Ecoregions

    Special needs

    Fringed myotis require forest habitat. They use large snags and rock features for day, night, and maternity roosts, and caves and mines for hibernacula. They feed primarily on beetles. They occasionally use bridges for night-roosting.

    Limiting factors

    Fringed myotis are patchily distributed and locally uncommon. They are vulnerable to disturbance at roosts. Reduction of large snags and low reproductive rates may also be limiting.

    Conservation actions

    Use gates and seasonal closures to protect known hibernacula. Retain and create large-diameter hollow trees and large-diameter, tall, newly-dead snags during forest management activities.
