EXECUTIVE SUMMARY
Introduction
Ecology and Heritage Partners Pty Ltd was commissioned by ACCIONA Energy Australia Global Pty Ltd to
conduct a Biodiversity Assessment for the proposed underground transmission line intended to service the
Mortlake South Wind Farm. The purpose of the assessment was to identify the extent and type of remnant
native vegetation present within the study area and to determine the presence of significant flora and fauna
species and/or ecological communities.
Methods
A detailed desktop and literature review was undertaken, followed by a flora and fauna assessment on 12 and
13 February 2019 to obtain information on terrestrial flora and fauna values within the study area. A habitat
hectare assessment was undertaken in conjunction with the flora survey. Vegetation within the study area
was assessed according to the habitat hectare methodology, which is described in the Vegetation Quality
Assessment Manual Version 1.3.
Results
Flora
Remnant native vegetation in the study area is representative of two EVCs: Plains Grassland and Plains Grassy
Woodland. All remnants of recorded EVC’s were highly modified due to historical and ongoing agricultural
land use (ploughing, grazing), and are in poor to moderate condition.
A total of eight (8) scattered Small Trees were recorded within, or immediately adjacent to the study area.
These trees would once have been part of the Plains Grassy Woodland EVC, however the understorey
vegetation consists of predominantly introduced species (mainly exotic pasture grasses) and the trees no
longer form a patch of native vegetation.
Based on the highly modified and agricultural nature of the study area, heavy cattle grazing, landscape context
and the proximity of previous records, significant flora species are considered unlikely to occur within the
construction corridor due to the absence of suitable, unmodified habitat.
Fauna
Based on the modified nature of the study area and landscape context, significant fauna species are considered
unlikely to occur within the construction corridor.
Several wetland values are present within the broader landscape that are likely to provide habitat for wetland
and migratory fauna (i.e. Brolga Grus rubicunda). However, the project will not impact on any waterways or
wetlands that potentially support these species.
Marginal habitat for the nationally significant Growling Gras Frog Litoria raniformis is potentially present in
private land adjacent to the construction corridor. However, the action will not result in a direct or indirect
impact to the habitat.
Based on the poor condition of habitat within the study area and proximity of previously records, targeted
surveys for significant fauna are not required.

2.2 Field Assessment
The field investigations were undertaken in an area identified as the ‘construction investigation zone’ (Figure
2), and comprised:
50 metres either side of the alignment (excluding where this abuts road reserves) where the alignment
is in private land;
The entire width of the VicTrack rail reservation (Mortlake – Terang rail corridor); and,
Both sides of Bramich Lane, Keilambete Road and Riley Road.
2.2.1 Flora Assessment
A flora assessment was undertaken on 12th and 13th of February 2019 to obtain information on flora values
within the study area, and to identify potential habitat for species and ecological communities listed under the
Commonwealth EPBC Act and Victorian FFG Act.
12Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
The study area was walked, with all observed flora species recorded, any significant records mapped and the
overall condition of vegetation noted. Native vegetation in the local area was also investigated to assist in
determining the pre-European vegetation within the study area. EVCs were determined with reference to
DELWP pre-1750 and extant EVC mapping and their published descriptions (DELWP 2019b). The significance
assessment criteria of taxa and vegetation communities are presented in Appendix 1.
Where native vegetation was identified a habitat hectare assessment was undertaken following methodology
described in the Vegetation Quality Assessment Manual (DSE 2004).
2.2.2 Fauna Assessment
A fauna assessment was undertaken on 12th and 13th of February 2019 to obtain information on terrestrial
fauna values within the study area. The study area was visually assessed and active searching under and
around ground debris for reptiles, frogs and small mammals was undertaken. Binoculars were also used to
scan the area for birds, and observers listened for calls and searched for other signs of fauna such as nests,
remains of dead animals, droppings and footprints. Potential habitat for fauna was assessed, with an emphasis
on habitats that may provide shelter, food or other resources for significant species.
