EXECUTIVE SUMMARY

The Western Australian State Government Infill Sewerage Program is a major capital works program which will enable properties to connect to a centralised wastewater sewerage system. The Water Corporation propose to commence construction of the Ravenswood/West Murray 2A Infill Sewerage Project. The West Murray 2A Infill Sewerage Project comprises construction of the following infrastructure: Approximately 1.3 km of dual DN110PE pressure sewer pipeline Approximately 1.5 km of DN150 gravity sewer pipeline with associated access chambers A pump station with a wet well to be founded at depth of approximately 9 m below ground level Connections to an existing pressure pipeline and gravity sewer system The ground surface elevations along the pipe line alignments and pumping station generally range between RL 3 m AHD and RL 6 m AHD, with the higher elevation at the pumping station site.Golder Associates commissioned Anders Environmental Consulting to undertake a Level 1 flora and opportunistic fauna survey of the Project area.

The objectives of the survey were to: • develop an inventory of flora and fauna species present within the Project area; • map vegetation communities and their condition occurring within the Project area; • conduct a targeted search for threatened flora species within the Project area; • conduct an opportunistic fauna survey of habitat trees; and • determine any potential impacts the Project may pose on threatened flora, vegetation and fauna.

Flora, vegetation and fauna of the Project area The database searches identified a total of 54 threatened flora species, 17 threatened fauna species and eight threatened ecological communities potentially occurring within Project area.

A total of 34 flora species (including subspecies and variants) were recorded during the survey, including eight weed species, one of which (Lantana camara) is a Weed of National Significance.

Five vegetation communities were identified during the survey, the planted roadside verge has been included however it should be noted that it is not considered to be a naturally occurring vegetation community. Approximately 0.81 hectares of native vegetation is expected to be cleared with a further 0.57 hectares expected clearing within cleared paddocks and 1.28 hectares expected clearing within urban areas. Two Marri (Corymbia calophylla) habitat trees and a termite mound within vegetation community ErNfW are expected to be directly impacted through clearing.

Ravenswood/West Murray 2A Infill Sewerage Project Flora and Fauna

A large number of habitat trees were recorded within the Project area these include: • 16 locations of Marri (Corymbia calophylla); • 1 location of Blackbutt (Eucalyptus patens); and • Flooded gum (Eucalyptus rudis) throughout the Project area.

A total of eight bird species where recorded within the Project area.

Threatened flora, fauna and ecological communities

Two threatened flora species were recorded within the Project area, Grevillea manglesii subsp. ornithopoda (P2) and Eucalyptus rudis subsp. cratyantha (P4). Both species occur along the riverbank as part of the riparian vegetation.

Spotlighting of habitat trees was conducted throughout the Project area, the Common Brushtail Possum (Trichosurus vulpecular), which has a conservation status of least concern under the IUCN Red List was recorded at two locations of Flooded Gum.

Black Cockatoo calls were heard briefly at a distance from the Project area, however they were not sighted to enable identification of species.

Track activity was recorded along the riverbanks which are potentially either that of the native Water Rat (Hydromys chrysogaster), a Priority 4 listed species under the Wildlife Conservation Act (1950) or the introduced Brown Rat (Rattus norvegicus).

A large termite mound was recorded within the planted road verge scrub. Numbats (Myrmecobius fasciatus) feed on termites, however signs of Numbat activity was not present.

No threatened ecological communities were present in the Project area.

Recommendations The following recommendations are made to reduce the potential impact on threatened flora and fauna and ecological values of the Project area: • Clearing of threatened flora species Grevillea manglesii subsp. ornithopoda and Eucalyptus rudis subsp. cratyantha should be avoided. Areas of native vegetation in particular along river banks which require clearing, should be assessed for the presence of threatened flora prior to clearing; • Clearing of habitat trees should be avoided, including Marri (Corymbia calophylla) and Flooded Gum (Eucalyptus rudis);

Ravenswood/West Murray 2A Infill Sewerage Project Flora and Fauna

• Clearing of vegetation along riverbanks should be minimised to reduce the risk of erosion and disturbance to any potential Water Rat populations; • Targeted survey of Black Cockatoo species is required to determine their presence within the Project area; • Further investigation of Common Brushtail Possum populations present within the Project area should be undertaken; • Minimise usage of heavy equipment along riverbanks to prevent erosion; and • Conduct weed hygene practices on plant and equipment.

