61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) i Preliminary Environmental Impact Assessment 1. Introduction

1.1 Background Main Roads Western Australia (MRWA) is currently planning to commence road formation and drainage improvements along approximately 37 km of the Gibb River Road (SLK 286.5 – 324.1) (the Project). Figure 1 identifies the location of the proposed Project. The proposed road formation and drainage improvements require the sourcing of gravel and other fill materials. Eight material areas have been proposed as suitable areas from which to extract road•building materials for the proposed Project. These areas will be investigated to locate naturally occurring gravel material suitable for the Project works. The Gibb River Road is a predominantly gravel road that was originally built to provide road access to remote Kimberley stations. It runs approximately 650 km between Derby and intersects with the Great Northern Highway between Wyndham and Kununurra. The proposed work will:

» improve the road condition,

» provide increased serviceability,

» reduce maintenance and freight costs; and

» improve the level of serviceability to the local community.

1.2 Purpose of this Report MRWA requires a Preliminary Environmental Impact Assessment (PEIA) for the proposed Project. This report details the findings of the PEIA undertaken for the Study Area, and

» describes the significant aspects of the existing environment;

» details the primary environmental and social impacts of the proposed works;

» identifies any matters likely to warrant referral to the Environmental Protection Authority and/or the Commonwealth Department of the Environment, Water, Heritage and the Arts; and

» provides recommendations for additional investigations that may be required to clarify the expected environmental impacts of the proposed works.

Acid Sulphate Soils Ö The probability of Acid Sulphate Soils occurring within the Study Area is extremely low (CSRIO, 2006).

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 6 Preliminary Environmental Impact Assessment 4. Existing Environment

4.1 Climate The Kimberley Region has a tropical monsoon climate dominated by two seasons, referred to as the ‘wet’ and the ‘dry’, separated by short transitional periods. Hot, humid and high rainfall conditions characterise a wet season, extending over the months from November to April. The region receives around 90% of its rainfall during this season mainly from thunderstorms, monsoonal rain and occasionally, tropical cyclones. The dry season occurs from May to October as high pressure systems dominate the weather patterns with south easterly air flows from the interior bringing sunny days and cooler nights (Kimberley Development Commission, 2009). Extreme weather events are a significant component of the Kimberley climate. Tropical cyclones and tropical storms can bring heavy and sustained rainfall, particularly in the months leading up to and during the wet season. It is common for a large proportion of the Regions’ rainfall to be recorded in one single event, leading to extensive flooding of rivers, creeks and roadways. The closest Bureau of Meteorology weather station to the Study Area is at Mount Elizabeth, located approximately 50 km to the north east. Recorded climatic data for this weather station is presented in Graph 1 and summarised as follows:

» Mean Daily Maximum Temperature: 36.4°C (November) to 28.0°C (June)

» Mean Daily Minimum Temperature: 22.2°C (December) to 7.8°C (July)

» Mean Annual Rainfall: 974.8 mm

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 7 Preliminary Environmental Impact Assessment 4.2 Landuse The Study Area crosses the following two Shires:

» Shire of Wyndham•East Kimberley; and

» Shire of Derby•West Kimberley. Much of the Kimberley Region is occupied by pastoral lease land used for extensive cattle grazing. The remainder of the region is occupied either by Aboriginal reserves, mining leases, national parks, conservation reserves, nature reserves, private nature reserves, military reserves and vacant crown land. The Study Area traverses either unallocated crown land or pastoral lease holding. The pastoral lease is indicated as follows:

» Pastoral Lease Holding: Mt Barnett; used primarily for the roadhouse at Mt Barnett.

» Pastoral Lease Holding: Gibb River.

4.3 Topography and Soils The Study Area is located in the Southern Kimberley Plateau Zone (Tille, 2006). This zone is characterised by hills, ranges and plateaux (with undulating plains and lateritic uplands) on Kimberley Basin sedimentary and volcanic rocks. Stony soils with some red/brown non•cracking clays, shallow gravels, red loamy earths, yellow deep sands and red shallow sands are present. The Geological Survey of Western Australia (1969, 1992) describes the soils of the Study Area as comprising:

» Soil, sandy soil, alluvium;

» White, medium to coarse•grained quartz sandstone;

» Tholeiitic basalt; minor agglomerate and feldspathic sandstone;

» Black soil;

» Alluvium near the Barnett River; and

» White to pale brown quartz sandstone.

4.4 Hydrology

4.4.1 Surface Waters The Kimberley Region contains some very large fresh surface water resources. Waterways and wetland areas within the Kimberley Region are ephemeral, and typically flow or fill during seasonal rainfall events. The Gibb River Road crosses many natural waterways, the majority of which are ephemeral. Barnett River and Manning Creek transverse Gibb River Road within the Study Area (Figure 1). No wetlands are located within or near to the Study Area.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 8 Preliminary Environmental Impact Assessment 4.4.2 Drainage Monsoonal rainfall causes extensive sheet flow flooding over the flat landscape and often creates ephemeral, dendritic drainage lines and rivers with extensive floodplain areas. The often sandy nature of these drainage lines makes them susceptible to erosion from channelised runoff and grazing livestock. Surface water drains directly off road surfaces. A high frequency and high intensity rainfall event during the wet season often causes flooding of the road surface in floodway areas and at river crossings.

4.4.3 Groundwater Management Areas A search of the Department of Water (DoW) Geographic Data Atlas indicated that the Study Area is not located within any Gazetted Public Drinking Water Source Areas, but is within the Canning•Kimberley Groundwater Area. The Canning•Kimberley Groundwater Area covers the entire Kimberley sub•region. This area was proclaimed in 1997 under the Rights in Water and Irrigation Act (1914) to ensure groundwater is abstracted sustainably. The northern section of the Study Area is also located within the Fitzroy River and Tributaries Surface Water Management Area, proclaimed under the Rights in Water and Irrigation Act (1914). The Act gives the DoW the power to manage ground and surface areas and use of land that may impact upon these water sources. Permits are required to allow abstraction or interference with the bed or banks of a watercourse to which there is access by a public road or reserve, or to build or alter a dam on a proclaimed or prescribed watercourse or wetland. MRWA will need relevant approvals where dewatering, abstraction of groundwater or modification of stream banks, or the taking of surface water is required for roadworks and material extraction. The DoW will need to be consulted and the following approvals will be required.

» For dewatering – ‘Application for a 5C Licence to take Groundwater’ (Form A); and

» For modifying beds and banks – ‘Application for a 5C licence to take surface water / Application for a 11/17/21 A permit to modify bed and banks / Application to amend a 11/17/21A permit to modify bed and banks’ (Form C).

