The state of Ohio and New Brunswick, Canada can now be added to the growing list of affected states and provinces in North America. Maryland also identified another affected site, an abandoned mine that bats adopted for hibernation. Here is the most recent WNS map.

A great friend to bats, Cal Butchkoski of Pennsylvania's Game Commission, created and updates these maps. Thanks Cal! We know it's very sad to be the historian of our bats' disappearance.
