After two bats in Boulder County tested positive for an aggressive fungal infection, state wildlife officials are bracing for a “devastating” blow to Colorado’s native bat population. The disease could decimate bat colonies, and in its wake, leave long-lasting impacts on the state’s agricultural economy and local ecosystems.
White Nose Syndrome
Named for the visible appearance of a white fungus growing around a bat’s muzzle, the fatal White nose syndrome is spread through bat-to-bat contact. It’s typically contracted during hibernation, causing the bats to wake up and then starve to death. Since its discovery in New York in 2006, WNS has killed millions of bats across North America. The disease is still not well-understood by scientists and has no known cures or treatments.
Why It Matters
Bats are a critical pollinator species and play crucial roles in insect control, delicate cave ecosystems, and the larger food chain. Experts estimate that bats contribute some $3 billion to the country’s agricultural economy by eliminating the need for pesticides.
How You Can Help
WNS does not appear to infect humans or other animals. However, both can carry the disease and introduce it to non-infected areas. You can help limit the spread by:
- Staying out of closed caves or mines
- Thoroughly decontaminating gear and clothing after being in caves
- Report dead or injured bats to CPW by 303-291-7771 or emailing wildlife.batline@state.co.us
