Ryan Here in SE Pa where Bur oak is introduced, we have several large examples that 30 years ago people thought were over three hundred years old. http://www.pabigtrees.com/trees/images/trees%20by%20county/delaware/pictures/delco%2025%20collen%20brook%20bur%20oak%2008%20small.jpg
What I discovered was Bur Oak was not introduced/identified until 1812 (Dirr). So the trees in this part of the state typically date to the houses they are planted near. Often times the houses are older, but there was an addition put on the house in the early 1800's, and the tree was most likely planted then. We have a few here that are 17-21' cbh, but all of them are planted near old homes. Another Red oak that grew here was also believed to be 300 years old due to its size (over 20' cbh), but when it came down, a cookie from 37' up yielded only 151 rings. Estimated age of the 300 year old tree came down to 200 at that point. People do not like to hear that their tree is not ancient like they believed. They get very annoyed.
