If the bat is added to the endangered species list, people would have to be more careful about working around them. Public comments are already pouring in from power companies worried about “vegetation management,” or tree cutting. If it's listed, utilities and other users would still be able to do what they need to do, but differently. Maybe they could trim trees in the winter when the pups aren’t there, Sullins says. The agency will decide by April 2 whether the bat will be listed.
