FLORA OF LOCAL SIGNIFICANCE
Priority Flora are of local significance when their presence is confined to a specialised habitat type
that is not common in the local area and whose disturbance or removal may lead to local extinction.
Table 8.2 shows the total known distribution and abundance for each species recorded and the
subsequent percentage of this total in the Study Area. The conservation significance of each species
recorded in the Study Area is discussed below.
Priority 1 Flora
Acacia lineolata subsp. multilineata has been recorded in the Geraldton Sandplains and Avon
Wheatbelt bioregions and is known from 85 individuals at 16 locations. In the Study Area, ten
individuals were recorded at one location (12% of the total known individuals). This species is not a
widely known species and has a moderate amount of the total known individuals in the Study Area.
However, as this species has been recorded in two bioregions, and its distribution spans 135 km, it is
not locally endemic and it has moderate local conservation significance.
Acacia sp. Jack Hills (R. Meissner & Y. Caruso 4) has only been recorded in the Murchison bioregion
and is known from 1,318 individuals at 95 locations. In the Study Area, one individual was recorded
at one location (<1% of the total known individuals). This species is not very common in the Study
Area and impact to it will not result in any significant loss to the species, it therefore has low(a)
conservation significance.
Baeckea staminosa has only been recorded in the Geraldton Sandplains bioregion and is known from
five individuals at five locations. In the Study Area, one individual was recorded at one location
(20% of the total known individuals). Baeckea staminosa is not a widely known species (the total

known distribution spans 55 km) and a large amount of the known population is recorded in the
Study Area. Any impact could have a significant result on the species and therefore has high(b)
conservation significance.
Chamelaucium sp. Yalgoo (Y. Chadwick 1816) has only been recorded in the Geraldton Sandplains
bioregion and is known from 22 individuals at seven locations. In the Study Area, three individuals
were recorded at two locations (14% of the total known individuals). Chamelaucium sp. Yalgoo is not
a widely known species and a large amount of the known population is recorded in the Study Area.
Any impact could have a significant result to the species and therefore has moderate conservation
significance. As this is not a fully described species, it is possible that it is not a rare in the local area
(the total known distribution spans 185 km), but poorly collected, however as this is not known the
former should be assumed.
Eremophila sp. Tallering (J.D. Start & M.J. Greeve D 516) has been recorded in the Geraldton
Sandplains and Yalgoo bioregions and is known from 123 individuals at nine locations and seven
populations, none of which are in conservation reserves. In the Study Area, 25 individuals were
recorded at two locations (20% of the total known individuals). Eremophila sp. Tallering is not a
widely known species and a large amount of the known population is recorded in the Study Area.
Any impact could have a significant result to the species and therefore has high(b) conservation
significance. As this is not a fully described species, it is possible that it is not a rare in the local area
(the total known distribution spans 75 km), but poorly collected, however as this is not known the
former should be assumed.
Euphorbia sarcostemmoides has been recorded in the Murchison and Gascoyne bioregions and is
known from 318 individuals at 68 locations. In the Study Area, 307 individuals were recorded at 65
locations (97% of the total known individuals). This species was widely recorded across the Study
Area and because of this, despite the large percentage of the total species population in the Study
Area; it is likely to be poorly collected, rather than locally endemic (the total known distribution
spans 400 km) and therefore has low(b) conservation significance.
Goodenia lyrata has been recorded in the Murchison, Gibson Desert and Pilbara bioregions and is
known from 56 individuals at 10 locations. In the Study Area, 40 individuals were recorded at three
locations (71% of the total known individuals). Goodenia lyrata is not a widely known species and a
very large amount of the known population is recorded in the Study Area. However, as this species
has been recorded in three bioregions, it is likely that it is more widespread that what is known (the
total known distribution spans 620 km) and is not locally endemic. It therefore has high(a)
conservation significance.
Gunniopsis divisa has been recorded in the Murchison and Yalgoo bioregions and is known from
1,168 individuals at nine locations. In the Study Area, 1000 individuals were recorded at one
location (86% of the total known individuals). Gunniopsis divisa is not a widely known species (the
total known distribution spans 125 km) and a very large amount of the known population is recorded
in the Study Area and any impact could have a significant result to the species and therefore has
high(a) conservation significance.
Harperia ferruginipes has been recorded in the Geraldton Sandplains bioregion and is known from 29
individuals at seven locations. In the Study Area, four individuals were recorded at three locations
(14% of the total known individuals). Harperia ferruginipes is not a widely known species (the total
known distribution spans 33 km, with an outlier to 160 km) and a large amount of the known
population is recorded in the Study Area. Any impact could have a significant result to the species
and therefore has high(b) conservation significance.
Lepidobolus basiflorus has been recorded in the Geraldton Sandplains bioregion and is known from
51 individuals at two locations. In the Study Area, one individual was recorded at one location (2%

