2023 Ecological Management Plan – Grasstree Court – Lot 9



          6. PERFORMANCE CRITERIA AND MONITORING

Monitoring of performance criteria is to occur annually for years 1-5. Performance criteria are based on practical
target outcomes for the rehabilitation following discussions with Council (and in accordance with the approval
condition requirements). Rehabilitation targets identified below that relate to tree species, survival, height and
density are addressed under the Stage 1 rehabilitation works and are already being monitored. The balance Stage 2
monitoring targets relate primarily to weed control (determined by the extent of soil placement over the balance
area). Overall Performance Targets to be achieved are as follows:

          •   Weeds (low) – dependent on treatment of weed infested areas adjacent to and surrounding the subject land
              and soil treatment.
      •       Mulch layer generally intact/mulch stockpiles are relatively weed free.
      •       Establishment (natural recruitment) of native species (dependent on condition and placement of soil from
              Lot 9).
      •       Survival of planted trees (high) – i.e. those already planted in Stage 1 works.
      •       Monitor erosion and stabilisation measures.

An initial report detailing the finished works and photo monitoring points will be completed once the On Maintenance
period has started (i.e. year 0).

Yearly reporting (years 1-5) will include the following:

      •       species list of all flora present within the treatment areas
      •       weed composition
      •       planted offset tree survival
      •       photos taken from the photo monitoring points
      •       other works (e.g. enhancement works, watering, weed control, etc.)

Specific Performance Criteria as follows:
Year One – 12 months after On Maintenance:
    i.        Planted trees 17 (i.e. koala feed trees) have achieved an average height of 1m.
   ii.        Planted shrubs/small trees (i.e. cockatoo feed trees) have achieved an average height of 0.5m.
Year Two/Three/Four – 24-72 months after On Maintenance:
    i.        Planted trees (i.e. koala feed trees) have achieved an average height of 2m.
    i.        Planted shrubs/small trees (i.e. cockatoo feed trees) have achieved an average height of 1m.
Year Five – 60 months - Final Off Maintenance:
    i.        Planted trees (i.e. koala feed trees) have achieved an average height of 3m.
   ii.        Planted shrubs/small trees (i.e. cockatoo feed trees) have achieved an average height of 2m.
  iii.        Plant density shading out and/or self-mulching (i.e. for plantings completed within Stage 1 works).
The duration of the on-maintenance period:
     i.       Adherence to maintenance regime for rehabilitation areas.
    ii.       No evidence of woody weeds reshooting from stumps, poisoned trees or the regrowth of cut stumps.
   iii.       No evidence of over-weeding or impact on non-target species.
   iv.        Signs of indigenous recruitment in rehabilitation areas.
    v.        Weed infestations less than 5% of the rehabilitation areas.
   vi.        Any failed plants within the previous 12 month period have been replaced.
  vii.        Healthy and vigorous growth allowed to grow to full form.
 viii.        Mulch layer sufficient to suppress weeds.
Ongoing liaison between contractors, project ecologist and Council is encouraged.

Reporting to Council for compliance with rehabilitation objectives is to be the responsibility of project ecologist. An
example monitoring sheet is provided as APPENDIX B2 (Monitoring Sheet - Rehabilitation).
