Dear Todd

Re: Addendum to Stygofauna Assessment of Northern and Southern Borefields.

Background

Fortescue Metals Group (Fortescue) operates the Solomon iron ore mine, located 60 kilometres

(km) north of Tom Price in the Pilbara region of Western Australia. Solomon consists of two mining

areas, Kings and Firetail. Fortescue is currently investigating options to develop two new borefields

at Solomon: one approximately 12 km to the north-east of Firetail and one 12 km to the south-east

of Kings. They are known as the Northern Borefield and Southern Borefield, respectively.

Previously, a Level 2 survey in June and July 2014 collected and identified 13 stygofauna species

known only from the proposed borefield areas (Bennelongia 2014; Table 1). While the available

information suggested that 10 of these species probably have wider ranges, it appeared that three

species might have ranges that are mostly confined to the borefields. These species were the snail

Hydrobiidae sp. B06, the copepod Elaphoidella sp. B04 and the syncarid Bathynella sp. B16.

To assess the level of threat to these species, additional stygofauna sampling was undertaken

outside the proposed borefields. The specific objectives were to: i) demonstrate wider occurrence

of these target species outside the area of groundwater drawdown; and ii) evaluate the impact of

the proposed groundwater abstraction on these species.

Field and Laboratory Methods

Additional sampling at Solomon was conducted according to the approach laid out in

Environmental Assessment Guideline 12 and Guidance Statement No. 54A (EPA 2007, 2013) and

follows the procedures described in the previous report ‘Solomon: Stygofauna Assessment of

Northern and Southern Borefields’ (Bennelongia 2014).

A total of 38 stygofauna samples were collected from the vicinity of the proposed borefields

between 10 and 13 November 2014 (Appendix 1; Figure 1). This was in addition to the 80

stygofauna samples that were collected from 41 bores in June and July 2014 (Bennelongia 2014)

and 54 historical samples that had been collected previously during other surveys for Fortescue

undertaken by Ecologia (2013a, b) and Subterranean Ecology (2010, 2011). Twenty samples were

collected outside the Northern Borefield and 18 samples outside the Southern Borefield.

Sampling outside the Northern Borefield focussed on the tributaries of the Fortescue River and 18

samples were collected near Coolawanyah Airport, which is located c. 12-35 km northwest of the

Northern Survey Area. This area was sampled because two of the target species, Hydrobiidae sp.

B06 and Elaphoidella sp. B04, were known only from Old Millers Bore at the north side of the

groundwater drawdown area associated with the Northern Borefield (Bennelongia 2014). It was

considered possible that the two species may occur farther downstream in the Fortescue River

tributaries. Two additional samples were also taken from near the Fortescue Marsh in the Northern

Survey Area.

Sampling outside the Southern Borefield targeted the tributaries of Weelamurra Creek in the

vicinity of Mount Sheila, located c. 2-10 km northwest of the Southern Survey Area (Figure 1). This

area was sampled because the previous Level 2 survey had indicated the presence of a moderately

rich stygofauna community and the target species Bathynella sp. B16 was considered to be possibly

present.

Taxonomic identifications were based on morphological comparisons between the material

collected in June/July (Level 2 survey) and specimens collected in November 2014 (targeted survey).

Representative specimens of 11 stygofauna species collected by Subterranean Ecology in 2010 and

2011, but previously unavailable for study, were also examined as part of the identification process.

DNA analyses were carried out on seven specimens to refine identifications. These were three

amphipod specimens of the family Paramelitidae, two isopod specimen of the family

Microcerberidae, and two hydrobiid snail specimens. DNA sequences from these animals were

compared with the DNA data generated previously for specimens from the Solomon mine area.

Personnel

Fieldwork was undertaken by Jeremy Quartermaine and Jim Cocking. Samples were sorted by

Jeremy Quartermaine, Dean Main, Mike Scanlon and Danilo Harms. Identifications were made by

Jane McRae (copepods, syncarids and amphipods) and Stuart Halse (ostracods). DNA lab work and

analyses were undertaken by Danilo Harms.

Results

A total of 761 stygofauna specimens belonging to at least 41 species were collected during the

targeted survey. These comprised Nematoda (2 species), Rotifera (treated as 1 species),

Gastropoda (1), Aphanoneura (1), Oligochaeta (3), Ostracoda (9), Copepoda (12), Spelaeogriphacea


3

(1), Syncarida (1), Amphipoda (7) and Isopoda (3). The targeted survey brought the total number of

stygofauna specimens collected from the proposed borefields and surrounds (see Figure 1) to 3153,

which represents at least 83 species (Appendix 2).

