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.
Like other nut bearing trees, oaks produce a large amount of acorns; unlike other nut-bearing trees (pecan, walnut and hazelnut) the seed nuts cannot be consumed by humans or most animals because of the tannin in the seed. A huge quantity of acorns must be produced for an oak to propagate itself.
