K - Preliminary Arborist Report (29.08.2019)

02            METHOD & ASSESSMENT LIMITATIONS


The tree assessment summary presented in this report is based on a combined site
assessment with Gondwana Ecology Group on the 20th August 2019.


The historic site survey plan with noted significant trees (for purposes of Masters
development) within PDF file ‘2869-DA01_existing Masters Survey’ formed the foundation
of the Treescience assessment. Additionally, the drawing set by Buchan acknowledged the
covenant areas (Area A & B) which was also considered during our assessment from an
arboricultural perspective.


Prior to any onsite inspection(s) being carried out, a site survey plan and relevant drawings
were provided to Treescience in order to help identify and assess any potential impact of
the subject tree(s) within and adjacent to the proposed construction works. However, the
observations and recommendations within this report are, at this stage, speculative given a
detailed drawing of the site and proposed construction footprint is yet to be provided.


Since any part of a tree could fall, depending on the physical condition, it would be
clearly impracticable to undertake a detailed investigation of every part of every tree. The
subject tree(s) have been inspected visually while standing at ground level, using
binoculars as an aid where appropriate. Visual Tree Assessment (VTA) criteria was
employed to assess the mechanical integrity of the aerial parts of the subject tree as
proposed by Mattheck & Breloer (2002); with methods of hazard assessment as proposed by
Matheny & Clark (1994) and Lonsdale (1999).


By applying up-dated arboricultural principles and practices, the tree assessment consisted
of a comprehensive visual inspection of all parameters pertaining to the subject tree(s)
present and future health, and the influence of previous and future activities which may
have impacted the subject tree(s).


Soil characteristics and tree architecture were generally noted and/or analysed employing
standard industry tools such as optical laser equipment, measuring tapes, microscopes and
auger/coring devices etc.


The assessment did not involve a detailed examination of the below ground characteristics
or internal tree parts. The assessment was undertaken from the ground to determine tree
health, structure, form, and tree classification with measurements taken to establish trunk
and canopy dimensions.
