAtlas_NHDPlusV2_AGOL_ResultsOnly: The sampling grid stream points have attributes specifically for the ArcGIS Online maps and contain lab results for species occurrence as well as other point-specific information.

eDNAtlas_NHDPlusHR_AGOL_ResultsOnly: A point feature class of all eDNAtlas sample locations that are NOT associated with the eDNAtlas NHDPlusV2 1 km sample grid. These features represent sample locations in smalls streams, lakes, wetlands, springs, and other features that are not represented in the NHDPlusV2 digital data. Many of the sample locations have corresponding features in the NHDPlus High Resolution (NHDPlusHR) dataset. When possible, these sample points are attributed with selected NHDPlusHR attributes. Where no NHDPlusHR feature was present but a valid water sample was collected, field points are represented in this feature class, however no NHDPlus attributes are assigned to the attribute table.

eDNAtlas_West_AGOL_SampleGridAndResults: Sampling grid locations with stream point locations comprised of systematically-spaced points with unique IDs along western U.S. streams. Used to help users prepare for field work and where eDNA samples have already been taken and where they are still needed. Also used to determine if specific species are being processed or have lab results.

eDNAtlas_Plains_AGOL_SampleGridAndResults: Systematically-spaced 1-kilometer grid of potential sample points in streams and rivers throughout the middle “plains” region of the United States. Together with the eDNAtlas_East_AGOL_SampleGridAndResults and the eDNAtlas_West_AGOL_SampleGridAndResults, sample grid and results points are available for the continental United States. 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.