1.0 Introduction

1.1 Project background

The West Murray 2A Infill Sewerage Project comprises construction of the following infrastructure: Approximately 1.3 km of dual DN110PE pressure sewer pipeline Approximately 1.5 km of DN150 gravity sewer pipeline with associated access chambers A pump station with a wet well to be founded at depth of approximately 9 m below ground level Connections to an existing pressure pipeline and gravity sewer system The ground surface elevations along the pipe line alignments and pumping station generally range between RL 3 m AHD and RL 6 m AHD, with the higher elevation at the pumping station site.

The Project is located within the Shire of Murray approximately 71 kilometers (km) south of Perth (Figure 1).

Although the sewerage infrastructure occurs mainly along cleared roadside easements, clearing of some native vegetation is expected. Golder Associates commissioned Anders Environmental Consulting (AEC) to undertake a Level 1 flora and opportunistic fauna survey of the Project area.

1.2 Scope and objectives

This report documents the results of a Level 1 flora and opportunistic fauna survey (survey) of the Project area. The survey was designed and conducted in accordance with the Western Australian Environmental Protection Authority’s (EPA’s):

• Position Statement No. 3 Terrestrial Biological Surveys as an Element of Biodiversity Protection (EPA, 2002);

• Guidance Statement No. 51 Terrestrial Flora and Vegetation Surveys for Environmental Impact Assessment in Western Australia (EPA, 2004a); and

2.0 Existing environment

2.1 IBRA bioregion

Australia has been classified into 85 bioregions and 403 subregions by the Interim Biogeographic Regionalisation of Australia (IBRA) (Thackway and Cresswall, 1995). The Project area occurs within the Perth IBRA subregion which forms the southern half of the greater Swan Coastal Plain IBRA bioregion, with the Dandaragan Plateau IBRA subregion forming the northern half (Australian Natural Resources Atlas, 2001).

The Swan Coastal Plain is a low lying coastal plain, mainly covered with woodlands. It is dominated by Banksia or Tuart on sandy soils, Casuarina obesa on outwash plains, and paperbark in swampy areas. The outwash plains, once dominated by C. obesa-marri woodlands and Melaleuca shrublands, are extensive only in the south (Mitchell, Williams and Desmond, 2002).

The Perth subregion is composed of colluvial and Aeolian sands, alluvial river flats, coastal limestone. Heath and/or Tuart woodlands on limestone, Banksia and Jarrah-Banksia woodlands on Quaternary marine dunes of various ages, Marri on colluvial and alluvials (Mitchell, Williams and Desmond, 2002).

2.2 Climate

The Swan Coastal Plain experiences a Mediterranean climate with warm, dry summers and mild, wet winters. The closest Bureau of Meteorology (BOM) weather station is located at Mandurah (station number 009572) approximately 10 km north-west of the Project area.

During summer months December to March mean daily maximum temperatures can reach 29.6°C (February). During winter months June to September mean minimum temperatures reach 8.6°C (July/August) (BOM, 2011).

Mandurah receives an average of 882.2 mm of rainfall each year. The majority of rainfall occurs between May and August, with the yearly maxima occurring in June at 189.7 mm (BOM, 2011). Significant variation in rainfall occurs across the region and as such, data provided should only be used as a guide.

2.3 Land use

The Project area is located adjacent to a section of the Murray River which is used for a number of recreational activities including the Ravenswood Road boat ramp, Peel District Canoeing Club and houseboat mooring. The proposed main sewer alignment runs adjacent to existing residential properties and the proposed pumping station is located within an agricultural paddock.

3.0 Method

3.1 Flora survey design

Two levels of flora surveys are defined under the EPA’s Guidance Statement No. 51 Terrestrial Flora and Vegetation Surveys for Environmental Impact Assessment in Western Australia (EPA, 2004). Based on the ecological values of the Project area and nature of the impact, a Level 1 flora survey was determined to be adequate, this required a desktop study, review of maps and aerial imagery and a low intensity field survey.

3.1.1 Desktop study

Prior to commencing the field survey a desktop study was conducted which involved searching Department of Environment and Conservation (DEC) and publically available databases to determine whether any threatened flora, fauna and ecological communities were previously recorded within and surrounding the Project area.

A 10 kilometer (km) search radius around the Project area’s centre point at easting 389900 and northing 6393200 (zone 50H, GDA94) was set and the following databases searched: • DEC Threatened (Declared Rare) Flora database; • Western Australian Herbarium (WAH) Specimen database for priority species opportunistically collected in the area of interest; • DEC Declared Rare and Priority Flora List; • DEC Threatened Ecological Community (TEC) database; • DEC Priority Ecological Community (PEC) database; • Commonwealth EPBC Act, 1999 Protected Matters Database Search Tool; • Department of Sustainability, Environment, Water, Population and Communities Species Profile and Threats Database (SPRAT); • DEC NatureMap database; and • Birds Australia Birdata database.

3.1.2 Vegetation mapping

The flora survey consisted of mapping the vegetation communities and their condition along the proposed sewerage infrastructure alignment at a width of 40 m. The distribution of vegetation communities was planned using aerial photography, with alterations made following on-ground observations and confirmation of vegetation community boundaries. For each vegetation community identified a 10 m x

Ravenswood/West Murray 2A Infill Sewerage Project Flora and Fauna

10m quadrat was established, the information recorded for each vegetation community is provided in Table 1.

Vegetation communities were described using Keighery’s (1994) vegetation classification table (Appendix B). Vegetation condition was defined using the Keighery Scale (Keighery 1994) (Appendix C).

Table 1 Summary of vegetation community data

3.1.3 Targeted flora search

A targeted search of the Project area was conducted for threatened flora species identified in the desktop study. Any potential threatened flora species were collected, their GPS position recorded and population counts conducted.

3.1.4 Specimen identification

A specimen of all flora species recorded was collected and a sample pressed into a field herbarium for verification and identification. Specimens were identified with reference to taxonomic guides and Western Australian Herbarium samples. A species list was compiled using nomenclature from Paczkowska and Chapman (2000).

Ravenswood/West Murray 2A Infill Sewerage Project Flora and Fauna

3.2 Fauna survey design

The level and intensity of the fauna survey required is defined by the EPA’s Guidance Statement No. 56 Terrestrial Fauna Surveys for Environmental Impact Assessment in Western Australia (EPA, 2004b), which is determined by the nature of the impact and the sensitivity of the receiving environment.

The fauna survey consisted of a database search of DEC and publically available databases, on-ground identification of potential fauna habitat trees and opportunistic fauna observations. A full Level 1 fauna survey was not conducted which would have required an additional low intensity sampling of fauna and faunal assemblages.

3.2.1 Fauna habitat identification

A targeted search for habitat trees was conducted, suitable species included Marri (Corymbia calophylla), Blackbutt (Eucalyptus patens) and Flooded Gum (Eucalyptus rudis), locations of individual and groups of habitat trees were recorded. Habitat trees were inspected for nesting hollows, scarring and scratches on trunk and limbs, foraged fruit, droppings and scats, feathers and broken egg shell.

Other signs of fauna presence was also searched for, these included: • habitat logs and stumps; • dense vegetation cover; • burrows, nests and tunnels; • diggings and scratching; • scats; • tracks; • riverbanks; and • rocky areas.

3.2.2 Fauna observations

A number of different observational activities were carried out to maximise the chance of sighting any threatened fauna species present within the Project area.

Spotlighting Spotlighting using handheld torches of all habitat trees identified for the presence of nocturnal species, these include Marri (Corymbia calophylla) and Flooded gum (Eucalyptus rudis). Spotlighting was conducted via foot to minimise noise, with the upper canopy and limbs spotlighted for eyeshine as well as any tree hollows.

Ravenswood/West Murray 2A Infill Sewerage Project Flora and Fauna

Bird observations Bird observations were conducted at four point locations for a fixed time of 15 minutes. Locations were chosen to represent the different habitat types present within the Project area, these were: • Paddock grassland • River bank • Parkland above river bank • Dense scrub / planted verge

Opportunistic bird observations were also conduct as the Project area was traversed. Observations were conducted at two times, early morning and at dusk to enable optimal bird activity to be observed.

Active searches The Project area was searched for signs of scats, tracks, diggings, burrows, tunnelling and other signs of fauna activity. Particular attention was given to areas likely to provide coverage such as dense scrub and understorey vegetation, fallen logs and riverbanks.

3.3 Survey timing and personnel

Long-term average monthly rainfall data (Mandurah Weather Station) shows there is one main rainfall period for the Mandurah region, in winter from May to September (BOM, 2011). Optimal time for conducting the flora and vegetation survey is six to eight weeks following the peak rainfall period, when high level rainfall is expected to have triggered germination growth in many species, producing flowers and fruiting bodies enabling greater accuracy in specimen identification.

The flora and vegetation survey was conducted on Thursday 8th December 2011 approximately nine weeks after the peak rainfall period. The fauna survey was conducted on Monday 19th (morning survey) and Wednesday 21st December 2011 (dusk survey and spotlighting).

The survey was conducted by the following personnel from Golder Associates and AEC: • Field survey: Clint McCullough BSc, MSc (Hons), PhD, MAusIMM Catherine Krens B Sc (Env Sc) (Collecting licence SL009774) • Specimen Identification: Catherine Krens B Sc (Env Sc)

4.0 Results

4.1 Database searches

The database searches identified a total of 54 threatened flora species, 17 threatened fauna species and eight threatened ecological communities potentially occurring within the Project area, including: • 15 Declared Rare Flora (DRF) • Five endangered fauna species • Six vulnerable fauna species • One specially protected fauna species • Two critically endangered ecological communities • Five vulnerable ecological communities

A full list of threatened flora, fauna and ecological communities identified in the desktop study is provided in Appendix D.

4.2 Flora survey

A total of 34 flora species (including subspecies and variants) were recorded during the survey, these included: • 14 families • 24 genera • No DRF species • Two Priority Flora species • Eight weed species

The most dominant family was Myrtaceae (14 taxa) and the most dominant genera was Eucalyptus (5 taxa). A full list of all species recorded during the survey is provided in Appendix E.

4.2.1 Threatened flora species

Ravenswood/West Murray 2A Infill Sewerage Project Flora and Fauna

Grevillea manglesii subsp. ornithopoda Grevillea manglesii subsp. ornithopoda is described as a spreading, virgate shrub, to five metres high and three metres wide. Its flowering period is September to November where it forms white, irregular flowers. It occurs in gravelly soil, or sand, or clay and is found along creek beds (DEC, 2011b).

Its distribution is restricted with only seven populations previously recorded within the Swan Coastal Plain and Jarrah Forest IBRA bioregions (DEC, 2011). It is reasonably common along riverbanks of the Project area, locations within the survey are provided in Appendix F.

Eucalyptus rudis subsp. cratyantha Eucalyptus rudis subsp. cratyantha is described as a tree, five to 20 metres high, with rough, box-type bark. Its flowering period is July to September where if forms white flowers. It occurs in loamy soils and is found on flats and hillsides. It was recorded at only one location within the Project area, its location within the Project area is provided in Appendix F.

4.2.2 Weeds

Eight weed species were recorded within the Project area, these were: • Ehrharta calycina (Perennial Veldt Grass) • Gladiolus undulates (Wild Gladiolus) • Hordeum marinum • Lagurus ovatus (Hare's Tail Grass) • Lantana camara (Common Lantana) • Tropaeolum majus (Garden Nasturtium) • Watsonia meriana var. bulbillifera • Zantedeschia aethiopica (Arum lily)

Weed cover was high throughout the Project area up to 90% in some areas, contributing factors include the close proximity to urban and agricultural areas, high level of recreational activity (jetty’s, canoeing, house boats) and small pockets of remaining intact remnant vegetation readily encroached by weeds.

The grassy pasture weeds Ehrharta calycina, Hordeum marinum and Lagurus ovatus formed the main species composition of the paddock, extensive spread of these weeds throughout the Project area has occurred in particular at remnant vegetation edges.

Ravenswood/West Murray 2A Infill Sewerage Project Flora and Fauna

Gladiolus undulates, Watsonia meriana var. bulbillifera and Zantedeschia aethiopica are common wetland weeds, they were all recorded along the riverbanks adjacent to jettys and carparks. Lantana camara and Tropaeolum majus were also recorded along riverbanks and have most likely entered as garden escapees.

