Big Brown Bat Promo 512x219

The role that bats play in the world's ecosystems can not be overstated. Vital keystone species, bats impact every aspect of our environment. These fascinating animals are major pollinators and seed dispersal agents. They also provide significant insect control and nutrient cycling. These ecosystem services contribute greatly to human health and economy.

    In 1996 and 1997, 536 bats representing 10 species were captured on Turnbull during hundreds of hours of mist netting over wetlands and use of harp traps. Species captured included; the big brown bat, hoary bat, silver-haired bat, California myotis, small-footed myotis, long-eared myotis, little brown myotis, fringed myotis, long-legged myotis, and Yuma myotis.  In 2000, a Townsend's big-eared bat was captured on the refuge bringing the refuge species count to 11.

    The big brown bat is one of the larger bat species that frequent the refuge. The females roost in maternity colonies as large as 100 individuals. Refuge research found these roosts are in cavities in snags and dead tops of ponderosa pine, under bark of dead trees and in buildings. They will use several roosts during a breeding season moving every few days.

  • Long-Eared Myotis

    Long-Eared Myotis 150x118

    One of the several species of the genus Myotis (mouse-eared bats). Refuge research on this species found maternity roosts in crevices of basalt outcrops or isolated boulders found throughout the Channeled Scablands. Maternity colonies are typically small consisting of less than 6 individuals. Similar to big brown bats these colonies move to a new roost every few days.
