Unit of Competency AHCARB502A - Identify, select and specify trees
Description This unit covers the process of identifying, selecting and specifying trees and defines the standard required to: inspect and identify an extensive range of trees; determine the suitability of a tree for a purpose; evaluate and document the selection of trees; specification of replacement tree plantings; monitor and record quality control of selections; document a report of the identification, evaluation and specification process.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit applies to a wide range of applications in urban and regional areas and in local government and legal contexts in the specification of replacement trees in residential, commercial public open spaces and amenity areas.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Elements of Competency Performance Criteria              
Element: Identify a tree
  • Client is consulted and a brief developed and agreed.
  • Trees are identified for the purpose of the project/client brief.
       
Element: Determine the suitability of a tree for a purpose
  • Site inspection is undertaken according to the client brief and legislative and regulatory requirements.
  • Planting area dimensions are estimated for the tree species or cultivar.
  • Species and cultivar selection is appropriate to the available dimensions of the aspect and the site.
  • Soil volume is proportioned to the size of tree in consideration.
  • Environmental conditions are considered and applied to the functional characteristics of the tree.
  • The existing soil is appraised for suitability as a growth medium appropriate to the tree species or cultivar.
  • Functional life expectancy of site and plantings is determined.
  • The selection of the tree is evaluated and the rationale for tree selection is documented.
       
Element: Select trees
  • Trees are selected as per the client brief and their suitability for the intended purpose.
  • Tree function is determined for the precise location within the plan.
  • Recommendations are made for soil improvements in accordance with the tree species selected.
  • Species and cultivars are matchedappropriately to the determined selection criteria for species specific characteristics.
  • Tree species or cultivars for replacement or new plantings are recommended.
  • Tree selections, selection criteria and notes on quality expectations are documented as specifications.
       
Element: Specify trees
  • Criteria determined for size of stock selection are incorporated to the specifications.
  • Selection criteria for mature trees are evaluated against capability for transplanted trees.
  • Final selections are assessed against the specified soil, site location and client brief and confirmed.
  • Selected plants are monitored for quality and quantities according to the specifications.
  • Materials, soils and growing media are monitored for quality according to the specifications.
  • Records of quality checks on delivered plants and product are documented.
       
Element: Correlate and present a report
  • A report of the process is documented and the correlated records are incorporated.
  • The client or organisation is presented with the report.
       


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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:

inspect and identify an extensive range of trees

determine the suitability of a tree for a purpose

evaluate and document the selection of trees

specification of replacement tree plantings

monitor and record quality control of selections

document a report of the identification, evaluation and specification process.

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.
