Executive Summary Mega Lake Maitland Pty Ltd (Mega) commissioned Outback Ecology to undertake a flora and vegetation assessment of two proposed infrastructure areas for the Lake Maitland Uranium Project (the Project) . The Project is located approximately 100 kilometres (km) to the south-east of Wiluna and 30 km to the north of the existing Bronzewing Gold Project in the Murchison region of Western Australia (Figure 1 ). Infrastructure area A is 1,767 hectares (ha) and Infrastructure area B is 2,336 ha. Collectively, the two infrastructure areas form the Project area for this assessment (Figure 2 ).

The overall objectives of the flora and vegetation survey were to: • incorporate results of previous flora surveys undertaken within and adjacent to the Project area; • identify flora species, including conservation significant and introduced species present in the Project area; • map vegetation communities occurring within the Project area; and • assess the potential impacts of the Project on flora and vegetation.

A total of 160 quadrats (30 x 30 metres, or equivalent) were established within the Project area during three survey periods (May 2007, November 2007, and December 2009). Vegetation was described using the system developed by McDonald, R.C. et al. (1990). Vegetation condition was assessed using the Keighery scale (Keighery, 1994). In addition, the potential infrastructure footprints were searched for conservation significant species, in habitats likely to contain the conservation significant species identified from the database search.

A total of 256 species from 39 families and 83 genera were recorded across the Project area. The flora was dominated by the families Chenopodiaceae (42 taxa) and Mimosaceae (38 taxa). Other dominant families included Myoporaceae (29 taxa), Poaceae (18 taxa), Malvaceae (14 taxa), Proteaceae (13 taxa) and Myrtaceae (10 taxa).

No Declared Rare Flora (DRF) species were identified as occurring in the Project area. One specimen collected during the November 2007 survey, which had insufficient characters to enable its positive identification, was initially identified as the DRF species Eremophila rostrata. A successive flora survey in May 2009 enabled this species to be identified as Eremophila latrobei subsp. latrobei, a non-conservation significant species, which flowers between winter and early summer.

One potential Priority 3 flora species, Maireana prosthecochaeta, was recorded at one location in a May 2009 survey. Further survey work undertaken in December 2009 identified this as the common species Gunniopsis quadrifida species. Two weed species: Portulaca oleracea and Tribulus terrestris, were also recorded in the May and December 2009 surveys. These species are not listed as declared plants under the Agriculture and Related Resources Protection Act, 1976 .

A total of 40 vegetation associations were described and mapped across the Project area. These were grouped into four major vegetation types consisting of: • Salt Lake (playa) vegetation; • Kopi Ridge vegetation; • Calcrete vegetation; and • Plains vegetation.

Three vegetation associations are described within the Salt Lake (playa) vegetation association; three within the Kopi Ridge vegetation; 11 within the Calcrete vegetation, and 23 within the Plains vegetation.

The Plains vegetation communities demonstrate a higher degree of variation with 23 different vegetation associations. However, it was also observed that the majority of the species recorded in the Plains were widespread throughout these communities. A large percentage of the Project area consists of a single vegetation association characterised by fire successional vegetation, which is a consequence of sections of the Plains vegetation having been subjected to fire within the last five years.

The Kopi Ridge Vegetation association was initially observed to be of limited extent within the Project area, however a subsequent flora and vegetation survey undertaken in December 2009 established limited occurrence of this association outside the Project area. The Kopi Ridge Vegetation association is therefore considered regionally significant due to its restricted distribution within the bioregion. No Priority Ecological Communities or Threatened Ecological Communities occur in the Project area.

Mega Lake Maitland Pty Ltd – Lake Maitland Infrastructure Areas Level 2 Flora and Vegetation Assessment

1. INTRODUCTION 1.1 Project Background and Location Mega Lake Maitland Pty Ltd (Mega) commissioned Outback Ecology to undertake a terrestrial flora survey of two proposed infrastructure areas for the Lake Maitland Project (the Project). The Project is located approximately 100 kilometres (km) to the south-east of Wiluna and 30 km to the north of the existing Bronzewing Gold Project in the Murchison region of Western Australia ( Figure 1).

The two proposed infrastructure areas are located on the east and west sides of Lake Maitland. Within this report, these areas are referred to as Infrastructure area A and Infrastructure area B. Collectively, the two infrastructure areas form the Project area that was used during this flora and vegetation assessment (Figure 2 ). Infrastructure area A is 1,767 hectares (ha) and Infrastructure area B is 2,336 ha.

1.2 Report Scope and Objectives The botanical survey of the Project area was planned and implemented as far as practicable according to the Environmental Protection Authority (EPA) Position Statement No. 3 “Terrestrial Biological Surveys as an Element of Biodiversity Protection” (EPA 2002) and Guidance Statement No. 51 “Terrestrial Flora and Vegetation Surveys for Environmental Impact Assessment in Western Australia” (EPA 2004). The overall objectives of the flora and vegetation survey were to: • incorporate results of previous flora surveys undertaken within and adjacent to the Project area; • identify flora species, including conservation significant and introduced species present in the Project area; • map vegetation communities occurring within the Project area; and • assess the potential impacts of the Project on flora and vegetation.

The flora and vegetation assessment involved: • A desktop review of: - flora species and vegetation communities of conservation significance, potentially present in the Project area (including threatened and priority flora, geographically rare flora, rare species, and ecological communities); and - previous flora and vegetation studies conducted in the Project area and surrounding areas. • Field surveys incorporating the identification of: - flora species found in the Project area; - conservation significant flora species; and - vegetation communities and condition. • An assessment of the conservation value of flora and vegetation in a local, regional and national context.

1.3 Legislative Requirements 1.3.1 Environment Protection and Biodiversity Conservation Act 1999 The EPBC Act is a Commonwealth Act with a focus on matters of National Environmental Significance (DEWHA, 2008). The EPBC Act serves to provide a means to manage threats to the natural environment by: • providing for the protection of biodiversity conservation through the identification of threatening processes, protecting critical habitat, preparation of management plans and issuing conservation orders • providing for compliance and enforcement through a range of actions, including court injunctions and environmental auditing • providing for an additional level of approval for activities likely to impact on aspects of the natural environment protected under the EPBC Act .

Approval from the Minister for the Environment, Water, Heritage and the Arts must be sought to undertake any action that is likely to have a significant impact on Threatened Ecological Communities (TECs) and protected flora species listed under the EPBC Act. There are three categories of TECs under the EPBC Act, namely, ‘Critically Endangered’, ‘Endangered’ and ‘Vulnerable’ which are defined within Appendix A to this report..

