Description
This unit of competency describes the skills and knowledge required to measure and improve the performance of trees.This unit applies to individuals with broad theoretical and technical knowledge of a specific area or a broad field of work and learning and cognitive, technical and communication skills to demonstrate autonomy, judgement and defined responsibility in undertaking complex work within broad parameters to provide specialist advice and functions.The role involves the self-directed application of specialised knowledge in arboriculture with substantial depth in areas of tree performance and carbon sequestration.No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.
