First Colorado bat hit by deadly fungal disease
A deadly fungal disease called white-nose syndrome has infected a bat in Colorado for the first time, state wildlife officials announced Monday.
Why it matters: It could be devastating for our local bat populations. The disease has decimated over 90% of three North American bat species in under 10 years, according to the U.S. Geological Survey.
- Nationwide, bats save more than $3 billion annually in crop damage and pesticide costs by eating insects, the U.S. Fish and Wildlife Service estimates.
Details: On March 29, an adult female Yuma bat at Bent's Old Fort National Historic Site in southeastern Colorado, was found on the ground and unable to fly.
- Wildlife officials noticed the bat had a white powdery substance on its forearms and chose to euthanize it for testing.
- Lab tests confirmed wing lesions characteristic of white-nose syndrome. The bat also tested positive for the fungus that causes the fatal condition.
By the numbers: At least 13 of Colorado's 19 native bat species are susceptible to the disease, according to the state's parks and wildlife department.
Of note: Last summer, federal wildlife researchers found the presence of the fungus at the same location, as well as in Baca, Larimer and Routt counties — but no bats captured in those areas showed signs of the disease.
What they're saying: After last year's discovery, "we expected this news was inevitable in a year or two, given the experience in other states as white-nose syndrome has spread westward," Tina Jackson, Colorado Parks and Wildlife's species conservation coordinator, said in a statement.
- "We've been monitoring for the fungus for a number of years and this is the same pattern seen in other states," Jackson added.
The big picture: White-nose syndrome has been documented in 39 states and seven Canadian provinces since first being detected in New York in 2006.
What's next: Colorado Parks and Wildlife is partnering with federal agencies to continue to study bat species and assess the spread of the syndrome this year.
- A $2.5 million federal grant was also awarded last month to the University of Wisconsin-Madison to fund research for a cure.
Threat level: The fungus doesn't affect humans or pets — but it can be spread to other bats by gear and clothing that comes in contact with places they dwell, like caves.
Wildlife officials recommend:
- Avoiding closed caves and mines
- Reporting dead or sick bats to CPW by calling 303-291-7771 or emailing [email protected]
- Decontaminating footwear and all cave gear before and after touring caves and other places where they live
