NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

2.0 BACKGROUND 2.1 Purpose SA Water are proposing to build a new sea water desalination plant in Penneshaw and supporting infrastructure to the existing Middle River – Kingscote network via a new trunk main.

The new trunk main pipeline is expected to be constructed primarily along Hog Bay Road, from Penneshaw Desalination Plant to the corner of Arranmore Road, Cygnet River to provide a secure water supply for Kangaroo Island.

This application is for Stage 2 of the pipeline from the 3373 Hog Bay Road to the Penneshaw Desalination Plant.

2.2 Background In 2018, SA Water released the Kangaroo Island long-term water security plan (the Plan).

The plan was developed in consultation with key stakeholders, including local government, industry, environment, and community groups and outlined a framework that will ensure increases in water demand for Kangaroo Island will be met for the next 25 years.

The Plan sought to balance challenges and opportunities across a range of factors, both now and into the future. It was designed to ensure a safe, secure and reliable water supply for current and future customers while keeping prices as low and stable as possible for SA Water customers across the state.

A number of options to ensure water security were considered during the development of the Plan. The plan identified that an additional desalination plant was the preferred option to provide this water security.

Although the existing Middle River and Penneshaw water supply networks have adequate capacity to meet current needs and sustain organic growth until around 2036, the recent bushfires, along with a very hot and dry summer, has seen an increase in demand placing stress on the Middle River reservoir.

Experience during these bushfires showed that demand during these events significantly increases. This placed additional demand on the Island’s water resource.

SA Water are now accelerating the recommendation of the Plan to construct a new desalination plant at Penneshaw along with a new pipeline and associated infrastructure that will connect to the existing Middle River-Kingscote water supply network.

KI Pipeline Stage 1 will be established between the corner of Arranmore Road and Playford Highway and 3373 Hog Bay Road near Pelican Lagoon, Figure 1

Botanical KI Pipeline Stage 2 Page 6 of 56 Enigmerase

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

Figure 1- Stage 1 KI Pipeline

On 27 March 2019 KI Pipeline Stage 1 was approved, subject to conditions, by Native Vegetation Council for Native Vegetation Clearance, Decision Notification NVR2019/3016/520. On 9 September 2019 the Native Vegetation Construction Environmental Management Plan for KI Pipeline Stage 1 was approved by the Native Vegetation Council.

The proposed Native Vegetation Construction Environmental Management Plan, Attachment 1, has been updated to incorporate this clearance assessment for Stage 2 and any proposed variations to Stage 1.

2.3 Location Stage 2 of the proposed pipeline will be established between 3373 Hog Bay Road to the Penneshaw Desalination Plant, Figure 2.

Botanical KI Pipeline Stage 2 Page 7 of 56 Enigmerase

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

Figure 2- Stage 2 KI Pipeline

Generally the pipeline will be established on the “south side” of Hog Bay Road, however detailed design of the pipeline's location in the road reserve has not yet been undertaken. The alignment may in places need to be within a lane of the road or cross from one side to the other in order to minimise native vegetation clearance and other environmental impacts such as crossings of watercourses. Construction, hydraulic and connection requirements including interface with other services will also impact the alignment.

DPTI have established a number of significant sites, Figure 3, along the proposed pipeline route. DPTI provide general advice on the management of these sites within the road verge which includes reduced cross drain maintenance, minimised spraying and slashing outside the white post. In all cases the road envelope is maintained in accordance with DPTI standards, Figure 5.

Figure 3- DPTI Significant Sites

Ecological Associates undertook a preliminary flora and fauna assessment of the proposed Stage 2 pipeline route. This detailed vegetation assessment for the clearance application is relatively consistent with the preliminary assessment and expands as follows- • Each native vegetation community has been classified in accordance with the Kangaroo Island Floristic Mapping developed by the Department for Environment and Water (DEW); • Each Kangaroo Island Narrow-leaved Mallee community has been assessed against the criteria within the Conservation Advice for Kangaroo Island Narrow-leaved Mallee (Eucalyptus cneorifolia) Woodland under the EPBC Act 1999; • The Tecticornia arbuscula shrubland community is 3.5m on the vegetation side of the white post and as such outside the SA Water clearance zone and work zone; • The detailed assessment showed that the native vegetation within each community is consistent on both sides of the road and as such the impacts, or otherwise, will be equivalent; • Fauna observations have been included in the Bushland Assessment spreadsheets; and • Recommendations for the management of fauna have been included in the proposed Native Vegetation Construction Environmental Management Plan where appropriate.

