Endangered Status The Rice Rat, a subspecies of the Marsh Rice Rat, is on the U.S. Endangered Species List. It is classified as endangered in Florida, where it lives in the westerly Keys. This rat historically lived in salt marsh habitat, and its decline came as its habitat was destroyed to make way for residential and commerical development in the Florida Keys. Much of Rice Rat's remaining habitat is within the National Key Deer Refuge, and thus is protected.
