In my view it is virtually impossible to estimate a bur oak's age by its size, unless you know its whole history. Trees of identical diameters growing relatively close to one another can be 100 years (or more) different in age.
here is some peer reviewed evidence supporting this idea: http://academic.udayton.edu/RyanMcEwan/Pub/2008,McEwan_and_McCarthy,JBI.pdf This is true, in fact, for many species... I was sampling chinkapin oak with Neil Pederson last fall and we found one tree that was 400 years old, and on the same site, not far away at all, a tree that was a bit LARGER in diameter (and crown) that was 150 years old (250 years younger). ryan On Tue, Aug 4, 2009 at 9:26 AM, Lee Frelich <[email protected]> wrote: > > Mike: > > My guess is about 150-175 years. > > Lee > > Mike Kowalski wrote: > > ENTS, > > > > Here are some photos of a beautiful bur oak not far from where I live. > > They are from both last December and April of this year. > > > > The tree has a CBH of 414 cm (163 inch).
