The Division of Forestry is cooperating with the American Forestry
Association in an attempt to find the biggest trees of each kind in the
United States and/or in Illinois. If you know of a tree that you think
might qualify, send the following information to the State Forester’s
office in Springfield: species, trunk circumference in inches (measured
4½ feet above the ground); total tree height in feet; and, average width
of crown in feet. If your candidate appears to be a winner, a state
forester will be sent to determine the exact measurements. If it is a
winner your name, the kind of tree and its dimension will be placed on
our list. You will receive a certificate stating that you have found a
“Big Tree Champion.”
