For the Green River Basin Landscape Conservation Design (GRB LCD) assessment, we mapped the vulnerability of riparian habitat for terrestrial species and process. Using a vulnerability framework, we defined Sensitivity (S) as the percent riparian vegetation within the valley bottom and Exposure (E) as the amount of human modification within the valley bottom. For each 12-digit hydrologic unit code within the GRB LCD we summarized the riparian sensitivity and exposure to human modification. We also computed Potential Impact (PI), and Adaptive Capacity (AC) metrics at the HUC12 level. PI is the square root transformed product of human modification exposure and riparian sensitivity. AC for riparian exposure to human...

For the Green River Basin Landscape Conservation Design (GRB LCD) assessment, we mapped the vulnerability of occupied Colorado River cutthroat trout (Oncorhynchus clarkii pleuriticus) habitat to climate change for each 12-digit hydrologic unit. Cutthroat trout occupied habitat was mapped from the range-wide status report (Hirsch et. al 2013). Using a vulnerability framework, we defined Sensitivity (S) as the total length of occupied cutthroat trout habitat within HUC12 polygons. The exposure parameter incorporates two climate change metrics, the change in flow timing and change in stream temperature. Exposure is quantified as the square root transformed product of the two climate change metrics. Potential Impact...

The landscape permeability model represents the structural connectivity of sagebrush ecosystem habitat in the Green River Basin (including ~5-10 km boundary outside of the GRB. This model connects patches of habitat, across the landscape using resistances that represent the degree of human modification and slope (energetic costs), using the Multi-Scale Landscape Permeability model (Theobald et al. 2012; Theobald unpublished). We used two metrics: (a) patch importance and (b) betweeness centrality amongst patches. These metrics were summarized for each HUC12. This dataset represents the vulnerability of sagebrush ecosystem permeability to human modification summarized for each HUC12 watershed within the Green River...
