EXECUTIVE SUMMARY Mount Gibson Mining Limited is seeking to obtain environmental approvals for the operational expansion of hematite production from its Mount Gibson Iron Ore Mine and Infrastructure Project, including a proposal to mine the Iron Hill deposits, approximately 2.5 km south of the existing Extension Hill mine.

To provide additional data on the flora and vegetation of the proposed Iron Hill disturbance area, including the delineation of floristic groups, Mount Gibson Mining engaged ecologia to complete a flora and vegetation assessment, including sampling 17 additional quadrats (each 20 x 20 m) within and adjacent to the proposed Iron Hill development envelope and floristic analysis to assess the vegetation at Iron Hill, incorporating the new floristic data and previously collected data. In addition, Priority flora searches were conducted across the study area in areas not known to be covered by previous targeted flora searches.

A total of 115 vascular flora taxa were recorded from the 17 quadrats and transects surveyed in April/May 2015. Eight of the quadrats are located within the area covered by the Iron Hill proposal and nine are located in similar vegetation nearby. The vegetation condition in all quadrats sampled in 2015 was rated as either ‘Excellent’ or ‘Very Good’. One Threatened flora species (Darwinia masonii) was recorded, within areas where the species has previously been recorded. No Priority flora taxa were recorded. Three range extensions were recorded: Hibbertia hypericoides, Hemigenia macphersonii and Sclerolaena eriacantha and eight additional taxa were recorded at the edge of their range: Eremophila eriocalyx, Eucalyptus kochii subsp. amaryssia, Leucopogon sp. Clyde Hill (M.A. Burgman 1207), Mirbelia sp. Bursarioides (T.R. Lally 760), Philotheca sericea, Prostanthera althoferi subsp. althoferi, Protanthera patens, Sida sp. Golden calyces glabrous (H.N. Foote 32). One introduced species (*Pentameris airoides subsp. airoides) was also recorded.

The 167 quadrats in the floristic analysis were classified into 14 floristic groups. Six of these floristic groups (A, B, C1, C2, E and K) are recorded at Iron Hill and Iron Hill South (collectively known as Iron Hill). Floristic groups are related to the geographic location of the quadrats, whereby the quadrats from Iron Hill ironstone ridges and slopes belong exclusively to groups E and K, and those from the shrublands and woodlands of the adjacent plains are represented in groups A, B , C1 and C2. Within the proposed Iron Hill development envelope, floristic groups E and K are associated with the ironstone hills and slopes and are considered to be key components of the Priority 1 Mount Gibson Range vegetation complexes (banded ironstone formation) Priority Ecological Community.

Floristic group K, the largest PEC floristic group (with respect to both number of quadrats and area mapped) was further divided into three subgroups, K1, K2 and K3. These three subgroups are similar in species composition and many taxa are common to all three subgroups, but may be represented in different frequencies.

1 INTRODUCTION

1.1 BACKGROUND

Mount Gibson Mining Limited is seeking to obtain environmental approvals for the operational expansion of hematite production from its Mount Gibson Iron Ore Mine and Infrastructure Project, including a proposal to mine the Iron Hill deposits, approximately 2.5 km south of the existing Extension Hill mine. The proposed Iron Hill Development Envelope is approximately 2.5 km wide and covers 112 hectares (ha). The Western Australian Environment Protection Authority (EPA) issued an Environmental Scoping Document (ESD) outlining additional environmental assessment works required prior to submission of the Public Environmental Review (PER) for the Iron Hill project.

In particular, this report and its content address the following ESD requirements:

10. In areas not already surveyed or where survey information is not of acceptable quality (such as incorrect survey season), standard and/or the proponent intends to use results from surveys at a lower level than a Level 2, justification will be required to ensure those surveys are relevant, representative of the development envelope, and were carried out using methods consistent with current best practice. A peer review of the vegetation and flora information by a botanist with appropriate experience and expertise would also be required.

11. Identify and map vegetation units (including sub-units of the plant assemblages of the Mt Gibson Range PEC) and DRF, Priority flora and other conservation significant flora species and their areas to be cleared or indirectly impacted as defined in EPA Guidance Statement 51. Provide details of the methodology used in the identification and mapping of vegetation units. The vegetation units should be based on floristics, rather than structural vegetation features. Describe the condition of the vegetation.

Conservation significant as defined in Guidance Statement 51 includes flora other than those that are listed at the State or national level as threatened, Priority and specially protected (e.g. endemic or restricted taxa, new taxa or affinities, taxa at the limits of their range, etc.).

12. Assess the impact on the different vegetation units (including sub-units of the plant assemblages of the Mt Gibson Range PEC).

To provide additional data on the flora and vegetation of the proposed Iron Hill development envelope, Mount Gibson Mining engaged ecologia to complete a flora and vegetation assessment, including sampling 17 additional quadrats within and adjacent to the proposed Iron Hill development envelope and floristic analysis to assess the vegetation values at Iron Hill, incorporating the new floristic data, and that previously collected by ATA Environmental in 2005 (ATA 2006b) and the Department of Environment and Conservation (DEC) Banded Iron Formation (BIF) survey conducted in 2005 (Meissner and Caruso 2008b). In addition, Threatened and Priority flora searches were conducted across the study area at approximately 50 m intervals, concentrating on areas not previously covered by targeted searches for Threatened and Priority flora. Threatened and Priority flora taxa with potential to occur within the Iron Hill development envelope include: • Darwinia masonii (Threatened) listed as Vulnerable under the WC Act and EPBC Act; • Lepidosperma gibsonii (Threatened) listed as Vulnerable under the WC Act); • Acacia cerastes (Priority 1); • Allocasuarina tessellata (Priority 1); • Chamelaucium sp. Yalgoo (Y. Chadwick 1816) (Priority 1); • Grevillea scabrida (Priority 1); • Micromyrtus trudgenii (Priority 3);

• Persoonia pentasticha (Priority 3); and • Podotheca uniseta (Priority 3).

