Deadly bat disease fungus confirmed in key tourist destination as officials warn of impacts

The fungus, Pseudogymnoascus destructans (Pd), was discovered by officials during routine monitoring of the Lake Mead National Recreation Area, according to an NDOW press release.

The disease shows visible white fungal growth on infected bats' muzzles and wings.

"It spreads easily from bat to bat during hibernation, and humans unintentionally spread it from cave to cave by tracking the spores on their shoes," said Siegel.

He added, "Fungus likes cold blood, and the bats cool down when they are hibernating. But the fungus forms a fuzz on their wings and muzzles. As they wake up from hibernation, they start behaving strangely and often die of starvation."

"Nevada's bats are incredibly important, and this fungus could have serious implications for their conservation," said NDOW specialist Jonathan Young.

"We knew it was a matter of time before Pd arrived in Nevada, and we have been vigilantly surveying bats for many years now, not only for this fungus but also to track their population trends," said Young.

Young said officials are continuing to monitor the situation.

They're working to reduce the spread of the fungus with equipment sterilization, habitat protection and public education, he indicated. 

Officials are urging visitors to avoid entering abandoned mines for their own safety, and to prevent unintentionally carrying the fungus to new bat sites.

The park is open year-round, located in southeastern Nevada and northwestern Arizona.
