(WFRV) – The Wisconsin DNR is calling on volunteers and landowners to help gauge bat population trends this summer as part of the Great Wisconsin Bat Count.
As Wisconsin’s cave bats return to their summer roosts in bat houses, outbuildings, and barns throughout the dairy state, officials with the DNR are calling on residents to help count bats on two separate dates this summer.

Known collectively as the Great Wisconsin Bat Count, Wisconsinites can count bats emerging at sunset on one night between June 6 and 8, and on July 18 and 20.
The June count is known as a “prevolancy” count, meaning it occurs before the newborn bat pups have started flying. The second count in July is after pups have started flying, providing officials with an idea of the increase in the population.
Volunteers are asked to only count on one night during each timeframe, but the more nights the better. Volunteers are also asked to provide information on the roost site and weather conditions.
