Tree Protection Guidelines
    •        Protection of retained trees during construction works

Protection of Retained Trees During Construction Works

An exclusion zone is to be established along the perimeters of retained trees and cordoned off with a
physical barrier of wire mesh fence, 1.8m in height, which is securely anchored. The role of these fences
is to prevent any damage to the complete tree including root system (SRZ & TPZ/NRZ), stem and branch
structure as well as the crown or canopy. Alternatively, and on approval of a minimum AQF Level 5
Project Arborist, plastic mesh fencing, 1.2m in height, secured with star pickets and caps with straining
wire can be utilised. All TPZ fencing will require appropriate signage to signify the relevant protection
zones. This will require audit and sign off prior to operational works onsite.




   Tree Protection Fencing to be utilised. Where works will be undertaken close to and within Tree
  Protection Zones specific tree protection measures to be utilised a directed by the project Arborist.


Project Hold Points
Engage a minimum AQF Level 5 Project Arborist during the project life;

    •        Once tree protection fencing and signage has been established and finalised. Project Arborist
             (minimum AQF Level 5) to audit and sign off.
    •        Any works within the NRZ of retained trees is required.
    •        If tree roots are encountered over 50mm in diameter outside of TPZs of retained trees.
    •        Changes to the plans occur.
    •        On completion of the project to conduct a final audit and summary.

(Site audits/summary reports will be conducted at each hold point interval by the Project Arborist)
