2. Purpose of clearance
2.1 Description SA Water is proposing to build a new pipeline to connect the Middle River and Penneshaw water supply systems on Kangaroo Island.
2.2 Background The Middle River system distributes water from the Middle River Reservoir to Kingscote, Parndana and Brownlow in the central part of Kangaroo Island. The Penneshaw system distributes water from the Penneshaw desalination plant to Penneshaw on the Dudley Peninsula in the eastern part of the island.
SA Water completed the Kangaroo Island Long Term Water Plan in 2018 to identify actions required to ensure water security on the island for the next 25 years (SA Water 2018). The plan considered trends in water demand and supply capacity in the face of changing climate, land use and population. A priority action from the plan was to integrate the Middle River and Penneshaw systems with a pipeline. The two systems would complement each other to increase the security of water supply as well as distributing water to houses, farms and settlements along the route.
Page 5 of 77
The pipeline is planned in two stages (Figure 1). Stage 1 extends from the Middle River water main on Playford Highway near Kangaroo Island Airport along Arranmore Road and Hog Bay Road to Pelican Lagoon. Stage 2 extends from Pelican Lagoon along Hog Bay Road to reach the desalination plant water storage at Charing Cross Road, Kangaroo Head.
A Stage 1 vegetation clearance application was initially prepared for KI Links by Botanical Enigmerase and approved by the Native Vegetation Council on 6 March 2019 (NVR 2019/3016/520). Since this approval was given, SA Water has assumed ownership of the project and made changes to the pipeline's design. This data report is a replacement application for Stage 1 and a new application for Stage 2.
Related, future options to further augment water supply and security are: • relocating the Penneshaw desalination plant to the Earth Bank Storage facility at the intersection of Hog Bay Road and Charing Cross Road (Figure 1) and increasing its capacity; and • a pipeline to supply water to American River.
2.3 General location map Figure 1 provides an overview of the route within the regional setting. Figures 2 and 3 shows the Stage 1 and Stage 2 pipeline sections in the context of towns, conservation reserves and roads.

2.4 Details of the proposal The pipeline extends from the intersection of Playford Highway at Cygnet River along Arronmore Road and Hog Bay Road to the Penneshaw desalination plant Earth Bank Storage (EBS) at the intersection of Charing Cross Road. The pipeline will be constructed in the Commissioner of Highways roads under the care and control of the Department for Infrastructure and Transport and Kangaroo Island Council. The route comprises sections of the following roads: • Arronmore Road; • Hog Bay Road; and • Charing Cross Road The pipeline will be buried in a back-filled trench excavated by a Vermeer. The construction methodology is based on a 0.375 m pipe and a maximum trench width of 1.0 m. The Vermeer utilises a trencher between two tracks with a maximum impact width of 2.9 m, i.e. 0.96 m either side of the trench. It is planned to use a loadout conveyor to load excavated material directly from the trench to a truck (SA Water 2020). Three pipeline alignment options are available to manage impacts to native vegetation. • Option 1 aligns the trench in the road verge. The trench will be approximately positioned on the outer side of the white marker posts. This option requires a corridor up to 3.3 m wide from the edge of the bitumen. This alignment is preferred where native vegetation is of low significance or absent. • Option 2 aligns the trench between the edge of the bitumen and the white marker posts. This option requires clearance of up to 2.3 m of roadside vegetation.
Page 8 of 77
• Option 3 aligns the trench in the sealed road, in the centre of one lane. This option does not involve vegetation clearance. It is possible that overhead branches growing in the prescribed clearance envelope of the traffic corridor may be lopped allow a safe workspace for the machinery. Option 1 is preferred from a construction and maintenance point of view. It does not require excavation and reinstatement of the road surface, it involves less disruption to traffic during construction and provides easier and safer access to the pipeline after construction. It is also the least costly option. However it involves the greatest potential vegetation impacts. Bends can be added to the pipeline to avoid sensitive sites. However bends increase construction difficulty, increase cost and reduce pipeline integrity.
