Oak trees are among the trees that have the longest life spans as they can live for more than 1000 years.
The average life span of suburban oak trees can be a lot less due to mechanical damage, poor pruning techniques, pollution and a host of other reasons.
It is fair to say they are a very long lived tree though.

Do oak trees die of old age?

At maturity, an oak tree can be 45 meters tall and may reach a width of 90 meters. For 700 years, the number of acorns that they produce and the growth rate reduces. Some parts of oak trees start to die when they attain 1000 years. An oak tree can produce up to 10 million acorns during its lifespan, and some of the acorns germinate and become a new generation of oak trees.
