U.S. National Atlas Urbanized Areas represents urban areas in the United States derived from the urban areas layer of the Digital Chart of the World (DCW).
This dataset was developed by the USGS for use in regional climate simulation analyses. These data were applied in the BLM REA analysis for the NGB ecoregion. For more information pertaining to these data and climate modeling, please refer to http://regclim.coas.oregonstate.edu/.
Lakes idenitifed containing redband trout in the range-wide assessment.
The 2030 Ponderosa pine viablitly was average based on the 7 climate models and clipped to the ecoregion.
Road features were identified using TIGER line data and those features mapped as freeways, secondary roads and local roads were selected. A moving window analysis was applied, which used a window area of 640 acres to determine the miles of road per 640 acres. Output from the analysis was scored where road density values less than 3 miles/640acres were scored as a 3 (“preferred”) and road density values greater than 3 miles/640acres received a score of 1 (“lower quality”).
Agriculture and Urban land uses were extracted from Landfire VCC and urban areas were mosaiced with TIGER roads to determine the percentage of those land uses with the riparian corridor.
The PRISM 1980-2010 July mean temperature was extracted for the mountain whitefish range in the ecoregion. The temperature range of the current climate scenario was used to estimate what is a current suitable range and use to assess suitablity for a future climate scenario temperature range. The mean temperature, mean temperature + 1 Standard Deviation and maximum temperature were extracted from the raster statistics. Mountain whitefish has a mean of 30.2*C, Mean + 1SD of 32.8*C and Max Temp of 35.6*C.
EPA Toxic Release Inventory sites was used to determine the proximity of these sites to analysis units containing Columbia spotted frog modeled suitable habitat. If the analysis unit contained a site it was deemed poor and it had no sites this was classed as good habitat for this key ecological attribute.

Current yellowstone cutthroat trout lake populations as identified during the 2011 yellowstone cutthroat trout assessment meetings.
The FSim burn probability was used to determine the burn probability of the white sturgeon range in the ecoregion. This layer was used to examine wildfire risk to areas within the white sturgeon range.
The Transmission Lines layer is a comprehensive layer consisting of market significant transmission lines in North America. Depicted lines are generally greater than 115 kV and tie major power plants to the electrical grid.
The FSim burn probability was used to determine the burn probability of the other conifer vegetation communities. This layer was used in the intactness management question and the results weren't rolled up to an analysis unit.
This dataset was developed by the USGS for use in regional climate simulation analyses. These data were applied in the BLM REA analysis for the NGB ecoregion. For more information pertaining to these data and climate modeling, please refer to http://regclim.coas.oregonstate.edu/.
SSURGO soils was modified for the ecoregion by supplementing gaps in the SSURGO coverage with STATSGO data. This layer was then converted to a raster to make the layer more manageable with spatial modeling. Recently, NRCS has released a new SSURGO layers that is nationwide (gSSURGO) and it should probably be used in the future.

U.S. National Atlas Cities represents cities and towns in the United States.This dataset was used in the Northern Great Basin Rapid Ecoregional Assessment by BLM. No changes were made to the data but the dataset reduced to only included certain cities/towns within the ecoregion.
The FSim burn probability was used to determine the burn probability of the juniper vegetation communities. This layer was used in the intactness management question and the results weren't rolled up to an analysis unit.
