"How old is a 39 ” burr oak tree? In the case of the 48” bur oak, again, we know that a 39” specimen is about 254 years old. A 48” tree is about 23% larger than that, so we would calculate it to be 312 years old, and say the tree could be 300 years old!"Without a doubt. We had a giant one taken down on the corner of my lot last year. Sad day. Was easily over 100 years old, but we had no choice. A fungus had gotten into it, and the base was hollowing out and it was going to fall onto my neighbor's house.
My uncle wanted to log a woods we had and cut a very massive Burr Oak about 30 years ago and there is still a hole in the tree canopy where it was taken out and it was about 5 feet in diameter, if I remember correctly. He only got around $50 for it-what a waste.
