SPRING RARE FLORA SEARCH
LOTS 81, 99, 52, 51 AND 50 on NORTH SIDE OF TOODYAY ROAD
BETWEEN REEN AND RESERVE ROADS
GIDGEGANNUP, CITY OF SWAN
1.0 INTRODUCTION
This report describes methods and presents results of spring searches for rare flora in the Lots
81, 99, 52, 51 and 50 that are on the north side of Toodyay Road between Reen and Reserve
Roads, Gidgegannup. The principal objective of this project was to search for Threatened
(EPBC-listed), Declared Rare and Priority Flora.
These lots are referred to in this report as ‘the search area’.
1.1
LOCATION
The Gidgegannup search area is approximately 35 km north-east of Perth. It is in the area on
the north side of Toodyay Road between the northern ends of Stoneville and Bunning Roads.
It borders The Springs Road, Toodyay Road, Reen Road (the southern 1.5 km of which is
shown on some maps as Wilson Street) and Reserve Road. It is approximately 1.8 km wide,
between 1 km and 0.5 km deep and 186 ha in area.
The street addresses of the lots are 102 Reen Rd. (Lot 81), 39 The Springs Rd. (Lot 99), 1949
Toodyay Rd. (Lot 52), 1951 Toodyay Rd. (Lot 51) and 43 Reserve Rd. (Lot 50). Landgate
(2009) uses these street numbers, rather than lot numbers, on its Property Finder Hybrid
imagery.
1.2 OBJECTIVES
The aim of the search was to find any plants of Declared Rare and Priority Flora that might be
in the search area and to record locations of any found. In particular, we looked for the DRF
Thelymitra dedmaniarum (Cinnamon Sun Orchid) and other flora listed in Appendix A of this
report. These are the Declared Rare Flora (R, DRF) and Priority Flora (P) listed in results of
Department of Environment and Conservation (DEC) searches of relevant DEC flora
databases and in results of searches of relevant EPBC Act Protected Matters databases with
the DEWHA EPBC Act Protected Matters Search Tool.
The EPA’s Guidance No. 51 (Environmental Protection Authority 2004) advises that the most
appropriate time for a primary flora survey is when the majority of the plant species,
especially ephemerals and geophytes, in an area are flowering, fruiting and have foliage that
allows identification. For a Level 2 search for rare flora the Guidance specifies ‘one or more
visit/s in the main flowering season’, which is usually, but not always, spring. The October-
November period would probably be the best time for the Gidgegannup search area because
the two Declared Rare orchids to be searched for there are most likely to be in flower, and
identifiable, then.

1.3 REGIONAL SETTING
Beard shows the Gidgegannup area as being in the north-western part of the Dale
[phytogeographic] Subdistrict (Beard 1980), and, in Beard (1990, 1981, 1980, 1979a), he
briefly describes the subdistrict’s climate, geology, landforms, soils, vegetation and flora.
There are vegetation maps in [or accompanying] Beard (1981, 1979a) at scales of 1:1 000 000
and 1:250 000, respectively.
1.3.1 Climate
With winter rainfall and a bioclimatic dry season, when precipitation is less than the amount
required to maintain plant growth, calculated to be five to six months long, the Gidgegannup
climate can be classified as Dry Mediterranean or warm mediterranean. It is shown as the
former in Beard (1990, Fig. 2.8; 1981, Figs. 8, 9) and described as the latter in Beard (1980, p.
54).
The nearest Bureau of Meteorology stations in the Dale Subdistrict are Kalamunda (closed in
1994) and Bickley, where the mean annual rainfalls are 1065 mm (Kalamunda 1908-1993)
and 1109 mm (Bickley 1969-2009). The mean annual rainfall in Gidgegannup is probably less
than 1000 mm because, as shown by rainfall maps in Beard (1979a and b, Figs. 1), mean
annual rainfall on the Darling Plateau decreases northwards from Bickley.
1.3.2
Landforms and Soils
The 1:250 000 scale Landforms and Soils Perth sheet by Churchward and McArthur (1980)
shows the search area as having two Darling Plateau units: the Lateritic Uplands Dwellingup
(D) unit and the Minor Valleys Yarragil (Yg) unit. The Yg unit is in the northern part of Lot
50 and near the southern edges of the other lots in the search area. The D unit is in the rest of
the search area.
All of the Darling Plateau uplands on the Perth sheet south of Avon River and to as far east as
Wooroloo are mapped as D and Yg units, and the slopes and floors of most Darling Plateau
major valleys in that area are mapped as the Murray (My) unit.
