LG&E and KU supports research intended to help boost the population of the endangered Indiana bat. The company installed 10 utility poles several years ago that are used as artificial roosting structures at Fort Knox. The project is a coordinated partnership that includes Copperhead Environmental Consulting, the United States Fish and Wildlife Service, Fort Knox and LG&E and KU.
The utility poles were fitted with artificial bark to supplement and eventually replace the existing roost trees over time. At one time, more than 150 bats were counted emerging from just one of the installed poles.
