Assessing Climate Change Vulnerability of Breeding Birds in Arctic ...

vulnerable” for the Yellow-billed Loon isconsidered “low” because the simulationresults are almost evenly distributedbetween the highly vulnerable, moderatelyvulnerable and presumed stable categories.In contrast, the confidence in the result forthe Semipalmated Sandpiper is considered“high” because over 80% of the simulationoutcomes fell in the presumed stablecategory.Figure 3.3. The numerical vulnerability scores andindex categories as assigned by the CCVI tool usingthe initial climate scenario as the exposure inputs(Temp: SNAP 5-model composite/Moisture: CW 5-model average (SNAP models).Index Score Vulnerability Category>10.0 Extremely vulnerable (red)7.0-9.9 Highly vulnerable (orange)4.0-6.9 Moderately vulnerable (yellow)-2.0-3.99 Presumed stable (blue)
