The “lone oak” is a sign of an unhealthy habitat. There should be many oaks of various ages.

The land was once rich, pristine oak and riparian forest, but years of over-grazing sheep and cattle ranches changed the land. Foraging, domestic animals prevented young seedlings from reaching maturity, changing the under story of the remaining trees and replacing the native perennial grasses with annual European grasses and mustard – which gave the state the nickname of the Golden State.
