These surveys are done as part of the Wisconsin Bat Program and coordinated locally by the North Lakeland Discovery Center. We conduct the surveys by taking a slow ride around the perimeter of the lake after dark while using a handheld bat detector. Each species of bat has a different high-frequency call which can be heard by the detector. By looking at the frequency, shape and other characteristics of calls, the software in the detector can identify the species of bat that was recorded.
Bats are fascinating animals that are vital to the environment. They eat tons of insects nightly, saving farmers billions of dollars in pest control every year. They benefit our forests by pollinating a variety of flowering plants and spreading seeds that grow new trees. It’s good to know that Lake of the Falls supports such a healthy population of bats! Just one more reason to love our lake.
