Ecological Management Plan — Grasstree Court — Lot 6

4. RECEIVING SITE REHABILITATION

4.1 Description and Tenure

 

The receiver site is located within the Girraween Sports Complex and Nature Refuge located at 100 Eenie
Creek Road; Noosa Heads (off Wallum Lane) and formally known as Lot 1SP239726. This area is owned by
Council ensuring that the rehabilitation efforts will be preserved indefinitely and located within close
proximity to the translocation site. A formal survey has located the boundaries for the receiver site and
treatment areas (FIGURE B2).

4.2 Treatment Areas

 

The area designated within this lot to receive the translocation treatments is approximately 3ha of
degraded land mapped as Category X (i.e. non-remnant) vegetation under Queensland state mapping.

The site currently consists of a bare hillside in the southern portion (T1). The balance area comprises a
weed infested area with scattered/few emergent trees (T2).

The total area of the receiver site is approximately 3ha.

e T1 area is approximately 3000m?.
o Consists of dune hillside, bare of vegetation with sandy, low nutrient soil.

e 712 area is approximately 27000m’.
o Consists of slight slope, dominated with weedy understory and few emergent trees.

The surrounding vegetation consists of a similar regional ecosystem composition to the subject land. It is
made up of a 50/50 ratio of RE12.2.5 and RE12.2.9.

Proximity to the development site, similar land zone, similar surrounding ecology, opportunities/desire® for

rehabilitation and long-term ecological benefit and protection justifies the suitability of the rehabilitation
site.

4.3 Receiving Site Preparation

 

The receiver site is to be prepared prior to any clearing works at the Lot 6 of the subject land. The overall
works involve weed removal from the surrounding buffer areas, weed removal from the T2 area, scraping
away the top layer of organic material at T2 area to expose clean soil substrate, installation of a mulch bund
along the bottom of the hillside to T2 area and placement of coir logs over T1 area to aid soil retention.
Once translocated soil is placed over entire T1 and T2 area, an irrigation watering system is to be installed.

Access is to be granted from Council. Areas to be designated for equipment storage, staff parking,
emergency meeting point and emergency access will be set up and signed. The TPZ of trees outside the
boundary will have fenced temporary with “NO GO” or similar signage.

The T1 area requires an access track to be installed so that machinery is able to enter the area and spread
out the live top soil. Coir logs will be placed along contours of the T1 area and secured with stakes. This will
aid in retaining the live soil mix once placed on the hillside.

The T2 area will undergo extensive weed removal. An excavator will be used to remove the bulk of the
weedy lantana which will be mulched on site. Native trees will be retained with minimum diameter at
breast height (DBH) of 25cm. TP2Z’s will be established as per AS4970: Protection of Trees on Development
Sites to ensure their survival throughout the works.
