Threats

Threats

White-nose syndrome (WNS) is a fungal disease associated with mass die-offs of hibernating bats. WNS has killed more than 5.5 million bats in the northeastern United States and eastern Canada. It continues to spread rapidly but has not yet reached western or northern Canada (www.whitenosesyndrome.org).

General Status Rank
Rank: 
Undetermined
Status Rank Description: 
White-nose syndrome (WNS) is not documented in this species yet but that may be because they are a western species and WNS has not arrived in the west yet. As a hibernating Myotis, this species is expected to be vulnerable to WNS if and when the disease spreads to the west. A survey of western bat biologists in 2013 ranked the level of WNS risk for this species as between ‘uncertain’ and ‘definite’ (Western Bat Working Group survey, 2013).
S Rank: 
SU
Decision Process Description: 
New rank after publication of NWT Species 2006-2010 report. Reviewed in 2010, modified to may be at risk (J. Wilson). Reviewed in 2015, no change. Reviewed in 2020, modified from may be at risk to undetermined after formal assessment of Data Deficient (SARC 2017).
