EXECUTIVE SUMMARY Lynas Kalgoorlie Pty Ltd (Lynas) commissioned Onshore Environmental Consultants (Onshore Environmental) to undertake a detailed flora and vegetation survey of Lot 500 Great Eastern Highway, Yilkari (herein referred to as the study area) (Figure 1). The study area covers 134.92 hectares (ha) and is situated approximately 9 km southwest of Kalgoorlie in the Goldfields region of Western Australia. Rare earth concentrate from the Mt Weld mine near Laverton will undergo a cracking and leaching process at the Kalgoorlie Rare Earths Recovery Project.
The flora and vegetation survey was completed under fair seasonal conditions between the 20th and 24th of November 2019 by a Principal Botanist with over 15 years’ experience working in the bioregion.
A total number of 104 plant taxa (including varieties and subspecies) from 25 families and 51 genera were recorded from the study area. Species representation was greatest among the Chenopodiaceae, Poaceae, Scrophulariaceae, Fabaceae, Myrtaceae and Asteraceae families. The most speciose genus was Eremophila (12 taxa) followed by Eucalyptus and Maireana (9 taxa), Acacia (5 taxa), Atriplex and Sclerolaena (4 taxa).
None of the plant taxa recorded from the study area were gazetted as Threatened Flora pursuant to the Biodiversity Conservation Act 2016 (BC Act), or listed under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). There were no Priority flora taxa, as listed by the Department of Biodiversity Conservation and Attractions (DBCA), recorded from the study area, and none of the plant taxa recorded were considered to represent a significant range extension from their current known distributions.
Eight introduced species were recorded by Onshore Environmental at November 2019, with an additional two weed species recorded during a previous reconnaissance flora and vegetation survey of Lot 500 in June 2018. None of these ten introduced species recorded from the study area are listed as Declared Pests under the Biosecurity and Agriculture Management Act 2007 (BAM Act 2007).
A total of seven vegetation associations classified as six broad floristic formations and occurring on four broad landforms were described and mapped from the study area. None of the vegetation associations were aligned with any federal or state listed Threatened Ecological Communities (TECs) or state listed Priority Ecological Communities (PECs) documented from the Coolgardie bioregion.
Vegetation within the study area was determined to be well represented at all levels (statewide, bioregional [IBRA region and IBRA sub-region] and local), with greater than 96.2% of the pre-European extent remaining for the one Beard (1978) vegetation association represented. The proportion of the same vegetation association occurring within secure (Class I-IV) reserves ranged from 8.1% to 11.3% at the state level, bioregional and local levels, which is under the 15% minimum standard. However, given that the proposed development will not significantly reduce the pre-European extent of the Beard vegetation association represented (i.e. it will remain well above the 30% threshold within the bioregion), the reservation status is determined to be of least concern for biodiversity conservation.

Vegetation condition within the study area was predominantly rated as very good (130.8 ha or 97%), with small areas along the boundary of the lot rated as good (4.0 ha or 3%). Disturbances included edge effects along roads and access tracks, historic ground disturbance activities, rubbish dumping, mine exploration, sandalwood cutting, timber cutting, historical revegetation, grazing by rabbits, motorbike tracks and unauthorised camping activities.

1.0 INTRODUCTION 1.1 Preamble In May 2019, Lynas announced the Lynas 2025 Growth Strategy to meet growing demand for rare earths. The key component of the strategy was a new cracking and leaching plant based in Western Australia to include a 50 percent increase in current capacity, while continuing to feed the existing Malaysian based plant. The new plant will treat rare earth concentrate from the Mt Weld mine near Laverton.
As part of required approvals for the new cracking and leaching plant, Onshore Environmental was commissioned to undertake a detailed flora and vegetation survey of Lot 500 Great Eastern Highway, Yilkari (herein referred to as the study area) (Figure 1). It is proposed that the Kalgoorlie Rare Earths Recovery Project will be constructed on Lot 500. The study area covers 134.92 ha (1.35 km2) and is situated approximately 9 km southwest of Kalgoorlie in the Goldfields region of Western Australia.
The field survey was completed by a Principal Botanist from Onshore Environmental between the 20th and 24th of November 2019.
1.2 Land Use The dominant land uses surrounding urban development forming the City of Kalgoorlie-Boulder are grazing of rangelands, crown reserves and mining. Kalgoorlie is the main regional urban and industrial centre within the region. Mining occurs immediately adjacent to Kalgoorlie, Coolgardie and many of the small towns in the Goldfields, with numerous small abandoned mines and open shafts across the landscape. The study area is a greenfield site, historically and currently undeveloped and unoccupied, and zoned ‘Future Industry’.
1.3 Biogeographic Regions The latest version of the Interim Biogeographic Regionalisation for Australia (IBRA7) divides Australia into 89 bioregions based on climate, geology, landform, native vegetation and species information, and includes 419 sub-regions (Department of Environment 2013). The bioregions and sub-regions are the reporting unit for assessing the status of native ecosystems and their level of protection in the National Reserve System.
The study area is located within the Eastern Goldfields sub-region (COO003) of the Coolgardie bioregion, which covers over 5.1 million hectares (CALM, 2002). The Eastern Goldfields sub-region comprises vegetation dominated by Mallees, Acacia thickets and shrub heaths on sandplains, diverse Eucalyptus woodlands around salt lakes, on ranges, and in valleys, while salt lakes support dwarf shrublands of samphire. Woodlands and Dodonaea shrubland occur on basic graninulites of the Fraser Range. The subregion is rich in endemic Acacias (CALM, 2002).