Monitoring. The original floristic data from the ATA (2006b) and Meissner and Caruso (2008) surveys were sourced for inclusion in the floristic analysis of this study.

1.3 Mid-west Regional Floristic Analysis

In addition to the floristic analysis presented in following sections, a separate regional floristic analysis was completed by van Etten (2013), which places the previously collected Iron Hill quadrats in the context of other district and regional quadrats. The regional floristic analysis includes the (ATA 2006b) and Meissner and Caruso (2008b) datasets from the Mt Gibson Ranges used in this analysis, as well as the following regional data sources: • DEC Tallering BIF Survey – 103 quadrats (Markey and Dillon 2008); • DEC Koolanooka and Perenjori Hills BIF Survey – 50 quadrats (Meissner and Caruso 2008a); • DEC Gullewa BIF Survey – 50 quadrats (Markey and Dillon 2010); • DEC Yalgoo BIF Survey – 55 quadrats (Markey and Dillon 2011); • Sandplains – 53 quadrats (Knuckey 2011); and • EnviroWorks Mummaloo Flora and Vegetation Survey – 98 quadrats (EnviroWorks 2012).

For analysis, quadrats from ironstone ridges at Mount Gibson Ranges were assigned as three groups: ‘Mount Gibson’ (generally the eastern part of the range); ‘Extension Hill’ (generally the northern part of the range); and, ‘Iron Hill’ (in the central part of the range). The ordination output (Appendix A) shows that the Mount Gibson Ranges quadrats are similar to each other. As a collective set, the ‘Mt Gibson’ quadrats are generally similar in floristic composition to Tallering quadrats, whereas ‘Extension Hill’ quadrats and most of the ‘Iron Hill’ quadrats are more similar to the BIF quadrats of Koolanooka and Perenjori Hills, although there is some overlap. Not unexpectedly, ‘Iron Hill’ quadrats are similar to ‘Mt Gibson’ in some cases and ‘Extension Hill’ in others.

Based on the regional analysis, van Etten (2013) found that: • Analysis of the EnviroWorks Consulting (2012) quadrat data using alternative multivariate

techniques had given strong support for the vegetation classification; in particular, the main plant communities defined by EnviroWorks Consulting (2012) closely matched those found in the multivariate study. This means that the technique is a strong surrogate for identifying floristic similarity between quadrats mapped as communities;

• Using only perennial species data in the multivariate analysis did not dramatically alter the vegetation classification with the main community types being consistently delineated and identified;

• A high level of floristic similarity was found between 100 m2 and 400 m2 quadrats surveyed. This supported the use of data from smaller sized quadrats in local and regional analyses;

• Multivariate analyses of the regional quadrat dataset shows that the vegetation of the Mummaloo area is dissimilar to the vegetation reported in other survey areas of the region. It is important to note that there is no broad-scale vegetation survey available for the region, with most surveys being restricted to particular geologies/landforms or development sites (e.g. Mt Gibson Iron Ore mine); and

• The vegetation of Mummaloo area and the flats adjacent to ranges is distinct from vegetation on ironstone and greenstone ranges of the region, including the PECs at ironstone ranges at Mt Gibson, Koolanooka and Blue Hills.

Other evident findings were: • Floristic composition in quadrats on most of the Mount Gibson tenements (Mt Gibson Mining),

being the sandplains and flats adjacent and partly within the PEC (but not on ironstone ridges or slopes) were largely dissimilar from quadrats on ‘Mt Gibson Surrounds’ (Figure 1.1). The clear distinction shows that the floristics of communities mapped on the Mt Gibson surrounds do not show general characteristics of the upslope or ironstone ridge communities;

• Mt Gibson ironstone communities and ‘Tallering BIF’ quadrats were similar, and clearly far more similar overall than ‘Mt Gibson Surrounds’ flats/plains or other regional ironstone ridge quadrats (being Yalgoo, Gullewa and Koolanooka-Perenjori). While they were similar to each other, they clearly are different to the floristics in quadrats adjacent to them on the flats and sandplains;

• The Iron Hill quadrat data map well within the typical set of floristic similarities from quadrats over Mt Gibson Ranges indicating that it is not atypical or unusual in its floristic composition for ironstone ridges or within the Mt Gibson Ranges.)

2 METHODS FOR SURVEY AND ANALYSIS

2.1 FLORISTIC SURVEY

Seventeen quadrats (20 x 20 m) were surveyed by two ecologia botanists from 29 April to 2 May 2015 (Matthew Macdonald and John Grantham under DPaW Licence to Take Flora for Scientific or Other Prescribed Purposes SL010976 and SL01141, respectively). Approximately 70% of the field survey duration was utilised establishing the floristic quadrats and the remaining time focussed on conducting traverses in areas which have not previously been targeted for Threatened and Priority flora. The nearest long term weather station is at Paynes Find (BoM Station 007139) approximately 60 km north-east of Iron Hill (BoM 2016). The mean rainfall (rainfall records from 1919 to 2016) for March and April is 24.7 mm and 26.0 mm respectively, but prior to the 2015 field survey 54.8 mm of rain was recorded in March and 32.6 mm recorded in April. Mean monthly rainfall and rainfall recorded at Paynes Find for the 12 months prior to the field survey are shown in Figure 2.1. The favourable conditions at the time of survey are corroborated by the presence of fruit and/or flowers on 49% of the vascular flora recorded.

Figure 2.1 – Mean monthly, 2014 (–) and 2015 (–) rainfall (Paynes Find BoM 007139)

Previous surveys completed at Iron Hill and incorporated into this assessment (ATA 2006b and Meissner and Caruso 2008b) were conducted in spring 2005 and include a total of 150 quadrats. This survey of 17 quadrats was conducted after autumn rains and is therefore suitable as a supplementary survey. Eight of the 17 quadrats are located within the area covered by the Iron Hill proposal and nine are located in similar vegetation nearby. Due to the spread of the previously sampled quadrats across the Mt Gibson Range and nearby hills and plains, the 17 quadrats from this survey were concentrated in and around the Iron Hill development envelope. Quadrat locations were selected to represent the range of vegetation at the site without duplicating sampling in areas where quadrats have been previously surveyed. The locations of the quadrats are shown in Figure 2.1.

Data collected at each quadrat includes: • Percentage cover for each species present using the cover ranges cited by NVIS and as a

percentage cover estimate (rounded to nearest 5%) along with presence/absence of fruit/flowers; • Landform element (morphological type, position and element type) that the plot occupies; • Degree and nature of any site disturbance (based on Trudgen (1991) scale); • Presence of coarse fragments on the surface (type and abundance); • Presence of rock outcrops (type and abundance); • Soil type (colour, profile, field texture and surface type); • Vegetation structure (scoring three layers for dominance, growth form, height and estimated

cover consistent with the National Vegetation Information System (NVIS) Level V); and • Data on position, slope, and aspect. Data from 150 previously surveyed quadrats (all quadrats were 20 x 20 m) from the following assessments was included in the floristic analysis: • 100 quadrats from ATA (2006b); and • 50 quadrats from Meissner and Caruso (2008b) which were sampled in September and October

2005. Floristic analysis of the amalgamated dataset, incorporating the newly collected (2015) floristic data, along with data previously collected by ATA Environmental in 2005 (ATA 2006b) and from the DEC BIF survey (Meissner and Caruso 2008b) was undertaken by experienced ecologia ecologist Dr Matthew Macdonald, who has extensive experience in multivariate statistical and floristic analysis. Floristic analysis was undertaken on presence/absence data from each quadrat, with species of annuals and geophytes excluded. Some taxa were consolidated to produce a single consistent dataset from the three data sources, consistent with Meissner and Caruso (2008b). The site by species matrix used in the floristic analysis therefore consisted of 167 quadrats and 184 taxa. A species accumulation curve is shown in Figure 2.2. The incidence-based species richness (ICE) is estimated at 238 species, of which the 184 taxa included in the analysis represent 77% of the expected species richness. A consolidated list of vascular flora recorded from the three surveys and included in the analysis is provided in Appendix B. Quadrats were classified into floristic groups based on differences in species composition using the Bray-Curtis coefficient and flexible UPGMA (Unweighted Pair-Group Mean Average) using PATN multivariate statistical program. The locations of quadrats representing these floristic groups formed the basis for mapping of the vegetation groups across the Mount Gibson Ranges and surrounding slopes and plains. Other sources of data which were used to inform the mapping of floristic groups include: terrain (elevation contours); locations of Threatened and Priority flora taxa, particularly the Threatened (Vulnerable) species Darwinia masonii and Lepidosperma gibsonii and field observations made during this survey and by Eco Logical for delineation of floristic group E across the Mount Gibson Ranges.

2.2 TARGETED SURVEY

Areas within the Iron Hill development envelope which have not been searched during previous surveys were traversed at approximately 50 m intervals to record Threatened and Priority flora in these areas. Most of the steeper areas associated with Iron Hill itself have previously been searched for Threatened and Priority flora (particularly Eco Logical 2014, but also other references listed in section 1.2). These previous targeted surveys cover virtually all of the Mt Gibson Range PEC; therefore additional targeted surveys outside the Iron Hill development envelope were not undertaken.

3 RESULTS AND DISCUSSION

3.1 FLORA

A total of 115 vascular flora taxa were recorded from the 17 quadrats and transects surveyed in 2015 (see Appendix B). Quadrat species richness varied from nine taxa at quadrat numbers 2 and 17 from sandplain shrubland to 26 taxa from quadrat numbers 9 and 11 from hilltop/hillslope shrubland. Site descriptions are provided in Appendix C.

The most species rich families were Myrtaceae with 20 taxa, Fabaceae with 18 taxa, Lamiaceae with 8 taxa, Chenopodiaceae and Proteaceae with 7 taxa each and Poaceae with 6 taxa. The most species rich genera were Acacia, with 13 taxa; Eucalyptus with 7 taxa; Melaleuca with 6 taxa; and Eremophila and Grevillea with 5 taxa each.

One listed Threatened flora species, Darwinia masonii (Vulnerable under the WC Act and EPBC Act) was recorded from Quadrats 8, 9, 10 and 11 on Iron Hill, within areas where the species has previously been extensively recorded (Eco Logical 2014).

Three range extensions were recorded:

• Hibbertia hypericoides – recorded at Quadrat 8 (outside the Iron Hill development envelope), approximately 100 km north-east of the nearest vouchered record. This species has also been recorded from both the ATA (2006b) and Meissner and Caruso (2008b) Gibson Range surveys, but apparently no specimen has been lodged with the Western Australian Herbarium;

• Hemigenia macphersonii – recorded from Quadrats 7 and 9 outside the Iron Hill development envelope, and quadrats 14 and 16 inside the Iron Hill development envelope, approximately 100 km south of the nearest vouchered record. This species has also been recorded from both the ATA (2006b) and Meissner and Caruso (2008b) Gibson Range surveys, but apparently no specimen has been lodged with the Western Australian Herbarium; and

• Sclerolaena eriacantha – recorded from Quadrat 10, inside the Iron Hill development envelope, approximately 100 km south of the nearest vouchered record.

Eight additional taxa were recorded at the edge of their range:

• Eremophila eriocalyx – recorded from Quadrat 10, inside the Iron Hill development envelope. • Eucalyptus kochii subsp. amaryssia – recorded from Quadrats 2 and 3 inside the Iron Hill

development envelope, and quadrats 4 and 15 outside the Iron Hill development envelope. This taxon was also recorded in the Meissner and Caruso (2008b) survey.

• Leucopogon sp. Clyde Hill (M.A. Burgman 1207) – recorded at Quadrats 7 and 15 outside the Iron Hill development envelope, and Quadrats 13 and 14 inside the Iron Hill development envelope. This taxon has also been recorded from both the ATA (2006b) and Meissner and Caruso (2008b) surveys.

• Mirbelia sp. Bursarioides (T.R. Lally 760) – recorded from one opportunistic collection on the lower slopes of Iron Hill approximately mid-way between Quadrats 12 and 13 within the Iron Hill development envelope. This taxon was also recorded in the Meissner and Caruso (2008b) survey.

• Philotheca sericea recorded at Quadrats 5 and 7 outside the Iron Hill development envelope, and Quadrats 11 and 14 inside the Iron Hill development envelope. This species has also been recorded from both the ATA (2006b) and Meissner and Caruso (2008b) surveys.

• Prostanthera althoferi subsp. althoferi – recorded from Quadrats 15 and 17 outside the Iron Hill development envelope, and Quadrats 13 and 16 inside the Iron Hill development envelope. This taxon was also recorded in the Meissner and Caruso (2008b) survey.



March 2016

• Protanthera patens – recorded from Quadrat 7, outside the Iron Hill development envelope. This species has also been recorded from both the ATA (2006b) and Meissner and Caruso (2008b) surveys.

• Sida sp. Golden calyces glabrous (H.N. Foote 32) – recorded from Quadrat 5, outside the Iron Hill development envelope.

Figures showing the distribution of vouchered records for range extension and range edge records are provided in Appendix D (Western Australian Herbarium 1998-2016). Specimens representing range extension and range edge records will be lodged with the Western Australian Herbarium (see Appendix E for list of voucher specimens).

One introduced species (*Pentameris airoides subsp. airoides) was from Quadrat 11 (inside the Iron Hill development envelope).

3.2 VEGETATION

The 167 quadrats in the floristic analysis were classified into 14 identifiable floristic groups based on the dendrogram produced by the PATN analysis (Figure 3.1). Six of these floristic units (A, B, C1, C2, E and K) are represented within the Iron Hill proposal and are summarised in Table 3.1. In general, the groupings are related to the geographic location of the quadrats, whereby the quadrats from Iron Hill ironstone ridges and slopes belong exclusively to Groups E and K, those from the footslopes belong to Group C2 and shrublands and woodlands of the adjacent plains are represented in Groups A, B and C1. This pattern of floristic composition changing with landscape position is consistent with the previous floristic analyses of the Mount Gibson Ranges (Griffin 2005; Meissner and Caruso 2008b). A two-way table of floristic groups and taxa is provided in Appendix F.

The vegetation condition in all 17 quadrats sampled in 2015 was rated as either ‘Excellent’ (13 quadrats) or ‘Very Good’ (4 quadrats).

3.2.1 Floristic Groups

Quadrats included in the floristic analysis of the 167 quadrats are clustered in the 14 floristic groups as follows (Figure 3.2): • A: Eucalyptus kochii sparse woodland over Melaleuca hamata, Acacia anthochaera and Acacia

ramulosa shrubland over Dianella revoluta herbs and Amphipogon caricinus var. caricinus tussock grasses. This floristic group is represented by five quadrats from the 2015 survey, all of which are located on the sandplains to the west of Iron Hill, in particular two quadrats (quadrats 2 and 3) are within the northern section of the proposed Iron Hill disturbance area, and three quadrats (quadrats 1, 4 and 17) are outside and adjacent to the proposed haul road alignment.

• B: Eucalyptus horistes open woodland over Acacia ramulosa and Cryptandra apetala shrubland over Triodia scariosa open hummock grassland. This floristic group is represented by two quadrats from the 2015 survey, both of which are located on the sandplains to the west of Iron Hill, one within (quadrat 16) the proposed haul road alignment and one outside (quadrat 6).

• C1: Eucalyptus loxophleba subsp. supralaevis and/or Eucalyptus kochii subsp. amaryissa woodland over Acacia tetragonophylla, Acacia anthochaera, Acacia assimilis subsp. assimilis, Eremophila clarkei, and Ptilotus obovatus shrubland over Austrostipa elegantissima tussock grasses. This floristic group is represented by six quadrats, four from the ecologia 2015 survey, and two from the DEC (Meissner and Caruso 2008b) survey. One ecologia 2015 quadrat (quadrat 13) is located within the Iron Hill development envelope, whereas the three remaining ecologia 2015 quadrats (quadrats 5, 7 and 15) are located on the colluvial plains to the west of Iron Hill, with one

• C2: Eucalyptus loxophleba subsp. supralaevis, Eucalyptus kochii subsp. amaryissa and/or Eucalyptus horistes mallee woodland over Acacia acuminata, Eremophila clarkei, Allocasuarina acutivalvis subsp. prinsepiana, Philotheca brucei, Dodonaea inaequifolia and Melaleuca hamata shrubland over Austrostipa elegantissima tussock grasses. This floristic group is represented by five quadrats, one from the ecologia 2015 survey, and four from the DEC (Meissner and Caruso 2008b) survey. One ecologia 2015 quadrat (quadrat 14) and two DEC quadrats (quadrats MTBGB21 and MTGB31) are located within the proposed Iron Hill development envelope, and the DEC quadrat MTGB32 located on the footslopes to the west of Iron Hill, with one DEC quadrat to the east of Mount Gibson (MTGB27).

• D: Represented by a single ATA quadrat at Mt Singleton. • E: Calycopeplus paucifolius, Acacia tetragonophylla and Ptilotus obovatus open shrubland over

Cheilanthes adiantoides ferns and Austrostipa elegantissima tussock grasses. This floristic group is represented by 15 quadrats on ironstone ridges, four within the Iron Hill proposal (DEC quadrats MTGB18, MTGB19 and MTGB20 and ATA quadrat 44) and the remaining eleven quadrats outside the proposed development envelope at Iron Hill (2015 quadrat 8), Iron Hill North (MTGB17 and ATA 42), and Mount Gibson (MTGB24, MTGB25). One DEC quadrat from near the Great Northern Highway (GNH3) and one from Yandhanoo Hills (YAND3), and two more distant ATA quadrats (ATA 63 and 64) also cluster with this group. This floristic unit includes Community Type 5 (six quadrats) and Community Type 1 (two quadrats) of the (Meissner and Caruso 2008b) assessment, and ATA (2006b) mapped vegetation units T3 (one quadrat), T5 (one quadrat) and HS1 (two quadrats).

• F, G, H, I, and J: All quadrats representing these groups are located away from the Mount Gibson Ranges, such as Yandhanoo Hills, Mount Singleton, Warroo Well and along the Great Northern Highway and the Emu Proof Fence.

• K: Allocasuarina acutivalvis, Melaleuca nematophylla and Grevillea obliquistigma shrubland over Cheilanthes adiantoides ferns.

This floristic group is represented by 74 quadrats which clearly cluster floristic compositions on ironstone ridges across the Mt Gibson ranges; five within the Iron Hill proposal and the remaining 69 from Extension Hill, Extension Hill North, Extension Hill South, Iron Hill North, Iron Hill East, and Mount Gibson North. Based on the ATA (2006b) quadrats this floristic unit is equivalent to mapped vegetation units T1 (33 quadrats), T3 (seven quadrats), T5 (three quadrats), T6 (eight quadrats), T12 (three quadrats) and M4 (one quadrat) as well as Community Type 6 (14 quadrats) and Community Type 4 (one quadrat) from the Meissner and Caruso (2008b) survey. The relatively large number of quadrats in this unit is a function of the high density of quadrats on the Mt Gibson Ranges.

Due to the large number of quadrats representing Floristic Group K, this group was divided further into three floristic subgroups to investigate finer-scale vegetation patterns. The subgroups are similar in species composition and many taxa are common to all three subgroups, but represented in different frequencies.

o K1: Calycopeplis pauciflorus, Leucopogon sp. Clyde Hill, Philotheca sericea, Allocasuarina acutivalvis subsp. prinsepiana, Eremophila clarkei, Grevillea paradoxa and Melaleuca nematophylla shrubland over Cheilanthes adiantoides ferns

This floristic subgroup is represented by 13 quadrats, four of which are from the ecologia 2015 survey, four from the Meissner and Caruso (2008b) assessment and five from the ATA (2006b) survey. Three quadrats from this subgroup are within the Iron Hill development envelope (ecologia quadrats 10, 11 and 12). Three of the Meissner and Caruso (2006b)

quadrats represent Community Type 6 and one represents Community Type 4. Floristic subgroup K1 is largely associated with Iron Hill with four quadrats inside and one just north of the Iron Hill development envelope, but there are also 6 quadrats on the north-east of Extension Hill and the remaining two quadrats are relatively isolated: one at Extension Hill South, and the other north of Mount Gibson.

o K2: Allocasuarina acutivalvis subsp. prinsepiana, Melaleuca nematophylla, Grevillea obliquistigma subsp. obliquistigma, Aluta aspera subsp. hesperia, Acacia assimilis subsp. assimilis and Philotheca sericea shrubland over Cheilanthes adiantoides ferns

This floristic subgroup is represented by 39 quadrats, 30 from the ATA (2006b) survey and nine from the Meissner and Caruso (2008b) assessment. No quadrats from this subgroup are within the Iron Hill development envelope. All nine of the Meissner and Caruso (2006b) quadrats represent Community Type 6. Floristic subgroup K2 is largely associated with Extension Hill, with 35 quadrats representing the subgroup from Extension Hill and the remaining four quadrats from Iron Hill East (two quadrats) and the lower slopes of Mount Gibson (two quadrats).

o K3: Allocasuarina acutivalvis subsp. prinsepiana, Grevillea obliquistigma subsp. obliquistigma, Calycopeplus pauciflorus, Melaleuca nematophylla, Grevillea paradaoxa and Philotheca sericea shrubland over Xanthosia kochii herbs and Cheilanthes adiantoides ferns

This floristic subgroup is represented by 22 quadrats, 20 of which are from the ATA (2006b) survey and two from the Meissner and Caruso (2008b) assessment. One quadrat from this subgroup is within the Iron Hill development envelope (ATA 45). Both of the Meissner and Caruso (2006b) quadrats represent Community Type 6. Floristic subgroup K3 appears to be generally associated with the higher peaks of the hills (but with some exceptions) and often near the Group E quadrats which is restricted to the steepest, most unstable slopes of the range. The quadrats are widely distributed across the range at Extension Hill, Extension Hill South, Iron Hill, Iron Hill North, Mt Gibson and Mount Gibson South.

• L: Eucalyptus oldfieldii open woodland over Allocasuarina acutivalvis subsp. prinsepiana, Aluta aspera subsp. hesperia, Enekbatus stowardii, Melaleuca fabri and Acacia coolgardiensis subsp. effusa shrubland over Amphipogon caricinus var. caricinus grassland and Cheilanthes adiantoides ferns.

This floristic group was not sampled in the ecologia (2015) assessment, but is composed of seven previously sampled quadrats: one ATA (2006b) quadrat (ATA 2) and six DEC (Meissner and Caruso 2008b) quadrats (MTGB03), MTGB05, MTGB07, MTGB11, MTGB16 and MTGB29). Five of the DEC quadrats constitute Community Type 6 (Meissner and Caruso 2008b) . All seven quadrats from this floristic group are associated with the Extension Hill section of the Mount Gibson Ranges on slopes and footslopes.

• M: The single quadrat from this group is located away from the Mount Gibson Ranges, at the Emu-proof fence.

All floristic groups as defined in this floristic analysis are also well represented by quadrats from outside the Iron Hill development envelope. This analysis shows: • The six floristic groups from within the proposed Iron Hill development footprint also occur

outside the proposed development footprint within the Mt Gibson Ranges or elsewhere; and • A clear distinction between ridge tops/slopes, foot slopes/flats and sandplains is evident in the

analysis.

Vegetation mapping from the floristic groups was extrapolated over areas where floristic quadrats were limited or absent, but where vegetation previously mapped by Bennett Environmental Consulting (2000) provides information on the vegetation present (Figure 3.3).

Within the proposed Iron Hill development envelope, Floristic Groups E, K and L are associated with the ironstone hills and slopes and are considered to be components of the Priority 1 Mount Gibson Range vegetation complexes (banded ironstone formation) PEC. Of these Floristic Groups considered to represent components of the PEC, quadrats representing Groups K and L are restricted to the Mount Gibson Ranges, whereas three of the quadrats representing Group E are present on a hill to the north of the Great Northern Highway, approximately 8 km north of the Mount Gibson Ranges and one quadrat at Yandhanoo Hills approximately 8 km north-east of the Mount Gibson Ranges (Figure 3.4).

3.2.2 Floristic Group Comparison with Previous Vegetation Assessments

The six floristic groups represented by quadrats within the Iron Hill development envelope are summarised in Table 3.1, and compared to the vegetation mapping completed by Bennett Environmental Consulting (2000) in Table 3.2. This enables the results of previous studies to inform this study in areas where floristic quadrats are limited or absent, In summary: • A: All five quadrats representing floristic group A are located within vegetation unit T9 of Bennett

Environmental Consulting (2000), although one quadrat is located on the boundary vegetation units T9 and M1. All five floristic group A quadrats are from the current field assessment.

• B: Quadrats representing floristic group B are located within vegetation unit M1 of Bennett Environmental Consulting (2000), although both floristic group B quadrats are from the current field assessment.

• C1: Four of the six quadrats representing floristic group C1 are located within vegetation unit M1 of Bennett Environmental Consulting (2000). The remaining quadrats are located in vegetation units T8 (one quadrat) and one quadrat is located outside the extent of Bennett Environmental Consulting (2000) vegetation mapping, near Yandhanoo Hills. This floristic group also includes two of the three DEC quadrats that represent DEC community 3 (Meissner and Caruso 2008b).

• C2: One of the five quadrats representing floristic group C2 is located within vegetation unit M1 of Bennett Environmental Consulting (2000), and one quadrat is located on the boundary of vegetation units M1 and T3. The remaining quadrats are located in vegetation unit T9 (two quadrats) and on the boundary of T10 and W5 (one quadrat). This floristic group also includes four of the five quadrats representing community 4 (Meissner and Caruso 2008b).

• E: Five of the 15 quadrats representing floristic group E are located within vegetation unit T3 of Bennett Environmental Consulting (2000). The other quadrats are located in related vegetation units: T5, T6, HS1 (two quadrats in each) and W2 (one quadrat to the east on Ninghan Station). Three additional quadrats are located outside the extent of the Bennett Environmental Consulting (2000) vegetation mapping. This floristic group also includes two of the ten DEC quadrats that represent DEC community 1 and all six quadrats representing community 5 (Meissner and Caruso 2008b).

• K: Thirty-nine of the 74 quadrats representing group K are located within vegetation unit T1 of Bennett Environmental Consulting (2000), 13 are from vegetation unit T3, which includes the quadrats on Iron Hill) and ten are from vegetation unit T6. The remaining quadrats are located in related vegetation units: T5, T12 and M4. This floristic group also includes 14 of the 15 DEC quadrats that represent community 6 and one quadrat representing community 4 (Meissner and Caruso 2008b). o K1: Five of the 13 quadrats from subgroup K1 are located within vegetation unit T3 of

Bennett Environmental Consulting (2000), three are from each of the vegetation units T1 and T12, and one from T6. An additional quadrat straddles the boundary of vegetation units T1 and T12. This floristic subgroup also includes three of the 15 DEC quadrats that represent community 6 and one quadrat representing community 4.

o K3: Nine of the 22 quadrats from subgroup K3 are located within vegetation unit T6 of Bennett Environmental Consulting (2000), five are from vegetation unit T1, four from T3, three from T5 and one from M4. This floristic subgroup also includes two of the 15 DEC quadrats that represent community 6 (Meissner and Caruso 2008b)



March 2016

21

Therefore, in the vicinity of Iron Hill and the Mount Gibson Ranges, the floristic groups are equivalent to the vegetation units of Bennett Environmental Consulting (2000) and community types of Meissner and Caruso (2008b) as follows: • Floristic group A is equivalent and a subset of vegetation unit T9 of Bennett Environmental

Consulting (2000), but being located away from the Mt Gibson Range, is not equivalent to any community of Meissner and Caruso (2008b).

• Floristic group B is equivalent to a subset of vegetation unit M1 of Bennett Environmental Consulting (2000), but being located away from the Mt Gibson Range, is not equivalent to any community of Meissner and Caruso (2008b).

• Floristic group C1 is equivalent to a subset of vegetation unit M1 of Bennett Environmental Consulting (2000), and equivalent to community 3 of Meissner and Caruso (2008b).

• Floristic group C2 is equivalent to a subset of vegetation unit M1 and unit T9 of Bennett Environmental Consulting (2000), and equivalent to community 4 of Meissner and Caruso (2008b).

• Floristic group E is mostly equivalent to a subset of vegetation unit T3 of Bennett Environmental Consulting (2000), and equivalent to community 5 of Meissner and Caruso (2008b).

• Floristic group K is equivalent to a subset of vegetation units T1 and T3 of Bennett Environmental Consulting (2000), but vegetation unit T1 is restricted to Extension Hill. Floristic group K is also equivalent to community 6 of Meissner and Caruso (2008b). o Floristic subgroup K1: is equivalent to a subset of vegetation T3 of Bennett Environmental

Consulting (2000) and a subset of community 6 of Meissner and Caruso (2008b). o Floristic subgroup K3: is equivalent to a subset of vegetation T6 of Bennett Environmental

Consulting (2000) and a subset of community 6 of Meissner and Caruso (2008b)

3.3 SURVEY LIMITATIONS

According to the EPA Guidance Statement (No. 51) for Terrestrial Flora and Vegetation Surveys for Environmental Impact Assessment (EIA) in Western Australia (EPA 2004), flora and vegetation surveys may be limited in several respects. An assessment of this study against these aspects is provided in Table 3.3.

Table 3.4 – Survey limitations

Aspect Comment

Sources of information and availability of contextual information (i.e. pre-existing background versus new material)

Flora and Vegetation Assessments previously completed at Mt Gibson, include: • Bennett Environmental Consulting (2000): Flora and Vegetation of Mt Gibson; • Armstrong (2004): Vegetation Assessment and Rare Flora Search between Perenjori and Mt

Gibson; • ATA (2006b) Mt Gibson Magnetite Project Supplementary Vegetation and Flora Surveys; and • Meissner and Caruso (2008b) Flora and vegetation of banded iron formations of the Yilgarn

Craton: Mount Gibson and surrounding area. In addition, numerous targeted flora surveys have been conducted at Mount Gibson, in particular for the Threatened (Vulnerable) Darwinia masonii and Lepidosperma gibsonii.

The scope (i.e. what life forms were sampled?)

The vascular flora of the study area was sampled in accordance with Guidance Statement 51.

Proportion of flora collected and identified (based on sampling, timing and intensity)

From the 17 new quadrats of the 2015 survey, 115 vascular flora taxa were recorded, which is 62.5% of the (Chao 2) estimated richness of 176 taxa. When the 50 DEC quadrats (Meissner and Caruso 2008b) and 100 ATA (2006b) quadrats were included, the data from all 167 quadrats yielded 184 taxa (77.3%) of an estimated total 238 taxa (Chao 2 Classic incidence-based richness estimator).

Completeness and further work which might be needed (e.g. was the relevant area fully surveyed?)

Sixteen quadrats have now been sampled within the study area, and all areas have been searched for Threatened and Priority flora at approximately 50 m search grids or finer, either from this assessment or previously (Eco Logical (2014) Mount Gibson Ranges Darwinia masonii Census).

Mapping reliability Aerial imagery was available and the number and distribution of quadrats was considered adequate for definition of vegetation within the study area. Vegetation mapping information from previous surveys was made available by Mt Gibson Mining.

Timing/weather/ season/ cycle

The survey was conducted in late April/early May 2015, following above average rainfall (53.9 mm of rain recorded at Mt Gibson (BOM Station: 010075) in March and 25.8 mm in April. Approximately 50% of taxa were recorded with reproductive material.

Disturbances (e.g. fire, flood, accidental human intervention)

Some sections of the Iron Hill proposal have been burnt in 2003, but not since that date. Previous mining and exploration activities are also widespread in the study area, but quadrat locations were selected outside the area of these disturbances.

Intensity (in retrospect, was the intensity adequate?)

Quadrats were distributed across the Iron Hill proposal at a density of 1 quadrat per 7 ha. The species accumulation curve suggests that approximately 62.5% of the taxa expected to be present in the study area were recorded in the 2015 survey, and 76.6% when data from all 167 quadrats were included.

Resources A total of 8 person days was expended, providing comprehensive coverage of the study area and regional data from adjacent areas.

Access problems Existing exploration tracks throughout the study area provided excellent access, with all parts of the study area readily accessible.

4 CONCLUSIONS With the inclusion of the 17 new quadrats surveyed in 2015 (eight within the proposed Iron Hill development envelope and nine in adjoining vegetation), five quadrats from Meissner and Caruso (2008b) and three from ATA (2006b) previously sampled, there are 16 quadrats within the proposed Iron Hill development envelope. This represents a high density of quadrats, approximately one quadrat every 7 hectares, which is considered sufficient to adequately describe the vegetation of the proposed Iron Hill development envelope. All quadrats from the proposed Iron Hill development envelope are 20 x 20 m in size and have been completed consistent with current guidelines.

The increased floristic sampling from quadrats and systematic transects in areas not previously covered in targeted flora searches provides satisfactory level of information for impact assessment on flora values of the proposed Iron Hill development envelope.

All six floristic units as defined in this analysis that are represented by quadrats within the Iron Hill development envelope are also represented by quadrats from outside the Iron Hill development envelope: • Floristic group A is represented across the sandplains to the west of Iron Hill, and is located

primarily within vegetation unit T9 of Bennett Environmental Consulting (2000). • Floristic group B is also represented across the sandplains to the west and south west of Iron

Hill, and is located within vegetation unit M1 of Bennett Environmental Consulting (2000). • Floristic group C1 is represented by quadrats on the colluvial plains west of Iron Hill, as well as

on similar landforms to the east of the Mt Gibson Ranges and near the Yandhanoo Hills. Most quadrats from this floristic group are located within vegetation unit M1 of Bennett Environmental Consulting (2000) and represents community 3 Meissner and Caruso (2008b).

• Floristic group C2 is represented on the footslopes west of Iron Hill, as well as on a similar low landforms to the east of Mt Gibson. Most quadrats from this floristic group are located within vegetation units M1 and T9 of Bennett Environmental Consulting (2000), and also represents community 4 of Meissner and Caruso (2008b).

• Floristic group E is represented on the nearby ridges at ‘Iron Hill North’ and ‘Mount Gibson’, in addition to ‘Iron Hill’. In the vicinity of the Iron Hill proposal, this floristic group is located within vegetation unit T3 of Bennett Environmental Consulting (2000), and also represents community 5 of Meissner and Caruso (2008b).

• Floristic group K is well represented across the ironstone ranges at ‘Extension Hill’, ‘Extension Hill North’, ‘Extension Hill South’, ‘Iron Hill North’, ‘Iron Hill East’, and ‘Mount Gibson North’ as well as at ‘Iron Hill’. In the vicinity of the Iron Hill proposal, this floristic group is located within vegetation unit T3 of Bennett Environmental Consulting (2000), and also represents community 6 of Meissner and Caruso (2008b). Floristic Group K was further divided into three subgroups of very similar floristic composition: o Floristic subgroup K1 is largely associated with Iron Hill with four quadrats inside and

one just north of the Iron Hill development envelope, but there are also 6 quadrats on the north-east of Extension Hill and the remaining two quadrats are relatively isolated: one at Extension Hill South, and the other north of Mount Gibson. This floristic subgroup is is equivalent to a subset of vegetation T3 of Bennett Environmental Consulting (2000) and a subset of community 6 of Meissner and Caruso (2008b).

o Floristic subgroup K3 appears to be generally associated with the higher peaks of the hills (but with some exceptions) and often near the Group E quadrats which is restricted to the steepest, most unstable slopes of the range. The quadrats are widely distributed across the range at Extension Hill, Extension Hill South, Iron Hill, Iron Hill North, Mt Gibson and Mount Gibson South. This floristic subgroup is equivalent to vegetation unit

T6 of Bennett Environmental Consulting (2000) and a subset of community 6 of Meissner and Caruso (2008b).

Three floristic groups (E, K and L) are considered to represent key components of the Priority 1 Mount Gibson Range vegetation complexes (banded ironstone formation) PEC, due to their association with ironstone range landforms. In the vicinity of Iron Hill, floristic groups E and K are approximately equivalent to the structural vegetation units T1 and T3 of Bennett Environmental Consulting (2000), which is also associated with the ironstone range, and equate to the DEC communities 5, 6 and 7 (Meissner and Caruso 2008b). Therefore the outer boundary of floristic groups E, K and L is considered to represent the key component of the PEC across the Mount Gibson Ranges.

In summary, Mt Gibson BIFs are generally similar in floristics to Tallering BIFs, whereas Extension Hill and most of the Iron Hill quadrats are more similar to

the BIFs of Koolanooka – Perenjori Hills, although there is some overlap (see grouping in middle of ordination)

Also note that the ATA quadrats on Mt Gibson, Extension Hill and Iron Hill BIFs are distinct from the DPaW quadrats in the same area – they are grouped to

the top‐left side of ordination (see labelling of sites below – you may need to zoom in to read labels, but the ATA quadrats have a ‘G’ prefix). It is unclear

why this is, but the ATA quadrats were floristically less rich than DPaWs (maybe sampled during dry spell?).
