Weighing less than a pound and spanning about 10 inches, the mouse-eared Indiana bat has been winging its way into recent Hall County transportation projects. And now the federally protected creature plays a role in the Gainesville-based Chattahoochee-Oconee National Forests’ update of its 2004 Land and Resource Management Plan. The Forest Service proposes to add several requirements, including that trees known to have been used as roosts by Indiana bats are protected from cutting or other disruptions “until they are no longer suitable as roost trees.”
