State Champion Trees
The Haverford College Arboretum currently boasts nine State Champions, eight of which may be found in or near the Ryan Pinetum.
Champion trees are determined by a point system based on three measurements. One point is given for each inch of the tree’s circumference measured at a height of 41/2 feet, one point is given for each foot of the tree’s height, and a quarter-point is given for each foot of the crown spread. The largest known measured specimen of its genus and species becomes State Champion.
