Analyse mycology cultures


Application

This unit of competency describes the skills and knowledge required to safely work within a laboratory environment, collect and identify wood decay fungi specimens, prepare in vitro cultures, and carry out primary experiments.

This unit applies to individuals with advanced theoretical and technical knowledge and skills for professional or highly skilled work and/or further learning in one or more disciplines or areas of practice. This unit applies to individuals with advanced cognitive, technical and communication skills to provide specialist advice, analyse, generate and transmit solutions to complex problems, and to demonstrate autonomy, well-developed judgement, adaptability and responsibility as a practitioner or learner.

The role involves the self-directed application of specialised knowledge in arboriculture with substantial depth in areas of tree pathology and mycology.

Work is performed under standard laboratory procedures of hygiene and safety for sampling, and use, sterilisation and cleaning of standard laboratory equipment and instruments.

No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.
