Tree audit

As part of its commitment to sustainability as well as high-quality property presentation, Goodman in Australia has approximately 20,000 trees located across its property portfolio.

Since trees are such a valuable resource that require ongoing management and maintenance, the Australian business identified the need to undertake a portfolio-wide tree audit and condition report.

Aim of audit

The aim of the audit was to primarily create a report which would:

  • Provide a centralised database detailing key information about every tree, including but not limited to location, species, age, health and health advice, structure, pest and disease guidance
  • Aid in the preservation of all trees across the portfolio
  • Develop a risk assessment matrix for which each tree could be assessed
  • Develop an ongoing maintenance plan for each tree.


Management together with an expert arborist developed the following best practice process:

  • Initial detailed tree assessment and documentation process
  • Tree inventory and mapping
  • Risk assessment matrix
  • Hazard and risk assessment adopting the risk assessment matrix
  • Implement a maintenance program
  • Tree preservation and master planning.


The key benefits of the audit have been:

  • Tree preservation
  • Hazard identification and risk prevention
  • Creation of a centralised database detailing all relevant information about each tree
  • Maintenance cost reduction
  • System to document subsequent works.
