7 1. Introduction The Eglinton/South Yanchep residential development (the Project area ), is located approximately 50 km north of Perth, Western Australia in the City of Wanneroo (CoW) (Figure 1). The Project area is being developed separately as two residential estates by LandCorp: North Eglinton and South Yanchep. The North Eglinton estate is managed on behalf of LandCorp by Satterley Property Group (Satterley). The South Yanchep estate is being managed by LandCorp. As per the EPBC Approval (EPBC 2011/6021) the Project area covers a total area of ha (Figure 2), consisting of: ha of Regional Open Space 7.38 ha of indicative Public Open Space 4.64 ha of Public Open Space ha Development area. This Clearing and Management Plan (CRMP) has been prepared in accordance with condition 11 of the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) approval for the Eglinton/South Yanchep residential development (EPBC 2011/6021). At the time of preparation of the CRMP a submission had been made to DotE to vary condition 11 to remove the requirements of transporting topsoil offsite for use in revegetation, this CRMP has been prepared to address the proposed amendment. As such, the purpose of this CRMP is to address the collection, use and transfer of native seed, the collection and use of topsoil within the Project area, as well as revegetation and street scaping, with the aim of enhancing Carnaby s Black Cockatoo habitat. 1.1 Objectives The objectives of this CRMP are to provide: a commitment to the staged collection of native seed prior to clearing from within Carnaby s Black Cockatoo habitat a commitment to the collection of topsoil from 5 ha of Carnaby s Black Cockatoo habitat for use in onsite revegetation a commitment to store native seed and utilise collected seed in revegetation detailed protocols for the staged collection and use of native seed and topsoil a commitment to revegetate at least 5 ha of native vegetation within public open space (POS) areas or regional open space (ROS) in the Project area a commitment to at least 50% planting of trees and shrubs in street scaping to include plants known to be primary feeding plants for Carnaby s Black Cockatoo. 1.2 Land details The Project area is located within the north-west growth corridor, an area subject to expanding urban development, including the Alkimos development to the south. The Project area is located on the coast, and is bounded by the Indian Ocean to the west and by the Mitchell Freeway to the east. Marmion Avenue dissects the centre of the Project area, between the Eglinton and South Yanchep developments (Table 1).

8 1.3 Statutory and policy context Alkimos-Eglinton MRS Amendment 1029/33 The Eglinton/South Yanchep Project area is located within the wider Alkimos-Eglinton District which was the subject of Metropolitan Regional Scheme Amendment 1029/33. This MRS Amendment was assessed by the EPA under s 48A of the Environmental Protection Act 1986 (EP Act), approved by the Minister for Environment on 24 April 2006 (Ministerial Statement 722), and gazetted by the Western Australian Government on 23 June The result of the EPA assessment was the identification of regionally significant areas of the site, principally identified for their geoheritage and biodiversity values. The environmental conditions for MRS Amendment 1029/33 published by the WA Minister for the Environment; therefore, requires the inclusion of the regional significant areas in Parks and Recreation and Public Purpose zonings in the MRS and states that these areas shall only be used for conservation, landscape and complimentary purposes Alkimos-Eglinton District Structure Plan Following from the MRS Amendment the Project area was also subject to the Alkimos-Eglinton District Structure Plan (DSP), adopted by the Western Australian Planning Commission (WAPC) in August The DSP outlines the broad principles for the management of the three Alkimos-Eglinton ROS areas as follows: to be preserved for conservation, landscape and complimentary purposes to preserve the majority of the ROS in its natural state, allowing for retention of representative examples of the vegetation, flora and habitats currently present on the site. to provide linkages across the site for fauna movement, contributing to the protection of biodiversity. to provide adequate and appropriate public access to ROS for sustainable passive recreation and protect the values of the ROS from uncontrolled pedestrian access by provided Dual Use Paths (DUP) in and through the