Volunteers are needed to turn their vehicle into a “Batmobile,” of sorts, to help collect data on the state’s nocturnal flying mammals.The Iowa Department of Natural Resources and Iowa State University are seeking volunteers for an annual bat acoustic monitoring survey to see how a spreading disease has impacted Iowa’s nine species of bat.“It should help us see additional declines in the population numbers, also we’re hoping we’re going to see a recovery,” said Karen Kinkead, wildlife diversity program coordinator with the Iowa DNR.In 2015, the Iowa DNR’s Volunteer Wildlife Monitoring Program partnered with ISU to create volunteer survey routes in select counties for the bat acoustic monitoring effort.The program was created to monitor bat population patterns being impacted by increased cases of white-nose syndrome, a disease that affects hibernating bats.Caused by a fungus and discovered in North America more than a decade ago, white-nose syndrome has spread rapidly and has been attributed to the death of millions of bats across the country, according to the U.S.
