      <abstract>This dataset contains two predictive lek (breeding site) persistence raster layers covering the U.S. greater sage-grouse distribution. In the United States, locations where males display and breed with females (i.e., leks) are often monitored annually by state wildlife agencies, providing valuable information on the persistence of birds in the surrounding areas. A U.S. range-wide lek database was recently compiled for greater sage-Grouse (O’Donnell et al. 2021), providing a standardized source of information to build statistical models to evaluate environmental characteristics associated with lek persistence. The compiled lek database classified a subset of leks as being either active (leks currently used for breeding activities) or inactive (leks no longer used for breeding activities) based on count data collected over a 20-year monitoring period. We fit the outcome of a lek being active or inactive as a function of environmental predictors characterizing surrounding conditions in a logistic regression model. Covariates included sagebrush cover, pinyon-juniper cover, topography, precipitation, point and line disturbance densities, and landscape configuration metrics. We included the Bureau of Land Management habitat assessment areas (termed mid-scales) as regional random effects in the form of random intercepts and random slopes (for a subset of covariates). The final model included 13 covariates. We predicted conditional probabilities of lek persistence across the U.S. occupied range using the covariate layers and regional mid-scales, which we make available here as a 30-meter resolution continuous raster dataset. The predictions were conditional because they were specific to each mid-scale factor level (i.e., pixel predictions were influenced by the regional mid-scale polygon they fell within via the associated mid-scale intercept and random slope deviations). We applied sensitivity thresholds (capturing percentage of leks correctly classified as active) to the continuous probability layer to bin persistence probabilities into high, medium, low, and marginal areas of persistence, which we make available here as a 30-m categorical raster dataset.</abstract>
      <purpose>These datasets were created to identify areas within the greater sage-grouse U.S. range where breeding sites (i.e., leks) are predicted to persist based on current environmental conditions. The datasets could be used as a general assessment tool for habitats within various defined areas (e.g., by averaging pixels of the conditional predicted lek persistence probabilities), or to identify areas where active leks are most likely to be located (using the habitat categories defined by model sensitivities).</purpose>

    <native>We conducted all modeling in R v. 4.0.2 (R Core Team 2020) using the package lme4 v. 1.1-28 (Bates et al. 2015). All native spatial raster predictor data were processed in ArcMap v. 10.7 and v. 10.6 (Esri, Redlands, CA), and in the case of landscape metric predictor variables, created using the R package landscapemetrics v. 1.2-18 (Hesselbarth et al. 2019). Covariate extractions at lek locations were done using the R package exactextractr v. 0.4.0 (Baston 2020). The spatial prediction raster was made in R using the packages raster v. 3.3-13 (Hijmans 2020) and rgdal v. 1.5-16 (Bivand et al. 2020) and applying the model formula to a spatial predictor raster stack.</native>

      </srcinfo>
      <procstep>
        <procdesc>Prior to producing lek persistence maps we processed spatial predictor data layers (i.e., covariates) for modeling. The lek persistence model included 13 covariates that were extracted from these processed raster datasets. The covariate raster datasets included a combination of publicly available data (these layers were not modified beyond simple operations such as reprojecting or masking prior to covariate extractions), proprietary data (layers provided to us by partners internally that were not publicly available for distribution), and interim data (intermediate layers we created solely for the purpose of this project). All raster datasets were reprojected to Albers Conical Equal Area in the North American Datum 1983 and resampled to a 30-m resolution unless their native attributes matched these specifications. All raster datasets covered the full extent of the U.S. greater sage-grouse distribution. Below, we describe the covariate raster datasets in their native (starting) format. Unless noted, raster processing was conducted in ArcMap v. 10.7.

Boundary distance (interim layer): We calculated a Euclidean distance raster that measured the distance (in meters) to the U.S. greater sage-grouse distribution boundary for every pixel. The greater sage-grouse distribution boundary was an internally produced USGS product unavailable to the public.