The proposed Native Vegetation Construction Environmental Management Plan, Attachment 1, describes the construction methodology in detail.

2.4 Approvals The following approvals are required for KI pipeline Stage 2-

Botanical KI Pipeline Stage 2 Page 9 of 56 Enigmerase

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

Native Vegetation Council • Variation to the Native Vegetation Clearance approval for Stage 1; • Native Vegetation Clearance for Stage 2; and • Proposed Native Vegetation Construction Environmental Management Plan.

In line with SA Water requirements the Significant Environmental Benefit, if required, will be based on actual clearance undertaken. As a result this Native Vegetation Assessment provides a “worst case scenario”

KI Landscape Board • Water Affecting Activity Permit.

This Native Vegetation Clearance Assessment incorporates the general requirements of a potential Water Affecting Activity Permit and any native vegetation clearance required around water courses. A total of 8 water crossing have been identified along the KI Pipeline Stage 2 route. KI Landscape Board have identified one water crossing of concern being Deep Creek near Baudin Beach, which is a deep culvert where an alternative construction option will be utilised.

Kangaroo Island Council: • SA Water will apply to KI Council to install a pipeline in the road reserve under the Water Resources Act.

DPTI: • General pipeline alignment within the road reserve and treatments to road infrastructure; • SA Water will apply to DPTI to install a pipeline in the road reserve under the Water Resources Act.

3.0 METHOD 3.1 Flora Assessment The flora assessment of the proposed KI Pipeline Stage 2 route was designed to identify any significant areas along the pipline route that may impact on the project. As a result the survey area was much larger than the proposed clearance areas to ensure all issues were identified prior to the commencement of construction.

For ease of survey, and in line with other roadside surveys undertaken on Kangaroo Island, the proposed route of the pipline stage 2 was divided into 8 Segments, Table 1. Note, Approximately 1km of Segment SS2 is located within the KI Pipeline Stage 2 survey area, the remainder is located with KI Pipeline Stage 1.

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

The flora along the proposed route was assessed using standard roadside survey methodology adopted by DEW on Kangaroo Island as follows. For each Segment- • The pipeline route was walked with the primary focus of surveying flora within 10m of the white post; • Native vegetation communities were identified with the start and end location of each community recorded with a hand-held GPS to an accuracy of <5m; • A complete species list of all native and introduced plant species was produced for each identified vegetation community; • Nationally Threatened, State Listed or Regionally Significant plant species populations were identified and their location recorded with a hand-held GPS to an accuracy of <5m; • Presence of the Kangaroo Island Narrow-leaved Mallee Woodland Ecological Community was identified and recorded with a hand-held GPS to an accuracy of <5m; • Proclaimed introduced plant species populations were identified and their location recorded with a hand-held GPS to an accuracy of <5m; and • Survey data relating to records of Nationally Threatened, State Listed or Regionally Significant plant species was recorded following BDBSA Minimum Data Standards and provided to BDBSA for uploading.

Both sides of the road carriageway were surveyed to establish a comprehensive understanding of each vegetation community. This allows for the pipline to be established on either side of the road depending on construction constraints. The native vegetation is consistent on both side of the road and as a result determined to be the same vegetation community.

Appendix 2 contains the recorded flora for each segment and Appendix 3 provides the introduced flora recorded for each segment.

3.2 Fauna Assessment The potential fauna to occur along the pipeline route was determined utilising the following- 1. Fauna recorded within 5km of each segment from on-line databases; 2. Observations of fauna including tracks and traces while undertaking the flora assessment; and 3. Fauna observed by Ecological Associates.

