Question:
We have three very large Tulip tress in our yard in an Atlanta, GA suburb. The trunk diameters range from 4' down to 3'. There is a larger dead one around 5.5' Our neighbor's kids love the large trunk size and shear height of these wonderful trees. We esitmate the tallest at around 60'. I was wondering if there was a table or estimation guide to their age in relation the the trunk diameter and or height.

Replies:
Here's a page with a formula for estimation of age based on diameter (in inches).

Liriodendron tulipifera Tulip Poplar 2.5 X d.b.h. (diameter at breast height, or ca. 4.5 feet above ground) (in inches)