ROS that connect to the DUP network in the adjacent areas to erect appropriate fencing to discourage uncontrolled access to create a clear boundary between the ROS and private land to design edges between ROS and adjacent urban areas to minimise disturbance to the ecological values of the ROS to protect the linkage values and biodiversity values of the ROS Environment Protection and Biodiversity Conservation Act 1999 The Eglinton/South Yanchep Project area was referred to the Commonwealth Department of Sustainability, Environment, Water, Population and Communities (DSEWPaC, now the Department of the Environment [DotE]) on 4 July 2011 and approved on 14 June 2013 (EPBC 2011/6021). This CRMP has been prepared in accordance with the proposed varied condition 11 of EPBC 2011/6021 as indicated in Table 2. 2-Jul-14 2

12 2. Carnaby s Black Cockatoo 2.1 Species information Carnaby s Black Cockatoos (Calyptorhynchus latirostris) are endemic to the south-west of Western Australia. They mainly occur in uncleared remnant native eucalypt woodlands, especially those that contain salmon gum, wandoo, and in shrubland or kwongan heathland dominated by Hakea, Dryandra, Banksia and Grevillea species (DSEWPaC 2012). Current data on distribution of this species shows that there are numerous records along the Northern Swan Coastal Plain, including records in and around the Project area. 2.2 Habitat within the Project area Vegetation types within the Project area are characterised by Low Open Woodland of Banksia spp. with Tall Shrubland of Banksia sessilis and Banksia sessilis Closed Heath to Tall Shrubland, which support flora species known to be a food source for Carnaby s Black Cockatoo (GHD 2011). The vegetation condition of the Project area has been assessed according to the Keighery (1994) and Trudgen (1988) scales. Based on these scales the vegetation condition within the South Yanchep area was identified as ranging from Completely Degraded to Very Good (Morgan 2007) and Completely Degraded to Excellent in the Eglinton area (GHD 2011) Foraging habitat Utilising the vegetation complex/association data and mapping produced by ATA environmental (2005) for the site, as well as additional ground-truthing reconnaissance surveys in 2009, Carnaby s Black Cockatoo habitat has been mapped within the Project area by Eco Logical Australia (2010). This mapping demonstrates that the Project area contains ha of potential Carnaby s Black Cockatoo foraging habitat, of which ha will be cleared. The balance 65.6 ha of foraging habitat will be retained and enhanced within ROS and POS in accordance with Attachment B to EPBC 2011/6021 (Figure 3) Potential breeding trees A total of 68 Tuart (Eucalyptus gomphocephala) trees have been identified as potential Carnaby s Black Cockatoo breeding trees within the Project area, based on the criteria of having >500 mm diameter at breast height (DBH) measurements, in accordance with the EPBC Act referral guidelines for three threatened black cockatoo species (DSEWPaC 2011). These potential breeding trees are located in the South Yanchep portion of the site. Of the 68 Tuart trees, 51 are to be retained within POS areas and 17 will be cleared (Figure 4). It is noted that no potential breeding trees to be cleared or retained onsite contain hollows that would be used by the Carnaby s Black Cockatoo during the breeding cycle. 2-Jul-14 6

15 3. Management objectives and actions The purpose of this CRMP is to address the collection, use and transfer of native seed and topsoil, as well as revegetation and street scaping, with the aim of enhancing Carnaby s Black Cockatoo habitat within the Project area. The management program for vegetation clearing and revegetation procedures has been developed to avoid or minimise the impact on Carnaby s Black Cockatoo s and their habitat during and post development of the Eglinton/South Yanchep residential estates, and to maximise the potential for the local area to continue to be utilised by Carnaby s Black Cockatoo. The Proponent has incorporated the following environment management objectives into the development to achieve these outcomes: 1. Staged collection of native seed from Carnaby s Black Cockatoo habitat planned to be cleared for use in revegetation. 2. Collection of topsoil from 5 ha of Carnaby s Black Cockatoo habitat for use in onsite revegetation 3. Transfer of any remaining native seed to DPaW or another receiving party for use in revegetation projects. 4. of at least 5 ha of Carnaby s Black Cockatoo s habitat within ROS and/or POS areas. 