2 The Proposal

2.1 Key Characteristics

Table 1and Table 2 outline the key characteristics of the proposal.

Table 1: Proposal Summary Table Proposal Title Rottnest Lodge Redevelopment

Proponent Name Rottnest Island Authority

Short Description The proposal is for the redevelopment of the Rottnest Lodge on

Rottnest Island, WA.

The proposal will involve the demolition and/or refurbishment of

existing accommodation, the construction of new accommodation

and associated infrastructure.

The redevelopment is expected to be undertaken in 2021/2022.

Envelope

Clearing of up to 0.5 ha of native

vegetation within the 1.8 ha Development

Envelope is anticipated.

Operational Elements

Waste (sewage)

disposal

To be confirmed Septics connected to WWTP – expected

to be similar to the current

situation/extent given the overall volume

of accommodation is not expected to

increase significantly.

Irrigation of landscaped

areas

To be confirmed Gardens within the development site.

Stormwater

management

To be confirmed Capture and diversion of stormwater from

hardstand areas and roads within the

development site.

2.2 Local Context

The proposed Lodge Redevelopment area is located adjacent to Garden Lake (refer

Figure 1), which is a conservation significant area for a number of reasons, that are further

discussed in the following sections.

2.2.1 Lake Microbiology

Garden Lake, and surrounding Rottnest lakes, form a Nationally Important Wetland and

an Environmentally Sensitive Area with a Priority 1 Conservation Status: ‘Microbialites




and microbial mats of coastal hypersaline lakes (Rottnest Island)’ – Community 5 – Garden

Lake.

Various benthic microbial communities or algal mats are the dominant primary producers

in most of the coastal lakes. The biodiversity of these systems is significantly linked to a

large variety of avian fauna including migratory birds. The microbial mats in the salt lakes

of Rottnest Island are dominated by cyano-bacteria and diatoms. The microbial

communities in Rottnest Island salt lakes reflect the water quality, nutrient status and the

interactions between biota and the physicochemical environment (John et al. 2017).

Garden Lake does not form part of the development area but is afforded consideration

due as it is close to the proposed development and there is the possibility for direct and

indirect impacts during construction and operation if these activities are not appropriately

managed.

2.2.2 Flora and Vegetation

A Flora and Vegetation Study was undertaken at the proposal location, with the outcomes

summarised below. The vegetation units and conditions are mapped on Figure 2 and

Figure 3, respectively, and the detailed report is provided as Appendix A.

No Threatened flora species pursuant to the EPBC Act 1999 and/or gazetted as

Threatened/Declared Rare Flora pursuant to the Biodiversity Conservation Act 2016 and

Biodiversity Conservation Regulations 2018 were recorded during the survey (FVC 2019).

Three intact or remnant vegetation units were described and mapped for the study area,

comprising of two Woodlands, and one Shrubland (FVC 2019) as follows:

• Two woodlands:

o Allocasuarina huegeliana Low Open Woodland over Agonis flexuosa Tall

Open Shrubland

o Melaleuca lanceolata Low Woodland to Low Open Forest over Acacia

rostellifera Tall Sparse Shrubland over Acanthocarpus preissii and

Phyllanthus calycinus Shrubland over *Trachyandra divaricata, Euphorbia

peplus and Austrostipa flavescens.

• One shrubland

o Gahnia trifida Tall Sparse Sedgeland over Tecticornia indica subsp. bidens

and Atriplex cinerea Low Samphire Shrubland over *Cynodon dactylon

Low Sparse Grassland.

One vegetation unit representative of the ‘Vulnerable’ Subtropical and Temperate Coastal

Saltmarsh ecological community was mapped along the foreshore of Garden Lake. This

occurrence of the significant ecological community spans much of the lake fringe within

the Garden Lake study area. This area is adjacent, but outside, the Development Envelope.

The majority of the vegetation surrounding Garden Lake was found to be in ‘Degraded’ to

‘Completely Degraded’ condition.




Plate 1: Garden Lake Foreshore

One vegetation unit considered to be equivalent to known State listed TEC, SCP 30a –

Callitris preissii (or Melaleuca lanceolata) Forests and Woodlands was recorded at

Garden Lake.




Plate 2: Melaleuca species (Rottnest Island Teatree) within the development envelope

None of the terrestrial vegetation units defined within the study areas are considered

representative of any of the microbial PECs, SCP 29a (Coastal shrublands on shallow

sands) or the Banksia Woodland TEC (FVC 2019).

The vegetation was in a considerably poor condition, with 72.46% of the vegetation found

to be ‘Completely Degraded’ (CD). Only 1.28% of vegetation was recorded to be in

‘Degraded – Good’ (D-G) condition, the highest rating for the Garden Lake site (FVC

2019, Appendix A, Figure 3).

There is approximately 0.2 ha of vegetation within the Development Boundary that was

not surveyed; comprised of Melaleuca lanceolata and a mix of planted exotic species.

RIA has been undertaking rehabilitation within the foreshore areas for a number of years.




Plate 3: Rehabilitation areas adjacent Garden Lake Foreshore

2.2.3 Terrestrial Fauna

There were no specific fauna surveys targeted to the development area, however RIA

regularly monitor the Lake and adjacent areas for Quokka and bird species presence and

abundance.

RIA monthly monitoring shows that the foreshore and adjacent vegetated areas,

particularly to the north of Garden Lake, are heavily utilised by Setonix brachyurus

(Quokka,), which is listed ‘Vulnerable’ under the EPBC Act (federal) and ‘Threatened’

under the BC Act (state).




Plate 4: Quokkas utilising the habitat to the north of Garden Lake

Garden Lake, and other adjacent Rottnest Lakes, are utilised by a number of species of

migratory waterbirds. One conservation significant species – Calidris ruficollis (Red-

necked Stint, Marine/Migratory) is known to utilise Garden Lake and its foreshore for

foraging (RIA 2019).

Plate 5: Stilts foraging in the shallows of Garden Lake




A NatureMap search returned 39 species of conservation significance and a further 174

species of non-conservation significant taxon within a 2 km radius of the site (refer

Appendix B). The majority of records were mobile species (birds), with only one known

species utilising the area (Calidris ruficollis). The remaining species that are likely to be

encountered in the proposal area are outlined in Table 3.

3 Impact Assessment

3.1 Key Factors

This section details the potential impacts of key environmental factors as identified within

the referral form. Each section has been developed with consideration of the appropriate

Environmental Factor Guideline (EFG) as relevant to the factor.

3.1.1 Flora and Vegetation

Table 4 details the relevant policy and guidance, consultation, existing environment,

proposed activities, management and mitigation strategies, and any relevant assumptions.

This information is provided to support Part B of the Referral.

Table 4: Flora and Vegetation Impact Assessment

EPA Factor: Flora and Vegetation

EPA policy

and guidance

EFG: Flora and Vegetation (EPA 2016a)

The proposal has considered and actively avoided sensitive environmental

areas (namely vegetation along the Garden Lake foreshore) and its

implementation involves minimal clearing within the development envelope.

Consultation Meeting with Office of the EPA – Hans Jacob

• Discussed minimal clearing with retention of conservation significant

lake foreshore vegetation.

Receiving

environment

Flora assessment (FVC 2019, Appendix A)

For a detailed overview please refer to Section 2.2.2.

Proposal

activities

The following construction activities have the potential to impact flora and

vegetation within the development envelope:

• Clearing of an extent of conservation significant native vegetation to

allow for the redevelopment of accommodation facilities and

associated infrastructure

• Machinery utilised as part of the development introducing or

spreading disease and/or weeds.

The following operational activities have the potential to impact flora and

vegetation:

• Increased pressure on the littoral vegetation by additional foot traffic

adjacent Garden Lake.

