Many elm (Ulmus) trees of various kinds have attained great size or otherwise become particularly noteworthy; among these are the following.
Most of North America's notable elms are Ulmus americana, a fast-growing and long-lived species capable of attaining great size in a few centuries, especially when open-grown.
[1] American Forests, a non-profit conservation organization, uses the following formula to calculate a point score for each tree to permit comparisons with others:Trunk Circumference (in inches) + Height (in feet) + 1/4 Average Crown Spread (in feet) = Total Points[2]The list of United States state champion American elm trees below tabulates each of the above characteristics, as well as the total points awarded to each tree.
