What Is a Champion Tree?

A Champion Tree is the largest known tree of a given species in a particular geographic area. The champion English elm, or "Goshen Elm," in Gaithersburg is a Champion Tree. The Montgomery County Forest Conservancy District Board has kept a list of Champion Trees in the County since 1989. The Board publishes its Champion Tree Register every other year.

Champion Tree Measurement Formula

The official Champion Tree Measurement Formula was developed by Fred Besley, Maryland's first State Forester. With some modifications, it was later adopted nationwide. Mr. Besley began keeping records of "notable trees" in Maryland in 1925. The formula is

Circumference (in inches) + height (in feet) + 1/4 of the average crown spread in feet = total points

The tree's circumference is usually measured 4.5 feet from the ground at the base of the trunk unless the tree forks below 4.5 feet. The crown spread is the average of two trunk-to-branch tip measurements taken at a right angle (90 degrees).
