 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.
