Parks Canada is working to combat white-nose syndrome, a lethal fungal infection threatening the bat population in Alberta. Crews are applying a mix of bacteria in bat caves to inhibit the fungus’s growth. Biologist Nina Veselka reported witnessing severe impacts at a Jasper National Park cave, where bat fatalities have surged from three to approximately 69 in recent counts. The fungus, which thrives in cold, damp environments, disrupts bats’ hibernation, leading to starvation as they burn fat reserves prematurely. While the fungus poses no danger to humans, it can decimate up to 98 percent of bat colonies, contributing to a potential local extinction of certain species.
Why It Matters
The spread of white-nose syndrome has been linked to significant declines in bat populations across North America, with millions of bats dying since the disease’s introduction in New York two decades ago. Bats play a crucial ecological role in controlling insect populations, including agricultural pests, which can lead to increased pest outbreaks if bat numbers continue to dwindle. The disease was first detected in Alberta in 2022, and the province has initiated measures, including probiotic treatments, to mitigate its effects. Recovery for bat populations is slow, as they typically reproduce just one pup per year, underscoring the long-term ecological consequences of the infection.