2.5 Approvals required or obtained Native Vegetation Act 1991 (SA) An application to clear native vegetation is required under the Native Vegetation Act. Landscape Act 2019 (SA) The pipeline crosses watercourses and approvals will be required for water affecting activities under the Landscape Act. Planning, Development and Infrastructure Act 2016 (SA) Under Schedule 13 (ii) of the Planning, Development and Infrastructure Act (2016), state agency development is exempt from approval where the works involve the construction, reconstruction, alteration, repair or maintenance of any drain, pipe or underground cable. Environment Protection and Biodiversity Conservation Act 1999 (Cwth) The route passes through areas that support matters of National Environmental Significance under the EPBC Act. No significant impacts are expected but the project will be referred to the Federal Minister for the Environment. Aboriginal Heritage Act 1988 (SA) SA Water has reviewed the available information from the Department of the Premier and Cabinet – Aboriginal Affairs and Reconciliation (AAR) and Aquamap heritage layers and identified there is a low likelihood of encountering heritage in the proposed pipeline alignments. With any ground disturbing works there is potential for encountering Aboriginal heritage. SA Water’s Standard Operating Procedure (SOP) for Discovery of Aboriginal Heritage will be provided to all contractors and included as part of their Construction Environmental Management Plan. The SOP must be followed in the event that any Aboriginal heritage is discovered during the life of the project. Local Government Act (1999) (SA) SA Water is required to obtain a license from Kangaroo Island Council to make an alteration to a public road pursuant to Sections 221(2)(b) and 221(6)(b) of the Local Government Act. 2.6 Native Vegetation Regulation This project is for infrastructure in the public interest as defined under Schedule 1 Regulation 12 (34) - Infrastructure (5(1)(d) of the Native Vegetation Act.
2.7 Development Application information As a state agency project to construct a pipeline this project is exempt from approval under the Planning, Development and Infrastructure Act.

3. Method
3.1 Flora assessment Existing records of rare and threatened plants were reviewed for a 5 km search buffer along the pipeline route using NatureMaps (12 May 2019) and the EPBC Protected Matters Search Tool (12 May 2019). The Roadside Vegetation Database was also reviewed (Ecological Associates 2019). A roadside vegetation survey with Bushland Assessments was conducted on 19 November 2018 and 22, 24, 27 and 28 January 2020 (Haby and Rowley 2020a) and 3, 4 and 5 November 2020 (this report). The survey included the entire road reserve on both sides, focusing on the first 10 m from the white marker post. The route was divided into sections based on landmarks (road intersections (SS, TT, VV etc.)) and then into plant associations (sites 1, 2, 3 etc.). Road segments were further subdivided according to the distance between the road seal and the vegetation and the condition of the vegetation. Road segments were prioritised for protection according to the conservation values present. A complete species list was prepared for each plant association. Plant associations were classified according to Kangaroo Island Floristic Mapping (Willoughby et al. 2001). 3.2 Fauna assessment A database search of each vegetation clearance site with a 5 km buffer was made on 12 April 2020 and 10 December 2020 (Ecological Associates 2019) using: • NatureMaps; and • the Environment Protection and Biodiversity Conservation Protected Matters Search Tool. A detailed fauna survey was undertaken of representative sites on the 23rd and 24th of September 2019 (Ecological Associates 2019). The roadside was walked. Standard Biological Survey of South Australia methodology (Owens 2000) for birds was undertaken at seven locations, with at least two person-hours spent in the morning and late afternoon in each site. In addition any bird species opportunistically observed outside these areas were noted. Observations were made in the field of other vertebrate taxa (mammals, reptiles, amphibians) based on sightings, tracks, scats or traces. Several specific habitat attributes for fauna were also targeted during field survey. All active termite mounds observed within 5 metres of the road edge were noted, along with any other observations outside this area. A GPS location was recorded for each termite mound, as well as distance from the existing verge. The findings of this survey were extrapolated to similar habitats and landscapes in the remainder of the route.