2.3 Removal, Destruction or Lopping of Native Vegetation (theGuidelines)
Under the Planning and Environment Act 1987, Clause 52.17 of the Planning Schemes requires a planning
permit from the relevant local Council to remove, destroy or lop native vegetation. The assessment process
for the clearing of vegetation follows the ‘Guidelines for the removal, destruction or lopping of native
vegetation’ (the Guidelines) (DELWP 2017).
2.3.1 Assessment Pathway
The Guidelines manage the impacts on biodiversity from native vegetation removal using an assessment
pathway approach. Two factors – extent of native vegetation and Location category – are used to determine
the pathway associated with an application for a permit to remove native vegetation. The location category
(1, 2 or 3) has been determined for all areas in Victoria and is available on DELWP’s Native Vegetation
Information Management (NVIM) Tool (DELWP 2019a). Determination of assessment pathway is summarised
in Table 1.

Notes: For the purpose of determining the assessment pathway of an application to remove native vegetation the extent includes anyother native vegetation that was permitted to be removed on the same contiguous parcel of land with the same ownership as thenative vegetation to be removed, where the removal occurred in the five-year period before an application to remove native vegetationis lodged.
13Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
2.3.2 Vegetation Assessment
Native vegetation (as defined in Table 2) is assessed using two key parameters: extent (in hectares) and
condition. For the purposes of this assessment, both extent and condition were determined as part of the
habitat hectare assessment.

Notes: Native vegetation is defined in the Victoria Planning Provisions as ‘plants that are indigenous to Victoria,including trees, shrubs, herbs and grasses’
2.3.3 Impact Avoidance and Minimisation
All applications to remove native vegetation must demonstrate the three-step approach of avoid, minimise
and offset. This is a precautionary approach that aims to ensure that the removal of native vegetation is
restricted to what is reasonably necessary, and that biodiversity is appropriately compensated for any native
vegetation removal that is approved. An avoidance and minimisation statement is included in Section 6.1.
2.3.4 Offsets
Offsets are required to compensate for the permitted removal of native vegetation. The resulting Native
Vegetation Removal (NVR) report detailing the offset obligations is provided in Appendix 3.
2.4 Assessment Qualifications and Limitations
Data and information held within the ecological databases and mapping programs reviewed in the desktop
assessment (e.g. VBA, PMST, Biodiversity Interactive Maps etc.) are unlikely to represent all flora and fauna
observations within, and surrounding, the study area. It is therefore important to acknowledge that a lack of
14Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
documented records does not necessarily indicate that a species or community is absent.
Ecological values identified on site are recorded using a hand-held GPS or tablet with an accuracy of +/-5
metres. This level of accuracy is considered adequate to provide an accurate assessment of the ecological
values present within the study area; however, this data should not be used for detailed surveying purposes.
The field assessment was undertaken during a sub-optimal season for the identification of flora and fauna
species (late summer). The ‘snap shot’ nature of a standard biodiversity assessment, along with sub-optimal
timing of the survey, meant that migratory, transitory or uncommon fauna species may have been absent from
typically occupied habitats at the time of the field assessment. In addition, annual or cryptic flora species such
as those that persist via underground tubers may also be absent. Targeted flora or fauna surveys were not
undertaken, as this was beyond the preliminary scope of the project. Nevertheless, the terrestrial flora and
fauna data collected during the field assessment and information obtained from relevant desktop sources is
considered adequate to provide an accurate assessment of the ecological values present within the study area.

3 RESULTS
3.1 Vegetation Condition
3.1.1 Remnant Patches
Remnant native vegetation in the study area is representative of two EVCs: Plains Grassland (EVC 132_61) and
Plains Grassy Woodland (EVC 55_61) (Figure 2). All remnants of recorded EVC’s were highly modified due to
historical and ongoing agricultural land use (ploughing, grazing), and are in poor to moderate condition.
