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.
