A champion tree is the largest of its species. The trees are measured using American Forest points (AF points) using the trunk circumference, its height, and the width of the crown of the tree. A tree must be measured every decade in order to maintain its champion status. Trees that have totals within 5 points of each other are co-champions.
Trunk Circumference (inches) + Height (feet) + ¼ Average Crown Spread (feet) = Total Points.
