This unit of competency describes the skills and knowledge required to assess harvest sites and trees to be harvested and to plan and safely carry out manual tree-felling using a chainsaw as part of a commercial forestry operation. The unit covers the felling procedures for trees with a level of complexity that requires significant tree assessment and practical felling skills.Individuals competent in this unit should be able to effectively fell most trees except very large trees, and/or those with significant defects and/or characteristics that cause excessive complexity.Trees typical to the scope of this unit may have some of the following characteristics:lean and weight distribution that can be assessed and readily adapted to falling direction with the use of wedges and/or control with hinge-woodlimited visible damage and/or defectmulti-stemsforward lean, backward lean or side lean small or medium size diameter that can be safely felled with intermediate felling techniquesdead trees with minimal visible damage or defects that do not add significant complexity to the cutting techniquevarious dimensions relative to other trees when working in a forest environmentin local site conditions that add additional complexity to the felling operation, including site conditions that impact the working position of the operator or the natural direction of fall of the tree.The unit applies to individuals who fell intermediate trees as part of commercial forestry operations. All work must be carried out to comply with workplace procedures, according to state/territory health and safety regulations, legislation and standards that apply to the workplace.No licensing, legislative or certification requirements apply to this unit at the time of publication.
