Why did the Service Propose Listing the Northern Long-eared as Endangered?

The northern long-eared bat was once a common resident of forests from the Atlantic coast and west as far as eastern Wyoming and Montana. Unfortunately, this particular bat is one of the species hardest hit by the disease, white-nose syndrome. In forests of the Northeast, population declines have been dramatic in a very short time. Declines of up to 99 percent have been documented through hibernacula surveys and substantiated by summer surveys. The range of the northern long-eared bat extends into 37 states and white-nose syndrome has spread to 25 of those states, with the fungus that causes the disease documented in an additional 3 states. Based on surveillance and research since white-nose syndrome symptoms were first seen on bats in 2006, we expect that white-nose syndrome will spread throughout this bat’s range and that impacts will be the same as those documented in areas already affected by white-nose syndrome.

Proposal to List as Endangered

The U.S. Fish and Wildlife Service held three public information webcasts in August 2014 to provide information and answer questions about our proposal to list the northern long-eared bat as endangered under the Endangered Species Act.

The 1-hour information sessions included a presentation and facilitated question-and-answer session.