1.3.2 Western Australian Wildlife Conservation Act 1950 Rare flora is gazetted under subsection 2 of section 23F of the Western Australian Wildlife Conservation Act 1950 (WC Act, 1950) . Species which may be rare, but about which insufficient data has been collected to determine abundance, may be placed on the priority flora list. The priority flora list does not have the same legal status as the DRF schedule. However, priority flora are considered under the Environmental Protection Act 1986, as enforced by the Environmental Protection (Clearing of Native Vegetation) Regulations 2004 , when determining the biodiversity value of an area (DoIR, 2006). Definitions of declared rare and priority flora species (i.e., Priority 1 to Priority 4) are provided in Appendix A.

In WA, the DEC recognizes four categories of TECs, as developed by English and Blyth (1997). These are ‘Presumed Totally Destroyed’, ‘Critically Endangered’, ‘Endangered’ and ‘Vulnerable’ and definitions are supplied for each within Appendix B.

Other ecological communities that are considered to possibly be under threat, but do not meet the survey criteria associated with TEC, are listed under the DEC’s Priority Ecological Community (PEC) List as Priorities 1, 2 and 3. Those ecological communities which are considered to be adequately known and are rare but not threatened, or that have been recently removed from the threatened list, are classified as Priority 4 and require regular monitoring. Conservation dependent ecological communities are classified as Priority 5 (Naturebase, 2007).

In addition to TECs and PECs, ecosystems have been described as being ‘at risk’ (Cowan 2001). Whilst not conferring any form of legislative protection, the application of the ‘at risk’ status is a useful tool that highlights ecosystems that may be subject to threatening processes.

2. EXISTING ENVIRONMENT 2.1 Biogeographic Region Thackway and Cresswell (1995) describe a refined system of 85 ‘biogeographic regions’ (bioregions) covering the whole of Australia; the result of collaboration between all state conservation agencies with co- ordination by the Australian Government Department of Environment and Heritage [now the Department of Environment, Water, Heritage and the Arts (DEWHA)]. Bioregions are defined on the basis of climate, geology, landforms, vegetation and fauna.

The Project area is located within the Murchison bioregion (Australian Natural Resource Atlas [ANRA], 2 2007) in Western Australia. The Murchison covers an area of 278,360 km with mining and grazing as the two main land uses (Morton et al. 2004). The Murchison bioregion is further delineated into two sub- regions; the Eastern Murchison and the Western Murchison. The Project area is located within the Eastern Murchison (MUR1) sub-region ( Figure 3 ) characterised by Cowan (2001) as:

“internal drainage and extensive areas of elevated red desert sandplains with minimal dune development. Salt lake systems are associated with the occluded Paleodrainage system. Broad plains of red-brown soils and breakaway complexes as well as red sandplains are widespread. Vegetation is dominated by Mulga Woodlands often rich in ephemerals, hummock grasslands, saltbush shrublands and Halosarcia (now Tecticornia) shrublands”.

2.2 Land Systems of the Project area The Western Australian Department of Agriculture completed a regional survey of land systems occurring within the Murchison to develop a comprehensive description of biophysical resources and to provide an assessment of the condition of the soils and the vegetation of the north-eastern Goldfields (Pringle et al. , 1994). A component of the survey was the mapping of land types, land units and land systems of the Murchison including the Project area.

The East Infrastructure area is located predominantly over the Bullimore land system (Figure 4 , Table 1 ). However, the Mileura, and to a lesser degree, the Darlot and Melaleuca land systems also occur. The West Infrastructure area is located predominantly over the Mileura and Cunyu land systems. However, a small portion of the West Infrastructure area also occurs over the Darlot land system. The Bullimore land system is represented by extensive Spinifex sandplains, whereas the Mileura and Cunya land systems are represented by calcrete platforms and support halophytic and Acacia shrublands respectively.

2.3 Land Use 2.3.1 Pastoral The Project is situated on the Barwidgee Pastoral Lease, which is currently leased by Mega. Barwidgee has been stocked since the 1930s (Beard, 1975), and the grazing of both cattle and Damara sheep currently occurs within selected areas of the lease, including the Project area. In addition to grazing, there are high numbers of both Red Kangaroos (Macropus rufus ) and Euros (M. robustus ) (National Land and Water Audit [NLWRA], 2002).

2.3.2 Mining The Lake Maitland uranium deposit was discovered by Asarco Australia Pty Ltd in 1972. The deposit was drilled by Mt Isa Mines Ltd (now Xstrata Ltd) and Esso Exploration Ltd in the 1980s and 1990s and by Mega Lake Maitland in late 2005. The uranium resource has been inferred as a 100 ppm U 3O8 cut-off, of 32.7 million tones at 0.03 % U 3O8 (23.7 million pounds U 3O8) (JORC and NI-43-101 compliant) (Mega Uranium, 2007). The Lake Maitland Study area is located within 25 km of View Resource’s Bronzewing Gold Mine, which is also located on the Barwidgee Pastoral Lease.

2.4 Landforms and Landscape Positions Landforms typically have unique environmental parameters such as slope, surface hydrology, erosion and consequently vegetation. Vegetation types are not always wholly confined to a landform with several types often occurring in the one landform. For the purpose of describing the vegetation, landscape position was used in conjunction with the landform. As part of the broader environmental assessment Outback Ecology identified four distinct soil-landforms across the Project area namely inland Kopi Ridges/Dunes, Salt Lake, Calcrete and Sand Plains. All of which were used to describe the vegetation types mapped across the Project area.

2.5 Climate The Murchison region is characterised as having an arid climate, with summer and winter rain and an annual rainfall in the range of 200 mm (Beard, 1990; Gilligan, 1994). The area has a bimodal rainfall distribution, with both summer and winter rain (Beard, 1990; Gilligan, 1994). However, rainfall over the Project area is unreliable, with zero rainfall potentially recordable in any month (Gilligan, 1994).

Summer weather in the region is influenced by anticyclonic systems to the south-east, which result in a pattern of clear skies and easterly winds (Gilligan, 1994). The region borders the southern end of the Intertropic Convergence Zone and, as a consequence, thunderstorm activity and summer rainfall is generated (Gilligan, 1994). While summer rainfall is a feature of the region, most years have a dry spell lasting four to six months, typically commencing around October (Gilligan, 1994).

11 Mega Lake Maitland Pty Ltd – Lake Maitland Infrastructure Areas Level 2 Flora and Vegetation Assessment

Winter weather patterns are directly influenced by the anticyclonic system, which results in the generation of westerly winds and rain-bearing frontal systems (Gilligan, 1994). Winter rains are usually heaviest around late May into August, and subside during the months of September and October as the anticyclonic conditions stabilise (Gilligan, 1994).