4.5 Reserves and Conservation Areas No reserves or conservation areas are located within or adjacent to the Study Area. The closest conservation area to the Study Area is King Leopold Ranges Conservation Park, which is located approximately 70 km to the west (Figure 1).

4.5.1 Environmentally Sensitive Areas Environmentally Sensitive Areas (ESAs) are subject to definition under Section 51B of the Environmental Protection Act (1986). The Department of Environment and Conservation (2009b) does not identify any Environmentally Sensitive Area (ESA) within or adjacent to the Study Area.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 9 Preliminary Environmental Impact Assessment 4.6 Vegetation

4.6.1 Vegetation Types The vegetation of the Study Area is identified by Beard (1979) as likely to contain the following vegetation associations:

» Vegetation Association 75: Grasslands, curly spinifex, low tree savanna woodland; gnaingar (Eucalyptus phoenicea) and [Corymbia] ferruginea over [Triodia bitextura];

» Vegetation Association 739: Grasslands, high grass savanna woodland; grey box Eucalyptus tectifica and cabbage gum over white grass (Sehima nervosum); and

» Vegetation Association 774: Grasslands, tall bunch grass savanna sparse low tree; [Vachellia] suberosa over Mitchell grass on black soil.

4.6.2 Vegetation in a Regional Context A vegetation type is considered under represented if there is less than 30% of its original distribution remaining. From a purely biodiversity perspective, and not taking into account any other land degradation issues, there are several key criteria now being applied to vegetation in States where clearing is still occurring (Environmental Protection Authority, 2000), namely:

» The “threshold level” below which species loss appears to accelerate exponentially at an ecosystem level is regarded as being at 30% of the pre•European / pre•1750 extent for the vegetation type;

» A level of 10% of the original extent is regarded as being a level representingEndangered; and

» Clearing which would put the threat level into the class below should be avoided. Such status can be delineated into five classes (Table 3).

Table 3 Vegetation Extent and Status

Class Classification

Presumed Extinct Probably no longer present in the bioregion

Endangered* < 10% of pre•European extent remains

Vulnerable* 10•30% of pre•European extent exists

Depleted* < 30% and up to 50% of pre•European extent exists

Least Concern < 50% pre•European extent exists and subject to little or no degradation over a majority of this area. Note: * or a combination of depletion, loss of quality, current threats and rarity gives a comparable status The extent of the vegetation in the Study Area is considered to be of Least Concern, with 100% of the pre•European extents considered to be remaining in the Central Kimberley Interim Biogeographic Regionalisation for Australia (IBRA) region (Shepherd, 2005) (Table 4).

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 11 Preliminary Environmental Impact Assessment 4.6.3 Threatened Ecological Communities No TECs protected under the Environment Protection and Biodiversity Conservation Act 1999 are known to be present within the Study Area (Department of Environment, Water, Heritage and the Arts, 2009a). A search of the DEC’s Threatened Ecological Communities (TEC) database was undertaken for the Study Area. No TEC’s are known to be located within the Study Area. However, there are occurrences of the following ecological community within approximately 5 km of the search area:

» The ‘Priority 1’ ecological community – ‘Organic mound spring sedgeland community of the North Kimberley Bioregion’.

4.7 Flora

4.7.1 Threatened Flora Flora species considered to be threatened are listed under the Wildlife Conservation Act (1950) and the Environment Protection and Biodiversity Conservation Act 1999. The DEC also keeps a list of Priority Flora species that are not listed under legislation but for which the DEC feels there is cause for concern, or for which not enough information is known (Table 9 and Table 10, Appendix A). An Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) Protected Matters Search was undertaken for the Study Area. No flora species of conservation significance are known to occur, or considered to have habitat, in the search area. A search was also undertaken through the DECs threatened flora databases (ref #: 37•0309) and NatureMap (Department of Environment and Conservation, 2009c) for species of Declared Rare and Priority Flora located within the vicinity of the Study Area. Descriptions of those species recorded from these searches are presented in Table 11, Appendix A. One Declared Rare Flora (DRF) and 29 Priority Flora species were identified from the search area. The DECs threatened flora database search results and the Protected Matters Search results are presented in Appendix C. The recorded locations of these species are presented in Figure 2. None of these identified species are located within the boundaries of the Study Area.

4.7.2 Previous Surveys A vegetation and flora survey undertaken by GHD (2005) included a section along the Gibb River Road from SLK 280 to SLK 287. No DRF or Priority species were located in the search area during the vegetation and flora survey.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 12 Preliminary Environmental Impact Assessment 4.7.3 Weeds The margins of roads are often excellent habitat for weed species as they respond well to disturbance and quickly colonise exposed areas. Runoff from the exposed road surface often pools in depressions adjacent to the road, aiding the growth of weeds. Roads can also act as transport corridors for weeds, with vegetative parts and seeds of weeds “hitching rides” on vehicles. Other pests also can spread into an area in the same way. The Draft Kimberley Natural Resource Management Plan (Rangelands NRM Coordinating Group, 2004) identified a number of weeds of significance in the Kimberley Region (Table 5). The Department of Agriculture and Food (2009) have recorded 84 Declared Plants as occurring within the Shire of Derby•West Kimberley and Wyndham East Kimberley.

Table 5 Weeds Of National Significance (WONS), Declared Plants and Regionally significant weed species that may occur in the Study Area

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 13 Preliminary Environmental Impact Assessment 4.8 Fauna

4.8.1 Fauna Habitat The dominant habitat types located in the Study Area are likely to be:

» High grass savanna woodland; and

» Riparian vegetation along rivers / creeklines. These vegetation types would provide shelter for a range of fauna species. Barnett River crosses the Gibb River Road within the Study Area. Vegetation along this corridor would be expected to support a variety of bird and amphibian species during the wet season. The dominant vegetation types located within the Study Area, are common and widespread, with an estimated 100% remaining (refer to Table 3 ). The nature of much of the clearing (being linear), adjacent to 100% vegetation extents, is unlikely to be necessary for the maintenance of significant habitat for indigenous fauna, including several threatened and Priority fauna species known to exist in the general vicinity. It is considered that the proposed works will not significantly impact the resident individual species and species distributions levels.