Mitigation The key mitigation strategy is to avoid clearing where possible, but where

clearing is necessary, the following strategies will be employed:

• Clearly define vegetation for retention in the project specific

Construction Environmental Management Plan (CEMP)

• Retain foreshore vegetation and recently rehabilitated areas (not

included within the Development Envelope, Proposal Footprint)

• Control public access to foreshore zone (i.e. controlled access).

Impacts The residual impact on the EPA Objective is considered to be minor.




EPA Factor: Flora and Vegetation

Assumptions The retention of vegetation will be possible following a bushfire assessment.

3.1.2 Terrestrial Environmental Quality




Table 5: Terrestrial Environmental Quality Impact Assessment

EPA Factor: Terrestrial Environmental Quality

EPA policy and

guidance

EFG: Terrestrial Environmental Quality (EPA 2016b)


Receiving

environment

The southwest corner of the development envelope is mapped as having

a moderate to low risk of acid sulfate soils (ASS) occurring within 3m of

the natural soil surface. Site surveys undertaken at the golf course

adjacent to Garden Lake indicated that the area is a low risk for ASS

(GHD 2016).

Proposal activities The following construction activities have the potential to impact the soils

within the development envelope:

• Potential exposure of ASS

• Contamination of soil during construction activities (e.g.

accidental spills)

• Erosion resulting from vegetation clearing and altered land use.

Mitigation The following mitigation strategies will be implemented:

• Waste management and spill procedures detailed in the site-

specific CEMP

• ASS assessment and management through further

investigations, where applicable.

Impacts The residual impact on the EPA Objective is considered to be negligible.

Assumptions Management strategies will be enforced through the DA process.

areas and involves minimal clearing of utilised and potential habitat areas.





EPA Factor: Terrestrial Fauna

Receiving

environment

For a detailed overview, please refer to Section 2.2.3.

Proposal activities The following construction activities have the potential to impact

terrestrial fauna:

• Displacement of fauna by avoidance (e.g. fauna may temporarily

retreat from the immediate area to avoid noise)

• Vehicle strike resulting in injury or death

• Habitat loss affecting the health and survival of individual species

and populations

• Reduction or prevention of access to feeding or roosting habitats.

The following operational activities have the potential to impact terrestrial

fauna:

• Increased public presence in the natural habitat of fauna species,

most notably the Quokka.


• Development envelope excludes significant Quokka habitat to the

north of Garden Lake

• Foreshore vegetation will remain intact and the development will

be set back from the Garden Lake foreshore to ensure separation

to conservation significant migratory birds

• Continue monitoring efforts (avian species and Quokkas)

• Lease boundary to exclude highly utilised fauna habitat to the

north of Garden Lake.


Assumptions The lease boundary and defined activities can be managed through the

DA process.

areas and involves minimal clearing. Considerations have been implemented

to maintain the hydrological regimes and quality of groundwater and surface

water so that environmental values are protected


Receiving

environment

Garden Lake is a terminal water body and is highly saline. The lake is fed by

direct rainfall and groundwater, as well as from a drainage system from the

settlement area via a concrete pipe (approximately 200mm in diameter)




EPA Factor: Inland Waters

located on the eastern shoreline. A site visit in March 2014 recorded

freshwater seeps evident along the eastern shoreline, particularly in front of

reed beds and old water infrastructure. (Hatch 2014)

Garden Lake is a registered ESA – for further information please refer to

Section 2.2.1.

Water quality studies of the lake and adjacent groundwater bores is

undertaken as a routine practice, engaged by RIA.

Proposal

activities

The following construction activities may impact the hydrological regimes

and/or water quality of Garden Lake:

• Water quality reduced through construction activities (e.g. accidental spills)

• Potential impacts to microbial communities by altered hydrological regimes (surface and groundwater flow) and hydrology and water chemistry (salinity and nutrients)

• Increased sedimentation

The following operational activities may impact the hydrological regimes

and/or water quality of Garden Lake:

• Increased public usage and potential pollution of the lake

• Stormwater runoff from roads and hardstand areas within the

development

• Abstraction of groundwater for consumptive uses

• Diversion of surface water systems and construction or significant

modification to drainage systems which intercept groundwater

including those where drainage water is discharged

• Drainage construction directly impacting on, or which lead to the

discharge of drainage water to Garden Lake.

Mitigation The following mitigation strategies will be implemented during construction:

• Waste management and spill procedures developed and implanted

through the site specific CEMP

• Drainage Management through design specifications

• Continue monitoring effort for microbialites

• The appropriate siting of waste structures in a catchment

• Minimise/manage alteration of the surface and groundwater regimes

• Manage sedimentation through design

• Continued monitoring efforts, including lake water quality,

groundwater quality and microbial activity.


Assumptions Stormwater and wastewater are adequately managed.

It is expected management of these will be enforced through the

Development Approval Conditions.




3.1.5 Social Surroundings




Table 8: Social Surroundings Impact Assessment

EPA Factor: Social Surroundings

EPA policy

and guidance

EFG: Social Surroundings (EPA 2016d)

The proposal considered potential impacts to social surroundings, with

particular focus on cultural heritage and aesthetics.


• Discussed heritage consultations to date and the pending application

• Section 18 approvals pending.

Whadjuk Working Party and Wadjemup Aboriginal Reference Group briefing

and discussions

• Groups requested to be consulted during the development of the

Design Guidelines.

Activity Notice lodged to SWALSC March 2019.

Receiving

environment

An Aboriginal Heritage Assessment (Yarran 2012) was undertaken as part of

a previous redevelopment proposal that has now been significantly reduced in

scale. The survey revealed that the current lease area includes buildings

located within the ‘Rottnest Lodge/Quod’ Registered Aboriginal Site 3540

(refer Figure 1).

The proposed development envelope for this proposal (refer Figure 1) excludes

this location.

Proposal

activities

Construction activities have the potential to impact social surroundings in the

following ways:

• Disturbance of significant heritage sites, e.g. scatter

• Temporarily reduced amenity (noise, dust, light).

Mitigation The following mitigation strategies will be implemented during construction:

• Clearly define known significant heritage sites (refer Figure 1)

• Site induction to include:

o Briefing on significant heritage locations

o Unexpected finds procedures, including legislative and

reporting requirements

o Section 18 conditions

• Erect signage informing the public of the development stages

• Ensure compliance with applicable legislation that will be detailed in the

site-specific CEMP, including but not limited to: Environmental

Protection (Noise) Regulations 1997.

Impacts The residual impact on the EPA Objective is expected to be positive as the

proposal aims to remove infrastructure from a culturally significant place (the

Quod).




EPA Factor: Social Surroundings

Assumptions RIA believe that the proposed redevelopment will improve the visual amenity

of the area and improve the linkage of adjacent Aboriginal Heritage places by

provided greater separation from a significant heritage place.

3.2 Other Factors

This section details the potential impacts of all other factors not identified as key

environmental factors within the referral form. This section does not outline any of the EPA

Theme: Sea factors as they are not relevant to the proposal.

3.2.1 Subterranean Fauna




Table 9: Subterranean Fauna Impact Assessment

EPA Factor: Subterranean Fauna

EPA policy and

guidance

EFG: Subterranean Fauna (EPA 2016e)

The proposal has considered the likelihood of subterranean fauna being

present and the possibility of impact to these taxa.

Consultation No specific consultation for this factor.

Receiving

environment

The site contains an underlying groundwater aquifer but no known cave

system so there is the possibility of stygofauna, but unlikely to have

troglofaunal present.

A survey undertaken on a number of bores through the centre of the island

reported the following occurrences (Sacco 2017):

• A total of 52 records of six different taxon were recorded over six

bore locations

• Eleven records of three different taxa (Mollusca, Oligochaeta and

Parabathynellidae) were recorded within three bores located

approximately 5 km west of the site

• 41 records of five different taxa (Nematoda sp., Mollusca,

Hydracarina, Harpacticoida and Parabathynellidae) were recorded

within three bores located approximately 3 km southwest of the site.

