What Is an Arborist Report, and When Might Council Require One?
An arborist report is a written assessment of a tree prepared by a suitably qualified arborist. It records details such as the tree’s species, size, health, structure and location, then considers how proposed work or development could affect it. In South East Melbourne, a council may request a report when a planning application involves trees that could be protected by a local planning scheme, a planning permit, or another relevant control.
What does an arborist report cover?
The report is tailored to the question council needs answered. It may assess whether a tree is healthy or hazardous, explain its condition and likely useful life, and identify its root protection area and canopy spread. For a building or landscaping proposal, the arborist can assess possible impacts from excavation, access, changes to ground levels, paving or construction near the tree.
Reports commonly include photographs, a site plan showing tree locations, and practical recommendations. These may include design changes, protection fencing, limits on excavation, or monitoring during construction. A report is an assessment, not approval to remove or prune a tree.

When might council require one?
Council may ask for an arborist report as part of a planning application if a proposed development could affect a significant https://treeremovalsoutheastmelbourne.com.au/stump-grinding/ or protected tree. This can include building near a tree, removing or heavily pruning it, changing the site around its roots, or proposing works on a property subject to a tree-related planning control. A report may also be requested when council needs expert information to assess a tree’s condition, risk or contribution to the site.
Requirements vary across South East Melbourne. Each municipality has its own planning scheme provisions, permit conditions and application requirements, and protections can depend on the tree’s location, size, species or planning overlays. A tree that is not covered by one control may still be affected by another. Check with the relevant council before arranging work, and do not assume that being on private land means a tree can be removed without approval.
How to prepare and use the report
- Ask council’s planning or arboriculture team what information it needs and whether it has a preferred report format.
- Engage an appropriately qualified arborist with experience in development assessments; ask about relevant qualifications and insurance.
- Provide the arborist with the site plan and details of proposed buildings, access, drainage and earthworks.
- Submit the report with your application and allow time for council to assess it or request further information.
Why an early assessment helps
Getting advice before finalising plans can help identify tree constraints while design changes are still practical. It may also help your project team plan suitable tree-protection measures and avoid delays caused by incomplete application information. Confirm current requirements directly with your local council, as permit rules and application guidance can change. If council requires a report, follow its instructions and ensure any approved tree-protection measures are included in the construction plans.