1.4 Climate The Kalgoorlie region has an arid to semi-arid climate. The closest weather station to the study area is the Kalgoorlie-Boulder Airport station, approximately 7 km east of the study area. Average annual rainfall is 267 mm. The rainfall pattern is bimodal with a peak in February and another smaller peak in June. Summer rainfall originates from deteriorating tropical cyclones that cross the coast of northern Western Australia and dissipate to the south east. Winter rainfall results from cold fronts crossing the southern coastline and moving inland. Mean maximum summer temperatures peak at 33 degrees with mean minimum winter temperatures down to 5 degrees.
In 2019 above average monthly rainfall occurred in April and July, with the remaining months through to the November field survey recording below average falls (Figure 2). A total of 27 mm was received during the four months prior to the field survey, compared to the long term average of 75 mm for the same period. Seasonal conditions at the time of the field survey was rated as ‘fair’.
Figure 2 Rainfall and climatic data recorded at the Kalgoorlie-Boulder Airport station (12038) for 2019, with long term average (Bureau of Meteorology 2019).
1.5 Soils Tille (2007) classified the most recent and detailed mapping of Western Australia’s rangelands and arid interior into a hierarchy of soil-landscape mapping units. The study area is located within the Kalgoorlie Province, which has been divided into six soil-landscape zones.
The Kambalda Zone overlies the greenstone of the Eastern Goldfields and Southern Cross Granite-Greenstone Terrane tectonic units of Tyler and Hocking (2001). It lies

within the Salinaland and Coonana-Ragged Plateau Sections of Jennings and Mabbutt (1977) and is differentiated from the Norseman Zone due to the preponderance of the stony plains with acacia shrublands and halophytic shrublands, low hills with eucalypt or acacia woodlands with halophytic undershrubs, stony plains with acacia shrublands and alluvial plains with eucalypt woodlands and halophytic undershrubs rangeland land types (Pringle 1994).
The zone comprises flat to undulating plains (with hills, ranges and some salt lakes and stony plains) on greenstone and granitic rocks of the Yilgarn Craton. Soils were mapped as unit Mx43 – brown deep loamy duplex. More specifically, the surface horizon (0-75 mm) was described as brown sandy loam with abundant ferruginous segregations and a few quartz medium gravel sized coarse fragments, with the lower horizon (75-125 mm) described as yellow sandy medium clay.
1.6 Landforms The Kalgoorlie Province consists of an extensive plateau of low relief; flat to undulating plains with small valleys (occasionally broken by low narrow rocky hills, ridges, tors and bosses) are most commonly found on granitic terrain. These plains support silcrete duricrust, claypans, salt lakes with dunes and lunettes, gilgai areas, small remnants of sand plain, and small dune tracts. Low breakaways with short saline footslopes are also occasionally present. Below these plains are some broad, flat to undulating, shallow valley plains formed on Quaternary alluvium and colluvium. These plains show little defined drainage and some seasonal lakes and claypans with isolated granitic and basic rock outcrops. Slightly lower down in the landscape are broad, flat valleys with chains of salt lakes. Also present on these valley floors are saline flats, claypans, kopi dunes, sand dunes, and sometimes tors and bosses of outcropping granites. Higher up in the landscape are gently sloping to gently undulating plateau areas on granites and gneisses. These have long gentle slopes and, in places, abrupt erosional scarps. Some granitic bosses and tors are present. Rocky ranges, hills and ridges have formed on the greenstone, along with some undulating to low hilly country. Associated with this hilly terrain are gently undulating stony plains and low rises on limonite. Level to gently undulating sandplains and gravelly sandplains are mostly found over lateritic residuals and granitic basement. There are also some extensive loamy plains with sandy surfaces.
The study area is topographically flat to undulating, set on predominantly a red loam over a clay base soil type.
1.7 Flora and Vegetation The study area is located within the Austin Botanical District, within the Coolgardie IBRA region of the South-western Interzone (Beard 1990). Beard (1978) described and mapped vegetation of the Kalgoorlie area at 1:250 000, differentiating eight vegetation systems. The original vegetation mapping undertaken by Beard (1978) was refined by Shepherd et al. (2002), who defined one vegetation association covering the study area (Figure 3). The Pre-European extent currently remaining for Vegetation association 9 is 97.78%, with 1.56% of the current extent protected within Class I-IV conservation reserves (Table 1).

