The northern long-eared bat is one of the species of bats most impacted by the disease white-nose syndrome. Due to declines caused by white-nose syndrome and continued spread of the disease, the northern long-eared bat was listed as threatened under the Endangered Species Act on April 2, 2015. We also developed a final 4(d) rule, which published in the Federal Register on January 14, 2016. The 4(d) rule specifically defines the "take" prohibitions.

Bats are important to our nation’s ecology and economy, eating tons of insects nightly and providing a natural benefit to farmers and foresters. Some research estimates that bats provide at least $3 billion annually in economic value.


Habitat: Hibernates in caves and mines - swarming in surrounding wooded areas in autumn. During late spring and summer roosts and forages in upland forests.


Lead Region: 3

Section 7 Consultation

Section 7 of the Endangered Species Act directs all Federal agencies to work to conserve endangered and threatened species and to use their authorities to further the purposes of the Act. Section 7 of the Act, called "Interagency Cooperation," is the mechanism by which Federal agencies ensure the actions they take, including those they fund or authorize, do not jeopardize the existence of any listed species.

Life History

Northern long-eared bats spend winter hibernating in caves and mines, called hibernacula.  They use areas in various sized caves or mines with constant temperatures, high humidity, and no air currents.  During the summer, northern long-eared bats roost singly or in colonies underneath bark, in cavities or in crevices of both live trees and snags (dead trees).

White nose syndrome is an illness that has killed over a million bats since 2006 when dead and dying bats, with the distinctive "white nose," were first observed. "White nose" refers to a ring of white fungus often seen on the faces and wings of affected bats.

Bat House Instructions

As hollow trees are cut down, bats need bat boxes to survive. This is especially true in April to August when females look for safe and quiet places to give birth and raise their pups. Both the mothers and newborns are sensitive to disturbance. Install a bat box anytime, but late winter and early spring is best.
