Summary

Biosis Pty Ltd was commissioned by Transport for NSW (TfNSW) to undertake a terrestrial flora and fauna

assessment of Oatley Station, Oatley. TfNSW is currently implementing the Transport Access Programme

which aims to improve the accessibility of existing stations across the network. A Review of Environmental

Factors (REF) is to be submitted to assess potential impacts on the environment, as part of the approval

process under Part 5 of the Environmental Planning and Assessment Act 1979 (EP&A Act). This report forms the

terrestrial flora and fauna component of the REF.

Ecological values

Key ecological values identified within the study area include:

0.19 ha of highly constrained Degraded hinterland sandstone gully forest. No removal of this

vegetation community is proposed.

0.06 ha of moderately constrained Modified eucalypt woodland of which removal of 0.04 ha is

proposed.

Three hollow bearing trees (HBT), including two Sydney Red Gums Angophora costata and one

Spotted Gum Corymbia maculata (to be removed) that may provide suitable roosting habitat for the

threatened Eastern Freetail-bat.

Habitat trees that may provide suitable foraging habitat and resources for threatened avifauna

species and flying-foxes.

Five flora species listed as noxious within the Hurstville and Kogarah Local Government Area (LGA).

Recommendations

The principal means to reduce impacts on biodiversity values within the study area will be to avoid and

minimise removal of native vegetation and habitat.

Through development of the concept options report and implementation of the recommendations, the

current reference design is relatively sympathetic to the ecological constraints within the study area.

Recommendations to minimise impacts on biodiversity include Tree Protection Zones, implementing hygiene

protocols and appropriately locating construction compounds. These, along with other recommendations,

are further outlined in Section 4.2.

Conclusions

The overall impact of the proposed upgrade of Oatley station to native flora and fauna is considered to be

low. It is unlikely that the proposed works will result in a significant impact to threatened species, populations

or communities and additional approvals are not required.

1. Introduction

1.1 Project background

Biosis Pty Ltd was commissioned by Transport for NSW (TfNSW) to undertake a terrestrial flora and

fauna assessment of Oatley Station, Oatley. As a part of the Transport Access Programme, currently

being rolled out across the network, TfNSW is proposing a number of upgrades to the existing

infrastructure of Oatley Station, including an aerial overbridge stairs, lift and entrance forecourt,

extension of commuter carparking and commuter drop-off areas. A Review of Environmental Factors

(REF) is to be submitted as part of the approval process under Part 5 of the Environmental Planning

and Assessment Act 1979 (EP&A Act). This report forms the terrestrial flora and fauna component of

the REF.

A constraints assessment has previously been completed (GHD, 2012) and informed the

development of the current design. It was noted that only a Reference Design is currently available

which may be subject to change; therefore this report covers an area more extensive that the

proposed construction footprint.

1.2 Scope of assessment

The objectives of this investigation are to:

Undertake database searches to determine the potential for NSW or Commonwealth

threatened biota to occur within the study area.

Describe the vascular flora (ferns, conifers, flowering plants) and vertebrate fauna (birds,

mammals, reptiles, frogs, fish).Map native vegetation and other habitat features.

Confirm the extent and condition of any Threatened Ecological Communities (TEC).

Confirm tree species along the western embankment that are proposed for removal.

Confirm tree species along the eastern side of Oatley station that are proposed for removal.

Confirmation of tree species within the commuter carpark that are proposed for removal.

Undertake searching for threatened flora species.

Undertake searching for evidence of occupation by threatened fauna, particularly the

Powerful Owl and Grey-headed Flying-fox.

Review the implications of relevant biodiversity legislation and policy.

Identify potential implications of the proposed development and provide recommendations

to assist with development design.

Recommend any further assessments of the site that may be required.

1.3 Location of the study area

The study area is located in Oatley, approximately 18 kilometres south of the Sydney Central

Business District (CBD), north of the Georges River, and is part of the St George area (Figure 1). The

study area is defined as the area of potential direct impact of the proposed works, and includes


proposed infrastructure upgrades to the car park on Oatley Parade, and the construction of a

pedestrian ramp to be accessed from Oatley Parade to Mulga Road (located adjacent to River Road).

It encompasses 1.54 ha of private and public land and adjacent road reserves and is currently zoned

RE1 Public Recreation, SP2 Infrastructure (Railway) and R2 Low Density Residential.

2. Methods

2.1 Nomenclature

The flora taxonomy (classification) used in this report follows the most recent Flora of NSW (Harden,

2002). Where nomenclature was uncertain, species names were verified with the on-line Australian

Plant Name Index (Australian National Botanic Gardens, 2007). In the text of this report, flora species

are referred to by both their common and scientific names when first mentioned and common

names only thereafter. Flora common names, where available, have been included in threatened

species tables and the complete flora list in Appendix 1.

Names of vertebrates follow the Census of Australian Vertebrates maintained by the Commonwealth

Department of Environment (DEWHA 2009). In the body of this report vertebrates are referred to by

both their common and scientific names when first mentioned. Subsequent references to these

species cite the common name only. Common and scientific names are included in the fauna list in

Appendix 2.

