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 2 (Eucalyptus) calophylla) forest (e 3Mc) 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.

2 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.

4 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 310 42’ S and 1160 06’ E, and 310 55’ S and 1160 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)