4. Assessment Outcomes
4.1 Vegetation Assessment General description of the vegetation, the site and matters of significance The pipeline will be constructed in public road reserves. Route Description Stage 1 commences at the connection to the Middle River Water Main is 12 km south-west of Kingscote at the intersection of Arronmore Road and the Playford Highway. The route follows Arronmore Road along the northern boundary of Kangaroo Island Airport then turns south-east to the intersection of Hog Bay Road. The route continues south-east on Hog Bay Road past the township of Nepean Bay to the southern edge of Pelican Lagoon at 3222 Hog Bay Road. Stage 2 continues on Hog Bay Road, turning north to reach Eastern Cove near Island Beach. Hog Bay Road follows the coast in a north-easterly direction past Baudin Beach. At American Beach the route turns east to climbs the scarp of the Dudley Plateau and continues north to join the Earth Bank Storage at Charing Cross Road. Landforms and Vegetation The western end of the route crosses the alluvial plain of the Cygnet River near Kangaroo Island Airport. The soils are alkaline duplex soils derived from Quaternary alluvium with possibly some contribution from Tertiary marine sediments. The vegetation is predominantly Eucalyptus cneorifolia, E. diversifolia and E. albopurpurea mallee woodland in elevated areas, E. camaldulensis and E. leucoxylon woodland along drainage lines and Tecticorina arbuscula low shrublands in saline coastal areas. The route crosses the Cygnet-Snelling Fault south of the township of Nepean Bay to rise to the Gosse-Seddon Plateau. The laterised plateau is an elevated tectonic block of Cambrian rock overlain by weathered laterine, kaolinite and, in places, aeolian dunes. The vegetation is variable and includes E. cneorifolia / E. diversifolia / E. rugosa mallee, Melaleuca spp. shrublands in poorly drained areas, and heathland vegetation with Allocasuarina meulleriana in sandstone outcrops. The areas to the southwest of Pelican Lagoon comprise a jumbled sandy dunes and remnant calcreted dune cores overlain by shallow sandy Pleistocene soil. There are tidal flats associated with Pelican Lagoon and isolated salt lakes, with Salt Lagoon located to the east of Hog Bay Road. The dunes are vegetated by pasture with scattered remnants of Eucalyptus diversifolia and E. rugosa mallee and shrubby vegetation dominated by Leucopogon parviflorus and Myoporum insulare. Melaleuca sp. and samphire communities are present in tidal and waterlogged areas. From Island Beach to American Beach the route passes through recent sandy coastal dunes and ancient calcreted dunes of the Bridgewater formation with poorly draining flats. Mallee vegetation is dominated by Eucalyptus diversifolia and E. cneorifolia with E. rugosa and Callitris gracilis. Melaleuca lanceolata can form a dense midstorey. The groundlayer is typically shrubby varying to heathy, particularly in areas where the overstorey has been disturbed. Eucalyptus cneorifolia becomes the dominant species in some areas, notably to the east of Baudin Beach. Native vegetation on the road verge is mostly continuous and connected with large remnants in the broader landscape including Dudley Conservation Park. Native vegetation has mostly been from the vicinity of the road at American Beach. The Dudley Peninsula is an elevated plateau of Cambrian sandstone overlain by relict jumbled dune core topography. The dominant vegetation along Hog Bay Road is Eucalyptus cneorifolia mallee. Nomenclature Plant association nomenclature is adopted from Willoughby et al. (2001) (Table 1).

4.2 Threatened Species Assessment Review of Existing Records of Rare and Threatened Fauna Existing fauna records were reviewed to identify species of conservation significance known to occur in the region and that are potentially impacted by the works. Species were considered at risk from the project if their distribution or sightings places them in proximity to the route and if impacted vegetation provides suitable habitat. The risk assessment identified: • 20 bird species that are potentially impacted (Table 2) • 3 mammal species that are potentially impacted (Table 3) • 1 reptile species that is potentially impacted (Table 4) • No amphibian species that is potentially impacted (Table 5). The field assessment was planned to search for traces of these species and to evaluate the quality of available habitat.