2.2 Literature and database review

In order to provide a context for the study area, information about flora and fauna from within five

kilometres of the study area (the ‘local area’) was obtained from relevant public databases. Records

from the databases outlined in Table 1 were collated and reviewed.

2.3 Site investigation

2.3.1 Flora assessment

The flora assessment was undertaken on 15 January 2014 by Ed Cooper (Botanist) with Biosis, who

assessed the vegetation communities of the study area using a combination of random meander

(Cropper, 2003) and vegetation association to determine the vegetation assemblage and the relevant

classification, present within the study area.

A list of flora species was compiled (Appendix 1). The general condition, structure and connectivity of

native vegetation was observed, as well as the effects of current seasonal conditions. Notes were

made on specific issues such as noxious weeds, evidence of management works and general

impacts.

Flora records will be submitted to OEH for incorporation into the Atlas of NSW Wildlife.

2.3.2 Fauna assessment

The fauna assessment was undertaken on 15 January 2014 by Alexandra Cave (Zoologist) with Biosis,

to determine its values for fauna. These were determined primarily on the basis of the types and

qualities of habitat(s) present. All species of fauna observed during the assessment were noted

(Appendix 2) and active searching for fauna was undertaken. This included direct observation,

searching under rocks and logs, examination of tracks and scats and identifying calls. Particular

attention was given to searching for significant species and their habitats, particularly those outlined

in Section 1.2. Fauna species were recorded with a view to characterising the values of the site and

the investigation was not intended to provide a comprehensive survey of all fauna that has potential

to utilise the study area over time.


Fauna records will be submitted to OEH for incorporation into the Atlas of NSW Wildlife.

2.3.3 Permits and Licenses

The flora and fauna assessment was conducted under the terms of Basis's Scientific License issued

by OEH under the NP&W Act (SL100758). Fauna survey was conducted under approval 11/355 from

the NSW Animal Care and Ethics Committee.

2.4 Survey limitations

Ecological surveys provide a sampling of flora and fauna at a given time and season. There are a

number of reasons why not all species will be detected at a site during survey, such as species

dormancy and migration and breeding behaviours of some fauna. In many cases these factors do

not present a significant limitation to assessing the overall biodiversity values of a site and potential

habitat for such species was assess during the site investigation.

The current flora and fauna assessment was conducted in mid summer which is not an optimal time

to survey for all species, particularly for some cryptic flora species such as Orchids which have a finite

flowering time.

The tree hollow survey was undertaken from the ground using binoculars to determine the presence

of tree hollows. Where there was uncertainty as to whether hollows had depth these would have

been described as potential tree hollows.

2.5 Legislation and policy

The implications for the project were assessed in relation to key biodiversity legislation and policy

including;

Environment Protection and Biodiversity Conservation Act, 1999 (EPBC Act);

Environmental Planning and Assessment Act, 1979 (EP&A Act), including

– State Environmental Planning Policy No. 19 – Bushland in Urban Areas.

Threatened Species Conservation Act, 1995 (TSC Act).

Native Vegetation Act, 2003 (NV Act).

Noxious Weeds Act, 1993 (NW Act).

National Parks and Wildlife Act, 1974 (NP&W Act).

Kogarah and Hurstville Development Control Plan (DCP), 2002.

Kogarah and Hurstville (Draft) Local Environment Plan (LEP), 2012.

2.6 Mapping

Mapping was conducted using hand-held (uncorrected) GPS units (Garmin GPS Map 62s) and aerial

photo interpretation. The accuracy of this mapping is therefore subject to the accuracy of the GPS

units (generally ± seven metres) and dependent on the limitations of aerial photo rectification and

registration.


Mapping has been produced using a Geographic Information System (GIS). Electronic GIS files which

contain our flora and fauna spatial data are available to incorporate into design concept plans.

However this mapping may not be sufficiently precise for detailed design purposes.


3. Results

3.1 Ecological Results

The ecological features of the study area are described below and mapped in Figure 2.

A total of 81 flora species (16 native and 65 exotic) as well as eight fauna species were recorded

during the current assessment. Species recorded during the flora and fauna assessment are listed in

Appendix 1 (flora) and Appendix 2 (fauna). Unless of particular note, these species are not discussed

further.

A list of significant species recorded or predicted to occur in the local area is also provided in those

appendices, along with an assessment of the likelihood of the species occurring within the study

area.

3.2 Site context and connectivity

The study area is located in the suburb of Oatley. Oatley is predominately a residential suburb, with

a number of natural bush areas and remnant trees in gardens and along streets. Of particular note

to this project is Myles Dunphy Reserve, which is located to the south-west of the station. Myles

Dunphy Reserve forms a large patch of remnant native vegetation in good condition, and is known to

support a number of threatened flora and fauna species and threatened ecological communities.

The proposed project footprint is located either side of the rail corridor along the entirety of the

Oatley Station platform. Within the development footprint, much of the remnant native vegetation

has been removed or altered with remaining native vegetation in a patchy and highly fragmented

state.