It is unknown if any of these taxa are of conservation significance as they

were not identified to species level.




EPA Factor: Subterranean Fauna

Proposal

activities

The following proposed activities have the potential to impact subterranean

fauna:

• Construction activities, including but not limited to the installation of

footings that may require dewatering, however this is considered

unlikely

• Changes in surface topography due to compaction or creation of hard

surfaces resulting in altered groundwater flow paths, increased

runoff, and reduced infiltration and aquifer recharge

• Clearing of vegetation leading to sedimentation and changed nutrient

inputs.

Mitigation Where dewatering is required, management strategies shall be included in

the CEMP, which will be specifically prepared for the implementation of the

proposal. Where significant dewatering is required, a Licence will be applied

for and shall involve the preparation of an Acid Sulfate Soils and Dewatering

Management Plan (ASSDMP) should this be required.

Impacts The residual impact on the EPA Objective is considered to be negligible.

Assumptions Dewatering is not expected to be required as part of the proposal.

No changes to the groundwater flow path as a result of changes to surface

topography.

3.2.2 Landforms




Table 10: Landforms Impact Assessment

EPA Factor: Landforms

EPA policy and guidance EFG Landforms (EPA 2018c)

The proposal has considered and actively avoided potentially harmful or

significant pollutants. Considerations have been implemented to maintain air

quality and minimise emissions so that environmental values are protected

Consultation None required.

Receiving

environment

Rottnest Island is a relatively clean environment with minimal air pollution

attributed to the limited number of permanent vehicles operating on the island.

Proposal

activities

The following construction activities have the potential to impact air quality:

• Exhaust emissions from site machinery and/or vehicles

• Dust emissions from driving on unsealed roads/tracks.

The following operational activities have the potential to impact air quality:

• Potential increase in GHG emissions in the running of the Lodge post

redevelopment, considering the likely increase in use of

accommodation facilities.


• Ensure all construction vehicles and equipment are well maintained and

serviced to reduce risk of excess emissions

• Dust suppression measures, e.g. water truck, that are adequate to

ensure visible dust is not emitted from the site

• Environmentally sustainable lighting options such as LED should be

considered to reduce GHG emissions during operations.

Impacts The majority of the impacts will be temporary and the residual impact on the

EPA Objective is considered to be minor.

Assumptions Maintenance of machinery is adequate to ensure minimal exhaust emissions to

the air.

Dust suppression measures, where considered necessary, are adequate to

ensure visible dust does not travel beyond the site boundary.

EXE CUTIVE SUMMARY Rottnest Island is governed by the Rottnest Island Authority Act, 1987 (the Act), which establishes the Rottnest Island Authority (RIA) as a statutory body to control and manage the island. Focused Vision Consulting Pty Ltd (FVC) was commissioned by RIA to undertake a single-phase, detailed flora and vegetation survey and prepare an associated technical report for two sites; Garden Lake and Bickley. The survey was required to assess opportunities and constraints in relation to potential site development. This report presents the findings of the assessment conducted within the two sites during spring 2018.

A single-phase, detailed flora and vegetation survey was carried out with the two designated areas on 25 October 2018 by FVC’s Principal Ecologist, Kellie Bauer-Simpson and Senior Botanist, Lisa Chappell.

The key findings and conclusions arising from the flora and vegetation assessment within the study area are as follows:

No flora species listed as Threatened or Priority under the WC Act or under the EPBC Act were recorded. Six intact or remnant vegetation units were described and mapped for the study area, comprising of three

Woodlands, one Shrubland, one Sedgeland and one Heath. One vegetation unit (TiSS) is considered to be representative of the ‘Vulnerable’ Subtropical and

Temperate Coastal Saltmarsh ecological community. Where possible, direct impacts from clearing or indirect impacts that may influence hydrological regimes applicable to this ecological community should be minimised or avoided.

One vegetation unit (MlArS) is considered to be equivalent to known State listed TEC, SCP 30a – Callitris preissii (or Melaleuca lanceolata) Forests and Woodlands. Where possible, clearing of this vegetation unit should be minimised or avoided.

One Declared Pest plant listed under the Biosecurity and Agriculture Management Act 2007 (BAM Act) (One Leaf Cap Tulip) was recorded within two vegetation units (GtS and ApH) at the Bickley site, adjacent to the airport. One Leaf Cape Tulip is listed as a Declared Plant under Section 22 of Act, however, it is currently exempt from specific management control.

1. INTRODUCTION

1.1 BACKGROUND

Rottnest Island, off the coast of Perth, Western Australia, is a haven for native wildlife, and is listed as an A-Class Nature Reserve. The island is governed by the Rottnest Island Authority Act, 1987 (the Act), which establishes the Rottnest Island Authority (RIA) as a statutory body to control and manage the island. The Act gives RIA the power to control and manage the island for the purposes of the provision of recreational and holiday facilities, for the protection of the flora and fauna and to maintain and protect the natural environment and the man-made resources of the island to the extent that RIA’s resources allow.

Focused Vision Consulting Pty Ltd (FVC) was commissioned by RIA to undertake a single-phase, detailed flora and vegetation survey in accordance with Technical Guidance – Flora and Vegetation Surveys for Environmental Impact Assessment (Environment Protection Authority 2016) and prepare an associated technical report for the following two sites on Rottnest Island (Figure 1):

1. Garden Lake 2. Bickley (site includes wetland listed in ‘Directory of Important Wetlands’, low Acanthocarpus preissii heath

Community, and Melaleuca lanceolata/Callitris preissii).

The survey was required to assess opportunities and constraints in relation to potential site development. This report presents the findings of the assessment conducted within the two sites during October 2018.

1.2 SCOPE OF WORK

The scope of work required to be fulfilled was as follows:

Undertake a desktop assessment of the flora and vegetation Undertake a site assessment of the two sites for flora and vegetation values Prepare a report compiling the findings of the site assessment.

2. LEGISLATIVE CONTEXT

The flora and vegetation assessments were conducted in accordance with the following legislation:

Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) Western Australian Environmental Protection Act 1986 (EP Act) Western Australian Wildlife Conservation Act 1950 (WC Act).

The assessments complied with requirements for environmental survey and reporting in Western Australia, as outlined in:

EPA (2000) Position Statement No. 2: Environmental Protection of Native Vegetation in Western Australia

EPA (2002) Position Statement No. 3: Terrestrial Biological Surveys as an Element of Biodiversity Protection

EPA (2008) Guidance Statement No. 33: Environmental Guidance for Planning and Development EPA (2016) Technical Guidance – Flora and Vegetation Surveys for Environmental Impact Assessment.

2.1 THREATENED AND PRIORITY FLORA

The Department of Biodiversity, Conservation and Attractions (DBCA) assigns conservation status to endemic plant species that are geographically restricted to few known populations or threatened by local processes. Allocating conservation status to plant species assists in protecting populations and conserving species from potential threats.

Threatened flora species are gazetted under subsection 2 of section 23F of the WC Act. It is an offence to “take” or damage Rare Flora without Ministerial approval. Section 23F of the WC Act defines “to take” as “to gather, pick, cut, pull up, destroy, dig up, remove or injure the flora or to cause or permit the same to be done by any means.”

Species designated as Priority Flora are under consideration for declaration as ‘Threatened Flora’ and are in urgent need of further survey (Priority 1 to 3) or require monitoring every 5-10 years (Priority 4). Table 1 presents the definitions of Threatened and the four Priority ratings under the WC Act as extracted from DBCA (DBCA 2019a).

Threatened Species

Published as Specially Protected under the Wildlife Conservation Act, 1950 and listed under Schedules 1 to 4 of the Wildlife Conservation (Rare Flora) Notice for Threatened Flora.

Flora that has been declared to be ‘likely to become extinct or is rare, or otherwise in need of special protection’, pursuant to section 23F (20) of the Wildlife Conservation Act.

