Elements and Performance Criteria

1. Determine implementation requirements of the tree protection program
   • Receive and interpret tree protection plan and specifications
   • Undertake a site-specific job safety analysis (JSA), record and implement control measures according to workplace safety procedures
   • Confirm availability of first aid equipment and emergency procedures
   • Identify and access tools, equipment and materials required to implement program
   • Determine, schedule and allocate tasks to work team, allowing for contingencies
2. Prepare site for tree protection
   • Identify location of tree protection zone from site plan
   • Select, prepare, and carry out pre-operational and safety checks, on tools, equipment and machinery
   • Select, check and use personal protective equipment
   • Survey the tree protection zone and delineate specified boundaries according to workplace procedures
   • Install protective barriers and signage according to tree protection plan
3. Install tree protection measures
   • Identify requirements for trunk, branch and root protection from tree protection plan
   • Select and assemble materials and equipment required to install tree protection measures
   • Construct and install protection measures specified in the program
   • Inspect completed protection measures and take remedial action where out-of-specification
4. Monitor protection program
   • Monitor tree health during scheduled program period
   • Assess effectiveness of protection measures during the scheduled period
   • Implement remedial action where tree health has been compromised
   • Dismantle and remove protection measures and fencing at conclusion of scheduled period
   • Clean, maintain and store tools and equipment according to workplace procedures
   • Update records and report tree protection outcomes according to workplace procedures

Performance Evidence

An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.

There must be evidence that the individual has demonstrated the ability to implement a tree protection program for at least two trees, including:

received and interpreted a tree protection program and identified:

trees to be protected

protection methods to use

schedule required

equipment necessary to perform work

assessed site-specific health and safety issues and completed a job safety analysis (JSA) and ensured first aid resources and emergency procedures were available

scheduled and allocated tasks to work team

surveyed and marked out the tree protection zone

erected barriers and signage

selected materials and equipment required for tree protection measures

conducted pre-operational safety checks and post-operational maintenance of equipment and tools

installed tree protection measures following specifications in plan

inspected completed protection installations and rectified where out-of-specification

monitored tree health during protection scheduled period and implemented remedial action where protection has been compromised

dismantled and removed protection measures

maintained records and reports of tree protection outcomes.

All tree protection work is required to be performed according to preferred industry practices (as outlined in the Companion Volume), including Australian Standard AS4970.
