iii Golden Beach Gas Project: Targeted Flora Surveys – Spring 2020

SUMMARY The proposed Golden Beach Gas Project is currently undergoing the Environment Effects Statement process. To address the onshore biodiversity impacts, a Terrestrial and Freshwater Biodiversity Impact Assessment technical report has been prepared (Practical Ecology 2020) which recommended targeted surveys for six species listed under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), as well as species listed under the (then) Victorian Flora and Fauna Guarantee Act 1988 (FFG Act) and Victorian Advisory List. They include: • Maroon Leek-orchid Prasophyllum frenchii: EPBC Act Endangered, FFG Act listed, endangered in Victoria • Metallic Sun-orchid Thelymitra epipactoides: EPBC Act Endangered, FFG Act listed, endangered in Victoria • Thick-lip Spider-orchid Caladenia tessellata: EPBC Act Vulnerable, vulnerable in Victoria • Wellington Mint-bush Prostanthera galbraithiae: EPBC Act Vulnerable, FFG Act listed, vulnerable in Victoria • Trailing Hop-bush Dodonaea procumbens: EPBC Act Vulnerable, vulnerable in Victoria • Dwarf Kerrawang Commersonia prostrata: EPBC Act Endangered, FFG Act listed, endangered in Victoria • Gippsland Lakes Peppermint Eucalyptus arenicola: rare in Victoria Arcadis was commissioned to undertake the targeted surveys in early October and early November 2020 in areas of identified suitable habitat. Prior to each survey, nearby reference populations of Maroon Leek-orchid, Metallic Sun-orchid, Wellington Mint-bush, Trailing Hop-bush and Dwarf Kerrawang were visited to confirm their stage of development. No EPBC Act listed species were identified within the Construction Footprint, though some species occur immediately adjoining the construction zone. It is understood that Wellington Mint-bush also occurred along the alignment in one location – these plants have since died however a soil-stored seed bank may be present. Four species classified as rare in Victoria were recorded: • Gippsland Lakes Peppermint Eucalyptus arenicola: scattered in several locations • Slender Wire-lily Laxmannia gracilis: one plant located on Sandy Camp Road • Salt Lawrencia Lawrencia spicata: multiple plants located on the edge of Lake Reeve • Ribbed Thryptomene Thryptomene micrantha: multiple plants located west of Lake Reeve. Mitigation measures to avoid impacts to the EPBC Act listed species will be required, including No Go Zone fencing, reinstatement of habitat and construction personnel inductions. Provided these mitigation measures are followed, the Golden Beach Gas Project is not considered likely to have a significant impact on any rare or threatened flora species.

1 Golden Beach Gas Project: Targeted Flora Surveys – Spring 2020

1 INTRODUCTION The proposed Golden Beach Gas Project aims to develop the Golden Beach Gas Field located 3.8 km offshore and involves an onshore pipeline easement and associated track upgrades and infrastructure. The project is currently undergoing the Environment Effects Statement process to address the potential significant impacts to onshore and offshore biodiversity values as well as Aboriginal cultural heritage values. To address the onshore biodiversity impacts, a Terrestrial and Freshwater Biodiversity Impact Assessment technical report has been prepared (Practical Ecology 2020, herein referred to as the Technical Report) which recommended targeted surveys for six species listed under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), as well as species listed under the Victorian Flora and Fauna Guarantee Act 1988 (FFG Act) and Victorian Advisory List (DEPI 2014)1. They include: • Maroon Leek-orchid Prasophyllum frenchii: EPBC Act Endangered, FFG Act listed, endangered in Victoria • Metallic Sun-orchid Thelymitra epipactoides: EPBC Act Endangered, FFG Act listed, endangered in Victoria • Thick-lip Spider-orchid Caladenia tessellata: EPBC Act Vulnerable, vulnerable in Victoria • Wellington Mint-bush Prostanthera galbraithiae: EPBC Act Vulnerable, FFG Act listed, vulnerable in Victoria • Trailing Hop-bush Dodonaea procumbens: EPBC Act Vulnerable, vulnerable in Victoria • Dwarf Kerrawang Commersonia prostrata: EPBC Act Endangered, FFG Act listed, endangered in Victoria • Gippsland Lakes Peppermint Eucalyptus arenicola: rare in Victoria Arcadis was engaged by GB Energy on 28 September 2020 to undertake the required targeted flora surveys in spring 2020. In addition to the species listed above, other rare or threatened species were also targeted during the surveys. In order to protect the ongoing survival of some EPBC Act listed species, a confidential version of this report has been prepared containing all maps and location details. This publicly available version has had the specific location information removed.

