At 270,000 acres, Tejon Ranch is the largest contiguous private property in California. Straddling the Tehachapi Mountains, it lies at the convergence of four of California’s 10 major ecological regions: Great Central Valley, Sierra Nevada, Mojave Desert and Southwestern California. Tejon Ranch provides the only corridor for wildlife movements between vast tracts of protected lands.

The diversity of plants and animals found on Tejon Ranch reflects its position as a biogeographic crossroads, where species unique to each of these regions are found together. More than 200 species of birds have been spotted, a third of the state’s native oaks are represented, and more than 60 at-risk plant and animal species are protected on the Ranch's conserved lands.

As California becomes increasingly crowded, protecting its diverse wildlife, while producing the resources needed to live, is critically important. With the Conservancy, the Ranch is now a valuable living laboratory for scholars and scientists. The Conservancy partners with leading universities to engage in research to inform management decisions. These studies will be relevant throughout the Southwest as the Conservancy continues to learn how best to balance the activities of a working ranch, while preserving and enhancing its biodiversity.

Tejon Ranch represents an extremely critical piece of a larger, continent-wide conservation effort to create important and unobstructed corridors for wildlife. Significant public and private conservation investments have been made to create this vital corridor for wildlife because needed habitat is increasingly threatened by land use and climate change.
