Arborist Brief

5. Conclusion:
Tree No. 1 requires extensive pruning work to remove all large dead sections within the canopy.
Various branch structures require end weight reduction including the co-dominant stem which
over hangs the driveway and service wire to 25 Dwyer Street. This stem is structurally
compromised and will require removal back beyond the shear plane crack to the stem bark ridge.
End weight reduction to reduce the load force on this fault is not practicable due to the formation
of the second order branch structures.
A considerable amount of pruning work is required for this tree. Branch end weight reduction
crown maintenance and the removal of the co-dominant stem will exceed the percentage of
annual pruning allowable within a growth season. It is of my professional opinion that this tree has
reached the final stages of its useful life expectancy within its urban setting.
Evidently tree No. 2 is presenting signs of poor vigour with a rapid decline in health and structure
This tree should be removed for safety reasons within 2 months.
Tree No. 3 should be retained and will require protection throughout the stages of the proposed
works. Refer to AS 4970, Tree Protection on Development Sites for tree protection methodologies
throughout the stages of construction.



6. Recommendations:
        •   Utilise sensitive earthworks methods to avoid damage to vegetation whilst removing
            the existing concrete driveway.

        •   Employ a qualified arborist team AQF 3 or equivalent to carry out the removal of the
            vegetation on the northern side of the existing driveway.

        •   Provide Supplementary plantings to compensate for vegetation loss.

        •   Refer to the development guidelines AS 4970 Protection of trees on development
            sites.

        •   Refer to the guidelines of Noosa Shire Councils tree management principles.

        •   Employ a consulting arborist to oversee future excavation works around tree No. 3.

        •   Consider selecting species which are native and salt tolerant.
