Quantified Tree Risk Assessments (QTRA) & Tree Condition Reports

Azul Arboriculture provides Quantified Tree Risk Assessments (QTRA) and tree condition reports to help landowners, duty holders and managing agents understand and manage tree-related risk.

A QTRA assesses the likelihood of tree failure and the potential consequences, allowing risk to be quantified and managed proportionately. This approach supports defensible, evidence-based decision making, particularly where trees are located near roads, footpaths, buildings or areas of public access.

Our tree risk surveys are suitable for:

• Landowners and estates

• Local authorities and parish councils

• Schools and educational sites

• Commercial premises

• Residential developments

What Our Tree Risk Surveys Cover

Our tree condition and risk assessments include:

• Visual Tree Assessment (VTA)

• Identification of structural defects and decay

• Assessment of targets and site usage

• Quantified risk evaluation (QTRA methodology)

• Clear, prioritised management recommendations

Reports are written in clear, non-technical language and can be used to demonstrate compliance with duty of care obligations under health and safety legislation.

When Is a Tree Risk Assessment Required?

A tree risk survey is often required:

• Following storm damage or visible defects

• Where trees overhang highways, footpaths or buildings

• As part of routine asset management

• For schools, workplaces and public spaces

• To support insurance or legal requirements

Our arboricultural consultants provide proportionate advice, helping you manage risk without unnecessary tree removal.
