Ecoregions

    Special needs

    Hoary bats are generally associated with forest habitat. They use late-successional conifer forests for roosting. They require abundant insect prey.

    Limiting factors

    Hoary bats have low reproductive rates and are threatened by habitat loss. Migratory behavior increases this species' vulnerability to habitat changes and wind turbine-related mortality.

    Conservation actions

    Investigate data gaps and use results to guide management actions. Implement impact reduction strategies (e.g., operational minimization) at wind energy facilities to reduce fatalities.