P1

Priority 1 – Poorly Known Species

Species that are known from one or a few locations (generally five or less) which are potentially at risk. All occurrences are either: very small; or on lands not managed for conservation, e.g. agricultural or pastoral lands, urban areas, road and rail reserves, gravel reserves and active mineral leases; or otherwise under threat of habitat destruction or degradation. Species may be included if they are comparatively well known from one or more locations but do not meet adequacy of survey requirements and appear to be under immediate threat from known threatening processes. Such species are in urgent need of further survey.

P2


Species that are known from one or a few locations (generally five or less), some of which are on lands managed primarily for nature conservation, e.g. national parks, conservation parks, nature reserves and other lands with secure tenure being managed for conservation. Species may be included if they are comparatively well known from one or more locations but do not meet adequacy of survey requirements and appear to be under threat from known threatening processes. Such species are in urgent need of further survey.

P3


Species that are known from several locations, and the species does not appear to be under imminent threat, or from few but widespread locations with either large population size or significant remaining areas of apparently suitable habitat, much of it not under imminent threat. Species may be included if they are comparatively well known from several locations but do not meet adequacy of survey requirements and known threatening processes exist that could affect them. Such species are in need of further survey.

P4

Priority 4 – Rare, Near Threatened and other species in need of monitoring

(a) Rare. Species that are considered to have been adequately surveyed, or for which sufficient knowledge is available, and that are considered not currently threatened or in need of special protection but could be if present circumstances change. These species are usually represented on conservation lands.

(b) Near Threatened. Species that are considered to have been adequately surveyed and that are close to qualifying for Vulnerable but are not listed as Conservation Dependent.

(c) Species that have been removed from the list of threatened species during the past five years for reasons other than taxonomy.


Under the EPBC Act, actions that have, or are likely to have, a significant impact on any matter of national environmental significance (MNES) require approval from the Federal Minister for the Environment.

Species at risk of extinction are recognised as Threatened at a Commonwealth level and are categorised according to the EPBC Act as summarised in Table 2.

Table 2 Categories of EPBC Act Threatened Flora Species

CD

Conservation Dependent

Taxa whose survival depends upon ongoing conservation measures. Without these measures, a conservation dependent taxon would be classified as Vulnerable or more severely threatened

Any species listed in State and Commonwealth legislation as being of conservation significance is said to be a significant species. This incorporates species that are endangered, vulnerable and rare or covered by international conventions. Significance is not limited to species covered by State and Commonwealth legislation and also includes species of local significance and species showing significant range extensions or at the edge of their known range.

2.2 THREATENED AND PRIORITY ECOLOGICAL COMMUNITIES

Threatened Ecological Communities (TECs) are naturally occurring biological assemblages that occur in a particular type of habitat, which are subject to processes that threaten to destroy or significantly modify the assemblage across its range (DEC 2007).

Vegetation communities in Western Australia are described as ‘TECs’ if they have been defined by DBCA’s Species and Communities Branch and found to be either Presumed Totally Destroyed (PD), Critically Endangered (CR), Endangered (EN) or Vulnerable (VU). The categories and the criteria for defining TECs have been described by English and Blyth (1997). A publicly available database listing TECs within Western Australia is maintained by DBCA.


There is currently no legislation covering the conservation of TECs in WA, however some are protected under the Commonwealth EPBC Act. The TECs on the Commonwealth register are also listed on the Department of the Environment and Energy (DEE) register on their website and in the Protected Matters Database. For those State TECs not listed on the Commonwealth register, land clearing legislation under the EP Act also provides protection. The EPA’s position on TECs states that proposals resulting in the direct loss of TECs are likely to be formally assessed. Additionally, State listed TECs will be afforded protection under the new Biodiversity and Conservation Act 2016, once implemented.

Additional to TECs, ecological communities that are considered potentially of conservation significance (and potentially TECs) that do not currently meet survey criteria or that are not adequately defined, are rare but not threatened, have been recently removed from the TEC list or require regular monitoring are considered to be Priority Ecological Communities (PECs) (DEC 2013) and they are required to be taken into consideration during environmental impact assessments.

2.3 INTRODUCED FLORA

To date, over 1,200 introduced flora (weed) species have been recognised to occur within Western Australia (EPA 2007). Introduced flora (weeds) are plants that are not indigenous to an area and have been introduced either directly or indirectly through human activity. They establish in natural ecosystems and adversely modify natural processes, resulting in the decline of the invaded community and the habitat value provided for native fauna. Weeds threaten the survival of many flora because of their rapid growth and the ability to out-compete native plants for available nutrients, water, space and sunlight.

2.3.1 Weeds of National Significance

Under the National Weed Strategy, there are currently 32 weed species listed as Weeds of National Significance (WONS). Each weed was considered for inclusion based on the following criteria; invasive tendencies, impacts, potential for spread and socioeconomic and environmental values.

2.3.2 Declared Pest Plants

The Western Australian Organism List (WAOL) details organisms listed as Declared Pests, including pest plants, under the Biosecurity and Agriculture Management Act 2007 (BAM Act) (DPIRD 2018). Under the BAM Act, Declared Pests are listed under one of the following categories:

C1 (exclusion), that applies to pests not established in Western Australia; control measures are to be taken to prevent their entry and establishment

C2 (eradication), that applies to pests that are present in Western Australia but in low numbers or in limited areas where eradication is still a possibility

C3 (management), that applies to established pests where it is not feasible or desirable to manage them in order to limit their damage.

2.3.3 Environmental Weeds

Introduced species have also been ranked by a number of attributes, including invasiveness, distribution and environmental impacts in the various regions in Environmental Weed Strategy for Western Australia (CALM 1999). To advance the above categorisation, the Invasive Plant Prioritisation Process for DBCA was developed in 2008 (DPaW 2013).


2.4 LOCALLY OR REGIONALLY SIGNIFICANT VEGETATION

Vegetation may be locally or regionally significant in addition to significance according to statutory listings.

Vegetation communities are referred to as locally significant where they:

support populations of Priority Flora species extend the geographic range of particular taxa from previously recorded locations are restricted to only one or a few locations occur as small isolated communities exhibit unusually high structural and species diversity.

Vegetation communities are referred to as regionally significant where they:

are limited to specific landform types are uncommon or restricted plant community types within the regional context support populations of threatened flora.

Vegetation communities are referred to as Nationally significant where they:

support populations of Threatened (EPBC listed) species support TECs listed as nationally (EPBC) significant.

Technical Guidance for Flora and Vegetation Surveys for Environmental Impact Assessment (EPA 2016) also states that vegetation may be considered significant for a range of reasons, including but not limited to the following:

being identified as threatened or priority ecological communities have a restricted distribution have a degree of historical impact from threatening processes have a role as a refuge provide an important function required to maintain ecological integrity of a significant ecosystem.

2.5 VEGETATION CLEARING, EXTENT AND STATUS

Clearing of native vegetation is regulated in WA under the EP Act and the Environmental Protection (Clearing of Native Vegetation) Regulations 2004. Any clearing of native vegetation is an offence, unless carried out under a clearing permit or if the clearing is for an exempt purpose (DWER 2018). A clearing permit is required under Part V of the EP Act, whereby permit applications to clear native vegetation must be assessed against the ’10 Clearing Principles’ as outlined in the regulations.

Where clearing of native vegetation is proposed to occur, there are several key criteria applied to the assessment of clearing permit applications, in the interests of biodiversity conservation.

The objective of the EPA in relation to flora and vegetation is: To protect flora and vegetation so that biological diversity and ecological integrity are maintained (EPA 2016b). This objective is documented in the EPA Factor Guideline - Flora and Vegetation (EPA 2016b), which has superseded a number of documents including Position Statement No. 2 (EPA 2000). With a lack of quantifiable retention targets outlined in new Factor Guideline, the 30% threshold/retention target as documented in Position Statement 2 remains a useful guideline for determining whether or not adequate proportions of native vegetation are being conserved.

