Do You Need an Arborist Report Before Tree Removal?

Tree removal isn’t always as straightforward as it seems. While property owners may see a damaged or unwanted tree as a simple job, local councils often have strict rules that determine what can and can’t be removed. In many cases, a detailed arborist report is required before approval is granted, particularly when a tree contributes to the character, safety, or ecosystem of the area.

A certified arborist report provides a professional assessment of a tree’s health, structure, and potential risks. It gives councils and property owners the information needed to make responsible decisions about removal or retention. Whether the tree is diseased, dangerous, or interfering with a development project, the report ensures that any action taken complies with local laws and best environmental practices.

When an Arborist Report Is Required

Many councils across South-East Queensland require an arborist report before a tree can be removed, especially when it is mature, native, or located close to property boundaries. These regulations exist to protect significant trees that contribute to local biodiversity, shade, and visual character. Some councils also regulate removals within specific overlays, such as conservation, vegetation protection, or heritage zones.

The need for a report often depends on the tree’s size, species, and proximity to nearby structures. For example, a healthy native tree with a trunk diameter above a certain threshold may need assessment, while smaller ornamental trees might not. In residential areas, a certified arborist provides the evidence required to show whether the tree poses a genuine risk or needs removal for safety or development reasons. Commercial and strata properties face similar rules, but approvals can take longer due to shared boundaries and higher public safety considerations.

What a Certified Arborist Assesses in the Report

An arborist report is far more than a visual inspection. Certified arborists use their training to evaluate both the visible and underlying factors that affect a tree’s safety, health, and long-term stability. Each report is detailed and supported by evidence that allows councils to make informed decisions.

Tree species, size, and location: Certain native or mature species are protected under local planning schemes, especially when they provide habitat or shade benefits.
Structural condition: Arborists inspect the trunk, canopy, and root zone for decay, cracks, or signs of weakness that could indicate potential failure.
Pests and disease: Evidence of borers, fungal growth, or internal decay is noted, as these can influence whether the tree can be treated or needs removal.
Root impact: The extent of root spread and its effect on buildings, driveways, or underground services are assessed to identify stability risks.
Environmental significance: Trees near waterways or within conservation overlays may require further environmental justification before removal is approved.
Recommendations: The arborist provides professional advice on whether removal, pruning, or other management options are most appropriate.

The report combines technical data and field observations to provide a balanced recommendation. This helps both property owners and councils reach the best outcome for safety, compliance, and environmental responsibility.

Why Councils Rely on Certified Arborists

Local councils depend on certified arborists to provide accurate, unbiased tree assessments that guide safe and lawful tree management decisions. These professionals have formal qualifications and field experience that meet the requirements set out by government authorities. Their reports are written to industry standards, outlining the tree’s condition, risks, and the reasoning behind any recommended actions. This level of documentation ensures that council officers can evaluate applications based on facts rather than assumptions.

Certified arborists also understand the environmental value of established trees and the impact their removal can have on ecosystems and neighbouring properties. Their assessments help councils balance safety concerns with long-term sustainability goals. By using a certified arborist, property owners demonstrate that their request for removal is both responsible and well-supported, reducing the risk of rejection or delays in approval.

What Happens If You Remove a Tree Without a Report

Removing a tree without the required arborist report or council approval can lead to serious consequences. These rules exist to protect the environment and public safety, so ignoring them can quickly become costly.

Fines and penalties: Councils can issue significant fines for unauthorised removal, especially when protected or native species are involved. In some cases, penalties can reach thousands of dollars per tree.
Delays to development projects: If removal occurs without documentation, councils may place a stop order on construction or renovation work until compliance is achieved.
Legal and insurance complications: Unapproved removal can void insurance claims for damage or liability, as it breaches local laws and safety codes.
Environmental and community backlash: Removing trees without cause can affect neighbourhood amenity, reduce shade, and attract complaints from surrounding residents or community groups.
Additional costs: Property owners may be required to replant replacement trees or commission retrospective reports, adding unnecessary expense and stress.

Working with a certified arborist from the start avoids these issues entirely. It ensures every decision is documented, justified, and compliant with local council regulations.

FAQ: Arborist Reports and Tree Removal

Not always. Requirements differ between councils and depend on the tree’s species, size, and location. In South-East Queensland, most councils need a certified report for native or mature trees that could affect public safety or local ecosystems.

Most reports can be completed within a few days after inspection, though complex properties or development sites may take longer. A detailed report includes photos, risk assessments, and recommendations for council review.

Only in certain cases. Trees that are dead, dangerous, or within specific exemptions may be removed without prior approval, but it’s always best to confirm with a certified arborist first. Acting without confirmation can lead to fines.

Reports include the tree’s identification, measurements, health assessment, structural condition, and recommendations for removal or management. They also reference relevant local council guidelines and environmental overlays.

The property owner or developer requesting the removal usually covers the cost. It’s a small investment that helps prevent costly penalties, project delays, or unnecessary disputes with council authorities.
