Immediately following the 2019–20 bushfires we worked closely with our government and non-government partners to offer our support. We made a significant contribution to support the recovery of threatened biodiversity impacted by the crisis through many regional, state and Commonwealth forums and the Wildlife and Threatened Species Bushfire Expert Panel.

    Outback wildlife sanctuary in NT undertakes biggest feral cat eradication project in the world ABC NEWS 12 Jun 2017 NT Country Hour By Katrina Beavan http://www.abc.net.au/news/2017-06-12/work-on-feral-animal-proof-fence-underway-in-outback-nt/8609540 Photo: Tim Allard and Joe Schofield stand on what will soon be part of a 9,500 hectare feral animal-free zone. (ABC Rural: Katrina Beavan) Work is underway at Newhaven Wildlife Sanctuary north-west of Alice Springs to create a feral animal-free zone by building a 44-kilometre fence. It has been described as the largest feral cat eradication project in the world, and will eventually span 100,000 hectares. The fence line will initially cover 9,500 hectares for stage one, before expanding to include a larger chunk of the 260,000ha property. Australian Wildlife Conservancy national operations manager Tim Allard said it was a solution to a very big problem. "The feral cat, the numbers vary, but they're decimating millions of native species every night," he said. "We want to get rid of feral cats. At the moment the best way we can do that is by building a fence, eradicating feral animals from within it, and reintroducing native animals. "Once you get an environment without the feral animals inside it, the native population thrives." NATIVE SPECIES TO RETURN Mr Allard said weeds, mismanaged fire, and feral animals were the biggest threats to Australia's native animal population. By keeping feral animals out, it is hoped the sanctuary will see the return of 10 native species, including the central rock rat, mala, numbats, bilbies and phascogales.

  • Development and Application of Survey Methods to Determine
    Development and application of survey methods to determine habitat use in relation to forest management and habitat characteristics of the endangered numbat (Myrmecobius fasciatus) in the Upper Warren region, Western Australia by Anke Seidlitz BSc (Hons) A thesis submitted to Murdoch University to fulfil the requirements for the degree of Doctor of Philosophy in the discipline of Environmental and Conservation Sciences January 2021 Author’s declaration I declare that (a) the thesis is my own account of my research, except where other sources are acknowledged, (b) all co-authors, where stated and certified by my principal supervisor or executive author, have agreed that the works presented in this thesis represent substantial contributions from myself and (c) the thesis contains as its main content work that has not been previously submitted for a degree at any other university. ……………………………. Anke Seidlitz i Abstract Effective detection methods and knowledge on habitat requirements is key for successful wildlife monitoring and management. The numbat (Myrmecobius fasciatus) is an endangered, Australian-endemic marsupial that has experienced major population declines since European settlement. The Upper Warren region (UWR) in south-western Australia contains one of the two remaining natural populations. A lack of effective survey methods has caused a paucity of information regarding this population. This PhD project aimed to develop robust survey methods and determine habitat requirements for the numbat in the UWR. Given the perceived advantages of camera trap technology in wildlife research, camera trap trials were conducted to optimise camera methodologies for numbat detection. Swift 3C wide-angle camera traps positioned at ~25 cm above ground increased numbat detections by 140% compared to commonly used Reconyx PC900 camera traps.

  • Numbat Myrmecobius Fasciatus
    Threatened Species Strategy – Year 3 Priority Species Scorecard (2018) Numbat Myrmecobius fasciatus Key Findings Numbats were once widespread across mainland Australia but declined to only ~300 individuals in WA by the late 1970s, primarily due to predation by foxes and habitat loss, as well as predation by feral cats, and frequent and intense fires. Long term control of introduced predators and careful fire management increased populations, enabling translocations to other sites to re-establish Numbats in parts of their former range, firstly in WA and more recently in SA and NSW. These intensive and long-term recovery efforts have increased the total population to over 1300 individuals. Photo: Alexander Dudley Significant trajectory change from 2005-15 to 2015-18? Yes, rate of increase has improved. Priority future actions • Maintain existing fenced populations and develop plan for metapopulation management. • Intensify feral cat control at all established populations (outside of fences). • Establish further populations across range.

Mecke Abstract We present an assessment of the systematic status of populations currently assigned to Eremiascincus fasciolatus across Australia using morphological data. Our analyses show that these populations actually comprise four species: a large and robust, narrow-banded taxon from eastern Queensland and three slender, desert-dwelling taxa from the western, northern, and south-eastern Australian arid zone respectively. These data necessitate: 1) the redescription of E. fasciolatus, a species endemic to the dry forests of eastern Queensland, 2) the resurrection of E. pallidus for the western taxon, 3) the resurrection of E. intermedius for the northern taxon, and 4) the description of the south-eastern desert-dwelling taxon, which largely occurs in the Lake Eyre Basin, as a new species.