Target species

The results of the previous Level 2 stygofauna survey (Bennelongia 2014) suggested that the snail

Hydrobiidae sp. B06, the copepod Elaphoidella sp. B04 and the syncarid Bathynella sp. B16 might

be restricted to the proposed areas of groundwater drawdown in the borefields.

Targeted sampling showed wider distribution of one of these three species (Hydroiidae sp. B06).

The other two species (Elaphoidella sp. B04 and Bathynella sp. B16) remain known only from within

the borefields. In the case of Elaphoidella sp. CP1, however, we were unable to determine whether

it had been re-collected (with a range extending outside the proposed borefields) because the only

specimens of this species have been lodged in Crustacea collections of the Western Australian

Museum and cannot be found (Andrew Hosie, pers. com.). Elaphoidella sp. B07, which is known

only 3 km to the north and outside the proposed borefields, may be the same species as

Elaphoidella sp. CP1. This would mean two of the three potentially restricted species have been

shown to have distributions extending beyond the borefields.

The range extension of Hyrobiidae sp. B06 was quite dramatic. The species was previously known

only from a single specimen in the Northern Borefield but additional sampling yielded 64 additional

specimens from bores CPM0205 and TRRDR23 in the vicinity of the Southern Borefield (Figure 2B),

which is a range extension of 36 km. The identification of these animals as the same species is

based on morphology because, although amplification of DNA was successful for a specimen from

bore CPM0205 during the targeted survey, no DNA was obtained from the single specimen

collected during the Level 2 survey (Bennelongia 2014).

Other species recorded only from the borefields

Wider ranges because of improved identifications have also been shown for three of the other 10

stygofauna species previously known only from the borefields (Table 1) but predicted in

Bennelongia (2014) to have wider ranges. These are the ostracods Candoninae sp. BOS406 and

Candoninae sp. BOS407 and the copepod Harpacticoida sp. CP1.

Additional specimens showed that the ostracod species Candoninae sp. BOS406 and Candoninae

sp. BOS407 are conspecific with Areacandona sp. BOS387, which is a widespread species with a

linear range of 44 km (Figure 2A). Candoninae sp. BOS406 and Candoninae sp. BOS407 were

previously represented by valve fragments and positive identification of Areacandona species

usually requires morphological details that are only visible if specimens are collected alive (e.g.

Karanovic, 2005).

The copepod Harpacticoida sp. CP1 was collected and identified by Subterranean Ecology in 2010.

After specimens were provided to Bennelongia, it was determined that Harpacticoida sp. CP1 was

the same species as Australocamptus sp. B11, which has been collected 29 km away at Mt MacLeod

to the south of the Southern Borefield (Figure 2B).

Current conservation status of species

As a result of targeted sampling and some taxonomic refinement, four species previously collected

only from the borefields are now known to be more widespread (Table 2). The snail Hydrobiidae

sp. B06 has a linear range of at least 36 km and the copepod Australocamptus sp. B11 (previously

Harpacticoida sp. CP1) has a range of at least 29 km. Both species have been recorded outside the

borefields. The ostracod fragments previously referred to as Candoninae sp. BOS406 and

Candoninae sp. BOS407 belong to the widespread species Areacandona sp. BOS387, which a range


4

of 45 km or more and occurs at multiple sites outside the borefields. It is also possible that

Elaphoidella sp. CP1 was collected outside the proposed borefields (as Elaphoidella sp. B07).

The number of species known only from the proposed areas of groundwater drawdown was

reduced by at least 31% after targeted sampling that represented only 22% of all sampling effort in

the vicinity. Based on the fact that the previously restricted species now shown to be widespread

have linear ranges of 30-45 km, it appears likely that all nine species known only from the

borefields are likely to have ranges extending beyond the Northern Borefield and Southern

Borefield. None of the single records of these species is more than 2.5 km from the edge of

groundwater drawdown (Figures 2 and 3). Perhaps most significantly, no species known from two

or more bores is restricted to the proposed areas of groundwater drawdown, which strongly

suggests that apparently restricted ranges are an artefact of sampling.

These sampling artefacts do not reflect low survey effort because 172 stygofauna samples have

been collected for this assessment. Instead, it probably reflects a patchy distribution and low

abundance of the apparently restricted species. Accordingly, we suggest that it is now appropriate

to consider that all nine species known only from the proposed areas of groundwater drawdown

are unlikely to be restricted to these areas of drawdown.