Position Statement No. 2 (EPA 2000) outlined criteria aimed to help reverse the long-term decline in the quality and extent of Western Australia’s native vegetation cover.


The criteria, as defined in the now superseded document, were as follows:

the “threshold level” below which species loss appears to accelerate exponentially at an ecosystem level is regarded as being at a level of 30% of the pre-clearing extent of the vegetation type

a level of 10% of the original extent is regarded as being a level representing “endangered” clearing which would put the threat level into the class below 10% should be avoided from a biodiversity perspective, stream reserves should generally be in the order of at least 200 m wide.

The status of remaining vegetation can be delineated into five different classes:

Presumed extinct - probably no longer present in the bioregion Endangered - <10% of pre-European extent remains* Vulnerable - 10-30% of pre-European extent exists* Depleted - >30% and up to 50% of pre-European extent exists* Least concern - >50% pre-European extent exists and has been subject to little or no degradation over a

majority of this area. * or a combination of depletion, loss of quality, current threats and rarity gives a comparable status.

2.6 ENVIRONMENTALLY SENSITIVE AREAS

Environmentally Sensitive Areas (ESAs) are areas that require special protection due to aspects such as landscape, wildlife or historical value and are generally considered to be areas of high conservation value. ESAs are declared in the Environmental Protection (Environmentally Sensitive Areas) Notice 2005, which was gazetted on 8 April 2005.

There are several types of ESAs relating to flora and vegetation, declared under Part V of the EP Act, which include:

a defined wetland and the area within 50 m of that wetland the area covered by vegetation within 50 m of rare (Threatened) flora, to the extent where the vegetation

is continuous with the vegetation in which the rare (Threatened) flora is located the area covered by a TEC Bush Forever sites areas covered by the following policies:

o Environmental Protection (Gnangara Mound Crown Land) Policy 1992 o Environmental Protection (Western Swamp Tortoise) Policy 2002 o Environmental Protection (Swan Coastal Plain Lakes) Policy 1992 o Environmental Protection (South West Agricultural Zone Wetlands) Policy 1998

areas of native fringing vegetation in the policy area as defined in Environmental Protection (Swan and Canning Rivers) Policy 1998.

There are 89 recognised Interim Biogeographic Regionalisation for Australia (IBRA) regions across Australia that have been defined based on climate, geology, landforms and characteristic vegetation and fauna (Commonwealth of Australia 2013).

The study area lies within the Swan Coastal Plain IBRA region and, at a finer scale, within the Perth subregion (Mitchell et al. 2002). This subregion is part of the South West Botanical Province which supports a very high level of species diversity. Mitchell et al. (2002) describe the Swan Coastal Plain as a low lying coastal plain mainly covered with woodlands. It is dominated by Banksia or Tuart on sandy soils, Casuarina obesa on outwash plains and paperbarks in swampy areas.

3.3 GEOLOGY AND SOILS

Rottnest Island is part of an extensive Quaternary limestone dune system and is part of a chain of aeolian dunes known as the Spearwood Dune System (RIA 2014a). The sediment comprising the Spearwood Dune System developed from Tamala Limestone, which is predominantly cemented quarts sands, but also contains an extensive coastal assemblage of shells and coral fragments (Playford 1988).

At a finer scale the study area traverse four differing soil types as presented in Table 3.

The objective of the Environmental Protection Authority (EPA) in relation to flora and vegetation is: To protect flora and vegetation so that biological diversity and ecological integrity are maintained (EPA 2016b). The EPA considers it is important that ecological communities are maintained above a threshold level of 30% of the original pre-clearing extent of each community (EPA 2008). A level of 30% pre-clearing extent is considered to be the level below which species loss appears to accelerate exponentially at the ecosystem level (EPA 2008).

The following key criteria are applied to vegetation clearing from a biodiversity perspective, which justifies the retention targets (EPA 2000):

the ‘threshold level’ below which species loss appears to accelerate exponentially within an ecosystem level, is regarded as being at a level of 30% (of the pre-European, i.e. pre-1750 extent of the vegetation type)

a level of 10% of the original extent of a vegetation community is regarded as being a level representing Endangered

clearing which would increase the threat level to a vegetation community should be avoided.

All of the vegetation units exceed the 30% threshold level; and therefore, the remaining extents meet the EPA objective for retention for the purpose of biodiversity conservation.

4. METHODOLOGY

The assessments for flora and vegetation values were carried out in accordance with Environmental Protection Authority (EPA) (2016) Technical Guidance – Flora and Vegetation Surveys for Environmental Impact Assessment.

4.1 DESKTOP ASSESSMENT

Results of searches of the Department of Biodiversity, Conservation and Attractions (DBCA) Threatened and Priority Flora and Ecological Communities databases were compiled for the desktop assessment. Other available information was also sourced through searches of NatureMap and the Commonwealth DEE Protected Matters Search Tool, for Matters of National Environmental Significant (MNES) associated with the sites.

Information provided by RIA relating to previous surveys within and adjacent to the sites were reviewed as part of the desktop assessment.

The suite of information gathered from the desktop assessment was used to generate potential species lists tailored to the two study sites, with a focus on Threatened and Priority flora and ecological communities and assisted in determining species and areas of focus during the field assessment.

4.2 FIELD ASSESSMENT

A single-phase, detailed flora and vegetation survey at two sites (Garden Lake and Bickley) was carried out on 25 October 2018 by Principal Ecologist, Kellie Bauer-Simpson and Senior Botanist, Lisa Chappell. Field data was collected using an electronic table with customised data forms and mobile spatial mapping capability, within the software program, Mappt™.

Across the two sites, data was collected from three non-permanent 10 m x 10 m flora and vegetation assessment quadrats where native vegetation was found to be in ‘Good’ or better condition, in accordance with EPA requirements for a detailed assessment (EPA 2016a) and from four detailed data collection points (relevés, where vegetation was not found to be in ‘Good’ or better condition) (Figure 4). All three of the quadrats were recorded within the Bickley study area. Observations and opportunistic data collection was recorded continuously within and throughout both study areas.

The following information was collected at each quadrat:

botanist date quadrat/site code GPS location (MGA94) representative photograph from the north-west corner landform and soil description topography/slope time since fire vegetation condition/degradation/disturbances (e.g. grazing, weed invasion, fire) comprehensive list of flora species observed, including average height and estimated projected foliage

cover of dominant species within each stratum vegetation condition, assessed against the currently accepted scale; an adaptation of the Keighery

(1994) and Trudgen (1988) condition scales.

Prior to the field survey, the locations of any Threatened and Priority flora retrieved from the various database searches and literature reviews as part of the desktop assessment were collated. A proportion of the field


assessment time was dedicated to selected targeted searches for relevant flora, in suitable habitats. Conservation significant flora was opportunistically surveyed throughout the field assessment of the sites.

Where observed, the location of each potentially significant taxon collected was to be recorded using a GPS enabled tablet or a handheld GPS, and the local abundance, landform and associated flora species noted. To determine the size and extent of significant flora populations, detailed counts were to be undertaken except where populations were large or widespread, in which case the population was to be estimated using methods consistent with the Threatened and Priority Flora Report Form – Field Manual (DBCA 2017).

The flora and vegetation data collected from the combination of quadrats, relevés, traverses and continuous opportunistic observations contributed to the flora inventory for the study, which included weeds.

The information collected from quadrats, relevés, traverses and continuous opportunistic observations was utilised to digitise mapping boundaries for the range of vegetation units present within the study area, as well as the varying vegetation condition. This mapping was refined following return from the field, using GIS mapping software, QGIS, and based on initial mapping prepared in the field, on mobile/tablet devices.

