A lethal fungus that has devastated bat populations throughout North America is spreading in Alberta. White-nose syndrome has been identified in the Rocky Mountains of Alberta for the first time, marking a significant expansion of the disease since its initial confirmation in the province in 2024. Over 6.7 million bats in North America have perished from the infection since 2006, according to the Center for Biological Diversity. The disease, caused by a fungus that infiltrates bats’ skin during hibernation, disrupts their sleep, leading to starvation, dehydration, and eventual death.
The fungus responsible for white-nose syndrome was first detected in Alberta in 2022, with the confirmation of symptoms by the province following two years later. Recent surveys by the provincial government and Wildlife Conservation Society Canada discovered white-nose syndrome in three caves in the Rockies, including Cadomin and Wapiabi caves, which have been closed to the public since 2010 to prevent the spread of the disease.
Lisa Wilkinson, a provincial bat specialist with Alberta Environment and Protected Areas, expressed concern over the alarming decline in bat populations due to the disease. While the complete elimination of the disease is unlikely, efforts are being made to mitigate its impact through the application of probiotics to bat habitats. The province has reported positive outcomes from the probiotic treatment, showing reduced fungal presence on bats and evidence of bats transmitting the probiotic amongst themselves.
Two bat species in Alberta, the little brown bat and northern myotis, are classified as endangered by the federal government. Wilkinson emphasized the vulnerability of hibernating bats to white-nose syndrome, anticipating further population declines. The public is encouraged to contribute to bat conservation efforts by reporting bat roosts on their properties and providing bat guano samples for testing to aid in monitoring and treatment strategies.
Efforts to raise awareness and appreciation for bats are essential in preserving these vital species. The Alberta Community Bat Program plays a crucial role in promoting bat conservation and enlisting public support to safeguard bat populations from the devastating impacts of white-nose syndrome.