The presence of these EVCs is generally consistent with the modelled extant (2005) EVC mapping (DELWP
2019b). The remainder of the study area comprises introduced and planted vegetation, present as crop,
pasture, windrows and ornamental plantings. Specific details relating to observed EVCs are provided below.
Plains Grassland
Plains Grassland is located in areas north and south of Sisters-Noorat Road (Figure 2). The cover of indigenous
perennial grasses is dominated by Common Tussock-grass Poa labillardierei, and Rush Juncus spp., with
scattered occurrences of Blown Grass Lachnagrostis spp. (Plate 1; Plate 2). Herb species recorded include
Small Loosestrife Lythrum hyssopifolia, Grassland Wood-sorrel Oxalis perennans and Slender Dock Rumex
brownii.

Plate 2. Low quality Plains Grassland within the studyarea (Ecology and Heritage Partners Pty Ltd12/02/2019).
16Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
Weed species, including Brown-top Bent Agrostis capillaris, Toowoomba Canary-grass Phalaris aquatica,
Cocksfoot Dactylis glomerata, Rye Grass Lolium spp. and Spear Thistle Cirsium vulgare were commonly found
throughout the remnant patches.
Plains Grassy Woodland
Plains Grassy Woodland EVC is located within the study area south of Londrigans Lane (east of Tapps Lane)
and within the Riley Road road reserve (Figure 2) (Plate 3; Plate 4). The tree canopy is absent, and when present
the shrub layer consisted of Blackwood Acacia melanoxylon. The understorey is dominated by native grasses
and sedge species, including Common Tussock-grass, Blown Grass, Rush, Small Loosestrife and Grassland
Wood-sorrel.
Weed species, including Toowoomba Canary-grass, Brown-top Bent, and Flatweed Hypochoeris radicata were
commonly found throughout many of the remnant patches. The Weeds of National Significance (WoNS) and
Victorian noxious weed African Box-thorn Lycium ferocissimum was also observed in these patches.

3.1.2 Scattered Trees
A total of eight (8) scattered Small Trees were recorded within, or immediately adjacent to the study area
(Figure 2e-2f; Plate 5; Appendix 1.4). These trees would once have been part of the Plains Grassy Woodland
EVC, however the understorey vegetation consists of predominantly introduced species (mainly exotic pasture
grasses) and the trees no longer form a patch of native vegetation.

Plate 5. Scattered tree within the study area (Ecology andHeritage Partners Pty Ltd 12/02/2019).
3.1.3 Introduced and Planted Vegetation
Introduced Vegetation
Areas not supporting remnant native vegetation have a high cover of exotic grass species (>90%), many of
which have been direct-seeded for use as pasture (Plate 6). Scattered native grasses are occasionally present
in these areas, however they did not have the required 25% cover to be considered a native patch as defined
by the Guidelines (DELWP 2017). Removal of embedded rock has also been undertaken to facilitate the direct
seeding of pasture grasses.
Disturbed areas were dominated by weeds such as Brown-top Bent and Toowoomba Canary-grass. Other
species present includes Cocksfoot, Rye Grass and Barley Grass Hordeum spp. (Plate 6).
Noxious weeds are present throughout the study area, with scattered occurrences of Spear Thistle, Hawthorn
Note: HU = Habitat Units; * = Minimum Strategic Biodiversity Value (SBV) is 80% of the SBV of the clearing site.
It should be noted that due to rounding protocols employed by DELWP, the offset quantum for the entire
alignment (0.888 General Units) does not equate to the offset quantum when split by municipality (0.889
General Units).
3.4 Significance Assessment
3.4.1 Flora
No nationally or state significant flora species were recorded within the study area during the field assessment.
A consolidated list of flora species recorded is provided in Appendix 1.1.
The VBA contains records of one nationally significant and eight State significant flora species previously
recorded within 10 kilometres of the study area (DELWP 2019d) (Appendix 1.2; Figure 3). The PMST nominated
an additional 15 nationally significant species which have not been previously recorded but have the potential
to occur in the locality (DoEE 2019).