4.8.2 Threatened Fauna The conservation of fauna species and their significance status is currently assessed under both State and Commonwealth Acts. The acts include the Western Australian Wildlife Conservation Act 1950; Wildlife Conservation (Specially Protected Fauna) Notice 2008, and the Environment Protection and Biodiversity Conservation Act 1999. The DEC also produces a supplementary list of Priority Fauna, being species that are not considered “threatened” under the Western Australian Wildlife Conservation Act 1950 but for which the Department feels there is a cause for concern. These species have no special protection, but their presence would normally be considered to determine any potential impacts on these species. The classification schedules are provided in Table 12 and Table 13, Appendix B. The DEC’s Threatened and Priority Fauna Database and the Environmental Protection and Biodiversity Conservation Act 1999 (EPBC Act) Protected Matters Database (Department of the Environment, Water, Heritage and the Arts, 2009a) was conducted for the Study Area. The threatened fauna species listed from these searches and a comment on their likelihood of occurrence in the Study Area are presented in Table 14, Appendix B. The DEC’s Threatened and Priority Fauna Database search results and the Protected Matters Search results are presented in Appendix C.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 14 Preliminary Environmental Impact Assessment It should be noted that some species that appear in the EPBC Act Protected Matters Search Tool are often not likely to occur within the specified area, as the search provides an approximate guidance to matters of national significance that require further investigation. The records from the DEC searches of threatened fauna provide more accurate information for the general area; however some records of sightings or trappings can be dated and often misrepresent the current range of threatened species.

Migratory Species The EPBC Act also protects migratory species that are listed under the following International Agreements:

» Appendices to the Bonn Convention (Convention on the Conservation of Migratory Species of Wild Animals) for which Australia is a range state under the Convention;

» The Agreement between the Government of Australia and the Government of the Peoples Republic of China for the Protection of Migratory Birds and their Environment (CAMBA);

» The Agreement between the Government of Japan and the Government of Australia for the Protection of Migratory Birds and Birds in Danger of Extinction and their Environment (JAMBA); and

» Listed migratory species also include species identified in other international agreements approved by the Commonwealth Environment Minister. The Act also protects marine species on Commonwealth lands and waters. The Protected Matters Search Tool lists 14 Migratory species, protected under the EPBC Act, which may occur in the Study Area. Most migratory species, if occurring in the area, will be present as foraging species during the wet season. Many of these migratory species are considered common in Western Australia and do not have special protection under the Western Australian Wildlife Conservation Act 1950. The likelihood of these species being impacted by the proposed Project is considered minimal. The Protected Matters Search results are presented in Appendix C.

4.8.3 Introduced Species The following introduced species are known to occur in the Central Kimberley IBRA region:

» Canis lupus (Dingo);

» Felis catus (Cat);

» Equus caballus (Brumby, Horse);

» Equus asinus (Donkey); and

» Bos indicus (European Cattle).

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 15 Preliminary Environmental Impact Assessment 4.9 European Heritage A search of the following databases was undertaken to determine if any European Heritage sites will be impacted by the proposed works:

» the Australian Heritage Places Inventory;

» the Heritage Council of Western Australia – Places Database; and

» the Australian Heritage Database. One heritage place from the Heritage Council of Western Australia – Places Database was identified, namely:

» Mount Barnett Station Homestead: Place No: 09776. This heritage place is located on the LHS of the Gibb River Road, between Galvans Gorge and Barnett River Gorge (Figure 2). This heritage place is not located within the Study Area and is unlikely to be impacted by the proposed Project works.

4.10 Aboriginal Heritage The Aboriginal Site Register is held under Section 38 of theAboriginal Heritage Act (1972). It protects places and objects customarily used by, or traditional to, the original inhabitants of Australia. Where an activity disturbs an Aboriginal site or object an application for permission to disturb will need to be submitted under Section 18 of the Aboriginal Heritage Act 1972. Where a site of previously unknown Aboriginal Heritage is to be disturbed, it is advised that a detailed anthropological and archaeological heritage survey is undertaken to find if there are any sites or objects of significance in that area, as it is an offence to disturb all Aboriginal Heritage sites, even those not contained on the Aboriginal Heritage Site Register. In the event that Aboriginal archaeological or ethnographic sites are discovered during construction, there will be a need to meet the requirements of the Aboriginal Heritage Act (1972). A search of the Department of Indigenous Affairs (DIA) Aboriginal Heritage Inquiry System identified a total of 18 registered Aboriginal Heritage sites within the vicinity of the Study Area. The search results from the Aboriginal Heritage Inquiry System are provided in Appendix D. Of the 18 identified Aboriginal Heritage Sites, four are within the vicinity of the Study Area (Table 6). The approximate location of the registered sites has been presented in Figure 2. It should be noted that a search under the DIA database is not a valid full assessment under the Aboriginal Heritage Act WA 1972. This would require consultation with Aboriginal people with knowledge of the area (usually, but not necessarily Native Title Claimants), and an archaeological survey.

4.11 Noise and Vibration Noise and vibration will be generated during the construction phase. While disruption to traffic flow will occur during construction, tourist traffic numbers are relatively low, and occupied homesteads and campsites are a significant distance from the section where work is to be carried out. Therefore, noise and vibration are not likely to be significant aspects of the Project, due to the lack of sensitive receptors in the area.

4.12 Dust Dust will be generated during the roadworks. Dust is already an anticipated feature of travel along the route by virtue of the usual vehicle and stock and freight transport traffic. In addition, tourist traffic numbers are relatively low, and occupied homesteads and campsites are some distance from the section where work is to be carried out.

4.13 Visual Amenity Minimal impacts on visual amenity for road users will occur due to the clearing of remnant vegetation within the road reserve and Material Investigation Areas. Due to the relatively minor nature of the works, the fact that a road already exists in the locality and low numbers of surrounding residents, these impacts are expected to be minor and temporary. Rehabilitation of material areas will reduce the visual amenity of the Study Area after Project construction works.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 17 Preliminary Environmental Impact Assessment 4.14 Public safety and Risk The remoteness of the Gibb River Road minimises risks to public safety. Public safety and traffic safety during construction will be managed in accordance with Standard Contract Specifications. The works do not interact with or traverse any identified gas pipelines or areas likely to contain unexploded ordinance (UXO) (Arnold, A, pers. comm., 2009).

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 18 Preliminary Environmental Impact Assessment 5. Vegetation Clearing

Any clearing of native vegetation requires a permit under Part V of the Environmental Protection Act (1986) except where exemptions apply under Schedule 6 of the Act or are prescribed in the Environmental Protection (Clearing of Native Vegetation) Regulations 2004. These exemptions do not apply in Environmentally Sensitive Areas (ESAs). Main Roads have been granted a Purpose Clearing Permit (CPS 818/4) under the provisions of the Environmental Protection (Clearing of Native Vegetation) Regulations 2004.This permit provides for Main Roads to conduct such clearing associated with roadworks projects where that clearing is:

» The clearing is not at variance with the “Ten Clearing Principles”; and

» Not within an Environmentally Sensitive Area.

