List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.
There must be evidence that the individual has applied treatments to trees on at least one occasion according to work activity instructions for the following four situations:
control weeds
apply soil additives and ameliorants to the tree root system
apply plant-based mulch
implement soil de-compaction procedures using tools and equipment.
There must also be evidence that the individual has:
confirmed target trees and treatments required with supervisor
identified site hazards, assessed risks and confirmed controls with supervisor, including:
selected, checked and used personal protective equipment
confirmed availability of first aid equipment and emergency procedures
selected, prepared, calibrated and conducted pre-operational checks on tools, equipment and machinery according to operational and biosecurity procedures
identified and prepared chemical treatments according to manufacturer label instructions
carried out cleaning and maintenance tasks on site and equipment, including disposal of unused materials and waste safely according to environmental procedures
maintained records and reported according to workplace procedures.
All arboriculture work is required to be performed according to preferred industry practices (as outlined in the Companion Volume).
