Property Vegetation Hazard / Risk Assessment / Appraisal. (21-08-2014)
Visual Tree Assessment — VTA. (21-08-2014)

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’.
