TABLE 1.
Scope, severity, and impact of the threat of white‐nose syndrome (WNS) on 5 hibernating bat species based on NatureServe criteria
| Species | Scope of WNS threat (%) | Percent severity of WNS threat (95% credible interval) | Scope level | Severity level | Impact of WNS threat |
|---|---|---|---|---|---|
| Myotis septentrionalis | 79 | 100 (97, 100) | pervasive | extreme | very high |
| Myotis lucifugus | 36 | 98 (96, 100) | large | extreme | high |
| Perimyotis subflavus | 59 | 93 (90, 100) | large | extreme | high |
| Myotis sodalis | 93 | 28 | pervasive | moderate | medium |
| Eptesicus fuscus | 32 | 35 (13, 54) | restricted | serious | medium |
Percent overlap of species and WNS occurrence ranges weighted by proportion of sites with observed declines.
Estimate of percent mean declines at hibernacula with WNS establishment; 95% credible interval from Eq. 1.
Due to extreme skew in colony sizes and variation in declines of M. sodalis, estimates of severity of WNS threat ranged from 84% (95% credible interval 78–100%) based on Eq. 1 to 28% based on mean site‐level declines derived from Eq 3. Severity and impact is 28% based on our best understanding of the model fit and data (Appendix S2).
