Over most of the range, acorns fall in October. A variety of mammals and birds eat them, including the acorn woodpecker, California scrub jay, yellow-billed magpie, and California ground squirrel. The acorns are also attacked by bruchid beetles, but can survive moderate levels of infestation. Surviving acorns all germinate in their first winter, and none remain by mid-winter. The acorns are medium to dark brown and range from two to three centimeters (0.8–1.2 inches) in length. The caps have deep stippling and are found most often as singlets, but occasionally as doublets. The Concow tribe call the acorns lō-ē’ (Konkow language).
