A temporary scrub type after heavy cutting and repeated fires, Bear Oak is replaced by taller pines and oaks. The Latin species name, meaning holly leaf, refers to the foliage. It is called Bear Oak, reportedly because only bears like the very bitter acorns. Bear oak is a transition species that depends upon stand disturbance. Fire promotes this species.