One Weed of National Significance (WoNS) was recorded, Lantana camara (Lantana). It was identified as a WoNS because of its invasiveness, potential to spread and impacts on the environment and primary industry. Lantana was recorded at one location along the riverbank. Locations of weeds within the project area is provided in Appendix F.

4.3 Vegetation communities

No threatened ecological communities occur within the Project area.

MpW - Melaleuca preissiana Low Open Woodland

Melaleuca preissiana low open woodland over Ehrharta calycina and Hordeum marinum closed tussock grassland.

A paddock dominated by pasture grass species which is actively used for grazing cattle. The proposed pump station will be located within this community. Vegetation condition is completely degraded as it can be described as ‘parkland cleared’ with the flora comprising weed or crop species with isolated native trees or shrubs (Keighery, 1994).

ErNfW - Eucalyptus rudis / Nuytsia floribunda Woodland

Eucalyptus rudis, E. patens and Nuytsia floribunda woodland over Ehrharta calycina and Poaceae sp. tussock grassland.

This vegetation community occurred above riverbanks, it is dominated by a mixture of large trees (Eucalyptus rudis, E. patens and E. camaldulensis subsp. obtusa) over grasses. One section adjacent to the Ravenswood Road boat ramp carpark appears to be planted with mixed species (Callistemon sp., Dianella sp.), these were not included in the species inventory.

Vegetation condition was mainly good, however some areas were classified as degraded due to heavy weed infestation.

ErOFMrLW - Eucalyptus rudis Open Forest over Melaleuca rhaphiophylla Low Woodland

Eucalyptus rudis and Corymbia calophylla open forest over Melaleuca rhaphiophylla and Casuarina obese low woodland over Astartea leptophylla tall open shrubland. This vegetation community occurs along riverbanks as riparian vegetation.

Vegetation condition was mainly good due to a high percentage of weed cover present (30-40%) especially close to the Ravenswood Road jetty and carpark, areas furtherest from the jetty area were in very good condition.

ErWJsS - Eucalyptus rudis Woodland over Jacksonia sternbergiana Shrubland

Eucalyptus rudis and Corymbia calophylla woodland over Jacksonia sternbergiana and Acacia pulchella var. pulchella shrubland. This vegetation community was situated along riverbanks as riparian vegetation.

Overstorey species composition was the same as vegetation community ErOFMrLW, however the understorey differed with Jacksonia sternbergiana and Acacia pulchella var. pulchella being the dominant species. Vegetation condition was good to very good due to perennial veldt grass Ehrharta calycina common throughout.

4.3.1 Vegetation clearing

Approximately 0.81 hectares of native vegetation is expected to be cleared with a further 0.57 hectares expected clearing within cleared paddocks and 1.28 hectares expected clearing within urban areas. The amount of clearing within each vegetation community is provided in table 3 and a map of the vegetation communities to be cleared is provided in Appendix J.

Impacts on vegetation communities and fauna habitats have been minimised with the majority of clearing to occur in urban areas and cleared paddocks (vegetation community MpW). In addition all locations of threatened flora species and fauna habitats of Common Brushtail Possum (Trichosurus vulpecular) and potential Water Rat (Hydromys chrysogaster) / Brown Rat (Rattus norvegicus) will be avoided. However some impacts through clearing are expected to occur within vegetation community ErNfW: • Two Marri (Corymbia calophylla) habitat trees directly impacted at location 50H 390117E 6392904N • Termite mound directly impacted at location 50H 389909E 6393153N.

4.4 Fauna survey

Habitat trees A large number of habitat trees were recorded within the Project area these include: • 16 locations of of Marri (Corymbia calophylla); • 1 location of Blackbutt (Eucalyptus patens); and • Flooded gum (Eucalyptus rudis) common throughout the Project area

The location of habitat trees is provided in Appendix H and I.

No tree hollows suitable for nesting, limb scars and scratching, foraged fruit or feathers were recorded.