5. Use of plants known to be primary feeding plants for Carnaby s Black Cockatoo in at least 50% of trees and shrubs planted within the Project area. Detailed protocols, management actions and timing for these commitments are provided in the following sections. 3.1 Collection and use of topsoil and native seed In accordance with the proposed varied condition 11(a), of EPBC 2011/6021, a commitment is made to the staged collection of native seed prior to clearing from within Carnaby s Black Cockatoo habitat in the Project area, and collection of topsoil from 5 ha of Carnaby s Black Cockatoo habitat for onsite revegetation following clearing. In accordance with the proposed varied condition 11(b), of EPBC 2011/6021, a commitment is made for native seed (not required for onsite use) to be stored and transported to receiving sites, as agreed with the DPaW. Native seed to be used in these areas will be sourced from Carnaby s Black Cockatoo s habitat designated to be cleared. The development is proposed to be cleared over eight years with the first stage (Figure 3) and all associated geotechnical and earthwork required to enable the other stages of development to progress proposed to commence in Detailed protocols for the staged collection and use of native seed and collection and use of topsoil have been developed consistent with the proposed varied condition 11(c) of EPBC 2011/6021. These are outlined in Table 3 and Table 4. Management measures relating to the protection of habitat with POS or ROS are provided in the Conservation Management Plan (Strategen 2014). 2-Jul-14 9

16 Table 3 Management actions for the staged collection and use of native seed Actions Timing Responsibility Seek quotations and engage licensed by the DPaW to collect seed from Carnaby s Black Cockatoo habitat proposed to be cleared when Carnaby s Black Cockatoo foraging species are seeding based on advice from seed collectors. Undertake staged seed collection over multiple seed collection seasons for at least six years in designated areas of Carnaby s Black Cockatoo habitat proposed to be cleared (Figure 3). Ensure seed is stored and transported in accordance Industry of Western Australia (RIAWA) standards to ensure seed viability, until required for revegetation activities (RIAWA 2014a, 2014b). Monitor native seed collected according to targets and maintain a register of volumes, species collected, locations and quantities. Undertake direct seeding and/or seedling planting for onsite revegetation sites and for street scaping in accordance with Table 5 and Table 6. Transfer any seed not required for on-site use to DPaW for use in revegetation projects. Table 4 Management actions for the staged collection and use of topsoil Project manager Project manager Actions Timing Responsibility Undertake dieback mapping of Carnaby s Black Cockatoo habitat proposed to be cleared. Identify, map and mark on-site areas suitable for sourcing topsoil for transfer (i.e. areas of Carnaby s Black Cockatoo habitat that has vegetation in Very Good to Excellent condition, is dieback free and has minimal presence and abundance of invasive weed species). Undertake staged clearing of Carnaby s Black Cockatoo habitat. Collect topsoil from 5 ha of suitable Carnaby s Black Cockatoo habitat, as described above for use in on-site revegetation areas. Ensure topsoil cuts for transfer purposes is limited to the top 10 cm to maximise the potential value of transferred topsoil (deeper cuts lead to many seeds being buried too deep for emergence in transfer sites due to mixing during collection, transport and redistribution). Ensure cleared vegetative material is mulched and stored on-site in an area designated for future landscaping or soil stabilisation or removed off-site if surplus to on-site requirements. Provide brush and/or mulch material to DPaW if required, for use in ROS areas to close unwanted access points/tracks. Clearly mark stockpiles so their source and potential use for revegetation are known (e.g. sign posts, designated areas on plan, etc). Monitor topsoil collected according to targets and maintain a register of volumes and locations. Import and spread topsoil at onsite revegetation sites in accordance with Table 5 and Table 6. Provide progress reports to the Project Manger on all clearing that has occurred including details of: map indicating the areas of clearing that has occurred volume of topsoil collected and transported for revegetation key dates from the quarter.