Based on the highly modified and agricultural nature of the study area, heavy cattle grazing, landscape context
and the proximity of previous records, significant flora species are considered unlikely to occur within the
construction corridor due to the absence of suitable, unmodified habitat.
Recommendation
Targeted surveys are not required for significant flora within the study area.
21Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
3.4.2 Fauna
No nationally or state significant fauna species were recorded within the study area during the field
assessment. A consolidated list of fauna species recorded is provided in Appendix 2.1.
The VBA contains records of four nationally significant, 12 State significant and four regionally significant fauna
species previously recorded within 10 kilometres of the study area (DELWP 2019d) (Appendix 2; Figure 4). The
PMST nominated an additional 16 nationally significant species which have not been previously recorded but
have the potential to occur in the locality (DoEE 2019).
Based on the modified nature of the study area and landscape context, significant fauna species are considered
unlikely to occur within or immediately adjacent to the construction corridor. There is one dam located
adjacent to the construction corridor immediately south of Riley Road, Terang that is considered to provide
marginal habitat for the nationally significant Growling Grass Frog Litoria raniformis (Figure 2l). This dam is
located six metres from the edge of the construction corridor and as such, the works are not considered to
directly or indirectly impact this habitat.
Several wetland values are present within the broader landscape that are likely to provide habitat for wetland
and migratory fauna (i.e. Brolga Grus rubicunda). However, the project will not impact on any waterways or
wetlands that potentially support these species.
Recommendation
There are two records located 13 kilometres to the north, and one record 18 kilometres to the south of Riley
Road which indicates that the locality may support low numbers of Growling Grass Frog.
Due to the low quality condition and sporadic distribution of habitat features preferred by the species (as
described in the National Recovery Plan for the species [DSE 2012]), within the broader landscape, it is
considered unlikely that Growling Grass Frog would utilise this dam as foraging habitat, or rely on the habitat
for breeding purposes. As such, targeted surveys are not required as the project will not impact on any
waterways or wetlands that potentially support these species.
However, to mitigate any potential impact to Growling Grass Frog and aquatic habitat at this location, it is
recommended that any transmission line works avoid direct or indirect impact to the dam by locating any
digging/trenching works at least five metres from the waterbody.
Currently, the dam is located six metres from the edge of the construction corridor, and no direct or indirect
impacts to the species are considered likely to occur due to the absence of suitable habitat within the road
reserve of Riley Road.
Drift fencing should be established along the southern boundary of the construction corridor between the
cable and the dam, to reduce the likelihood of any fauna (frogs, small mammals, reptiles) gaining access to the
construction corridor and getting trapped in any trenches that are constructed at this location. The preferred
location of drift fencing is shown at Figure 2L.
If any works are to be located within five metres of the waterbody, targeted surveys for Growling Grass Frog
are recommended to be undertaken during the species breeding season (usually between October and
December).
22Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
3.4.3 Communities
No national or State significant communities are present within the study area.
Three nationally listed ecological communities are predicted to occur within 10 kilometres of the study area
(DoEE 2019):
Grassy Eucalypt Woodland of the Victorian Volcanic Plain;
Natural Temperate Grassland of the Victorian Volcanic Plain; and
Seasonal Herbaceous Wetlands (Freshwater) of the Temperate Lowland Plains.
However, vegetation within the study area did not meet the condition thresholds that define any national or
State-significant communities due the lack of structural diversity, dominance of exotic flora and absence of
key indicator species.
23Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
4 LEGISLATIVE AND POLICY IMPLICATIONS
4.1 Environment Protection and Biodiversity Conservation Act 1999(Commonwealth)
The Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) establishes a Commonwealth
process for the assessment of proposed actions likely to have a significant impact on any matters of National
Environment Significance (NES), as described in Table 6.
Table 6. Potential impacts to matters of National Environmental Significance (NES)
Matter of NES Potential Impacts
World Heritage properties The proposed action will not impact any properties listed for World Heritage.
