Quercus durata, Leather Oak

by Doreen Smith

Leather oak, Quercus durata, is common and nearly always found on serpentine-derived soils. In Marin this scrub oak grows in the chaparral of Mt. Tamalpais, Big Rock Ridge and Mt. Burdell.
“Our other scrub oak, Quercus berberidifolia, is very uncommon here, not on serpentine, and only easily discovered near Gold Grade fire-road halfway up the San Pedro Mountain behind Dominican University, San Rafael.
