This report is dedicated to the memory of Andy Doldissen, a kindred bushcare spirit, wildlife photographer and an inspiration to us all. Acknowledgements This study was commissioned by the City of Canada Bay Council (CCBC) and coordinated by Robert Stevenson of Council’s Bushcare section. The project was funded by the NSW Government’s former Waste and Sustainability Improvement Payment Program. A number of organisations and individuals contributed valuable local knowledge, ecological and historical data, photographic images and field assistance. Robert Stevenson (CCBC Bushcare Coordinator) and Daniel Oldfield (CCBC Bushcare Team Leader) provided photographs, copies of local biodiversity studies, bushland regeneration reports and planning and heritage investigations, assistance during field surveys and coordinated the project’s community information day. David Sansome (Local Studies Librarian, CCBC Library) kindly allowed access to local European and Indigenous historical resources including the Local History Room collection. Marieke Jansen produced maps of the study area including recommended target zones using ArcGIS Desktop 10.2 from field and Council-supplied data. Jen O’Meara of Sydney Olympic Park Authority (SOPA) supplied extensive fauna occurrence datasets for Sydney Olympic Park and permitted survey access to Bicentennial Park. Judy Harrington of SOPA and BirdLife Australia accompanied A.H. on day and night surveys of Bicentennial Park and other sites. Dion Hobcroft provided his local bird records. The NSW Office of Environment and Heritage provided access to NSW Wildlife Atlas data via BioNet. Teresa Anderson and Deborah Jenkins of NSW Health allowed access to Yaralla Estate - comprising Yaralla House (Dame Eadith Walker Hospital) and the Yaralla Cottages and Rivendell Child Family and Adolescent Unit (originally Thomas Walker Convalescent Hospital) at Concord West and were very supportive of the project. Tim Gahan and Mark Parker provided access to Concord Golf Course as did Aaron Fluke (CCBC) for Massey Park and Barnwell Park Golf Courses. Seven (7) local schools participated in the project. The NSW Department of Education & Communities through the principals of these schools kindly provided before or after-hours access to conduct the surveys. They included Concord High School (Jacqueline Koob), Concord Public School (Anna Vountoulas), Strathfield North Public School (Frances Brewer), Mortlake Public School (Elizabeth Bransgrove and Bernadette Wilson), Abbotsford Public School (Chris Johnson), Drummoyne Public School (Gail Charlier) and Russell Lea Infants School (Lesley Pike). Glenys Grunfelder of Russell Lea Infants School supplied information on fauna species sighted on the school grounds. I am very grateful to interested local residents and Bushcare and WIRES volunteers for their support and enthusiastic contribution of local knowledge, fauna observations, photographs and field assistance in the project. They included Andy Doldissen, Geoff Duggan, Dion Hobcroft, Judy Harrington, Hale Saldamli, Kris Spasojevic, Frances Davis, Merle Newton, Penny and John Smith, Annette Ellison, Chris Paine, Mandy Falkenmire, Peter Sweeney and Esther Hughes. All of these people accompanied me on some of the site surveys. Kris Spasojevic also provided WIRES contacts for local fauna rescue and release data. Andy Doldissen markedly improved the quality of the photographic record of fauna studied in the project by contributing his images and skills. Geoff Duggan put me in contact with local Cabarita foreshore residents to search for Rakali, together with Andy. Geoff also provided helpful local history of industrial land use around Cabarita, Abbotsford and Mortlake. Dion Hobcroft supplied his own recent records of avifauna observed in the LGA. Ron Pirotta contributed skink photographs from Figtree Bay. Lois Michel and Pam Regan provided access to the City of Canada Bay Museum and Heritage Society library. The Fauna of City of Canada Bay LGA: 2013-2014 – InSight Ecology – August 2014 1 Executive summary The City of Canada Bay is one of the oldest urban landscapes in Australia. The traditional land of the Wangal People of the Eora Nation, the area was explored by Europeans soon after the arrival of the First Fleet in 1788 and settled from 1793. This convoluted series of bays, jutting peninsulas and undulating country was teeming with biodiversity. Eventually, however, as the bush was cleared to make way for farms, housing and industry many species of native plants and animals disappeared or retreated to less accessible and arable river valleys to the north or south. Today’s indigenous plant and animal communities of the City of Canada Bay Local Government Area (LGA) survive in some of the last stands of remnant native vegetation in inner-western Sydney. They are the relicts of once floristically and structurally diverse ecosystems – small pockets of Sydney Turpentine-Ironbark Forest (STIF) on clay soils of undulating country, patches of eucalypt woodland on shallow Hawkesbury Sandstone soils of peninsula headlands and strips of swamp oak and mangrove forest along bays with tidal mudflats. Tiny remnants of estuarine saltmarsh still survive at just a few sites in the LGA – larger patches were infilled to establish golf courses and parkland from the 1930s to 1970s. This caused birds such as the saltmarsh specialist, White-fronted Chat, to disappear from the LGA. Less than 2% of the LGA’s original native vegetation remains today. Despite this process of pronounced habitat loss, fragmentation and species attrition, the City of Canada Bay is home to a remarkably diverse suite of indigenous fauna. Many of these are birds – some fly thousands of kilometres each year from the northern hemisphere to forage along the City’s mudflats and mangroves. Others are bush birds that have managed to survive in STIF remnants on the Yaralla and Rivendell peninsulas – the joint jewels in the City’s biodiversity crown. Australia’s favourite bird – the Superb Fairy-wren – is a genuine success story with several populations living and breeding in urban home gardens and bush remnants
