Knowledge of the diversity and abundance of vertebrates in relatively undisturbed oak woodlands could be used as a baseline for evaluating natural and human-caused perturbations. High numbers of terrestrial vertebrates were found in well-structured oak woodland at a study site in the Central Coast region. Within classes of terrestrial vertebrates, woodrats, dark-eyed juncos and slender salamanders exhibited the strongest habitat associations. Dense oak woodlands with shrubby understory and downed woody material supported the greatest numbers of vertebrate fauna.
