Green Bay Appleton, WI, October 24, 2026 —
The 12th annual Great Wisconsin Bat Count found that four of Wisconsin’s eight bat species remain threatened, according to the information provided about the count. More than 150 scientists and volunteers took part, monitoring over 20,000 bats.
The findings also highlighted continued concern about declining bat populations, particularly in connection with white-nose syndrome. The summary of the count does not identify which four species remain threatened or provide population figures for individual species. It also does not state how the number of bats monitored compares with earlier counts.
The count’s results offer a broad picture of the status of the state’s bat species, but the available details do not specify when or where monitoring took place, how the bats were counted, or what changes were recorded from one year to the next. No information was provided about the organizations involved, the count’s detailed methods, or any specific measures being taken in response to the findings.
White-nose syndrome is identified in the summary as a particular concern associated with declining populations. The information provided does not describe the syndrome’s effects in Wisconsin or quantify how much it has contributed to population changes. It also does not say whether the monitored bats represented all eight species.
The reported figures—more than 150 participants and over 20,000 bats monitored—describe the scale of the annual count. However, the count summary does not provide a full breakdown of results or additional data that would show how the status of Wisconsin’s bat species has shifted over time.
