Ann Arbor's Champion Tree program identifies and catalogs the largest tree of each species within the city. The program was created in 1995 to both, highlight and recognize these amazing trees, and to increase awareness of and appreciation for all the trees that help make Ann Arbor "Tree Town."
The 1995 Champion Tree list was recently reviewed and trees were verified, re-measured and photographed. The updated list can be found on the
Champion Tree Map; the map provides the species, size, location and the environmental, social and economic benefits of each tree.
The Slippery Elm Champion Tree, pictured above, is located at 2942 Sharon Drive and currently earns 253 Champion Tree Points. It has a circumference of 151 inches, height of 81 feet, and a crown spread of 84 feet. Over the course of a year, this tree provides $171 in energy savings, intercepts 8,637 gallons of stormwater, and sequesters 2,226 pounds of carbon dioxide. All of these amount to about $472 in overall total annual benefits.
How is a tree determined to be a champion?
Champion tree status is determined based on a point system calculated using the following formula:
Circumference (in.)+Height (ft.)+1/4 Crown Spread (ft.)= Total Points
The tree with the highest point total becomes the champion for that species.
