An alarming fungal disease is threatening Colorado’s bat populations, as officials confirm recent cases of white-nose syndrome in Boulder County. Previously, the fungus responsible for the disease had been detected within the state, but these new cases mark the first instance of infected bats found in Colorado.

In February, a sickly bat was discovered on a public bike path in Longmont. Colorado Parks and Wildlife (CPW) reported the bat had brittle wings, inhibiting its ability to fly. The bat tragically tested positive for white-nose syndrome, a disease responsible for the deaths of millions of bats across North America.

Just two weeks later, a second infected bat was found near Boulder. This growing crisis highlights the precarious situation of Colorado’s native bat species.

A Deadly Fungus

White-nose syndrome derives its name from the tell-tale white fungus that grows on the muzzles, ears, and wings of hibernating bats. This fungus disrupts their hibernation cycle, causing them to awaken prematurely and deplete their crucial fat reserves. The result is often starvation or death from exposure.

“White-nose syndrome is devastating to bat populations,” explains a CPW wildlife biologist. “These bats play a vital role in our ecosystem, controlling insect pests and pollinating plants. This disease poses a significant threat to their survival.”

Colorado on Alert

The first Colorado case of a bat infected with the white-nose syndrome fungus was documented in March 2023. Since then, wildlife officials have been diligently monitoring bat populations and habitats for signs of the disease. These recent cases in Boulder County signify the expanding range of white-nose syndrome within the state.

CPW is urging the public to report any sightings of sick or dead bats immediately. While the disease is not transmissible to humans, it can easily spread amongst bat colonies. By reporting potential cases, citizens can support efforts to track the disease and aid in potential conservation measures.

How You Can Help

• Report sightings: If you find a dead or visibly sick bat, contact Colorado Parks and Wildlife. Do not handle the bat yourself.
• Protect bat habitats: Bats rely on caves and old-growth forests. Support conservation efforts, and minimize disturbances to these sensitive habitats.
• Learn more: Educate yourself about the importance of bat populations and the dangers posed by white-nose syndrome.

The future for Colorado’s bats remains uncertain as white-nose syndrome continues its spread. By taking action and staying informed, citizens can play a crucial role in protecting these vital creatures.
