2023 Ecological Management Plan – Grasstree Court – Lot 9
The site has undergone scraping via excavator to expose bare sand /soil for the translocation material to be placed
upon and spread. All vegetative debris (waste) and topsoil layer scraped off the receiver site has been stockpiled (in
three piles in the east). This was completed by mid-2022.
Madeira vine was located on the rehabilitation site during the initial clearing for Stage 1. The weed material was
consolidated into a mound in the centre of the area for further treatment. Council undertook mulching (and
spreading) of the material in September 2022. This area is to be treated in accordance with the plans in APPENDIX B1.
With regards to the capping, “hold points” are to be verified by a Council Officer (or Contractor), noting that some
adjustment to stages and inspections may be required and agreed to suit construction sequence:
a) Confirmation that GCL has been placed as per the plans inclusive of batter drain GCL liner
b) Depth of confining layer cover over GCL
c) Depth of material above confining layer prior to planting
d) Batter drain and contour banks built to design
Council on-maintenance will be achieved subject to appropriate staged signoffs being confirmed.
Short term maintenance (5-year period in accordance with the EMP) of the rehabilitation area (including capping area)
remain the responsibility of Blue Care/Lendlease (and their contractors). The maintenance regime for the
rehabilitation works will also include the capping installation, with specific focus on monitoring and rectification of any
erosion.
The long term maintenance of the landfill (including the capping post the 5-year maintenance period) remains the
responsibility of Noosa Shire Council.
Once the initial works are completed, areas that have potentially unstable slopes will be addressed by way of erosion
control measures, including sediment fencing or coir logs (similar to those used for Stage 1 rehabilitation). This will be
determined on site and prior to on maintenance sign off.
4.4 Receiving Site Planting and Habitat Creation
Planting of canopy trees has been undertaken as part of Stage 1 works and includes trees to be planted for Stage 2.
While planting commitments have been met (to be monitored as part of Stage 1 works), additional planting is
proposed for Stage 2.
These works have been 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
Planting of trees has occurred as part of Stage 1 rehabilitation and includes:
• 670 she-oak from feed tree stock – tube stock, 140mm and 200mm
• 50 eucalypt and allied species – tube stock
• 350 other native species (local top the immediate surrounds and ecosystem) – tube stock
The balance rehabilitation area currently supports native trees (originally planted by Council) and which have been
retained through the initial selective clearing process. Further planting of canopy trees (300) is to be undertaken to
establish canopy/minimise competition with groundcovers species, recreate the woodland ecosystem, and enhance
koala habitat (i.e. planting of locally occurring suitable feed trees). She-oak trees are also proposed to be planted
(300) to enhance foraging resources for the glossy black-cockatoo. This will include she-oak grown from “feed tree
seed” and a selection of eucalypt appropriate to the rehabilitation area and suitable as koala feed trees, e.g. brushbox,
forest red gum, Moreton Bay ash, pink bloodwood 13.
13 These include species already planted by Council. Where needed, additional trees can be considered at on-maintenance.