5.1 DEC’s “Ten Clearing Principles” The clearing required for the proposed Project has been assessed against the “Ten Clearing Principles” (Appendix E). Based on the findings of the desktop survey, the clearing is considered to be potentially at variance with Clearing Principle ‘c’ of the ‘Ten Clearing Principles’, being;The area should not be cleared if it includes, or is necessary for the continued existence of, rare flora.

5.2 Clearing in Environmentally Sensitive Areas Environmentally Sensitive Area’s (ESA’s) are subject to definition under Section 51B of the Environmental Protection Act (1986) and may include areas such those requiring special management attention to protect important scenic values, fish and wildlife resources, historical and cultural values, and other natural systems or processes. The Department of Environment and Conservation (2009b) does not identify any Environmentally Sensitive Area (ESA) within or adjacent to the Study Area.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 19 Preliminary Environmental Impact Assessment 6. Potential Impacts

Table 7 identifies the potential impacts for those aspects considered relevant to the Project. This section includes references to recommendations where applicable.

Table 7 Assessment of Environmental and Social Aspects and Impacts

Aspect Evaluation of Potential Impact

Land Use and The surrounding land is either unallocated crown land or pastoral lease acquisition holding. The road upgrades will be under taken on MRWA road reserve and as such current land use and land acquisition is not an issue for this part of the Project. Areas 1 to 3 are located on Mt Barnett Pastoral Lease and Areas 4, 6, 7 and 8 are located within Gibb River Pastoral Lease (refer to Section 7, Recommendation 1).

Surface waters/ No permanent wetlands occur within the Study Area. Some minor drainage ephemeral rivers /creek lines traverse the Gibb River Road within the Study Area. However, these are only likely to flow following major rainfall events. While some sedimentation risk / erosion may occur, the impact on surface waters and drainage lines is expected to be minimal. Refer to Section 7, Recommendation 2.

Groundwater Proposed works are not expected to impact on groundwater resources. Refer to Section 7, Recommendation 3.

Reserves and There were no National Parks or Conservation Reserves identified conservation areas within or in close proximity to the Study Area.

Vegetation Clearing The extent of clearing required for this Project is relatively minor compared to the large areas of native vegetation adjacent to the Study Area and within the Central Kimberley IBRA region. Following assessment against the DEC’s “Ten Clearing Principles” (refer to Appendix E) it is considered that clearing of native vegetation for the proposed Project may potentially be at variance with Clearing Principle (c) being; The area should not be cleared if it includes, or is necessary for the continued existence of, rare flora. Rehabilitation of material areas will be required after Project construction. Refer to Section 7, Recommendations 4, 5 and 6.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 20 Preliminary Environmental Impact Assessment Aspect Evaluation of Potential Impact

Flora The DEC database search recorded no known populations of Declared Rare Flora or Priority flora within the Study Area. However One Declared Rare Flora (DRF) and 29 Priority species were identified from the search area, within the vicinity of the Study Area. No field work has been conducted in the Study Area as part of the commission. DRF, Priority Flora and threatened flora species habitat may exist within the proposed Study Area. Therefore, it is recommended that a targeted flora survey be undertaken at the end of the wet season to identify the presence of threatened flora species within the Survey Area (refer to Section 7, Recommendation 6).

Weeds Weed species in the Study Area will be most dominant along the margins of the Gibb River Road. Weed spread will be an issue that will require management during the clearing and construction phase. It is necessary to reduce the risk of weed spread from disturbed areas to less disturbed areas via vehicles, machinery and soil movement. Weed control should be included in the CEMP for the Project. Refer to Section 7, Recommendation 7

Fauna The amount of area required for this Project is small relative to the amount of good quality habitat surrounding the Study Area and the impacts on fauna species are expected to be minimal. Although the clearing of vegetation has the potential to have a direct impact on fauna, the Project is unlikely to have a significant impact on the biodiversity value at the species and ecosystem levels in the region. Refer to Section 7, Recommendation 8.

European Heritage No World Heritage Properties or European heritage sites of significance are present in the Study Area. One heritage place from the Heritage Council of Western Australia – Places Database was identified within the vicinity of the Study Area, namely:

» Mount Barnett Station Homestead: Place No: 09776. This heritage place is located on the LHS of the Gibb River Road, between Galvans Gorge and Barnett River Gorge (Figure 2). This heritage place is not located within the Study Area and is unlikely to be impacted by the proposed Project works.

Aboriginal Heritage Four Aboriginal heritage sites are identified as potentially located within the Study Area. Refer to Section 7, Recommendation 9.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 21 Preliminary Environmental Impact Assessment Aspect Evaluation of Potential Impact

Construction phase During the construction phase of the proposed works, activities have impacts – fire the potential to cause adverse environmental/social impacts. It is management, fuel considered that these can be adequately managed under a project and chemical specific Construction Environmental Management Plan (CEMP) (refer storage, and waste to Section 7, Recommendation 7). disposal.

Noise and Vibration Given that the majority of the Study Area is either unallocated crown land, or pastoral lease holding, the potential for construction noise and vibration to cause significant impacts is considered minimal. Measures to reduce this risk, particularly where structures are in proximity to the works should be implemented (refer to Section 7, Recommendation 7).

Dust Dust will be generated during the roadworks. Main Roads will control dust during constriction via the implementation of a standard CEMP and areas that no longer require construction will be rehabilitated (refer to Section 7, Recommendations 5 and 7).

Visual Amenity Whilst proposed works and clearing of vegetation will impact upon the visual amenity, this aspect is not considered to be significant given that much of the Study Area is unpopulated and the impact will be temporary. Rehabilitation after construction works will reduce the impacts on visual amenity. Refer to Section 7, Recommendation 5).

Public safety and The construction phase of the Project may create some public safety risk and risk issues. Applying traffic management and signage to Main Roads standards will be necessary to manage these risks throughout the implementation of the Project.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 22 Preliminary Environmental Impact Assessment 7. Recommendations and Approvals Required

Table 8 indicates that it is unlikely that approvals from government agencies are required.

Table 8 Recommendations and Approvals required for the Project

Recommendation Agency Relevant Agency Required / Referral

1. MRWA will need to liaise with the pastoral lease holders if No Pastoral Lease works are to be undertaken on Mt Barnett and /or Gibb Holders Pastoral Leases

2. Main Roads will need to apply for a Section 17 Permit to Yes Department of Water Interfere with Bed and Banks under the Rights in Water (DoW) Irrigation Act 1914 if road upgrades impact on the Bed and Banks of Barnett River.

3. If groundwater is required, Main Roads will need to apply Yes DoW for a 26D Licence under the Rights in Water and Irrigation Act 1914 to construct bores in this area and/or apply for a 5C Licence for abstraction of water.

