In the winter of 2006-07 New York Department of Environmental Conservation found approximately 10,000 bats of the genus Myotis (little brown bats, M. lucifugus, and Indiana bats, M. sodalis) dead and dying in four caves in New York. Since 2006, white-nose syndrome (WNS) has killed millions of bats in eastern North America, including several Myotis species, Perimyotis subflavus (Tri-colored bat), and Eptesicus fuscus (big brown bat). WNS is currently confirmed in 22 states and 5 Canadian provinces, as well as is suspected in 2 additional states. In March 2011, the first case of WNS was confirmed in an abandoned mine in Lawrence County, Ohio. Currently, 16 counties in Ohio have been confirmed as WNS positive to include Lawrence County in 2011, 5 counties added in 2012 (Geauga, Summit, Cuyahoga, Portage, and Preble), and 10 counties added in 2013 (Medina, Jefferson, Union, Wayne, Ashland, Athens, Clinton, Madison, Warren, and Sandusky).