National heritage places The proposed action will not impact any places listed for national heritage.
Ramsar wetlands ofinternational significance
The study area occurs approximately 18 kilometres east of the Western District LakesRamsar wetland – (DoEE 2019):
The proposed action is highly unlikely to impact the ecological character of any Ramsarwetland.
Threatened species andecological communities
No habitat for nationally significant flora or fauna species will be impacted (Section 3.4.1and 3.4.2). No ecological community listed under the EPBC Act were recorded within thestudy area (Section 3.4.3).
Migratory and marine species
Several wetland values are present within the broader landscape that are likely to providehabitat for wetland and migratory fauna. However, the project will not impact on anywaterways or wetlands that potentially support these species.
There is no marine habitat within the study area and the study area would not be classedas an ‘important habitat’ as defined under the EPBC Act Policy Statement 1.1 PrincipalSignificant Impact Guidelines (DoE 2013), in that it does not contain:
Habitat utilised by a migratory species occasionally or periodically within aregion that supports an ecologically significant proportion of the population ofthe species;
Habitat utilised by a migratory species which is at the limit of the species range;or,
Habitat within an area where the species is declining.
Commonwealth marine area The proposed action will not impact any Commonwealth marine areas.
Nuclear actions (includinguranium mining)
The proposed action is not a nuclear action.
Great Barrier Reef Marine Park The proposed action will not impact the Great Barrier Reef Marine Park.
Water resources impacted bycoal seam gas or miningdevelopment
The proposed action is not a mining development and will not impact water resources.
4.1.1 Implications
There is one dam located adjacent to the study area immediately south of Riley Road, Terang that is considered
to provide marginal habitat for one fauna species (Growling Grass Frog) listed under the EPBC Act. However,
the dam is located six metres from the edge of the construction corridor, with direct or indirect impacts to
24Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
habitat considered highly unlikely to occur. As such, the action will not result in a significant impact to Growling
Grass Frog, and a referral to the Commonwealth under the EPBC Act is not required. No other matters of NES
were recorded, or are considered likely to occur.
If any works are to be located within five metres of the waterbody, targeted surveys for Growling Grass Frog
are recommended to be undertaken during the species breed season (usually between October and
December).
4.2 Flora and Fauna Guarantee Act 1988 (Victoria)
The FFG Act is the primary legislation dealing with biodiversity conservation and sustainable use of native flora
and fauna in Victoria. Proponents are required to apply for an FFG Act Permit to ‘take’ listed and/or protected
flora species, listed vegetation communities and listed fish species in areas of public land (i.e. within road
reserves, drainage lines and public reserves).
4.2.1 Implications
No FFG Act - listed or protected species were recorded within or adjacent to the construction corridor during
the field assessments, and due to the highly modified condition of habitats, are considered unlikely to occur.
No FFG Act-list communities were recorded within the construction corridor. As such, a permit under the FFG
Act is not required.
4.3 Planning and Environment Act 1987
The Planning and Environment Act 1987 outlines the legislative framework for planning in Victoria and for the
development and administration of planning schemes. All planning schemes contain native vegetation
provisions at Clause 52.17 which require a planning permit from the relevant local Council to remove, destroy
or lop native vegetation on a site of more than 0.4 hectares, unless an exemption under clause 52.17-7 of the
Victorian Planning Schemes applies or a subdivision is proposed with lots less than 0.4 hectares1. Local planning
schemes may contain other provisions in relation to the removal of native vegetation.
4.3.1 Local Planning Schemes
The study area within the Moyne Shire Council is zoned as Farming Zone (FZ). No overlays apply to this area.
The following zoning and overlays apply to the study area within the Corangamite Shire:
Farming Zone – Schedule 1 (FZ1);
Public Park and Recreation Zone (PPRZ);
Road Zone – Category 1 (RDZ1); and
Public Use Zone (PUZ1).
Heritage Overlay (HO287).
1 In accordance with the Victorian Civil and Administrative Tribunal’s (VCAT) decision Villawood v Greater Bendigo CC(2005) VCAT 2703 (20 December 2005) all native vegetation is considered lost where proposed lots are less than 0.4hectares in area and must be offset at the time of subdivision.
25Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
4.3.2 The Guidelines
The Planning and Environment Act 1987 outlines the legislative framework for planning in Victoria and for the
development and administration of planning schemes. All planning schemes contain native vegetation
provisions at Clause 52.17 which require a planning permit from the relevant local Council to remove, destroy
or lop native vegetation.
Where the clearing of native vegetation is permitted, the quantity and type of vegetation to be offset is
determined using methodology specified in the Guidelines (DELWP 2017).
4.3.3 Implications
The study area is within Location 2, with 3.928 hectares of native vegetation currently proposed to be
removed. As such, the permit application falls under the Detailed Assessment pathway.
The offset requirement for native vegetation removal throughout the entire alignment totals 0.888 General
Habitat Units (HUs), with a minimum Strategic Biodiversity Value of 0.253. No Large Trees are required to be
offset.
Within each of the municipalities, the offset obligation breaks down as follows:
Moyne Shire: 0.526 General HUs with a minimum Strategic Biodiversity Value of 0.256; and,
Corangamite Shire: 0.363 General HUs with a minimum Strategic Biodiversity Value of 0.248.
It should be noted that due to rounding protocols employed by DELWP, the offset quantum for the entire
alignment (0.888 General Units) does not equate to the offset quantum when split by municipality (0.889
General Units).
A Planning Permit from the Responsible Authority is required to remove, destroy or lop any native vegetation.
4.4 Wildlife Act 1975 and Wildlife Regulations 2013 (Victoria)
The Wildlife Act 1975 (and associated Wildlife Regulations 2013) is the primary legislation in Victoria providing
for protection and management of wildlife. Authorisation for habitat removal may be obtained under the
Wildlife Act 1975 through a licence granted under the Forests Act 1958, or under any other Act such as the
Planning and Environment Act 1987. Any persons engaged to remove, salvage, hold or relocate native fauna
during construction must hold a current Management Authorisation under the Wildlife Act 1975, issued by
DELWP.
4.4.1 Implications
Any persons engaged to conduct salvage and translocation, or general handling of terrestrial fauna species
must hold a current Management Authorisation.
4.5 Catchment and Land Protection Act 1994 (Victoria)
The Catchment and Land Protection Act 1994 (CaLP Act) contains provisions relating to catchment planning,
land management, noxious weeds and pest animals. Landowners are responsible for the control of any
infestation of noxious weeds and pest fauna species to minimise their spread and impact on ecological values.
26Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
4.5.1 Implications
Weeds listed as noxious under the CaLP Act were recorded during the assessment (Spear Thistle, Hawthorn,
African Box-thorn, Sweet Briar, Blackberry, Willow, Golden Thistle and Gorse). Weed management measures
should be incorporated into the project Construction Environmental Management Plan (CEMP) to ensure the
risk of weed spread is minimised.
27Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
5 MITIGATION MEASURES
All applications under the Guidelines must demonstrate avoidance and minimisation of impacts to native
vegetation.
5.1 Avoid and Minimisation Statement
Due to the nature of the proposed works, and land constraints associated with the placement of the
underground transmission alignment, it is not possible to avoid impacts to native vegetation. However,
ACCIONA have demonstrated impact avoidance in several ways.
The results of the field investigations undertaken within an initial ‘assessment area’ (Section 2.2) were
provided to ACCIONA to allow the amended construction corridor to be designed and located to minimise
impacts to areas of native vegetation comprising the endangered Plains Grassy Woodland and Plains
Grassland EVCs where practical, particularly within the Mortlake-Terang rail corridor (Figure 2d – 2g) and Riley
Road (Figure 2k – 2o). The detailed design of the construction corridor has allowed for the retention of higher
quality areas of Plains Grassland and Plains Grassy Woodland vegetation recorded within the initial
‘construction investigation zone’. The construction corridor has also been designed to avoid any direct or
indirect impacts to the marginal Growling Grass Frog habitat on Riley Road (Figure 2l).
