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 FSim burn probability was used to determine the majority (most common) burn probability within a 4km analysis unit in areas with other conifer vegetation communities withing the ecoregion.
Prey base condition data were extracted from the EPA 303d listing and analyzed to determine the prey base quality within Bald eagle potential suitable habitat. The quality of a HUC in relation to distance to agricultural areas was defined as good (3), fair (2), or poor (1). The score indicates the threat level for each attribute. A low score indicates a low threat, a medium score indicates a medium threat, and a high score indicates a high threat to the species. The values for each score were characterized in relation to impaired waterways. The scale ranged from 1(303d listed) to 3 (non-303d listed) and were averaged by HUC or REA 4km Grid, resulting in a score value range from 1 to 3.
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.
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”).
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/.

WGA Landscape Integrity Interconnect Zones for Forest Biome linking Large Intact Blocks.There was no metadata received with the orginial vector layer.
Nest site and perch locations were derived from the NLCD (all forested cover types) were analyzed to determine the distance from Bald eagle potential suitable habitat. The quality of a HUC in relation to distance to nest site and perch locations was defined as good (3), fair (2), or poor (1). The score indicates the threat level for each attribute. A low score indicates a low threat, a medium score indicates a medium threat, and a high score indicates a high threat to the species. The values for each score were characterized in relation to distance from nest site and perch locations by 2km = poor.
Agricultural areas were extracted from state vegetation mapping and their location was compared to location of identified breeding bird density (75%) areas. Breeding bird density areas were mapped by Doherty et al. 2010.16 - 32 % agriculture = moderate> 32 % agriculture = low quality

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.

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.
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.
