Indiana bats were found in a variety of plant associations in a southern Iowa study. Riparian areas were dominated by eastern cottonwood, hackberry ("Celtis occidentalis"), and silver maple ("Acer saccharinum"). In the forested floodplains, the dominant plants included black walnut ("Juglans nigra"), silver maple, American elm ("Ulmus americana"), and eastern cottonwood. In undisturbed upland forest, the most common plants were black oak ("Quercus velutina"), bur oak ("Q. macrocarpa"), shagbark hickory ("Carya ovata"), and bitternut hickory ("C. cordiformis"). Black walnut, American basswood, American elm, and bur oak dominated other upland Indiana bat sites.