Habitat Classification Fauna habitat along the route was considered in five classes Habitat Class 1. Exotic Grassland with Sparse Shrubs This habitat class occurs in disturbed areas from which native vegetation has largely been cleared. This is an exotic grassland with scattered trees or remnant or recovering Myoporum insulare, Leucopogon parviflorus, Acacia longifolia and Orthrosanthus multiflorus. This habitat class was sampled near American Beach (Section QQ and in cleared patches on the south-east side of Pelican Lagoon (Section SS). It is representative of cleared patches of Hog Bay Road south east of American River Road and cleared sections of Arronmore Road. Habitat Class 2. Kangaroo Island Narrow-leaved Mallee (Eucalyptus cneorifolia) Woodland Kangaroo Island Narrow-leaved Mallee Woodland occurs at sites throughout the route. This association tends to occur on higher ground and is the most frequently occurring plant community along the route on the Dudley Plateau and Gosse-Seddon Plateau. It also occurs on more elevated ground in the Cygnet River outwash plain. The understorey can be very sparse with scattered coastal shrubs (particularly Rhagodia candolleana), deep leaf litter and large woody debris. Kangaroo Island occurred with Melaleuca lanceolata and Callitris gracilis as co-dominant species. This habitat type was assessed at Sections RR1 and RR2 and is representative of vegetation on Hog Bay Road between Min Oil Road and American River Road, mostly on the upper slopes and crests of lateritic hills. The vegetation had a highly diverse shrubby midstorey with an open groundlayer. Habitat Class 3. Eucalyptus diversifolia and E. rugosa Mallee Eucalyptus diversifolia and E. rugosa mallee with a predominantly heathy understorey was assessed between Island Beach and Baudin Beach in Sections SS, RR2 and RR1. It also occurs on the lower slopes of the Gosse-Seddon Plateau near watercourses and wetlands in Sections WW, VV and UU. It supports a mixture of dense coastal shrubs such as Myoporum insulare and Leucopogon parviflorus or an open woodland shrubby and heathy species. Eucalyptus cosmophylla is frequently present in wetter areas and swampy clayey soils can support Gahnia trifida and Melaleuca brevifolia. Habitat Class 4. Closed coastal shrubland with emergent Eucalyptus rugosa and E. diversifolia A dense, closed shrubland of Leucopogon parviflorus, Myoporum insulare and Olearia axillaris is dominates the relict limestone dune crests which occur intermittently east of Pelican Lagoon (Section SS) and continuously south-west of Pelican Lagoon (Section SS3, SS2 and TT). Eucalyptus rugosa, E. diversifolia and Melaleuca lanceolata form a scattered and occaisonally continuous overstorey. The mid-storey is dense but the groundlayer is typically sparse. The soils are nutrient-poor, freely draining sands over limestone. Habitat Class 5. Open coastal shrubland Disturbed coastal shrubland feature patches of Leucopogon parviflorus, Myoporum insulare, Olearia axillaris and the introduced Acacia cyclops. The understorey is open with herbaceous and grassy weeds dominant. This habitat type was sampled east of Pelican Lagoon at Section QQ Site 3 and Section SS2 Site 1 and is representative of degraded coastal shrubland on Hog Bay Road south-east of American River Road.
Fauna Assessment Results Birds Forty one native and two introduced bird species were observed within habitats along the proposed pipeline route. Table 5 lists the species observed, along with notes on abundance and habitat preference. Three species of state conservation significance were observed, the state Vulnerable Yellow-tailed Black Cockatoo (Zanda funerea whiteae), and the state Rare Shy Heathwren (Calamanthus cautus halmaturinus) and state Rare Scarlet Robin (Petroica boodang boodang). The number of species at sites ranged from 17 to 22. Mammals
Page 46 of 77
Signs, traces or live sightings were made of five mammal species (Table 6), including the nationally Endangered Kangaroo Island Echidna (Tachyglossus aculeatus multiaculeatus), for which there were numerous traces in areas where larger patches of Eucalyptus cneorifolia Woodland were present (Habitat Class 2). There were also scats observed that were attributed to the state Rare Common Brushtail Possum (Trichosurus vulpecula) in Habitat Class 3. There were no signs of the nationally Endangered Southern Brown Bandicoot (Isoodon obesulus obesulus), and although it considered that the species may be present in areas where large patches of vegetation are adjacent, it is considered that there is only likely to be a negligible or transient population in areas to be impacted by the pipeline. Reptiles There was little reptile activity at the time of inspection. One dead snake was found on the roadside, considered likely to be a Pygmy Copperhead (Austrelaps labialis). Burrows were observed in good condition sections of mallee (Habitat Class 3), which were attributed to one of the