Elevation (publicly available layer): We used a global 30 arc-second (1-km resolution) digital elevation model (GTOPO30) available from USGS to represent elevation in meters (Danielson and Gesch 2011: https://doi.org/10.3133/ofr20111073). 

All sagebrush cover (publicly available layer): We used the National Land Cover Dataset (NLCD) 2016 Shrubland Fractional Components for the Western U.S. (ver. 2.0, October 2019) sagebrush shrubland fractional component layer to represent continuous sagebrush cover as a percentage of each pixel (Homer 2019: https://doi.org/10.5066/P9LTU2QM).

Pinyon-juniper cover (publicly available layer): Conifer cover was represented using a modeled raster dataset representing conifer conditions from 2012-2013 (Falkowski et al. 2017: https://doi.org/10.1016/j.rama.2016.08.002). We modified this layer by reclassifying it into a binary layer, distinguishing conifer cover classes between 4-10% (1 values) from all other classes (0 values). 

Sagebrush habitat (publicly available layer): The BLM provided a binary sagebrush classified habitat layer. The layer was created by reclassifying the 2016 LANDFIRE Existing Vegetation Type (EVT) 2.0.0 dataset categories (7064, 7072, 7079, 7080, 7124, 7125, 7126) as sagebrush habitat (1 values), and all other EVT categories as non-sagebrush habitat (0 values).

Sagebrush habitat and sagebrush-associated habitat (publicly available layer): The BLM provided a binary layer that distinguished sagebrush habitat and sagebrush-associated habitat from all other categories. The layer was created by reclassifying the 2016 LANDFIRE Existing Vegetation Type (EVT) 2.0.0 datasets categories to capture both sagebrush habitat (7064, 7072, 7079, 7080, 7124, 7125, 7126) and sagebrush-associated habitat (7062, 7065, 7081, 7085, 7086, 7107, 7123, 7127, 7141, 7148, 7250) as 1 values, and all other EVT categories as 0 values. This layer did not appear in the lek persistence model as a stand-alone covariate, but was used for landscape metric covariate calculations (described below).

Landscape metrics (interim layer): We created 3 landscape class metric raster layers, including core area index (a core area metric), edge density (an edge metric), and clumpiness index (an aggregation metric), at the class level within circular buffers that represented different landscape scales (ranging from 1- to 6.4-km radii) using the package landscapemetrics in R. We applied the landscape class metrics to a raster layer that was the sum of the sagebrush habitat and sagebrush-associated habitat rasters. Landscape metrics were computationally intensive to calculate and could not be directly calculated for every 30-m pixel within the greater sage-grouse distribution. To overcome this, we produced a sample grid of points where landscape metrics were calculated at every point for each of the 3 metrics, and then we interpolated landscape metric values between points using inverse weighted distance interpolation implemented with the IDW tool in ArcMap to create a continuous raster dataset. A full description of this process is provided in the supplemental materials document (SM1.4) associated with Wann et al. (In review).

Vector ruggedness measure (interim layer): The vector ruggedness measure (VRM) was derived from a 1/3 arc-second (10-m resolution) digital elevation model (USGS 3D Elevation Program: https://apps.nationalmap.gov/downloader/) and applying transformations from the methodology of Sappington et al. (2007). Processing occurred in ArcMap v. 10.6. Pixel values represented a decomposition of slope and aspect into 3-dimensonal vectors summarized within a 1000-m moving window, which provided a measure of terrain ruggedness, independent of slope.

