Andersonia gracilis (T-DRF (VU)) is a slender, erect or open straggly shrub, growing to 0.5
m in height with white to pink / purple flowers present from September to November (Plate
1). This species generally occurs on white to grey sand, sandy clay and gravelly loam, often
in winter-wet areas or near swamps (DPaW 2013a). Andersonia gracilis has a geographical
distribution of approximately 110 km occurring from Cooljarloo to Gingin, with outliers in
the Perth Region. There are currently 29 populations for this taxon recorded within DPaW
databases (Woodman Environmental 2013d). Andersonia gracilis is ranked as Vulnerable
under the WC Act, and Endangered under the EPBC Act.
At the completion of studies for this project, Andersonia gracilis is now known from 1094
point locations representing 39 populations in the Study Area (Appendix H, Figure 7.1).
Although this taxon has been recorded in seven VTs (as well as in areas now mapped as
Cleared, and rehabilitated areas), the preferred VTs are 5, 2 and 1 (546, 233 and 212 locations
respectively) (Appendix H; Figure 7.1).

Anigozanthos viridis subsp. terraspectans (T-DRF (VU)) is a rhizomatous, perennial herb
growing to 0.2 m in height occurring on grey sand and clay loam in winter-wet depressions,
with green and yellow flowers from August to September (Plate 2). It has a known
geographical distribution of approximately 100 km, with approximately 17 populations
recorded in DPaW databases (Woodman Environmental 2013d). Anigozanthos viridis subsp.
terraspectans is ranked as Vulnerable under both the WC Act and the EPBC Act.
At the completion of studies for this project, Anigozanthos viridis subsp. terraspectans is now
known from 57 point locations representing 22 populations in the Study Area (Appendix H,
Figure 7.1). The preferred habitat for this taxon is VT 1, in which 27 locations are located
(Appendix I). An indeterminate specimen was also recorded at two point locations (two
separate populations) within the Study Area, both of which are also located in VT 1
(Appendix H; Figure 7.1).

Eremophila glabra subsp. chlorella (T-DRF) is no longer believed to be the entity occurring
at Cooljarloo. Review of the collected material by the WAHerb shows atypical characters for
subsp. carnosa in having yellow corollas ageing red, and at least sometimes hairy young
growth (cf. bright red corollas and always glabrous leaves and branchlets). This specimen is
best referred to as subsp. ?carnosa until further investigation is undertaken. The species
should be regarded as taxonomically significant and, as such efforts made to conserve the
populations due to its anomalous morphology (M. Hislop pers. comm. 2013).
Eremophila glabra subsp. carnosa is an erect slender shrub, growing to 0.7 m high (Plate 3),
generally occurring on white/grey sand in intermittently damp areas. Eremophila glabra
subsp. ?carnosa is known from 2 point locations representing two separate populations in the
Study Area, both occurring in VT 2 (Appendix H; Figure 7.5).

Macarthuria keigheryi (T-DRF(VU)) is an erect or spreading perennial herb or shrub growing
to 0.4 m high and 0.6 m wide, flowering from September to December or February to March
(Plate 4) and generally occurs on white or grey sand (DPaW 2013a). It has a geographical
distribution of approximately 180 km from Cooljarloo to Kenwick (Perth), with a total of 12
populations recorded in DPaW databases (Woodman Environmental 2013d). Macarthuria
keigheryi is ranked as Endangered under both the WC Act and the EPBC Act.
At the completion of studies for this project, Macarthuria keigheryi is now known from 157
point locations representing 24 populations in the Study Area (Appendix H, Figure 7.1). The
preferred habitat for this taxon is VTs 17 and 18, with 84 and 53 locations recorded in these
VTs respectively.

Paracaleana dixonii (T-DRF (VU)) is a tuberous, perennial herb growing to 0.2 m high, with
1-2 yellow-brown duck-like flowers from October to December or January (Plate 5). It
generally occurs on grey sand over granite (DPaW 2013a), and has a geographical range of
approximately 245 km with 26 populations recorded in DPaW databases (Woodman
Environmental 2013b; with one additional population at Cooljarloo to that recorded in this
report). Paracaleana dixonii is ranked as Vulnerable under the WC Act, and Endangered
under the EPBC Act.
Paracaleana dixonii was recorded by Astron Environmental from a single point location (one
population) in the Study Area in December 2012 (Appendix H, Figure 7.1). This timing is out
of the normal flowering season for this taxon (late October – November), and this may be the
reason why this taxon has not been recorded earlier, or in more localities at Cooljarloo, as
many of the surveys for CS flora taxa in the Study Area have been undertaken during the
prime surveying months in Spring (August – October).
The record of this taxon was collected in VT 17, which is characterised by mixed Banksia and
Eucalyptus todtiana woodland on plains and undulating dunes of white sand. This taxon
prefers deep sand in open areas, beneath dense tall shrubs including Banksia, or shallow sand
over laterite in heathland (Brown et al. 2008). This taxon has the potential to be more widely
distributed through the Study Area, primarily in VTs 7 (due to sand over lateritic influence),
17 and 18.

Andersonia gracilis, Macarthuria keigheryii and Paracaleana dixonii are also listed as
Threatened – Endangered under the Commonwealth EPBC Act. Likewise, Anigozanthos
viridis subsp. terraspectans is listed as Threatened – Vulnerable under the EPBC Act.

Range Extensions and Distribution Gaps
As the Study Area is situated near the junction of three IBRA subregions (Figure 5), a large
number of taxa recorded in the Study Area correlate to range extensions, represent new
localities (within the known ranges) or represent taxa with few vouchered collections at the
WAHerb.
Table 10 presents the CS flora taxa where the collections or records from the Study Area
represent extensions to the known distribution, or otherwise fill gaps within the known
distribution of such taxa. Appendix J similarly presents common taxa recorded from the
Study Area that represent extensions to the known distribution, or otherwise fill gaps within
the known distribution of such taxa.

4.1.3 Introduced Taxa
A total of 93 discrete introduced flora taxa have been recorded in the Study Area (Table 11).
Table 11 also presents ratings for each of these taxa as per the Environmental Weed Strategy
for Western Australia (Appendix D) (CALM 1999), as well as the number of locations and
vegetation types which each taxon was recorded. Locations of each of these flora taxa are
presented in Appendix K, and shown on Figure 8. The source data of these taxa and location
records has been taken from all historical studies summarised in Table 3 (where specific
locational data is available). A dash (‘-’) indicates that there was no point location data
available and therefore the VT in which they occur is unknown.
While a large number of introduced taxa occur within the Study Area, many are common
weeds of the Swan Coastal Plain (Hussey et al. 2007), and the majority were ranked as
‘Moderate’ or lower under the Environmental Weed Strategy for Western Australia (CALM
1999). A total of five taxa were ranked as ‘High’ under this strategy, and descriptions of
these taxa are presented in Appendix L.