These modified vegetation communities would support opportunistic and resilient native fauna,

often associated with urban habitats. This is further supported by the fauna documented through

observations made during the site visit (refer to Table 14). Due to the presence of the rail corridor,

Mulga Road and Oatley Parade connectivity is almost non-existent other than for mobile avifauna

species.

3.3 Vegetation and fauna habitat

The vegetation and fauna habitat throughout the majority of the study area has been modified by

changes in land use throughout the local area. Remnant vegetation has predominantly been cleared

to make way for residential, commercial, recreational and infrastructure development. Such

development includes the commuter carpark, Oatley Memorial Park, the rail corridor and the

ornamental garden on the corner of Oatley Parade and River Road.

The study area supports four separate vegetation communities based on condition and floristic

composition, including two native vegetation communities and two exotic vegetation communities,

including:

Degraded hinterland sandstone gully forest (native).

Mown exotic grasses and ornamental plantings (exotic).

Modified eucalypt woodland (native).


Exotic closed woodland (exotic).

The floristic composition, associated soil type and location of each community is detailed in Table 2

to Table 5, and outlined in Figure 2.

Topography, geology and soils

This community is typically associated with the

lower slopes of dry sandstone gullies receiving

800 – 1300 mm of rain per annum (Tozer et. al.

2010). The study area is located in a transitional

area between Lucas Heights and the

predominantly sandstone based Gymea soil

landscapes (Chapman and Murphy, 1989). The

Lucas Heights soil landscape is transitional in

it's own right with both shale and sandstone

influences. The soil profiles across the study

area are likely to have been altered by historic

vegetation removal, development and

introduction of topsoil and organic matter.

Condition and weed occurrence

The degraded hinterland sandstone gully

forest within the study area was present in the

form of scattered remnant trees, confined to

the southern boundary of Boondarra Reserve.

Mature Blackbutt Eucalyptus pilularis, Narrow-

leaved Scribbly Gum Eucalyptus racemosa and a

single Sydney Red Gum Angophora costata

formed the canopy. The midstorey was limited

to scattered Cheese Tree Glochidion ferdinandi

with a groundstorey of mown exotic grasses

Fauna habitat features

The degraded hinterland sandstone gully forest

vegetation type within the study area consists

of a handful of remnant habitat trees, including

mature Blackbutt and Narrow-leaved Scribbly

Gum. During flowering periods these tree

species may provide some level of suitable

foraging resources for threatened species, such

as Cockatoos (i.e. Gang-gang Cockatoo

Callocephalon fimbriatum, Glossy Black-

cockatoo Calyptorhynchus lathami and Major

Mitchell's Cockatoo Lophochroa leadbeateri):

however it is considered somewhat unlikely

due to the limited extent of suitable habitat

and proximity of this area to the railway (<

20m) and urban nature of the surrounds.

These feed trees may also provide some

limited foraging resources for the Grey-headed

flying-fox (GHFF) Pteropus poliocephalus,

particularly given there is a known GHFF

population in the adjoining reserve. Scattered

Cheese Trees, where Rainbow lorikeets

Trichoglossus haematodus were observed

foraging on new foliage and fruit, may also

provide potential foraging habitat for

threatened species such as the Little Lorikeet

Glossopsitta pusilla. However, given the

availability of significant areas of larger, better

quality habitat in the locality, the significance of

the scattered habitat resources in this area is

considered to be low. Even so, the trees in this

area are not anticipated to be impacted by the

proposed works. This area also supports an

abundance of coarse woody debris (CWD)

deposits, with old railway sleeper stacks,

littered cement and metal fragments,

surrounded by a thick leaf litter dense with

Casuarina needles.

Conservation Status

Commonwealth EPBC Act: Not listed

NSW TSC Act: Not listed

Based on the lack of key indicator species

within the midstorey, shrubstorey and

groundstorey, this community was not

considered to represent the TSC Act listed EEC

Southern Sydney sheltered forest on transitional

sandstone soils in the Sydney Basin Bioregion.

Recreational areas, and associated disturbed

soils, contained mown exotic grasses and

are likely to be typical of the transitional area

between Lucas Heights and Gymea soil

landscapes (Chapman and Murphy, 1989),

however the topsoils have been modified by

historic; vegetation removal and introduction

of topsoil and organic matter.


This community was comprised almost

exclusively of exotic species. The canopy was

sparse, but included Brush Box Lophostemon

confertus, Monterey Cypress Cupressus

macrocarpa and Jacaranda Jacaranda

mimosifolia. Pepper Tree Schinus areira are

common throughout the recreational areas

along with scattered Cocos Palm Syagrus

Catsear. The high proportion of exotic species

and maintained nature of this community

means that is of little botanical value.

particular, provide good quality habitat trees

for microbats - with large deposits of

exfoliating bark, sections of dead wood and

protruding stags and some small spouts and

hollows providing multiple potential entry

3.4 Threatened flora, fauna and ecological communities

3.4.1 Threatened species

No EPBC Act or TSC Act listed threatened flora or fauna species were identified within the study area

during the assessment conducted by Biosis on 15 January 2014.

