Key Guide

Age:

Infancy: Young tree, healthy, growth then enhanced by mycorrhiza root associates.

Juvenile: Continued to fast growth net cease in annual increment, low volume of dysfunctional tissue.

Semi- Mature: Growth to peak, deadwood formation, maximum pollination and seed capacity, some natural limb loss, increase of dysfunctional tissue, accelerated fungal colonisation and activity.

Mature: Retrenchment of growth, reduction in net annual increment contraction of live crown, increased vegetative vitality in lower crown, increased fungal activity and wood decay, increase colonisation by flora and deadwood.

Over-Mature: Advanced retrenchment, decline in crown size, and annual increment, extensive hollowing, crown collapse, decline in vitality, advanced heartwood decay, and hollowing, advanced fauna and flora.

Senescent: Terminal decline, tree death, continual in fungal activity, nutrient recycling.

Tree significance:

Highly significant: Rare/Endangered species or remnant to the area. Protected vegetation under a Local Law. High aesthetic value - tree has high significance in size / colour and shade.

Significant: Healthy and sound tree(s) which play a significant functional role to the local community and/or contributes to the over all landscape feature. Aesthetic - tree has a minor significance to size / colour and shade. Forms part of a recognised landscape theme.

Desirable: Well represented in the local area. Healthy sound tree that contributes to the landscape.

Un-desirable: Common and/or weed species. Diseased or declining tree. Undesirable species (weedy species).
Does not contribute to the overall landscape theme. Presents additional conflict with the infrastructure or safety that cannot be resolved through Arboricultural treatment.

Tree Health:

Excellent: Exceptional specimen, crown full and balanced, foliage entire with good colour, minimal or no pathogens damage and ideally suited to site.

Good: Crown full, can be unbalanced, foliage entire with good colour, minimal or no pathogen damage.

Fair: Tree has <30% deadwood, canopy can be unbalanced, foliage generally with good colour, some discolouration may be present, minor pathogens damage present, typical of species in location.

Poor: Tree has >30% deadwood, discoloured or distorted leaves and/or stress symptom that could lead to decline of tree.

Dead: Tree is dead/dysfunctional.

Tree Structure:

Excellent: Excellent branch attachment, no structural defects. Trunk sound. No damage to roots and good root buttressing. Good trunk and scaffold branch taper. No branch over extension.

Good: Good branch attachment and/or no minor structural defects. Trunk sound or minor damages. No damage to root and/or good buttressing present.

Fair: Some minor structural defects and/or minor damage to trunk. Bark missing. Cavities could be present. Minor damage to roots.

Poor: Major structural defects and/or trunk damage and/or girdling or damages roots that aremproblematic.

Hazardous: Tree poses immediate hazard potential.

Risk Assessment

Usage/target is the estimation of the occupancy and target potential within the fall zone of the subject tree.


Constant-use: A. Permanent structures, playground, car parks, pathways, formal lawn areas that are occupied daily and are being used 80%-100% of the time.
B. Freeways and major road corridors - Bus/Ferry/Rail terminals, traffic, pedestrian and road signals and signage, medical and emergency facilities.


Frequent-use: A. Permanent structures, playground, car parks, path ways, formal lawn areas that are occupied for a couple of hours of a day.

B. interconnecting road corridors and congested intersections - Bus/Ferry/Rail terminals, traffic, pedestrian and road signals and signage, schools and shopping centres and/or car parking adjacent to frequent-use public areas.


Intermittent-use: A. Permanent structures, playground, car parks, path ways, formal lawn areas that are occupied for a couple of hours a week.

B. Residential road corridors and congested intersections - Bus/Ferry/Rail terminals, traffic, pedestrian and road signals and signage, and/or car parking adjacent to intermittent - use public areas.


Occasional-use: Peripheral areas with with occasion use or access with dispersed recreation. Permanent structures, playgrounds, car parks and bush pathways, that are occupied a couple of times a month.


Low-use: Peripheral areas with low occupancy. No permanent structures and/or definitive bush pathways, visited a couple of times a year.


Likelihood of Failure:

Failure certain: The tree has significant structural damage, unsupported active split trunk(s), unsupported fractured/hanging branches, and dead branches/trunks and therefore failure is very likely to occur in most circumstances.

Failure likely: The tree indicates signs of excessive lateral branch weight, decay threshold has been compromised, root damage, supporting heavily embedded included bark, supporting fractured branches, major declining branches/trunks and therefore failure is likely to occur in most circumstances.

Failure possible: Mature to aged tree in declining condition, structure concerns, decay apparent, history of branch shedding, and therefore failure may occur at some time.

Failure unlikely: Tree appears healthy, but has a potential to develop minor deadwood and therefore failure is unlikely to occur at some time.

No detectable threats: Tree appears healthy, no apparent signs of disease or damage, or is not of a size or condition to pose a threat, and therefore failure is very unlikely to occur except in exceptional circumstances

Consequence of Failure:

Catastrophic: Death or major financial/property loss.

Major: Extensive injuries or major financial/property loss.

Moderate: Medical treatment required or high financial/property loss.

Minor: First Aid treatment or medium financial/property loss.

Insignificant: No injuries or low financial/property loss.

Risk assessment regarding Likelihood in combination with Consequence delivers an overall risk rating consistent with Standards Australia Risk Management AS/NZS 4360: 2004.
