Bioclimatic envelope for limber pine Global climate model CCCM3 emissions A2 in 2030. Data from Rehfeldt, G.E., Crookston, H.L., SaenzRomero, C, and Campbell, E.M., 2012, North 1 American vegetation model for land use planning in a changing climate. A solution to large 2 classification problems: Ecological Applications, v. 22, no. 1, p. 119 to 141.
Terrestrial Development Index (TDI) for Golden eagle in the Wyoming Basin REA project area. TDI scores are based on the percent of surface disturbance footprint from development within a 2.25 km radius moving window for a 15 m cell size. The TDI quantifies the total area of the surface disturbance footprint for five disturbance variable classes: transportation (roads, railroads), energy and minerals (oil and gas wells, wind turbines, mines), transmission structures (towers, transmission lines), and agriculture (pasture, cropland) and urban land covers. TDI scores range from 0 to 100 percent and were divided into seven classes for visualization purposes. Because the development scores are continuous, alternative...
Potential changes in baseline five needle pine based on overlap with the projected bioclimatic envelope distribution. To account for the differences between the current distribution and modeled bioclimatic envelopes, we used results from CCCM3, in 2030, and classified each modeled biome into three change categories: 1 distributions that potentially could decline because current and projected envelope distributions do not coincide, 2 distributions that are not expected to change because the current and projected envelope distributions overlap, and 3 distributions that have the potential for expansion outside the current envelope distribution. Next, we classified potential for change in the current distribution of...
We developed a general habitat model for pygmy rabbits using MaxEnt software, Phillips and others, 2006. Values of vegetation and abiotic variables at 3,066 mapped pygmy rabbit locations, provided by Wyoming Natural Diversity Database, since 1990 were derived from data from SAGEMAP, Hanser and others, 2011, Homer and others, 2012, USGS, and WorldClim. Variables with the greatest weight included the average temperature of the coldest quarter, sagebrush cover, annual mean temperature, and the percent of sand in the soil. The map of potential pygmy rabbit habitat was based on MaxEnt parameter values that included 95 percent of the locations; omission rate of 5 percent. For additional details see the Wyoming Basin Rapid...
This "Surface Management Agency" data layer portrays tracts of federal land for the United States and classifies these holdings by administrative agency. Multiple federal agencies have contributed to the contents of this layer and it is in a continuous state of update. Source and date of feature updates are tracked to the feature level.

The potential effect of development on patch size was used as an index of fragmentation. Patch size was quantified for relatively undeveloped patches (Terrestrial Development Index scores less than or equal to 1 percent) of sagebrush steppe. Because TDI is calculated for a 2.25 km radius moving window, relatively undeveloped patches are defined at this analysis scale. Patch sizes for relatively undeveloped areas can then be compared to baseline conditions.
We used the length of sauger occupied streams as an index of patch size. Stream segments were based on natural and anthropogenic barriers (dams) that restrict bi-directional movements among sauger populations.

Ranks of landscape level ecological risks for sagebrush obligate birds, summarized by township, in the Wyoming Basin Rapid Ecoregional Assessment project area. Landscape level risk based on Terrestrial Development Index (TDI). Risk classes based on mean TDI score by township. Lowest risk corresponds to TDI less than 1, medium risk corresponds to TDI 1 to 3, Highest risk corresponds TDI greater than 3. See table 26.3 and appendix in the Wyoming Basin REA report at http://pubs.er.usgs.gov/publication/ofr20151155 for additional details.
Current West Nile Virus risk (0 to 100) clipped to Sage Grouse baseline distribution, with highest risk being 100 across WYB study area. Data was attained from Ryan Harrigan (iluvsa@ucla.edu) at the Center for Tropical Research, Institute of the Environment, University of California, Los Angeles. work is being currently submitted to Global Change Biology.

Average January temperature for 2046-2060 projected by 36-member ensemble (16 GCMs with multiple runs of some models, all the runs available for BCSD) driven by the A2 emissions scenario at 1/8 degree latitude-longitude (approximately 12km by 12 km) over the Wyoming Basin and surrounding areas. BCSD data downloaded the "Downscaled CMIP3 and CMIP5 Climate and Hydrology Projections," archived at http://gdo-dcp.ucllnl.org/downscaled_cmip_projections/.
Ranks of landscape level ecological values for the montane, subalpine, and alpine community, summarized by township, in the Wyoming Basin REA project area. Landscape level value based on area ofthis community per township. See table 14.3 and the Appendix in the Wyoming Basin REA report for overview of methods.
We assessed development levels in spadefoot assemblage based on the regional Terrestrial Development Index (TDI) map, and then used the resulting output to calculate patch size and structural connectivity metrics. We mapped the structural connectivity of relatively undeveloped areas (TDI less than or equal to 1 percent) for regional connectivity (5.67) based on connectivity analysis. See Chapter 2 Assessment Framework and Appendix of the Wyoming Basin REA Open File Report at http://pubs.er.usgs.gov/publication/ofr20151155 for additional details.
Dams in the Wyoming Basin were selected from dams in the National Hydrography Point Events dataset which are located within 10 m of stream segments containing cutthroat trout.
