Abstract:
These data include 2014 - 2020 eDNA field sample points indicating lab results for presence or absence of bull trout. Sample sites are spaced at a 1 kilometer interval throughout the historical range of bull trout. eDNA stream samples are collected and species presence/absence is determined by analyses at the National Genomics Center. Results are recorded in the feature attribute table of the eDNA sample site shapefile. One point feature in the shapefile was generated for each 1 kilometer sample point in the bull trout eDNA feature class. Where multiple samples were collected at a single eDNA sample site, replicate point features will occur at a single location in the shapefile.

The bull trout is an ESA-listed species with a historical range that encompasses many waters across the Northwest. Though once abundant, bull trout have declined in many locations and are at risk from a changing climate, nonnative species, and habitat degradation. Informed conservation planning relies on sound and precise information about the distribution of bull trout in thousands of streams, but gathering this information is a daunting and expensive task. To overcome this problem, we coupled 1) predictions from the range-wide, spatially precise Climate Shield model on the location of natal habitats of bull trout with 2) a sampling template for every 8-digit hydrologic unit in the historical range of bull trout, based on the probability of detecting bull trout presence using environmental DNA (eDNA) sampling (McKelvey et al. 2016). The template consists of a master set of geospatially referenced sampling locations at 1-kilometer intervals within each cold-water habitat. We also identified sampling locations at this same interval based on the U.S. Fish and Wildlife Service's (USFWS) designation of critical spawning and rearing habitat. Based on field tests of eDNA detection probabilities conducted by the National Genomics Center for Wildlife and Fish Conservation, this sampling approach will reliably determine the presence of populations of bull trout, as well as provide insights on non-spawning habitats used by adult and subadult fish. The completed bull trout eDNA survey results are available through an interactive ArcGIS Online Map. The map provides the ability to zoom in and look at an area of interest, as well as to create queries or select an area to download points as a shapefile.
Purpose:
Results from collected eDNA field sample locations indicating presence or absence of bull trout. The points represent lab results starting in 2015 and updated at least once a year based on participation. Points taken prior to 2015 were sampled using effectively identical protocols and are added to the eDNAtlas Database from previous databases as time allows.

Analytical_Tool_Description:
Climate Shield: Populations of many cold-water species are likely to decline this century with global warming, but declines will vary spatially and some populations will persist even under extreme climate change scenarios. Especially cold habitats could provide important refugia from both future environmental change and invasions by non-native species that prefer warmer waters. The Climate Shield website hosts geospatial data and related information that describes specific locations of cold-water refuge streams for native Cutthroat Trout and Bull Trout across the American West. Forecasts about the locations of refugia could enable the protection of key watersheds, be used to rally support among multiple stakeholders, and provide a foundation for planning climate-smart conservation networks that improve the odds of preserving native trout populations through the 21st century.

Climate Shield was inspired by the landscapes of the Rocky Mountains and people everywhere that are working to preserve native trout. The Northern Rockies Adaptation Partnership (http://adaptationpartners.org/nrap/) provided a valuable forum that accelerated this work. The Great Northern and North Pacific Landscape Conservation Cooperatives generously funded the NorWeST project (https://www.fs.fed.us/rm/boise/AWAE/projects/NorWeST.html), which serves as the foundation for Climate Shield.

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 CT delay in the internal positive control compared to the 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.

Bull trout are indicated as present in the shapefile if Positive Wells is > 0. The BT_Present field is populated as follows:
Positive Wells = 0; absent = 2
Positive Wells > 0; present = 3

Other BT_Present fields were populated with:
Value = 1 (not sampled)
Value = 4 (sampled, being processed)

STEP 1: BT eDNA Metadata for Generating Sample Points

Sample points were generated using NHDPlus Version 2 (NHDPlusV2) flowlines (McKay et al. 2012) as the spatial foundation. The points were only located on a portion of the NHDPlusV2 flowlines that corresponded with Climate Shield (Isaak et al. 2015) cold water habitat patches or U.S. Fish and Wildlife Service designated critical bull trout habitat (U.S. Fish and Wildlife Service 2014). Sample points were generally spaced at a 1 kilometer (km) intervals along the stream network. Specifically, an initial sample point was placed 100 meters (m) upstream from each confluence or outlet. Subsequent sample points along the reach were spaced at 1 km intervals up to the next confluence or headwater initiation point. Reaches between confluences that were shorter than 200 meters had a sample point placed only at the midpoint of the reach. Slope was computed for stream reaches. USGS 30 m DEM data were used to compute channel gradient from the focal point, upstream to the next sample point, confluence, or headwater initiation point.

