In order to get the complete table, make sure your printer settings are set to landscape print format.

All Native trees are listed first - cultivated trees follow.

Minimum tree dimensions are: 3 inches DBH and 13 feet tall. Identification of challengers must be confirmed. Index points = circumference (inches) + height (feet) + 1/4 average crown spread (feet). Co-champions are declared when there are two trees of the same species within 5 index points of each other.
