10 T REE P ROTECTION S PECIFICATION S
The trees shown to be retained are to be protected from damage with temporary fencing as
specified in AS 4970:2025 Protection of Trees on Development Sites and this Arborist report.
Temporary fencing must be erected at the boundary of the TPZ/Exclusion Zone marked areas
and must be installed per AS4970 before works commence.

All works within a designated TPZ of retained vegetation must be supervised by the Project
Arborist (AQF Level 5).

Take all necessary precautions, including but not limited to the following:

•   Appropriate signage, i.e., ‘Tree Protection Zone’ and ‘No Go Zone’ must be erected at the
    boundary of TPZ to prevent vehicles from entering and prevent stockpiling from occurring
    near retained trees/vegetation.
•   No damage to be caused to tree trunks and bark (i.e., do not attach guides or stays to
    trees/vegetation).
•   No excavation works/open trenching to encroach within the TPZ of retained trees unless
    under the direct supervision of the Project Arborist.
•   Where necessary to cut roots, this shall be undertaken by the Project Arborist.
•   No storage or otherwise placing of spoil, bulk or potentially harmful materials (i.e.,
    construction refuse, concrete waste, herbicides, diesel, etc.) under or within 1m of TPZs.
    Prevent windblown materials such as cement from harming trees and plants.
•   Avoid ground compaction under trees. If compaction occurs (i.e., from site access or the
    location of a construction plant or vehicle parking), notify the Project Arborist and obtain
    their instructions.
•   Ground Protection: Where construction encroaches into the TPZ of trees to be retained,
    it shall be necessary to install protection to avoid compaction of the ground surface, lateral
    and absorbing roots.
•   Any damage to trees during work is to be rectified according to AS 4373/96 Pruning of
    Amenity Trees and best horticultural practices. The Project Arborist must oversee work.
•   Where deemed beneficial, mulch the entire ground surface within TPZ with Forest Blend
    Organic Mulch or site mulch to a depth of 100mm and install a temporary irrigation system
    or manually water to ensure that soil moisture levels are adequately maintained.