Vegetation was classified based on the dominant species and vegetation structure. The structural vegetation classification satisfied the requirements of NVIS Level 5 vegetation descriptions

Vegetation condition was recorded at quadrats and relevés and where other areas of varying condition were observed. The vegetation condition was then mapped across the study area at the same scale as the vegetation mapping. Vegetation condition ratings followed the scale recommended for the South West Botanical Province (EPA 2016, an adaptation of the Keighery (1994) and Trudgen (1988) condition scales).

Flora identifications were undertaken by specialist taxonomist, Shibi Chandran. Plant group specialist taxonomists were consulted as required for challenging identifications. Taxonomy and nomenclature followed current protocols of the WA Herbarium.

The limited amount of data collected (three quadrats) as a result of the small and degraded study sites was determined to be unsuitable for formal floristic analysis using PATN™ software. Rather, the present species recorded from quadrats were compared with species recorded by Gibson et al. (1994) in the study which mapped FCTs of the Swan Coastal Plain.

4.3 STUDY LIMITATION

The limitations of the flora and vegetation assessment have been considered in accordance with the Technical Guidance (EPA 2016) and these are summarised in Table 5.

Table 5 Study Limitations

Aspect Constraint? Commentary

Availability of regional data No

A comprehensive survey of vascular flora of the island was carried out between 1998 – 2000 by the Rottnest Voluntary Guides and WA Herbarium (Rippey et al. 2002). Broader Swan Coastal Plain data is also available from the FCT mapping study compiled in Gibson et al. (1994), although this reference is now considered quite out of date.

Scope (detail) No

Detailed flora and vegetation assessments were carried out in accordance with EPA (2016). A collective total of three quadrats were sampled within vegetation unit, MlArs where ‘Good’ or better condition vegetation occurs. These results were sufficient to conclude the FCT represented.

Experience of personnel No

All of the personnel undertaking the field assessment, flora identifications, data analysis, vegetation mapping and reporting are experienced botanists, with specialist skills in their respective fields. The field botanists and reporting personnel have 16 and 20 years’ experience in botanical assessments in Western Australia.

Survey effort/detail/intensity No Two personnel undertook the detailed flora and vegetation field assessment within the study area over a six-hour period with three quadrats and four relevés recorded.

Seasonal timing and climatic conditions

No The field assessment was conducted during the optimal flowering season (October).

Access No The entire study area was easily accessible on foot.

Mapping reliability No The mapping has been prepared at a scale based on mostly ground-truthed areas, with limited extrapolation, given the good accessibility for most of the study area. Therefore, mapping reliability based on scale is considered high.

Disturbances No

The settlement area is highly modified. The Garden Lake and Bickley sites have both been subject to a high level of disturbance such as access tracks, development and clearing with weed invasion, erosion and other degradation resulting. Only a small portion of the Bickley site was considered to be in ‘Good’ or better condition.

Survey completeness No The entire study area was easily accessible and surveyed completely.


5. RESULTS

5.1 DESKTOP ASSESSMENT

The results of the DBCA database searches, NatureMap Species Report and the Commonwealth Department of the Environment and Energy (DEE) Protected Matters Search Tool, for Matters of National Environmental Significant (MNES) returned results for the potential presence of conservation significant flora, and ecological communities within the study areas (Appendices A and B). The results of the desktop assessment are presented in the following sections.

5.1.1 Threatened and Priority Flora

A total of six Threatened and/or Priority flora were identified through the desktop assessment to previously occur or to occur within close proximity to the study areas (Table 6, Figure 5). This comprised one Threatened flora, two Priority 1 flora, one Priority 2 flora and two Priority 4 flora species. Based on previous records, current known distribution and preferred habitats, it was determined that all six of these species are likely to or may have the potential to occur within the study areas (Table 6).

5.1.2 Threatened and Priority Ecological Communities

A review of the DBCA Threatened and Priority Ecological Communities (TEC and PEC) database, interrogation of the EPBC Protected Matters Search Tool, a review of information provided by the RIA and other documents prepared by RIA (2014a, 2014b) identified the identified the presence of six significant ecological communities within or adjacent to the study areas. Significant ecological communities known to occur within the vicinity of the study areas are presented in Figure 6 and summarised in Table 7.

The Rottnest Island Pine (Callitris preissii) and the Rottnest Island Tea Tree (Melaleuca lanceolata) Woodland is listed as a ‘Vulnerable’ TEC under State legislation (RIA 2014a). This community is described as a woodland and forest community dominated by Callitris preissii, Melaleuca lanceolata, Spyridium globulosum, Acanthocarpus preissii, Rhagodia baccata, Austrostipa flavescens and Trachymene pilosa (Gibson et al. 1994). Critical habitat for this community is the sandy soils on which the community occurs and the fresh superficial groundwater that helps to sustain key dominant trees (DPaW 2014).

The microbialites and microbial mats of coastal hypersaline lakes (Rottnest Island) PEC comprises various communities in various lake locations across the island, which differ in the make-up of their respective microbial mats. The communities are listed as Priority 1 PECs of State significance. The Government House Lake Microbial PEC is listed as a Priority 2 PEC of State significance (DBCA 2018a). Various benthic microbial communities or algal mats are the dominant primary producers in most of the coastal lakes. The biodiversity of these systems is significantly linked to a large variety of avian fauna including migratory birds. The microbial mats in the salt lakes of Rottnest Island are dominated by cyano-bacteria and diatoms. The microbial communities in Rottnest Island salt lakes reflect the water quality, nutrient status and the interactions between biota and the physicochemical environment (John et al. 2017).

Coastal shrublands on shallow sands, southern Swan Coastal Plain (‘community type 29a’) is listed as a State-significance Priority 3 PEC and comprises mostly heaths on shallow sands over limestone close to the coast. Dominant and important species of the ecological community include Spyridium globulosum, Rhagodia baccata and Olearia axillaris (DBCA 2018a).

The Subtropical and Temperate Coastal Saltmarsh ecological community was listed as a Vulnerable TEC at a Federal level, under the EPBC Act, on 10 August 2013. The ecological community is listed a Priority 3 PEC by DBCA. This ecological community consists of an assemblage of plants, animals and micro-organisms associated with saltmarsh in coastal regions of sub-tropical and temperate Australia (south of 23°S latitude). The habitat is coastal areas under tidal influence. The community consists mainly of salt-tolerant vegetation (halophytes) including: grasses, herbs, reeds, sedges and shrubs. Succulent herbs and grasses generally dominate and vegetation is generally <0.5m tall with the exception of some reeds and sedges. Many species of non-vascular plants are also found in saltmarsh, including epiphytic algae, diatoms and cyanobacterial mats. This saltmarsh consists of many vascular plant species but is dominated by relatively few families. There is also typically a high degree of endemism at the species level. The two most widely represented coastal saltmarsh plant families are the Chenopodiaceae and Poaceae (DBCA 2019c). Four structural saltmarsh forms are currently recognised based on dominance of a particular vegetation type:

dominance by succulent shrubs (e.g. Tecticornia) dominance by grasses (e.g. Sporobolus virginicus) dominance by sedges and grasses (e.g. Juncus kraussii, Gahnia trifida) dominance by herbs (e.g. low-growing creeping plants such as Wilsonia backhousei, Samolus repens,

Schoenus nitens).

Although significantly degraded or modified patches of the Subtropical and Temperate Coastal Saltmarsh ecological community may not be protected as the ecological community listed under the EPBC Act, it is recognised that patches that do not meet the condition thresholds may still retain important natural values. Therefore, these patches should not be excluded from recovery and other management actions (Threatened Species Scientific Committee 2013).

The Banksia Woodlands of the Swan Coastal Plain Ecological Community (Banksia Woodland TEC) is a TEC of Commonwealth and State significance. It is largely restricted to the Swan Coastal Plain IBRA bioregion, within the Perth (SWA02) and Dandaragan (SWA01) sub-regions. It extends into the adjacent Jarrah Forrest IBRA region (JA01 and JA02 sub-regions) and areas of the Whicher and Darling escarpments where pockets of Banksia woodland may occur. This TEC mainly occurs on deep Bassendean and Spearwood sands or occasionally on Quindalup sands at the eastern edge (Threatened Species Scientific Committee 2016).

