Decontamination Recommendations

We are recommending that people visiting caves or mines in BC and Alberta decontaminate their gear when moving between regions. This involves placing your gear in 60oC water for 20 minutes to kill the spores from the WNS fungus. On the coast where spread is expected to occur sooner, regions for our purposes are North Vancouver Island, South Vancouver Island, Fraser Valley. In the rest of BC and Alberta, if you are moving significant distances to cave, particularly if you are meeting for caving expeditions, please decontaminate for these trips and afterwards. If you are coming from WNS-positive regions, these protocols are extremely important. The best practise is to not bring gear from contaminated regions and to acquire it from the destination travelled to. Most important is suits, gloves, footwear, packs and harnesses - in short, anything that accumulates dirt in its fibres. This notice is subject to revision as government responses are formulated. In short, use common sense and please do not introduce this disease to new regions.

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.

NEW HIBERNACULUM FOUND

February 2017

On a February 2017 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.

In our partnering with the general public, biologists and the caving community, other smaller newly discovered hibernation sites have been brought to our attention.  These include sites in British Columbia in the regions of these communities:  near Victoria; Port Alberni; Greenwood;  Dawson Creek; and Hudsons Hope.  Many other old mine sites have been found to contain large numbers of hibernating bats, primarily in southern BC.

NEW EDUCATIONAL MATERIALS

February 2017

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 (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.
