Tanoak
Notholithocarpus densiflorus

Tanoak is a stately evergreen oak relative of the Pacific Coast, with leathery leaves and acorns that were a staple food for Indigenous peoples and remain vital wildlife mast. (Susceptible to sudden oak death.) The acorns were leached of bitter tannins over months in a stream or swamp before grinding into flour.
