White-Nose Bat Syndrome

Since 2006, a newly discovered disease called White-Nose Syndrome has killed about 1 million bats in North America.  The disease is believed to originate from a cold-loving fungus that spreads among hibernating bats while in their caves.

While no cases of White-Nose Syndrome have been observed in Iowa yet, DNA of the fungus that causes the disease was detected from a swab sample of a bat collected at Maquoketa Caves in March of 2012. DNR experts have been monitoring bat populations, and state parks staff is educating the public while taking preventative measures to slow its potential spread.
