What are the relevant standards and policies for tree pruning? All tree pruning undertaken by the City is performed in strict accordance with the Australian Standard for Pruning of Amenity Trees (AS 4373-2007).
This standard provides the benchmark for best practice in arboriculture, ensuring any maintenance work supports the long-term health, structural integrity and natural form of the tree.
The City’s Urban Tree Planting and Maintenance Policy aligns with these principles, prioritising professional care over aesthetic or convenience-based pruning.
By adhering to these standards, the City ensures its maintenance practices are sustainable, reduce the risk of disease or decay, and retain the safety and beauty of our streetscapes for the entire community.
Does the City use suitably qualified contractors? Yes, the City maintains high standards for all tree-related work, regardless of whether it is performed by staff or contractors.
All contractors engaged by the City are required to have the same level of expertise as our staff, typically consisting of a combination of trade-qualified and management-level arborists.
These professionals must demonstrate a deep understanding of arboricultural practices and maintain strict compliance with the Australian Standard for Pruning of Amenity Trees (AS 4373-2007).
Can I prune my verge tree? You may prune small branches, under 3cm in diameter, using manual hand tools. Any work must be ground-based. Residents are not permitted to use ladders or climbing equipment.
You are not permitted to prune any trees located under or near powerlines, nor juvenile trees still within their 3-year maintenance period.
Any significant maintenance, including the removal of larger limbs, canopy reductions or work near utilities, must be carried out by the City’s qualified arborists.
If you are unsure whether your pruning needs fall within the guidelines, contact the City for an arborist assessment.
Resident Pruning Guidelines
Under what circumstances will the City prune my verge tree? The City prunes verge trees only when there is a clear safety or arboricultural requirement.
Primary reasons for pruning include:
- maintaining mandated clearances from power lines, street lighting and underground utilities
- ensuring safe sightlines for driveways, intersections and traffic signage
- ensuring footpaths and roads remain unobstructed for pedestrians and vehicles.
From a tree health perspective, City arborists may perform formative pruning on juvenile trees to improve their long-term structure, restoration pruning to help a tree recover from storm damage, or work to remove hazardous deadwood and structural defects.
Additionally, the City may prune branches overhanging private buildings, though this is subject to formal assessment and prioritisation based on the level of risk or encroachment.
All work is carried out to professional standards to minimise stress on the tree while protecting public and private infrastructure.
If you believe a tree requires pruning for any of these reasons, contact the City to request an arborist assessment.
My verge tree is under a powerline, when will it be pruned? The City runs an annual powerline clearance pruning program that encompasses all trees within road reserves, including those on residential verges.
This program is heavily influenced by site constraints, contractor availability and environmental factors, such as extreme weather that can make working near high-voltage lines unsafe.
For these reasons, it can be very difficult to provide specific timeframes for individual streets.
It is important to note even if a tree appears to be encroaching into the wires, it may not be pruned until its scheduled turn in the annual cycle. However, the City is committed to ensuring that every City-managed tree within the road reserve is pruned for essential safety clearances at least once per year.
Powerline Pruning
The City conducts an annual street tree pruning program using specialist arboricultural contractors. The municipality is divided into seven dedicated zones, with contractors working systematically through each area. This ensures required clearances from overhead powerlines, electrical infrastructure, and road network requirements are maintained in accordance with recognised arboricultural best practices.
When to contact the City
Lodge a request with the City if the below applies:
- If branches are touching the powerlines
- If branches are growing through the powerlines
How to lodge a request
To request tree pruning near powerlines, contact our Parks Services team on mail@bayswater.wa.gov.au and provide the street address and suburb.
My verge tree has been pruned right back, why? In certain circumstances, Western Power may intervene and prune City-managed trees without prior notice to the City in order to maintain emergency clearances.
My verge tree has been pruned by Western Power and branches have been left behind, can the City collect them? Yes. In certain circumstances, Western Power may intervene and prune City-managed trees without prior notice to the City in order to maintain emergency clearances.
When this occurs, the City will arrange for the collection of any resultant green waste left on the verge.
If debris has been left on your verge from Western Power’s pruning of a City-managed tree, contact mail@bayswater.wa.gov.au and we will coordinate a cleanup and inspection.
As Western Power’s priority is line clearance over tree aesthetics and long-term health, the City may also undertake restorative pruning, if required, to help the tree recover its form and health.
I don’t like the way my tree was pruned, can I request a particular pruning style? No, the City does not prune verge trees for aesthetic preferences or requested styles. All pruning is conducted by qualified arborists in strict accordance with the Australian Standard for Pruning of Amenity Trees (AS 4373-2007).
The primary goals of City pruning are to ensure public safety, maintain clearances for infrastructure (such as powerlines, roads and footpaths) and promote the long-term structural health of the tree.
The City understands residents may have personal preferences, however our arborists prioritise techniques that minimise stress to the tree and ensure it remains a safe and sustainable part of our urban forest.
Birds or other wildlife are creating a mess or living in my tree, can the City remove them or prune the tree? No, the City does not remove or disturb native birds, bees or other wildlife from trees. These animals are vital to the local ecosystem and are often protected under State and Federal environmental legislation. The presence of nesting animals or the sounds and debris associated with them are considered a natural part of our urban environment.
An exception may be made for bees if a hive is active in an area with high foot traffic or near sensitive infrastructure where they may pose a public safety risk. In these instances, the City will assess the situation and may engage a specialist to safely relocate or manage the hive.
Pruning of City-managed trees is only undertaken when there is a legitimate arboricultural need, such as maintaining public safety, structural integrity or infrastructure clearance. The presence of wildlife alone is not a reason for pruning or removal.
If you have concerns about the safety of a tree or a beehive in a high-traffic area, report it to the City for formal assessment.
Can I pay private contractors to prune my verge tree? No. Verge trees are City-managed assets and all pruning must be carried out or specifically authorised by the City. Residents are not permitted to engage private contractors to prune City trees.
Unauthorised pruning by private parties can lead to significant issues, including:
- Tree damage: Incorrect techniques can lead to disease, structural instability or the death of the tree.
- Safety risks: Working near roads and power lines requires specific insurance and safety protocols that City contractors are vetted for.
- Liability: Residents may be held liable for any damage to public infrastructure or injuries caused by unauthorised contractors.
If you believe a verge tree requires pruning, direct your request to the City for assessment by a qualified arborist.
