Last year, the fungus that causes white-nose syndrome (WNS) in bats was detected in Grand Forks, BC.  This winter and spring, the BC Community Bat Program, in collaboration with the Province of BC, is asking the public for help in the effort to detect and prevent the spread of WNS. Residents are urged to report any bat activity observed in winter and any sick or dead bats found before May 31st.

There have not been any bats with WNS found to date in BC, but biologists are concerned that the arrival of WNS is imminent. First detected in New York State in 2006, the disease continues to spread, with detections in western and central Washington and in south-central Alberta.

The fungus does not cause disease in humans and pets, but white-nose syndrome has devastated North American bat populations. The fungus attacks bats while they are hibernating, growing on their faces to give an appearance of a white nose. Bats often wake to clean the fungus from their skin. This uses valuable energy, and eventually the bats die from starvation.

Across North America, millions of bats have been killed, and seven of our 15 BC species could be severely affected by the disease.  The Little Brown Myotis and the Northern Myotis are both listed as Endangered in Canada due to WNS.  Though there is not yet a proven cure for WNS, several promising treatment options are being developed, and it may be possible to mitigate the effects of this wildlife health crisis.

If you find a dead bat or have sightings of winter bat activity, please report to the B.C. Community Bat Program online at, via email at, or by calling 250-539-2535.  All live bats should be left alone—keep your distance, snap a photo, and report it to the B.C. Community Bat Program coordinator on Mayne Island, Michael Dunn. If you must move a bat, visit for advice, and never touch a bat with your bare hands.

In partnership with the BC Ministry of Water, Land and Resource Stewardship, the BC Community Bat Program provides information and promotes local stewardship and citizen science. The program is supported by funding from the Habitat Conservation Trust Foundation, Forest Enhancement Society of BC, the Habitat Stewardship Program, and the Province of BC.
