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.
For example, acorn production in a northern red oak generally peaks when the tree diameter at breast height (dbh) (4.5 feet above the ground) reaches 20 inches and then gradually declines as the tree grows larger (Figure 9). In contrast, acorn production in white oaks peaks at about 26 inches dbh. Table 2.