The nearest Bureau of Meteorology (BOM) weather stations to Lake Maitland are Yeelirrie and Leinster. Data has been collected at Leinster since 1985, whereas rainfall data has been collected at Yeelirrie since 1928, with temperature data collected since 1973. To give a better representation of long-term regional climate patterns, data from Yeelirrie weather station were selected. The Yeelirrie weather station is located approximately 98 km west of Lake Maitland. Significant variation in rainfall is noted across the area, and as such, data provided should be used as a guide only.

Monthly mean maximum temperature at Yeelirrie ranges from a high of 37.9 ºC during January to a low of 19.3 ºC in July ( Figure 5). The highest temperature at Yeelirrie was 46 ºC recorded in February 1991 while the lowest was -5.1 ºC recorded in July 2000 (BOM, 2009). Mean monthly rainfall at Yeelirrie ranges from a high of 31.5 mm in March to a low of 4.2 mm in September ( Figure 5). Mean annual rainfall recorded at Yeelirrie is 237 mm (BOM, 2009). Zero rainfall has been recorded during each month of the year while peak falls as high as 211 mm (April, 1992) have been recorded within a month (BOM, 2009). Annual rainfall recorded has ranged from a low of 42.8 mm in 1950 to a peak of 506.8 mm in 1975 (BOM, 2009).

3. MATERIALS AND METHODS A Level 2 survey was undertaken within the Project area in accordance with the EPA Guidance Statement No 51 (EPA 2004). This level of survey requires a desktop review, incorporating a literature review, database searches and reviews of maps of the proposed area of disturbance. The Level 2 survey further describes the flora and vegetation through a series of quadrats (30 x 30 m) placed within vegetation units determined prior to field survey and includes at least one visit to the project area within the main flowering season, plus at least one visit in other seasons.

3.1 Desktop Review A review of databases and publicly available information was conducted prior to the field survey, to determine flora species and vegetation types of conservation significance known or likely, to occur within the Project area and surrounds. The DEC definitions for DRF, Threatened Flora and Priority Flora are provided in Appendix A.

3.1.1 Database Searches A review of databases and publicly available information was conducted prior to the field survey for flora species and vegetation communities of conservation significance known to, or likely to occur within the Project area. A search of the databases was undertaken for an area of approximately 100 km 2 surrounding the Project area, using the following boundary co-ordinates: • NW corner – S26° 15’, E120° 00’ • SE corner – S28° 03’, E122° 04’.

Databases and public information sources searched included the: • Protected Matters database for flora of conservation significance and TECs listed under the Commonwealth Environment Protection and Biodiversity Conservation (EPBC) Act, 1999 (Department of Environment, Water, Heritage and Arts (DEWHA), 2009); • Threatened (Declared Rare) Flora database, TEC database and the DRF and Priority Flora List sourced from the WA DEC (DEC, 2009); • Western Australian Herbarium (WAH) database for rare and priority flora (WAH, 2009).

3.1.2 Literature Review Previous flora surveys completed in the immediate vicinity of the Project area are: • Cowan (2001), DEC Biodiversity audit report for the Murchison 1 Bioregion ; • Pringle, H.J.R, Van Vreeswyk, A.M.E. and Gilligan, S.A. (1994), An inventory and condition survey of the north-eastern Goldfields, Western Australia. • Outback Ecology (2009), Lake Maitland: Baseline Vegetation and Flora Surveys – May and November 2007 and May 2009.

3.2 Field Survey 3.2.1 Survey Timing and Weather The survey was conducted from 11 th January to 5th February 2010 in conjunction with a survey of areas associated with proposed geotechnical test drilling sites. Rainfall in the months preceding the survey was below average, with only 7.1 mm of rain falling from July to December 2009 ( Figure 5). In January 2010, 17.2 mm was recorded.

3.2.2 Survey Design and Rationale Prior to the field survey, relevant supporting information was reviewed, which included database searches ( Section 3.1.1 ), previous vegetation surveys/mapping in the general area ( Section 3.1.2 ), topography, and land system mapping (Van Vreeswyk et al. 2004).

The distribution of vegetation communities and subsequent siting of survey quadrats was planned using aerial photography, with alterations made following an on-ground review of the Project area. Data was collected from 30 x 30 m quadrats, relevés and opportunistic collections. Where a 30 x 30 m quadrat was not suitable for the location, appropriate dimensions where used ensuring the same total area searched.

A total of 160, 30 x 30 m (or equivalent) quadrats were established within the Project area during three survey periods (May 2007, November 2007, and December 2009). Where possible, a minimum of two quadrats were established within each vegetation association. Quadrats were generally positioned within the Project area. However, as the Project area was an irregular shape, some quadrats were placed adjacent to the boundaries within more representative vegetation. Each quadrat was oriented in a north-south east-west direction with a GPS reading taken at each corner of the quadrat.

For each quadrat, the following information was recorded: • GPS Location (recorded in GDA94 UTM 50K) ( Appendix C); • a photograph taken of the vegetation from the NW corner; • habitat type; • vegetation condition, based on Keighery (1994)( (Appendix D); • vegetation description, based on the vegetation structural table of McDonald et al 1990). (Appendix E ); • species present with estimated height and percentage foliage c over; • topographic position; • slope and aspect; • soil type; • presence of outcropping and exposed rock type ; • bare ground and litter percentages; • estimated time since fire; and • disturbance level and description.

In addition to the quadrats, 22 relevé’s were also sampled throughout the Project area. A relevé is a description of a homogenous stand of vegetation without the boundaries imposed by a quadrat, the results of which are not used in statistical analysis. Relevés allow for the dominant species and unique features of a site to be captured quickly, allowing for a more accurate representation of the vegetation to be mapped and anomalies across the site to be captured. It was not possible to situate quadrats in some narrow linear vegetation types such as drainage lines, thus relevés were used in such situations.

Datasheets with the quadrat information are included in Appendix F.

Other flora species of interest were opportunistically observed/collected within the Project area and recorded. All quadrat and relevé data, along with these opportunistic recordings, were entered into an MS Access database (‘Site Species’, developed by Ted Griffin and Malcolm Trudgen) for generation of species lists and further data analysis.

3.2.3 Identification of Flora Specimens Common species well known to the survey botanists were identified in the field. Voucher specimens of all other species were collected and assigned a unique number to facilitate tracking of data. These vouchers were then identified by keying out, reference to appropriate publications, use of voucher reference collections and comparison to the collections held at the Western Australian Herbarium. Most specimens were identified by Dr. Aleida Williams (Outback Ecology).

