NEW HIBERNACULUM FOUND IN ALBERTA
March 6, 2017
On a recent trip to the boreal forest of northern Alberta, BatCaver volunteers have confirmed the use of a cave by Little Brown Myotis bats for hibernation. In this cave, 213 Myotis lucifugus were counted, but it is suspected that more exist. The cave itself is unusual in that it was formed by a light sulphuric acid dissolving the limestone, making the environment fairly inhospitable for humans. Bats were swabbed for samples of DNA and to monitor for signs of white-nose syndrome. Ultrasonic data loggers that record bat activity were deployed, along with temperature and humidity loggers which gather information on the type of cave climate the bats are using at this site. This is the third largest hibernaculum found in Alberta to date.
EDUCATIONAL MATERIALS PRODUCED
The BatCaver program has produced brochures aimed at people visiting caves which explain the risks of inadvertently transporting white-nose syndrome spores from one region to another. It also contains conservation messaging, decontamination protocols for WNS and contacts for further information. These have been sent to tourist caves in western Canada as well as caving organizations. In addition, we have produced signage regarding bat conservation messaging, intended for posting at entrances to bat hibernation caves. Other signage has been produced in consultation with BC Parks, for posting at trailheads to provincial cave parks which has similar conservation messaging. We are also workng with other bat groups across Canada on bat translocation signage. This is regarding the issues around bats being accidentally transported by campers and their vehicles when moving around North America. The concern is regarding moving bats infected with white-nose syndrome to uninfected regions.
WHITE-NOSE SYNDROME CONFIRMED IN WASHINGTON STATE
March 31, 2016
We have just received the unfortunate news that a single bat has been confirmed to have died from White Nose Syndrome, just east of Seattle, Washington State. For cavers in the west, this means that decontamination protocols need to be observed. CLICK HERE for a link to the original press release.

Summary of our first year's activities
In the first year of the program, beginning fall 2015, we have deployed ultrasonic bat detectors to 70 mine and cave sites across British Columbia and Alberta. New bat hibernacula have been identified by our volunteers. Detector retrievals have begun as the snow leaves and bats emerge from hibernation. We would like to acknowledge all our volunteers in this effort: members of the Alberta Speleological Society, BC Speleological Federation and all others who have contributed to the success of this major undertaking. Our 2016 season includes analysis of the data gathered, followed by redeployment of data loggers to new locations in our ongoing effort to identify hibernation sites across western Canada.