Marine fauna were removed from the above comprehensive list and then the remaining fauna status was assessed utilising Gillam, S. and Urban, R. (2014) to reduce the list to Nationally Threatened and State Listed fauna which is summarised in Appendix 4.

The significant fauna list from above was then added to the Bushland Assessment Spreadsheets.

In line with the application process undertaken for KI Pipeline Stage 1 a detailed fauna survey of the clearance areas is very unlikely to provide any further information as the clearance is adjacent to a major road. The works are also unlikely to impact on the fauna any more than the major road.

Appendix 1 provides a photograph of each site.

4.1.3 Proposed Impact The preferred alignment by both SA Water and DPTI for the pipeline is on the vegetation side of the white post. This however does not prevent the pipeline going closer, or within, the existing roadway if other constraints require it and DPTI agreement can be obtained regarding road reinstatement.

DPTI maintenance standards for contractors undertaking roadside vegetation maintenance require a 3m clearance of woody species (<150mm or <100mm for multi stem plants) on the vegetation side of the white post and 1m for mowing and spraying, Figure 5. Where Roadside Significant Sites, Figure 3, and environmentally sensitive areas are present clearance of pre-existing woody species may be reduced to 1m from the white post. DPTI overhead clearance is 5.5m above the lane and extends 3m over the shoulder.

Botanical KI Pipeline Stage 2 Page 14 of 56 Enigmerase

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

Figure 5- DPTI Maintenance Clearance Standard (M14 Section 5)

As part of the SA Water Concept Design, one constructability meeting was held with input from a civil contractor, from which a proposed construction methodology was developed with the intention of minimising cost as well as impact on native vegetation. The pipe diameter is anticipated to be 375mm which requires a trench of approximately 1m width and 1.7m depth for installation. This is likely to require an excavator or trenching machine to straddle the trench for excavation requiring a total footprint width of approximately 2.9m and height of 3.7m.

The preliminary alignment options will be built upon in the “ECI” or “D&C” detailed design phase of the project when actual costs can be applied and the offset for clearance balanced.

Alignment Option 1, preferred option, places the pipe alignment 1m from the edge of the bitumen, Figure 6. This has several advantages including a faster laying rate, no need for bitumen disposal or reinstatement and reduces the impact on passing traffic by other support equipment. It is also safer for SA Water Operational staff to undertake maintenance activities during operation as all valves and fire plugs are located off the road.

Figure 6- Alignment Option 1 (Preferred)

Botanical KI Pipeline Stage 2 Page 15 of 56 Enigmerase

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

Alignment Option 1 will require a clearance of 3.5m from the edge of the bitumen to a height of 3.7m. As a result all clearance, other than woody species with a diameter of >150mm, or >100mm for multi stem plants, will be within the DPTI maintenance clearance envelope.

Alignment Option 2, Figure 7, places the pipe alignment in the verge adjacent to the bitumen. This option requires a greater level of reinstatement and construction difficulty due to the proximity to the road carriageway ensuring the integrity of the road carriageway is maintained. Option 2 will however require less vegetation clearance.

Figure 7- Alignment Option 2

Alignment Option 2 will require a clearance of 2.5m from the edge of the bitumen to a height of 3.7m. As a result all clearance, other than woody species with a diameter of >150mm, or >100mm for multi stem plants, will be within the DPTI maintenance clearance envelope.

Alignment Option 3, Figure 8, places the pipe alignment in the centre of the bitumen lane. This option requires no vegetation clearance, but has large reinstatement requirements and it is also more difficult to manage the work zone.

Figure 8- Alignment Option 3

Botanical KI Pipeline Stage 2 Page 16 of 56 Enigmerase

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

SA Water may also move the alignment to the opposite side of the road if further obstacles occur. If this occurs the impacts on the native vegetation will be equivalent irrespective of which alignment option is adopted.