two species of Liopholis skink (Liopholis multiscutata, Liopholis whitii), and the Heath Goanna (Varanus rosenbergi), which is considered Vulnerable at state level (Table 7). No other reptile species of state or national conservation significance are considered likely to be present in the site. Other habitat attributes present along the route Figure 4 shows the location of all termite mounds observed during field inspection. Termite mounds are an important habitat attribute, as they may be used as nest sites by the state Vulnerable Heath Goanna (Varanus rosenbergi), as well as a potential food source for the nationally Endangered Kangaroo Island Echidna (Tachyglossus aculeatus multiaculeatus). Most termite mounds were found in association with mallee vegetation to the west of the Island Beach turnoff (Figure 4). Most termite mounds were more than 2 metres from the road verge. Figure 5 shows specific locations of other signs along the proposed alignment. Whilst there were small cracks and crevices in many trees, there were few hollows present. There were no large hollows observed, and only two trees with moderate sized hollows (4-10cm in size) within 2-5 metres of the road verge, in sections of Narrow-leaved mallee in the northern sections of the proposed route. There were three burrow systems attributed to Bush Rats (Rattus fuscipes), and one burrow attributed to a Heath Monitor (Varanus rosenbergi) in the section of good condition mallee between Island Beach and Baudin Beach. These were all between 2-5 metres from the road verge, and were on the dirt track north of the main Hog Bay Road rather than the road itself.

Fauna Assessment Conclusions Habitat Class 1. Exotic Grassland with Sparse Shrubs No specific sensitivities were noted in this association. Habitat Class 2. Kangaroo Island Narrow-leaved Mallee (Eucalyptus cneorifolia) Woodland State Rare Scarlet Robin (Petroica boodang boodang) and state Vulnerable Yellow-tailed Black Cockatoo (Zanda (Calyptorhynchus) funerea whiteae) were observed in this area, but it is unlikely to be impacted by proposed activities. Scratchings from the Nationally Endangered Kangaroo Island Echidna (Tachyglossus aculeatus multiaculeatus) were observed in some areas. This species may fall into pits and trenches associated with this project. Habitat Class 3. Eucalyptus diversifolia and E. rugosa Mallee This diverse community supported a number of species of conservation significance, including the State Vulnerable Heath Goanna (Varanus rosenbergi), the state Rare Common Brushtail Possum (Trichosurus vulpecula), and the nationally Endangered Kangaroo Island Echidna (Tachyglossus aculeatus multiaculeatus). This community is also likely to provide habitat for the State Rare Scarlet Robin (Petroica boodang boodang) and state Rare Shy Heathwren (Calamanthus (Hylacola) cautus halmaturinus). Specific sensitivities would be the presence of termite mounds on the south side of the main road within 2 metres of the road verge, which may be important for nesting for the Heath Goanna. The Nationally Endangered Kangaroo Island Echidna (Tachyglossus aculeatus multiaculeatus) may potentially fall into pits and trenches associated with this project.
Page 53 of 77
Habitat Class 4. Closed coastal shrubland with emergent Eucalyptus rugosa and E. diversifolia State Rare Shy Heathwren (Calamanthus (Hylacola) cautus halmaturinus) observed in this area, and potential habitat for the State Rare Scarlet Robin (Petroica boodang boodang). Neither species is likely to be impacted by works associated with this project. Habitat Class 5. Open coastal shrubland State Rare Shy Heathwren (Calamanthus (Hylacola) cautus halmaturinus) observed in denser patches of shrubland. It is to be significantly impacted by works associated with this project.
Page 54 of 77
4.3 Cumulative impact All of the required vegetation clearance for the construction of the pipeline has been accounted for in the proposed clearance area, including temporary damage to vegetation associated with vehicle movement. Future works to enhance water supply and security that are facilitated by this project are: • works to increase the capacity of the Penneshaw desalination plant including a second desalination plant, upgrades to the pipeline between the EBS at Charing Cross Road and the sea water intake at Desal Drive • a pipeline to supply water to the township of American River. The pipeline proposal is independently viable and does not depend on the future implementation of these projects. 4.4 Address the Mitigation Hierarchy
a) Avoidance – outline measures taken to avoid clearance of native vegetation The pipeline route has been planned to avoid impacts on native vegetation as far as possible within the constraints of cost and practicality. Vegetation clearance has been avoided over 27.1 km (55% of the route) by locating the pipeline away from roadside vegetation in the road verge, the road shoulder or the road bed (Table 8).