Threatened species recorded or predicted to occur within five kilometres of the study area are listed

in Appendix 1 (flora) and Appendix 2 (fauna) and mapped in Figure 3 (flora) and Figure 4 (fauna). An

assessment of the likelihood of these species occurring in the study area, and an indication of which

habitats or habitat features are likely to support the species is included.

Listed marine and shorebird species that were identified as having the potential to occur are listed in

Table 16. These species are not considered in further detail in this report given the complete absence

of suitable habitat in the study area for these species. A summary of those species recorded or with a

medium or higher likelihood of occurring in the study area is provided in Table 6.

Table 6: Summary of threatened species likely to occur in proximity to the study area

Name Area of value within the study area

Threatened ecological communities – no threatened ecological communities were recorded or

considered likely to occur within the study area.

Threatened flora – no threatened flora was recorded or considered likely to occur within the

study area.

Threatened fauna – one threatened fauna species was considered to have a medium potential

of being impacted by the proposed works

Eastern Freetail-bat

Mormopterus norfolcencis

The species is considered to have the potential to utilize

foraging and roosting habitat resources in the study area,

and suitable microbat hollows were observed in a number

of trees surrounding the carpark, including two Sydney Red

Gums, and one Spotted Gum. The removal of these trees

has the potential to impact breeding resources for this

species in the locality, if they were found to be utilising the

HBTs on site.

3.4.2 Threatened ecological communities

Background research prior to the site investigation identified that three vegetation communities

were mapped in or adjacent to the study area (Tozer et al. 2010). An analysis of whether these

vegetation communities are representative of threatened ecological communities listed under the

EPBC Act or TSC Act and their occurrence within the study area is provided in Table 7.

Table 7: An analysis of vegetation communities mapped in the study area by Tozer (et al.

2010) are representative of TECs

al. 2010) is not considered to be representative of

any TECs.

This vegetation community was not mapped in

the study area.

Hinterland sandstone gully forest Hinterland sandstone gully forest (Tozer et al.

2010) is not considered to be representative of

any TECs.

Overstorey species in a patch of degraded

hinterland sandstone gully forest mapped in the

southeast of the study area, including remnant

Blackbutt, Narrow-leaved Scribbly Gum, Sydney

Red Gum and Cheese Tree, are diagnostic

overstorey species for Southern Sydney

Sheltered Forest TEC.

However, based on the lack of key diagnostic

species in the groundstorey and midstorey this

vegetation community was not considered

representative of Southern Sydney Sheltered

Forest TEC.

Sydney turpentine ironbark forest Sydney turpentine ironbark forest (Tozer et al.

2010) is listed as a threatened ecological

community (TEC) under both the TSC Act

(Endangered) and the EPBC Act (Critically

endangered).

A focus of the site visit was to determine whether

the patches previously mapped as a TEC, or any

other vegetation, was consistent with the final

determinations for Sydney turpentine ironbark

forest (NSW Scientific Committee, 2011). The

small patch of Sydney turpentine ironbark forest

mapped by Tozer (et al. 2010) does not contain

key diagnostic species and is not considered

representative of the Sydney turpentine ironbark

forest TEC.

Myles Dunphy Reserve, located approximately 80

m southwest of the study area, is comprised of

remnant bushland and wetlands and contains a

relatively large patch of Sydney turpentine

ironbark forest TEC.

3.5 Noxious weeds

Five species listed as noxious within Hurstville and Kogarah City Council LGAs were recorded within

the study area (DPI, 2013). The details of these species, along with the legal requirements, are

outlined in Table 8below.

4. Potential impacts and recommended mitigation measures

This section identifies the potential impacts of the proposed Oatley station upgrade on the ecological values

of the subject site and study area (Section 4.1) and includes recommendations to assist TfNSW to avoid and

minimise the impacts on biodiversity values (Section 4.2). The proposed upgrades to Oatley stations are

outlined in Section 1 and shown in Figure 5.

4.1 Potential impacts

4.1.1 Direct impacts

The direct impact zone is defined as the construction footprint, forming a corridor from the bus shelter on

Oatley Parade west to Mulga Street in addition to the commuter carpark on Oatley Parade (Figure 5).

The proposed alignment of the bridge and lift infrastructure will require 0.06 ha of vegetation clearing,

including:

0.01 ha of Mown Exotic Grasses and Ornamental Plantings

0.04 ha of Modified Eucalypt Woodland.

0.01 ha of Exotic Closed Woodland.

The proposed works are likely to result in the removal of 24 trees, as outlined in Table 18 (Appendix 3) and

shown in Figure 6. Of these, 12 are native species. A further 14 trees have a moderate likelihood of impact

due to their proximity to the proposed works. Of these nine are native species. The extension of the

commuter carpark is likely to require the clearing of the Sydney Red Gum and Pepper tree in the centre and

potentially the row of Spotted Gum and Tallowwood and the mature Sydney Red Gum in the northern corner.

