URBAN FORESTRY AUSTRALIA - TREE MANAGEMENT & CONSULTING ARBORICULTURISTSKEYARBORICULTURAL ASSESSMENTTrees to be retained. No special problemsvisibly apparent at time of inspection.Trees that require specific attention and/or furtherinvestigation of identified defects.Trees recommended for removal due topoor health and/or condition.DEVELOPMENT IMPACT ASSESSMENTTrees within or too close to the footprint of theproposed development.To be removed.Trees exempt from protection under the TPO or, oflow significance and could be readily removed andreplaced. To be removed.Significant trees, or trees of moderateto high retention value, which arepotentially affected by the proposal.NOTESAGL – Above Ground LevelARF- refers to the approximate diameter of a tree stem, immediately above the root flare.*H refers to the approximate height of a tree in metres, from base of stem to top of tree crown.*Sp refers to the approximate spread in metres, of branches/canopy of a tree.*DBH refers to the approximate diameter of tree stem at breast height i.e. 1.4 metres above ground (unless otherwise noted), and expressed in millimetres.*SULE refers to the estimated Safe Useful Life Expectancy of a tree. Refer to Appendix A -Terms and Definitions for more detail.*H refers to the tree’s vigour (health) as exhibited by the crown density, leaf colour, presence of epicormic shoots, ability to withstand disease invasion, and the degree of dieback.*C refers to the tree’s form and growth habit, as modified by its environment (aspect, suppression by other trees, soils, etc.) and the state of the scaffold (i.e. trunk and major branches),including structural defects such as cavities, crooked trunks or weak trunk/branch junctions. These are not directly connected with health and it is possible for a tree to be healthy, but in poorcondition.*Land sig. refers to the Landscape Significance Rating of a tree, considering the importance of the tree as a result of its prominence in the landscape and its amenity value, from the point ofpublic benefit.o Exceptional – Tree/s of crucial importance as a principal feature of a public place, or are so visually prominent as to be a landmark feature.o High – prominent tree/s in private gardens or well-frequented public places.o Moderate – Contributes some amenity to the immediate garden/landscape areas, or to the streetscape.o Low – Poor, declining or small examples; noxious or undesirable species; little or no visual amenity to public view.*RV refers to the retention value of a tree, based on the tree’s Safe Useful Life Expectancy (SULE) and Landscape Significance.*TPZ refers to the optimal tree protection zones for trees of ‘average to excellent vigour’. It is based on Matheny & Clark’s guidelines, as modified from the British Standards Institute 1991.Refer to Appendix A - Terms and Definitions for more detail.o All calculations for TPZ’s using the Matheny and Clark guidelines have been converted to metric figures.ooTrees of poor vigour are generally not considered for retention under this guideline.Canopy spreads displayed on the survey are not accurately shown in many cases. Where a TPZ is displayed as a smaller diameter than the crown dripline, it is to be given that theTPZ is to be extended to the canopy dripline.Arboricultural Audit & Development Impact Assessment– Annette Kellerman Aquatic Centre, Enmore Park.
