Environment Management Plan Stage 2_Grasstree Court July 2021

Ecological Management Plan – Grasstree Court – Lot 9


Stage 2 works to be completed as follows:

Step      Action
  1       Irrigation installed into stage 1 to continue irrigation line into balance (stage 2) area.
          Site soil (topsoil and subsoil) from Lot 9 transported and installed into the balance site (approx. 2ha).
  2       Install she-oak tubes (i.e. from project site seed) into the stage 2 area (and other trees as needed).
          Treatment to T1 (e.g. coir logs) and soil/seed.
  3       Ensure monitoring points cover all of rehabilitation site.
  4       Ongoing weed management.



2.2 Soil Seed Bank Transfer
Once the site (Lot 9) is cleared and all above ground material is mulched and stockpiled, earthworks machinery will be
used to scrape the top 200-300mm of soil off the ground at the translocation site. This will be placed immediately into
a truck and driven to the receiver site. Approximately 2ha 5 (area) of soil is to be translocated from Lot 9 to the
receiver site.

Once transported to the receiver site, the soil is unloaded directly into balance area, and trucks return to subject site.
Earthworks machinery will spread the unloaded soil as soon as is practicable over the pre-prepared area. Soil is to be
stockpiled for the shortest amount of time possible to retain seed viability. It is acknowledged that some stockpiling is
unavoidable. Stockpiling of live soil will be dependent on how quickly it can be spread out as well as the rate of
removal from Lot 9. Subsoil and topsoil to be treated separately with topsoil placed above the subsoil.

Mulch that is stockpiled throughout Lot 9 will also be transported to the receiver site in trucks and spread over the live
soil mix. This transfer will occur simultaneously with the soil transfer and mulch will be spread out over the receiver
site as soon as is practicable to retain any viable seed within the mulch piles.



2.3 Clearing Methodology
The clearing methodology (project site) to be generally as follows:

      •    Implement fauna spotter and habitat protection/identification measures as described above.
      •    Once the trees within the area have been given the “all clear” from the fauna spotter catcher, the trees will
           be pushed over using controlled felling techniques with a hydraulic excavator.
      •    Fauna spotter catcher will be present for all clearing works.
      •    The vegetation will then be placed in a windrow with a north/south alignment as it is being pulled down. This
           will be repeated until all the vegetation required to be removed to facilitate the development has been
           knocked over and piled into windrows. Once all the vegetation has been knocked down, another excavator
           will be used to downsize the material ready to be mulched.
      •    A grinder will then be used to process the material into stockpiles throughout the site.
      •    Note specific (selective and manual) clearing within the bushfire buffer areas.



2.4 Transporting Material
Material will be transported to the receiver site via the existing roadway network. The shortest route is approximately
seven minutes on public roads, pending traffic conditions (refer FIGURE B3 – Transport Route). Transportation of
material will occur in accordance with any specific traffic management plans, however, would aim to occur outside of
peak traffic periods.




      5 Balance rehabilitation area to receive soil from Lot 9 determined prior to soil transfer (note balance area approximately 2ha).

                                                                                                                                    23
