Boom and bust cycles of acorn production do have an evolutionary benefit for oak trees through âpredator satiation.â The idea goes like this: in a mast year, predators (chipmunks, squirrels, turkeys, blue jays, deer, bear, etc.) canât eat all the acorns, leaving some nuts for growing into future oak trees.
Oak trees grow from acorns that drop from the trees in early fall. Oak trees produce both male and female flowers on the tips of their uppermost branches, which are relatively unnoticed. Pollen from the male flower fertilizes the female ovary, which develops into an acorn. The petals and sepals of the ovary fuse to form the acorn's top, or cap. The acorn falls off the tree in late summer or early fall, and under the right conditions will germinate and grow into a new oak seedling.
