A PPENDIX 1: D EFINITION OF T ERMS
 Age Class (AC):
 Y           Young: Early stage of growth, immature size
 EM          Early Mature: Fast-growing well-established tree which has not yet reached mature size
 M           Mature: The tree reached its mature size, and exhibits slowing growth rates with early stages of naturally forming
             dead or dysfunctional wood.
 AA          Advanced-Age: The tree has reached mature size and is unlike to increase significantly in height or mass.
             Retrenchment of the upper crown with increased vegetative vitality in the lower crown, increased fungal activity
             and wood decay, and increased colonisation by flora and fauna.
 V:          Veteran: Tree with advanced retrenchment, reduced crown size and annual increment growth, extensive hollowing,
             crown collapse, low vigour, advanced heartwood decay, advanced colonisation by fauna and flora.
 S:          Senescence: the natural aging of plant tissues and organs, leading to irreversible decline in physiological functions.
 Health (H):
 GH          Good: Tree with no defects or disorders which are notable. Full canopy with good colour foliage. Minimal pathogen
             damage.
 FH          Fair: Tree with minor defects or disorders which are notable. Some dead wood within what can be an unbalanced
             canopy, foliage generally with good colour although some discolouration may be present typical of species in
             location. Minor pathogen damage.
 PH          Poor: Tree with major defects or disorders which are notable. The tree has considerable deadwood present and
             discoloured or distorted leaves indicating a further decline of the tree. Detrimental pathogen damage.
 D           Dead or dysfunctional moribund tree.
 Structure (St):
 GS          Good: Tree with good unions and no branch defects. Sound trunk with no / minor defects. Good buttress and root
             structure.
 FS          Fair: Tree with minor defects or disorders which are notable. Small areas of bark missing. Small cavities or minor
             unfavourable branch unions may be present. Minor damage to roots.
 PS          Poor: Tree with major defects, large hollows, weak unions and/or problematic damaged roots.
 HS          Hazardous: This implies a tree with a major defect that may fail at any time
 Abbreviations:
 Ht          Height
 CS          Crown Spread
 DBH         Diameter at Breast Height - The approximate diameter of the trunk measured visually in millimetres or meters at a
             height of 1.4m.
 TPZ         The Tree Protection Zone, as per AS 4970-2009 Protection of trees on development sites, is the principal means
             of protecting trees on a development site. The TPZ is a combination of the root and crown area requiring protection
             to be isolated from construction disturbance so that the tree can remain in a viable condition. The TPZ incorporates
             the Structural Root Zone (SRZ).
             The radius of the TPZ = DBH x 12
             A TPZ should not be less than 2m or greater than 15m (unless crown protection is required).
 SRZ         The Structural Root Zone, as per AS 4970-2009 Protection of trees on development sites, is a mathematical
             calculation of the surface area of protection required to maintain a tree’s stability – a larger area is required to
             maintain a tree in viable health. It is only necessary to calculate the SRZ when a major encroachment into a TPZ
             is proposed.
 Recommended Works:
 Aerial Inspection:       Assessment is to be carried out either by Consult Arborist or a Qualified Arborist contractor to assess
                          defects within the canopy and report findings.
 Canopy                   A combination of removing dead wood and selective pruning to benefit the tree’s future health and
 management:              canopy structure. The end-weight reduction of longer lateral branches, with the creation of future
                          growth points to sustain canopy growth and assist with natural canopy retrenchment.
 Deadwood and detail Remove deadwood (>40mm in diameter and/or 1m in length), and dysfunctional, damaged, and weak
                          branches from the tree’s canopy.
 End-weight               Trimming of the concentration of excessive wood and foliage weight towards the extremity of the
 reduction:               branch to lessen the overall load and branch failure potential.
 Mulch:                   The application of a layer of woodchip/forest mulch approximately 50-75 mm thick to the canopy drip
                          line where possible, leaving a small well around the base of the tree trunk.
 Proactive removal        To prevent future anticipated issues, remove the tree and replant with a more suitable species for the
                          location.
 Prune away from Prune branches to reduce the encroachment and weight of the branches growing towards the adjacent
 adjacent dwelling        dwelling/building.
 Reduce and retain        Reduce the tree to a safe height and size to limit hazards while retaining the remainder for habitat.
 Reinspect                A repeat assessment is recommended to be carried out 12 months from the date of this assessment
                          or after any major weather event.
 Selective pruning        Prune selective / identified branches to reduce end weight/length
 Soil/Plant Care          Apply organic compost around the base of each tree 20-30mm thick, leaving a small well around the
                          base of the tree trunk. Additional seaweed-based plant food/soil conditioners applied as per the
                          manufacturers’ guidelines and will help to improve soil biology and maintain the tree’s health.
 Stump grind              Remove the stump by grinding to approximately 100mm below the surrounding ground level when
                          located within mown grass or damaging infrastructure.
