Arboricultural Impact Assessments

When submitting a development application to council, applicants must provide sufficient tree and site information for a Tree Management Officer to make a comprehensive assessment of the proposed works. An Arboricultural Impact Assessment (AIA) prepared by an AQF Level 5 arborist will assist council to process your application faster.

Tree Report prepares all AIA reports in accordance with Australian Standard AS4970-2009 Protection on Trees on Development Sites and Australian Standard AS4373-2007 Pruning of Amenity Trees by AQF Level 5 arborists and satisfy council requirements for submission to get your development under way.

Tree Risk Assessments

Tree safety management is a matter of limiting the risk of harm from tree failure while maintaining the benefits conferred by trees.

Tree Report are the experts in tree risk management and have prepared tree risk assessment reports for a wide range of audiences, such as private residential clients, primary & high schools, commercial sites and large infrastructure projects.

From 1 tree – 1000+ trees, Tree Report have you covered.

Our arborists are registered users of the Quantified Tree Risk Assessment (QTRA) system (Advanced Qualification).

By quantifying the risk from tree failure as a probability, QTRA enables a tree owner or manager to manage the risk in accordance with widely applied and internationally recognised levels of risk tolerance. QTRA further provides a decision-making framework which considers the balance between the benefits provided by trees, levels of risk they pose, and costs of risk management.