Table 8. Extent of clearance width along route Clearance Width Linear Distance Native vegetation is absent 0.575 km Native vegetation is present but clearance is 35.405 km avoided 0.5 m 3.048 km 1.0 to 2.5 m 9.654 km 3.0 to 3.5 m 0.303 km 21 m 0.100 km Total Route 49.085 km
Vegetation impacts will be avoided by locating storage and laydown sites in areas of non-native vegetation (Haby and Rowley 2020b). The excavation of the pipeline trench is a risk to native fauna. Kangaroo Island Echidna, Tiger Snake and Heath Goanna may fall into trenches and have difficulty exiting. This hazard will be avoided by : • refilling trenches soon after excavation; • fencing and/or providing exit ramps in unattended trenches; and • conducting an early morning search and removing fauna in any trenches left open overnight.
b) Minimization – if clearance cannot be avoided, outline measures taken to minimize the extent, duration and intensity of impacts of the clearance on biodiversity to the fullest possible extent (whether the impact is direct, indirect or cumulative). Vegetation data was collected to support a risk-based approach to balance engineering requirements with conservation aspects. Conservation values of the route were mapped in sections with a resolution of less than 20 m. The sections were determined by: • the cleared space available between the edge of the bitumen and the start of the roadside vegetation • the vegetation association present • threatened plant species present • vegetation and fauna habitat condition
Page 55 of 77
This data was used to prioritise roadside segments for protection (Table 9) and minimise impacts to conservation values.

Vegetation had the highest priority for protection along 11.513 km of the route because it supported a critically endangered ecological community and endangered flora species under the EPBC Act (Table 10). Impacts to this vegetation has been avoided. Impacts to Priority 2 and 3 vegetation have been minimised and limited to 0.107 and 0.158 ha, respectively.

Vegetation along the route includes high threat weeds including Bulbil Watsonia, Bridal Creeper, Bridal Veil, Aleppo Pine and Freesia. The risk of spreading these weeds can be minimised by avoiding vegetation disturbance where these weeds are prevalent and disposing of cut plant material safely off-site.
c) Rehabilitation or restoration – outline measures taken to rehabilitate ecosystems that have been degraded, and to restore ecosystems that have been degraded, or destroyed by the impact of clearance that cannot be avoided or further minimized, such as allowing for the re-establishment of the vegetation.
Vegetation impacts rehabilitated by: • Stockpiling and replacing topsoil on the excavated trench when working in the road verge. • Stockpiling and replacing cut native vegetation in areas disturbed by pipeline construction.
d) Offset – any adverse impact on native vegetation that cannot be avoided or further minimized should be offset by the achievement of a significant environmental benefit that outweighs that impact.
Page 56 of 77
The NVC will only consider an offset once avoidance, minimization and restoration have been documented and fulfilled. The SEB Policy explains the biodiversity offsetting principles that must be met. TO BE DETERMINED
4.5 Principles of Clearance (Schedule 1, Native Vegetation Act 1991) The Native Vegetation Council will consider Principles 1(b), 1(c) and 1(d) when assigning a level of Risk under Regulation 16 of the Native Vegetation Regulations. The Native Vegetation Council will consider all the Principles of clearance of the Act as relevant, when considering an application referred under the Planning, Development and Infrastructure Act 2016.

Moderating factors that may be considered by the NVC The clearance is not expected to have a significant impact on the species. The clearance is generally less than 2.5 m wide and has a maximum of 3.5 m on the edge of the roadside vegetation facing the carriageway (except GG1 Site 2) (Table 8). In general the roadside vegetation supporting the threatened species is more than 20 m. Clearance is not expected to significantly reduce the extent or quality of habitat or to lead to a decline in the species. Clearance at GG1 Site 2 is more extensive and impacts 0.21 ha. However the state of the affected species is 'rare' and the clearance is not extensive enough to have a significant impact on them.