Nomenclature was checked against the current listing of scientific names recognised by the Western Australian Herbarium and species and genus nomenclature updated as necessary. Family listing is co-aligned with the pre-February 2010 Systematic sequence. In February 2010 the Western Australian Herbarium updated its systems.

Specimens will be lodged with the Western Australian Herbarium for all species representing flora of conservation significance, undescribed species, range extensions or gaps in the known species, provided that adequate material is available.

3.2.4 Survey for Flora of Conservation Significance Botanists from Outback Ecology walked systematic traverses through the entire Project area to search for rare flora in May and December 2009. In both instances, the survey timing followed below-average summer rainfall. Therefore, annual flora is unlikely to have been abundant within the Project area. However, as a number of relatively inconspicuous ephemeral species (including annual daisies) were recorded, it appears that the survey work was adequately thorough.

Where suspected Priority Flora were located, GPS position and photographs were taken and population counts conducted. Voucher specimens were also collected for lodgement with the Western Australian Herbarium.

16 Mega Lake Maitland Pty Ltd – Lake Maitland Infrastructure Areas Level 2 Flora and Vegetation Assessment

Introduced flora were also recorded as part of this exercise. Any additional native flora species that had not been previously recorded in the area by the survey team were also noted during these traverses.

All records of rare flora and the less common weed species are displayed on the vegetation mapping in Figure 6.

3.2.5 Vegetation Mapping and Condition Prior to the survey, vegetation units were identified as far as practicable on aerial photographs of the Project area in conjunction with relevant supporting documentation (listed in Section 3.1). Quadrat data and field observations were used to refine vegetation association mapping boundaries. Vegetation communities were described using vegetation classification based on height and estimated cover (Appendix E).

The vegetation descriptions were then grouped to arrive at vegetation units that were defined on the basis of a shared suite of perennial species with a similar range of cover values. These were generally defined at the level of vegetation association, as per Level VI of the National Vegetation Information System (NVIS) classification framework, and have been listed under the main landform/habitat types in which they were found to occur.

3.2.6 Statistical Analysis Data for all quadrats from the Project Area was entered into PRIMER6 with all taxa included in the analysis. Analysis was carried out on a presence/absence basis, producing a dendrogram of site relationships that were used to validate broad floristic formations and vegetation communities observed during the field survey.

3.2.8 Constraints and Limitations The EPA (2004) lists a number of possible limitations and constraints that can impinge on the adequacy of flora surveys. These are listed in (Table 2), with an assessment relating to the 2009 surveys. All factors identified by the EPA (2004) were considered in the design of this survey, and none were determined to be a significant constraint.

Table 2 Summary of potential flora survey constraints

Aspect Constraint Comment regarding the flora and vegetation survey

Competency/experience No Members of the survey team were flora specialists employed by of consultants Outback Ecology, or sub-consultants, and have many years experience undertaking flora surveys of this kind within the Murchison region of WA.

Scope No The scope was clearly defined and realistically achievable.

Proportion of flora Yes Of the 256 species detected during this survey 55 specimens could not identified be identified to species level. Flora surveys undertaken over the summer season does not allow accurate identification of non-flowering or fruiting species. This survey limitation is mitigated by the incorporation of previous surveys undertaken on and adjacent to the Project area in other seasons.

Information sources No A number of local and regional studies have been carried out. Available (e.g. historic or recent) data was reviewed prior to commencement of the survey.

Proportion of task No Proposed sites were reassessed on the ground, and all vegetation achieved, and further communities were examined. work which might be needed

Timing / weather / Yes The Outback Ecology survey was undertaken following poor rainfall season / cycle over the spring season. This issue is mitigated by the inclusion of survey data within the Project area from OES (2007 and 2009) where surveys were undertaken in various seasons and following differing rainfall events.

Disturbances Yes Disturbance as a result of livestock grazing activities and weed invasion was in most areas considered high.

Intensity No Survey intensity was adequate.

Completeness No The majority of the area was traversed on foot with at least two quadrats placed within each vegetation association. The survey is considered complete.

Resources No WAH specimens, taxonomic guides, DEC Database Searches and Florabase, were all used to prepare for the trip and used for the confirmation of any species where their identification was uncertain. Resources were adequate to carry out the survey satisfactori ly.

Remoteness / access No All survey quadrats were accessible by 4WD vehicle and/or on foot. problems While terrain was difficult to traverse all areas were covered and access was not considered a limitation.

Availability of contextual No Information was available for the Interim Biogeographic Regionalisation information for Australia (IBRA), FloraBase, DEC lists and BoM.

4. RESULTS AND DISCUSSION 4.1 Desktop Review Background 4.1.1 EPBC Protected Matters Database Search The search of the EPBC Act 1999 Protected Matters Database for the defined search area around the Project area ( Appendix G) revealed: • No known TECs • No flora of conservation significance

In addition to flora and vegetation of conservation significance, the database was also searched for areas of national and international importance. The results of this search are: • No World Heritage areas • No National Heritage areas • No RAMSAR wetlands

Three places were identified as being on the Register of the National Estate, one of which is Wanjarri, an A Class Reserve vested in the DEC and listed as a State Reserve.

The Wanjarri Reserve is recognised as significant due to the diverse flora and fauna it contains. Predominantly its values relate to the diversity of bird species (111 species) that occur there, largely because of its location, where ranges of these species with predominantly southern, eastern or northern distributions overlap. It includes areas of ungrazed mulga. This reserve is 53,250ha in areas and occurs adjacent Wiluna - Leinster Road, 47km north of Leinster and 90 km south-east of Wiluna approximately 40km from the Project area.

4.1.2 Declared Rare Flora Occurring in the Locality The search of the DEC databases and Priority Flora list and the Western Australian Herbarium database for the defined search area around Project area ( Table 3) revealed: • No Declared Rare Flora (DRF) • 27 Priority taxa (Western Australian Herbarium) consisting of: o Twelve P1 taxa; o Two P2 taxa; o Six P3 taxa; and o Five P4 taxa. • One TEC – Depot Springs Stygofauna Community. • No PECs

The nearby Depot Springs Stygofauna TEC is not ecologically significant based on the community’s flora and vegetation. Therefore, it is not considered significant in the context of this flora and vegetation assessment. This TEC occurs outside the Project area and is not a defined vegetation association within the Project area.

