Holy Bat Fungus, Cave Man

Posted by Anonymous on May 1, 2009

Bats have been dying at alarming rates from what scientists call “white-nose syndrome,” so-named because it appears as a white powder on the face and wings of hibernating bats.

The problem was first spotted in New York and within two years has spread to caves in West Virginia and Virginia. There’s no evidence the fungus is harmful to people.

Researchers believe the fungus is spread from bat to bat, but they have not ruled out the possibility that humans tromping from cave to cave might help to transmit it on their shoes and equipment, said Dennis Krusac, a biologist with the service’s Southern region.

“We don’t have the answers at this point,” he said. “If we have answers in a year or sooner, we can open them back up.”

Forest Service biologist Becky Ewing said an emergency order was issued last week for caves in 20 states from Minnesota to Maine. A second order covering the Forest Service’s 13-state Southern region should be issued later this month.

The sites will be closed for up to a year, she said.

The orders follow a March request by the U.S. Fish and Wildlife Service for people to voluntarily stay out of caves in 17 states.

Biologists are concerned the fungus could wipe out endangered Indiana, Virginia and Ozark big-eared and gray bats.

Bats play a key role in keeping insects such as mosquitoes under control. Between April and October, they usually eat their body weight in bugs per night. The loss of 500,000 bats means 2.4 million pounds of bugs aren’t eaten in a year, Ewing said.
