Elements and Performance Criteria

ELEMENT 

PERFORMANCE CRITERIA 

1. Prepare to apply tree treatments

1.1. Trees requiring treatments are located and the treatment determined according to work procedures.

1.2. Occupational Health and Safety (OHS) hazards are identified, risks assessed and reported to the supervisor.

1.3. Tools and equipment appropriate to the task being undertaken are prepared and used according to supervisor's instructions and enterprise guidelines.

1.4. Personal Protective Equipment (PPE) is selected and used according to enterprise OHS requirements.

2. Modify trees to alleviate stress

2.1. All dead, fractured, poorly attached, dying and diseased wood is removed at the designated position according to Compartmentalisation of Decay in Trees (CODIT) principles.

2.2. Competing branches are removed to allow adequate space for the natural form of the tree.

2.3. Growth patterns are re-directed to avoid physical and structural damage to the tree.

2.4. Removed plant material is disposed of according to enterprise guidelines and with due regard for environmental implications.

3. Modify environment to maintain health and vigour of tree

3.1. Competing plants are removed to ensure adequate space; light, water and nutrient requirements of the tree are maintained.

3.2. Nutrient additives are applied to the soil at rates and designated location according to supervisor's instructions.

3.3. Soil structure is ameliorated according to supervisor's instructions.

4. Apply treatment

4.1. Application equipment is checked for volume calibration, adjusted and operated according to manufacturer's instructions and enterprise guidelines.

4.2. Treatments are applied following manufacturer's instructions, enterprise guidelines and in accordance with OHS requirements and with due regard for environmental implications.
