Enmore Park Plan of Management - Land

URBAN FORESTRY AUSTRALIA - TREE MANAGEMENT & CONSULTING ARBORICULTURISTS4.2.5 Trees 20, 22, 24 and 27These are four (4) young Washingtonia filifera (American Cotton Palm),located within the development footprint. These palms can be readilytransplanted and be relocated to the positions shown on the concept parkmaster plan by Environmental Partnership (NSW).4.2.6 Tree 32The detail of the concept plans is insufficient to determine the extent of levelchanges near this tree. What is clear is that proposed bitumen and brickpaving affect the entire TPZ of the tree, and may result in the decline of thetree over time.4.2.7 Tree 36, 37 and 38.This trtes consist of one large Brush Box, and two large Moreton Bay Figtrees. Currently, there are tables and seating beneath the trees. Theproposal includes new seating on concrete slabs and a barbecue areabeneath the canopies of the figs, and paving around the root zone of theBrush Box.Although the proposed structures beneath the figs are isolated and wouldunlikely result in unacceptable loss of non-woody roots, there is potential fordamage to woody anchor roots within a 5 metre radius of the trees, i.e. theStructural Root Zone (SRZ). The final locations of the concrete pads,barbecues, and laying of any underground services in these areas will needto be subject to further assessment prior to finalising the design.The needs of the trees must also be considered, in that any exposed surfaceroots and a large area of the root zone must be protected from damage andsoil compaction. Foot traffic results in considerable compressive forces onthe soil surface, affecting the oxygen availability to roots and the ability forroots to penetrate the soil profile.Proposed brick paving around the root zone of the mature Brush Box isunlikely to benefit the tree. Consideration will need to be given to modifyingthe design to avoid covering the majority of the root zone with a pavedsurface.Arboricultural Audit & Development Impact Assessment– Annette Kellerman Aquatic Centre, Enmore ParkFebruary, 2009. 12 of 42
