Indiana Bat

Endangered Indiana BatThe Indiana bat was first listed as an endangered species in 1967 primarily due to human disturbance during the hibernation period.

Changes to the structure of the cave can result in fluctuating temperature, air flow, and humidity, no matter how slight, and can drastically affect the environment for bats. Indiana bats summer habitat has also been impacted due to the loss of forest, thus losing their summer roost trees and foraging sites. On top of this, pesticides and other environmental contaminants have negatively impacted their drinking water and food source.

Recently identified in 2006, White-nose syndrome has killed over 5.5 million bats in the United States. It is a white fungus often seen on the faces and wings of affected bats. White-nose syndrome has affected many different kinds of bats, and is not restricted to Indiana bats. It was first detected in caves in New York and has since spread to other states. It has not been discovered at Pilot Knob National Wildlife Refuge. The U. S. Fish & Wildlife Service is committed to working closely with other partners to halt the spread of this syndrome and find a solution.  To learn more about White-nose Syndrome visit the Fish & Wildlife Service's national website:
