1 Introduction This report will form an addendum to the report on a survey carried out in 2012, during which the Project Area (Pinjarra‐Williams Road, SLK 24.4 ‐ 40.0) was surveyed as part of a larger area (NGH Environmental, 20121). The Project Area was surveyed on 18th October 2012 by walking along both sides of the road and searching within the study area (widths as per Table 1). A comprehensive list of native and introduced species was compiled. Taxa that were not able to be identified with certainty in the field were photographed or collected for later identification.

Taxonomy and conservation status of species found during the SLK 24.4‐40.0 section of the 2012 survey were checked against current information from existing species and communities identified in the 2012 survey and considered against up‐to‐date Naturemap and EPBC searches.

While the 2012 survey was mainly concerned with determining whether rare flora occurred within the survey area, a limited amount information was also collected on vegetation type. The main objectives of this review are to re‐assess the 2012 survey to ensure that;  current species and communities (up‐to‐date Naturemap and EPBC searches are attached) are considered against existing data, and  a desktop risk assessment for any newly listed species and communities is carried out.

2.1 Plant Taxa A list of vascular flora species occurring within the Project Area was drawn up using the field note book used during the 2012 NGH Environmental survey. This list, which only includes the taxa from the SLK 20.4 to 40.0 section of the 2012 survey, is presented as Appendix 1. The taxonomy and conservation status of the derived list was checked against the WA Herbarium Census of WA Plants Database (Department of Parks and Wildlife, 2016). The 2012 survey list was also checked against the conservation‐significant flora from recent downloads of data from the EPBC Act Protected Matters search tool and NatureMap (Appendix 2).

Mapping of vegetation complexes by Havel and Mattiske (2000) and notes on vegetation within the Project Area derived from the field notebook used in the 2012 survey were reviewed to determine whether any poorly reserved vegetation complexes or threatened ecological communities (TECs) or priority ecological communities (PECs) occur within the Project Area.

3 Results

3.1 Flora No Declared Rare Flora, Priority flora or flora otherwise of conservation significance were identified within the list of vascular species from the SLK 24.4‐40.00 2012 survey by NGH Environmental.

3.2 Vegetation Types All the vegetation within the Project Area occurs on the Dwellingup (D1) or Yarragil 1 (Yg1) vegetation complexes (Havel and Mattiske, 2000). Both complexes are well reserved with substantially more than the 30% of the pre‐clearing extent of the vegetation type as recommended in the National Objectives Targets for Biodiversity Conservation.

Additionally, there is a higher percentage remaining than the Environmental Protection Authority (2006) target of 15% of pre‐European extent for each ecological community to be protected in a comprehensive, adequate and representative reserve system (Table 2)..

4830 Final 2.0 ii Flora and Vegetation Survey Pinjarra Williams Road (SLK 24.4–65.5) 1 BACKGROUND, SCOPE AND OBJECTIVES

Main Roads WA is proposing to undertake road works, predominately road widening, between SLK 24.4 and 65.5 on the Pinjarra Williams Road (M053), herein referred to as the 'study area'. The study area extends 41.1 km eastwards from Dwellingup to one kilometre west of Marradong.

Study area (Pinjarra Williams Road, SLK 24.4 - 65.5) 010205 Kilometres

Ref: 4830 Author: SP

The surveys included variable widths from the road edge line, on each side of the road, including some sections that did not require any survey (e.g. section 3, SLK 26.8 ‐ 27.6 on the northern side of the road). Refer to Table 1‐1.

Approximately two thirds (the western portion) of the study area is located within or adjacent to the Dwellingup State Forest, which is vested to the Conservation Commission pursuant to the Conservation and Land Management Act 1984. Given that native vegetation is present a spring (2012) Level 1 flora survey was required. The survey was carried out in accordance with EPA Guidance Statement No. 51 ‘Terrestrial Flora and Vegetation Surveys for Environmental Impact Assessment in Western Australia’ (2004). Specifically this included the survey and mapping of the presence of Declared Rare Flora, Threatened Ecological Communities (TEC), Priority Flora, Priority Ecological Communities (PEC) and MNES (including numbers of individuals, population extent and GPS location) within the study area. If they were identified in the study area, then the search was to be expanded at that locality to identify if there were additional populations in the vicinity. In addition the vegetation type within the survey area was to be characterised and its composition compared with TEC/PECs known to occur within a 10 km radius. 2 REGULATORY CONTEXT

Species of flora and fauna are defined as Declared Rare (DRF) or Priority (PF) conservation status where their populations are restricted geographically or threatened by local processes. The Department of Environment and Conservation (DEC) and Department of Sustainability, Environment, Water, Population and Communities (DSEWPC) recognize these threats of extinction and consequently apply regulations towards population and species protection.

Wildlife Conservation Act (1950) DRF species are gazetted under subsection 2 of section 23F of the Wildlife Conservation Act (1950) (Wildlife Cons Act) and therefore it is an offence to “take” or damage rare flora without Ministerial approval. Section 23F of the Wildlife Cons Act defines “to take” as “… to gather, pick, cut, pull, up destroy,

Environmental Protection and Biodiversity Conservation Act (1999) Flora of national or international significance may also be listed as Matters of National Environmental Significance (MNES) under the Environmental Protection and Biodiversity Conservation Act (1999) (EPBC Act). An EPBC Act Protected Matters Report on threatened flora and communities can be generated to confirm the Commonwealth listings for these values (DSEWPC, 2012).

DEC Priority list Priority List Flora are under consideration for declaration as “rare flora”, but are in urgent need of further survey (Priority One to Three) or require monitoring every 5‐10 years (Priority Four). The definitions of Declared Rare and the four Priority ratings under the Wildlife Cons Act are shown below.

R 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 Taxa which are known from one or a few (generally <5) populations which are under threat, either due to small population size, or being on lands under immediate threat. Such taxa are under consideration for declaration as ‘rare flora’, but are in urgent need of further survey P2 Taxa which are known from one or a few (generally <5) populations, at least some of which aret no believed to be under immediate threat. Such taxa are under consideration for declaration as ‘rare flora’, but are in urgent need of further survey. P3 Taxa which are known from several populations, and the taxa are not believed to be under immediate threat (i.e. not currently endangered), either due eto th number of known populations (generally >5), or known populations being large, and either widespread or protected. Such taxa are under consideration for declaration as ‘rare flora’, but are in need of further survey. P4 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.

Ecological communities may also be listed under the Wildlife Cons Act, as MNES or given Priority status.

3 ENVIRONMENTAL SETTING

3.1 BIOREGION, LANDFORMS AND SOILS

The study area is located within the Northern Jarrah Forest sub‐region of the Jarrah Forest bioregion. The climate is classified as warm Mediterranean (Environment Australia, 2000) (SEWPAC, 2012). The Northern Jarrah Forest (JF1) overlies Archaean granite and metamorphic rocks capped by an extensive latertic duricrust that has been dissected by later drainage. It is also interrupted by occasional granite outcrops in the form of isolated hills. The lateritic plateau has an average elevation of 300 m, and is so deeply dissected in the east that it occurs as isolated hills. Rainfall ranges from 1100 mm on its western edge (Darling Scarp)0 to 70 mm in the east and north. Vegetation comprises Jarrah ‐ Marri forest in the west (with Bullich and Blackbutt in the valleys), and grades into Wandoo woodlands in the east with Powder Bark on breakaways. There are extensive but localised sand sheets with Banksia low woodlands. Heath is found on granite rocks and as a common understorey of forests and woodlands in the north and east (Environment Australia, 2000).

4830 Final 2.0 3 Flora and Vegetation Survey Pinjarra Williams Road (SLK 24.4–65.5)

The study area mainly occurs in the Darling Plateau System mapping unit (255Dp), "Lateritic plateau; Duplex sandy gravels, loamy gravels and wet soils; Jarrah‐marri‐wandoo forest and woodland." (DAFWA, 2004) (WA Atlas map viewer, undated). Soils are described as "Duplex sandy gravels, loamy gravels, shallow and deep gravels, deep sands and wet and semi‐wet soils". To a lesser extent the study area also passes through the following:

 Murray Valleys System (255Mv), "Western Darling Range from the Avon Valley to Harvey. Deeply incised valleys with Red loamy earths, shallow duplexes and rock outcrop and Jarrah‐marri‐wandoo forest and woodland with mixed shrubland". Soils are described as "Red loamy earths, shallow duplexes and rock outcrop".  Quindanning System (253Qd), "Deep granitic valleys, in the northern and central Eastern Darling Range, with deep sandy duplex soils, shallow sand, loamy duplex and bare rock. Marri‐wandoo‐york mgum‐ja woodland". Soils are described as "Grey deep sandy duplexes, bare rock, red deep sandy duplexes, red deep loamy duplexes and shallow sands".  Marradong Upland System (253Mu), "Plateau remnants, in the central Eastern Darling Range, with sandy gravel, loamy gravel, grey deep sandy duplex and loamy duplex. Jarrah‐ marri‐wandoo forest and woodland". Soils are described as "Duplex sandy gravels, loamy gravels, grey deep sandy duplexes and loamy duplexes".

3.2 VEGETATION MAPPING

Pre‐European Vegetation at the subject site has been mapped at a broad scale by DAFWA adapted from 1:250,000 Beard mapping (1975, 1981). The study area occurs mostly in the East Darling system, within vegetation association 3: Medium forest; jarrah‐marri. A small section, less than two kilometres long near Ashcroft ,Road is located within association 4: Medium woodland; marri & wandoo. The study area also occurs with 10 different Mattiske and Havel (1998) vegetation complexes, described below. Table 3‐1 Mattiske and Havel (1998) complexes

3.2.1 Threatened and Priority Ecological Communities

No TECs or PECs are known within a 10 km radius of the survey area (DEC, 2012a).

3.2.2 Threatened and Priority flora

Thirteen rare flora taxa are known to occur within approximately five kilometres of the study area (DEC, 2012a). Conditions within the study area may not necessarily be suitable to support them.

4830 Final 2.0 5 Flora and Vegetation Survey Pinjarra Williams Road (SLK 24.4–65.5)

A search was also carried out for the Shires of Murray and Boddington of the EPBC Act protected matters search tool (DSEWPC, 2012). The tool identified species or species habitat known to occur within area for 19 threatened taxa listed under the EPBC Act (1999). This tool is a broad tool that shows if potential habitat may occur locally for MNES, subsequently many species may not actually occur near the site. Of the 19 species only two, Anthocercis gracilis (Vulnerable) and Verticordia fimbrilepis subsp. fimbrilepis (Endangered), have potential to be present at the site due to habitat requirements and the location of the site (for example some are only found on the Swan Coastal Plain).

4 METHODS

4.1 SURVEY METHODS

The alignment was surveyed over three days: 11th, 17th and 18th October 2012, with an additional visit to demarcate Priority flora on 26th October 2012. The survey was carried out by walking along both sides of the road and searching within the study area (widths as per Table 1‐1). A comprehensive list of native and introduced species was compiled. Taxa that were not able to be identified with certainty in the field were photographed or collected for later identification. Rare flora found during the survey were marked in the field using coloured flagging tape. A search was made in the area adjacent to the particular population to ascertain the full extent of the population. Taxonomy and conservation status of species found during the survey was checked against DEC (2012a, 2012b) and DSEWPC (2012).

4.2 SURVEY LIMITATIONS

In accordance with the EPA Guidance Statement No. 51, potential limitations of the assessment have been identified below:

Competency Suitably qualified and licensed individuals carried out the work. Fieldwork and co‐author: Russell Smith, Botanist Desktop assessment and co‐author: Shane Priddle, Manager WA and Certified Environmental Practitioner

Access problems The entire site was accessible, and access was therefore not a limitation.

Timing The field surveys were undertaken in Spring. Although the winter months had been somewhat dryer than average a wetter than average September ensured an extended flowering season. Overall the spring season was good for flora surveys.

Scope A level 1 flora survey was undertaken. Although the entire project area was surveyed, with some areas visited twice, it cannot be guaranteed that all listed flora within the subject site were found. Time available and seasonal effects had negligible impact on the effectiveness of on the survey.

5.1 VEGETATION TYPE AND CONDITION

Vegetation association/complex within the study area are described in Section 3.2. The significance of clearing a particular vegetation association/complex can be determined by comparing current with pre‐ European extents (Government of Western Australia, 2011, and Shepherd, 2007), as shown in the tables below. A detailed assessment of vegetation condition was outside the scope of this survey, however condition within three metres of the road edgeline is generally Degraded, whereas, especially with the State forest areas condition from three metres to the survey extent was Good to Very Good (condition rating as per method of Keighery, 1994).

The EPA supports a threshold level of 30% of the pre‐clearing extent of the vegetation type as recommended in the National Objectives Targets for Biodiversity Conservation; below which species loss appears to accelerate exponentially at an ecosystem level. Below 10% of the original extent then the vegetation type would be considered to be endangered, and clearing which would put the threat level into the class should be avoided (EPA, 2000). The EPA, (2006) also set a target of 15% of pre‐European extent for each ecological community to be protected in a comprehensive, adequate and representative reserve system. Michibin (Mi) and Williams (Wi), highlighted in Table 5‐2 and shown in Appendix B, both contain less than 30% of their PreEuropean extents however then are not below the 10% endangered threshold. They are however well below the 15% reserve target with 6.23% and 0.41% respectively conserved in DEC tenure. Within the study area the Williams complex is located along the lower slopes of the Hotham River valley, and the Michibin complex is located upslope from the Williams complex east of the Hotham River. Some of the vegetation within the study area within the Michibin (Mi) and Williams (Wi) complexes, because it is bounded by farmland, is degraded. However, there are areas of better quality vegetation, particularly where the roadside vegetation is bounded by reserves. Both Beard vegetations generally above the 30% threshold, apart from association 4 at the IBRA scale and within the Shire of Boddington. Vegetation association 4 is also under‐reserved within the Boddington Shire (below the 15% threshhold).

5.2 FLORA

A total of 213 species of vascular flora were identified within the study area, of which 21 were naturalized or introduced taxa. The genus with the largest representation is Fabaceae with 42 taxa, followed by Myrtaceae (18 taxa), Asteraceae (16 taxa) and Proteaceae with 15 taxa. Refer to Appendix A for a full species list of vascular flora.

5.2.1 Weeds

One species, Bridal Creeper (Asparagus asparagoides), is on the list of Declared Plants with the classification of P1 (Introduction of the plant into, or movement of the plant within, an area is prohibited) (DAF, 2011). It is infrequent in the study area, and is mainly found near Dwellingup. This was not mapped as it was outside of the scope of the survey.

