Points Calculation : National Register of Big Trees



Points Calculation

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] + Average Crown Spread [feet]

SCIENTIFIC NAME COMMON NAME CIRCUMF. (inches) HEIGHT (feet) CROWN (feet) POINTS
Araucaria heterophylla Norfolk Island Pine 166 136 34 310
    4.22m 42m 11m  
Eucalyptus grandis Flooded Gum 362 252 150 652
    9.20m 77m 46m  
Ficus macrophylla Moreton Bay Fig 393 88 114 510
    10.00m 27m 35m  

 

The Register records both metric and imperial measure.

The support of American Forests in the establishment of this Register has been invaluable.

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 Register.
  • 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.
