Age Range of Trees. Trees can live, in very rare cases, up to six thousand years, although reaching that age is highly unlikely. Trees are most likely to live to old age in old-growth forests. For example, a Douglas Fir may live anywhere from 400 to 600 years in optimal conditions. As a shorter example, the average cherry tree life expectancy is around 20 years.
