This data set includes the relative production scenarios for eight (8) grass species based on linear models from Epstein, et al. (1998). We selected two indicator species for each community: shortgrass prairie: blue grama (Bouteloua gracilis; BOGR) and buffalo grass (Bouteloua dactyloides; BODA); mixedgrass prairie: sideoats grama (Bouteloua curtipendula; BOCU) and little bluestem (Schizachyrium scoparium; SCSC); tallgrass prairie: big bluestem (Andropogon gerardii; ANGE) and Indiangrass (Sorghastrum nutans; SONU); and semiarid grasslands: black grama (Bouteloua eriopoda; BOER) and tobosagrass (Pleuraphis mutica; PLMU). Soil texture (percent by weight) came from the Earth Systems Science Center (2008) which provided...
This data set includes the relative production scenarios for bufflaograss [0.72(Temp) - 0.12(Precip) - 0.04(Sand) + 3.08]; this is the model from Epstein, et al. (1998). Soil texture (percent by weight) came from the Earth Systems Science Center (2008) which provided processed soils data from NRCS (gSSURGO), mean annual temperature (Celsius) and/or mean annual precipitation (millimeters) came from contemporary (1981 - 2010) estimates (Maurer et al. 2002) or a GCM. Global Climate Models (GCM) providing scenarios included: warmer-wetter scenario (CESM1-BGC, RCP4.5, Neale et al., 2010), warmer drier scenario (GISS-E2-R, RCP4.5, Schmidt, 2014), hotter-wetter scenario (Miroc-ESM, RCP8.5, Watanabe et al., 2011), and hotter-drier...

A raster dataset of the appropriate management levels of horses in BLM Herd Management Areas (HMAs) and USFS Wild Horse and Burro Territories (WHBT) within Reslience and Resistance classes within the GRSG management zones. This dataset was made by adding the Resilience and Resistance raster to a raster of horse AML levels.

A raster dataset representing conifer cover within the Western United States. This dataset was made reclassifying the LANDFIRE 1.3 EVT layer into "Conifer-dominated Ecological Systems with Little to No Sagebrush", and "Conifer-dominated Ecological Systems Likely to Expand into Sagebrush".

A raster dataset of the percent of tilled agriculture within a 5km radius moving window. This dataset was made by reclassifying the 2014 National Agricultural Statistics Service Cropland Datalayer into to include values of only tilled agriculture, then conductding a moving window analysis on the resulting raster to provide a dataset depicting amount of tilled agriculture within a 5km radius of each 30m pixel. This data was published July 2016.

A raster dataset of the percent of precipitation that falls during summer (July-September). This dataset was made by dividing the 30-year Normal summer (July - September) precipitation value by the 30-year Normal Annual precipitation value. Data is provided at a 900m resolution. This data was published July 2016.

A raster dataset representing the resilience and resistance classes combined with greater sage-grouse breeding habitat probabilities. It was created to represent greater sage-grouse breeding habitat probabilities within each resilience and resistance class. It was created to be incorporated into a larger landscape scale geospatial data modeling effort, the Conservation and Restoration Strategy. The R&R and the GRSG Breeding Habitat Probability raster were incorporated; the resulting raster contained 12 values: 26 - Unsuitable Probability and High R&R 27 - Unsuitable Probability and Moderate R&R 28 - Unsuitable Probability and Low R&R 51 - Low Probability and High R&R 52 - Low Probability and Moderate R&R 53...
This data set includes the relative production scenarios for sideoats grama [1.13(Temp) + 0.41(Precip) - 0.004(Precip)^2- 0.07(Sand) - 12.3]; this is the model from Epstein, et al. (1998). Soil texture (percent by weight) came from the Earth Systems Science Center (2008) which provided processed soils data from NRCS (gSSURGO), mean annual temperature (Celsius) and/or mean annual precipitation (millimeters) came from contemporary (1981 - 2010) estimates (Maurer et al. 2002) or a GCM.

A raster dataset of the appropriate management levels of horses in BLM Herd Management Areas (HMAs) and USFS Wild Horse and Burro Territories (WHBT) within greater sage-grouse (GRSG) habitat probability classes within the GRSG management zones. This dataset was made by adding the GRSG Breeding Habitat Probability Raster to a raster of horse AML levels.

A raster dataset representing sagebrush cover within the Western United States. This dataset was made reclassifying the LANDFIRE 1.3 EVT layer into "Sagebrush-dominated Ecological Systems", and "Grass-dominated Ecological Systems with Sagebrush Components". This data was published July 2016.
thumbnail
A polygon feature class representing the spatial extent and boundaries for BLM Wild Horse and Burro Herd Management Areas (HMAs) and Herd Areas (HAs), along with USFS Wild Horse and Burro Territories (WHBTs). HMAs and WHBTs are color coded to represent whether they are within Appropriate Management Level (AML), Greater than 100% and less than 200% of AML, and greater than 200% of AML. HAs do not have associated AML values, and are colored grey.

A raster dataset of the percent of developed land within a 5km radius moving window. This dataset was made by reclassifying the 2011 National Landcover Dataset Percent Impervioussness Layer into to include values of only developed land, then conducting a moving window analysis on the resulting raster to provide a dataset depicting percent of developed land within a 5km radius of each grid cell. This data was published July 2016.

A raster dataset representing the probability of the surrounding landscape (6.4km radius) supporting a greater sage-grouse lek.This dataset was made by mosaicking the probability of GRSG habitat layers (citation) and classifying them into unsuitable (0.01-0.25), low (0.25-0.50), moderate (0.50-0.65), and high (0.65-1.0) probabilities of the landscape supporting a lek. The publication date of this data is July 2016.
