Range Statement
Performance Evidence
The candidate must be observed removing a tree in a confined space using directional felling and removing a tree in a confined space using a dismantling process. The candidate must be assessed on their ability to integrate and apply the performance requirements of this unit in a workplace setting. Performance must be demonstrated consistently over time and in a suitable range of contexts.
