Classification and Tree Description

 Age
 Young                   Juvenile tree between 1 – 5 years

 Early-mature            Tree is still growing (6 years to 15 years)

 Semi-mature             Tree is still growing (over 15 years to 25 years, depending on the species)

 Mature                  Species has reached expected size

 Senescent               Over mature (tree has reached its useful life expectancy) and in decline

 Dead                    Tree is dead


 Appearance
 Excellent               Exceptional specimen. Crown full and balanced. Foliage is entire with good colour. Minimal or no pathogen
                         damage.

 Good                    Crown is full (can be unbalanced). Foliage is entire with good colour. Minimal or no pathogen damage.

 Fair                    Tree has < 30% deadwood. Canopy may be unbalanced. Foliage generally with good colour, however may
                         have some discolouration present. Minor pathogen damage present (typical for species in location).

 Poor                    Tree has >30% deadwood. Foliage may be discoloured or distorted and stress symptoms may be apparent
                         that could lead to decline of tree.

 Dead                    Tree is dead.


 Structure
 Excellent               Excellent branch attachment, no structural defects. Trunk sound. No damage to roots and good root
                         buttressing present.

 Good                    Good branch attachment and or no minor structural defects. Trunk sound or minor damage. No damage to
                         roots and or good buttressing.

 Fair                    Some minor structural defects and or minor damage to trunk. Bark may be missing & cavities could be
                         present. Minor damage to roots.

 Poor                    Major structural defects and or trunk damage and or girdling or damaged roots that are problematic.

 D.B.H.                  Diameter at Breast Height, measured at between 1.4 and 1.9m above the ground.


 Priority Classification
 Imminent Failure        This tree is a health and safety risk and could fail at any time. It is recommended that immediate action be
                         taken to eliminate the associated risk to people and infrastructure. This tree will fail in an extreme weather
                         event such as high winds or thunder storms.

 High                    This tree is likely to fail within a 6 month period, if exposed to extreme weather events such as high winds
                         or thunder storms.

 Medium                  This tree may fail within a 6 to 12 month period. If exposed to extreme weather events such as high winds
                         or thunder storms this tree may fail.

 Low                     This tree is unlikely to fail in the next 12 months. Remedial action may be taken to such as pruning to
                         mitigate the risk to people or infrastructure.