SA Water are also undertaking tree assessments of woody species with a diameter of >150mm, or >100mm for multi stem plants, to determine the impacts on the root zones. Where the preferred alignment will impact on the Structural Root Zone (SRZ) and/or have a greater than 20% incursion into the Tree Protection Zone (TPZ) an alternative alignment maybe utilised when there are multiple trees with overlapping structural root zones present.

As the Hog Bay Road is compacted and sealed there is less moisture available under the road surface, which should mean it is less attractive for the roots of adjacent vegetation. However, if there are large trees adjacent this can impact on their root zones, and may also require trimming of overhanging branches. Where there are only one or two large trees present, this impact can be reduced by using techniques like digging carefully within the structural root zone and bridging any large roots encountered as you would other services, and further exploratory work (e.g. potholing) may be recommended prior to detailed design to determine the nature and extent of roots present in the tree protection zone.

Tree Assessments were undertaken on 9, 16 and 23 June 2020, Attachment 2.

The Concept Design alignment developed by SA Water took into account vegetation, physical and constructability constraints, Table 3. 1 Pipe Alignment Option 1- 2- 3 2 Significant Subtropical and Temperate All outside impact zone Communities Coastal Saltbush Kangaroo Island Narrow- QQ Site 6 leaved Mallee Woodland 3 Significant Nationally Threatened Flora Nil recorded Species Fauna Managed as part of the construction EMP 4 DPTI Significant Sites Generally about management 5 Tree Assessments Attachment 2 6 Physical 7 Constructability Table 3- Alignment Option Criteria

Detailed survey of the KI Pipeline Stage 2 has shown the white post location to average 1.6m from edge of bitumen. For the purpose of calculating the worst case scenario clearance requirements for the KI Pipeline Stage 2, the white posts are nominally located 1m from the edge of the bitumen.

The distance between the white post and the vegetation was measured on 9 June 2020.

The amount of native vegetation clearance required (with the white post nominally 1m from the edge of the bitumen) is calculated as follows- Required Clearance on the vegetation side of the white post (Option 1- 2.5m, Option 2- 1.5m) minus the average distance between the white post and the vegetation multiplied by the length.

4.2.2 Area of Impact SA Water are seeking a maximum clearance of 0.8069ha for the KI Pipeline Stage 2.

The clearance calculation is based on- • The white post being 1m from the edge of the bitumen however the actual distance averages 1.6m. • The allocated alignment option is a best estimate considering concept design level physical and constructability constraints. As a result the calculation is considered a worst case scenario.

The area of actual clearance will be fully mapped and provided to the Native Vegetation Council as part of the reporting required to establish the actual SEB.

4.2.3 Mitigation Hierarchy Avoidance As a rule, clearance of native vegetation during the construction of the pipeline will be avoided where possible. The Concept Design and future refinement in Detailed Design will be based on the Decision Tree, Figure 10-

Figure 10- Alignment Decision Tree

Botanical KI Pipeline Stage 2 Page 20 of 56 Enigmerase

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

The proposed Native Vegetation Construction Environmental Management Plan details the construction methodology and how native vegetation clearance will be avoided where possible.

As a result of the above, a cleared area of 2.5m on the vegetation side of the white post is all that is required. No clearance will occur where- • The cleared area between the white post and the vegetation is greater than 2.5m; • Where an alternate pathway through the roadside vegetation occurs; and • Pipeline alignment is moved into the road to avoid extensive impacts on multiple structural root zones or due to other constructability issues.

