1        Introduction

1.1     I, Samuel Cowie Arborist/Horticulturist and Principal of Leaf & Limb
        Horticultural Consultancy, have been engaged by Matrix. I have been
        engaged for the purpose of investigating and reporting on options related to
        the retention or removal, and protection of the existing trees located on the 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.

         I inspected the site and trees on the 14th of April 2010 and the 7th 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.



2        Methodology

2.1      Identification of plant material was conducted using Barwick (2004), Rowell
         (1983) and Haslam (2004). All references to pruning are taken from AS 4373-
         2007, Pruning of Amenity Trees. Assessment of the trees was conducted
         using Visual Tree Assessment (VTA) from Mattheck (1994 & 1999), with
         additional references from Matheny & Clark (1994), and Harris (1999 &
         2004). Any risk assessment was done using Quantified Tree Risk Assessment
         (QTRA version 2007). Additional references to tree anatomy and structure are
         taken from Shigo (1986 & 1991), including references to roots from Perry
         (1982) and Urban (2008). Specifications on protection of trees and tree roots
         during construction activities are taken from AS 4970-2009 and BS
         5837:2005, including additional references from Urban (2008).

         Mr Clint Sloan of Matrix provided all information in relation to current plans,
         reports etc.

         A Pentax Optio A30 digital camera set on the highest resolution possible (10
         Mega pixels) was used for photographic documentation. A diameter tape was
         used for all measurements, giving an average diameter based on the
         circumference measurement. Diameter at Breast I (eight (DBH) was taken at
         1400mm above ground level on the highest side of the trunk, or as per
         AS4970-2009.

         No soil or root excavation assessment was carried out during the time of
         inspection. Root mapping where specified was done by obvious and visual
         signs of disturbance to the soil, surrounding structures and obvious surface
         roots.