2.0 METHODOLOGY 2.1 Legislation and Guidance Statements The detailed flora and vegetation survey was carried out in a manner that was compliant with Environmental Protection Authority (EPA) requirements for the environmental surveying and reporting of flora and vegetation in Western Australia:
Technical Guidance Flora and Vegetation Surveys for Environmental Impact Assessment (EPA 2016a); and
Environmental Factor Guideline: Flora and Vegetation (EPA 2016b).
2.2 Desktop Assessment
2.2.1 Literature Review Regional scale reports relevant to the study area locality were reviewed, including:
a summary of bioregional data (Cowen 2001); and vegetation description and mapping by Beard (1976).
In addition, there was a recent reconnaissance flora and vegetation survey undertaken at Lot 500 Great Eastern Highway on behalf of the City of Kalgoorlie on the 13th June 2018 (Native Vegetation Solutions 2018).
2.2.2 Database Searches Desktop searches included databases relating to significant flora, TECs and PECs previously collected or described within, or in close proximity to, the study area. For this report the search was extended beyond the study area to place flora values into a local and regional context. The following databases were searched:
NatureMap1: This database represents the most comprehensive source of information on the distribution of Western Australia’s flora, comprising records from the Department of Biodiversity, Conservation and Attractions (DBCA) Threatened Flora database and the WA Herbarium Specimen Database (50 km radial search) (DBCA 2020);
DBCA’s Threatened and Priority flora database was searched to confirm the NatureMap results (50 km radial search) (DBCA 2018a);
DBCA’s TEC, PEC and Environmentally Sensitive Areas (ESAs) database was searched to identify significant communities (50 km radial search) (DBCA 2018b);
EPBC Act Protected Matters database (10 km radial search) (DoEE 2020); and
International Union for Conservation of Nature (IUCN) database) (IUCN 2020).
2.2.3 Assessment of Likelihood of Occurrence in the Study Area A list of conservation significant species occurring within a 50 km radius of the study area was compiled during the desktop searches. The likelihood of each taxon occurring within the study area was assessed using a set of rankings and criteria (Table 2) based on presence of suitable landform (inferred from aerial imagery with contours overlayed and from knowledge of the adjacent areas) and distance to known records.

Table 2 Ranking system used to assign the likelihood that a species would occur in the study area.
Rank Criteria
Recorded The species has been recorded in the study area.
Likely to occur The species has previously been recorded from a landform which is present within the study area, and there are previous records within a 10 km radius of the study area.
Possible to occur The species has previously been recorded from a landform which is present within the study area, and there are previous records within a 10-50 km radius of the study area.
Unlikely to occur The landform from which the species has previously been recorded is absent within the study area, and/or there are no previous records within a 50 km radius of the study area.
2.2.4 Assessment of Conservation Significance The conservation significance of flora and ecological communities are classified at a Commonwealth, State and Local level on the basis of various Acts and Agreements, including: International Level:
IUCN: The IUCN ‘Red List’ lists species at risk under nine categories (status codes) (Appendix 1).
Commonwealth Level: EPBC Act: The DoEE lists Threatened flora and ecological communities,
which are determined by the Threatened Species Scientific Committee according to criteria set out in the Act. The Act lists flora that are considered to be of conservation significance under one of six categories (Appendix 1).
State Level: BC Act: At a State level, native flora species are protected under the BC Act
– Wildlife Conservation Notice. A number of species are assigned an additional level of conservation significance based on a limited number of known populations and the perceived threats to these locations (Appendix 1); and
DBCA Priority list: DBCA produces a list of Priority species and ecological communities that have not been assigned statutory protection under the WC Act. Possibly threatened species that do not meet survey criteria, or are otherwise data deficient, are added under Priorities 1, 2 or 3. Species that are adequately known, are rare but not threatened, or meet criteria for near threatened, or that have been removed from the threatened species list for other taxonomic reasons, are placed in Priority 4. These species require regular monitoring (see Appendix 1). The list of PECs identifies those that need further investigation before nomination for TEC status at a State level.
Local Level: Species may be considered of local conservation significance because of
their patterns of distribution and abundance. Although not formally protected by legislation, such species are acknowledged to be in decline as a result of threatening processes, primarily habitat loss through land clearing.

