Status in the Cedar

It is likely that eight of the eleven species of bats listed in the HCP are commonly present in the watershed. These include long-eared myotis, California myotis, long-legged myotis, little brown myotis, Yuma myotis, silver-haired bat, hoary bat, and big brown bat.

To date, Keen’s myotis has only been documented on the Olympic Peninsula in Washington State, and is unlikely to be present in the watershed. Fringed myotis has been documented east of the Cascade Mountains, but its distribution west of the Cascade crest is uncertain, so it may or may not be present in the watershed.

Townsend’s big-eared bats generally require underground habitat such as caves or old mines in which to hibernate and survive freezing temperatures in the winter. No caves have been found in the watershed, but there are a limited number of shallow mines in the old Taylor townsite, located in the far western portion of the municipal watershed, that could provide wintering habitat for this species. This species appears to require a cavern-like structure or room with protection from weather, security from predators, and limited disturbance for use as maternity roost and nursery site. We have not documented this type of habitat within the watershed.

Bat species surveys have not been conducted in the watershed, but ultrasonic acoustic studies have detected large numbers of bats foraging over wetlands, lakes, streams, and within forest canopy gaps.