The current scope of the project does not include the removal of any mature vegetation from within the

Degraded hinterland sandstone gully forest community. Although not considered to represent a TEC, these

trees are of ecological value and recommendations regarding their protection have been made in Section 4.2.

4.1.2 Indirect impacts

The indirect impact zones are the areas where impacts are likely to be temporary and restricted to the

construction phase of the upgrade.

Indirect impacts are likely to be greatest in close proximity to the subject site, however the proposal has the

potential to have indirect impacts at greater distance particularly where stockpiling or equipment storage is

required. Potential indirect impacts to vegetation include the following:

Damage to remnant native trees during movement of soil by machinery across the site.

Damage to native vegetation resulting from machinery and soil compaction.

Introduction of noxious weed species or spread of those currently occurring within the study area

construction plant and equipment.

The introduction of soil pathogens.

Soil contamination resulting from fuel spills or other contamination.


As only a Reference Design is currently available which may be subject to change, the indirect impact zone is

considered to include the entirety of the study area (less direct impacts), totaling approximately 1.5 ha of

largely landscaped exotic vegetation, including:

0.19 ha of Degraded hinterland sandstone gully forest

0.02 ha of Modified eucalypt woodland

1.06 ha of Mown exotic grasses and ornamental plantings

0.23 ha of Exotic closed woodland

In addition to the impacts outlined above, various compound areas will be required for the storage of

equipment and infrastructure. The location of these compound areas is yet to be confirmed; however

potential areas within the study area have been identified and categorised based on their ecological values

(Figure 5). The grading system is as follows;

Category 1 – Ideal.

– Includes areas of hard standing with no ecological value.

Category 2 – Preferred.

– Includes mown exotic grasses that will recover quickly from disturbance. The Category 2

patch to the east of Oatley Parade is comprised of the mown areas surrounding remnant

trees.

Category 3 – Possible.

– Includes landscaped vegetation with relatively little ecological value. Category 3 areas should

only be used where no viable alternative Category 1 or 2 sites are available.

Category 4 – No Go Zones.

– Includes mature native and exotic canopy species that should be avoided.

Amelioration measures to minimise the potential for indirect impacts on the vegetation to be retained are

discussed in Section 6.

4.1.3 Impacts to threatened flora and ecological communities

No TSC act or EPBC Act listed TECs were recorded within the study area.

No threatened flora species were identified during the site assessment or are considered likely to occur

within the study area, and therefore no direct or indirect impacts are anticipated.

There is potential for removal of a number of trees surrounding the carpark, including two Sydney Red Gums,

and one Spotted Gum, to impact on roosting and breeding resources for the Eastern Freetail-bat

4.1.4 Impacts to fauna habitat

The proposed railway station upgrade will cause some localised disturbance to potential fauna habitat

associated with the railway corridor, including:

Three hollow-bearing trees which provide some scattered seasonal potential foraging habitat for

various avifauna species, such as the Grey-headed flying-fox, and multiple small hollows, stags,

spouts and fissures (refer to Plate 2) that provide potential roosting resources for microbats

including the Eastern Freetail-bat.

Foraging resources, such as the Cheese Trees, which may support a variety of frugivorous birds.


Injury or death of resident or visiting fauna may result during the clearing of vegetation, and activities related

to the removal of habitat trees. Some species can more readily evade injury by flying (birds). Many species,

however, are unlikely to move quickly enough to avoid being injured. For example, many smaller ground-

dwelling species, such as frogs, lizards and snakes, are unable to move rapidly and have little space to find

refuge within the study area.

Plate 1: Sydney Red Gum HBT showing spouts, fissures and associated stags

4.1.5 Habitat fragmentation and increased edge effects

Habitat fragmentation is the division of a single area of habitat into two or more smaller areas, with a new

habitat type occurring in the area between the fragments. This new dividing habitat type is often artificial and

inhospitable to the fauna species remaining within the fragments and can provide suitable conditions for

weed species to establish, which may out-compete native flora species.

The vegetation communities within the subject site are currently highly fragmented and edge affected,

showing a high proportion of exotic species. The Proposal is unlikely to further increase fragmentation or

edge effects on these communities since the patch sizes are small and have evidence of disturbance

throughout.

As the site is highly urbanized it is unlikely that the Proposal will create or extend any barriers to movement

for flora and fauna.

4.1.6 Impacts on embankment stability

The western rail embankment appears to be constructed from a combination of railway sleepers, ballast and

fill. A number of star picket's are protruding from the embankment at precarious angles suggesting that the

current level of stability is poor.

Mature trees and shrubs will require removal from the western rail embankment to facilitate construction of

the over bridge. The extent to which the embankment is being stabilised by this vegetation is unclear;

however a precautionary approach should be adopted to minimize the risk of slipping or collapse during

vegetation removal.


4.2 Recommended mitigation measures

The principal mechanism to reduce impacts on biodiversity values within the study area will be to minimise

removal of native vegetation and fauna habitat by restricting the encroachment of the works on adjacent

native vegetation.

The principal means to reduce impacts on biodiversity values within the study area will be to avoid and

minimise removal of native vegetation and habitat.

