Bat detector

Within the Tollway region, the mammal species of concern are bats. We have been assessing bat populations within the Tollway corridor using:

acoustic monitoring
– bat roost tree surveys
– mist netting


I-90 post construction
– IL53-IL120 extension assessment
– IL Rt 390 extension
North Chicago Wetland Mitigation Site

UBAP Mammalogist Tara Hohoff also heads up the Illinois Bat Conservation Project.

Highlights from our work:

  • Four species of bats were able to be detected through acoustic monitoring at the North Chicago Wetland Site
