Perform a ground-based tree defect evaluation

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

Elements and Performance Criteria

Elements

Performance Criteria

Elements describe the essential outcomes.

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

1. Determine evaluation requirements

1.1 Confirm trees to be evaluated according to client brief

1.2 Undertake a site-specific job safety analysis (JSA) and record and implement control measures

1.3 Determine tree health and hazard benchmarks for project according to industry standards

2. Examine tree visually for indicators of potential failure

2.1 Examine tree for indicators of general poor health

2.2 Examine tree for visual defects

2.3 Examine tree for indication of damage from organisms

2.4 Assess examination outcomes to determine potential for structural failure of tree components according to industry benchmarks

3. Undertake basic testing of tree for indicators of potential failure

3.1 Conduct tests for cavities according to visual indicators

3.2 Expose root crown and examine for concealed root defects according to visual examination outcomes

3.3 Remove loose bark and examine stems for concealed defects according to visual examination outcomes

3.4 Assess test outcomes for potential impact on tree health and structural integrity according to industry benchmarks

4. Record tree attributes and indicators

4.1 Capture images and record botanical name, dimensions and location of tree under evaluation

4.2 Document the results of examinations and tests conducted for tree under evaluation

4.3 Capture images, location and visual indicators of defects in tree for inclusion in documentation

4.4 Estimate and record dimensions of defect and affected tree component

5. Assess and mitigate potential risk, and document actions

5.1 Identify possible targets affected by tree under evaluation from client brief

5.3 Validate assessment of severe defects on structural integrity of tree with consulting arborist

5.4 Advise client of outcomes of tree defect evaluation where a heightened potential risk to targets is identified

5.5 Take action to mitigate potential risk according to client advice and workplace policies and procedures

5.6 Document action taken to mitigate potential risk on target

6. Document and report hazards and recommendations

6.1 Review and assess tree defect evaluation results, and consider options for resolving any unmitigated risk

6.2 Identify and document recommended options for client approval

6.3 Compile records, results and recommendations, and document tree defect evaluation report according to workplace procedures and industry standards

6.4 Submit tree defect evaluation report to client according to workplace procedures