2.3 Survey Methodology
2.3.1 Timing and Personnel The flora and vegetation survey was completed by Principal Botanist Dr Jerome Bull working between the 20th and 24th of November 2019. The field botanist has 15 years’ experience working in the Goldfields region.
2.3.2 Sampling of Study Sites The field survey involved systematic sampling using quadrats (referred to as study sites). Relevé vegetation descriptions were made to increase the accuracy of vegetation mapping and targeted searches were completed in habitats where it was anticipated that significant flora might occur. The study sites were 20 m by 20 m in dimension which is standard for the Coolgardie bioregion. The number of study sites sampled was determined by the size and heterogeneity of the study area, and confirmed by a species accumulation curve (Figure 4). A total of 16 quadrats were formally assessed. The locations of all quadrats sampled are provided in Figure 5.

The sampling sites were assessed to provide a list of the total flora occurring within the study area and a description of the vegetation structure. Data collected covered a range of environmental parameters including:
Landform and habitat; Aspect; Soil colour and soil type; Rock type; Slope (angle); Vegetation condition; Disturbance (caused by fire, clearing, grazing etc.); Age since fire; Broad floristic formation; Vegetation association description; and Height and percentage ground cover provided by individual plant taxa.
Other parameters recorded for each study site were: Study site number and date of assessment; Names of the botanists undertaking the assessment; Location description a waypoint – GPS coordinate (GDA94) using a handheld
GPS; and Photograph number.
Vegetation condition for each of the study sites was determined using a recognised rating scale (based on Keighery 1994, see Appendix 2).
2.3.3 Targeted Surveys for Conservation Significant Species Targeted searches for species of conservation significance were completed within the study area. Ground truthing provided an opportunity to record opportunistic locations for Threatened and Priority listed flora and undertake closer examination of specific landforms where conservation significant flora would be expected to occur.
2.3.4 Weed Survey and Mapping Introduced species were recorded from the study sites assessed within the study area. Opportunistic collections were also made while moving throughout the study area, with targeted weed searches completed in high moisture habitats.
2.3.5 Floristic Analysis A multivariate statistical analysis of the floristic quadrat data (16 quadrats) was completed to assist in understanding the vegetation-habitat relationships within the study area. Statistical analysis of quadrat data can support delineation of vegetation associations within the study area, and provide comparison against locally significant communities (TECs and PECs) where quadrat data is available.
A two-way classification (Agglomerative Hierarchical Fusion) of the presence/absence quadrat data was carried out on the 81 taxa x 16 quadrat dataset using the program PATN (Belbin 2003). The flexible unweighted pair group method with arithmetic mean (UPGMA) classification strategy was used (β = -0.1), together with the Bray-Curtis site similarity measure. The number of groups to be determined was set at seven. The primary output of the classification was in the form of a dendrogram (Appendix 3).

The results from the statistical analysis need to be appropriately analysed by an experienced botanist, and effects such as fire disturbance, ephemeral taxa, and spatial distribution of quadrats taken into consideration when interpreting the results. Plant taxa that occupy a range of vegetation types can obscure vegetation patterning and influence statistical outputs. It must be acknowledged that the results of multivariate statistical analysis may not always align with the delineated vegetation associations; in these insistences an explanation for the differences will be provided.
2.3.6 Vegetation Association Mapping The classification of vegetation associations within the study area follow the height, life form and density classes of Specht (1970) as modified by Aplin (1979) and Trudgen (2009) (see Appendix 4). This is largely a structural classification suitable for broader scale mapping, but taking all ecologically significant strata into account.
The description of vegetation associations lead with the most dominant strata (based on percent cover) and flora species listed start with the most dominant (Table 3). Table 4 further describes and categorises these strata and gives examples of potential growth forms for each, e.g. over-storey (U), mid-storey (M) and under-storey (G) vegetation strata.
Vegetation associations recorded within the study area are grouped according to ‘broad floristic formation’ (refer to Table 3). A broad floristic formation describes the dominant growth form, cover and height as well as the dominant land cover genus for the dominant stratum (DEH 2003).
The vegetation mapping utilised high-resolution aerial photography of the entire study area at a scale of 1:12,500, with definition of vegetation polygons based on contrasting shading patterns. Ground-truthing of the study area was completed during the survey with vegetation descriptions made within selected vegetation polygons to confirm dominant structural layers and associated plant taxa. The 16 study sites and numerous relevé plots were overlaid on the aerial photography, and associated flora and vegetation data was used to provide vegetation association descriptions for individual polygons defined.
2.3.7 Vegetation Association Coding A vegetation association code is applied to each vegetation association. This code is comprised of the dominant landform on which the vegetation association occurs and the dominant plant taxa in each vegetation stratum.
2.3.8 Vouchering At least one voucher specimen was taken for each species collected to verify identification. Taxonomy was completed by Dr Jerome Bull at the Western Australian Herbarium (WAH) with use made of the WAH for confirmation of species identification.