Common Brushtail Possum (Trichosurus vulpecular) Spotlighting of habitat trees was conducted throughout the Project area, the Common Brushtail Possum (Trichosurus vulpecular) was recorded at two locations of Flooded Gum. The location of habitat trees is provided in Appendix I.

The Common Brushtail Possum has a conservation status under the IUCN Red List of least concern, it is not listed under the EPBC Act (1999) or Wildlife Conservation Act (1950).

The two locations occurred within 200 metres of each other, a large number of potential habitat trees are present throughout the Project area, further investigation may reveal additional Possum locations.

Plate 7: Close up image of two Common Brushtail Possums

Baudin, Carnaby and Red-tailed Black Cockatoo (Calyptorhynchus sp.) Black Cockatoo calls were heard briefly at a distance from the Project area, however they were not sighted and were moving away from the Project area. It was difficult to determine which Cockatoo species without a visual sighting, Baudin and Carnaby cockatoos calls are very similar, identification is most easily determined by the beak size.

The conservation status of Baudin, Carnaby and Red-tailed Black Cockatoo within the IUCN Red List, EPBC Act (1999) and Wildlife Conservation Act (1950) is provided in Table 3.

Marri provide habitat for all three black Cockatoo species, however Marri is in low numbers and scattered throughout the Project area which may not provide viable habitat. Further survey work is required to determine whether any Black Cockatoo species occur within the Project area.

Water Rat (Hydromys chrysogaster) / Brown Rat (Rattus norvegicus) A large amount of track activity was recorded along the riverbank adjacent to the Peel District Canoe Club carpark. The tracks are potentially either that of the native Water Rat (Hydromys chrysogaster) or the introduced Brown Rat (Rattus norvegicus), track marks are very similar for both species with four distinctive claws, three pointing forward and one to the side (Triggs, 2004). The riverbank was searched for tunnels however no evidence was found. The location of the tracks is provided on Appendix I.

The native Water Rat has a conservation status under the IUCN Red List of least concern and Priority 4 under the Wildlife Conservation Act (1950).

Plate 8: Close up image of potential Water Rat tracks

Plate 9: Potential Water Rat tracks Termite mound (Nasutitermes exitiosus) A large termite mound was recorded within the planted road verge scrub. Numbats (Myrmecobius fasciatus) feed on termites and have previously been recorded in the area. The termite mound was searched for signs of Numbat activity including scats and diggings however no evidence was found of Numbat presence or any disturbance to the termite mound.

Plate 10: Termite mound

Bird observations Bird observations were conducted for 15 minutes at four locations to represent the different habitat types within the Project area. These include: • Paddock grassland (Adam Road) • River bank (Ravenswood Road jetty and boat ramp) • Parkland above river bank (Peel District Canoe Club carpark) • Dense scrub / planted verge (Pinjarra Road plant verge scrub)

Bird observations were also made opportunistically as the Project area was traversed. A total of eight bird species were recorded, these are listed in Appendix E.

5.0 Conclusions

5.1 Potential impacts

The proposed infill sewerage project is located predominantly on existing road easements, however some disturbance to native vegetation through clearing is expected. The Project will potentially impact on the following ecological values:

Threatened flora Vegetation clearing should be avoided were possible to reduce soil erosion, the spread of weeds and loss of native vegetation. Clearing should in particularly be avoided for the two threatened flora species present within the Project area, Grevillea manglesii subsp. ornithopoda and Eucalyptus rudis subsp. cratyantha. Impacts will be greatest along riverbanks where populations have been recorded and clearing of these areas should be avoided. Populations of these two species are restricted and reduction in individual species through clearing may further restrict their population.

Threatened fauna Presence of threatened Black Cockatoo species within the Project area is unknown, although calls were heard confirmation of species and their presence within the Project area was not determined. Further survey work is required to determine their presence. Clearing of habitat trees potentially utilised by Cockatoos within the Project area should be avoided.

Populations of Common Brushtail Possums in Flooded Gum were recorded within the Project area. Flood Gum occurs extensively throughout the project area along riverbanks, the extent of Possum populations is not fully known and further investigation is required. Clearing of Flooded Gum should be avoided.

Ravenswood/West Murray 2A Infill Sewerage Project Flora and Fauna

Presence of potential Water Rat populations was recorded along riverbanks near the Peel District Canoeing Club carpark. Clearing or riverbank understorey vegetation in particular near potential Water Rat tracks should be avoided as well as use of heavy machinery along riverbanks, to reduce the potential of erosion to occur.

