Transformer – Art Installation, Ida Bay Flora and Fauna Habitat Assessment, Including Collision Risk 1st December 2020 For DarkLab, MONA Andrew North [email protected] Philip Barker [email protected] 163 Campbell Street Hobart TAS 7000 Telephone 03. 6231 9788 Facsimile 03. 6231 9877 Transformer, Ida Bay Flora and Fauna Habitat Assessment SUMMARY The proponent DarkLab, of the MONA (Museum of Old and New Art) group, are in the planning phase for a proposed permanent art installation called Transformer at Ida Bay. North Barker Ecosystem Services (NBES) have been engaged to undertake a flora and fauna habitat assessment of the project area, including a collision risk assessment for the swift parrot. Vegetation Four native TASVEG vegetation units have been recorded within the project area, none of which are threatened under the EPBCA or the NCA: - DOB – Eucalyptus obliqua dry forest - MBS – buttongrass moorland with emergent shrubs - SHW – wet heathland - SMR – Melaleuca squarrosa scrub Threatened Flora The footprint does not overlap with any known occurrences of threatened flora and it is not expected to have any unanticipated impacts in relation to undocumented occurrences. Weeds The survey area was found to be relatively free of serious weeds. Only two declared weeds were recorded in small amounts. No symptomatic evidence of Phytophthora cinnamomi was observed within the site, but the wet heath community is particularly susceptible to its impacts. Threatened Fauna The property and the broader Ida Bay contains potential foraging and nesting habitat for the swift parrot, including habitat patches and elements (such as hollow-bearing trees) around the proposed footprint. Conclusions and Recommendations In terms of natural values, potential direct impacts (e.g. habitat clearance) due to works from the present proposal will be relatively minor on account of the footprint being relatively small and having limited intersection with conservation significant values. The most significant value associated with the site is potential foraging and nesting habitat for the swift parrot. Our assessment has however shown that the proposal will require negligible levels of impact to potential swift parrot habitat and poses only a low level of risk in relation to collision-induced mortalities. The following recommendations are made regarding general management of the proposal area and to ensure minimal impacts to conservation significant values. Native Vegetation - Concentrate direct and irreversible clearance within areas of non-native vegetation (modified land) as much as possible. - Apply a micro-siting approach (with the aid of an ecologist) to areas of the final footprint within native vegetation – the micro-siting should aim to make minor adjustments to the footprint on the ground by selecting localised areas with relatively less important values (e.g. lower condition areas), as well as maintaining variation within i a community across the project area and local areas containing important values. North Barker Ecosystem Services MON016: 2020_12_01 v. 2.0 Transformer, Ida Bay Flora and Fauna Habitat Assessment - In cases of redesign or additions, maximise the proportion of the footprint within non- native (modified) vegetation and avoid native vegetation (as well as habitat for threatened species). - Clearly demarcate the permitted impact area either in situ and/or clearly on construction plans and specify on all contractor agreements that works, vehicles and materials must be confined within the designated impact areas. - Areas of native vegetation beyond the impact footprint should be designated as exclusion zones and marked on the ground and in construction plans to the degree necessary to ensure no inadvertent impacts occur. - Incorporate a revegetation plan into the post-construction requirements, covering areas where clearance of native vegetation is not required to be a permanent loss (e.g. borrow pits [if required], temporary access routes and temporary construction disturbance footprints). The plan should outline suitable species for revegetation (sourced from the local environment), as well as revegetation specifics, such as seed application rates, use of established plants, specific planting details, etc. Introduced Plants and Pathogens - Prior to and during construction: o A Construction Environmental Management Plan (or similar instrument) should include requirements for the contractor or proponent to undertake primary control (eradication) of the blackberry and Spanish heath infestations presented in Figure 4, as well as general hygiene principles (particularly the use of clean and disinfected plant and equipment) that limit the potential for introduction of weeds or pathogens. - Post works: o During the next spring/summer season at least three months after construction is completed (not sooner), the proponent should arrange a weed and pathogen inspection of the site, with scope for subsequent control actions if required. - During operations: o Users should be directed to stay on paths/tracks and other formed surfaces with signage. o The proponent may consider an educational sign within the visitor centre (or elsewhere) that covers weeds and pathogens. o The operators should install (prior to opening) and maintain a shoe wash station at the start of the path consistent with those used in national parks and reserves. o At least one staff member should be trained in basic identification of weeds (including blackberry and Spanish heath) and symptomatic evidence of PC, supported by an action plan that outlines what to do if weeds or disease symptoms are observed. o The proponent should arrange biennial spring/summer weed and disease inspections of the site, with scope for subsequent control actions if required. ii North Barker Ecosystem Services MON016: 2020_12_01 v. 2.0 Transformer, Ida Bay Flora and Fauna Habitat Assessment Threatened Fauna - Implement a monitoring program of both swift parrot use of the site and collision incidences. The program should include: o Annual pre-season checks on foraging trees and the likelihood of flowering food plants within the vicinity of the development. o Utilisation surveys within seasons where food plants on site are flowering and/or the Southern Forests SPIBA is known to be host to significant numbers of breeding pairs. o Regular systematic patrols around the development buildings to document bird collision mortalities. o Mitigation strategies for if mortalities occur in relation to particular design elements or habitat variables (e.g. flowering events) – mitigation options may include alterations to the building designs or facades to the degree necessary. iii North Barker Ecosystem Services MON016: 2020_12_01 v. 2.0 Transformer, Ida Bay Flora and Fauna Habitat Assessment File Control and Contributors Project Transformer – art installation Location PID: 5267994, title ref: 238040/1, 328 Lune River Road, Ida Bay, Tasmania – part of the Ida Bay State Reserve Proponent DarkLab, Museum of Old and New Art (MONA) Proponent contact Tim Lathouris - [email protected] NBES job code MON016 NBES project manager Grant Daniels – 0400 104 649 [email protected] Field inspections and photos General flora and fauna: Grant Daniels - 29/11/2020 Collision risk: Dave Sayers and Erin Harris - 2/6/2020; 19/11/20 Reporting Grant Daniels*, Erin Harris**, Dave Sayers** and Phil Barker** * general report; ** collision risk contributions only Mapping Jacques Demange External consultations Dejan Stojanovic, Australian National University – assessment of swift parrot habitat on site to aid collision risk assessment.