5.3 THREATENED OR PRIORITY FLORA

Two Priority flora were found; the P1 taxon Gastrolobium sp. Prostrate Boddington (M. Hislop 2130) (Figure 5‐1) and Goodenia katabudjar which is P3. Gastrolobium sp. Prostrate Boddington (Figure 5‐2) are scattered along 2.4 km of the Pinjarra‐Williams Road west of the Hotham River (approximately between SLK 59.28 and 60.71 and at 61.71), whereas G. katabudjar is restricted to a small area on the southern verge 2.27 km west of the Hotham River (approximately at SLK 59.43). Locations of individual plants or small groups of plants are shown in Appendix C. The populations of both taxa were marked in the field with flagging tape (Figure 5‐3, 5‐4). All individuals of G. sp. Prostrate Boddington are situated between 4 metres and 10 metres from the edge of the bitumen seal, and are mostly growing on the back‐slope or cutting. The largest population of G. katabudjar (c. 200 plants) is situated within an area of road verge woodland about 6 metres from the edge of the road seal on the south side, and covers an area about 10 x 10 metres in extent. There are two small populations of G. katabudjar opposite the large one, on the north side of the road, about 5 metres from the seal containing about 20 plants each.

Figure 5‐4 Flagging showing the location of a population of Gastrolobium sp. Prostrate Boddington (M. Hislop 2130)

There are only four records for Gastrolobium sp. Prostrate Boddington (M. Hislop 2130) in the Western Australian herbarium. The herbarium collections are drawn from a small area between Tullis Bridge east of Boddington to a point 5.1 km west of the Quindanning turnoff along the Pinjarra‐Williams Road. The original collection of this taxon (PERTH 05619033) appears to have come from one of the populations located during the present survey. Goodenia katabudjar is represented by 11 records in the Western Australian herbarium which come from a small area between Wandering and Boddington. It is found in wandoo and wandoo‐jarrah woodland.

5.4 THREATENED OR PRIORITY ECOLOGICAL COMMUNITIES

The vegetation within the study area does not resemble a Threatened or Priority Ecological Community.

6 RECOMMENDATIONS

It is recommended that the populations of Gastrolobium sp. Prostrate Boddington (M. Hislop 2130) and Goodenia katabudjar found during the survey, which are marked in the field with coloured flagging tape,

4830 Final 2.0 10 Flora and Vegetation Survey Pinjarra Williams Road (SLK 24.4–65.5) are protected from damage during the proposed road widening activities. Specific approvals and offsets may be required prior to clearing these specimens or adjacent habitat. Additionally, it is recommended that roadside vegetation belonging to the Williams and Michibin complexes (between SLK 56 and 62) is protected as much as practicable during the proposed operations (see Appendix B). In terms of planning, clearing of these vegetation complexes may require offsets. Clearing should be carried out from east to west (towards Dwellingup) to avoid spreading Bridal Creeper (Asparagus asparagoides). Appropriate hygiene practices should be adopted to avoid the spread of weeds, including consideration of Bridal Creeper in any Environmental Management Plans.

7 CONCLUSIONS

Flora surveys were carried out up to 30m from the road edge line between SLK 24.4 and 65.5 on the Pinjarra Williams Road (M053), over four days in October 2012. A total of 213 species of vascular flora were identified within the study area, of which 21 were naturalized or introduced taxa. The genus with the largest representation is Fabaceae with 42 taxa, followed by Myrtaceae (18 taxa), Asteraceae (16 taxa) and Proteaceae with 15 taxa. Two Priority flora were found; the P1 taxon Gastrolobium sp. Prostrate Boddington (M. Hislop 2130) and P3 Goodenia katabudjar. Gastrolobium sp. Prostrate Boddington occurs approximately between SLK 59.28 and 60.71 and at 61.71, whereas G. katabudjar is restricted to a small area near SLK 59.43. One Declared Weed, Bridal Creeper (Asparagus asparagoides), is infrequent in the study area found mostly near Dwellingup. Of the 10 Mattiske mapped vegetation communities that occur within the study area, Michibin (Mi) and Williams (Wi), both contain less than 30% of their PreEuropean extents. They are also well below the EPA (2006) reserve target of 15% with 6.23% and 0.41% respectively conserved in DEC tenure. Both Beard vegetations are generally above the 30% threshold, apart from association 4 at the IBRA scale and within Boddington Shire. None of the vegetation types occurring in the study area resembles a TEC or PEC.