Vegetation communities and fauna habitats The two Marri (Corymbia calophylla) habitat trees and termite mound within vegetation community ErNfW expected to be directly impacted should be avoided if possible or disturbance in particular to the termite mound should be kept to a minimum.

Weeds The Project area has a high percentage of weed cover, further spread of weeds via machinery and exposed bear ground from clearing along the sewer infrastructure alignment should be minimised through weed hygene of plant and equipment.

5.2 Recommendations

The following recommendations are made to reduce the potential impact on threatened flora and fauna and ecological values of the Project area:

• Clearing of threatened flora species Grevillea manglesii subsp. ornithopoda and Eucalyptus rudis subsp. cratyantha should be avoided. Areas of native vegetation in particular along river banks which require clearing should be assessed for the presence of threatened flora prior to clearing; • Clearing of habitat trees should be avoided, including Marri (Corymbia calophylla) and Flooded Gum (Eucalyptus rudis); • Clearing of vegetation along riverbanks should be minimised to reduce the risk of erosion and disturbance to any potential Water Rat populations; • Targeted survey of Black Cockatoo species is required to determine their presence within the Project area; • Further investigation of Common Brushtail Possum populations present within the Project area should be undertaken; • Minimise usage of heavy equipment along riverbanks to prevent erosion; and • Conduct weed hygene practices on plant and equipment.

Definitions of threatened fauna species (DEWHA, 1999)

Conservation code Category description

A taxon is Endangered when the best available evidence indicates that it is Endangered considered to be facing a very high risk of extinction in the wild.

A taxon is Vulnerable when the best available evidence indicates that it is Vulnerable considered to be facing a high risk of extinction in the wild.

Taxa which are known from few specimens or sight records from one or a few Priority 1 localities on lands not managed for conservation, e.g. agricultural or pastoral lands, urban areas, active mineral leases. The taxon needs urgent survey and evaluation of conservation status before consideration can be given to declaration as threatened fauna. Taxa which are known from few specimens or sight records from one or a few localities on lands not under immediate threat of habitat destruction or Priority 2 degradation, e.g. national parks, conservation parks, nature reserves, State forest, vacant Crown land, water reserves, etc. The taxon needs urgent survey and evaluation of conservation status before consideration can be given to declaration as threatened fauna. Taxa which are known from few specimens or sight records from several Priority 3 localities, some of which are on lands not under immediate threat of habitat destruction or degradation. The taxon needs urgent survey and evaluation of conservation status before consideration can be given to declaration as threatened fauna. Taxa which are considered to have been adequately surveyed, or for which Priority 4 sufficient knowledge is available, and which are considered not currently threatened or in need of special protection, but could be if present circumstances change. These taxa are usually represented on conservation lands.

Priority 5 Taxa which are not considered threatened but are subject to a specific conservation program, the cessation of which would result in the species becoming threatened within five years.

Appendix C Vegetation condition scale

Vegetation Condition Scale (Keighery 1994)

Code Description

Pristine Pristine or nearly so. No obvious signs of disturbance.

Vegetation structure intact, disturbance affecting individual species and Excellent weeds are non-aggressive species.

Vegetation structure altered obvious signs of disturbance. For example, disturbance to vegetation structure caused by repeated fires, the Very Good presence of some more aggressive weeds, dieback, logging and grazing.

Vegetation structure significantly altered by very obvious signs of multiple disturbances. Retains basic vegetation structure or ability to Good regenerate it. For example, disturbance to vegetation structure caused by very frequent fires, the presence of some very aggressive weeds at high density, partial clearing, dieback and grazing.

Basic vegetation structure severely impacted by disturbance. Scope for regeneration but not to a state approaching good condition without Degraded intensive management. For example, disturbance to vegetation structure caused by very frequent fires, the presence of very aggressive weeds, partial clearing, dieback and grazing.

The structure of the vegetation is no longer intact and the area is completely or almost completely without native species. These areas Completely Degraded are often described as ‘parkland cleared’ with the flora comprising weed or crop species with isolated native trees or shrubs.
