In the mid-1970s, Tennessee launched its champion tree program with the intention of identifying and cataloguing the largest native trees in East Tennessee. The program has expanded to accept trees from across the state. In collaboration with the Tennessee Division of Forestry, the Department of Forestry, Wildlife and Fisheries at the University of Tennessee actively administers the state champion tree program.
There are hundreds of champion trees that cover the state. View the most current list of the champions by species, or view the Champion Trees of the Month below.
Nominations for the 2022 season are now closed. If you’d like to be notified when the 2023 nominations open, please click here.

A champion tree candidate is awarded points based upon trunk circumference, crown spread, and total height. If the candidate tree is awarded a total point value that exceeds that of the current champion by five or more, or there is no current champion, that candidate assumes the title. If the largest trees of a species are under 100 total points, trees will be crowned Co-Champion Trees if they are within 3 total points of each other. If the largest trees of a species are over 100 points, they will be Co-Champions Trees if the differential between them is no more than 3% of the larger tree’s total points.
After the nomination period closes, a trained evaluator will contact you to measure your nomination the concurrent summer to conduct Champion Tree measurements.

Trunk Circumference: circumference is measured at 4.5 feet above the ground directly above the center of the trunk. If the tree bifurcates below 4.5 feet, than the largest of the two forks is measured. If bifurcation occurs at 4.5 feet, then circumference is taken at the narrowest place below the fork. Trunk circumference is measured in inches with a forestry DBH tape (Basic circumference measurement diagram was adapted from American Forest Workshop, University of Tennessee, 2016).
Tree Height:For the purpose of champion identification, tree height is considered to be the vertical distance from the base of the trunk to the topmost twig. To ensure accuracy of measurement, a laser range finder is used. Height is measured to the nearest foot (Tree height definition was adapted from American Forest Workshop, University of Tennessee, 2016).
Average Crown Spread: As trees grow asymmetrically, points awarded for crown spread are based upon the average of the tree’s widest and narrowest points. Average crown spread = (wide spread + narrow spread) / 2. Again, to ensure accuracy of measurement, a laser rangefinder is used (Crown spread diagram was adapted from American Forest Workshop, University of Tennessee, 2016).
How we tally the final score?
After measurements are completed, champion status is determined in the following manner:
- One (1) point for each inch in circumference
- One (1) point for each foot in height
- One-fourth (1/4) point for each foot in average crown spread
Total points = circumference in inches + height in feet + one fourth of the average crown spread in feet
