Champion and Notable Trees
Large trees are irreplaceable assets in our urban forest. They provide enormous economic and environmental benefits.
The State of Maryland has been measuring big trees since 1925, the oldest program in the nation. The point system used across the country was developed by Maryland’s first forester, Fred Besley. A tree receives one point for every inch of circumference as measured 4.5 feet above the ground, and one point for every foot of height, and 1/4 point for each foot of average canopy spread.
In Baltimore City, Tree Baltimore partner, the Baltimore City Forestry Board records official measurements. Explore our notable tree map or nominate a new champion.
