Conservation of endangered Indiana bats (Myotis sodalis) requires knowledge of regional habitat use patterns. I radio-tracked Indiana bats to roosts and foraging areas to document summer habitat use. Sexes selected different roost trees: reproductive females selected maples, whereas males selected elms and other species, but did not use maples. Distribution models based on environmental correlates revealed that soil series was the strongest contributor to niche models. Females selected roosts in silt loams; males selected roosts in muck, silt loam and fine sandy loams. All bats foraged in habitats over fine sandy and gravelly loams. Male roosts and female foraging areas were found near local water body elevations, though males foraged at higher elevations. The niche models suggest that sexes roost and forage separately, but that ranges for these activities overlap. My findings identify habitats selected by Indiana bats thereby enabling more effective conservation for this endangered species.