1.3.3
Vegetation
Beard (1981, 1979a) shows, at scales of 1:1 000 000 and 1:250 000, the vegetation of the
Gidgegannup area and beyond it to be Jarrah-marri (Eucalyptus marginata – Corymbia
(Eucalyptus) calophylla) forest (e
2
3
Mc) in the western sector of the Dale Subdistrict. There is
Blackbutt ( Eucalyptus patens) in valleys, while Bullich ( Eucalyptus megacarpa) and
Taxandria ( Agonis) linearifolia are in swampy bottomlands.
The 1:250 000 scale Vegetation Perth sheet by Heddle et al. (1980) shows the search area as
having two Darling Plateau vegetation complexes: the Dwellingup Complex in Medium to
High Rainfall (Mapping Unit 2) and the Yarragil Complex (Minimum Development Swamps)
in Medium to High Rainfall (Mapping Unit 10). Vegetation Complex 10 is in the northern
part of Lot 50 and near the southern edges of the other lots in the search area. Vegetation
Complex 2 is in the rest of the search area.
3
Spring Rare Flora Searches, Lots 81, 99, 52, 51, 50 Toodyay Rd, Gidgegannup ASW 3/02/10
The vegetation of Vegetation Complex 2 and the upper slopes of Vegetation Complex 10 is
characteristically Eucalyptus marginata – Corymbia calophylla Open Forest, with Eucalyptus
patens and E. megacarpa on the valley floors of Vegetation Complex 10.
All of the Darling Plateau uplands on the Perth sheet south of Avon River and to as far east as
Wooroloo are mapped as Vegetation Complexes 2 and 10, and the slopes and floors of most
Darling Plateau major valleys in that area are mapped as the Murray and Bindoon Complex in
Low to Medium Rainfall (Mapping Unit 21).
1.3.4
Flora
Beard (1979a, 1981, 1990) lists some characteristic flora of the Darling System and Heddle et
al. (1980, Tables 3.2 and 3.4) lists the species that define Northern Jarrah Forest site-
vegetation types (Table 3.2) and which vegetation complexes these site-vegetation types are
in (Table 3.4). The Heddle et al. Table 3.2 is from Havel (1975), the same source and
essentially the same table as Table II in Beard (1979a).
The species, and other taxa, listed in the first two columns of Table A1, in Appendix A, are
Declared Rare and Priority Flora that have been recorded in Gidgegannup and nearby.
2.0
METHODS
2.1 PREPARATION FOR FIELD WORK
Prior to beginning searches in the field, two sets of databases were searched for Priority,
Declared Rare and Threatened Flora recorded within Gidgegannup and nearby. Department
of Environment and Conservation (DEC) staff were requested to search three DEC flora
databases for Priority and Declared Rare Flora, and the Department of the Environment,
Water, Heritage and the Arts (DEWHA) EPBC Act Protected Matters Search Tool was used
to generate a report listing Threatened (EPBC-listed) Flora. The names of the databases
searched, the parameters used for the searches and the results of the searches are given in
Appendix A.
Appendix A's Table A1 lists the 46 species of Declared Rare and Priority Flora that are in the
results of the 2009 DEC database searches, plus two additional EPBC-listed species. The
table gives information about conservation codes for the Declared Rare, Priority and
Threatened Flora listed and their distributions, localities, growth forms, habitats and flowering
times. The information in the table was compiled from Atkins (2008), FloraBase (2009),
Paczkowska and Chapman (2000), Grieve (1998), Marchant et al. (1987), Hoffman and
Brown (1998) and Brown et al. (1998), other references, herbarium specimens and personal
observations.
During preparation of the table, herbarium specimens in the Western Australian Herbarium
(WAH) and entries in the WAH’s FloraBase of taxa (species, subspecies, varieties) listed in
the table were examined for familiarisation with their appearance, habitats, distribution and
flowering times.

2.2 FIELD WORK
The field work component of the study, searches for rare flora, was undertaken by botanist
Dr. Arthur Weston on 8 and 9 November 2009. He had an assistant on the first day and, on
the second day, he visited a nearby reserved known population of the principal species
searched for, the DRF orchid Thelymitra dedmaniarum (Cinnamon Sun Orchid), to confirm
that it was in flower and identifiable. It was, but on substrates and vegetation units not
represented in the Gidgegannup search area.
Lots 81, 99, 52 and 50 were searched on-site by car and on foot, and Lot 51 was searched
from north and south of the lot and from the neighbouring Lots 50 and 52, with the aid of
binoculars.
The principal taxa (species, subspecies, varieties) searched for, including Thelymitra
dedmaniarum, are those listed in Table A1, but other Declared Rare and Priority Flora taxa
and otherwise significant flora, especially those listed in Atkins (2008), were also searched
for.