2.3.9 Field Survey Constraints The EPA Technical Guidance for Flora and Vegetation Surveys for Environmental Impact Assessment in Western Australia (EPA 2016a) list seven potential limitations that field surveys may encounter. These limitations are addressed in Table 5.
Table 5 Relevance of limitations, as identified by EPA (2016a), to the flora and vegetation survey.
Constraint Relevance Availability of contextual information at a regional and local scale
A reconnaissance flora and vegetation survey was completed over half of the study area (Lot 500) in 2018 (Native Vegetation Solutions 2018), providing an excellent local database.
Proportion of flora recorded and/or collected, any identification issues
It is likely that a large proportion of the total flora occurring within the study area was recorded given the high intensity sampling completed for the field survey. The seasonal conditions at the time of survey were rated as fair, resulting in the species level identification of a small number of ephemeral taxa not being confirmed; these taxa did not include conservation significant flora.
Survey timing, rainfall, season of survey
The field survey was completed during the spring period in the Goldfields, as per recommendations made by EPA (2016). A total of 27 mm was received during the four months prior to the field survey, and seasonal conditions were rated as ‘fair’. Good flowering was observed during the survey, however some annual grass and herb species were in poor condition making identification difficult.
Disturbance that may have affected the results of the survey such as fire, flood or clearing
There were no disturbances recorded within the study area that influenced survey outcomes. Disturbances within the study area were restricted to access tracks and edge effects along the Great Eastern Highway. Disturbances did not impact on the ability to complete the field survey.
Was the appropriate area fully surveyed (effort and extent)
A Principal Botanist spent five field days covering the entire study area. A total of 16 quadrats supplemented by numerous relevé sites were assessed within the study area. This represented an extensive survey effort. The latest EPA technical guidelines (EPA 2016a) recommends that a minimum of three quadrats should be sampled in each vegetation unit. Three of the ten vegetation associations mapped within the study area have less than three quadrats due to the small size of these units; all of these units were thoroughly ground truthed to ensure comprehensive coverage was achieved.
Access restrictions within the survey area
The study area was accessed on foot, noting that vegetation mapping was facilitated by high-resolution aerial photography. Access did not pose any restrictions to undertaking the field survey.
Competency/experience of the team carrying out the survey, including experience in the bioregion surveyed
The Principal Botanist working on the survey (Dr Jerome Bull) has more than 15 years’ experience working in the region, and has completed a number of surveys in close proximity to the study area.

3.0 RESULTS 3.1 Desktop Review
3.1.1 Previous Baseline Flora Surveys In terms of its floristic richness, the Goldfields region includes species from both the south-west (Merchant, 1973; Hopper, 1979) and the arid interior, as well as numerous species which are either endemic to the Goldfields or have restricted geographic distributions. Broad scale vegetation mapping was first carried out by Gardener (1942) and later refined by Beard (1975). Early flora survey work was carried out by Willis (1959) and Beard (1979), but it was not until the Biological Survey of the Eastern Goldfields program conducted by the Biological Surveys Committee (BSC 1985) that any detailed flora surveys was conducted. This involved the study of vegetation and flora at 166 sites within the Jackson-Kalgoorlie region which lies within the Coolgardie Botanical District. The sites represented 52 broad vegetation types. The vascular flora comprised three species of fern, and 777 species, 16 subspecies and 20 varieties of flowering plants, a total of 816 taxa. Fifteen undescribed species were collected and a further 19 had been poorly collected previously. No Threatened Flora species were recorded although 18 taxa were considered to be confined to the area.
A reconnaissance flora and vegetation survey was undertaken on the 13th June 2018 at Lot 500 Great Eastern Highway, on behalf of the City of Kalgoorlie Boulder (Native Vegetation Solutions 2018). The field survey recorded total of 21 plant families, 38 genera and 77 species. There were no Commonwealth or State listed Threatened Flora, or Priority Flora taxa (as listed by DBCA) recorded from Lot 500. Three introduced species were recorded; Citrullus lanatus (Pie Melon), Salvia verbenaca (Wild Sage) and Cenchrus ciliaris (Buffel Grass). Six major vegetation groups were recorded, with none of these aligned to known TECs or PECs. Vegetation condition was predominantly rated as very good or good, with disturbance linked to historical mineral exploration and associated access tracks.
3.1.2 Threatened Flora listed under the EPBC Act A search of the EPBC Act Protected Matters database was undertaken for a 10 km radius around the study area (DoEE 2020). No Threatened Flora as listed under the EPBC Act have been recorded as occurring within the 50 km search radius for the study area.
3.1.3 Threatened Flora listed under the IUCN Red List A search of the International Union for Conservation of Nature (IUCN) database (IUCN 2020) determined that no Threatened Flora taxon was likely to occur within the study area.
3.1.4 Threatened Flora listed under the BC Act No Threatened Flora taxon were identified from the DBCA rare flora database search (DBCA 2018) as occurring within a 50 km radius of the study area.

