The northern red oak and the white oak tree provide food for various wildlife, including animals and birds. Oak trees specifically provide food for diverse animals, including deer, blue jays, turkeys, rats, raccoons, squirrels, and bears. Other birds, such as barn owls and wood ducks, build their nests in the crevices of mature trees.

Insects eat leaves, bark, wood, acorns, and twigs. For example, bees build beehives in the hollows of some oak trees. Some animals that consume acorns store them for later use, and in doing so, they create new oak forests by replanting any acorns that have been forgotten.

Their first fruit can usually be expected at 25 years of age, although most do not produce an abundance of acorns until they are 50 years old. However, trees as young as ten years old may produce fruit in favorable conditions. The USDA reports that acorns are viable for up to three years when the conditions are optimum for the tree's growth.  

Most of the time, the northern red oak tree produces acorns either single or in groups of two to five. As they mature, the fruits turn reddish-brown and ripen between September and October, depending on the location and the climate.
