How do you measure a tree? The basis of the Tree Register is to assess trees in a holistic way. American Forests have been doing this for 77 years.

The points allocated to a tree are based on their formula which is:

Total points = trunk circumference (inches) + height (feet) + 1/4 average crown spread (feet)