SA Water have investigated seven alternative options for the pipeline route, Figure 11. Table 7 explains why each of the seven alternative route options have been discounted. Alternative 1 • Requires more vegetation clearance than following the Hog Bay Road • Has enormous trees with massive roots meaning impacts on root zone will be great. Alternative 2 • Requires more vegetation clearance than following the Hog Bay Road • Requires building a road access with additional cost and ongoing maintenance • Large tree root zone impacts • Constructability issues • Not very accessible during bushfire Alternative 3 • Requires more vegetation clearance than following the Hog Bay Road • Requires building a road access, in part, with additional cost and ongoing maintenance • Large tree root zone impacts • Not very accessible during bushfire Alternative 4 • Requires an easement over private property that does not follow a boundary Alternative 5 • Requires more vegetation clearance than following the Hog Bay Road • Requires building a road access, in part, with additional cost and ongoing maintenance • Large tree root zone impacts • High elevation impacting on hydraulics • Not very accessible during bushfire Alternative 6 • Requires more vegetation clearance than following the Hog Bay Road • Large tree root zone impacts • Follows SA Power Network easement, would involve conflict with overhead power line and as a result cannot share easement- would require a parallel easement with additional native vegetation impacts • Not very accessible during bushfire Alternative 7 • Requires more vegetation clearance than following the Hog Bay Road • Large tree root zone impacts • Lots of termite mounds • Not very accessible during bushfire Table 7- Alternative Route Options Assessment

Figure 11- Alternative Route Options Assessed

Minimisation The Tree Assessments along the proposed pipeline route have been utilised to determine impacts on the tree vegetation. Where the preferred alignment of the pipeline is to impact on the Structural Root Zone and/or impact on >20% of the Tree Protection Zone the alternative alignment will be utilised or other appropriate measures will be taken to minimise impacts on roots of adjacent large trees as detailed in SA Water's Tree Assessment SOP, Attachment 3.

KI Pipeline Stage 2 includes 8 water crossings of which 7 are culverts and 1 is a deep culvert. KI Landscape Board have identified the deep culvert over Deep Creek as requiring special consideration. It is anticipated no additional native vegetation clearance will be required, other than included in this application, to cross these sites. There are 5 options for water crossings as follows- 1. Trench within road corridor over the stormwater culverts. 2. Trench within road corridor underneath the stormwater culverts. Use non-destructive methods to excavate a void beneath the culverts and backfill the void between pipe and soil with low strength grout. 3. Crossing the waterway to the side of the bridge via trenching through the waterway. Backfill using CLSM to prevent erosion of the waterway and pipe embedment. 4. Trenchless crossing underneath or to the side of the bridge structure. This option is not preferred due to its high cost, and that there are no trenchless contractors located on Kangaroo Island.

Botanical KI Pipeline Stage 2 Page 22 of 56 Enigmerase

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

5. Above ground MSCL pipework located on the downstream side of the bridge structure. Avoid attaching the pipe to the bridge if possible. This option is not preferred due to the high cost, potential for damage to the pipe in the future, and thermal impacts on the pipeline.

In general, the impact to fauna and fauna habitat is unlikely to be significant as the pipeline will be installed in the road / road verge. Ground dwelling animals (including the KI Echidna and Heath Goanna) may also fall in to trenches and pits associated with construction works. To mitigate impacts, any open trenches and pits left overnight that are associated with construction works will be covered if possible or provide with some way for fauna to escape (e.g earth ramp), and checked in the morning for any fauna that may have fallen in prior to works commencing.

The Heath Goanna may lay their eggs in termite mounds that are present in these areas, with several termite mounds observed adjacent to the road. Termite nests that may be affected by the trenching works will be checked for the presence of Heath Goanna nests by a fauna expert prior to works commencing, who will advise whether the nest can be avoided or relocated. This will be managed as construction proceeds.

The proposed Native Vegetation Construction Environmental Management Plan details the construction methodology, how native vegetation clearance will be minimised and how wildlife impacts will be minimised.

Rehabilitation and Restoration The pipeline is required to be installed in accordance with SA Water Specifications. These specifications stipulate how the pipe must be backfilled within the trench. These specifications allow for some of the original material to be returned. This also reduces material being taken off-site.

The reinstatement of the pipeline trench will include placing the excavated top soil back on top of the trench. The top soil will be excavated and placed on the road (as described above) and then returned to the trench after a minimum amount of time. The trench will be closed each night.

Mulched vegetation will be placed over the trench, following reinstatement, where possible and the vegetation will be left in a state that reflects good road verge management, similar to what is achieved along Hog Bay Road by DPTI.

Reinstatement requirements included with any Water Affecting Activity Permit will be strictly adhered to.

