CAVEATS, LIMITATIONS, AND DEFINITIONS

The findings of this Tree Protection Plan are based on observations made at the time of
inspections prior to this Tree Protection Plan being prepared and from the information contained
within plans / documentation provided by the project team of consultants.

The Tree Protection Plan reflects the subject trees as found on the day of inspection. There is no
warranty or guarantee, expressed or implied, that problems or deficiencies with the site or the
subject trees may not arise in the future. Any changes to the development proposal or tree
management works beyond those recommended in this Tree Protection Plan may alter the
findings and recommendations of the Tree Protection Plan.

The methodology used in this Tree Protection Plan follows the procedures detailed in Australian
Standard: AS 4970—2009 Protection Of Trees On Development Sites. This Tree Protection Plan
also references the British Standard BS: 5837 (2005) Trees In Relation To Construction –
Recommendations. The references used in this Tree Protection Plan provides the following
information:

Tree species - botanical and common name, referenced on plan with a corresponding number.

DBH – Diameter at breast height (mm)

SRZ – Structural Root Zone radius (m)

TPZ – Tree protection Zone radius (m)



DBH (Diameter at Breast Height) - Stem /trunk diameter measured at 1.4m above ground level.
On sloping ground, measurements will be taken at the mid slope point at the base of the tree.
Where a tree stem / trunk begins to branch at a point that is less than 1.4m above ground, a
combined stem diameter is calculated using the formula: Total DBH = √ DBH2+ DBH2 + DBH2

SRZ (Structural Root Zone) – The area around the base of a tree required for the tree’s stability in
the ground. The woody root growth and soil cohesions in this area are necessary to hold the tree
upright. The SRZ is nominally circular with the trunk at its centre and is expressed by its radius in
metres.

TPZ (Tree Protection Zone) – A specified area above and below ground and at a given distance
from the trunk set aside for the protection of a tree’s roots and crown to provide for the viability
and stability of a tree to be retained where it is potentially subject to damage by development.