Specimens of plants not readily identifiable in the field, or with help from keys and
descriptions in floras and articles, were collected for subsequent identification. Voucher
specimens of uncommon and possibly significant plants were also collected and pressed.
2.3 AFTER FIELD WORK
After returning from field work, pressing of plant specimens collected during the field work
was completed, and the pressed specimens were dried. The specimens were identified by
checking them against FloraBase (2009), a variety of keys and descriptions in floras and
taxonomic works, only some of which are referred to in this report, by consulting other
botanists, and, after fumigation, by comparing them with specimens in collections in the
Western Australian Herbarium in South Perth.
During the process of identification and following it, the names of the plants identified were
checked against Table A1 and other lists of significant flora, especially in Atkins (2008).
3.0 RESULTS AND DISCUSSION
3.1 VEGETATION AND HABITATS
Most of the search area is cleared or parkland cleared Jarrah and Marri on uplands of sandy
loamy soils, often with pisolytic gravel and, in some places, surface laterite. In some areas
there are sparse understoreys of native plants, among alien grasses and forbs. Balga
(Xanthorrhoea preissii) is in some of these understories, and Parrotbush (Banksia (formerly
Dryandra) sessilis) is in a few.
The interior of the northwest part of Lot 51 has an outcrop of rock 1 m to 2 m or more in
height bordered by degraded or completely degraded Jarrah and/or Marri woodland to forest.
5
Spring Rare Flora Searches, Lots 81, 99, 52, 51, 50 Toodyay Rd, Gidgegannup ASW 3/02/10
There is also a small area of Wandoo (Eucalyptus wandoo) in the north-western part of Lot
50, a stand of young Flooded Gum (Eucalyptus rudis) southeast of the Wandoo and a small
stand of what is probably Wandoo, but may be Bullich, in the southern quarter of Lot 51.
There are low-lying areas that are wet, at least seasonally, in the centre of the southern third
of Lot 81, in the centres of Lots 99 and 52, in the southern half of Lot 51 and in parts of the
northern half of Lot 50. There are few, if any, native plants other than Juncus pallidus in most
of these wetlands in Lots 99, 52 and 51. There is a stream along the southern boundary of Lot
81 and in the southwest corner of Lot 99, and there are dams in some of the lots.
The vegetation of the wet area and along the stream in Lot 81 is dominated by Taxandria
(formerly Agonis) linearifolia, with some Melaleuca paperbarks, and the wetlands in the
northern half of Lot 50 have a variety of vegetation. The most common or conspicuous
dominants in the Lot 50 wetlands are Flooded Gum (Eucalyptus rudis), Variable-leaved
Hakea (Hakea varia) and Astartea ?scoparia. The wetland at Waypoint 676 (50 J 422900 mE
6482813 mN) has a population of ‘belly’ plants, with small plants of several native species in
Drosera, Stylidium, Levenhookia, Centrolepis, Goodenia and other genera.
3.2
FLORA
No species or other taxon of Threatened, Declared Rare or Priority Flora was found during the
fieldwork, but the southern wetlands in Lot 81 or the northern wetlands in Lot 50 might
possibly have habitat for Drosera occidentalis subsp. occidentalis (P4) or other ephemeral or
geophytic Priority flora. In the unlikely event that there is suitable habitat, it is more likely to
be in Lot 50 at Waypoint 676 (50 J 422900 mE 6482813 mN), or east of it, than elsewhere.
It is unlikely that any plants of Drosera occidentalis subsp. occidentalis would have been in
flower at the time of the rare flora search, but they would have been in leaf. However, no
leaves thought to belong to Drosera occidentalis subsp. occidentalis were seen.
3.3
LIMITATIONS
No attempt was made to record all of the taxa in the project area, and it is likely that some,
especially geophytes and early- or late-flowering ephemeral herbaceous plants, were not seen.
Some species may occur in the project area but be identifiable at a different season or only
rarely; e.g. only during the first spring or two after a fire. And the occurrence and intensity of
flowering of many species varies from year to year. For instance, a known, reserved
population of the DRF orchid Thelymitra dedmaniarum (Cinnamon Sun Orchid), was in
flower and identifiable, but the plants and flowers were in smaller numbers and more poorly
developed than in recent years (Fox pers. comm.).
4.0 ACKNOWLEDGEMENTS
Dr. N. Segal assisted with field work.
Assistance by Mike Hislop and staff of the Western Australian Herbarium and other botanists
in identifying plant specimens and access to the Western Australian Herbarium collections,
which was essential for carrying out the project, are greatly appreciated.