1.1 Study Area Targeted surveys were recommended in the Technical Report for the following areas of the Project’s Construction Footprint (referred to as the Footprint): • Kilometre Point (KP) 0.3-2.5 & KP 5 - 6.5 for Maroon Leek-orchid, Metallic Sun- orchid, Thick-lip Spider-orchid • All areas of Damp Sands Herb-rich Woodland (EVC 3), Lowland Forest (EVC 16) and Heathy Woodland (EVC 48) for Wellington Mint-bush, Dwarf Kerrawang, Trailing Hop-bush and Gippsland Lakes Peppermint. While completing the surveys, additional potentially suitable habitat was also surveyed based on the observed habitat for nearby reference populations e.g. Dwarf

2 METHODS

2.1 Field surveys Two botanists, with a minimum of 13 years’ experience each, undertook the field surveys. In order to target the seasonal flowering time of the orchids, two surveys were completed: • 9th and 12th October 2020, KP 0.3-2.5 & KP 5 - 6.5 only • 9th to 12th November 2020, KP 0.3-2.5 & KP 5 - 6.5 and all other areas surveyed as illustrated in Figure 1. Nearby reference populations of Maroon Leek-orchid, Metallic Sun-orchid, Wellington Mint-bush, Trailing Hop-bush, Dwarf Kerrawang and Gippsland Lakes Peppermint were visited prior to surveys in order to confirm the flowering status and development. The field surveys were undertaken in accordance with relevant survey guidelines for survey methods and seasonal timings in order to maximise the chances of being detected. This involved: • All areas of potentially suitable habitat within the footprint were traversed systematically at approximately 5-15 metre intervals depending on suitability of habitat and density of vegetation • If a rare or threatened species was observed, the following information was recorded: – Location details recorded with a GPS – Number of plants As an arborist assessment is to be undertaken for the project, priority was given to focus the surveys on ground layer species. The general extent of areas occupied by Gippsland Lakes Peppermint was recorded in this study, with more detailed location details to be included in the Arborist report.

2.2 Limitations As with all flora surveys, the seasonality of some species can be a limitation for the field survey as they can be easily overlooked if inconspicuous (e.g. underground, emerging, lacking flowers / foliage etc.) during the survey period or identified to genus level only if fertile material is absent. This limitation is most relevant to the EPBC Act listed orchid species targeted during the surveys. In addition to the orchids, Trailing Hop-bush and Dwarf Kerrawang are all quite small plants, making it possible to overlook during the survey. To overcome these risks, two surveys were undertaken during optimal weeks of the year when the orchid species were most likely to be visible and reference populations checked to confirm the stage of development.

2.3 Conservation status The conservation status of species and ecological communities was determined using: • Commonwealth EPBC Act 1999 listings • Victorian FFG Act listings • DELWP’s advisory lists for plants (DEPI 2014) It should be noted that the Victorian FFG Act has recently undergone an amendment that will result in revised conservation statuses and transfer of advisory listed species

6 Golden Beach Gas Project: Targeted Flora Surveys – Spring 2020

to the FFG Act. This process is currently underway and as such the current advisory lists (DSE 2009, 2013, DEPI 2014) are proposed to be obsolete in the near future.

