Learning Outcomes

This unit of competency describes the skills and knowledge required to identify and analyse aspects of tree biomechanics that affect the physical load and strength of trees, branches and anchorage in the ground. It requires the assessment of tree strength and the loads that occur, and the ability to assess factors that can weaken trees that increase the chance of failure. The unit applies to individuals with highly specialised advanced theoretical and technical knowledge for professional work and research in arboriculture. They exercise advanced cognitive, technical and communication skills and demonstrate complete autonomy, judgement and adaptability in research and analysis for complex problems. No licensing, legislative or certification requirements apply to this unit at the time of publication.
