Driving Survey Summaries

In 2013, the Wisconsin Bat Program expanded its offering of bat surveying opportunities by adding 38 predetermined driving bat surveys (transects). These reports summarize the methods and results from the driving survey transects that were conducted in their respective years and compares the results to the previous years' data.
