I see what you are doing. The circumference is divided by 3.1415 (Pi) to
obtain the diameter of the tree, which is then multiplied by the growth
factor to obtain an approximation of the age of the tree.

Your sugar maple would have an estimated age of 60" x 5 = 300 years in a
non-forested environment. There are to many factors that could affect the
growth rate in a forested situation.

The tree is 60 inches in diameter at the 5 foot level, and is in a
residential front yard in Nashville TN. There was a Silver Maple that
shaded it somewhat, but that went down a few years ago in a tornado. By
the chart used from
http://www.learner.org/jnorth/tm/leaf/HowOld.html

I figure if it was in a forest it would be 95 years old. How would I
figure age in a non forest area?

PS - Thanks for the great book recommendations - I'm about half way
through Forest Primeval and I'm seeing the woods I frequent in a totally
new light! (And I love my Textbook of Dendrology!)