STEP 3: Samples are tested at the National Genomics Center for Wildlife and Fish Conservation (https://www.fs.fed.us/research/genomics-center/edna/).

Quality Assurance/Quality Control Procedures (QAQC) - Thomas Franklin (thomas.franklin@usda.gov):

The final QAQC process involves checking all of the data from each sample’s qPCR analyses. The raw data (in the form of an amplification plot viewed in StepOnePlus or QuantStudio Design & Analysis Software) are compared to the data in the Mastersheet. The laboratory controls are check for proper amplification (negative = no wells of amplification, positive = 3 wells of amplification). Samples are again checked for inhibition (> 1 CT delay in the internal positive control compared to the 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. Any notes about the sample are added to the “PCR Notes” or “Comments” column. After a sample has been QAQC’d, the QAQC completion date and initials of the researcher are placed in the “Comments” column. Lastly, a “1” or “0” is placed in the final data column. A “1” represents a sample in which the data in that row are ready to be published. A “0” represents a sample in which the data in that row are not ready to be published (sample is inhibited, needs to be reanalyzed, etc.).


Sharon Payne (this information was used to create the BT_Present column in the shapefile):

PCR Date = Date PCR was run

Inhibited (0,1,2,3) =
0 = PCR Ran, not inhibited;
1 = PCR Ran, sample inhibited. Blank in Positive wells - CT Well 3 if no results can be gathered due to inhibition. If results can still be gathered even though sample is inhibited, the Positive wells - CT Well 3 columns will have CT numbers in them.;
2 = Treated for inhibition, PCR Ran, still inhibited. Nothing entered in Positive wells through CT Well 3 if no results can be gathered due to sustained inhibition. If results can still be gathered even though sample is inhibited, the Positive wells through CT Well 3 columns will have CT numbers in them;
3 = Treated for inhibition, PCR ran, sample no longer inhibited.

Positive Wells = Number of positive wells (1-9)

CT Well 1 = CT result. Real number <= 45. 45 indicates negative result for species
CT Well 2 = CT result. Real number <= 45. 45 indicates negative result for species
CT Well 3 = CT result. Real number <= 45. 45 indicates negative result for species
CT Well 4 = CT result. Real number <= 45. 45 indicates negative result for species
CT Well 5 = CT result. Real number <= 45. 45 indicates negative result for species
CT Well 6 = CT result. Real number <= 45. 45 indicates negative result for species
CT Well 7 = CT result. Real number <= 45. 45 indicates negative result for species
CT Well 8 = CT result. Real number <= 45. 45 indicates negative result for species
CT Well 9 = CT result. Real number <= 45. 45 indicates negative result for species

eDNA Quant = Mean eDNA quantity if a standard curve was used.

PCR Notes = Notes for run. If PCR ran and sample was inhibited but positive results could be verified, enter # of positive wells and CT results but note that sample was inhibited and CT values could be delayed/skewed. Note if diluted to treat for inhibition.

Comments = Any comments about the sample or run

Final Data =
0 = Data in this row are not to be published. This sample has been (or will be) reanalyzed and the final data can be found in a new row. For example, if an ID Tag was analyzed multiple times for the same species (example - reran sample to confirm DNA present not from contamination) and therefore has multiple rows of data (new row for each PCR data) but we only want to report one outcome for the ID Tag/Species Code combination.
1 = Data have been QAQC'd and are ready to be published for this ID Tag/Species Code combination. This represents the final data for that ID Tag/Species Code combination.
2 = Sample has been collected for this site. Results are being processed.

***Please note the 0/1 has nothing to do with the presence/absence of a species at that given site***

Bull trout are indicated as present in the shapefile if Positive Wells is > 0. The BT_Present field is populated as follows:
Positive Wells = 0; absent = 2
Positive Wells > 0; present = 3

Other BT_Present fields were populated with:
Value = 1 (not sampled)