The Oatley Station Precinct Ecological Constraints Assessment (GHD, 2012) outlined the key constraints of the

study area as the mapped area of Degraded hinterland sandstone gully forest (Figure 2), mapped as very

highly constrained, and the Modified eucalypt woodland (Figure 2) mapped as moderately constrained.

Having determined that the Degraded hinterland sandstone gully forest within the study area is not

consistent with the TSC Act listed TEC Southern Sydney sheltered forest, this vegetation is considered to be

moderately constrained.

The majority of the study area was determined to be of relatively low biodiversity value because of historic

disturbance which has lead to broad scale clearing of native vegetation and substantial recruitment of exotic

species. It would appear that the results of the constraints assessment have been taken into consideration

when deciding upon the alignment of the reference design, which is sympathetic with the biodiversity values

which are present.

The following mitigation measures would be implemented to avoid and minimise potential impacts to

ecological values during and after the construction phase of the proposed upgrade:

Existing native vegetation would be retained where possible.

Tree protection zones, including root protection zones and canopy protection zones, should be

established around remnant in accordance with AS 4970 – 2009. An approximate alignment for

fencing for the Degraded hinterland sandstone gully forest remnant trees is marked in Figure 6.

Additional fencing may be required for remnant trees to the east of Oatley Parade once the final

location of construction compounds is determined.

Construction staff would be inducted to an appropriate level and made aware of the importance of

the remnant trees within the Degraded hinterland sandstone gully forest.

The vegetation within the Exotic closed woodland community of the subject site is of relatively low

ecological value; however it is currently stabilising the western railway embankment. The current

extent of this stabilisation is unknown, therefore its removal should be carried out in a precautionary

manner. Where possible, stumps would be left in situ and poisoned with an appropriate herbicide to

prevent regrowth. If complete removal of trees providing substantial stabilisation is required, addition

advice regarding engineering works may need to be sought.

Construction compounds should be located in the lowest category area that is viable. Where Category

1 areas are not available, areas of native vegetation should be rehabilitated following construction

activities. The removal of native or mature canopy species for compound purposes should be

avoided.

Prevent the dispersal of weed seed or soil born pathogens into native vegetation through the

implementation of vegetation hygiene protocols for footwear, vehicles, heavy plant and machinery.

Be aware of nesting fauna within shrubby vegetation. Avoid permanent removal of these occupied

habitats wherever possible. Where vegetation removal/maintenance must take place, wait until the

nesting fauna have moved on.


Appropriately designed sediment and erosion controls should be installed and maintained during

excavation works to prevent any potential sediment runoff entering Myles Dunphy Reserve.

There is potential to improve the quality of the Exotic closed woodland community either side of the

overbridge alignment by engaging a bush regeneration contractor to remove exotic species,

particularly noxious weeds from this area, and revegetate these areas with endemic native species.

On the eastern side of the station:

– The potential for a “green wall” to the forecourt to soften any areas of blank stair wall would

be investigated. Proposed species would be a combination of natives and introduced

species selected to complement the existing vegetation within the Douglas Cross Gardens.

– A terraced rock garden bed would be provided to capture the change of grade between the

forecourt and Douglas Cross Gardens

On the western side of the station:

– Existing vegetation would be retained where possible.

– The disturbed embankments would be re-vegetated. Advanced trees would be planted to

filter views, provide a gateway to the station overpass entrance and reduce the scale of the

proposed overpass.

In the commuter car park:

– Existing vegetation would be retained and protected where possible.

– To soften hard treatments, low planting would be introduced.

Generally, new vegetation will be used to replace vegetation removed, in line with Transport Projects Division

(TPD) Vegetation Offset Guide. Plants species used in revegetation for the Proposal would be based on a

number of guiding documents and existing site plant species. Native and endemic species would be used

where appropriate. There would be compliance with appropriate standards for soils, mulches etc.

Details of the trees to be removed, along with the likelihood or removal, is outlined in Appendix 3. The

likelihood of removal has been determined based on the drawings provided to Biosis and are therefore mays

be subject to change. Based on the small size and lack of community structure of the patch of trees to be

removed, it is considered appropriate to use the TfNSW Single tree offsets (TfNSW, 2013) calculator to

determine the offset requirement for this proposal. Based on the TAP-1822-AR-0006 drawing, it has been

determined that three large trees (DBH >60 centimetres) and 21 medium trees (DBH 15 to 60 centimetres)

will require removal. In accordance with the Single tree offsets calculator, a minimum of 112 trees should be

planted to compensate the vegetation to be cleared. Based on trees present within native vegetation

communities on-site it is recommended a mix of Spotted Gum, Sydney Red Gum, Tallowood and Turpentine

are used.

5. 4. Biodiversity Legislation and Government Policy

This section provides an assessment of the project against key biodiversity legislation and government policy.

Where available, links to further information are provided. This section does not describe the legislation and

policy in detail and guidance provided here does not constitute legal advice.

