Learning Outcomes

This unit describes the skills and knowledge required to create and maintain habitat refuges in trees involving the installation of nesting boxes and the use of pruning techniques for habitat hollow and cavity creation in trees. It also involves the retention and positioning of materials from tree works for ground level habitat and refuges. 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 arboriculture work to create and maintain habitat refuges is undertaken according to preferred industry practices (as outlined in the Companion Volume). No licensing, legislative or certification requirements are to this unit at the time of publication.