‘At risk’ ecosystems were cross referenced with current DEC listed TEC/PEC’s. No current TEC/PEC’s occur within the Project area or are likely to be impacted by proposed development. Calcrete vegetation similar to that found in Area A is not listed as a TEC/PEC but has been identified as an ‘at risk’ ecosystem by Cowan (2001). Calcrete vegetation is currently on a DEC ‘internal working list’ which means that more information on the location, distribution and threats of the vegetion is needed before the DEC can determine if these communities should be placed on the DEC Priority Ecological Communities list. Processes threatening the identified Calcrete ‘at risk’ ecosystems (Cowan 2001) relate to grazing, feral animals and changed fire regimes rather than small scale clearing. These threatening processes are not considered to be influenced by disturbances arising from mining and related activities.

4.1.3 Literature Review Pringle, H.J.R.; Van Vreeswyk, A.M.E. and Gilligan, S.A. (1994) An inventory and condition survey of the north-eastern Goldfields, Western Australia. Dept. of Agric. West. Aust. Technical Bulletin 87 A regional survey of land in the north-eastern Goldfields was undertaken between 1988 – 1990 by the Department of Agriculture (now Department of Agriculture and Food) and the Department of Land Administration (now Landgate). The purpose of the survey was to develop a comprehensive description of the biophysical resources and an assessment of the condition of the soils and the vegetation of the north-eastern Goldfields (Pringle et al. 1994).

The survey found that Acacia aneura (Mulga) was the dominant species within the survey area, occurring along greenstone ranges and gently undulating sandplains. Halophytic vegetation was also common throughout the survey area, occurring within salt lake systems and breakaways (Pringle et al. 1994).

The survey identified 825 taxa representing 82 families and 290 genera, with the dominant families being Myrtaceae (88 taxa), Chenopodiaceae (71 taxa), Myoporaceae (56 taxa) and Mimosaceae (55 taxa). Furthermore, the survey identified 4 Declared Rare Flora (DFR) and 24 Priority Flora. However, since the time of the survey a number of taxa have had their conservation significance level downgraded or have been removed from the Priority Flora list. Currently there is one DRF and 21 Priority Flora species recognised from this work (Table 4).

Cowan does not identify any TEC’s within the MUR1, and a number of ecosystems ‘At Risk’ (Appendix H ). Processes threatening ‘At Risk’ ecosystems identified by Cowan (2001) relate to grazing, feral animals and changed fire regimes.

Outback Ecology 2009 Baseline Vegetation and Flora Surveys – May and November 2007 Mega commissioned Outback Ecology Services (Outback Ecology) to undertake baseline flora and vegetation surveys over the Lake Maitland project area. Outback Ecology conducted surveys during May and November 2007. The flora and vegetation surveys were one component of a broader assessment undertaken concurrently by Outback Ecology. These included surveys for vertebrate fauna, aquatic ecology, stygofauna and soils.

During the May survey, a total of 52 quadrats were assessed across the project area. An additional 30 quadrats were assessed in the project area during the November survey. Vegetation was described using the Muir scale (Muir, 1977). Vegetation condition was assessed using the Keighery scale (Keighery, 1994).

A total of 161 taxa (including subspecies and variants) from 29 families and 60 genera were recorded across the Lake Maitland project area. The flora was dominated by the family Chenopodiaceae, with 35 taxa recorded. Other dominant families included Mimosaceae (23 taxa), Myoporaceae (15 taxa) and Poaceae (14 taxa). One Declared Rare species, Eremophila rostrata, was recorded at one location. No Priority Flora were recorded during the surveys. No alien taxa were recorded during the surveys.

A total of 40 vegetation units were described and delineated across the Project area. These were grouped into four vegetation associations; Salt Lake (playa), Kopi Ridge, Calcrete Platform and Plains. Sections of the Plains vegetation unit had been subjected to fire within the last 1-5 years, resulting in successional vegetation that is different from the surrounding vegetation.

The condition of vegetation across the Project area ranged from ‘pristine’ to ‘degraded’. Vegetation condition was adversely impacted by four main disturbances; grazing activities of cattle, kangaroos and rabbits; fire; vehicle movements; and mine exploration activities.

The vegetation of the Kopi Ridges was considered to be regionally significant, due to the discontinuous nature of the ridges and the comparatively low cover of this landform feature relative to the surrounding landforms. In addition to this, many of the species identified on the ridges were restricted to those ridges.

4.3 Conservation Significant Flora No DRF species were indentified as occurring within the Project area. Targeted surveys for potentially occuring species, based upon habitat assessment did not locate any DRF within either Infrastructure area.

No Priority flora specieswere recorded during the survey of the Project area. However, the survey did identified 4 new locations and 14 range extensions of existing taxa populations ( Table 7). Of particular interest was Rhagodia spinescens which was identified within the Project area at Lake Maitland and this record considerably extends its known range. This species was recorded occasionally within Acacia aneura Woodlands (4a and 4h associations), within Eucalyptus eremicola Woodland (1a and 1c associations) and Acacia ayersiana Woodland (6a association).

4.4 Introduced Flora A total of 27 weed species were identified in the the literature review process which included five species that are Declared plants under the Agriculture and Related Resources Protection Act, (1976 ) (ARRP Act); *Argemone ochroleuca (Mexican poppy) , *Carthamus lanatus (Saffron thistle) , *Datura stramonium (Thornapple), * Emex australis (Double gee) and *Xanthium spinosum (Bathurst burr).

The field survey only identified two introduced species (Portulaca oleracea and Tribulus terrestris ) in very low densities at only two sites within the Project area. Neither is classified as a Declared Plant and no Declared plants listed under the ARRP Act were observed.

4.4.1 Statistical Analysis The results of the statistical analysis were considered in relation to the field observations and the resultant vegetation associations and descriptions as mapped. The resultant dendogram ( Appendix J) illustrates some distinct groups correlating to vegetation associations observed in the field (see Table 8).

The statistical analysis identified various groupings consistant with the vegetation associations observed in the field, with similarities ranging fron 30% to 80% with groupings. The Bray-Curtis Similarity analysis identified the following clusters indicating distinct vegetation types based upon presence/absence alone: • 1b Open mallee woodland of Eucalyptus eremicola subsp. peeneri over sparse shrubland of Acacia sibina over hummock grassland of Triodia basedowii . • 10a Sparse shrubland of Scaevola collaris over chenopod shrubland of Tecticornia halocnemoides subsp. halocnemoides , Tecticornia indica subsp. aff. bidens and Tecticornia aff . undulata over open tussock grassland of Aristida contorta , Eragrostis lanipes . • 3b Open woodland of Casuarina pauper over open shrubland of Acacia nyssophylla , Hakea preissii and Lycium australe over sparse chenopod shrubland of Atriplex amnicola , Maireana oppositifolia and Sclerolaena deserticola over sparse tussock grassland. • 4a Low open woodland of Acacia aneura (occasionally with A. ayersiana, A. duriscula, Eucalyptus eremicola ssp. peeneri, or Grevillea spp.) over tall open shrubland mostly of Eremophila spp. or Melaleuca interioris (occasionally Hakea preissii ) over mixed shrubland with Cratystylis subspinescens over open hummock grassland of Triodia basedowii over open tussock grassland of Aristida contorta and Eragrostis eriopoda

Where more than one vegetation community clusters together, those communities generally share a similar species composition. The exclusion of structure and abundance in the analysis, results in these communities being erroneously grouped ( Attachment H). The results illustrate the principal that floristic presence/absence data alone should not be used as a method for delineating vegetation associations.

4.4.2 Vegetation Associations Vegetation was mapped across four broad landforms observed during the survey, based on substrate:

Salt Lake (playa) Vegetation Three vegetation units were mapped across the Salt Lake/Playa landform, located in a large area in the south-west of the Project area. The vegetation consisted mainly of Chenopodiaceae and salt tolerant species.

Kopi Ridge Vegetation The Kopi Ridge landform was the smallest and most restricted, comprising three vegetation associations, and located at the central-southern boundary of the Project area. The species composition of the understory was relatively similar across the vegetation units. However, the overstorey is dominated by either Eucalyptus striaticalyx or Grevillea sarissa subsp.

Plains Vegetation The Plains landform was the most widespread and diverse, with 23 vegetation associations mapped across it. One vegetation unit ( 1b) completely covered the eastern boundary of the Project area. Much of the central section of the Project area was a mosaic of Plains vegetation associations. The Plains had been subject to fire within the last one to five years, resulting in successional vegetation associations that differed from the surrounding vegetation.

Calcrete Vegetation The Calcrete landform had 11 vegetation associations mapped across it, and bordered the Salt Lake/Playa vegetation associations on the western boundary of the Project area. Four of the vegetation associations have the same dominant overstorey of Casuarina pauper, with varying understorey species composition.

A total of 40 vegetation associations were described and delineated across the Project area (Figure 6). All of the 160 quadrats were able to be delineated within the 40 vegetation associations (Appendix F ), with at least one quadrat per vegetation unit. A full description of all vegetation associations is provided in Table 8.

4.5 Vegetation Condition Vegetation condition of the Project area was assessed using the Keighery scale (1994) ( Appendix D). Vegetation condition across the site ranged from ‘pristine’ to ‘degraded’. The vegetation was impacted by four main disturbances; activities of cattle, kangaroos and rabbits, fire, vehicles movements and exploration activities.

Grazing of vegetation was most evident on the calcrete areas located to the east and north of the site where palatable grass species were present. Cattle tracks within these areas ranged from minor to deep furrows. Evidence of rabbits (e.g. scats and burrows) was noted across the site, particularly within the Acacia and Triodia vegetation.

Adverse damage to vegetation had been caused by fires, particularly to the south and east of the Project area. The most recent fire occurred in April 2007, and areas recently burnt were excluded from the survey. Older fire scars displayed regeneration of vegetation, including Hakea lorea subsp. lorea and Eucalyptus eremicola subsp. peeneri , both resprouting after fire. However, repeated fires may impact on the recuperative capacity of the vegetation, ultimately leading to a loss of structure or diversity in affected areas.

Repeated fires can have adv erse consequences for fire sensitive plant species such as Mulga (Acacia aneura) (Fortech, 1999). Mulga is susceptible to fire and its range is restricted by the frequency and the intensity of fire which increases in spinifex dominated areas (Van Vreeswyk et al . 2004). A study of fire maps from the area indicated that fires had burnt across the area almost annually over the last five years, with some areas having been burnt several times.

Damage to vegetation has also occurred as a consequence of vehicle movement across the tenement. The scale of impact ranged from total removal of vegetation along firebreaks and access roads within the tenements to minor damage to vegetation from vehicle movement associated with exploration activities across the playa. Vegetation with low level infrequent vehicle disturbance was observed to be recovering, although some changes were evident with recruitment of native grass species occurring within the vehicle tracks.

There was low level damage to vegetation, primarily on the playa, as a consequence of exploration mining activities. The scale of impact was minimal and the vegetation was showing clear signs of recovering from the disturbance.

4.5.1 Vegetation Associations of Conservation Signficance No Threatened Ecological Communities (TECs) or Priority Ecological Communities (PECs), as defined by the DEC, were recorded in the Project Area. No ecosystems ‘At Risk’ (Cowan 2001) identified as TEC/PEC were located in the Project Area, however Calcrete vegetation is currently on a DEC

32 Mega Lake Maitland Pty Ltd – Lake Maitland Infrastructure Areas Flora and Vegetation Assessment

‘internal working list’, requiring further investigation for potential future listing. Processes threatening ‘At Risk’ Calcrete ecosystems as identified by Cowan (2001) relate to grazing, feral animals and changed fire regimes rather than small scale clearing. These threatening processes are not considered to be influenced by disturbances arising from mining and related activities.

33 Mega Lake Maitland Pty Ltd – Lake Maitland Infrastructure Areas Flora and Vegetation Assessment

IMPACT ASSESSMENT AND RECOMMENDATIONS 4.6 Project Area The vegetation of the Project area shows a clear delineation between the Playa vegetation and Plains vegetation. Vegetation on the playa and fringes is relatively uniform, with only minor variations observed, this is largely a consequence of changes in species density rather than diversity.

The Kopi Ridge community is considered to be of local conservation significance. There were some species within the Kopi Ridge community with highly restricted distributions for example, Eucalyptus striaticalyx and Grevillea sarissa subsp. bicolor were exclusively restricted to these ridges. The restricted distribution of these taxa makes them potentially more susceptible to the effects of disturbance associated with exploration and mining. It is recommended that disturbance of this restricted flora, as a result of proposed activities, be avoided or minimised.

The Plains vegetation is somewhat more complex. It is effectively a mosaic landscape, within which vegetation shows a high level of variation. While there were clear overarching vegetation groups, at the association level the vegetation is comprised of smaller discreet units, with a mix of species that are both common across the Project area and some that appear to have comparatively restricted distributions. Sections of the Plains vegetation have been subject to fire within the last one to five years, resulting in successional vegetation communities which differ from the surrounding vegetation.

The December survey was conducted in a floristically poor season following lower than average rainfall in the previous month. The incorporation of data from previous surveys in the locality, which were undertaken following differing climatic events and within different seasons, was undertaken to mitigate this potential survey limitation.

The proposed infrastructure areas which occur within the Project area, were targeted for DRF, priority species and conservation significant vegetation communities. No conservation significant flora or communities were identified within the Infrastructure areas.

4.7 Impact Assessment Construction of the proposed access tracks, the increased movement of people and vehicles across the landscape, the spread of introduced weed species, alterations to the site hydrology and dust all have the potential to affect vegetation within the Project area. An alteration to the current fire regimes is also a potential impact, but is not considered likely to occur.

The consequence of these impacts can be minimised through appropriate management and actions. These impacts are discussed below and general recommendations are provided in Section 5.3 to manage and mitigate their affect on the Project areas’ vegetation values.

4.7.1 Flora and Vegetation The extent to which vegetation associations are impacted by the proposal is dependent upon the final decision as to which proposed infrastructure area is selected. Table 9 provides the total area of each vegetation association within each proposed Infrastructure area. This table will updated during the Environmental Impact Assessment process when the infrastructure footprints have been finally identified.

While it is recommended tha disturbance to veetationin Area A be minimised, it is anticipated that less than 100ha will be cleared, and development is not considered to have a significant impact on the surrounding vegetation. Kopi Ridge vegetation associations in Area A should be avoided where possible.

Clearance associated with the Eastern Infrastructure area (Area B) would result in the clearance of less than 100 hectares of native vegetation. The associations within this area are relatively common within the Bioregion. Based upon areas of vegetation to be removed, and the proximity to existing access roads, it is recommended that Infrastructure area A be selected as it will result in lower levels of clearing of native vegetation. This option has potential to result in the clearing of Woodland of Acacia eyersiana which may contain the common taxa Rhagodia spinescens , which may however be locally signficant due to the extension of this species range.

No DRF listed under the WC Act 1950 or threatened flora listed under the EPBC Act was identified as occurring within the Project area. Based on targeted surveys within the Infrastructure areas, available habitat and known distribution, it is unlikely that any DRF or threatened flora occur within the Infrastructure areas. Therefore, it is unlikely that the Project would result in any impacts on DRF or threatened flora species.

Forty one vegetation associations within four broad landforms were mapped and described within the Project area. The vegetation is typical of that described in previous surveys within the area. None of the vegetation associations mapped and described are listed as TECs or PECs. Therefore the Project will not impact any currently listed TECs or PECs.

Vegetation condition across the majority of the Project area was rated as good to excellent condition except for those areas subject to grazing pressures by feral animals and cattle.

4.8 Management Recommendations 4.8.1 Introduced Weed Species No declared weed species were recorded during the survey of the Project area. However, there is the potential for weed species to be introduced to the Project area. A Weed Management Plan should be developed to prevent in ingress of weeds into the Project area.

4.8.2 Alterations to Site Hydrology Many of the vegetation associations present are ground water dependant. Several drainage lines and minor drainage lines were identified within the Project area and appear to be dependant on surface water drainage. The disturbance footprint has the potential to impact upon these drainage lines.

4.8.3 Dust Dust can be generated by various aspects of the site development process such as clearing, earthmoving and haulage (road and rail) as well as from infrastructure such as soil stockpiles. Dust may have physical effects on plants such as blockage and damage to stomata, shading, and abrasion of leaf surface or cuticle. Vegetation located close to dust sources is more likely to be subject to such impacts.

At the time of survey, no impacts from dust were evident. However, as vehicular movements are expected, together with earth moving operations associated with the construction of the required infrastructure, dust covering of vegetation along the haul roads or adjacent to plant infrastructure is likely to occur. Therefore, a dust management plan is recommended to ensure minimal impacts upon vegetation adjoining development areas.

4.8.4 Fire The age since fire occurred within the Project area was consistent for vegetation associations across the Project area, with the age identified as being between one and five years based on site knowledge and field observations. Triodia hummock grasslands are a prevalent ground cover throughout the Project area and are known to be highly flammable with the potential to spread wildfire rapidly.

The greatest period of fire risk from mining operations is during the clearing and exploration stages. During the clearing stage, grasses may become trapped under vehicles and ignite as a result of over heating. In comparison, the exploration stage can become a significant fire risk as a result of spark ignition from mechanical work being undertaken in hot dry weather. Therefore, a fire management plan is recommended to ensure no alterations to natural fire regimes within the Project area.

5. CONCLUSIONS AND RECOMMENDATIONS This assessment comprised a desktop and field survey to compile a species list, map the vegetation, and document any conservation significant flora and vegetation associations in the Project area.

5.1 Flora and Vegetation A total of 256 species from 39 families and 83 genera were recorded within the Project area.

No conservation significant flora species were recorded within the Project area during the survey. Historic disturbance to the Project area, together with the lack of suitable habitats for conservation significant species known to occur within the Murchison, suggest that these species are unlikely to occur within either proposed Infrastructure area. No TEC or PEC communities were identified as occurring within the Project area.

The proposed Infrastructure areas will not impact vegetation or flora that are unique to the area, nor will they fragment vegetation in such a way as to leave any that may be considered remnant.

5.2 Recommendations With respect to the two proposed infrastructure areas investigated, it is recommended that the western Infrastructure area is selected for the establishment of the mining facilities. This area has been historically disturbed by grazing activities and contains the least floristic constraints when compared to the eastern area.

Wherever practical it is advised to limit the amount of clearing to the areas proposed for development. Clearing should be limited to the footprint for the proposed development. No clearing should occur within identified Kopi Ridge areas (Figure 7 ) because while this habitat is found outside of the Project area, it is considered locally regionally restricted.

Rhagodia spinescens was identified in the Project area and represented a significant range extension for this species. This species was recorded occasionally within Acacia aneura woodlands (4a and 4h associations), within Eucalyptus eremicola woodland (1a and 1c associations) and Acacia ayersiana Woodland (6a association). This species is not known to occur within Infrastructure area A. A small area of potential habitat may be impacted should Infrastructure area B be selected however this is not expected to be significant as the species potential habitat in the Project area was extensive.

A dust management programme should be implemented during site construction activities to prevent dust from smothering flora and vegetation communities adjacent to site access roads and proposed infrastructure areas.

All roadways used for construction should be clearly signposted to eliminate vehicle movements into areas not associated with project access routes or the infrastructure footprint. This measure will prevent damage to flora and vegetation communities adjacent to construction and operational areas.

A sedimentation and erosion control plan should be implemented to eliminate adverse impacts upon vegetation communities downstream of the project. This plan should include appropriate measures for the management of roadways and any project infrastructure.

A Weed Management Plan should be developed for the site to prevent the ingress of weeds, or the movement of weeds throughout the site. Specific measures should be implemented to ensure vehicles entering the site are free from dirt or debris potentially carrying weed or the seeds of weed species.

A Bushfire Management Plan should be developed for the site to ensure that construction and operation of the proposed facility does not result in frequent fires. This management plan should also include measures to manage fire outside of the infrastructure areas.

Site induction training should also include information on the importance of maintaining vegetation, and the significance of some areas of the site for the conservation of significant species such as Rhagodia spinescens . This induction training should also highlight the importance of staying on designated access tracks with respect to minimising dust and the spreading of potential weed species.

Priority 1 Taxa which are known from few specimens or sight records from one or a few localities Taxa with few, poorly on lands not managed for conservation, e.g. agricultural or pastoral lands, urban areas, P1 known populations on active mineral leases. The taxon needs urgent survey and evaluation of conservation threatened lands. status before consideration can be given to declaration as threatened fauna.

Taxa which are known from few specimens or sight records from one or a few localities Priority 2 on lands not under immediate threat of habitat destruction or degradation, e.g. national Taxa with few, poorly P2 parks, conservation parks, nature reserves, State forest, vacant Crown land, water known populations on reserves, etc. The taxon needs urgent survey and evaluation of conservation status conservation lands. before consideration can be given to declaration as threatened fauna.

Priority 3 Taxa which are known from few specimens or sight records from several localities, Taxa with several, poorly some of which are on lands not under immediate threat of habitat destruction or P3 known populations, some degradation. The taxon needs urgent survey and evaluation of conservation status on conservation lands before consideration can be given to declaration as threatened fauna.

Taxa which are considered to have been adequately surveyed, or for which sufficient Priority 4 knowledge is available, and which are considered not currently threatened or in need of Taxa in need of P4 special protection, but could be if present circumstances change. These taxa are usually monitoring represented on conservation lands.

Priority 5 Taxa which are not considered threatened but are subject to a specific conservation Taxa in need of P5 program, the cessation of which would result in the species becoming threatened within monitoring five years.

Appendix D Vegetation Condition Classification

D1 Mega Lake Maitland Pty Ltd – Lake Maitland Infrastructure Areas Flora and Vegetation Assessment

Vegetation Condition Scale (Keighery, 1994). Code Description

Pristine Pristine or nearly so. No obvious signs of disturbance.

Vegetation structure intact, disturbance affecting individual Excellent species and weeds are non-aggressive species.

Vegetation structure altered, obvious signs of disturbance. For example, disturbance to vegetation structure caused by Very Good repeated fires, the presence of some more aggressive weeds, dieback, logging and grazing. Vegetation structure significantly altered by very obvious signs of multiple disturbance. Retains basic vegetation structure or ability to regenerate it. For example, disturbance to vegetation Good structure caused by very frequent fires, the presence of some very aggressive weeds at high density, partial clearing, dieback and grazing. Basic vegetation structure severely impacted by disturbance. Scope for regeneration but not to a state approaching good condition without intensive management. For example, Degraded disturbance to vegetation structure caused by very frequent fires, the presence of very aggressive weeds, partial clearing, dieback and grazing. The structure of the vegetation is no longer intact and the area is completely or almost completely without native species. These Completely Degraded areas are often described as ‘parkland cleared’ with the flora comprising weed or crop species with isolated native trees or shrubs.

Other Matters Protected by the EPBC Act This part of the report summarises other matters protected under the Act that may relate to the area you nominated. Approval may be required for a proposed activity that significantly affects the environment on Commonwealth land, when the action is outside the Commonwealth land, or the environment anywhere when the action is taken on Commonwealth land. Approval may also be required for the Commonwealth or Commonwealth agencies proposing to take an action that is likely to have a significant impact on the environment anywhere.

The EPBC Act protects the environment on Commonwealth land, the environment from the actions taken on Commonwealth land, and the environment from actions taken by Commonwealth agencies. As heritage values of a place are part of the 'environment', these aspects of the EPBC Act protect the Commonwealth Heritage values of a Commonwealth Heritage place and the heritage values of a place on the Register of the National Estate. Information on the new heritage laws can be found at http://www.environment.gov.au/heritage/index.html .

Please note that the current dataset on Commonwealth land is not complete. Further information on Commonwealth land would need to be obtained from relevant sources including Commonwealth agencies, local agencies, and land tenure maps.

A permit may be required for activities in or on a Commonwealth area that may affect a member of a listed threatened species or ecological community, a member of a listed migratory species, whales and other cetaceans, or a member of a listed marine species. Information on EPBC Act permit requirements and application forms can be found at http://www.environment.gov.au/epbc/permits/index.html .

Caveat The information presented in this report has been provided by a range of data sources as acknowledged at the end of the report. This report is designed to assist in identifying the locations of places which may be relevant in determining obligations under the Environment Protection and Biodiversity Conservation Act 1999 . It holds mapped locations of World Heritage and Register of National Estate properties, Wetlands of International Importance, Commonwealth and State/Territory reserves, listed threatened, migratory and marine species and listed threatened ecological communities. Mapping of Commonwealth land is not complete at this stage. Maps have been collated from a range of sources at various resolutions. Not all species listed under the EPBC Act have been mapped (see below) and therefore a report is a general guide only. Where available data supports mapping, the type of presence that can be determined from the data is indicated in general terms. People using this information in making a 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, remote sensing imagery and other sources. Where threatened ecological community distributions are less well known, existing vegetation maps and point location data are used to produce indicative distribution maps. For species where the distributions are well known, maps are digitised from sources such as recovery plans and detailed habitat studies. Where appropriate, core breeding, foraging and roosting areas are indicated under "type of presence". For species whose distributions are less well known, point locations are collated from government wildlife authorities, museums, and non-government organisations; bioclimatic distribution models are generated and these validated by experts. In some cases, the distribution maps are based solely on expert knowledge. Only selected species covered by the migratory and marine provisions of the Act have been mapped.

G3 Mega Lake Maitland Pty Ltd – Lake Maitland Infrastructure Areas Flora and Vegetation Assessment

The following species and ecological communities have not been mapped and do not appear in reports produced from this database: threatened species listed as extinct or considered as vagrants some species and ecological communities that have only recently been listed some terrestrial species that overfly the Commonwealth marine area migratory species that are very widespread, vagrant, or only occur in small numbers. The following groups have been mapped, but may not cover the complete distribution of the species: non-threatened seabirds which have only been mapped for recorded breeding sites; 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.