2.4 Nomenclature and taxonomy Plant taxonomy and the use of common names follow the online Victorian Biodiversity Atlas (DELWP 2019b) and VicFlora (VicFlora 2020). For fauna, common names are generally used in the text.

3 RESULTS Locations of the rare and threatened species observed within the Footprint or adjoining environments is discussed below with the locations mapped in Figure 2 and 3. Photos of some plants observed are also provided in Plates 1-6.

3.1 Nationally significant species

3.1.1 Maroon Leek-orchid Prasophyllum frenchii EPBC Act Endangered, FFG Act listed, endangered in Victoria Maroon Leek-orchid was recorded immediately to the south of the construction footprint at Lake Reeve. At least 32 plants were counted during the October 2020 survey. It was observed growing in brackish rush and sedge dominated vegetation. No individuals of this species were observed within the Footprint. To avoid impacts to this species, fencing must be erected at the southern edge of the existing road and changes to hydrology caused by engineering are not to occur. This fence must be as close to the road as possible with footings placed in the slashed road edge, avoiding disturbance to the sedges/rushes off the road batter. Provided these mitigation measures are in place, the project is unlikely to have a significant impact on the species.

3.1.2 Metallic Sun-orchid Thelymitra epipactoides EPBC Act Endangered, FFG Act listed, endangered in Victoria Metallic Sun-orchid was present immediately north of the Footprint at Lake Reeve where it has been planted within an enclosure as part of the species recovery program. No individuals were observed outside the plant-out enclosure. Provided mitigation measures are employed to avoid impacts to the plant-out enclosure area, this species is unlikely to be significantly impacted by the project.

3.1.3 Thick-lip Spider-orchid Caladenia tessellate EPBC Act Vulnerable, vulnerable in Victoria Thick-lip Spider-orchid was not observed during the surveys. It is therefore considered unlikely that the project will significantly impact this species.

3.1.4 Wellington Mint-bush Prostanthera galbraithiae EPBC Act Vulnerable, FFG Act listed, vulnerable in Victoria No Wellington Mint-bush plants were observed within the Footprint. A population of Wellington Mint-bush was observed approximately 100 m south near KP 2 and it is understood that a plant did occur within the Footprint near KP 2-KP 3 but was last seen in spring 2017 and is assumed to have since died (Shannon Dwyer, Gippsland Water, pers.comm.). The small population on Gippsland Water land at Dutson Downs (which primarily occurs within 100 m to 1 km of the Footprint) is one of two populations for the species; the other much larger population being at Holey Plains (c. 32 km west of individuals observed near the project area). This species is strongly fire-dependent for germination and appears to decline in vigour after about 10 years (DSE 2006). The vegetation along the easement in this area has not been burnt in recent decades, with the vegetation immediately south of the easement (where the surviving population is located) was last burnt in 1997