The proposed Native Vegetation Construction Environmental Management Plan details the construction methodology, the management of trimmed vegetation and site reinstatement.

Offset The Offset will be calculated based on actual clearance undertaken.

4.3 Section 28 of the Native Vegetation Act 1991 If the clearance for the KI Pipeline Stage 2 does not meet the criteria of the Native Vegetation Regulations 2017, then the clearance must be considered under Section 28 of the Native Vegetation Act 1991.

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

4.3.1 Substantially Intact Stratum A stratum of native vegetation is considered Substantially Intact if- a) the stratum has not been seriously degraded by human activity during the immediately preceding period of 20 years; or b) the only serious degradation of the stratum by human activity during that period has been caused by fire.

To determine if Substantially Intact Stratum exists the following questions are considered. Does the native vegetation constitute a continuous stratum? Each of the following must be satisfied 1a The plants within the stratum of interest are growing at original (pre-European) density for that community; and 1b Contains a diversity of species similar to original (pre-European) vegetation of that community; and 1c Is part of a contiguous area of vegetation consisting of the stratum, including on adjacent properties, that is at least one hectare in area and for linear patches, generally greater than 30 m in width. Small, isolated or linear patches of vegetation are subject to significant edge affect and likely to degrade over time; and 1d Does not contain introduced perennial species occupying greater than 20% cover within that stratum. AND Has the vegetation been subject to degradation within the past 20 years? The following must be satisfied 2a Any degradation must have been undertaken in compliance with the Native Vegetation Act 1991; and 2b Must have occurred within the past 20 years from the date of application; and 2c Must be a direct result of human activity; and 2d May include the following: • Fragmentation of the area of vegetation • Modifying, destroying or removing vegetation cover or plant species diversity • Changing abiotic (non-living) factors such as water, nutrients or soil which subsequently impacts on native vegetation. This may include, but not limited to altered hydrology, compaction of soil or increased soil nutrient levels; and 2e Does not include degradation as a result of fire. To be considered Substantially Intact Stratum the clearance area MUST- • Meet all the criteria of question 1 (Continuous Yes); and • Meet none of the criteria of question 2 (Degradation No).

Wetland- Principle f The definition of a wetland, for the purpose of this principle is- • land permanently or temporarily underwater or waterlogged that must have surface water or waterlogging of sufficient frequency and/or duration to effect the biota; and/or • if the area is defined on 1:50,000 series topographic map as either a perennial or intermittent lake or land subject to inundation.

No sites are considered to be a wetland.

Amenity- Principle g The Amenity Principle is assessed utilising the following criteria. Location of the trees 1 • e.g. near a township, adjacent to a main road or tourist route 2 Cultural or historical values and local community views Number and distribution of trees to be cleared 3 • how many trees will be retained? • would removal of the trees change the landscape character? Species and size of trees 4 • large trees generally more impressive landscape quality • red gums, because of their size, are often considered of high landscape value Condition and shape 5 • trees suffering extensively from dieback are not generally aesthetically pleasing • well-shaped trees may be considered of greater landscape quality.

Table 17 assesses the amenity value of the proposed clearance area to determine the variance to the Amenity Principle. Location of Trees Subject to alignment Option 1, 2 and 3 Cultural Value The “avenue” of trees over the road will be maintained Number and Distribution Up to a 2.5m strip will be removed as a worst-case scenario Species and size As described in this report Condition Good quality vegetation and species diversity Variance to Principle Not Table 17- Amenity Assessment

6.0 EPBC ACT

Environment Protection and Biodiversity Conservation (EPBC) Act 1999 is Commonwealth legislation that protects national environmental matters. Actions that have, or are likely to have, a “significant impact” on a matter of national environmental significance require approval from the Australian Government Minister for the Environment.

6.1 Threatened Ecological Communities Kangaroo Island has 2 listed nationally threatened ecological communities.

A small patch of Subtropical and Temperate Coastal Saltbush occurs near Davies Road. This community is however 4.5m from the road edge and as a result will not be impacted by the proposed pipeline alignment.

