1.3. COMMENTS / SUMMARY OF OBSERVATIONS
1.3.1. After conducting an on-site “Property Hazard / Risk Assessment”, “Visual Tree Assessment”
(V.T.A.) and “Appraisal”, seven “Subject Trees” in question were identified with concerns; the
“Issues” and main “Concerns” with these “Subject Trees” at the time of the Assessments
and Appraisal identifies and places these “Subject Trees” into a High “Hazard / Risk” rating;
these influences and ratings are set out below:
1.3.2. The Assessments, Appraisal and Report were instigated in regards to Steven Cooksey,
RACV Noosa Resort Maintenance Manager’s duty of care of this property in question for all
that work, visit / holidays and or enters this property.
His concerns and issues are inflicted on a daily basis with all “Subject Trees” located on the
infringement of the natural bush land that surrounds the RACV Noosa Resort, extending /
approaching towards and or over resort dwellings, pathways, recreation areas etc; especially
when extreme weather events / conditions are approaching.
1.3.3. This is due to the “Species”, “Age” and “Size”, “Structural stability / Integrity”, “Tree
health” and most importantly the “Location / Position” of these “Subject Trees”.
1.3.4. Six of the “Subject Trees” are Eucalyptus robusta – Swamp Mahogany, this is an extremely
tall / large hardwood species that can reach up to 35 meters.
1.3.5. All “Subject Trees” are exhibiting hazardous asymmetric phototropic influences and or growth
form due to the construction and development of this property, a large section / area within
the property was cleared for construction / development to accommodate the resort dwellings,
including associated attachments and infrastructure, above and below ground level.
Note: Phototropism - Growth towards light source and stimulant.
1.3.6. All “Subject Trees” have had lower limb / stem failures and or have had lower limbs / stems
removed which are displaying low “Live Crown Ratio” (LCR); due to developing within a
closed forest environment, before being exposed and now all on the infringement of the
natural bush land due to the clearing of existing natural vegetation and construction /
development stage of the RACV Noosa Resort.
Note: Trees with low LCR (Low Crown Ratio) are acknowledged and or recognized to be
typically weak and lack vigor.
Note: An extra problem these trees have to contend with is as a result of over pruning
and or the loss of their lower canopy, winds hitting these trees are to now impact more
greatly on the crown as the tree has lost the ability to dissipate force via resistance
distribution of the lower branches.
1.3.7. NOTE: Combined, Phototropic growth form, Low Crown Ratio (LCR) and excessive end
crown weight, including poor tree health with the exposure to excessive wind forces now are
compromising the structural integrity and stability of these trees in question.
1.3.8. All “Subject Trees” are displaying excessive amounts of hazardous epicormic growth
throughout their crowns.
Note: Epicormic shoots unlike normal branches that develop in a socket of overlapping
wood tissues are in fact growth anchored only in the outermost layers of the parent
branches.
Epicormic shoots grow quickly, up to 6 meters in one year. Unfortunately, these shoots
are prone to die back and or fail / break off, especially during stormy windy weather.

1.4. CONCLUSIONS / RECOMMENDATION
1.4.1. NOTE: This “Property Vegetation Hazard / Risk Assessment”, “Visual Tree Assessment”
(V.T.A.), and “Arboricultural Report” was based off and compiled with “On-Site Consultations”,
“On-Site Assessments and Appraisals” also referring to “Acknowledged References”.
1.4.2. With these “Conclusions” founded in “Comments and Observations” on pages 5 to 9,
“Photographs” in Appendix 2.1. on pages 12 to 19, “I.S.A. Tree Hazard Evaluation Forms” in
Appendix 2.4 on pages 22 to 35, also referring to the “Acknowledged References” in
Appendix 2.5 on page 36, of the seven subject tree’s “SPECIES SUITABILITY”, “AGE CLASS
and foreseeable SIZE”, “POSITION / LOCATION”, “STRUCTURAL STABILITY /
INTEGRITY”, including “TREE HEALTH” of these species, and the REPERCUSSIONS if
these trees are allowed to remain.
1.4.3. Taking into consideration that tree health, tree growth habit and hazard are not equivalent;
trees that are apparently healthy may possess significant structural defects. In such cases,
trees normally considered healthy and or vigorous may fail. While tree health and structural
stability are related, they are not equivalent.
1.4.4. My “Recommendations”; given all considerations to all the issues and concerns associated
with the seven “Subject Trees”, in question only, having an unacceptable risk to safety / harm
in this high usage / profile public, residential and commercial environment, including
foreseeable extensive damage to surrounding dwellings, and infrastructure, and as long term
management is unsustainable; and at this stage no remedial work can be used to reduce the
risk of total tree failure and or stem failure, as total tree failure and or stem failure in these
species is “UNPREDICTABLE” and not an annual event, adding the unpredictability with total
tree failure and or stem failure in the future, and will only “INCREASE” as these “Subject
Trees” become older and taller (Over mature / Senescent), including increasing annual
extreme weather events and or the unpredictable acknowledged phenomenon such as
“Summer branch drop” or “Sudden limb drop”, which the Arboriculture industry discusses and
debates still today why this phenomenon occurs without any signs, warning and or reasoning.
1.4.5. All seven “Subject Trees” in question should be removed out of this high usage / profile
public, residential and commercial environment, and suitable endemic vegetation species
should be reinstated.

2.6. DISCLOUSURE STATEMENT
2.6.1. The information pertaining to the condition of the tree(s) and / or vegetation in question in this
report covers only the tree(s) and / or vegetation that was examined and reflects the condition
of the tree(s) and / or vegetation at the time of the inspection only, the information was
gathered by a “Visual Tree Assessment (V.T.A.) / Evaluation” from ground level only; No
aerial inspection or below ground surface inspection, dissection of plant parts, formal
identification of pest and diseases or scientific testing of any kind was carried out; also the
information gathered in this report is and has been believed to come from a reliable source.
As an Arborist, I am a tree specialist and use my knowledge, training and experience to
examine trees and / or vegetation, recommend measures to enhance their beauty and health,
and to attempt to reduce the risk of living near trees and / or vegetation. As a client, you may
disregard these recommendations, or seek additional advice.
An Arborist cannot detect every condition that could possibly lead to a tree or limb failure.
Trees are living organisms that may fail in many ways we do not fully understand. Conditions
are often hidden within the tree and below the ground. As an Arborist we cannot guarantee
that a tree will be healthy or safe under any circumstances, or a specified period of time.
Sometimes trees may appear “Healthy”, but may be structurally unsound. Likewise remedial
treatment, like any medicine, cannot be guaranteed.
Furthermore, certain trees are borderline cases as to whether they should remain or be
removed. Also conditions change, and a tree may need further monitoring in the future to
determine its health and structure. Of course the only really safe option is removal.
Trees and / or vegetation can be managed, but they cannot be controlled, and to live near a
tree(s) and / or vegetation is to accept some degree of risk. The only way to eliminate all risk
is to remove all trees and / or vegetation.
NOTE: Unless otherwise stated this report cannot be used within a court of law and or any
legal situation without prior consent of Regional Arboricultural Services.
