Develop an arboricultural impact assessment report

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


Performance criteria

Elements describe the essential outcomes.

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

1. Undertake assessment of trees on site

1.1 Identify and research relevant legislation and Australian Standards

1.2 Determine specific requirements of Statutory authorities in relation to trees on development site

1.3 Determine local government planning laws, tree protection and preservation regulations

1.4 Conduct a site assessment and identify conditions that impact tree protection program

1.5 Identify work health and safety hazards that impact safety of staff and public, assess level of risk and apply controls

1.6 Identify hazards, activities and circumstances that have potential to harm trees and assess the level of risk

1.7 Locate and confirm trees plotted on survey plan

1.8 Plot trees not on plan onto survey plan

2. Compile preliminary tree assessment data

2.1 Collect available relevant plans and documentation

2.2 Identify and record tree genus and species by botanical and common name

2.3 Record tree dimensions, height, crown spread and diameter-at-breast-height (DBH)

2.4 Determine age class and estimate life expectancy

2.5 Determine tree health in relation to tree physiology and pathology

2.6 Determine condition of tree structure in relation to tree anatomy

2.7 Consider heritage and cultural issues

2.8 Consider habitat, ecology and other matters relevant to the site

2.9 Consider location relative to existing and past site structures

2.10 Determine the retention value

2.11 Compile all tree assessment data required for report

3. Document preliminary arboricultural report

3.1 Record all trees and groups of trees suitable for retention

3.2 Determine indicative tree protection zone for each tree

3.3 Plot tree identifiers and indicative tree protection zone on survey plan

3.4 Document preliminary arboricultural report

4. Record impact of proposed development on trees

4.1 Interpret existing plans, working drawings, terms and symbols

4.2 Interpret development and design language

4.3 Consider how development can result in mechanical and chemical damage and determine appropriate controls

4.4 Determine impact of proposed development on trees

4.5 Provide preliminary feedback to client on potential areas of improvement

5. Determine indicative and actual tree protection zones

5.1 Assess development requirements for site access and logistics

5.2 Consider indicative tree protection zone

5.3 Determine extent of encroachment into indicative tree protection zone

5.4 Determine whether works will impact on structural root zone

5.5 Determine extent and area of structural root zone

5.6 Determine actual tree protection zone for trees to be retained

5.7 Define and record the actual tree protection zones

6. Demonstrate tree viability to major encroachment

6.1 Determine level of encroachment

6.2 Assess for a major encroachment: location and distribution of roots; potential loss of root mass; species tolerance to root loss; and age, health, size, lean and stability of tree

6.3 Consider impact of major encroachment on health, physiology and structural integrity of tree

6.4 Assess soil characteristics and volume and presence of existing or past structures and design factors

6.5 Consider how site and design factors minimise impact of proposed encroachment on tree

6.6 Demonstrate that the tree would remain viable

6.7 Determine additional remedial measures required

7. Develop protection measures and advise client

7.1 Develop an evidentiary portfolio of tree protection devices, techniques, tree-sensitive design and construction measures and tree responses to development activities

7.2 Specify protection devices, techniques and systems to minimise impact of development