5.1 Commonwealth

5.1.1 Environment Protection and Biodiversity Conservation Act, 1999

The EPBC Act applies to developments and associated activities that have the potential to significantly impact

on Matters of National Environmental Significance (NES) protected under the Act.

Link for further information including a guide to the referral process is available at:

http://www.environment.gov.au/epbc/index.html

Matters of NES relevant to the project are summarised in Table 9. It includes an assessment against the EPBC

Act policy statements published by the Australian Government which provide guidance on the practical

application of EPBC Act including.

Table 9: Assessment of the project against the EPBC Act

Matter of NES Project specifics Assessment against Guidelines

Threatened

species and

ecological

communities

59 fauna and 24 flora species have been

recorded or predicted to occur in the

project search area. The likelihood of these

species occurring in the study area is

assessed in Appendix 1 (flora) and

Appendix 2 (fauna).

None of these species are likely to occur

and the proposed upgrade is unlikely to

constitute a significant impact.

Migratory

species

35 migratory species have been recorded

or predicted to occur in the locality.

While some of these species would be

expected to use the study area on

occasions, and some of them may do so

regularly or may be resident, it is not

considered to provide important habitat

for an ecologically significant proportion of

any of these species.

On the basis of criteria outlined in the relevant Significant Impact Guidelines it is considered unlikely that a

significant impact on a Matter of National Environmental Significance would result from the proposed action.

A referral to the Australian Government Minister for the Environment to determine whether the action

requires approval under the EPBC Act is not required.

http://www.environment.gov.au/epbc/index.html


5.2 State

5.2.1 Threatened Species Conservation Act, 1995

The TSC Act provides for the protection and conservation of biodiversity in NSW through the listing of

threatened species, populations and communities; key threatening processes; and critical habitat for

threatened species, populations and communities.

Native vegetation within the study area is not a listed community; however contains threatened flora or fauna

species, or habitat for them. Impacts to threatened species, populations and communities must be assessed

through the Assessment of Significance (formerly known as the “7-part test”) process under Section 5A of the

EP&A Act (refer to Section 5.2.2 below).

Habitat critical to the survival of an endangered or critically endangered species, population or ecological

community can be identified under the TSC Act and listed on the Register of Critical Habitat kept by the OEH.

The study area does not contain declared ‘critical habitat’.

A licence to harm/pick/damage habitat of a threatened species, population or community or damage critical

habitat is / is not required.

Key threatening processes, defined as a process that threatens, or could threaten, the survival or evolutionary

development of species, populations or ecological communities, are identified under the TSC Act and

considered during the Assessment of Significance. The proposed upgrade has the potential to constitute or

exacerbate KTPs outlined in Table 10.

Table 10: Key threatening processes listed under the TSC Act, likely to be constituted or

exacerbated by the proposed upgrade

Key threatening process Activity like to constitute or exacerbate the KTP

Clearing of native vegetation The proposal will result in the clearing of individual

remnant trees and shrubs in the modified eucalypt

woodland communities and exotic closed woodland

community.

Infection of native plants by Phytophthora

cinnamomi

No Phytophthora was identified during the site

assessment, however the introduction of personnel

and construction equipment to the subject site has

the potential to establish it.

Introduction and Establishment of Exotic Rust

Fungi of the order Pucciniales pathogenic on

plants of the family Myrtacea

No exotic rust fungi was identified during the site

survey, however the introduction of personnel and

construction equipment to the subject site has the

potential to establish it.

Invasion and establishment of exotic vines and

scramblers

Exotic vines and scramblers including Moth Vine,

Morning Glory and Asparagus Fern are present on

site and the construction work has the potential to

further spread these.

Invasion of native plant communities by African

Olive Olea europaea L. subsp. cuspidate

No African Olive was recorded within the study area

however the proposed upgrade has the potential to

introduce it.

Invasion, establishment and spread of Lantana

Lantana was recorded across the study area but

particularly on the western rail embankment around

Boongarra Reserve.

Invasion of native plant communities by

Chrysanthemoides monilifera (bitou bush and

boneseed)

Boneseed was recorded along the western fence of

the commuter carpark and could be spread by the

proposed upgrade.

Invasion of native plant communities by exotic

perennial grasses

Various exotic grasses were identified during the site

assessment, particularly in the mown exotic grass

and ornamental plantings community

Loss and degradation of native plant and animal

habitat by invasion of escaped garden plants,

including aquatic plants

Garden escapee species were recorded across the

study area and were dominant in the mown exotic

grass and ornamental planting community.

Loss of hollow-bearing trees three HBTs are proposed to be removed as part of

the Oatley station upgrade, and there is considered

to be some potential for roosting habitat of

threatened microbats to be impacted.

The proposed upgrade does have the potential to trigger a number of KTP's; however based on the

historically disturbed nature of the work and the restricted nature of vegetation removal, it is unlikely that any

potential increase will be significant.

5.2.2 Environmental Planning and Assessment Act, 1979

The EP&A Act was enacted to encourage the proper consideration and management of impacts of proposed

development or land-use changes on the environment (both natural and built) and the community. The Act is

administered by the NSW Department of Planning and Infrastructure.