APPENDIX A
RARE FLORA WITH DISTRIBUTIONS AND HABITATS
WHICH MAY INCLUDE LOTS 81, 99, 52, 51 AND 50 TOODYAY ROAD
GIDGEGANNUP
Introduction
Table A1 lists 46 taxa (species, subspecies and varieties) of Declared Rare (R) and Priority
(P) Flora recorded in Gidgegannup and nearby. It also lists Endangered (E) and Vulnerable
(V) Threatened Flora recorded in the same area. These 48 are the principal species and other
taxa searched for in the proposed structure plan area comprising Lots 81, 99, 52, 51 and 50
Toodyay Road, Gidgegannup in November 2009. The proposed structure plan area is between
Reen Road (Wilson Street) and Reserve Road on the north side of The Spring Road and
Toodyay Road.
The table also provides information about conservation codes, distributions, locality records,
growth forms, habitats and flowering times. This information is often not comprehensive, but
information about habitat is at least indicative and should help in assessing how likely rare
flora is to occur in the search area.
The Table A1 basic list of taxa was compiled from the results of searches of three Western
Australian Department of Environment and Conservation (DEC) databases and Australian
Government Department of the Environment, Water, Heritage and the Arts Protected Matters
databases. The three DEC databases are (1) Threatened (Declared Rare) Flora (Summary of
Threatened Flora Data) (DEFL), (2) WA Herbarium Specimen (WAHERB Specimen
Database General Enquiry) (WAHERB), and (3) Declared Rare and Priority Flora List
(Access database). The database searches were for Declared Rare, Priority and Threatened
Flora taxa recorded in a rectangle with latitudes and longitudes for the upper left and lower
right corners of 31
0
42’ S and 116
0
06’ E, and 31
0
55’ S and 116
0
20’ E, respectively, and, in
the case of the Access database, the search was for taxa with one or more of the names
Chidlow, Gidgegannup, Mt Helena, Mundaring, Parkerville, Sawyers Valley, Stoneville and
Wooroloo in their distributions.
The DEC databases were searched by an officer in the Species and Communities Branch, and
the DEWHA protected matters search tool was used to generate a report listing matters of
national environmental significance or other matters protected by the EPBC Act that have
been recorded in the same rectangle.
The DEC database search results and the DEWHA protected matters report, and links, also
provided some information about conservation codes, localities and distributions, habitats and
flowering times. Much of the information in the last column of the table - on plant features,
form and habitats - came from FloraBase (2009) and Paczkowska and Chapman (2000).
Additional information in the table was obtained from examination of herbarium specimens
and their labels in the Western Australian Herbarium, consultations with other botanists, and
information in Atkins (2008), Brown et al. (2008), Brown et al. (1998), Hoffman and Brown
(1998), Marchant et al. (1987) and relevant parts of the Flora of Australia and How to Know
Western Australian Wildflowers. These references are listed in the report to which this is
Appendix A.

Conservation Codes Definitions
Department of Conservation and Land Management definitions of the Conservation Codes
(Atkins 2008) in Table A1 are:
R:
Declared Rare Flora – Extant Taxa
Taxa which have been adequately searched for and are deemed to be in the
wild either rare, in danger of extinction, or otherwise in need of special
protection, and have been gazetted as such.
P1:
Priority One – Poorly Known Taxa
Taxa which are known from one or a few (generally <5) populations which are
under threat, . . . Such taxa are under consideration for declaration as ‘rare flora’,
but are in urgent need of further survey.
P2:
Priority Two – Poorly Known Taxa
Taxa which are known from one or a few (generally <5) populations, at least
some of which are not believed to be under immediate threat (i.e. not currently
endangered). Such taxa are under consideration for declaration as ‘rare flora’, but
are in urgent need of further survey.
P3:
Priority Three – Poorly Known Taxa
Taxa which are known from several populations, and the taxa are not believed
to be under immediate threat (i.e. not currently endangered), . . . Such taxa are
under consideration for declaration as ‘rare flora’, but are in need of further survey.
P4:
Priority Four – Rare Taxa
Taxa which are considered to have been adequately surveyed and which,
whilst being rare (in Australia), are not currently threatened by any
identifiable factors. These taxa require monitoring every 5-10 years.
The need for further survey of poorly known taxa is prioritised into the Priority 1, 2 and 3
categories depending on the perceived urgency for determining the conservation status of
those taxa, as indicated by the apparent degree of threat to the taxa based on current
information.
The three Federal Environment Protection and Biodiversity Conservation (EPBC) Act 1999
Threatened Flora categories that are not extinct (and the number of Australian taxa in each
category) are:
C:
Critically Endangered: (89)
E:
Endangered: (523)
V:
Vulnerable: (665)
