Vegetation Management & Covenant Rehabilitation Plan

 

REVEGETATION SPECIFICATIONS
REVEGETATION DESIGN

The Covenant includes approximately 0.13ha of land within the southern extent of the
covenant area which is generally clear of vegetation precluding a low density of mature

Note that the dams and dam walls have been excluded from the revegetation area to
achieve the above conditions. However, they have been included within the assisted
natural regeneration area as weed management is still applicable in these areas.

Revegetation within denuded areas is to include species drawn from the species
palette listed in Table 3 to achieve the performance criteria listed in Table 1 (refer RP-
03). Plate D depicts an example of a denuded area requiring revegetation.

REVEGETATION METHODOLOGY

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 SPECIFICATIONS

Site Preparation

Existing exotic weeds within the Covenant Area are to be treated/removed a minimum
of three weeks prior to planting commencing. Refer to RP-03 for weed management
specifications.

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 a significantly 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’;

e 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

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.

Mulch

 

Each plant installed is to have a minimum 500mm x 500mm ‘ring’ of organic mulch (e.g.
sugar can mulch) applied to a depth of 100mm.
Plant Density
As agreed on site with Conor Neville of NSC, low density planting of canopy trees must
occur in the nominated reconstruction area. The following plant density is prescribed for
this purpose:

¢ Canopy Trees 1 per 9x9m?

Plant Numbers

An estimate of plant numbers required is provided below (based on 0.13ha). Final plant
numbers are to be determined by the amount of generally cleared area available
subsequent to weed control works.

e Canopy Trees - 16
Plant Diversity

The following minimum diversity must be implemented:
e Canopy Trees — No less than 4 species from Table 3

Planting Species Palette

A list of suitable species to be used is presented in Table 3. Additional species may be
used if they are locally indigenous to the Regional Ecosystem 12.11.10/12.11.2
rainforest / wet sclerophyll 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 conjunction
with advice from a specialist native plant nursery (e.g., Landcare).