Compound topographic index (interim layer): The compound topographic index (CTI) was derived from a 1/3 arc-second (10-m resolution) digital elevation model (USGS 3D Elevation Program: https://apps.nationalmap.gov/downloader/) and applying transformations from the methodology of Gessler et al. (1995). Processing occurred in ArcMap v. 10.6. CTI represents a steady-state wetness, a function of slope and upstream contributing area per unit width that is orthogonal to the flow direction (i.e., ratio of catchment area and slope). Flatter areas will have large values (typically not informative), while smaller catchments with steep slopes will reflect low values of the index. We used the D8 algorithm to define our catchment area (flow accumulation) and the following equation: ln〖(((flow accumulation+1)* 〖pixel area〗_meters ))/tan(〖slope〗_radians). CTI is often used as a surrogate for soil moisture and vegetative productivity; however, this index does not work well for larger geographic extents where precipitation differs. Therefore, we defined our flow accumulation by weighting it using 1980 – 2010 total precipitation normal. We first calculated the index for a 3x3 cell. We then applied moving window scales to create data reflecting different functional scales with aforementioned statistics.

Point disturbance (proprietary data layer): This dataset represents a 30-meter resolution point density analysis derived from an aggregate of twelve merged feature classes representing various anthropogenic structures. To produce this aggregate point layer a suite of datasets were pre-processed as detailed below and combined in ArcMap 10.6. A Point Density Analysis (ArcMap 10.6.1 environment) was run using the point feature class to calculate a magnitude-per-square kilometer of point features that fall within a 534-meter search radius around each 30-meter cell. The process was limited to an extent covering the range of greater sage-grouse in the western US. A description of the feature classes follows. (1) Power Plants: Acquired September 10th, 2016 via data subscription contract. Copyright McGraw-Hill / S&amp;P Global Platts. The Platts Power Plant geospatial data layer contains point features representing Utility and Non-Utility operated power plants in North America. Data was selected based on attribution using ArcGIS to create a subset including only operational power plants with a locational accuracy of 1 mile or less. (2) Oil, Gas, and Geothermal Wells Currently Active and Active within the past 10 years: A subscription to the IHS Enerdeq Browser (https://ihsmarkit.com/products/oil-gas-tools-enerdeq-browser.html) was used to extract information representing wells active after 9/1/2016 and wells having a last production or last activity date prior to 9/1/2006.  These data were exported into a feature class where duplicate API numbers were removed using the Delete Identical function in ArcMap.  Spatially duplicate features were removed using the Delete Identical function in ArcMap on the Shape field. Additional data were extracted from the BLM’s Automated Fluid Support System (AFMSS) by Joy Fleet, BLM Program Analyst, on 09/30/2016.  Data Contact: AFMSS Program Manager Michael Mulder, mmulder@blm.gov. The extraction included all currently active well and inactive wells which were active within the 10 years prior to 2016.  Data includes Federal, Indian, FEE and State wells that are identified in federal or Indian agreements for the following states: CA, CO, ID, MT, ND, NE, NV, OR, SD, UT, WA &amp; WY.  These data were provided in the form of an excel spreadsheet and those with Latitude and Longitude information were mapped using the “Add X/Y Data” function in ArcMap.  Duplicate API numbers were removed using the Delete Identical function in ArcMap on the API number field. Spatially duplicate features were removed using the Delete Identical function in ArcMap on the Shape field. Duplicate wells between the IHS and AFMSS datasets, as identified by the API number, were removed from the IHS data.  Spatially duplicate locations between the IHS and AFMSS well data were removed from the IHS dataset.

Major road line disturbance (proprietary data layer): This dataset represents a 30-meter resolution density analysis raster derived from linear disturbance features representing highways and major roads. These road data were extracted from licensed ESRI StreetMaps Premium data (2016 - Release #2, Copyright ESRI and its licensors - All rights reserved).  Highways and major roads were extracted from the ESRI StreetMaps Premium data using attribute queries (ROAD_CL IN [2, 3, 6]).  A Line Density Analysis (ArcMap 10.6.1 environment) was run using the subset of the line features meeting the attribute query criteria to calculate a magnitude-per-square kilometer of linear features that fall within a 534-meter search radius around each 30-meter cell. The process was limited to an extent covering the range of greater sage-grouse in the western US. This data layer is not publicly available owing to the data being proprietary in nature.

