The northwestern pond turtle (Actinemys marmorata) is one of two turtle species native to Washington. The northwestern pond turtle is listed as endangered by the State of Washington. The range of the northwestern pond turtle extends from the Puget Sound Lowlands in Washington, the Columbia River Gorge in Washington and Oregon, down through western Oregon and California, and south to Baja California. Northwestern pond turtles disappeared from the Puget lowlands by the 1980s, with only a few isolated adult turtles remaining.
