Bats live mostly out of sight and out of mind. But their falling numbers are a reason to look up and worry, scientists say

The elusive winged mammals who make special appearances in decorations and throughout popular culture during the fall are under increasing threats across the state and the Midwest, the victim of a stubborn and spreading disease, shrinking natural habitat and a growing wind turbine industry. And with new changes to the Endangered Species Act, scientists and environmental advocates fear additional species of bats may be under siege from encroaching development and a changing, warming climate.

Recent surveys find few of once-common bat species

Although the Indiana bat is listed as federally endangered, or in danger of becoming extinct, the Illinois Bat Conservation Program (www.illinoisbats.org) researchers have netted more of these bats than the once common little brown bat, which is not protected, and the northern long-eared bat, which is a threatened species at risk of becoming endangered.

Illinois bats face increasing threat from wind turbines

s if white-nose syndrome wasn’t enough, the nation’s bats have another problem: wind turbines that are becoming increasingly more common on the American landscape. For two months, Paul Cryan, a research scientist for the U.S. Geological Survey, set up thermal video surveillance cameras to find out why up to 900,000 bats are killed by windmills each year.

Wind turbines and migratory birds: A serious problem?

Wind turbines are responsible for the deaths of between 10,000 and 40,000 birds each year, according to the American Bird Conservancy. Debate over the significance of the threat turbine blades pose to migratory birds is about as old as the concept of wind farms themselves. It began in Altamont Pass, Calif., site of one of the first U.S. wind farms, where there were more than 4,000 turbines. Hundreds of bird carcasses were found on the farm grounds, leading bird conservationists to propagate information that wind turbines were inherently deadly to birds.

New studies of turbines' impact in the wind

Some say counting carcasses isn't enough. That's why Illinois is changing the way it wants studies of wildlife around wind farms to be performed as more of the clean energy installations are planned around the state. Previous research has been based almost entirely on mortality counts, the process by which bird and bat carcasses are scooped up early in the morning within a several hundred foot radius of wind turbine bases. But studies now are aiming to determine a more long-range impact on avian and terrestrial creatures by examining how animals react to the sudden presence of a vertical structure soaring as high as 450 feet into the sky. The shift in practice comes as other mortality studies are under way in the area, but only a few have been completed in the state. ..."It's unfair to assume, I think, that there's no environmental effects from wind (energy)," said Keith Shank, an impact assessment specialist with the DNR. "Until we get some firm data, the problem is, people are making multimillion-dollar investments with insufficient information."

Study puts focus on bird deaths by wind turbines

Despite proof that birds and bats are being killed by the rotating blades of wind turbines, a new state report says more studies are needed to determine if anything should be done about it. ...But, the report did not call for any immediate action by the state. ''Until the impacts are better understood, regulatory action for wildlife protection is not recommended,'' the report noted.
