The salt marsh harvest mouse, also known as the red-bellied harvest mouse and sometimes called the salt marsh harvest mouse, is an endangered rodent endemic to the San Francisco Bay Area salt marshes in California. The two distinct subspecies are both endangered and listed together on federal and state endangered-species lists. The northern subspecies is lighter in color and inhabits the northern marshes of the bay, and the southern subspecies lives in the East and South Bay marshes. They are both quite similar in appearance to their congener species, the Western harvest mouse, R. megalotis, to which they are not closely related. Genetic studies of the northern subspecies have revealed that the salt marsh harvest mouse is most closely related to the plains harvest mouse, R. montanus, which occurs now in the Midwest. Its endangered designation is due to its limited range, historic decline in population and continuing threat of habitat loss due to development encroachment at the perimeter of San Francisco Bay.
