Learning Outcomes

This unit of competency describes the skills and knowledge required to dismantle trees in close proximity to structures and other assets and in difficult or hazardous circumstances using a specialised range of methods, tools, equipment and materials and requiring the application of extensive arboricultural knowledge. The unit applies to individuals who work in arboriculture under broad direction and take responsibility for their own work. They use discretion and judgement in the selection, allocation and use of available resources and for solving problems. The arboriculture industry requires that all tree dismantling work is undertaken according to preferred industry practices (as outlined in the Companion Volume). Legislation, regulations and by-laws relating to the treatment and removal of trees apply in some states and territories.
