Perform pruning operations

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Reference books for 'Perform pruning operations' on This online store has a huge range of books, pretty reasonable prices, free delivery in Australia *and* they give a small commission to for every purchase, so go nuts :)

Elements and Performance Criteria


Performance criteria

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Prepare for pruning operations

1.1 Determine location of above-and-below-ground services

1.2 Undertake a site-specific risk assessment by identifying work health and safety hazards and assessing risk

1.3 Receive pruning instructions from supervisor and clarify prior to undertaking work

1.4 Confirm first aid, rescue personnel, equipment and procedures

1.5 Communicate with work team during operations using voice, hand and whistle signals

2. Determine requirements of pruning work

2.1 Identify and confirm location of tree to be pruned

2.2 Inspect trees for access and work

2.3 Determine type, extent and limit of pruning work in accordance with specifications, scope of works and client brief

2.4 Maintain awareness of power line proximity, safe approach distances and clearances

3. Select and prepare tools and equipment

3.1 Select appropriate tools and equipment for pruning

3.2 Consider access and impact value of secateurs, handsaws, chainsaws and polesaws

3.3 Carry out pre-operational and safety checks on pruning tools and equipment

3.4 Select and use personal protective equipment

3.5 Sterilise pruning equipment in between individual tree work in accordance with hygiene and biosecurity considerations

3.6 Record and implement work health, safety, site, environmental and traffic control measures

4. Determine tree part to be removed

4.1 Investigate stem bark ridge, old cuts, dead branches and occluded and occluding branches

4.2 Determine separate parts to be a branch or co-dominant stem in relation to tree anatomy and branch attachment

4.3 Determine the part requiring removal to be a branch or co-dominant stem to select the appropriate pruning procedure

5. Carry out branch pruning operations

5.1 Use sharp pruning tools to make clean cuts

5.2 Operate chainsaws and polesaws as required to implement pruning cuts to the standards required by AS 4373

5.3 Apply compartmentalisation of decay in tree (CODIT) principles

5.4 Pre-cut or undercut branches to avoid splitting or tearing

5.5 Remove remaining stub with final cut

5.6 Observe final cut procedure for branch removal cutting as close as possible to the branch collar without cutting into the branch collar or leaving a protruding stub.

5.7 Use branch bark ridge to determine angle of cut when removing a branch in the absence of a visible collar

5.8 Ensure bark at edge of all branch pruning cuts remains firmly attached

6. Carry out reduction pruning

6.1 Use branch bark ridge as guide to angle and position of final cut when making reduction cuts

6.2 Ensure lateral branch to which the final cut is made, is at least one third of diameter of branch being reduced at point of final cut.

7. Carry out stem pruning operations

7.1 Use stem bark ridge to determine angle of cut when removing a co-dominant stem

7.2 Be guided to position and angle of final cut, by positions and angles of joins between tissue of declining or dead stems and those of healthy stems elsewhere in tree

7.3 Ensure bark at edge of all stem pruning cuts remains firmly attached

8. Improve pruning quality

8.1 Inspect past pruning cuts to determine tree response

8.2 Use tree response to assess the quality of past pruning cuts

8.3 Seek feedback on pruning from other arborists

8.4 Identify and rectify incorrect pruning cuts

8.5 Modify future pruning cuts based on tree responses and feedback from others

9. Complete pruning operations

9.1 Drop pruning material into designated drop zone

9.2 Clean, maintain and store tools and equipment

9.3 Collect and dispose of, or recycle pruned material in a manner that causes minimal environmental damage

9.4 Maintain workplace records
