Agricultural and residential development, as well as recreational activity, has altered the wildlife community of the Monument. Mule deer are common. Red foxes, coyotes, badgers, cottontail rabbits, and yellow-bellied marmots are upland residents. River otter, beaver, muskrat, mink, and other furbearers are found in and around Hagerman’s ponds, marshes, and waterways.

The zebra-like horse fossil Equus simplicidens was originally named Plesippus shoshonensis by Dr. Gidley, Smithsonian paleontologist, who led the 1929 excavation at Hagerman. He felt the fossil was different enough to represent a new species distinct from any other fossil horses.
