Vegetation at the Ranch is typical of lower elevational southern California: mosaics of grassland, oak woodland, riparian woodland, coastal sage scrub, and chaparral. Wildlife species include fence lizards, canyon tree frogs, red-shouldered hawks and mountain lions. All native habitat and wildlife is becoming rare in southern California and the Ranch protects some especially endangered vegetation types such as coastal sage scrub and native perennial grassland as well as species such as many-stemmed dudleya (a plant) and the California gnatcatcher (a bird).