The Kangaroo Island Narrow-leaved Mallee Woodland Ecological Community was recorded during the Bushland Assessment. The Conservation Advice for Kangaroo Island Narrow-leaved Mallee (Eucalyptus cneorifolia) Woodland under the EPBC Act 1999 states the minimum condition of a patch, for the purposes of considering any potentially significant detrimental actions to the ecological community. A patch of roadside vegetation, including native vegetation on the neighbouring properties, is protected under the EPBC Act as the Kangaroo Island Narrow-leaved Mallee Woodland Ecological Community if the following criteria are met- 1. Kangaroo Island Narrow-leaved Mallee is the dominant or co-dominant species where a mature tree canopy occurs. Other species may be present in the tree canopy, as described in the canopy layer description, above, but are never dominant on their own. The tree canopy cover reaches up to 60-100% in long unburnt sites; and 2. a. At that point, the shortest cross-sectional mature canopy width of the vegetation is 60 metres or more. Mature canopy width is measured from canopy edge to canopy edge, ignoring canopy breaks within the vegetation of up to 20 metres. This means that strips of the ecological community along each side of a road can effectively be treated as part of a single area of vegetation where the width of the roadside break is 20 metres or less; or b. Where two separate areas of the ecological community at least 60 metres wide are connected by a narrow section of the ecological community, e.g. a strip along only one side of the road, the narrow section is included in the patch if it is more than five metres wide and less than 500 metres long (i.e. the separation between the two wide areas is less than 500 metres).

The Kangaroo Island Narrow-leaved Mallee Woodland Ecological Community is considered of High Quality if the following criteria are also met- 3. The total continuous area of the ecological community is one hectare or more; and 4. The cover of non-indigenous plant species in the understorey layers is less than 50% of the total perennial cover of the understorey layers; and 5. Four or more native plant species are present above-ground in the understorey layers across the patch.

Three sites along the survey route were identified as Kangaroo Island Narrow-leaved Mallee communities as part of the Bushland Assessment. One of these sites was determined to meet the Kangaroo Island Narrow-leaved Mallee Woodland Ecological Community criteria.

Figure 13 shows the location of the Kangaroo Island Narrow-leaved Mallee Woodland Ecological Community.

6.1.1 Significant Impact Assessment The Significant Impact Guidelines under the EPBC Act 1999 provide the Significant Impact Criteria for Critically Endangered and Endangered Ecological Communities as follows- An action is likely to have a significant impact on a critically endangered or endangered ecological community if there is a real chance or possibility that it will: • reduce the extent of an ecological community; • fragment or increase fragmentation of an ecological community, for example by clearing vegetation for roads or transmission lines; • adversely affect habitat critical to the survival of an ecological community; • modify or destroy abiotic (non-living) factors (such as water, nutrients, or soil) necessary for an ecological community’s survival, including reduction of groundwater levels, or substantial alteration of surface water drainage patterns; • cause a substantial change in the species composition of an occurrence of an ecological community, including causing a decline or loss of functionally important species, for example through regular burning or flora or fauna harvesting;

Botanical KI Pipeline Stage 2 Page 38 of 56 Enigmerase

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

• cause a substantial reduction in the quality or integrity of an occurrence of an ecological community, including, but not limited to: o assisting invasive species, that are harmful to the listed ecological community, to become established, or; o causing regular mobilisation of fertilisers, herbicides or other chemicals or pollutants into the ecological community which kill or inhibit the growth of species in the ecological community, or; • interfere with the recovery of an ecological community.