17 3.2 Onsite revegetation of native vegetation In accordance with condition 11(d) of approval EPBC 2011/2061, at least 5 ha of native vegetation will be revegetated within Regional Open Space (ROS) or Public Open Space (POS). The overall aim for revegetation is to improve the condition of retained area through a combination of direct seeding and seedling planting techniques. sites will be managed in accordance with the management actions described in Table 5 in order to meet targets described in Table 7. Figure 5 provides indicative areas proposed for revegetation that were indentified based on its vegetation condition and its ability to provide habitat for Carnaby s Black Cockatoo. Table 5 Management actions for onsite revegetation Actions Timing Responsibility Site preparation and maintenance Undertake dieback mapping of areas. Pre- Dieback Consultant Select onsite reference sites containing landforms and vegetation comparable (or likely to have been comparable) to those areas proposed to be revegetated. Survey the onsite reference sites to determine indicator species, density of native species, % cover of native species, native species richness and % weed cover/richness. Determine success criteria for revegetation sites based on the survey of the reference sites. Provide temporary fencing and signage around areas identified for revegetation. Undertake weed control as required at the revegetation site for at least one year prior to topsoil transfer. Continue ongoing weed control based on monitoring during the appropriate months for manual removal or spraying of herbicide and continue weed control measures until handover. Deep rip soils prior to topsoil spreading. Topsoil spreading Respread topsoil to a maximum thickness of 10 cm using appropriate machinery (e.g. loader, bobcat). Topsoil from potentially dieback risk areas will only be placed in areas which are already potentially at risk from dieback, based on dieback mapping. Spread topsoil close to, and amongst, existing vegetation in order to cover as much of the in situ soil as possible; however, avoid burial of native plants. Work parallel with site contours as far as practicable, to minimise erosion by the creation of favoured drainage routes. Rake the topsoil parallel to the slope contour to remove excessive mounds and hollows, improve water infiltration and minimise compaction. Broadcast seeding Determine the quantity of seed of various native flora species required for on-site revegetation sites. Treat seed as appropriate for each species to break dormancy and improve germination rates. The treatments could include smoking, freezing, boiling or scarifying. Undertake seed viability and germination testing if deemed necessary. Pre or during Pre and during Annually during the appropriate months post seedling planting and direct seeding until handover - once respreading of topsoil is complete Pre and during - prior to direct seeding Contractor 2-Jul-14 11

18 Actions Timing Responsibility Rake (scarify) revegetation area in preparation for direct seeding. Combine treated seed with an appropriate medium (e.g. yellow sand or vermiculite) and manually distribute (i.e. broadcast by hand) by an experienced operator, ensuring an even coverage over the whole area. Plant propagation Determine the quantity of seedling of various native flora species required for onsite revegetation sites. Engage an accredited nursery to propagate seedlings from seed collected on-site (if seedlings are included as part of the revegetation program). Ensure the quantities of plants are available for pick-up or delivery to the. Determine appropriateness of additives, which could include liquid or tablet fertiliser appropriate for native plants, water granules, soil breaker, water retainer, wetting agent. Employ additives at the appropriate time (i.e. in the hole prior to planting or upon watering-in plants). Install stakes (10-12 mm diameter) and a protective guard (plastic) around the seedlings to protect the seedlings from rabbits (Note: protective guards are only required in areas outside rabbit-proof fencing if rabbit grazing of seedlings is likely). Provide progress reports to the Project manger on revegetation activities, which include details of activities undertaken, for example: current status of the seed collection (species, quantities available, date and location of collection) weed control details (herbicide name, volumes, method, date and location, weather conditions, other relevant observations) direct seeding details (species, volumes used, date and location of seeding, conditions and other relevant observations [e.g. presence of weeds, rabbits, litter, erosion]) planting (species, numbers planted, date and location of planting, conditions and other relevant observations [e.g. presence of rabbits, litter, erosion]). - after achieving required weed control Pre and during prior to December of the year before planting Quarterly during when revegetation is occurring. Project manager Project manager 3.3 Street scaping Street scaping in the Project area will include areas of open space and will contain a mixture of canopy trees and understory vegetation of which at least 50% of the plants planted will consist of Carnaby s Black Cockatoo primary feeding species. A list of Carnaby s Black Cockatoo primary feeding plants proposed to be used in street scaping is provided in Appendix 1 or as otherwise listed within: Plants used by Carnaby s Black Cockatoo (Groom 2011) Plants for Carnaby s Search Tool (DEC 2012) Birdlife Australia (Birdlife Australia 2012). The placement of these plants will take into consideration the risk of vehicle movements to Carnaby s Black Cockatoo as detailed in the management actions in Table 6. 2-Jul-14 12

19 Table 6 Management actions for street scaping Actions Timing Responsibility Undertake landscaping using known Carnaby s Black Cockatoo primary feeding sources such that street scapes within the South Yanchep/Eglinton site are planted with 50 per cent of shrubs and trees being species suitable for the Carnaby s Black Cockatoo. Determine the quantity of plants required for particular flora species for landscaping. Arrange nursery contracts for seedling propagation if required. Ensure the quantities of plants are available for pick-up or delivered to the. Determine appropriateness of additives, which could include liquid or tablet fertiliser appropriate for native plants, water granules, soil breaker, water retainer, wetting agent or fertiliser tablets. Employ additives at the appropriate time (i.e. in the hole prior to planting or upon watering-in plants). Water seedlings when planted appropriate to climatic and soil conditions. Install stakes (10-12 mm diameter) and a protective guard (plastic) around the seedlings to protect the seedlings from rabbits (Note: protective guards are only required in areas outside rabbit-proof fencing if rabbit grazing of seedlings is likely). Primary feeding plants for the Carnaby s Black Cockatoo will not be planted along roads with speed limits exceeding 60 km/hr to minimise the risk to Carnaby s Black Cockatoo. 2-Jul-14 13

Contingency actions Contingency actions will be initiated if monitoring indicates that management measures have not been successful or effective and/or environmental targets are not being achieved (Table 9). These contingency actions have been derived from commitments outlined in proposed varied conditions 11(c), 11(d) and 11(e) of approval EPBC 2011/2061. Table 9 Trigger Contingency actions for the staged collection and use of topsoil and native seed Insufficient seed volumes collected to meet onsite revegetation targets determined in Table 7 and as required by proposed varied conditions 11(a) and (d) Insufficient topsoil volumes collected to meet onsite revegetation targets determined in Table 7 and as required by proposed varied conditions 11(a) and (d) Inappropriate species used in onsite revegetation areas to meet onsite revegetation targets determined in Table 7. Inadequate native flora species richness and/or cover to achieve targets determined in Table 7 based on the reference site*. Unacceptable weed infestations in on-site revegetated sites based on the targets determined in Table 7 at the reference site*. Less than 50% of trees and shrubs used in street scaping are primary feeding plants for Carnaby s Black Cockatoo as required by proposed varied conditions 11 (e) (i.e. survivorship of plantings less than 100%). Action 1. Identify alternative source of seed for revegetation species. 2. Seed will be sourced from a collection location which is as close as possible to the project site, and within the Swan Coastal Plain, if seed is available. 3. Species sourced will be appropriate to the objectives of this plan, particularly with respect to the establishment of Carnaby s Black Cockatoo species. 4. Broader provenances (outside the Swan Coastal Plain) will be considered as a last option if no other suitable alternatives are available. 1. Discuss with DotE the potential to review: topsoil spreading depth topsoil collection areas reducing the area for revegetation in consultation with relevant agencies continuation of revegetation without topsoil ensuring completion criteria identified in Table 7 are still met 2. Implement agreed measures 3. Monitor effectiveness of implementation of agreed measures. 1. Identify cause. 2. Remove inappropriate species and replace (if required) with appropriate species. 3. Ensure inappropriate species are not used in future. 1. Identify cause. 2. Implement approach to remedy cause, which could include: collecting additional provenance seed for direct seeding or plant propagation to compensate for the insufficient native plant species richness and/or cover undertake infill seedling planting and direct seeding application of fertilisers or wetting agents etc. in consultation with a suitably qualified revegetation specialist or DPaW. 3. Monitor success of remedy. 1. Investigate cause (e.g. adjacent sources of weed seed). 2. Implement measures to prevent further weed infestations (e.g. screening fencing, weed control in adjacent land), as practicable in consultation with a suitably qualified revegetation specialist. 