3.1.5 Priority Flora recognised by the DBCA The DBCA rare flora database search (DBCA 2018a) identified 15 Priority flora taxa as potentially occurring within a 50 km radius of the study area (Table 6). Two of these taxa were considered ‘likely’ to occur within the study area (as per criteria set out in Table 2) based on occurrence of habitat and proximity of previous records (Table 6). It was considered ‘possible’ that seven taxa identified during the database searches may occur within the study area (Table 6).
3.1.6 TECs listed under State and Federal Legislation A search of the EPBC Act Protected Matters database (DoEE 2019) confirmed there were no federal listed TECs previously recorded within, or adjacent to, the study area. Similarly, a search of the DBCA ecological community database (DBCA 2019b) confirmed there were no state listed TEC records for the immediate study area.
3.1.7 PECs recognised by DBCA A search of DBCA’s ecological community database (DBCA 2019) confirmed that no PECs were known to occur within a 50 km radius of the study area.

3.2 Flora Species A total number of 104 plant taxa (including varieties and subspecies) from 25 families and 51 genera were recorded from the study area (Table 7, Appendix 5). Species representation was greatest among the Chenopodiaceae, Poaceae, Scrophulariaceae, Fabaceae, Myrtaceae and Asteraceae families (Table 7). The most speciose genus was Eremophila (12 taxa) followed by Eucalyptus and Maireana (9 taxa), Acacia (5 taxa), Atriplex and Sclerolaena (4 taxa).
The most common species encountered across the study area were Pearl Bluebush (Maireana sedifolia), Currant Bush (Scaevola spinescens), Native Senna (Senna artemisioides subsp. filifolia), Goldfields Daisy (Olearia muelleri), Broom Bush (Eremophila scoparia), Tar Bush (Eremophila glabra subsp. glabra), Cotton Bush (Ptilotus obovatus), Bladder Saltbush (Atriplex vesicaria), Leafless Ballart (Exocarpos aphyllus) and Tan Wattle (Acacia hemiteles). The most common tree species encountered were the Goldfields Blackbutt (Eucalyptus lesouefii), Giant Mallee (Eucalyptus oleosa subsp. oleosa), Salmon Gum (Eucalyptus salmonophloia), Redwood (Eucalyptus transcontinentalis) and Griffith’s Grey Gum (Eucalyptus griffithsii).

3.3 Significant Flora
3.3.1 Threatened Flora listed under the BC Act and EPBC Act None of the plant taxa recorded from the study area were gazetted as Threatened Flora (T) under the EPBC Act or the BC Act.
3.3.2 Significant Flora None of the plant taxa recorded from the study area were determined to be Priority flora, as listed by the DBCA.
3.3.3 Range Extensions None of the plant taxa recorded from the study area was considered to represent a significant range extension from the current known distributions.
3.4 Introduced Flora A total of eight introduced species were recorded by Onshore Environmental from within the study area at November 2019 (Figure 6, Table 8). Two additional species, Cenchrus ciliaris and Citrullus lanatus, were recorded by Native Vegetation Solutions (2018) during a reconnaissance flora and vegetation survey of Lot 550 in June 2018. None of the ten introduced species recorded are listed as Declared Pests under the BAM Act 2007.
Most of the introduced species within the study area were recorded along road verges, drainage ditches, minor drainage lines and areas of historical ground disturbance including mine exploration, access tracks, road construction and/or areas of sandalwood cutting. Many of the weed species recorded have likely been introduced during early exploration and expansion into the area, becoming established on disturbed ground and dispersing into adjacent areas.
The diversity of introduced species recorded during the November 2019 survey was relatively low considering the close proximity to the Great Eastern Highway, the high number of internal access tracks, and the high level of historical ground disturbance. The low diversity likely reflects the timing of the field survey (mid November 2019) and dry spring conditions.

