Elements and Performance Criteria

1. Undertake assessment of trees on site
   • Relevant legislation is identified and researched.
   • Site is inspected.
   • Trees are located from site plans or working drawings to enable their identification.
   • Each tree in the program is assessed.
2. Provide design input
   • Trees are assessed for suitability for retention for the purpose of site design.
   • Optimal tree protection zone is determined for trees to be retained.
   • Design input relevant to retained trees is provided to the client or management.
3. Assess impact of development on trees
   • Existing plans and working drawings are interpreted.
   • Impact of proposed development on trees is determined.
   • Trees to be retained and removed are finalised and recorded.
4. Determine tree protection zones
   • Optimal tree protection zone is re-evaluated.
   • Site access and relevant logistics are assessed.
   • Available/actual tree protection zone is defined and recorded.
   • Additional remedial measures required are determined.
5. Develop protection measures and advise client
   • Appropriate protection measure techniques/systems to minimise impact are designed or developed.
   • Advice on tree removal and tree pruning is provided to client or management.
6. Document the relevant reports
   • An arboriculture assessment report is prepared.
   • Tree protection plans and guidelines are developed.
   • Tree management guidelines are prepared and documented.
   • Relevant reports, plans and guidelines are consolidated and presented to the client, management or relevant stakeholders.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following assess condition of trees on site assess impacts of development on trees determine tree protection zones determine suitable protection methods document arboriculture assessment report develop a tree protection plan and guidelines developdocument tree management guidelines
Context of and specific resources for assessment	Competency requires the application of work practices under work conditions Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances
