1. Introduction 1.1 Background
This Flora and Fauna Management Plan (FFMP) has been prepared by GHD Pty Ltd (GHD) for
Airservices Australia (Airservices) for the construction of a Ground-based Augmentation System
(GBAS) as part of a Global Navigation Satellite System at Melbourne Airport.
A flora and fauna assessment (GHD 2016) was undertaken which identified several ecological
values present or potentially present within the site. As the installation of the GBAS
infrastructure will cause ground disturbance, it is expected to impact upon ecological values
present within the site. This document intends to draw on information from within GHD (2016)
and best practise management principles to detail the protocol for minimising impacts to these
values.
1.2 Purpose of this plan
The purpose of this Plan is to describe how Airservices and their project contractors will manage
and control impacts on flora and fauna values from construction activities associated with the
Project.
The FFMP establishes protocols to follow for during the course of works associated with the
Project with respect to flora and fauna.
The contractors are expected to provide their own Construction Environmental Management
Plan (CEMP) which will address management of environmental values additional to flora and
fauna specific values.
1.3 Study site
The Site is located on Operations Road, adjacent to the main Airservices precinct at Melbourne
Airport (Figure 1).
The Site is currently unoccupied vacant land, with a small area used for stockpiling and
processing waste soil and building materials generated during demolition and construction
activities at the airport.
The Site is bounded by the main airport runways to the north and east. The main Airservices
precinct, with air traffic control towers is located adjacent the western boundary of the Site.
Historic and current Airport Rescue Fire Fighting (ARFF) infrastructure and training areas are
located along the northern boundary and south-west corner of the Site.
Airservices propose to install the new GBAS equipment across an area of 0.318 ha (Table 1).

1.4 Limitations
This report has been prepared by GHD for Airservices and may only be used and relied on by
Airservices for the purpose agreed between GHD and the Airservices as set out in section 1 of
this report.
GHD otherwise disclaims responsibility to any person other than Airservices arising in
connection with this report. GHD also excludes implied warranties and conditions, to the extent
legally permissible.
The services undertaken by GHD in connection with preparing this report were limited to those
specifically detailed in the report and are subject to the scope limitations set out in the report.
The opinions, conclusions and any recommendations in this report are based on conditions
encountered and information reviewed at the date of preparation of the report. GHD has no
responsibility or obligation to update this report to account for events or changes occurring
subsequent to the date that the report was prepared.
GHD has prepared this report on the basis of information provided by Airservices and others
who provided information to GHD (including Government authorities)], which GHD has not
independently verified or checked beyond the agreed scope of work. GHD does not accept
liability in connection with such unverified information, including errors and omissions in the
report which were caused by errors or omissions in that information.
The opinions, conclusions and any recommendations in this report are based on conditions
encountered, observations made and information reviewed up to the date of preparation of the
report. As GHD was only present at specific points within the relevant site(s) on specific dates
and certain time periods, this report is only indicative (and not definitive) of flora and fauna
present on the site(s). Flora and fauna (whether in type or quantity) can also change and
fluctuate at different times throughout the year (due to factors including seasonal changes,
external events or third party intervention), and it is generally not possible to observe such
changes or fluctuations where only discrete site(s) visits have taken place. GHD has no
responsibility or obligation to update this report to account for events or changes occurring
subsequent to the date that the report was prepared.
The opinions, conclusions and any recommendations in this report are based on assumptions
made by GHD and described in this report. GHD disclaims liability arising from any of the
assumptions being incorrect.
1 Note: the total area of infrastructure is greater than the total area of impact (3180 m2), as some infrastructure overlaps.

1.5 Assumptions
The following assumptions have been made when preparing this FFMP:
All construction (ground disturbance, soil laydown, vehicle movement) will be confined to
the areas detailed within Table 2.
This document will be read in conjunction with a site specific Construction Environmental
Management Plan that outlines other environmental management measures, e.g.
contaminated land, topsoil management, waste (where applicable).
Only Commonwealth listed ecological values (species and communities) are addressed
within the FFMP. Given the project is to occur on Commonwealth land, Victorian legislation
does not apply (see section 2.1).

2. Legislation 2.1 Victorian Legislation
The following items of environment legislation are usually applicable to projects in Victoria;
however, given that the project is to occur on Commonwealth land, the following legislation does
not apply:
Flora and Fauna Guarantee Act 1988
Wildlife Act 1975
Catchment and Land Protection Act 1994
Victorian Planning and Environment Act 1987
2.2 Commonwealth Legislation
The EPBC Act requires a permit for activities which may kill, injure, take, trade, keep or move a
member of a listed threatened species or ecological community, a member of a listed migratory
species, or a member of a listed marine species in or on a Commonwealth area. As ecological
values, which are listed under the EPBC Act, have been identified as present or potentially
present within the site and which may be impacted, a permit is required.
Permits will only be issued by the Commonwealth Minister for the Environment if the activity:
Contributes significantly to the conservation of the listed threatened species or ecological
community, the listed migratory species, or the listed marine species concerned, or other
listed migratory or marine species, or
The impact of the activity on a member of a listed threatened species or ecological
community, a member of a listed migratory species, or a member of a listed marine species
concerned is incidental to, and not the purpose of, the taking of the activity and:
– The taking of the activity will not adversely affect the survival or recovery in nature of
the listed threatened species or ecological community or the conservation status or
population of the listed migratory species or the listed marine species.
– The taking of the activity is not inconsistent with a recovery plan that is in force for the
listed threatened species or ecological community or a wildlife conservation plan that
is in force for the listed migratory species or the listed marine species.
– The holder of the permit will take all reasonable steps to minimise the impact of the
activity on the listed threatened species or ecological community, the listed migratory
species, or the listed marine species, or
The specified activity is of particular significance to indigenous tradition, and will not
adversely affect the survival or recovery in nature of the conservation status of the listed
threatened species or ecological community, the listed migratory species (including any
population), or the listed marine species concerned, or
The specified activity is necessary in order to control pathogens, and is conducted in a way
that will, so far as is practicable, keep to a minimum any impact on the listed threatened
species or ecological community, the listed migratory species, or the listed marine species
concerned.
A Part 13 Permit application (under section 200 of the EPBC Act) would be required to facilitate
the vegetation removal required for the works, and to allow the translocation (move) of any
Striped Legless Lizard (if found) from the works areas to the grassland directly adjacent to the
works area, which is “incidental to, and not the purpose of the action”.
GHD | Report for Airservices - Melbourne Airport Ground Based Augmentation System, 31/32991/01 | 7
The permit application would need to be accompanied by this FFMP for the purpose of
demonstrating how potential negative impacts will be minimised to species and communities
during the works.

3. Ecological values and impacts This chapter summarises the ecological values identified within the study site for which
mitigation measures will need to be implemented to protect and manage negative impacts.
Mitigation measures are outlined in Section 4.
3.1 Flora values
3.1.1 Native vegetation
The site largely comprises native grassland. One EVC, Low-rainfall Plains Grassland (EVC
132_63) was recorded during the site assessment (Figure 1). This EVC comprises treeless
vegetation mostly <1 m tall dominated by largely graminoid and herb life forms. It occupies
cracking basalt soils prone to seasonal waterlogging in areas receiving <500 mm annual
rainfall2.
At the site, Plains Grassland was relatively species-poor and dominated by the native grasses Rytidosperma spp. (Wallaby Grass), Bothriochloa macra (Red-leg Grass), Austrostipa spp.
(Spear Grass) and Chloris truncata (Windmill Grass), in association with scattered Atriplex
semibaccata (Berry Saltbush). Introduced species were prevalent and relatively dense in
patches; dominant species included Oxalis pes-caprae (Soursob), Plantago lanceolata
(Ribwort), Cynodon dactylon (Couch) and Romulea rosea (Onion Grass). Additional ephemeral
native and introduced species are also likely to emerge during spring.
3.1.2 EPBC Act listed community
One EPBC Act-listed community occurs within the study site: Natural Temperate Grassland of
the Victorian Volcanic Plain (Plate 1). This listed community corresponds to Low-rainfall Plains
Grassland (EVC 132_63).
Although the area of the listed community on site is relatively species poor, it meets the criteria for listing as Natural Temperate Grassland of the Victorian Volcanic Plain under the EPBC Act
in that:
The dominant native species represent at least 50% of the native species and the perennial
tussock cover
Non-grass weeds comprise less than 30% of ground cover (Commonwealth of Australia
2011)
It is expected that construction will result in the removal of 0.3026 ha of this community.

Plate 1 Low-rainfall Plains Grassland (EVC 132_63)
3.2 Fauna values
One type of fauna habitat is present within the study site:
Grassland (Plains Grassland (EVC 132_63))
The grassland at this site has undergone historic clearing (completely cleared in 1960s) and
disturbance (continual slashing) resulting in a decrease in quality based on the floristic
composition which is now lacking forbs and is comprised of grasses only. The grassland is
dominated by several tussock forming native grass species including Wallaby Grass, and Spear
Grass. Some embedded rock was also observed.
The extent of disturbance across the site varied and several small patches of non-native non
tussock forming grasses were present that are unlikely to be suitable habitat for anything other
than highly mobile and adaptable fauna including avifauna species such as Australian Magpie
and Willie Wagtail.
The more intact areas of grassland (Plains Grassland) have the potential to support a greater
range of species two EPBC Act listed threatened grassland species in particular:
Golden Sun Moth (GSM) (Synemon plana) (EPBC Act – Critically Endangered)
Striped Legless Lizard (SLL) (Delma impar) (EPBC Act – Vulnerable)
3.2.1 Golden Sun Moth
It is unknown if the study site supports the GSM (Plate 2, Plate 3) although the site occurs within
the “species may occur” modelled distribution mapping produced by DotE (DEWHA 2008).
There are several features of the study site and surrounds that contribute to the possibility that
the study site may support a population of this species; these are outlined within GHD 2016.
Impacts to this species may include the removal of 0.3026 ha of potentially suitable habitat,
death or injury to the subterranean larval stage of the species, and/or death or injury to adult
individuals.

Plate 2 Golden Sun Moth
Plate 3 Golden Sun Moth
3.2.2 Striped Legless Lizard
There are no actual records of SLL (Plate 4) within the study site or immediate surrounds
however the study site is within the “species known/likely to occur” modelled distribution
mapping produced by the now DotE (DEWHA 2011). There are several features of the study
site and surrounds that contribute to the possibility that the study site may support a population
of this species; these are outlined within GHD (2016).
Impacts to this species may include the removal of 0.3026 ha of potentially suitable habitat,
death, injury or the moving of individuals.

4. Onsite management objectives Project environmental objectives have been developed for general site management, flora and
fauna values, native vegetation and communities. This section describes the specific
environmental performance objectives and requirements to be achieved for the duration of the
Project. All construction works must comply with applicable legislation and conditions of permits
and approvals including this FFMP, EPBC Act permit and contractor CEMP.
4.1 Site induction
All personnel and contractors entering the site should be made aware of the FFMP which was
triggered by the expected and potential impacts of the proposed works which may result in
negative impacts to EPBC Act listed species and communities namely:
Natural Temperate Grassland of the Victorian Volcanic Plain
Golden Sun Moth
Striped Legless Lizard
All contractors and personnel are to be made aware of this FFMP and any specific requirements
detailed within “toolbox meetings”.
4.2 No-go zones
All activities including site access, laydown of plant and equipment and construction activities
(drilling, excavation, etc.) must be contained within the construction footprint delineated within
Figure 1 and specified within Table 2.
All areas of Plains Grassland (as mapped within Figure 1) that are outside the immediate
construction footprint will be delineated as no-go zones in order to:
Prevent additional loss of the EPBC Act listed community, Natural Temperate Grassland of
the Victorian Volcanic Plain
Prevent additional habitat loss for the EPBC Act listed Golden Sun Moth and the Striped
Legless Lizard
Minimise additional disturbance to individual Golden Sun Moth and Striped Legless Lizards
Vehicles and plant should not be parked on native vegetation. Parking will be located adjacent
to the site where possible, within 5 m of the RSMU or adjacent to the proposed site on the pre-
existing road. Primary parking will be situated at the main shelter. ‘No-go’ areas will be marked
out with visual aids (bunting or flagging) to let contractors know where they can or cannot go,
rather than erecting a full security fence.
The boundaries of all vegetation to be removed and vegetation to be retained must be clearly
marked on the ground and clearly communicated to contractors. This information must be
included in the site induction program.
Where a work area is within an area of Plains Grassland, as identified on the map in Figure 1,
the following activities are prohibited outside of the fenced area:
Vehicular access
Trenching or excavation including stockpiling of soil
Storage or dumping of tools, plant, machinery, equipment or waste
This information must be included in the site induction program.
12 | GHD | Report for Airservices - Melbourne Airport Ground Based Augmentation System, 31/32991/01
4.3 Weed management
The Contractor must develop a weed management strategy that includes weed prevention and
management procedures for the spread and introduction of weeds (especially Weeds of
National Significance or declared noxious weeds). Procedures shall include control of topsoil
and fill brought onto site and wash down of plant and equipment.
4.4 Topsoil management
All topsoil (top 10 cm of soil) removed during construction shall be stored nearby and covered to
avoid weeds germinating on the stockpile. Stored topsoil is to be re-used and spread over
trenches once cables have been laid. Top soil management measures should be outlined
within the contractor CEMP.
4.5 Procedures during open excavations
Excavations must be managed for ground dwelling species including the Striped Legless Lizard.
Without appropriate management, ground dwelling fauna may become trapped within
excavations (trenches, fence holes) during works. The following management actions are to be
implemented to minimise the risk of excavations to fauna:
All open excavations should be backfilled by the end of the day.
Any excavations deeper than 15 cm that cannot be backfilled at the completion of work
for that day must be completely covered to a standard that prevents Striped Legless
Lizards from entering the excavation and becoming trapped (e.g. covered with metal plate
or tarpaulin and the edges buried with soil.
Excavation will be checked each morning by the Site Manager (prior to the start of any
construction works) for the presence of any fauna that may have fallen in.
Should any fauna be found then they will be processed as per section 4.6.
4.6 Fauna encountered on site
An EPBC Act permit is required to kill, injure, take, trade, keep or move a member of a listed
threatened species. Named species likely to be found within the study site are the Striped
Legless Lizard and the Golden Sun Moth. Only an appropriately trained ecologist named on the
EPBC Act permit (from here in called project ecologist) shall be permitted to handle any listed
species found.
Should an animal be observed in the vicinity of the works, then the following procedure should
be followed:
1. Contact the site supervisor.
2. The site supervisor shall determine if the animal is at risk of being harmed.
a. If yes, all works in the vicinity of the animal (works in other areas may continue)
should be halted and the project ecologist contacted to conduct a “catch and release”
in order to safely remove the animal from risk (see section 4.7)
b. If the animal is not at risk of being harmed and can move on of its own accord, then
works should be halted in the vicinity of the animal until it moves on (works may
continue in other areas of the site). If the animal is not capable of moving on of its own
accord, then the following steps should ensue.
3. The site supervisor shall inspect the animal to determine if it is a Golden Sun Moth or a
Striped Legless Lizard.
GHD | Report for Airservices - Melbourne Airport Ground Based Augmentation System, 31/32991/01 | 13
4. If the site supervisor cannot identify the animal, then the project ecologist will be
contacted to identify the animal. This may be done via photographs emailed to the project
ecologist.
5. If the animal is believed to be a Golden Sun Moth or Striped Legless Lizard proceed to
point 6. If the animal is not one of these species, proceed to point 7.
6. The site supervisor shall contact the named ecologist to come to the site. The following
steps will then occur:
a. The named ecologist will confirm the species identification and photograph it for
reference.
b. The animal will then be relocated as per section 4.7.
c. If the animal is injured then procedures outlined within section 4.8 will be followed.
The Site Manager will contact the named ecologist for direction.
1. A record will be kept of any released individuals, detailing species, condition, life stage,
discovery location and release location. This record will be provided to the Victorian
Biodiversity Atlas.
4.7 Relocation of fauna
Any fauna that require relocation shall be relocated using the appropriate animal hygiene
(section 4.7.1) to the nearest area of suitable habitat outside of the study site. If the animal in
question is a Golden Sun Moth or Striped Legless Lizard, then it may only be relocated by a
project ecologist. For any other fauna that requires relocation the project ecologist shall be
contacted for advice.
Appropriate habitat for grassland fauna occurs immediately adjacent to the site and should be
used for all relocations.
4.7.1 Animal hygiene
Appropriate hygiene measures for handling animals should be employed at all times to prevent
the spread of disease and pathogens. The following measures as a minimum should be
employed:
Wash hands between the handling of different animals
Use disposable and pre rinsed vinyl gloves to handle any frogs (Gloves are to be single
use)
Immediately after capture animals should be bagged in an appropriately sized calico bag (or
plastic zip for frogs) (bags are to be single use only and should only contain one animal)
If possible, capture Golden Sun Moths with a butterfly net to avoid handling
4.8 Procedures for injured wildlife
If an animal is found within the study site that is injured the named ecologist should be
contacted to determine the best course of action for the individual.
If the injuries are too great for the animal to be relocated, then the animal should be taken to a
Wildlife Carer or Veterinary Clinic.
14 | GHD | Report for Airservices - Melbourne Airport Ground Based Augmentation System, 31/32991/01
If the injured animal is a Striped Legless Lizard, then the named ecologist will be required take
the animal to the appropriate care facility:
The Maribyrnong Veterinary Clinic is listed as dealing with a range of fauna groups
including reptiles and can be contacted on 03 9317 4432. The clinic is located at 95A
Rosamond Road, Maidstone, 3012
Wildlife Victoria can be contacted on 1300 094 535 and will respond to all sick, injured or
orphaned native wildlife queries
DotE may need to be notified pending any EPBC Act permit conditions.
4.9 Site reinstatement and rehabilitation
Areas available for reinstatement include all areas that are only temporarily disturbed (e.g.
trenches) that will not house permanent infrastructure. This includes all the cable lengths. Cable
lengths in all instances are no greater than 0.4 m wide. These areas are to be revegetated
using a locally indigenous grassland (i.e. EVC 132) seed mix. Suitable grassland species
include the following:
Bothriochloa macra (Red-leg Grass)
Chloris truncata (Windmill Grass)
Rytidosperma caespitosum (Common Wallaby-grass)
Themeda triandra (Kangaroo Grass)
For revegetating at the conclusion of works, grass seed must be hydro-seeded to minimise bird
attraction.
4.10 Reporting and documentation
The following information should be documented throughout the course of the construction:
All animals that are captured at the study site (including species, condition of animal and
management action undertaken).
All animals that are relocated from the study site (including species, location where animal
was found, location of where animal was relocated, condition of animal).
All animals that are injured as a result of construction activities (including species, location
of capture, cause of injury – if known, management action undertaken, result of action, e.g.
animal condition).
This information may need to be provided to DotE pending any EPBC Act permit conditions.
