Bats and Caves

The mission of the WCS Canada BatCaver Program is to identify and study hibernation sites for bats in Western Canada, using the resources of Cavers and the public to expand our knowledge.  This information is critical to conserving bat populations from threats to their survival such as the disease White Nose Syndrome, which is spreading across North America and will reach Western Canada in a few years.  

Bats play a major role in keeping insects including mosquitos under control, their only food source in this region.  Knowledge is our best defense and we may be able to protect bats against the disease with further research.

Facts

Bats are the primary consumer of night-time insects, including mosquitoes. Have you ever wondered why bats sometimes swoop close to your head?  They may be picking off the biting bugs that you attract!

White Nose Syndrome, a deadly fungal disease of bats, has killed millions of bats in Canada and the US, but has not yet reached Alberta or British Columbia.




Bats are the longest-lived, slowest reproducing mammals for their size.  A little brown myotis who was at least 38 years old was observed in Cadomin Cave in Alberta!  AAAAAAAA    

Protect Bats

Bats are very sensitive to disturbance while hibernating. If you see hibernating bats, leave the area immediately.

Clean Gear

Decontaminating your gear between caving trips can prevent the spread of WNS.

Find Bats

Install a bat monitoring device in a cave or mine when you go caving.

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.  For cavers in the west, this means that decontamination protocols need to be observed.  For more information, CLICK HERE.

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.  In addition, we are currently working on educational signage for bat hibernation sites and provincial responses to the new WNS outbreak just south of the border, in conjunction with government agencies.  We will also soon be releasing an educational brochure.  Thanks to all who have contributed and we look forward to a productive 2016 season!

White Nose Syndrome (WNS) is a fungal disease that has caused up to 100% bat mortality in cave hibernacula in Eastern Canada and United States. The longer the West can remain WNS-free, the more time there is to develop critical conservation strategies for vulnerable bat species.
