A 10 km moving window was used on the Sagebrush conservation element to determine the relative density of Sagebrush within the moving window.
A 10 km moving window was used on the aspen conservation element to determine the relative density of aspen within the moving window.
Riparian vegetation communities were extracted from state ReGAP and Landfire Exisitng Vegetation (California only). The individual rasters were mosaiced to create a single raster than represent Riparian vegetation with the NGB ecoregion.
Development change agents were mosaiced together and the euclidean distance was calculated. Aspen communiities were used to extract the distances. The resulting layer was used in the intactness calculation.
The 2030 aspen viablitly was average based on the 7 climate models and clipped to the ecoregion.
Aspen cummulative score was based on ranking burn probability, distance to disease and distance to development into three categories (1 lowest quality - 3 highest quality). The layers were added together to yield scores ranging from 3 (lowest quality in all three layers) - 9 (highest quality in all three layers).
Development change agents were mosaiced together and the euclidean distance was calculated. Aspen communiities were used to extract the distances then zonal statistics calculated the average within the 4km analysis unit.
The current viablitly was extracted and clipped to the ecoregion.
Aspen was analyzed against Disease Change Agents by computing the euclidean distance from sudden aspen decline stands and then calculating the average value within the 4km analysis unit.
Mixed Conifer Aspen vegetation communities were extracted from state ReGAP and Landfire Exisitng Vegetation (California only). The individual rasters were mosaiced to create a single raster than represent aspen with the NGB ecoregion.
The 2060 Englemann spruce viablitly was average based on the 7 climate models and clipped to the ecoregion.
Aspen vegetation communities were extracted from state ReGAP and Landfire Exisitng Vegetation (California only). The individual rasters were mosaiced to create a single raster than represent aspen with the NGB ecoregion.
The aspen 2060 viablitly was averaged based on 7 climate models and clipped to the ecoregion.
Aspen was analyzed against Disease Change Agents by computing the euclidean distance from sudden aspen decline stands. The resulting dataset was used in the intactness calculation.
The Star Valley Front project was brought up by the Wyoming Game and Fish Department in the early 80's to help improve big game winter ranges. The project area contains mountain shrubland, big sagebrush, and aspen communities that are in less-than-suitable condition. The commumnities continue to decline due in large part to an over-representation of late-seral conditions and an insufficient frequency and extent of fire. Declining habitat conditions in the Star Valley Front project area are having negative effects on mule deer, elk, and moose due to declining forage conditions. Other wildlife species, including several migratory bird species, are being adversely impacted by the loss and decline in quality of mountain...

The 2030 Western juniper viablitly was average based on the 7 climate models and clipped to the ecoregion.