3.6 Vegetation A total of seven vegetation associations classified as six broad floristic formations and occurring on four broad landforms was described and mapped from the study area (Figure 8, Table 10). A species by site matrix and raw data for the 16 study sites is presented in Appendices 6 and 7 respectively.
The latest EPA technical guidelines (EPA 2016a) recommend that a minimum of three quadrats should be sampled in each vegetation unit. Due to the relatively small size of the study area and fine scale vegetation mapping completed, one vegetation association was sampled with two quadrats (Table 10); where less than three quadrats were assessed, the entire vegetation unit was intensively ground truthed to record new plant taxa and undertake targeted searches for significant flora taxa.
None of the vegetation associations described and mapped from the study area were found to be aligned with any TECs or PECs documented from the Coolgardie bioregion.
The vegetation of Lot 500 comprised Eucalyptus salmonophloia and Eucalyptus transcontinentalis dominated Woodlands in the western half, and Eucalyptus oleosa subsp. oleosa and Eucalyptus lesouefii dominated Tree Mallee in the eastern half. Interspersed were Eremophila, Senna and Acacia hemiteles-dominated Scrub on minor hardpan depressions, Open Shrub Mallee of Eucalyptus celastroides subsp. celastroides along minor drainage lines and flats, and Open Tree Mallee of Eucalyptus griffithsii on subdued sandy/stony rises and plains. A small but distinctive thicket of Acacia acuminata and Melaleuca hamata with a scattered overstorey of the shrub mallee Eucalyptus longissima occurred on a stony plain in the far north-east sector. This vegetation association did not occur elsewhere in the study area.

3.7 Representation and Reservation of Vegetation To assess the representation of vegetation within the study area, regional mapping completed by Beard (1978) was utilised. A single Beard vegetation association was represented within the study area (Table 11). In terms of representation, the Western Australian Government is committed to the National Objectives Targets for Biodiversity Conservation which includes a target that prevents clearance of ecological communities with an extent below 30% of that present pre-European settlement (Department of Natural Resources and Environment 2002, EPA 2000).
When considering representation at the State level, the Beard association represented within the study area currently has 97.8% of the pre-European extent remaining (Government of Western Australia 2018). The study area is located within the Coolgardie bioregion, specifically within the Eastern Goldfield subregion (as discussed in Section 1.3). When considering the representation of vegetation at the IBRA regional level and IBRA system level, 97.8% of the pre-European extent remains for the vegetation association represented (Table 11). The study area falls entirely within the City of Kalgoorlie-Boulder. At this local level 96.2% of the pre-European extent remains for the vegetation association represented (Table 11). Vegetation within the study area is therefore determined to be well represented at all levels (statewide, bioregional [IBRA region and IBRA sub-region] and local), with greater than 96.2% of the pre-European extent remaining for the Beard vegetation association represented.
In terms of reservation, there is a benchmark for a minimum of 15% of each Beard vegetation association to be protected in Class I-IV reserves (Commonwealth of Australia 1997). Across all levels, the proportion of the sole vegetation association occurring within secure reserves ranges from 8.1% to 11.3% at the state level, bioregional and local levels (Table 11). However, given that the proposed development will not significantly reduce the pre-European extent of the Beard vegetation association represented within the study area (i.e. will remain well above the 30% threshold within the bioregion), the reservation status is determined to be of least concern for biodiversity conservation.

3.8 Conservation Significance of Vegetation
3.8.1 National Significance None of the seven vegetation associations recorded from the study area support Threatened Flora listed under the EPBC Act, or are aligned with any federal listed TECs. Therefore vegetation within the study area is not considered to be of national significance.
3.8.2 State Significance None of the seven vegetation associations recorded from the study area support Threatened Flora listed under the BC Act or Priority flora listed by the DBCA, or are aligned with any state listed TECs or PECs. Therefore vegetation within the study area is not considered to be of state significance.
3.8.3 Local Significance None of the 104 plant taxa recorded within the study area were considered to represent significant range extensions from their current known distributions. Therefore, vegetation was determined not to be of local conservation significance.

4.0 SUMMARY The detailed flora and vegetation survey of Lot 500 Great Eastern Highway Yilkari, was completed under fair seasonal conditions in November 2019 by a Principal Botanist with over 15 years’ experience working in the region.
A total number of 104 plant taxa from 25 families and 51 genera was recorded from the study area. Species representation was greatest among the Chenopodiaceae, Poaceae, Scrophulariaceae, Fabaceae, Myrtaceae and Asteraceae families. The most speciose genus was Eremophila (12 taxa), followed by Eucalyptus and Maireana (9 taxa), Acacia (5 taxa), Atriplex and Sclerolaena (4 taxa).
None of the plant taxa recorded from the study area were gazetted as Threatened Flora pursuant to the BC Act, or listed under the EPBC Act. There were no Priority flora taxa, as listed by the DBCA, recorded from the study area, and none of the plant taxa recorded were considered to represent a significant range extension from their current known distributions.
Eight introduced species were recorded, with an additional two weed species recorded during a previous reconnaissance flora and vegetation survey of Lot 500 in June 2018. None of these ten introduced species recorded from the study area are listed as Declared Pests under the BAM Act 2007.
A total of seven vegetation associations classified as six broad floristic formations and occurring on four broad landforms were described and mapped from the study area. None of the vegetation associations were aligned with any federal or state listed TECs or state listed PECs documented from the Coolgardie bioregion.
Vegetation within the study area was determined to be well represented at all levels (statewide, bioregional [IBRA region and IBRA sub-region] and local), with greater than 96.2% of the pre-European extent remaining for the one Beard (1978) vegetation association represented. The proportion of the same vegetation association occurring within secure (Class I-IV) reserves ranged from 8.1% to 11.3% at the state level, bioregional and local levels, which is under the 15% minimum standard. However, given that the proposed development will not significantly reduce the pre-European extent of the Beard vegetation association represented (i.e. it will remain well above the 30% threshold within the bioregion), the reservation status is determined to be of least concern for biodiversity conservation.
Vegetation condition within the study area was predominantly rated as very good (130.8 ha or 97%), with small areas along the boundary of the lot rated as good (4.0 ha or 3%). Disturbances included edge effects along roads and access tracks, historic ground disturbance activities, rubbish dumping, mine exploration, sandalwood cutting, timber cutting, historical revegetation, grazing by rabbits, motorbike tracks and unauthorised camping activities.

