The Mazama pocket gopher (Thomomys mazama) is a smooth-toothed pocket gopher restricted to the Pacific Northwest. The herbivorous species ranges from coastal Washington, through Oregon, and into north-central California. Four subspecies of the Mazama Pocket Gopher are classified as threatened under the Endangered Species Act of 1973, including T. m. pugetensis (Olympia pocket gopher), T. m. tumuli (Tenino pocket gopher), T. m. glacialis (Roy Prairie pocket gopher), and T. m. yelmensis (Yelm pocket gopher).[4] The Mazama Pocket Gopher is one of the smallest of 35 species in the pocket gopher family.[5]
