Located adjacent to the Riverside
campus, the Box Springs Reserve lies on a steep and rugged
granitic slope near the top of Box Springs Mountain, in
a transitional zone between coastal sage scrub and chamise
chaparral. A cold spring on the adjacent land gives rise
to freshwater seeps and an intermittent stream. Rich in
vertebrates, the reserve hosts nineteen species of reptiles,
including three rare species: the coast horned lizard
(Phrynosoma coronatum), the orange-throated whiptail (Cnemidoporus
hyperythrus), and the red diamond rattlesnake (Crotalus
ruber). Sixteen species of mammals inhabit the reserve,
including the Pacific kangaroo rat (Dipodomys agilis),
mountain lion (Felis concolor), and mule deer (Odocoileus
hemionus). Also observed on site are over eighty-five
bird species. Soaring and hunting on the updrafts are
many raptors, such as golden eagle, turkey vulture, red-tailed
hawk, white-tailed kite, northern harrier, and American
kestrel. Other avian species frequently seen are white-throated
swift, Anna’s hummingbird, rock and canyon wrens, lazuli
bunting, western meadowlarks, and rufous-crowned, black-chinned,
and sage sparrows. Fire occurs fairly frequently in this
area. The reserve burned most recently in 1993, but the
opportunities for research and instruction remain undiminished.Selected
