8. Appendix 2 - 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.
SRZ: Structural Root Zone
TPF: Temporary Protection Fencing
Adventitious shoots: A branch arising from a stem or parent branch having no connection to apical
meristems.
SRZ: Structural Root Zone
CRZ: Critical Root Zone