8 Golden Beach Gas Project: Targeted Flora Surveys – Spring 2020

(DELWP 2020b). Based on the recent occurrence of this species within the footprint, the habitat is deemed suitable and it would be likely that a soil stored seedbank may be present that would likely germinate after fire. For many species that rely on disturbance such as fire for germination, soil disturbance in line with that proposed for the Golden Beach Gas Project may also stimulate germination. This is assumed based on similar changes to the vegetation structure and possible seed scarification post disturbance, however the germination ecology of the species has not been studied, nor the longevity of the soil-stored seedbank. The EPBC Act significant impact guidelines for vulnerable species (DoE 2013) that may be triggered by the project include: • reduce the area of occupancy of an important population – Although no plants were observed within the Footprint, it is conservatively assumed that the species is present within the easement as a soil-stored seedbank. Were a fire to pass through the area and stimulate germination for the species, the area of occupancy could be more accurately defined. Therefore, to be conservative, it is assumed that the area of occupancy of the species does include a small part of the footprint in the vicinity of KP 2-KP 3 where the species was recorded three years ago. • adversely affect habitat critical to the survival of a species – As the Dutson Downs population is one of two populations in Victoria, habitat for Wellington Mint-bush within the Footprint near KP 2-KP 3 forms part of the habitat considered critical to the survival of the species. • modify, destroy, remove or isolate or decrease the availability or quality of habitat to the extent that the species is likely to decline. – Due to a lack of fire over recent decades, the quality of the habitat is considered to have decreased likely resulting in a decline in the population. Although the proposed earthworks will overall degrade the quality of habitat, the disturbance may also stimulate germination of Wellington Mint-bush in the absence of fire. The following mitigation measures should ensure that, should plants return after disturbance (due to being present in the soil stored seedbank), the area of occupancy, critical habitat and habitat quality should not be significantly affected: • To protect the soil stored seedbank, careful retention and reinstatement of topsoil between KP 2-KP 3 will be required. This will need to be carefully managed to retain the integrity of the soil, the details of which are included in the Technical Report (Mitigation Measure ID MM FF6; Practical Ecology 2020). • Targeted surveys for the species should occur during the flowering period in years 1, 2, 3 and 5 after construction to search for germinants of this species within the easement. Given the inconspicuous nature of the vegetative material, surveys are recommended to continue to year five as it is anticipated the species would be reproductive by that age and hence less likely to be overlooked. No information is available to confirm the age of reproduction, so this is conservatively based on the reproductive age for Victorian Christmas Bush Prosanthera lasianthos. • If the species is found within the easement at any time, slashing of the easement in that location should cease if possible, or be increased in height to no shorter than 50 cm above ground where slashing is essential for operations. This is likely to allow reproduction to still occur. • If works on the pipeline are to occur in the future that could involve removal of regenerated Wellington Mint-bush plants occurring within the easement, a salvage and translocation plan may be required.

9 Golden Beach Gas Project: Targeted Flora Surveys – Spring 2020

3.1.5 Trailing Hop-bush Dodonaea procumbens EPBC Act Vulnerable, vulnerable in Victoria A nearby population of Trailing Hop-bush was recorded approximately 600 m south of KP 6.7 where it was observed growing in a pine plantation on the bank of a drain. No individuals were recorded within the Footprint and as such it is considered unlikely that the species will be significantly impact by the project.

3.1.6 Dwarf Kerrawang Commersonia prostrata EPBC Act Endangered, FFG Act listed, endangered in Victoria A nearby population of Dwarf Kerrawang was recorded approximately 600 m south of KP 6.7 where it was observed growing in a pine plantation next to a track and near a drain. No individuals were recorded within the Footprint and as such it is considered unlikely that the species will be significantly impact by the project.

3.2 State significant species

3.2.1 Gippsland Lakes Peppermint Eucalyptus arenicola Rare in Victoria Gippsland Lakes Peppermint was observed across the study area. The priority of this targeted survey was to focus on other flora species as an Arborist assessment will occur in the near future which provide detailed mapping of this species. Impacts associated with this species are addressed in the DELWP offset requirements as they take into account the habitat importance models for all state significant species. The Arborist assessment will provide advice on ways to minimise impacts to individual trees during construction. It is also recommended that seed be collected for propagation and used in rehabilitation.

3.2.2 Slender Wire-lily Laxmannia gracilis Rare in Victoria (DEPI 2014) One Slender Wire-lily was observed growing on the western side of Sandy Camp Road within 2 m of the fence. It is unlikely that this plant will be impacted as it is understood the road upgrade works would occur on the eastern side of the road at this location where very minimal native vegetation exists. In addition, impacts to state significant species are addressed in the offset calculations via the incorporation of DELWP’s species habitat importance models. No additional mitigation measures are required.