3. Undertake weed control activities as required. 1. Identify cause. 2. Undertake infill planting with Carnaby s Black Cockatoo primary feeding species. 3. Ensure 50% proportion is maintained in future. * Weeds will be controlled in revegetation areas prior to planting. Activation of the inadequate native flora species or the unacceptable weed infestations trigger after planting will be determined by vegetation monitoring. Baseline native/weed species richness and cover will be quantified via the establishment of reference monitoring quadrats within vegetated areas prior to (Refer to Table 5). If, following a monitoring event within revegetated areas, there is greater than 25% difference between native/weed species richness and/or density within revegetation quadrats in comparison to reference quadrats (i.e. 25% lower for native species and 25% higher for weed species); the relevant trigger will be activated. 2-Jul-14 17

24 6. Plan implementation This CRMP will be implemented by LandCorp (and Satterley Property Group on behalf of LandCorp for North Eglinton) for the ROS and POS areas until responsibility of the ROS and POS are transferred. It is proposed that the ROS will be transferred to the Department of Parks and Wildlife (DPaW) and the POS to the City of Wanneroo (CoW) (Table 10). Table 10 Type Habitat in ROS Habitat in POS Long-term management and timeframes for implementation Responsible for long term management Management of the habitat is proposed to be transferred to DPaW within 5 years of the substantial commencement of the action. Management of the habitat in POS areas is proposed to be handed over to CoW within 5 years of the substantial commencement of the action. Legal mechanisms for protection in the future Ceded to the crown and vested in DPaW as Regional Open Space for the purposes of local conservation. CoW Local Planning Policy requires Conservation Management Plans to be prepared for each of the local POS areas that include designated local conservation areas. 6.1 Roles and responsibilities All s and staff will be required to operate in accordance with this CRMP. Key personnel and responsibilities are described in the following sections: Project manager The primary responsibilities of the project manager include: act as primary liaison between DotE, CoW, DPaW, and revegetation ensure all and revegetation contracts contain relevant environmental management provisions review reports provided by the Review progress activity reports prepared by revegetation overall accountability to ensure native seed and topsoil collection is undertaken in appropriate areas ensure all site personnel are aware of the requirements of the CRMP and related management plans report to DotE in accordance with condition 3 and 4 of EPBC 2011/ The primary responsibilities of the include: assist the project manager to ensure activities do not adversely affect Carnaby s Black Cockatoo habitat being retained within ROS or POS areas ensure all site personnel are aware of the requirements of the CRMP and related plans provide support to the project manager and CoW as required during the phase. Provide reports on clearing activities to the Project manager including details of: map indicating the areas of clearing that has occurred volume of topsoil collected and transported for revegetation key dates of. 2-Jul-14 18

25 6.1.3 Dieback consultant The primary responsibilities of the dieback consultant include: Undertaking dieback mapping of Carnaby s habitat proposed to be cleared and revegetation areas inform Project Manager of any areas mapped that are at risk of Dieback The primary responsibilities of the revegetation include: ensure native seed is collected, stored and transported as per the procedures outlined in this plan unless otherwise agreed by the CoW to provide progress activity reports to the project manager which include details of activities undertaken, including, for example: current status of the seed collection (species, quantities available, date and location of collection) weed control details (herbicide name, volumes, method, date and location, weather conditions, other relevant observations) direct seeding details (species, volumes used, date and location of seeding, conditions and other relevant observations [e.g. presence of weeds, rabbits, litter, erosion]) planting (species, numbers planted, date and location of planting, conditions and other relevant observations [e.g. presence of rabbits, litter, erosion]) ensure all revegetation personnel are aware of the requirements of the CRMP and related management plans ensure revegetation activities meet performance targets provide support to the project manager and DPaW as required during the phase. Department of Parks and Wildlife It is proposed that the primary responsibility of DPaW includes: provide for the long term management and protection of habitat within the ROS. City of Wanneroo It is proposed that the primary responsibility of CoW includes: provide for the long term management and protection of habitat within the POS. 2-Jul-14 19
