Tree Risk Assessments

Tree Risk Assessments Melbourne

 

Professional assessment of tree-related risk for homeowners, businesses, schools, owners corporations and property managers.

​

Trees are living structures whose condition and surrounding environment can change over time.

​

Where there are concerns about branch failure, whole-tree failure or potential harm to people and property, a systematic tree-risk assessment can help determine an appropriate and proportionate response.

​

ArborSolve provides independent assessments using recognised methods, including ISA TRAQ and QTRA where suitable.

​

When Should a Tree Be Assessed?

 

A risk assessment may be appropriate where:

  • A large branch has failed

  • Cracks, cavities or decay are visible

  • The tree has developed a significant lean

  • Roots have been cut or disturbed

  • Soil movement is visible

  • Construction has occurred near the tree

  • The tree has been exposed by nearby clearing

  • Storm damage has occurred

  • The tree is near a dwelling, school or road

  • A property manager requires documented advice

  • Council or an insurer has requested an assessment

  • There has been a noticeable change in condition

​​

What the Assessment Considers

 

The assessment may consider:

  • Tree species and dimensions

  • Health and vitality

  • Trunk, branch and root condition

  • Visible structural defects

  • Previous failures

  • Previous pruning

  • Site exposure

  • Soil and rooting conditions

  • Potential targets

  • Frequency of occupation

  • Likelihood of failure

  • Likelihood of impact

  • Potential consequences

  • Suitable mitigation options

​​

ISA TRAQ Assessments

 

ISA Tree Risk Assessment Qualification provides a structured approach to assessing tree condition, potential failure, targets and consequences.

​

The resulting assessment can assist tree owners and managers in making informed decisions about pruning, monitoring, access management, further investigation or removal.

​

Quantified Tree Risk Assessment

 

QTRA provides a framework for assessing and managing risk from falling trees while recognising the benefits trees provide.

​

It may be suitable for individual trees, larger properties, commercial sites and organisations requiring a consistent risk-management approach.

​

Assessment Options

 

Ground-Based Visual Assessment

A systematic inspection from ground level using normal visual assessment tools.

​

Detailed Assessment

Additional investigation of a specific defect or part of the tree. This may involve climbing, aerial access, sounding, probing or specialist testing.

​

Multiple-Tree or Site Assessment

Assessment of a tree population across a school, commercial property, owners corporation or other managed site.

​

Possible Recommendations

 

Recommendations may include:

  • No immediate work

  • Periodic inspection

  • Deadwood removal

  • Selective branch reduction

  • Load reduction

  • Target or access management

  • Aerial inspection

  • Diagnostic testing

  • Monitoring of an identified defect

  • Root-zone protection

  • Removal where risk cannot reasonably be reduced

 

No tree can be declared completely safe.

 

The purpose of the assessment is to identify foreseeable concerns and recommend proportionate management based on the observed conditions.
