    Special needs

    This species is generally associated with forests. California myotis use large snags for day roosts. They are occasionally found night-roosting under bridges.

    Limiting factors

    California myotis are patchily distributed and have low reproductive rates. Availability of large snags for roosting may be a limiting factor.

    Conservation actions

    Maintain and create large snags during forest management activities. Complete bridge replacement and maintenance when bats are absent.
