Little Brown Bat Survey

Joint Base Elmendorf-Richardson
Ongoing from August 2016 

 Little brown bats (myotis lucifugus) nationwide are suffering massive die-offs associated with a fungal disease known as White Nose Disease Syndrome. The State of Alaska has identified little brown bats as a species of special concern and federal protections under the Endangered Species Act could follow.  Joint Base Elmendorf-Richardson (JBER) is known to support little brown bat populations which are currently unmonitored. AERC will implement a bat survey on JBER to determine the presence of bats, estimate their abundance, and identify their preferred habitats. Methods pioneered during this survey will give JBER land managers the tools they need to better monitor and, if necessary, protect bat populations on the installation. 

•    Conduct bat monitoring using acoustic bat detection equipment and share data with the Bat Acoustic Monitoring Portal (BatAMP)
•    Improve upon existing monitoring practices by identifying behavioral patterns and vocalizations which are unique to bats in the area.
•    AERC staff will conduct field work, produce written reports, and make recommendations based on the results of the survey.
