Table 1 Calculated sensitivity weights using the product, absolute mean, or normal mean methods for mountain goat ( Oreamnos americanus ) in Idaho. Weights calculated using the product or absolute mean method use only the magnitude and do not consider the direction of the species sensitivity. The normal mean method incorporates both the magnitude and direction of species sensitivity. Where two numbers are listed the first is applied where the characteristic is projected to be negative, and the second where the characteristic is projected to be positive. This is because some aspect of the species sensitivity has been listed as sensitive to any change, or it is unknown what direction of change the species is sensitive to.

Table 2 Calculated sensitivity weights using the product, absolute mean, or normal mean methods for Columbia spotted frog ( Rana luteiventris ) in Idaho. Weights calculated using the product or absolute mean method use only the magnitude and do not consider the direction of the species sensitivity.

Where two numbers are listed the first is applied where the characteristic is projected to be negative, and the second where the characteristic is projected to be positive. This is because some aspect of the species sensitivity has been listed as sensitive to any change, or it is unknown what direction of change the species is sensitive to.

Supplemental Figures
Fig. 1 Sensitivity rankings for the mountain goat in Idaho. Hashing indicates low confidence, an asterisk indicates high confidence, a lack of markings indicates moderate confidence. These values are informed by the Climate Change Sensitivity Database, expert opinion, and literature review
Fig. 2 Seasonal effect of climate change (sensitivity weighted climate exposure) for mountain goat in Idaho in ( a – c) spring, ( d – f) summer, ( g – i) autumn, and ( j – l) winter using three approaches to calculating sensitivity metrics. Hashing indicates areas outside of the species’
Northwest Regional GAP range.
Fig. 3 Annual effect of climate change (sensitivity weighted climate exposure) for mountain goat in Idaho using a 5 model ensemble mean for the Special Report on Emission Scenarios (SRES)
A2 end-of-century scenario. Hashing indicates areas outside of the species’ Northwest Regional
GAP range.