Mean annual precipitation (publicly available layer): The USGS calculated a mean annual precipitation variable using the formula for the Bio 12 statistic (O’Donnell and Ignizio 2012: https://pubs.usgs.gov/ds/691/), which was the summation of annual monthly precipitation (measured in millimeters). Mean annual precipitation was therefore the average of Bio 12 for years 1981-2010 (20-year normal). This product used publicly available 800-m resolution down-scaled PRISM monthly precipitation data (Climate Source, Inc, 2011: http://www.climatesource.com/) to produce the mean annual precipitation layer.</procdesc>

        <procdesc>The lek persistence model was fit to lek covariates extracted from the covariate layers produced in Step 1. Briefly, we extracted environmental predictor data at lek locations at 5 circular buffer extents: 1-, 3.2-, 6.4-, 15.0-, and 30-km radii. These extracted values became covariates in a generalized mixed effects logistic regression model relating the binary classification of a lek (as being either active [1] or inactive [0]) to the covariates. For each covariate, a single buffer (scale) was selected that led to the most predictive model fit. Prior to model fitting, all extracted covariates values were z-transformed (i.e., covariate values were centered by subtracting the mean and scaled by dividing by the standard deviation).

The lek persistence R model object was used to produce spatial predictions of conditional probabilities of lek persistence across the full extent of the U.S. greater sage-grouse distribution at a 30-m resolution. Predictions were made using the predict function from the raster library in R. The predict function required two arguments: (1) the model object which contained the model formula, and (2) a raster stack with layers corresponding to the predictor variables fit in the model object. Because the covariates fit in the model were summarized at various buffer extents followed by z-transformation, the original raster predictor layers (which represented data on the original untransformed scale) had to be similarly matched. We did this by first calculating moving window rasters that matched the buffer for a given covariate as it appeared in the final model. For example, sagebrush cover was best supported when summarized at a 3.2-km buffer, which was the scale used to represent sagebrush cover in the final model. Therefore, we calculated a moving window raster with a 3.2-km radius from the original sagebrush layer, to match the scale of the covariate as it appeared in the model. We then z-transformed the moving window raster of sagebrush cover using the same mean and standard deviation as was used in the original extracted covariate z-transformation. This process was repeated for all remaining covariates that appeared in the final model. The final model also included a random effect for the Bureau of Land Management (BLM) mid-scale, which were polygons delineating different habitat assessment regions within the U.S. greater sage-grouse distribution. For categorical predictor variables, the raster predict function required a categorical raster. We converted the BLM mid-scale polygon shapefile into a categorical raster, with each pixel value taking on the value of the polygon it fell within (i.e., the polygon mid-scale identifier, which was a number). Therefore, when we predicted across the greater sage-grouse range, our predicted probabilities of lek persistence were conditional on the factor levels of the mid-scale, which was treated as a random effect. 

We masked the predicted conditional probability of lek persistence layer to the U.S. greater sage-grouse distribution polygon, which was buffered by 2-km to ensure all leks used in model fitting fell within the prediction space.</procdesc>

        <procdesc>We binned the predicted conditional probability surface into “habitat quality” categories corresponding to different levels of model sensitivity (true positive classification rate of leks being active at different probability threshold values). For each mid-scale, we calculated probabilities associated with sensitivities at 0–50% (high-quality), 50–75% (medium-quality), 75–95% (low-quality), and 95–100% (marginal). Using this strategy, the high-quality habitat bin included areas with highest estimated probabilities of lek persistence, while the marginal habitat bin included lowest probabilities. Using R and the raster package, we iterated through each BLM mid-scale and conducted binning in the following steps: (1) we clipped and masked the continuous conditional probability surface to the extent of the focal mid-scale; (2) we reclassified probabilities to values of 1, 2, 3, or 4, based on the associated sensitivity thresholds that corresponded to high-quality, medium-quality, low-quality and marginal habitats. We mosaiced the resulting reclassified mid-scale rasters into a single raster, which resulted in the binned habitat raster.</procdesc>
