1.3. COMMENTS / SUMMARY OF OBSERVATIONS

1.3.1. After conducting an on-site “Property Hazard / Risk Assessment / Appraisal” and “Visual Tree
Assessment (V.T.A.) / Evaluation”, on the eight “Subject Trees” in question only; | found the
“Issues” and main “Concerns” with these “Subject Trees’ in this high usage urban gated
residential and public community / environment at the time of the Assessments / 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 the “BAYVIEW
WOODS’ - Body Corporate duty of care to this property; the years of mental anguish for all
that enters and or reside within this residential community. There worries, concerns and
issues that are inflicted on a daily basis, especially when extreme weather conditions are
approaching.

This is due to the “Species”, “Age”, “Size”, “Structural stability / Integrity”, and most
importantly the “Location / Position” of these “Subject Trees” within this property.

4.3.3. Furthermore, as | have been informed that over time all that reside here have at one time or
another witness and or have found small to large dead and live limb / stem failures on the
ground, even entire tree failures, weather it was calm, during and or after a extreme weather
event; one event to mention that occurred on this property, with almost a catastrophic
outcome when a mature Lophostemon totally failed, falling across the property’s main access
driveway, with the top of the crown reaching less than a meter short of lot 3 residential
dwelling, with the crown exploding hurling debris in all directions.

1.3.4. The “Subject Trees” on this property have developed within a close forest situation; with the

nee development of this property;'a large section / area within the property was-cleared for ~:
construction to accommodate the residential dwellings, including associated attachments and
infrastructure, above and below ground level.

1.3.5. Now the “Subject Trees” are all located on the infringement of the natural bush land / clearing
and exhibiting hazardous asymmetric phototropic influences and or form.

e Note: Phototropism - Growth towards light source and stimulant.

1.3.6. The “Subject Trees” all display low “Live Crown Ratio” (LCR), due to developing within a close
forest situation, combined with the exposure to excessive wind forces now are compromising
the structural integrity and stability of these trees, due to these trees not structurally
developing as trees in an open forest situation.

All “Subject Trees” have had extensive lower limb / stem failures and or have had lower limbs
/ stems removed.

e Note: Trees with low LCR are acknowledged to be typically weak and lack vigor.

e 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. | believe that in this closed forest situation, trees number one, three, six, seven and eight
have sustained “Apical Meristematic Tissue” damage, either by “Abiotic” (Non-Living) and or
“Biotic” (Living) influences in their early growth cycle, and has then developed “Co-dominant
Stems / Leaders” (Bifurcated Stems) and or “Multiple Dominant Stems / Leaders” all arising at
one point on a single root crown.

Tree number two has developed a Structural defect leader exhibiting “Included Bark’, located
1.2 meters up from ground level.

e Note: “Co-dominant Stems” (Bifurcated Stems) and “Multiple Dominant Stems” arising at
one point on a single stem represents an influential structural defect within the tree
system, and sets the scene for fracture.

1.4. CONCLUSIONS / RECOMMENDATION

1.4.1. NOTE: This “Property Vegetation Hazard / Risk Assessment / Appraisal”, “Visual Tree
Assessment” (V.T.A.), and “Arboricultural Report” was based off and compiled with “On-Site
Consultations’, “On-Site Assessments / Appraisal” and “Acknowledged References”.

1.4.2. With these “Conclusions” founded in “Comments and Observations” on pages 5 to 8 and
the “Acknowledged References’ in “Appendix 2.4” on page 21, also referring to “Photographs”
in “Appendix 2.1. on pages 11 to 18 of the eight Subject Tree's “Species Suitability’, “Age
Class and Size”, “POSITION / LOCATION”, “STRUCTURAL STABILITY / INTEGRITY’,
“History” and the repercussions if these trees are allowed to remain.

1.4.3. Taking into consideration that tree health 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 these eight “Subject Trees” in question only, having an unacceptable risk to safety,
including foreseeable extensive damage (attached and or associated with this property), 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 stem failure in these two 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 the Lophostemons and

me older and taller (Over mature / Senescent), plus extreme weather events or

‘able 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, these eight “Subject Trees”
in question only should be removed, out of this high usage urban gated residential and public
community / environment, and suitable endemic vegetation species should be reinstated.

  

1.4.5. Note: A list of suitable endemic species has been compiled and submitted to the “BAYVIEW
WOODS" Body Corporate for the replacernent vegetation; referring to the “Noosa Plan -
Noosa Landscape Guidelines’.

* Asan Arborist, | am a tree specialist and use my knowledge, training and experience to
examine trees, recommend measures to enhance their beauty and health, and to attempt
to reduce the risk of living near trees. As a client, you may disregard these
recommendations, or seek additional advice.

e 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 can be managed, but they cannot be controlled, and to live near a tree is to accept
some degree of risk. The only way to eliminate all risk is to remove all trees.
