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 don't start blooming and producing acorns until they are around 20 years of age, according to the University of Tennessee Extension Service. As the tree continues to grow, they start producing even more flowers and acorns until they are about 80 years old. At that time, acorn production begins to diminish. Oak trees produce the most flowers and acorns between the ages of 50 and 80.
