Application

This unit of competency describes the skills and knowledge required to remedy common tree problems by applying treatments including alleviating tree stress and improving soil condition. Treating trees also requires consideration of the environmental implications of treatment methods, techniques and procedures.

This unit applies to individuals who undertake defined activities, work in a structured context, apply knowledge and skills to demonstrate autonomy and limited judgement, and provide solutions to a limited range of predictable problems. Work is implemented with low risk work procedures and to comply with Safe Work Method Statement documentation.

Licensing, legislative, regulatory, or certification requirements apply to this unit in some states and territories at the time of publication, and may differ according to jurisdiction. Specific determination should be sought through the relevant State or Territory. Works involving this unit of competency may be subject to local tree protection and preservation laws, and the relevant content of applicable Australian Standards.

Pre-requisite Unit

AHCCHM201 Apply chemicals under supervision

Unit Sector

Arboriculture (ARB)

Assessment Conditions

Assessment must be demonstrated consistently over time in a suitable range of contexts and have a productivity-based outcome. No single assessment event or report is sufficient to achieve competency in this unit.

Assessment may be conducted in a simulated or real work environment, however determination of competency requires the application of work practices under work conditions.

The mandatory equipment and materials used to gather evidence for assessment include:

  • equipment:
  • spray application equipment
  • spill kit
  • measuring and weighing equipment
  • signage - chemical use
  • personal protective equipment (PPE)
  • first aid and emergency kit
  • traffic management kit
  • signage - work zone
  • trees
  • materials:
  • tree recognition form
  • hazard identification and risk control form
  • equipment and PPE check form
  • emergency preparation form
  • work communications form
  • chemical and treatment application form
  • tree maintenance form
  • soil assessment form
  • work site operations form
  • work records form

Assessors must satisfy current standards for RTOs in the assessment of arboriculture units of competency.

Assessment must be conducted only by persons who have:

  • arboriculture vocational competencies at least to the level being assessed
  • current arboriculture industry skills directly relevant to the unit of competency being assessed
