Summary

1, Samuel Cowie Arborist/Horticulturist and Principal of Leaf & Limb Horticultural
Consultancy, have been engaged by Matrix. [have been engaged for the purpose of
investigating and reporting on options rejated to the retention or remoyal, and protection of
the existing irees located on ihe site being developed as The Essence of Peregian, and advise
on any relevant on-going tree management that is required between trees and proposed
development works, | inspected the site and trees on the 14” of April 2010 and the 7" of June
2010. The site inspection and this report were conducted as per SCRC’s DA conditions,
specifically conditions No 17, 18, and 49, The report also addressed issues with condition No
16. This forms the brief of the report.

 

   

Condition No 16

Given the extensive nature of the bulk earthworks agross the majority of the site. the overall
age/poor health and structure of the Melaleucas on the site, retention of any trees outside of
the building footprints isn’t possible for a long-term health and structural arboricultural
perspective.

 

Condition No 17

The requirement to install sheet piling outside of the building located in the south-castern
corner of the site will impact heavily on Trees No 1, 2,3 and 4. Tree No | has a poor
retention value due to the basal structural defect and poor useful life expectancy, where as
Trees No 2, 3 and 4 will be severely impacted by the sheet piling. Combined with their
overall small stature, therefore lacking significance when compared to larger trees, removal
and replacement of all 4 trees is the best option and will increase the future teeescape of the
nature strip and site.

‘Tree No 5 is neither in good health or structure, therefore removal and replacement with a
supertor specimen at the landscape phase is the best option.

Tree No 6 has a short useful life expectancy due to the loss of a major first order branch,
including a major future structural issue, therefore the retention value is low and removal is
recommended.

 

Trees No 7, 8 and 9 are also poor specimens for retention, This is due to their advanced age
and prevalence of the decay fungus Phellinus throughout their branch structure. The client
requests and prefers the retention of these trees, and given the driveway footprint, retention
maybe possible under supervision of a qualified sit arborist and as per AS4970-2009.

Condition No 49

Assessment of the KIIMP by James Warren and Associates found no trees specified for
relention due to Koala activities, therefore the requirements of this condition aren't
applicable.

Tree Prviection (Wesiern Reserve)

Although not addressed under the conditions of DA consent, the trees and vegetation located
on the western side of the gabion wall are retainable (no obvious impacts or future targets in
their vicinity}, Protection of the vegetation and trees maybe done by installation of
appropriate fencing and signage with the assumed erosion contro! measures placed on the
western side of the gabion wall during construction,

Tree Protection prior, during and after development works
‘The tree management and protection plan recommended in this report (6.3) should be
implemented to preserve and relain trees numbered 7, 8 and 9 if requested by the client.
