REVEGETATION SPECIFICATIONS
REVEGETATION DESIGN

The Vegetation Protection Covenant includes approximately 0.487ha of land which is
host to managed grassland or modified areas denuded of canopy vegetation (refer
RP02 Plate B pink shading). These areas will require direct revegetation of suitable
native species into the denuded strata’s.
NOTE: The mapped Supplementary Revegetation Area extent on RPO2 is indicative
only and will require on ground confirmation/refinement of location and extent during
OPW.

Revegetation within the various strata’s 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. Undertake comprehensive weed control, including control/removal of woody weed
species as well as herbicide treatment of all herbaceous weeds and pasture
grasses.

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

4 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, roct
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 Be sun hardened.

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

Figure 1 - Tubestock Planting Specification
Waterin

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 ‘ting’ of organic mutch (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:

« Canopy Trees 5m centres

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

Plant Diversity
The following minimum diversity must be implemented:

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

Edge of Covenant Area (refer RP02 yellow linework)

A dense linear edge planting treatment is to be provided to the Supplementary
Revegetation area fronting managed grassland as follows:

*  1xrow of Lomandra longifolia 1m centres
«  1xrow of shrubs immediately behind row of Lomandra longifolia at 2m centres

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 12.11.10 Notophyll vine
forest. 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 conjunction with advice from a specialist native plant
nursery (e.g. Landcare).