Conservation categories for flora described under the EPBC Act
Category Description
Extinct (EX) A species is extinct if there is no reasonable doubt that the last member of the species has died.
Extinct in the Wild (EW)
A species is categorised as extinct in the wild if it is only known to survive in cultivations, in captivity, or as a naturalised population well outside its past range; or if it has not been recorded in its known/expected habitat, at appropriate seasons, anywhere in its past range, despite exhaustive surveys over a time frame appropriate to its life cycle and form.
Critically Endangered (CE)
The species is facing an extremely high risk of extinction in the wild and in the immediate future.
Endangered (EN) The species is likely to become extinct unless the circumstances and factors threatening its abundance, survival, or evolutionary development cease to operate; or its numbers have been reduced to such a critical level, or its habitats have been so drastically reduced, that it is in immediate danger of extinction.
Vulnerable (VU) Within the next 25 years, the species is likely to become endangered unless the circumstances and factors threatening its abundance, survival or evolutionary development cease to operate.
Conservation Dependent (CD)
The species is the focus of a specific conservation program, the cessation of which would result in the species becoming vulnerable, endangered or critically endangered within a period of 5 years.

Conservation categories for species described under the IUCN
Category Description
Extinct (EX) A taxon is Extinct when there is no reasonable doubt that the last individual has died. A taxon is presumed Extinct when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon's life cycle and life form.
Extinct in the Wild (EW)
A taxon is Extinct in the Wild when it is known only to survive in cultivation, in captivity or as a naturalized population (or populations) well outside the past range. A taxon is presumed Extinct in the Wild when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon's life cycle and life form.
Critically Endangered (CE)
A taxon is Critically Endangered when the best available evidence indicates that it meets any of the criteria A to E for Critically Endangered, and it is therefore considered to be facing an extremely high risk of extinction in the wild.
Endangered (EN) A taxon is Endangered when the best available evidence indicates that it meets any of the criteria A to E for Endangered, and it is therefore considered to be facing a very high risk of extinction in the wild.
Vulnerable (VU) A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable, and it is therefore considered to be facing a high risk of extinction in the wild.
Near Threatened (NT)
A taxon is Near Threatened when it has been evaluated against the criteria but does not qualify for Critically Endangered, Endangered or Vulnerable now, but is close to qualifying for or is likely to qualify for a threatened category in the near future.
Data Deficient (DD) A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status. A taxon in this category may be well studied, and its biology well known, but appropriate data on abundance and/or distribution are lacking. Data Deficient is therefore not a category of threat. Listing of taxa in this category indicates that more information is required and acknowledges the possibility that future research will show that threatened classification is appropriate. It is important to make positive use of whatever data are available. In many cases great care should be exercised in choosing between DD and a threatened status. If the range of a taxon is suspected to be relatively circumscribed, and a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified.

APPENDIX 2 Vegetation condition scale
(as developed by Keighery 1994)
Detailed Flora and Vegetation Survey Lot 500, Great Eastern Highway, Yilkari
50
Condition Code Description
Pristine 1 Pristine or nearly so, no obvious signs of disturbance.
Excellent 2 Vegetation structure intact, disturbance affecting individual species and weeds are non-aggressive species.
Very Good 3 Vegetation structure altered; obvious signs of disturbance.
Good 4 Vegetation structure significantly altered by very obvious signs of multiple disturbances. Retains basic vegetation structure or ability to regenerate it.
Degraded 5 Basic vegetation structure severely impacted by disturbance. Scope for regeneration but not to a state approaching Very Good condition without intensive management.
Completely Degraded
6 The structure of the vegetation is no longer intact and the area is completely or almost completely without native species.
