Under ideal conditions, oak trees live an average of 150 years, with short-lived varieties lasting 50 to 60 years and long-lived varieties living more than 150 years.
During stressful periods, oak trees will drop acorns to redirect its energy from producing seeds. Oak trees (Quercus spp.) take decades to mature. Depending on their species, the trees are 20 to 30 years old when they produce their first acorns. Even then, acorn production is not consistent from year to year.