It should be noted that the construction corridor includes buffers to allow for unintended construction
impacts; however, this is a worst-case scenario, and impacts will be unlikely to extend this width along the
entirely of the construction corridor.
Thermal sand is used to insulate the cable and increase heat dissipation into the surrounding soil, enabling
electricity to flow through the cable with less resistance. As such, an open trenching methodology is required
to be used except in very limited circumstances. As such, it is not considered that boring is a feasible option
in this instance. ACCIONA has provided additional information in the Planning Application Report that
accompanies the planning permit application.
Given that the quality of native vegetation is low, and is limited to a low cover (approx. 25-30%) and diversity
of common grasses (Tussock Grass), rushes (Juncus spp.,) and Blackwood’s that have likely regenerated
naturally after previous disturbance in the now disused rail corridor, it is not considered that this vegetation
provides important habitat for significant flora and/or fauna, and the above avoid and minimise measures
implemented by ACCIONA are applicable in this instance.
5.2 Offset Strategy
Ecology and Heritage Partners are a DELWP accredited over-the-counter offset broker. We have two offset
sites listed within the Glenelg CMA region that are confirmed to contain native vegetation credits that can be
used to satisfy the offset obligations generated by the current proposal.
A fee proposal has been provided to the client to secure the offset obligations should a permit be issued for
the development.

5.3 Best Practice Mitigation Measures
Recommended measures to mitigate impacts upon terrestrial and aquatic values present within the study area
may include:
Ensuring any proposed works remain within the development footprint, i.e. not disturbing or removing
areas of native vegetation outside the proposed works area. This also applies to machinery storage,
materials stockpiles, personnel rest areas and access roads;
Minimise impacts to native vegetation and habitats through construction and micro-siting techniques,
including fencing retained areas of native vegetation. If indeed necessary, trees should be lopped or
trimmed rather than removed. Similarly, soil disturbance and sedimentation within wetlands should
be avoided or kept to a minimum, to avoid, or minimise impacts to fauna habitats;
All contractors should be aware of ecologically sensitive areas to minimise the likelihood of
inadvertent disturbance to areas marked for retention. Habitat Zones (areas of sensitivity) should be
included as a mapping overlay on any construction plans;
Tree Protection Zones (TPZs) should be implemented to prevent indirect losses of native vegetation
during construction activities. A TPZ applies to a tree and is a specific area above and below the
ground, with a radius 12 x the DBH. At a minimum standard a TPZ should consider the following:
o A TRZ of trees should be a radius no less than two metres or greater than 15 metres;
o Construction, related activities and encroachment (i.e. earthworks such as trenching that
disturb the root zone) should be excluded from the TPZ;
o Where encroachment exceeds 10% of the total area of the TPZ, the tree should be considered
as lost and offset accordingly;
o Directional drilling may be used for works within the TPZ without being considered
encroachment. The directional bore should be at least 600 millimetres deep;
o The above guidelines may be varied if a qualified arborist confirms the works will not
significantly damage the tree (including stags / dead trees). In this case the tree would be
retained, and no offset would be required; and,
o Where the minimum standard for a TPZ has not been met an offset may be required.
