Saving Wisconsin's bats
Bats are are a vital part of many ecosystems. They help control pests and are pollinators and seed-dispersers for countless plants. As predators of biting insects, bats may also play an important role in reducing risk of insect-borne diseases, such as the West-Nile Virus. For now, Wisconsin's bat population is stable. But a deadly fungus is racing through cave-dwelling bat populations in eastern states causing extensive mortality, and it's headed this way.

White-nose syndrome (WNS) is a devastating disease of hibernating bats that has caused the most precipitous decline of North American wildlife in recorded history. It is caused by the fungus Geomyces destructans, and is rapidly spreading through cave bat populations across the country causing unprecedented mortality. Since it was first discovered in 2006, WNS has infected six species of insect-eating bats in the northeastern and southern U.S., causing declines approaching 100 percent in some populations. Estimated losses have exceeded one million bats over the past three years. This syndrome poses a severe threat to all four of Wisconsin's cave bat species.
In February 2006, some 40 miles west of Albany, New York, a caver photographed hibernating bats with an unusual white substance on their muzzles. He noticed several dead bats. The following winter, bats behaving erratically, bats with white noses and a few hundred dead bats in several caves came to the attention of New York biologists, who documented white-nose syndrome in January 2007. Named after the distinctive white growth that appears on the nose and wings of affected bats, as of December 2012, white-nose syndrome (WNS) is only 30 miles from Wisconsin.

Why we should care
Bats are a vital part of many ecosystems and white-nose syndrome has significant environmental, economic and public health implications. Insectivorous bats consume large numbers of agricultural pests, which cost farmers and foresters billions of dollars yearly. Bats play an important role in sustaining many unique and fragile cave ecosystems. For example, bats are the primary source of nutrients in many cave systems, and many cave-obligate species depend on such input for survival. Thus, the loss or significant reduction of bat populations from caves could have cascading affects that impact the status of many other cave species.
Bats of Wisconsin
Of the eight species recorded in Wisconsin, the four cave-dwelling bats are listed as threatened - Big Brown, Little Brown, Northern Long-eared, Eastern Pipistrelle - while four others are on our "watch" list.
There are many volunteer opportunities available to the public. For details, please visit the Wisconsin Bat Monitoring Program
How you can help

You can donate directly to the Wisconsin Bat Conservation Society, an annual membership where groups and citizens can support bat projects in need immediate funding. These funds will be used for white-nose syndrome (WNS) research, landowner support in WNS prevention and control, surveillance, inventory, monitoring, applied management and education about the benefits of bats.