4. It is recommended that works be undertaken for this No N/A Project in the dry season, reducing the chance for weather to adversely impact construction activities.

5. Rehabilitation of side access tracks and material source No N/A areas will be required after Project works. It is suggested that rehabilitation be undertaken at the end of the dry season to ensure that native flora can take advantage of wet season rainfall.

6. It is recommended that MRWA undertake a targeted Yes (where Department of survey for rare and priority flora species (particularly those found to be Environment and identified from the area, listed in Table 11), to be undertaken at significant Conservation (DEC) after the wet season. variance)

7. Development of a Construction Environmental No N/A Management Plan by Main Roads and its contractor.

8. Main Roads should protect fauna and fauna habitat during No DEC construction works in accordance with a Construction Environmental Management Plan

9. It is recommended that Main Roads Project Officer liaise Yes (if Department of with the Main Roads Heritage Liaison Officer and appropriate impacts to Indigenous Affairs representatives of the local Aboriginal community to Aboriginal (DIA) determine the level of impact on Aboriginal heritage within the heritage are Study Area and comply with any recommendations made in to occur). relation to Aboriginal heritage requirements.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) 23 Preliminary Environmental Impact Assessment 8. Stakeholder Consultation

During the preparation of this PEIA, GHD contacted the following stakeholders. The responses to our request for comments are detailed as follows: Mr Troy Sinclair, Ms Sarah Greenwood & Ms Sharon Ferguson, Conservation Officers – DEC No additional comments were made for the Project by DEC conservation officers. Mr Sinclair noted that an issue to consider during desktop assessment is even though you may not find many Priority flora on the DEC databases in nearby similar vegetation communities, some consideration should be given to previous sampling effort in these areas. If there are limited general flora records in the vicinity, then inadequate sampling has previously been undertaken to record Priority flora in the vegetation communities. Mr Sinclair mentioned that this should be seen as a risk issue in the MRWA proposal. Post operation management of gravel pits has always been a previous issue along the Gibb River Road, with the public using them as overnight camping spots. Rehabilitation and closure of any new pits will resolve this issue. Mr Andrew Arnold, UXO Liaison Officer – FESA.

Mr Arnold advised that the proposed Study Area is well outside any known or suspected UXO Contaminated sites and that their records indicated no known use of the Gibb River region by the Department of Defence for training purposes, or of any hostile bombardment activity by enemy forces during World War II., It is considered by Fire and Emergency Services Authority (FESA) that the risk of UXO is negligible and has no objections to the proposed Project.

Conservation Code Description

R: Declared Rare Flora – Extant Taxa which have been adequately searched for and are deemed Taxa to be in the wild either rare, in danger of extinction, or otherwise in need of special protection, and have been gazetted as such.

X: Declared Rare Flora – Taxa which have not been collected, or otherwise verified, over the Presumed Extinct Taxa past 50 years despite thorough searching, or of which all known wild populations have been destroyed more recently, and have been gazetted as such.

P1: Priority One – Poorly Taxa which are known from one or a few (generally <5) Known Taxa populations which are under threat, either due to small population size, or being on lands under immediate threat, e.g. road verges, urban areas, farmland, active mineral leases, etc., or the plants are under threat, e.g. from disease, grazing by feral animals etc. May include taxa with threatened populations on protected lands. Such taxa are under consideration for declaration as ‘rare flora’, but are in urgent need of further survey.

P2: Priority Two – Poorly Taxa which are known from one or a few (generally<5) Known Taxa 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 Taxa which are known from several populations, and the taxa are Known Taxa not believed to be under immediate threat (i.e. not currently endangered), either due to the 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: 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.

Fauna Conservation Codes and Threatened Fauna Species

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) Preliminary Environmental Impact Assessment EPBC Act Fauna Conservation Categories

Listed threatened species and ecological communities An action will require approval from the Environment Minister if the action has, will have, or is likely to have a significant impact on a species listed in any of the following categories:

» Extinct in the wild,

» Critically Endangered,

» Endangered, or

» Vulnerable. See Table 9.

Critically endangered and endangered species An action has, will have, or is likely to have a significant impact on a critically endangered or endangered species if it does, will, or is likely to:

» lead to a long•term decrease in the size of a population, or

» reduce the area of occupancy of the species, or

» fragment an existing population into two or more populations, or

» adversely affect habitat critical to the survival of a species, or

» disrupt the breeding cycle of a population, or

» modify, destroy, remove, isolate or decrease the availability or quality of habitat to the extent that the species is likely to decline, or

» result in invasive species that are harmful to a critically endangered or endangered species becoming established in the endangered or critically endangered species' habitat*, or

» interfere with the recovery of the species.

*Introducing an invasive species into the habitat may result in that species becoming established. An invasive species may harm a critically endangered or endangered species by direct competition, modification of habitat, or predation.

Vulnerable species An action has, will have, or is likely to have a significant impact on a vulnerable species if it does, will, or is likely to:

» lead to a long•term decrease in the size of an important population of a species, or

» reduce the area of occupancy of an important population, or

» fragment an existing important population into two or more populations, or

» adversely affect habitat critical to the survival of a species, or

» disrupt the breeding cycle of an important population, or

» modify, destroy, remove or isolate or decrease the availability or quality of habitat to the extent that the species is likely to decline, or

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) Preliminary Environmental Impact Assessment » result in invasive species that are harmful a vulnerable species becoming established in the vulnerable species' habitat*, or

» interferes substantially with the recovery of the species. An important population is one that is necessary for a species' long•term survival and recovery. This may include populations that are:

» key source populations either for breeding or dispersal,

» populations that are necessary for maintaining genetic diversity, and/or

» populations that are near the limit of the species range. *Introducing an invasive species into the habitat may result in that species becoming established. An invasive species may harm a vulnerable species by direct competition, modification of habitat, or predation.