3.2.3 Salt Lawrencia Lawrencia spicata Rare in Victoria (DEPI 2014) Approximately 15 Salt Lawrencia plants were observed growing within the Footprint at the edge of Lake Reeve. Additional plants may also be present among the robust tussock saltmarsh vegetation. These plants will be impacted by construction and these impacts are addressed in the offset calculations via the incorporation of DELWPs species habitat importance models. No additional mitigation measures are required.

10 Golden Beach Gas Project: Targeted Flora Surveys – Spring 2020

3.2.4 Ribbed Thryptomene Thryptomene micrantha Rare in Victoria (DEPI 2014) Multiple Ribbed Thryptomene plants were observed within the slashed area of the easement near KP 2.3. These plants will be impacted by construction and these impacts are addressed in the offset calculations via the incorporation of DELWPs species habitat importance models. No additional mitigation measures are required.

3.3 Other orchid species The location of other non-threatened orchid species were recorded during the October 2020 survey. These included • Gnat Orchid Cyrtostylis reniformis/robusta • Trim Greenhood Pterostylis concinna • Maroonhood Pterostylis pedunculata • Helmet Orchid Corybas spp. • Small Mosquito-orchid Acianthus pusillus • Trim Sun-orchid Thelymitra peniculata • Tiger Orchid Diuris sulphurea • Notched Onion-orchid Microtis arenaria2 • Nodding Greenhood Pterostylis nutans Some of these orchid species could not confidently be identified to species level due to absence of suitable fertile material. Information on these species was collected to inform the suitability of the site to support a variety of orchid species, demonstrate the level of effort undertaken for the survey and ability to detect a range of species with the survey methods.

2 Only one sample of an Onion-orchid was taken for identification which was identified as Notched Onion-orchid. It is most likely that the thousands of plants observed also include Common Onion-orchid Microtis unifolia.

4 RECOMMENDATIONS AND IMPLICATIONS By implementing the mitigation measures recommended in this report, it is anticipated the impacts to EPBC Act listed species will be avoided. These relate only to mitigating significant impacts to EPBC Act listed flora species recorded in these targeted surveys and build upon the more detailed mitigation measures recommended in the Technical Report. • Erecting No-Go Zone fencing: – Maroon Leek-orchid: at the southern edge of the road for 50 m either side of the mapped Maroon Leek-orchid population. Fence must be located immediately adjoining the road carriageway with footings located on the road or road batter (i.e. not at the bottom of the batter or off the road as this is Maroon Leek-orchid habitat with plants occurring very close to the road). – Metallic Sun-orchid: The population is fenced within an easily identifiable enclosure – no alterations to this fence is to occur, nor entry by personnel or other impacts in the enclosure area. No-Go Zone fencing will be required along the edge of the construction zone. • To protect the soil stored seedbank of Wellington Mint-bush, careful retention and reinstatement of topsoil between KP 2-KP 3 will be required. This will need to be carefully managed to retain the integrity of the soil, the details of which are included in line the Technical Report (Mitigation Measure ID MM FF6; Practical Ecology 2020). • Targeted surveys for Wellington Mint-bush should occur 1, 2, 3 and 5 years after construction to search for germinants of this species within the Footprint. – If germinants are found within the easement, slashing of the easement in that location should cease if possible, or be increased in height to no shorter than 50 cm above ground. • If works on the pipeline are to occur in the future that involve removal of regenerated Wellington Mint-bush plants occurring within the easement, a salvage and translocation plan will be required. • If expansion of Sandy Camp Road occurs, prioritise expansion to the eastern side of the road away from the Slender Wire-lily plant. Ensure No Go Zone fencing is erected. • Mitigation measures for Gippsland Lakes Peppermint will be provided in the arborist report. These will include recommendations for avoiding/reducing damage to large roots encountered during digging operations and compaction of soil. Seed should be collected for propagation and use in reinstatement and rehabilitation works. • Ensure all contractors undergo a brief induction explaining the ecological sensitivity of the study area and identification of the EPBC Act listed species should they be encountered during construction.
