Average Lifespan
Oak trees have a fairly slow growth rate. Most species of oak grow only 1 to 2 feet annually and may take years to become a mature oak tree.
The lifespan of an oak tree also largely depends on its species. While a few oak varieties live for 70 years or less, others can stay strong for more than 100 years. Most oak trees can survive for anywhere between 100 to 300 years. A few rare specimens, like the Angel Oak Tree in South Carolina, have been alive for hundreds of years.
Other than species, the lifespan of an oak tree is also affected by pests and diseases, environmental conditions, commercial development, etc.

FAQs
Q. How can you determine the age of a white oak tree?
A. Knowing how long do white oak trees live, it was difficult to asses its age. But thankfully, today it is quite possible to determine the age of a white oak without using the invasive method of core sampling.
Studies conducted by the U.S. Forest Service suggest that there is a clear correlation between the age of an oak tree and its breadth. To calculate the age of the tree, you can use this formula developed by the International Society of Arboriculture. All you need to use this method are a few simple methods.
Method:
- Using a measuring tape, measure the circumference of the tree’s trunk. While wrapping the tape around the trunk, make sure that it is about 54 inches above the ground.
- The next step is to calculate the diameter. Now use the formula circumference (in inches)/ pi (approx. at 3.14). For example, if the circumference of the tree trunk is 320 inches, then its diameter would be 320 divided by pi.
- Now multiply the diameter of the tree with its growth factor. The growth factor of a white oak tree is 5.
- This method will give you the approximate age of the white oak tree.
Q. How old is the oldest white oak?