Listed Migratory species An action will require approval from the Environment Minister if the action has, will have, or is likely to have a significant impact on a listed migratory species. Note that some migratory species are also listed as threatened species. The criteria below are relevant to migratory species that are not threatened. An action has, will have, or is likely to have a significant impact on a migratory species if it does, will, or is likely to:

» substantially modify (including by fragmenting, altering fire regimes, altering nutrient cycles or altering hydrological cycles), destroy or isolate an area of important habitat of the migratory species, or

» result in invasive species that is harmful to the migratory species becoming established* in an area of important habitat of the migratory species, or

» seriously disrupt the lifecycle (breeding, feeding, migration or resting behaviour) of an ecologically significant proportion of the population of the species. An area of important habitat is: 1. habitat utilised by a migratory species occasionally or periodically within a region that supports an ecologically significant proportion of the population of the species, or 2. habitat utilised by a migratory species which is at the limit of the species range, or 3. habitat within an area where the species is declining. Listed migratory species cover a broad range of species with different life cycles and population sizes. Therefore, what is an ecologically significant proportion of the population varies with the species (each circumstance will need to be evaluated). *Introducing an invasive species into the habitat may result in that species becoming established. An invasive species may harm a migratory species by direct competition, modification of habitat, or predation.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) Preliminary Environmental Impact Assessment The Commonwealth Marine environment An action will require approval from the Environment Minister if:

» the action is taken in a Commonwealth marine area and the action has, will have, or is likely to have a significant effect on the environment, or

» the action is taken outside a Commonwealth marine area and the action has, will have, or is likely to have a significant effect on the environment in a Commonwealth marine area. An action has, will have or is likely to have a significant impact on the environment in a Commonwealth marine area if it does, will, or is likely to:

» result in a known or potential pest species becoming established in the Commonwealth marine area*, or

» modify, destroy, fragment, isolate or disturb an important or substantial area of habitat such that an adverse impact on marine ecosystem functioning or integrity in a Commonwealth marine area results, or

» have a substantial adverse effect on a population of a marine species or cetacean including its life cycle (e.g. breeding, feeding, migration behaviour, and life expectancy) and spatial distribution, or

» result in a substantial change in air quality** or water quality (including temperature) which may adversely impact on biodiversity, ecological integrity, social amenity or human health, or

» result in persistent organic chemicals, heavy metals, or other potentially harmful chemicals accumulating in the marine environment such that biodiversity, ecological integrity, social amenity or human health may be adversely affected.

*Translocating or introducing a pest species may result in that species becoming established.

**The Commonwealth marine area includes any airspace over Commonwealth waters

Conservation Code Description

Schedule 1 “…fauna that is rare or likely to become extinct, are declared to be fauna that is in need of special protection.”

Schedule 2 “…fauna that is presumed to be extinct, are declared to be fauna that is in need of special protection.”

Schedule 3 “…birds that are subject to an agreement between the governments of Australia and Japan relating to the protection of migratory birds and birds in danger of extinction, are declared to be fauna that is in need of special protection.”

Schedule 4 “…fauna that is in need of special protection, otherwise than for the reasons mentioned [in Schedule 1 – 3]”

Table 13 DEC Priority Fauna Codes

(Species not listed under the Wildlife Conservation Act (1950), but for which there is some concern).

Conservation Code Description

Priority 1 Taxa with few, poorly known populations on threatened lands.

Priority 2 Taxa with few, poorly known populations on conservation lands. 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 degradation, e.g. national parks, conservation parks, nature reserves, State forest, vacant Crown Land, water reserves, etc.

Priority 3 Taxa which are known from few specimens or sight records, some of which are on lands not under immediate threat of habitat destruction or degradation.

Priority 4 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.

Priority 5 Taxa in need of monitoring. 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.

Family Scientific Name EPBC Act WC Act DEC Comment 1999 1950

Birds

ACCIPITRIDAE Erythrotriorchis Vulnerable Schedule 1 This species prefers forest and woodland with a mosaic of radiatus vegetation types, large prey populations (birds), and Migratory permanent water. The vegetation types include eucalypt (Red Goshawk) woodland, open forest, tall open forest, gallery rainforest, swamp sclerophyll forest, and rainforest margins (Department of the Environment, Water, Heritage and the Arts, 2009b). This species may occur in the Study Area as a transient visitor.

BURHINIDAE Burhinus grallarius Priority 4 The range of the Bush Stone•curlew extends throughout Australia. It was formerly quite common, but has declined in (Bush Stonecurlew) numbers through loss of habitat and predation by foxes and feral cats. Today it is more abundant in the north and inhibits lightly timbered open woodlands (Australian Museum, 2003). This species may occur in the Study Area

FALCONIDAE Falco hypoleucos Priority 4 The distribution of the Grey Falcon is centred on inland drainage systems where there is an average annual rainfall of (Grey Falcon) less than 500 mm. There it frequents timbered lowland plains, particularly acacia shrublands that are crossed by tree•lined watercourses (Department of the Environment, Water, Heritage and the Arts, 2009b). Unlikely to occur in Study Area due to lack of suitable habitat.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) Preliminary Environmental Impact Assessment Family Scientific Name EPBC Act WC Act DEC Comment 1999 1950

MALURIDAE Malurus coronatus Vulnerable Priority 4 The Purple•crowned Fairy•wren (western) is estimated to occur coronatus in thirteen locations: the upper Fitzroy River (including the Adcock River, Traine River and Hann River), Isdell River, (Purple•crowned Fairy• Berckelman River, Drysdale River, Durack River, Pentecost wren (western ssp)) River, Chamberlain River, King George River, Berkeley River, Forrest River, Bow River, Ord River and Victoria River systems (Department of the Environment, Water, Heritage and the Arts, 2009c). This species is likely to occur within the Study Area, especially near watercourses.

PASSERIDAE Erythrura gouldiae Endangered Schedule 1 Between 100 and 200 adult Gouldian finches are estimated to exist at Mornington Wildlife Sanctuary (located south•east of (Gouldian Finch) Migratory the Study Area) and around Gibb River Road (Department of the Environment, Water, Heritage and the Arts, 2009b). This species is likely to occur within the Study Area, especially near watercourses.

ROSTRATULIDAE Rostratula australis Vulnerable This species is usually found in shallow inland wetlands, either freshwater or brackish, and often the wetlands are of a type (Australian Painted that is temporary or infrequently filled with water (Department Snipe) of the Environment, Water, Heritage and the Arts, 2009b). Unlikely to occur in Study Area due to lack of suitable habitat.

Mammals

DASYURIDAE Dasyurus hallucatus Endangered Schedule 1 The species' preferred habitat consists of rocky escarpment, open forest and open woodland. Surveys undertaken during (Northern Quoll) 2003 and early 2004, confirmed that the Northern Quoll was still numerous in the high rainfall coastal habitat of the west Kimberley. However, populations in the more arid east Kimberley region have apparently undergone a dramatic decline over the past 30 years (Department of the Environment, Water, Heritage and the Arts, 2009b). This species may be present in the Study Area.

Fish

PRISTIDAE Pristis microdon Vulnerable This species may potentially occur in all large rivers of northern Australia from the Fitzroy River (WA) to the western side of (Freshwater Sawfish) Cape York Peninsula. It is mainly confined to the main channels of large rivers. In the Fitzroy River catchment it is probably confined to the main Fitzroy River (Department of the Environment, Water, Heritage and the Arts, 2009b). This species is unlikely to occur in the Study Area.

