Attachment 6 - Arborist Statement

Explanatory Notes
•       Mathematical abbreviations: > = Greater than; < = Less than.

•        Measurements/estimates:       All dimensions are estimates unless otherwise indicated.
Measurements taken with a tape or clinometer are indicated with a ‘+’. Less reliable estimated dimensions
are indicated with a '?'.

•       Species: The species identification is based on visual observations and the common English name
of what the tree appeared to be is listed first, with the botanical name after in brackets. In some instances,
it may be difficult to quickly and accurately identify a particular tree without further detailed investigations.
Where there is some doubt of the precise species of tree, it is indicated with a '?' after the name in order to
avoid delay in the production of the report. The botanical name is followed by the abbreviation sp if only
the genus is known. The species listed for groups and hedges represent the main component and there
may be other minor species not listed.

•       Height: Height is estimated to the nearest metre.

•       Spread: The maximum crown spread is visually estimated to the nearest metre from the furthest
extent of live lateral branches on one side of the canopy to the tips of the live lateral branches on the
opposing side of the canopy.

•       Diameter: These figures relate to 1.5m above ground level and are recorded in centimetres. If
appropriate, diameter is measure with a diameter tape. ‘M’ indicates trees or shrubs with multiple stems.

•       Estimated Age: Age is estimated from visual indicators, and it should only be taken as a
provisional guide. Age estimates often need to be modified based on further information such as historical
records or local knowledge.

•        Distance to Structures: This is estimated to the nearest metre and intended as an indication
rather than a precise measurement.

Frass: A sawdust like after effect from wood and bark chewing/boring insects.

Tilth- The loosened effect of soil in the hole walls and floor.

Epicormic growth: Stress shoots, water shoots, re-growth or suckers. Poorly attached, quick growing.

Adventitious shoots: A branch arising from a stem or parent branch having no connection to apical
meristems.

SRZ: Structural Root Zone

TPZ: Tree Protection Zone

CRZ: Critical Root Zone

TPF: Temporary Protection Fencing



Basic VTA: Detailed visual inspection of a tree & surrounding site that may include the use of simple tools.
It requires that a tree risk assessor walk completely around the tree trunk looking at the site, above ground
roots, trunk & branches.