The relevant Significant Impact Guidelines in relation to Local Government also states- • Routine vegetation management to maintain existing roads in or adjacent to a World Heritage property, a National Heritage place, a Ramsar wetland or a listed threatened species or ecological community would not normally be expected to have a significant impact on a matter of national environmental significance. • A proposed new road through a World Heritage property, a National Heritage place, or a Ramsar wetland or a road that would require clearing of native vegetation that contains nationally listed threatened species or ecological communities is likely to be significant under the EPBC Act and should be referred to the minister. It will also be necessary to consider the environment of the Great Barrier Reef Marine Park if the proposed new road occurs immediately adjacent to the Great Barrier Reef Marine Park. • Where road verge maintenance is carried out regularly (for example, every one or two years) it would not be expected to have a significant impact on a critically endangered or endangered plant species. On the other hand, if a population of a critically endangered or endangered plant species becomes established on a road verge (because the verge has not been graded or weeded for a number of years), then clearing that road verge is likely to have a significant impact on a matter of national environmental significance. • Widening an existing road would not normally be expected to be significant under the EPBC Act where the road verge has previously been cleared or the vegetation beside the road has been heavily modified. However, if road widening would require removal of native vegetation that contains critically endangered or endangered plant species or ecological communities, it is likely to have a significant impact and should be referred to the minister.

As discussed throughout this report the proposed clearance for the proposed KI Pipeline Stage 2 will consist of the following- • Avoidance of clearance and significant species will occur where possible; • Maximum of 3.5m clearance from the edge of the bitumen; • Primarily vegetation trimming will occur; • No clearance beyond 3.5m from the edge of the bitumen; • Full reinstatement and tidy up will occur at the end of each day; • Clearance will “look” like verge management when complete; • Alignment will be where the Tree Assessments show little impact on the Structural Root Zone and/or >20% incursion into the Tree Protection Zone of multiple trees and where other mitigation options are not viable; and • Works will be undertaken in accordance with the proposed Native Vegetation Construction Environmental Management Plan.

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

The proposed installation of the KI Pipeline Stage 2 should not have a significant impact on the Kangaroo Island Narrow-leaved Mallee Woodland however SA Water have chosen to prepare an EPBC Act referral.

6.2 Threatened Plant Species Kangaroo Island has 18 listed nationally threatened plant species. Zero Nationally Threatened flora species were recorded along the proposed pipeline Stage 2 route.

6.3 Threatened Fauna Species Kangaroo Island has 14 listed nationally threatened terrestrial (excluding marine) fauna species. Eight nationally threatened terrestrial fauna species have been recorded with 5km of the site of the proposed KI Pipeline Stage 2, Table 22.

6.3.1 Significant Impact Assessment The Significant Impact Guidelines under the EPBC Act 1999 provide the Significant Impact Criteria for Critically Endangered and Endangered Species as follows- An action is likely to have a significant impact on a critically endangered or endangered species if there is a real chance or possibility that it will: • lead to a long-term decrease in the size of a population; • reduce the area of occupancy of the species; • fragment an existing population into two or more populations; • adversely affect habitat critical to the survival of a species; • disrupt the breeding cycle of a population; • modify, destroy, remove, isolate or decrease the availability or quality of habitat to the extent that the species is likely to decline; • result in invasive species that are harmful to a critically endangered or endangered species becoming established in the endangered or critically endangered species’ habitat • introduce disease that may cause the species to decline; or • interfere with the recovery of the species.

The relevant Significant Impact Guidelines in relation to Local Government, are provided in Section 6.1.1.

NATIVE VEGETATION CLEARANCE ASSESSMENT 29 August 2020

As discussed throughout this report the proposed clearance for the proposed KI Pipeline Stage 2 will consist of the following- • Daily and ongoing surveys of the construction zone to ensure fauna are not located within the zone; • Relocate fauna where applicable; • Avoidance of clearance where possible; • Maximum of 3.5m from the edge of the bitumen; • Primarily vegetation trimming will occur; • No clearance beyond 3.5m from the edge of the bitumen; • Works are along a major road; • Full reinstatement and tidy up will occur at the end of each day; • Clearance will “look” like verge management when complete; and • Works will be undertaken in accordance with the Native Vegetation Construction Environmental Management Plan

The proposed installation of the KI Pipeline Stage 2 should not have a significant impact on the Nationally Threatened fauna species recorded near the proposed pipeline route however SA Water have chosen to prepare an EPBC Act referral.
