Impacted Bats

White-nose syndrome (WNS) predominantly affects hibernating bats. More than half of the 47 bat species living in the United States and Canada rely on hibernation for winter survival.

Currently, 12 bat species, including two endangered species and one threatened species, have been confirmed with white-nose syndrome in North America. The causative fungus, Pseudogymnoascus destructans (Pd), has been found on an additional nine species (including two endangered species and encompassing two endangered subspecies) without confirmation of the disease.

Latest update: In Spring 2025, the pallid bat was added to the list of Pd-positive species in North America as a result of Pd-positive samples collected during surveillance work by Texas Parks and Wildlife Department.
