December 19, 2013 (San Diego) – San Diego Gas & Electric (SDG&E) and the U.S. Forest Service have partnered to preserve and protect 448 acres between El Cajon Mountain and the El Capitan Reservoir. Known as Oak Ridge Ranch, the property is now National Forest system land donated by SDG&E.

The partnership at Oak Ridge Ranch protects native Engelmann oak trees that only grow naturally in a narrow band that stretches along the mountain foothills of Southern California and Baja California, Mexico. The Engelmann oak is an indicator species, which means that when this beautiful evergreen oak thrives, so too does the surrounding forest ecosystem.