Moderating factors that may be considered by the NVC Impact Significance The clearance is of a small extent and is not likely to have a significant impact on the threatened plant community in terms of its condition, extent, continuity or capacity to recover. At GG2 Site 2 it is proposed to clear 190 m2 from the vegetation edge facing the carriageway over a total section length of 287.6 m. At XX1 Site 2 it is proposed to clear 40 m2 from the vegetation edge facing the carriageway over a total section length of 26.8 m. At VV Site 1 it is proposed to clear 16.2 m2 from the vegetation edge facing the carriageway over a total section length of 16.2 m. At QQ Site 2 it is proposed to clear 235 m2 from the vegetation edge facing the carriageway over a total section length of 470 m. At PP Site 3 it is proposed 59 m2 from the vegetation edge facing the carriageway over a total section length of 117 m. Area of Impact The clearance in each community is less than 1% of the area of the that community within the immediate vicinity. Condition and Integrity of Affected Vegetation The affected vegetation is in good condition with an intact overstorey and diverse understorey that is also structurally intact. Principle 1e - Relevant information it is Cygnet IBRA Association remnancy - 27% significant as Total Biodiversity Score 20.69 a remnant of vegetation in Amberley IBRA Association remnancy - 21% an area which Total Biodiversity Score 13.61 has been extensively Gantheaume IBRA Association remnancy - 88% cleared.

Vegetation remnancy is relatively high in the central part of the route in the steep limestone dunefields of the Gantheaume IBRA Association. Vegetation has been cleared most extensively in the western (Cygnet, Amberley) and eastern (Coranda) parts of the route. Roadside vegetation is an important component of the remaining vegetation.
The affected Kangaroo-Island Narrow-leaved Mallee Woodland is located in the Cygnet, Amberley and Coranda IBRA Associations.
Page 66 of 77
The section of the route along Hog Bay Road between Arronmore Road and American River Road is particularly significant as a remnant because the roadside vegetation supports several endangered and threatened plant species. The roadside vegetation is an important habitat for these plants (Taylor, 2008).
Vegetation is in good health with good prospects for remaining intact where the roadside vegetation is intact and continuous with broader remnants across the landscape. This is the case: • between Arronmore Road and Red Banks Road • between American River Road and Muston Road • between Island Beach and Baudin Beach and • at the top of the scarp at Kangaroo Head near Franks Road. Despite its isolation from larger remnants, the roadside vegetation has good spatial integrity. Roadside vegetation on Hog Bay Road is largely continuous and intact in a broad corridor approximately 20 m for most of the route between: • between Min Oil Road and American River Road • in the limestone dunes south of Pelican Lagoon and • between Island Beach and Baudin Beach. Roadside vegetation is relatively fragmented and vulnerable to invasion by weeds: • east of the airport • in the salt marsh near Nepean Bay • immediately south-east of the American River intersection • at the western end of the route at Pelican Lagoon and • at American Beach.

6. Significant Environmental Benefit
A Significant Environmental Benefit (SEB) is required for approval to clear under Division 5 of the Native Vegetation Regulations 2017. The NVC must be satisfied that as a result of the loss of vegetation from the clearance that an SEB will result in a positive impact on the environment that is over and above the negative impact of the clearance.
ACHIEVING AN SEB Indicate how the SEB will be achieved by ticking the appropriate box and providing the associated information:
Establish a new SEB Area on land owned by the proponent. Provide information below.
Use SEB Credit that the proponent has established. Provide the SEB Credit Ref. No. ______
Apply to have SEB Credit assigned from another person or body. The application form needs to be submitted with this Data Report.
Apply to have an SEB to be delivered by a Third Party. The application form needs to be submitted with this Data Report.
X Pay into the Native Vegetation Fund. SA Water will provide payment to the fund as directed by the NVC.
PAYMENT SEB If a proponent proposes to achieve the SEB by paying into the Native Vegetation Fund, summary information must be provided on the amount required to be paid and the manner of payment: • Payment amount required (including admin. fee) • If the proponent wishes to make the payment in stages, details of those stages, including clear dates or milestones in which payments will be made. Noting, for staged payments, payments must be received prior to clearance occurring, therefore staged payments are only suitable for projects where the clearance will occur in a staged manner.
SA Water will provide payment to the fund as directed by the NVC.