Removal of any habitat trees or shrubs (particularly hollow-bearing trees) should be undertaken
between February and September to avoid the breeding season for the majority of fauna species. If
any habitat trees or shrubs are proposed to be removed, this should be undertaken under the
supervision of an appropriately qualified zoologist to salvage and translocate any displaced fauna;
Construction stockpiles, machinery, roads, and other infrastructure should be wholly located in the
construction corridor, and placed away from areas supporting native vegetation, trees and/or
wetlands;
Ensure that best practice sedimentation and pollution control measures are undertaken at all times,
in accordance with Environment Protection Agency guidelines (EPA 1991; EPA 1996; Victorian Urban
Stormwater Committee 1999) to prevent offsite impacts to waterways and wetlands; and,
29Biodiversity Assessment: Mortlake South Windfarm – Underground Transmission Line
As indigenous flora provides valuable habitat for indigenous fauna, it is recommended that any
landscape plantings that are undertaken as part of the proposed works are conducted using
indigenous species sourced from a local provenance, rather than exotic deciduous trees and shrubs.

6 FURTHER REQUIREMENTS
Further requirements associated with development of the study area, as well as additional studies or reporting
that may be required, are provided below (Table 7).
Table 7. Further requirements associated with development of the study area
There is one dam located adjacent to the study area immediatelysouth of Riley Road, Terang that is considered to provide marginalhabitat for one fauna species (Growling Grass Frog) listed under theEPBC Act. However, the dam is located six metres from the edge ofthe construction corridor, with direct or indirect impacts to habitatconsidered highly unlikely to occur. As such, the action will not resultin a significant impact to Growling Grass Frog, and a referral to theCommonwealth under the EPBC Act is not required. No othermatters of NES were recorded, or are considered likely to occur.
No further action required
Flora andFaunaGuarantee Act1988
No FFG Act - listed or protected species were recorded within oradjacent to the construction corridor during the field assessments,and due to the highly modified condition of habitats, are consideredunlikely to occur. No FFG Act-list communities were recorded withinthe construction corridor. As such, a permit under the FFG Act is notrequired.
No further action required.
Planning andEnvironmentAct 1987
The study area is within Location 2, with 3.928 hectares of nativevegetation proposed to be removed. As such, the permit applicationfalls under the Detailed Assessment pathway.
The offset requirement for native vegetation removal totals 0.888General Habitat Units (HUs) across the entire alignment.
Prepare and submit a PlanningPermit application.
Wildlife Act1975
Any persons engaged to conduct salvage and translocation orgeneral handling of terrestrial fauna species must hold a currentManagement Authorisation.
Ensure wildlife specialists holda current ManagementAuthorisation.
Catchmentand LandProtection Act1994
Several weed species listed under the CaLP Act were recorded withinthe study area. To meet requirements under the CaLP Act, listednoxious weeds should be appropriately controlled throughout thestudy area.
Planning Permit conditions arelikely to include a requirementfor a Weed Management Plan.

Known resident in the study area based on site observations, database records, or expert advice; and/or,
Recent records (i.e. within five years) of the species in the local area (DELWP 2017d); and/or,
The study area contains the species’ preferred habitat.
2 Moderate Likelihood
The species is likely to visit the study area regularly (i.e. at least seasonally); and/or,
Previous records of the species in the local area (DELWP 2017d); and/or,
The study area contains some characteristics of the species’ preferred habitat.
3 Low Likelihood
The species is likely to visit the study area occasionally or opportunistically whilst en route to more suitable sites; and/or,
There are only limited or historical records of the species in the local area (i.e. more than 20 years old); and/or,
The study area contains few or no characteristics of the species’ preferred habitat.
4 Unlikely
No previous records of the species in the local area; and/or,
The species may fly over the study area when moving between areas of more suitable habitat; and/or,
Out of the species’ range; and/or,
No suitable habitat present.

requirements This report provides information that meets the following application requirements:
' The assessment pathway and reason for the assessment pathway
' A description of the native vegetation to be removed (partly met)
' Maps showing the native vegetation and property (partly met)
' Information about the impacts on rare or threatened species.
' The offset requirements determined in accordance with section 5 of the Guidelines that apply if approval is granted to
remove native vegetation.
Additional application requirements must be met including:
' Topographical and land information
' Recent dated photographs
' Details of past native vegetation removal
' An avoid and minimise statement
' A copy of any Property Vegetation Plan that applies
' A defendable space statement as applicable