Sections of the EP&A Act of primary relevance to the natural environment are considered further below in

relation to the current proposal.

5.2.2.1 Assessment of Significance (Section 5A)

Section 5A of the EP&A Act requires proponents and consent authorities to consider if a development will

have a significant effect on threatened species, populations or communities listed under the TSC Act and FM

Act. Section 5A (and Section 9A of the TSC Act) outlines seven factors that must be taken into account in an

AoS. Where any AoS determines that a development will result in a significant effect to a threatened species,

population or community a Species Impact Statement (SIS) is required.

Table 11 summarises the potential for the proposed development to have a significant effect on the

threatened flora and fauna species, populations or communities deemed to have a medium or greater

likelihood of occurrence within the study area (refer to Section3.4) and determines the need for an AoS under

Section 5A of the EP&A Act.

Assessments of Significance have been prepared for those species, populations or communities that are

deemed likely to be subject to negative impacts and are provided in Appendix 1 and 2. They indicate that a

significant impact is not likely to result from the proposal. A Species Impact Statement is therefore not

required.

5.2.2.2 State Environmental Planning Policies

State Environmental Planning Policies (SEPPs) outline policy objectives relevant to state wide issues. No SEPPs

are relevant to the current development

5.2.3 Native Vegetation Act, 2003

The NV Act provides for, encourages and promotes the management of native vegetation on a regional basis.

Under the NV Act no clearing of native vegetation is allowed except in accordance with prior development

consent from the relevant Council or under a Property Vegetation Plan (PVP) approved by the relevant

Catchment Management Authority.

Under Part 3 of Schedule 1 of the NV Act, Kogarah and Hurstville LGAs are classified as an urban area and

exempt from the provisions of the Act.

5.2.4 Noxious Weeds Act 1993

The NW Act was enacted to provide for the identification, classification and control of noxious weeds. Plants

declared as noxious weeds are currently listed under Weed Control Order No. 28 Declaring Certain Plants to

be Noxious Weeds published in the New South Wales Government Gazette No. 97. (Department of Premier


and Cabinet, 2011). Link for further information: http://www.dpi.nsw.gov.au/aboutus/about/legislation-

acts/noxious-weeds

Five species listed as noxious within the Kogarah and Hurstville City Council LGAs were recorded within the

study area (DPI, 2013). The details of these along with the legal requirements are outlined in Section 3.5; Table

8. A full list of exotic species, including declared noxious weeds identified in the study area are listed in

Appendix 1.

http://www.dpi.nsw.gov.au/aboutus/about/legislation-acts/noxious-weeds

http://www.dpi.nsw.gov.au/aboutus/about/legislation-acts/noxious-weeds


6. Conclusion

The study area supports two native (Degraded hinterland sandstone gully forest and Modified eucalypt

woodland) and two exotic (Mown exotic grasses and ornamental plantings and Exotic closed woodland)

vegetation communities. These vegetation communities are considered to be in poor condition due to past

disturbance.

The study area is of minimal value for threatened species, with no threatened flora species recorded or

considered likely to occur. The study area supports potential foraging and breeding habitat for one

threatened fauna species; suitable microbat hollows for the Eastern Freetail-bat were observed in a number

of trees surrounding the carpark, including two Sydney Red Gums, and one Spotted Gum.

No threatened ecological communities were recorded.

Five species listed as noxious within Hurstville and Kogarah City Council LGAs were recorded within the study

area.

The proposed upgrade of Oatley station will result in the removal of 0.04 ha of native vegetation (Modified

eucalypt woodland) and 12 native trees, including removal of a number of trees from the commuter carpark.

This includes potential roosting habitat for microbats, including the Eastern Freetail-bat.

In accordance with the Vegetation Offset Guide (TfNSW, 2013), a minimum of 112 native endemic trees

should be planted to compensate the required vegetation clearance. It is recommended that native species

such as Spotted Gum, Sydney Red Gum, Tallowood and Turpentine are used.

In addition to the impacts outlined above, various compound areas will be required for the storage of

equipment and infrastructure. The location of these compound areas is yet to be confirmed; however

potential areas within the study area have been identified and categorised based on their ecological values

(Figure 5).

The proposed bank stabilisation works are unlikely to result in any impacts to native vegetation or fauna

habitat; however the bank may currently be stabilised by mature trees and shrubs, and it is recommended

that the stumps of these trees and shrubs are kept in place to provide stability.

The overall impact of the proposed upgrade of Oatley station to native flora and fauna is considered to be

low. Measures to avoid and mitigate impacts are outlined in Section 4.

It is unlikely that the proposed works will result in a significant impact to threatened species, populations or

communities and additional approvals are not required.

The Southern Brown Bandicoot has a patchy

distribution. It is found in south-eastern NSW,

and are generally only found in heath or open

forest with a heathy understorey on sandy or

friable soils. They feed on a variety of ground-

dwelling invertebrates and the fruit-bodies of

hypogeous (underground-fruiting) fungi. Their

searches for food often create distinctive conical