TERAPONTIDAE Hannia greenwayi Priority 1 Very little information is known about the biology of Greenways Grunter. It was thought to be restricted to the upper reaches of (Greenway's Grunter) the Fitzroy watershed, but have since been recorded from the Calder and Isdell rivers (Storey A.W, Davies P.M and Froend, R.H, 2001). This species is unlikely to occur in the Study Area.

Caveat

The information presented in this report has been provided by a range of data sources as acknowledged at the end of the report.

This report is designed to assist in identifying the locations of places which may be relevant in determining obligations under the Environment Protection and Biodiversity Conservation Act 1999 . It holds mapped locations of World Heritage and Register of National Estate properties, Wetlands of International Importance, Commonwealth and State/Territory reserves, listed threatened, migratory and marine species and listed threatened ecological communities. Mapping of Commonwealth land is not complete at this stage. Maps have been collated from a range of sources at various resolutions.

Not all species listed under the EPBC Act have been mapped (see below) and therefore a report is a general guide only. Where available data supports mapping, the type of presence that can be determined from the data is indicated in general terms. People using this information in making a referral may need to consider the qualifications below and may need to seek and consider other information sources.

For threatened ecological communities where the distribution is well known, maps are derived from recovery plans, State vegetation maps, remote sensing imagery and other sources. Where threatened ecological community distributions are less well known, existing vegetation maps and point location data are used to produce indicative distribution maps.

For species where the distributions are well known, maps are digitised from sources such as recovery plans and detailed habitat studies. Where appropriate, core breeding, foraging and roosting areas are indicated under "type of presence". For species whose distributions are less well known, point locations are collated from government wildlife authorities, museums, and non• government organisations; bioclimatic distribution models are generated and these validated by experts. In some cases, the distribution maps are based solely on expert knowledge.

Only selected species covered by the migratory and marine provisions of the Act have been

http://www.environment.gov.au/cgi•bin/erin/ert/epbc/epbc_report.pl?searchtype=point;... 6/04/2009 EPBC Act Protected Matters Report Page 6 of 7

mapped.

The following species and ecological communities have not been mapped and do not appear in reports produced from this database:

l threatened species listed as extinct or considered as vagrants l some species and ecological communities that have only recently been listed l some terrestrial species that overfly the Commonwealth marine area l migratory species that are very widespread, vagrant, or only occur in small numbers.

The following groups have been mapped, but may not cover the complete distribution of the species:

l non•threatened seabirds which have only been mapped for recorded breeding sites; l seals which have only been mapped for breeding sites near the Australian continent.

Such breeding sites may be important for the protection of the Commonwealth Marine environment.

Attention: Mark Logue

Dear Mr Logue

REQUEST FOR RARE FLORA INFORMATION

I refer to your request of 18th March 2009 for information on rare flora in the King Leopold area. The search co•ordinates used were 160 13’ • 170 10’ S and 1250 24’ • 1260 30’ E (GDA94).

A search was undertaken for this area of (1) the Department's Threatened (Declared Rare) Flora database (for results, if any, see “DEFL” – coordinates are GDA94), (2) the Western Australian Herbarium Specimen database for priority species opportunistically collected in the area of interest (for results, if any, see “WAHERB”• coordinates are GDA94 – see condition number 9 in the attached ‘Conditions in Respect of Supply’ and (3), the Department’s Declared Rare and Priority Flora List [this list is searched using ‘place names’. This list which may also be used as a species target list, contains species that are declared rare (Conservation Code R or X for those presumed to be extinct), poorly known (Conservation Codes 1, 2 or 3), or require monitoring (Conservation Code 4) – for results, if any, see “DP List”]. The results are attached electronically to this email.

Attached also are the conditions under which this information has been supplied. Your attention is specifically drawn to the seventh point, which refers to the requirement to undertake field investigations for the accurate determination of rare flora occurrence at a site. The information supplied should be regarded as an indication only of the rare flora that may be present and may be used as a target list in any surveys undertaken.

The information provided does not preclude you from obtaining and complying with, where necessary, land clearing approvals from other agencies.

An invoice for $300 (plus GST) to supply this information will be forwarded.

It would be appreciated if any populations of rare flora encountered by you in the area could be reported to this Department to ensure their ongoing management.

If you require any further details, or wish to discuss rare flora management, please contact Dr Ken Atkins, Manager, Species and Communities Branch, on (08) 9334 0455.

Yours faithfully BA Long ...... for Keiran McNamara DIRECTOR GENERAL

CONSERVATION CODES

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.

X: Declared Rare Flora • Presumed Extinct Taxa Taxa which have not been collected, or otherwise verified, over the past 50 years despite thorough searching, or of which all known wild populations have been destroyed more recently, and have been gazetted as such.

1: Priority One • Poorly known Taxa 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, e.g. road verges, urban areas, farmland, active mineral leases, etc., or the plants are under threat, e.g. from disease, grazing by feral animals, etc. May include taxa with threatened populations on protected lands. Such taxa are under consideration for declaration as 'rare flora', but are in urgent need of further survey.

2: 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.

3: 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), either due to the 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.

4: 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.

Note, the need for further survey of poorly known taxa is prioritised into the three 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 the current information.

Dear Mark

REQUEST FOR THREATENED FAUNA INFORMATION

I refer to your request of 18th March for information on threatened fauna occurring in the Galvins Gorge to Barnett Gorge shapefile provided.

A search was undertaken for this area of the Department's Threatened Fauna database, which includes species which are declared Rare as ' or likely to become extinct (Schedule 1)', Birds ' protected under an international agreement (Schedule 3)', and 'Other specially protected fauna (Schedule 4)'.

Attached also are the conditions under which this information has been supplied. Your attention is specifically drawn to the sixth point that refers to the requirement to undertake field investigations for the accurate determination of threatened fauna occurrence at a site. The information supplied should be regarded as an indication only of the threatened fauna that may be present.

An invoice for $200.00 (plus GST), being the set charge for the supply of this information, will be forwarded.

It would be appreciated if any populations of threatened fauna encountered by you in the area could be reported to this Department to ensure their ongoing management.

If you require any further details, or wish to discuss threatened fauna management, please contact my Principal Zoologist, Dr Peter Mawson on 08 93340421.

Yours sincerely

……………………………………… for Keiran McNamara DIRECTOR GENERAL Department of Environment and Conservation

THREATENED FAUNA INFORMATION

Conditions In Respect Of Supply Of Information

* All requests for data to be made in writing to the Executive Director, Department of Environment and Conservation, Attention: Principal Zoologist, Species and Communities Branch.