    Commonwealth Listing Advice on Alpine Sphagnum Bogs And

    Advice to the Minister for the Environment, Heritage and the Arts from the Threatened Species Scientific Committee (the Committee) on Amendments to the List of Ecological Communities under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Summary of conservation assessment by the Committee This advice follows the assessment of information provided by a nomination to list the Alpine Bog Community as a threatened ecological community. The nomination was made available for public exhibition and comment for a period of two months. The Committee had regard to all public and expert comments that were relevant to the survival of the ecological community. The Committee judges that the ecological community has been demonstrated to have met sufficient elements of: • Criterion 2 to make it eligible for listing as endangered; • Criterion 3 to make it eligible for listing as endangered; and • Criterion 4 to make it eligible for listing as endangered. 2. Name of the ecological community A nomination was received for the Alpine Bog Community. Alpine bogs are commonly found in the vicinity of alpine fens, and have been identified as being dependent on these (VSAC, 1991a). In order to make identification easier in the field, to recognise the importance of Sphagnum species to alpine bogs, and to acknowledge the interdependency of alpine bogs, fens and the natural drainage lines that connect them, the Committee recommends that the name of the ecological community be changed to the “Alpine Sphagnum Bogs and Associated Fens” ecological community. 3. Description The Alpine Sphagnum Bogs and Associated Fens ecological community generally has sharp boundaries and is easily delineated from other alpine vegetation communities.

Copying of any part of this thesis is prohibited for two years from the date this statement was signed; after that time limited copying is permitted in accordance with the Copyright Act 1968. Karen A. Johnson iii iv Abstract Relationships between plants and their pollinators are thought to have played a major role in the morphological diversification of angiosperms. The epacrids (subfamily Styphelioideae) comprise more than 550 species of woody plants ranging from small prostrate shrubs to temperate rainforest emergents. Their range extends from SE Asia through Oceania to Tierra del Fuego with their highest diversity in Australia. The overall aim of the thesis is to determine the relationships between epacrid floral features and potential pollinators, and assess the evolutionary status of any pollination syndromes. The main hypotheses were that flower characteristics relate to pollinators in predictable ways; and that there is convergent evolution in the development of pollination syndromes.

The Huntingfield area has a varied vegetation, including substantial areas ofEucalyptus amygdalina heathy woodland, heath, buttongrass moorland and E. amygdalina shrubbyforest, with smaller areas ofwetland, grassland and E. ovata shrubbyforest. Six floristic communities are described for the area. Two hundred and one native vascular plant taxa, 26 moss species and ten liverworts are known from the area, which is particularly rich in orchids, two ofwhich are rare in Tasmania. Four other plant species are known to be rare and/or unreserved inTasmania. Sixty-four exotic plantspecies have been observed in the area, most ofwhich do not threaten the native biodiversity. However, a group offire-adapted shrubs are potentially serious invaders. Management problems in the area include the maintenance ofopen areas, weed invasion, pathogen invasion, introduced animals, fire, mechanised recreation, drainage from houses and roads, rubbish dumping and the gathering offirewood, sand and plants.

Ecological influences in the biogeography of the aus- tral sedges. MSc dissertation. University of Cape Town. Cape Town. February 2016. supervisors: A. Muthama Muasya G. Anthony Verboom ABSTRACT The biogeographic history of a species is a result of both stochastic processes such as dispersal and habitat filters that determine where a population with a given set of biological requirements can become es- tablished. In this dissertation, I examine the geographical and ecolog- ical distribution of the sedge tribe Schoeneae in conjunction with its inferred speciation history in order to determine the pattern of disper- sal and the environmental factors that have influenced establishment. The biogeographic reconstruction indicates numerous transoceanic dispersal events consistent with random diffusion from an Australian point of origin, but with a bias towards habitats with vegetation type and moisture regime similar to the ancestral conditions of the given subgroup (open and dry habitats in the majority of cases). The global distribution of the tribe also suggests a preference for low-nutrient soils, which I investigate at the local (microhabitat) scale by contrast- ing the distributions of the tribes Schoeneae and Cypereae on the Cape Peninsula along soil fertility axes.
