Concept Covenant Area Rehabilitation Plan - 60 Glenridge Drive Cooroibah v1

 

 

REVEGETATION SPECIFICATIONS
REVEGETATION DESIGN

The Covenant includes approximately 8.4ha of land within the covenant area which is
host to harvested agricultural land. This area will require direct revegetation of suitable
native species to meet Condition 7 of Council's approval which states “Provide further
information as to the areas of the site to be revegetated”.

Revegetation within denuded areas is to include species drawn from the species
palette listed in Table 2 to achieve the performance criteria listed in Table 1 (refer RP-
03). Plate D depicts an example of a denuded area requiring revegetation.

SITE PREPARATION

The methodology for the revegetation program is to generally occur in the following
chronological order:

1. Clearly mark any existing native species that may be obscured within the weed
control areas to prevent incidental damage during site preparation and weed
control activities.

2. The direct supplementary revegetation areas are to be levelled to remove the relic
cropping rows/mounds, the final gradient should direct surface runoff towards the
onsite creeks.

3. Undertake comprehensive weed control, including control/removal of woody weed
species as well as herbicide treatment of all herbaceous weeds and pasture
grasses.

4. Once herbicide treatment has taken effect, plants can be installed.

5. Water in plants as required.

PLANTING METHOLOGY

Planting

Once weed treatment has taken effect, individual planting holes are to be manually dug
or by mechanical auger at the densities prescribed within this Plan. Plants are to be
provided as 50mm native tubestock. As a minimum, all tubestock is required to:

e Have asignificantly established root system;

e Not display signs of ‘yellowing’, leaf or stem damage or disease, root
curling/girdling or restriction related to being ‘pot bound’;

« Shrubs to have a single, straight trunk that is a minimum of 25cm tall for 50mm
tube-stock; and

e Besun hardened.

All tubestock is to be installed as per the Specification detailed in Figure 1.

Planting Species Palette

A list of suitable species to be used is presented in Table 2. Additional species may be
used if they are locally indigenous to the Regional Ecosystem Eucalyptus racemosa
subsp. racemosa woodland to open forest community. Where the species listed are not
available at time of works then similar native alternatives that occur within the local
vegetation communities may be utilised. Species substitution must be undertaken in

Watering

Planting is to occur as follows;

. Planting must not occur unless soil moisture is adequate;

. All stock must be watered immediately prior to planting;

. All planting holes are to be pre-watered prior to installation of tubestock; and

. Apply an initial establishment watering and continue to water as required to
ensure survival.

Mulch

Each plant installed is to have a minimum 500mm radius ‘ring’ of organic mulch (e.g.
sugar can mulch) applied to a depth of 100mm and adequate mulch covering must also
be present at the point of off-maintenance (i.e. minimum 50mm mulch coverage should
be available).

Plant Density
Replanting must occur with the following density:

e Canopy Trees 5m centres
« Small Trees 3m centres
« Understorey species 2m centres

Plant Diversity
The following minimum diversity must be implemented:

« Canopy Trees — No less than 5 species from Table 2
e Small Trees — No less than 5 species from Table 2
e Understorey species — No less than 3 species from Table 2

*NOTE: These species prefer wetter areas.

Management — Low Flammability Revegetation cies area

Condition 15 asks for details of management activities require to ensure safety and
meet the Bushfire Hazard Assessment recommendations within the 10m low
flammability area. The species palette selected for this low flammability area is
identified in Table 3 and was specifically chosen to allow the area to return to a natural
state with no management techniques required (e.g. mowing) whilst still maintaining the
low flammability characteristics.