* The data supplied may not be supplied to other organisations, nor be used for any purpose other than for the project for which they have been provided without the prior consent of the Executive Director, Department of Environment and Conservation

* Specific locality information for Threatened Fauna is regarded as confidential, and should be treated as such by receiving organisations. Specific locality information for Threatened Fauna may not be used in reports without the written permission of the Executive Director, Department of Environment and Conservation. Reports may only show generalised locations or, where necessary, show specific locations without identifying species. The Principal Zoologist is to be contacted for guidance on the presentation of Threatened Fauna information.

* Receiving organisations should note that while every effort has been made to prevent errors and omissions in the data, they may be present. The Department of Environment and Conservation accepts no responsibility for this.

* Receiving organisations must also recognise that the database is subject to continual updating and amendment, and such considerations should be taken into account by the user.

* It should be noted that the supplied data do not necessarily represent a comprehensive listing of the Threatened Fauna of the area in question. Its comprehensiveness is dependent of the amount of survey carried out within a specified area. The receiving organisation should employ a biologist/zoologist, if required, to undertake a survey of the area under consideration.

* Acknowledgment of the Department of Environment and Conservation as the source of data is to be made in any published material. Copies of all such publications are to be forwarded to the Department of Environment and Conservation, Attention; Principal Zoologist, Species and Communities Branch.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) Preliminary Environmental Impact Assessment (a) Native vegetation should not be cleared if it comprises a high level of biological diversity.

Comments This Project is not considered to be at variance with this clearing principle given the desktop information to hand, particularly given the extent of the vegetation in the IBRA region (refer to Table 3).

Methodology Desktop assessment of available information

(b) Native vegetation should not be cleared if it comprises the whole or a part of, or is necessary for the maintenance of, a significant habitat for fauna indigenous to Western Australia.

Comments This Project is not considered to be potentially at variance with this clearing principle given the desktop information to hand.

Although the vegetation in the Survey Area is likely to provide shelter for a large variety of fauna species, the dominant vegetation type located within the Study Area, is a common and widespread vegetation type, with an estimated 100% remaining (refer to Table 3 ). The nature of much of the clearing (being linear), adjacent to 100% vegetation extents, is unlikely to be necessary for the maintenance of a significant habitat for indigenous fauna, including several threatened and priority fauna species known to exist in the general vicinity. It is considered that the proposed works will not significantly impact the resident individual species and species distributions levels.

Methodology Desktop assessment of available information

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) Preliminary Environmental Impact Assessment (c) Native vegetation should not be cleared if it includes, or is necessary for the continued existence of, rare flora.

Comments The Project may potentially be at variance with this clearing principle, particularly given the potential clearing area extent.

One DRF species and a number of Priority species were identified as being present within the vicinity of the Study Area. There is potential for the Study Area to host DRF and Priority Flora species. No known targeted flora surveys have been undertaken particularly covering the Study Area. In order to confirm the potential variance, a field flora survey in the Study Area would need to be conducted, particularly targeting those species known to exist in the area (identified in Table 11).

Methodology Desktop assessment of available information including the EBPC Act 1999 Protected Matters Search Tool and DEC database search within the vicinity of the Study Area.

(d) Native vegetation should not be cleared if it comprises the whole or a part of, or is necessary for the maintenance of a threatened ecological community.

Comments This Project is not considered to be at variance with this clearing principle given the desktop information to hand, including the remaining extent of the regional vegetation associations.

The results of a search of the DEC’s Threatened Ecological Community (TEC) database, and theEPBC Act Protected Matters Search Tool, concluded that no TECs have been previously recorded in the Study Area. There are occurrences of the following ecological community within approximately 5 km of the search area:

» The ‘Priority 1’ ecological community – ‘Organic mound spring sedgeland community of the North Kimberley Bioregion’.

Methodology Desktop assessment of available information, including DEC database search within the vicinity of the Study Area.

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) Preliminary Environmental Impact Assessment (e) Native vegetation should not be cleared if it is significant as a remnant of native vegetation in an area that has been extensively cleared.

Comments This Project is not considered to be potentially at variance with this clearing principle, given the remaining extent of the regional vegetation associations.

Shepherd (2005) identifies that none of the vegetation associations located within the Study Area are lower than the EPA’s threshold level of 30% and in fact all are recorded at 100% of the Pre•European vegetation extent.

Methodology Desktop assessment of available information, including review of Shepherd (2005) vegetation extents.

(f) Native vegetation should not be cleared if it is growing in, or in association with, an environment associated with a watercourse or wetland.

Comments This Project is unlikely to be at significant variance with this clearing principle.

There is potential for the reformation of Gibb River Road to impact on riparian vegetation associated with Barnett River. The native vegetation that is growing is association with the river has not been identified as having significant environmental values. Other creek line vegetation similar to that located at the Study Area is present adjacent to the Study Area and in the Kimberley region in general. Given that the road already exists in the location and that minimal clearing is required, the impact upon the riparian vegetation is considered to be minimal.

Methodology Desktop assessment of available information

(g) Native vegetation should not be cleared if the clearing of the vegetation is likely to cause appreciable land degradation.

Comments This Project is not considered to be potentially at variance with this clearing principle.

Only a nominal amount of vegetation clearing will be undertaken as part of the proposed roadworks and is unlikely to be of sufficient scale to result in significant land degradation.

Methodology Desktop assessment and review of available information

61/23753/13879 Galvans Gorge to Barnett Gorge (SLK 286.5 • 324.1) Preliminary Environmental Impact Assessment (h) Native vegetation should not be cleared if the clearing of the vegetation is likely to have an impact on the environmental values of any adjacent or nearby conservation area.

Comments This Project is not considered to be potentially at variance with this clearing principle.

No conservation areas or reserves are located in the Study Area.

Methodology Desktop assessment of available information and consultation with the DEC.

(i) Native vegetation should not be cleared if the clearing of the vegetation is likely to cause deterioration in the quality of surface or underground water.

Comments This Project is not considered to be potentially at variance with this clearing principle.

Vegetation clearing is unlikely to be of sufficient scale to cause the deterioration in the quality of surface or underground water. Main Roads will ensure that there is no deterioration in surface or underground water quality.

Methodology Desktop assessment of available information

(j) Native vegetation should not be cleared if clearing the vegetation is likely to cause, or exacerbate, the incidence or intensity of flooding.

Comments This Project is not considered to be potentially at variance with this clearing principle.

Flooding currently occurs in the Study Area. The objective of the works is to reduce the risk of flooding to the road formation by the establishment of offshoot drains. The clearing of native vegetation for the Project is not considered to cause any alternation to flood duration or flood height.
