National Wildlife Refuge System Closes Caves
to Slow Spread of White-Nose Syndrome
The U.S. Fish and Wildlife Service’s National Wildlife Refuge System has decided to close caves and mines and implement research and monitoring protocols in a nationwide effort to slow the spread of white-nose syndrome (WNS) in bats. Acting Service Director Greg Siekaniec issued the guidance in a memo dated Sept. 2, 2010.
First documented in New York in 2006, WNS has spread rapidly across the eastern United States, killing more than 1 million bats. Named for the white fungus that appears on the muzzle and other body parts of hibernating bats, WNS is associated with extensive mortality of bats in the Northeast.
Bats with WNS are found to exhibit uncharacteristic behavior during cold winter months including flying outside in the day and clustering near the entrance of hibernacula.
More than half of the 45 bat species living in the United States rely on hibernation for winter survival. Four endangered species and subspecies of hibernating bats in the U.S. are already affected by or are at risk from WNS.
The fungus associated with WNS, Geomyces destructans, has been detected as far west as Oklahoma, and is expected to continue spreading. While the fungus is transmitted primarily by bat to bat contact, biologists suspect it could be transmitted inadvertently by humans. Fungal spores can be transferred from cave sediment to clothing and instruments, and transported to unaffected sites.
The Service is leading a cooperative effort with federal and state agencies, researchers, universities and other non-government organizations to research and manage the spread of WNS.
