POINTS CALCULATION
The POINTS allocated to a tree will be based on the formula used by American Forests and it is:
Total POINTS = Trunk Circumference [inches] + Height [feet] + ¼ Average Crown Spread [feet]
For example:

Making the Australian tree Points directly comparable to the U.S.A. is important for these reasons:
- Australians can view the American Forests Register of Big Trees and gain immediate, and much enjoyment, in comparing their Champions with ours, and vice versa for North American tree enthusiasts viewing our NRBT.
- It will also make the Register interesting and relevant for visiting U.S.A. tree enthusiasts, and could encourage a significant number of visitors to this country who might not normally do so.
- For Australian tree enthusiasts visiting the USA, the reciprocal benefits apply.
The Register will record both metric and imperial measure.
