Results of sensitivity analysis, indicating importance of climate-related variables in determining suitable habitat for trout under climate change

Condition	Cutthroat	Brook	Rainbow	Brown
Current suitable stream length	159	130	112	80
Projected suitable stream length under 2080s scenario	68	30	73	42
Projected in 2080s if no change in temperature	187 (×2.8)	92 (×3.1)	162 (×2.2)	45 (×1.1)
Projected in 2080s if no change in winter high flows	77 (×1.1)	45 (×1.5)	46 (×.63)	75 (×1.78)
Projected in 2080s if no change in temperature or winter high flows	205 (×3.0)	131 (×4.4)	114 (×1.6)	81 (×1.9)
Projected in 2080s if no change in mean flow	69 (×1.0)	30 (×1.0)	72 (×0.99)	41 (×0.98)

Values indicate projected length of suitable habitat under current conditions (row 1), under projections for the 2080s A1B composite scenario (row 2), and under the 2080s A1B composite scenario with selected climate metrics held constant at current levels (rows 3–6). Units are km × 1,000. Values in parentheses indicate change relative to the 2080s A1B composite scenario (row 2).
