Bats, like the federally endangered Indiana Bat and the threatened Northern Long-eared Bat, use trees to roost.
Key characteristics of a roost tree are exfoliating bark, cracks, and crevices found on dead and dying trees.
We conduct walking surveys of natural areas in the Illinois Tollway region to identify potential roost trees.
Knowing where these trees are can help direct more intensive surveys and inform land managers of areas to protect.