of the total known individuals). This species is not very common in the Study Area and impact to it
will not result in any significant loss to the species, it therefore has low(a) conservation significance.
Lepidosperma sp. Moresby Range (R.J. Cranfield 2751) has been recorded in the Geraldton
Sandplains bioregion and is known from 176 individuals at 22 locations. In the Study Area, 139
individuals were recorded at 16 locations (79% of the total known individuals). This species appears
to be restricted to the Moresby Range area, and the large percentage of total population within the
Study Area in this case likely indicates a high local endemism in this area (the total known
distribution spans 20 km). Any Impact to this species is likely to significantly affect species numbers
and therefore has high(c) conservation significance.
Leucopogon psammophilus has been recorded in the Geraldton Sandplains bioregion and is known
from 72 individuals at 13 locations. In the Study Area, 10 individuals were recorded at one location
(14% of the total known individuals). Leucopogon psammophilus is not a widely known species (the
total known distribution spans 110 km) and a large amount of the known population is recorded in
the Study Area. Any impact could have a significant result to the species and therefore has moderate
conservation significance.
Melaleuca huttensis has been recorded in the Geraldton Sandplains bioregion and is known from
4,976 individuals at 644 locations. In the Study Area, 63 individuals were recorded at three
locations (1.3% of the total known individuals). This species is not very common in the Study Area
and impact to it will not result in any significant loss to the species, it therefore has low(a)
conservation significance.
Mirbelia ternata has been recorded in the Avon Wheatbelt bioregion and is known from seven
individuals at five locations. In the Study Area, three individuals were recorded at three locations
(43% of the total known individuals). Mirbelia ternata is not a widely known species (the total known
distribution spans 128 km) and a very large amount of the known population is recorded in the Study
Area. Any impact could have a significant result to the species and therefore has high(a)
conservation significance.
Petrophile vana has been recorded in the Murchison and Yalgoo bioregions and is known from 230
individuals at 14 locations. In the Study Area, 144 individuals were recorded at eight locations (63%
of the total known individuals). Petrophile vana is not a widely known species (the total known
distribution spans 100 km) and a large amount of the known population is recorded in the Study
Area. Any impact could have a significant result to the species and therefore has high(a)
conservation significance.
Ptilotus tetrandrus has been recorded in the Murchison and Little Sandy Desert bioregions and is
known from two individuals at two locations. In the Study Area, two individuals were recorded at
two locations (100% of the total known individuals). Ptilotus tetrandrus is not a widely known
species (the total known distribution spans 350 km) and a very large amount of the known
population is recorded in the Study Area. Any impact could have a significant result to the species
and therefore has high(a) conservation significance.
Sauropus sp. Woolgorong (M. Officer s.n. 10/8/94) has been recorded in the Murchison and Yalgoo
bioregions and is known from 168 individuals at 26 locations. In the Study Area, 51 individuals were
recorded at 15 locations (30% of the total known individuals). This species was widely recorded
across the Study Area and because of this, despite the large percentage of the total species
population in the Study Area; it is likely to be poorly collected, rather than locally endemic (the total
known distribution spans 280 km) and therefore has low(b) conservation significance.
Scholtzia sp. Binnu (M.E. Trudgen 2218) has been recorded in the Geraldton Sandplains bioregion
and is known from 212 individuals at seven locations. In the Study Area, 20 individuals were
recorded at one location (9% of the total known individuals). This species is not very common in the

Study Area and impact to it will not result in any significant loss to the species, it therefore has low(a)
conservation significance.
Scholtzia sp. Valentine Road (S. Patrick 2142) has been recorded in the Geraldton Sandplains
bioregion and is known from 13 individuals at two locations. In the Study Area, 13 individuals were
recorded at two locations (100% of the total known individuals). Scholtzia sp. Valentine Road is not a
widely known species (only one record is known) and an almost all of the known individuals have
been recorded in the Study Area. Any impact could have a significant result to the species and
therefore has high(a) conservation significance. As this is not a fully described species, it is possible
that it is not a rare in the local area, but poorly collected, however as this is not known, the former
should be assumed.
Tricoryne sp. Geraldton (G.J. Keighery 10461) has been recorded in the Geraldton Sandplains
bioregion and is known from 28 individuals at four locations. In the Study Area, 11 individuals were
recorded at one location (39% of the total known individuals). Tricoryne sp. Geraldton is not a widely
known species (the total known distribution spans 30 km) and a large amount of the known
population is recorded in the Study Area. Any impact could have a significant result to the species
and therefore has high(b) conservation significance. As this is not a fully described species, it is
possible that it is not a rare in the local area, but poorly collected, however as this is not known, the
former should be assumed.
Vittadinia cervicularis var . occidentalis has been recorded in the Geraldton Sandplains and Avon
Wheatbelt bioregions and is known from six individuals at five locations. In the Study Area, two
individuals were recorded at one location (33% of the total known individuals). Vittadinia cervicularis
var. occidentalis is not a widely known species (the total known distribution spans 40 km, with an
outlier to 150 km) and a large amount of the known population is recorded in the Study Area. Any
impact could have a significant result to the species and therefore has high(a) conservation
significance.
Priority 2 Flora
Acacia megacephala has been recorded in the Geraldton Sandplain bioregion and is known from 162
individuals at 20 locations. In the Study Area, two individuals were recorded at one location (1% of