5.2 FIELD ASSESSMENT

5.2.1 Flora

A total of 49 flora species, from 41 genera and 26 families were recorded during the survey from three quadrats and four relevés. The dominant families were found to be Myrtaceae (seven species), Poaceae (seven species) and Cyperaceae (five species). The total includes 32 (65.3%) native species and 17 (34.7%) introduced (weed) species. The full list of vascular flora recorded is presented in Appendices C and D. Individual quadrat and relevé data are presented in Appendix E.

None of the recorded flora species are of conservation significance, listed as either Threatened flora under the State WC Act, nor the Commonwealth EPBC Act, or are Priority Flora listed by DBCA.


None of the recorded flora are exhibiting an extension beyond their currently documented range, in accordance with records of the Western Australian Herbarium (DBCA 2019b).

One of the recorded introduced (weed) species, Moraea flaccida (One Leaf Cape Tulip) is listed as a Declared Pest plant under the BAM Act within the district of the study area (DPIRD 2019a).

5.2.2 Vegetation

Eight intact or remnant native vegetation units were defined to occur within the study area, comprising of three woodlands, one shrubland, one sedgeland and one heath. Two of the woodland vegetation units (AhW and TW) are considered highly modified, due to the presence of a largely planted overstorey (i.e. Eucalyptus gomphocephala, Allocasuarina huegeliana and Agonis flexuosa which are not endemic to Rottnest Island). However, these vegetation units are included as part of the intact or remnant native vegetation units, as they support some endemic species, support flora species native to nearby ecosystems on the mainland and provide habitats typical of endemic vegetation.

An additional six planted areas were also defined as summarised in Table 8. The spatial extent of each of the mapped vegetation units is presented in the Figure 7 series.

5.2.3 Vegetation Condition

The vegetation condition of the study areas was found to range from ‘Completely Degraded’ (CD) to ‘Very Good’ VG), with most areas found to be in ‘Degraded – Completely Degraded’ (D-CD) condition across both the sites (Table 9).

The vegetation condition of the Garden Lake site was in considerably poorer condition, with 72.46% of the vegetation found to be ‘Completely Degraded’ (CD). Only 1.28% of vegetation was recorded to be in ‘Degraded – Good’ (D-G) condition, the highest rating for the Garden Lake site.

The vegetation condition at the Bickley site was found to be in better quality, ranging from ‘Very Good’ (VG) to ‘Completely Degraded’(CD).

5.2.4 Threatened and Priority Ecological Communities

A review of the DBCA Threatened and Priority Ecological Communities (TEC and PEC) database, interrogation of the EPBC Protected Matters Search Tool, a review of information provided by the RIA and other documents prepared by RIA (2014a, 2014b) identified the presence of six significant ecological communities within or adjacent to the study areas. These are:

FCT (SCP – Swan Coastal Plain) 30a – Callitris preissii (or Melaleuca lanceolata) Forests and Woodlands FCT (SCP) 29a - Coastal shrublands on shallow sands Microbialites and microbial mats of coastal hypersaline lakes (Rottnest Island), comprising:

o Lake community 1 - Serpentine Lake o Community 2 - Lake Timperley o Lake community 3 - Lake Vincent o Community 5 - Garden Lake o Community 6 - Herschel Lake o Lake Baghdad

Government House Lake Microbial Subtropical and Temperate Coastal Saltmarsh Ecological Community Banksia Woodlands of the Swan Coastal Plain IBRA Region.

None of the terrestrial vegetation units defined within the study areas are considered representative of any of the microbial PECs, SCP 29a or the Banksia Woodland TEC.

It is considered that one vegetation unit (MlArS) is representative of the ‘Vulnerable’ Callitris preissii (or Melaleuca lanceolata) Forests and Woodlands TEC (FCT 30a), based on dominant flora characteristics.

In order to test FCT affinities to FCT 30a, a simple comparative analysis of present flora species data was carried out for collected quadrat data in comparison to the consolidated Gibson et al. (1994) dataset. A summary of the results of this analysis is presented in Table 10, which supports the inference that the vegetation unit (MlArS) has an affinity to FCT 30a.

It is considered that one vegetation unit (TiSS) is representative of the ‘Vulnerable’ Subtropical and Temperate Coastal Saltmarsh ecological community, based the presence of all of the key diagnostic characteristics for describing the community at the mapped area at Garden Lake, which are as follows (Threatened Species Scientific Committee 2013):

occurs south of 23° 37' S latitude occurs on the coastal margin, along estuaries and coastal embayments and on low wave energy coasts occurs on places with at least some tidal connection, including rarely-inundated supratidal areas,

intermittently opened or closed lagoons, and groundwater tidal influences, but not areas receiving only aerosol spray

occurs on sandy or muddy substrate and may include coastal clay pans (and the like)


consists of dense to patchy areas of characteristic coastal saltmarsh plant species (i.e. salt-tolerant herbs, succulent shrubs or grasses, that may also include bare sediment as part of the mosaic)

proportional cover by tree canopy such as mangroves, Melaleucas or Casuarinas is not greater than 50%, nor is proportional ground cover by seagrass greater than 50%.

The occurrence of the vegetation unit, TiSS at Garden Lake also recorded dominance of some of the species typical of the ecological community, including Tecticornia spp., Gahnia trifida and Samolus repens.

Furthermore, DBCA’s Val English has identified the salt lake vegetation on Rottnest Island as being representative of this ecological community, although not yet mapped for inclusion in the MNES search tool (Cassyanna Gray, DBCA, pers. comm.).


6. DISCUSSION

6.1 FLORA

A total of 49 flora species, from 41 genera and 26 families were recorded during the survey from three quadrats and four relevés. The total includes 32 (65.3%) native species and 17 (34.7%) introduced (weed) species. The large proportion of weeds can be attributed to the close proximity of the study area to existing roads and infrastructure as well as to the settlement area.

The native floral diversity across the two sites is considered low (32 species), which is largely due to historic clearing, development and other disturbances associated with the Rottnest Island settlement.

None of the recorded flora species are of conservation significance, listed as either Threatened flora under the State WC Act, nor the Commonwealth EPBC Act, or as Priority flora listed by DBCA.

None of the recorded flora are exhibiting an extension beyond their currently documented range, in accordance with records of the Western Australian Herbarium (DBCA 2019b).

One of the recorded introduced (weed) species, Moraea flaccida (One Leaf Cape Tulip) is listed as a Declared Pest plant under the BAM Act within the district of the study area (DPIRD 2019a). This species was recorded within two vegetation units (GtS and ApH) at the Bickley site, adjacent to the airport. One Leaf Cape Tulip is a toxic, perennial weed, originally introduced as a garden plant in the 19th century and is spread by seed and the movement of corms (DPIRD 2019b). One Leaf Cape Tulip is listed as a Declared Plant under Section 22 of the Act, however, it is currently exempt from specific management control (DPIRD 2019a).

6.2 VEGETATION

Six vegetation units were defined and mapped within the study area from three quadrats and four relevés. The number of quadrats and relevés sampled was limited due to the highly modified and degraded nature of the study area. However, it is considered that the suite of intact and remnant vegetation units has been well-sampled by the number of detailed data collection points sampled.

Of the eight mapped vegetation units, only one, MlArS, was found to support vegetation in ‘Good’ or better condition, and could be considered intact. The remaining vegetation units were defined by relevés, as they retain too few floristic values to warrant quadrat sampling. These areas are considered remnant native vegetation, but not intact due to degradation.

