The Washington Department of Fish and Wildlife (WDFW) lists the Townsend’s ground squirrel (Urocitellus townsendii) as a “State Candidate” (WDFW 2012). These animals are important to the shrub-steppe ecosystem for many reasons. They serve as a food source for many mammals such as badgers and coyotes and fall prey to predatory birds such as hawks, falcons, and owls. The ground squirrel diet consists of a variety of foods including seeds, which contributes to native plant seed dispersal. The process of digging burrows helps aerate the soil and provides burrows for other species including burrowing owls (Sato 2012). Their decline is due to the loss of suitable habitat and isolation of their communities through fragmentation. Townsend’s ground squirrels can be difficult to monitor due to their concealed underground lifestyle and short seasons of activity.
