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.
Huge oaks can live to be 200 years old. Acorns are the fruit of oak trees. Every fall these often massive, stately trees produce a rain of acorns that are quickly eaten, buried, or stored by a wide variety of animals. Acorn size varies from one-fourth inch to over 2 or 3 inches, depending on the species.
