URBAN FORESTRY AUSTRALIA - TREE MANAGEMENT & CONSULTING ARBORICULTURISTSDieback Death of growth tips/shoots and partial limbs, generally from tip to base. Dieback isoften an indicator of stress and tree health.End weight The excessive concentration of foliage at the distal ends of branches.Epicormic Shoots which arise from adventitious or latent buds. These shoots often have a weakpoint of attachment. They are often a response to stress in the tree.Epicormic growth/shoots are generally a survival mechanism, often indicating the presence of acurrent, or past stress event such as fire, pruning, drought, etc.Excurrent Tree where the trunk is erect, straight and continuous, tapering gradually, with themain axis clear from base to apex, e.g. Araucaria heterophylla Norfolk Island Pine.Hanger Unattached, cut or broken branches that are caught in the canopy.Hazard refers to anything with the potential to harm health, life or property.Health refers to the tree’s vigour as exhibited by the crown density, leaf colour, presence ofepicormic shoots, ability to withstand disease invasion, and the degree of dieback.Helical Shaped like a spiral or a helix. Especially wood fibres where the growth habit of a treetwists the fibres to resist stress loading from dominant wind flow by aligning fibres with the winddirection.Inclusion - stem/bark, the pattern of development at branch or stem junctions where bark isturned inward rather than pushed out. This fault is located at the point where the stems/branchesmeet. This is normally a genetic fault and potentially a weak point of attachment as the barkobstructs healthy tissue from joining together to strengthen the joint.Landscape Significance Rating.The importance of the tree as a result of its prominence in the landscape and its amenity value,from the point of public benefit.• Exceptional – Tree/s of crucial importance as a principal feature of a public place, or are sovisually prominent as to be a landmark feature.• High – prominent tree/s in private gardens or well-frequented public places.• Moderate – Contributes some amenity to the immediate garden/landscape areas, or to thestreetscape.• Low – Poor, declining or small examples; noxious or undesirable species; little or no visualamenity to public view.Resistograph® testing A Resistograph® is a specialised machine that measures timber densityby drilling a 3mm diameter probe through the wood, simultaneously plotting the results on a graphat full scale.Retention Value (RV) refers to the retention value of a tree, based on the tree’s Useful LifeExpectancy (ULE) and Landscape Significance.Risk The random or potentially foreseeable possibility of an event causing harm or damage.Scaffold branch/root A primary structural branch of the crown or primary structural root of thetree.Selective Pruning The removal of identified branches that are causing a specific problem.Arboricultural Audit and Assessment– Enmore Park, Marrickville.
