Director Bill Mueller and board member Robert Holzrichter participate in acoustic surveys as part of the Wisconsin Department of Natural Resources’ Wisconsin Bat Program.Using devices that detect bats’ ultrasonic echolocation calls, they and other surveyors record bat activity while driving transects in diverse regions of the state.
