Guide Massachusetts Big Tree Registry

The Department of Conservation and Recreation Forest Health Program formally recognizes the largest known tree of each species growing in the state with the Massachusetts Big Tree Registry.

Big Tree and Champion Tree Registry

DCR's Bureau of Forest Fire Control and Forestry maintains a database of the current Big Trees.  Using a point system, a trained Forester will work with you to determine if your Big Tree is a Champion Tree.  The circumference is taken as well as the height and average spread of the crown to come up with the big tree points.  Within each species, the tree with the highest number of big tree points is considered the champion.
