Many mammal and bird species feed off the berries, including juncos, American robins, cedar waxwings, band-tailed pigeons, varied thrushes, quail, mule deer, raccoons, ring-tailed cats, and bears. As the fruit are produced in great quantity and may persist on the tree into winter, their value as a food source is great. Mule deer will also eat the young shoots when the trees are regenerating after fire. The flowers also produce nectar which can be made into honey. Mature leaves are almost always ignored by browsing animals, but young leafy sprouts are eaten by ungulates and the dusky-footed woodrat. It is considered a high-importance winter forage species for many ungulates.