Two of the woodland vegetation units (AhW and TW) that were described and mapped within the study areas are highly modified, with overstoreys that are largely planted, comprising Eucalyptus gomphocephala, Allocasuarina huegeliana and Agonis flexuosa. Such species are not endemic to Rottnest Island. However, these vegetation units are included as intact or remnant native vegetation units for the study, as they support some endemic species, support flora species native to nearby ecosystems on the mainland and provide habitats typical of endemic vegetation. This is in contrast to the planted areas which support predominantly cultivated garden species.

Six planted areas were defined. Each of these areas of various combinations of planted species primarily consisted of non-endemic species (cultivars such as palms and Oleander), often over introduced grasses and other weed species. Such areas were not defined by relevés, nor are they represented in species lists, since the ecological values supported are negligible, and therefore they are not relevant to a flora and vegetation assessment. The island has many introduced (non-native) species growing in the main settlement and along roads and pathways (RIA 2019).


The vegetation condition of the study areas was found to range from ‘Completely Degraded’ (CD) to ‘Very Good’ (VG). The vegetation condition of the Garden Lake site was in considerably poorer condition with 72.46% of the vegetation found to be in ‘Completely Degraded’ condition. Only 1.28% of vegetation was found to be in ‘Degraded – Good’ condition, the highest rating recorded for the Garden Lake site. The vegetation condition at the Bickley site is of better quality and ranges from ‘Very Good’ (VG) to ‘Completely Degraded’ (CD).

The Rottnest Island settlement area is a highly modified habitat, due to human impact and ongoing development (RIA 2019). The Garden Lake and Bickley sites have both been subject to a high level of disturbance such as access tracks, development and clearing. The Bickley site also occurs directly adjacent to the Rottnest Island airport.

A review of the DBCA TEC and PEC database, interrogation of the EPBC Protected Matters Search Tool (Appendix B) and an information and literature review of various material and documents provided and prepared by RIA (2014a, 2014b) identified the presence of six significant ecological communities within or adjacent to the study areas. These significant ecological communities four PECs of State-significance; SCP 30a, SCP 29a and two microbial mat communities (including various sub-types); the Subtropical and Temperate Coastal Saltmarsh ecological community and the Banksia Woodland TEC.

None of the recorded vegetation units are considered to be equivalent to the Banksia Woodland TEC or SCP 29a, based on species composition and habitat.

None of the terrestrial vegetation units described and mapped within the study areas are representative of any microbial mat ecological community. These communities exist within the salt lakes. The vegetation fringing Garden Lake would be considered to be associated with the microbialites and microbial mats of coastal hypersaline lakes (Rottnest Island), Community 5 - Garden Lake PEC, which occurs adjacently. Therefore, any direct impacts on this adjacent vegetation could result in indirect impacts on the fragile microbial community.

One vegetation unit (TiSS, mapped at Garden Lake) is considered representative of the ‘Vulnerable’ Subtropical and Temperate Coastal Saltmarsh ecological community, based positive results for six all of the key diagnostic characteristics for describing the community. This occurrence of the significant ecological community spans much of the lake fringe within the Garden Lake study area. This vegetation was mapped as mostly ‘degraded to completely degraded’, but with a small section of the Garden Lake fringe in ‘degraded to good’ condition.

One vegetation unit (MlArS) is inferred to be equivalent to the ‘Vulnerable’ Callitris preissii (or Melaleuca lanceolata) Forests and Woodlands TEC, based on dominant flora characteristics. This vegetation unit comprises of 36.42% of the two combined study areas. Within the Garden Lake site, it makes up 35.45% and at the Bickley site it comprises 27.20%. Within the Bickley site, only a small portion of the defined vegetation unit, adjacent to Parker Point Road and south of the track leading to the train shed, is considered to be in ‘Good’ or better condition. The remainder has been mapped as ‘Degraded – Good’ or ‘Degraded – Completely Degraded’.

Although very degraded/modified patches are generally not protected as significant ecological communities, Conservation Advice (Threatened Species Scientific Committee 2013; 2016) recognises that patches that do not meet the condition thresholds may still retain important natural values and may be critical to protecting the patches that do meed minimum condition threshold levels, Such a philosophy is also applicable to other representations of significant ecological communities, such as the occurrences of the Subtropical and Temperate Coastal Saltmarsh ecological community and SCP 30a.


7. CONCLUS IONS

The key findings and conclusions arising from the flora and vegetation assessment within the study area are as follows:

No flora species listed as Threatened or Priority under the WC Act or under the EPBC Act were recorded. Six intact or remnant vegetation units were described and mapped for the study area, comprising of three

Woodlands, one Shrubland, one Sedgeland and one Heath. One vegetation unit (TiSS) is considered to be representative of the ‘Vulnerable’ Subtropical and

Temperate Coastal Saltmarsh ecological community. Where possible, direct impacts from clearing or indirect impacts that may influence hydrological regimes applicable to this ecological community should be minimised or avoided.

One vegetation unit (MlArS) is considered to be equivalent to known State listed TEC, SCP 30a – Callitris preissii (or Melaleuca lanceolata) Forests and Woodlands. Where possible, clearing of this vegetation unit should be minimised or avoided.

One Declared Pest plant listed under the Biosecurity and Agriculture Management Act 2007 (BAM Act) (One Leaf Cap Tulip) was recorded within two vegetation units (GtS and ApH) at the Bickley site, adjacent to the airport. One Leaf Cape Tulip is listed as a Declared Plant under Section 22 of Act, however, it is currently exempt from specific management control.

- non-threatened seabirds which have only been mapped for recorded breeding sites

- migratory species that are very widespread, vagrant, or only occur in small numbers

- some species and ecological communities that have only recently been listed

Not all species listed under the EPBC Act have been mapped (see below) and therefore a report is a general guide only. Where available datasupports mapping, the type of presence that can be determined from the data is indicated in general terms. People using this information in makinga referral may need to consider the qualifications below and may need to seek and consider other information sources.

For threatened ecological communities where the distribution is well known, maps are derived from recovery plans, State vegetation maps, remotesensing imagery and other sources. Where threatened ecological community distributions are less well known, existing vegetation maps and pointlocation data are used to produce indicative distribution maps.

- seals which have only been mapped for breeding sites near the Australian continent

Such breeding sites may be important for the protection of the Commonwealth Marine environment.

Threatened, migratory and marine species distributions have been derived through a variety of methods. Where distributions are well known and iftime permits, maps are derived using either thematic spatial data (i.e. vegetation, soils, geology, elevation, aspect, terrain, etc) together with pointlocations and described habitat; or environmental modelling (MAXENT or BIOCLIM habitat modelling) using point locations and environmental datalayers.

The information presented in this report has been provided by a range of data sources as acknowledged at the end of the report.Caveat

This report is designed to assist in identifying the locations of places which may be relevant in determining obligations under the EnvironmentProtection and Biodiversity Conservation Act 1999. It holds mapped locations of World and National Heritage properties, Wetlands of Internationaland National Importance, Commonwealth and State/Territory reserves, listed threatened, migratory and marine species and listed threatenedecological communities. Mapping of Commonwealth land is not complete at this stage. Maps have been collated from a range of sources at variousresolutions.

- threatened species listed as extinct or considered as vagrants

- some terrestrial species that overfly the Commonwealth marine area

The following groups have been mapped, but may not cover the complete distribution of the species:

Only selected species covered by the following provisions of the EPBC Act have been mapped:

Where very little information is available for species or large number of maps are required in a short time-frame, maps are derived either from 0.04or 0.02 decimal degree cells; by an automated process using polygon capture techniques (static two kilometre grid cells, alpha-hull and convex hull);or captured manually or by using topographic features (national park boundaries, islands, etc). In the early stages of the distribution mappingprocess (1999-early 2000s) distributions were defined by degree blocks, 100K or 250K map sheets to rapidly create distribution maps. More reliabledistribution mapping methods are used to update these distributions as time permits.
