Map Satellite Several natural springs, some of which flow throughout the year, make this area biologically unusual in the region. The availability of water permits a greater diversity of plants and animals than would otherwise be possible. Vegetation is primarily coastal sage scrub, with buckwheat, Eriogonum fasciculatum, California sagebrush, Artemisia californica, sage, Salvia sp., and Encelia sp. Some juniper, Juniperus californica, is present. Thus far, at least 2 species of amphibians, 14 of reptiles, 109 bird species and 19 of mammals have been observed on the Reserve. Among the more noteworthy species are the San Diego horned lizard, Phrynosoma coronatum blainvillei, the orange-throated whiptail lizard, Cnemidophorus hyperythrus, California black-tailed gnatcatcher, Polioptila melanura, gray fox, Urocyon cinereoargenteus, longtail weasel, Mustela frenata, and the endangered Stephen's kangaroo rat, Dipodomys stephensi. Much of the area is on a granitic ridge, the top of which is relatively flat. There are numerous rock outcrops scattered throughout the Reserve. Integrity: There has been some impact by domestic animals but, in general, the area is relatively undisturbed. Use: Research, educational. May 1981
