Appendix 4: Explanation of Terminology
 Definition              Process Description
                         Complete tree removal leaving stump as close as possible to ground level.
                         Recommended process will include chipping of all foliage limbs and timber and
 Removal                 reinstatement of work site. Recommendation typically based on tree being assessed as
                         representing a health and safety concern [Dead, dying, structurally unsound, unstable,
                         poor form]
                         Complete tree removal to include grinding of stump to a depth of 75 millimetres unless
 Remove and              otherwise specified. Recommended process will include chipping of all foliage limbs and
 Grind                   timber and reinstatement of work site. Stump site will be cleaned of all grinding debris
                         and sawdust and backfilled with premium topsoil free from weeds.
                         Removal of all major/significant deadwood and dead branches up to [and including] 30
 Crown Clean             millimetres in diameter in trees overhanging pedestrian or vehicular areas or removal of
 (Deadwood)              dead branches > 50mm diameter in canopy of trees located in parkland or similar area
                         unless otherwise specified.
                         Recommended pruning process will include removal of broken, crossing, rubbing,
 Crown Clean             diseased, stressed or dying branches or limbs with poor attachment. Additional work
 (General                process may include pruning to define leaders, balance the crown, reduce weight load,
 pruning)                or clear the tree from obstructions. In summary, to rectify, as far as is possible, any
                         structural defects and eliminate undesirable growth or deadwood.

                         Recommended pruning process may include light and general pruning typically to

                         encompass removal of up to 15% but no more than 20% of the leaf-bearing crown. By

                         percentage [%] appropriate to species, condition and assessment.

                         Pruning processes maybe involve the raising of the tree’s lower canopy to a height
                         specified in metres. Typically, the process is performed to provide for pedestrian and or
                         vehicular clearance and unless otherwise specified the default parameters will be to

                         provide 2 metres clearance from ground level or as specified by local or state

                         government regulation. From time to time pruning requirements may be altered to
                         accommodate various site-specific requirements as advised by the consulting arborist
                         accordingly.
                         Pruning process will encompass crown restoration and remedial works where the tree
                         has been previously lopped or otherwise damaged. Not feasible when tree has extensive

                         decay and should only be considered when there is evidence of healthy re- growth.
 Restoration
                         When performed correctly the process of remedial pruning will most likely take several
                         years to complete.
                         Pruning process may be restricted to the removal of any hanger/s or

                         dangerous/dead/dying limbs and will typically involve the removal of a single limb. In

                         some instances, removal of an individual limb may be necessary to accommodate an

                         obstruction and the consulting arborist will advise accordingly.
                         Pruning process will be restricted to pruning canopy away from buildings/service
 Directional             wires/property boundary and will typically be performed to avoid future growth in these
 Pruning                 areas. Where appropriate future growth will be directed away from obstruction by
                         selected pruning so as to encourage the development of the growth of new leaders.
