Sitting near the San Andreas Fault, it encompasses a remarkable diversity of plant and animal life. It contains Searsville Dam and Upper, Middle, and Lower Searsville Lakes as well as the serpentine grasslands on Jasper Ridge and many other ecosystems – in fact, the majority of non-coastal ecosystems in California!
