Ecological Management Plan – Grasstree Court – Lot 9


The site will undergo earthworks via an excavator to expose bare sand /soil for the translocation material to be placed
upon and spread. All vegetative debris (waste) scraped off the receiver site will also be stockpiled for a minimum of
three months or taken to the local waste facility.

Madeira vine was located on the rehabilitation site during the initial clearing for Stage 1. This invasive weed has been
cordoned off and will be treated separately in consultation with Council. It is proposed that the weed will be
consolidated into a stockpile, burned and covered with soil to be subsequently rehabilitated.

4.4 Receiving Site Planting and Habitat Creation
Planting of canopy trees to be undertaken to achieve the following:

     •      approval conditions regarding cockatoo feed trees
     •      establish canopy/minimise competition with groundcover species
     •      recreate woodland ecosystem
     •      enhance koala habitat (i.e. planting of locally occurring suitable feed trees) in the locality

Once the stage 2 area has been covered with the translocated soil material, a minimum 9 of an additional 300 she-oak
trees (part of the offset glossy black-cockatoo trees) will be planted in the area. A minimum of 50 eucalypt (and allied)
species will also be planted as tube stock during this stage.

This will allow for trees to be included within the maintenance period. As works progress, consultation with the
landscape contractor/ecologist and Council will determine the final number and location of trees to be planted.

Two Glossy Black-cockatoo nest boxes are to be installed in suitable trees as part of stage 1 rehabilitation.

4.5 Irrigation and Watering
A watering system is to be installed on the receiver site once stage 1 translocation works have been completed. It will
consist of a primary irrigation line to be installed along the top of the hill / western boundary of T1 and T2 with
secondary irrigation lines running from the main line throughout T1 and T2.

It will be connected to either a tank and pump system located at the northern point of T2 or connected via a pipeline
to a temporary water connection at the sewerage treatment plant. Water will be required to be trucked to fill tanks if
temporary water connection and access to recycled water from the sewerage treatment plant is not obtained.

Infrastructure is to be put in place after all earthworks machinery is no longer needed on the site. Final alignment of
infrastructure will be decided on ground based on local conditions once works have been completed. This system will
allow watering to be done on an as needed basis over the 5-year maintenance period.

The Receiving/Rehabilitation Site Set-out is provided 10 in FIGURE B4.
