Since European settlement at least 10% of Australia’s mammals have become extinct. Quolls are mainland Australia’s largest surviving marsupial carnivore. When Captain Cook recorded ‘quolls’ as their Aboriginal name in 1770, it is thought that most of Australia was inhabited by at least one quoll species. However, since then quolls have declined in the wild. There are four species of quoll found in Australia; the northern quoll, the eastern quoll, the western quoll, and the spotted- tailed quoll. In New Guinea there are two species of quoll; the New Guinea quoll and the bronze quoll. All quoll species are listed on the IUCN Red List. Under Federal legislation in Australia, three of the four species are listed as being threatened, the spotted-tailed quoll, western quoll and northern quoll. The fourth species, the eastern quoll, is not currently listed as being nationally threatened, however its status is discussed in greater detail during this workshop. Further information on the current distribution of all quoll species can be found in the Current Status and Distribution Updates of the Theme 1 Panel Discussion from this workshop. The following recovery teams and plans have been established for each quoll species; • Northern Quoll, Dasyurus hallucatus • National Recovery Plan in preparation, contact Brydie Hill, TSN, or Simon Ward, NRETA • No formalised recovery team • Eastern Quoll, • No recovery plan under development • No recovery team • Spot-tailed Quoll, Dasyurus maculatus (Spotted-tailed Quoll, Tiger Quoll) • National Recovery Plan in preparation, contact Gary Backhouse, DSE • ACT Action Statement (2005) • Victorian Action Plan (2003) • No formalised recovery team • Western Quoll, Dasyurus geoffroii (Chuditch) • Review of National Recovery Plan in preparation, contact Keith Morris, WA DEC • Expired National Recovery Plan (1992-2001) • No formalised recovery team • New Guinea Quoll, Dasyurus albopunctatus • No recovery plan or team established • Bronze Quoll, Dasyurus spartacus • No recovery plan or team established WWF-Australia and the Threatened Species Network (TSN) invited conservation managers and researchers from all over Australia and New Guinea to attend the first ever quoll workshop, 15-16 April, 2008, The aim of the quoll workshop was to initiate steps towards achieving coordinated implementation of quoll conservation in Australasia and to ensure that appropriate actions are being undertaken to conserve all quoll species. The workshop helped to set priorities and improve communication and cooperation in order to pursue this first step. 4 WORKSHOP SUMMARY Objective: The key objective of the workshop was to find the best way to achieve coordinated action and implementation of key priorities for quoll conservation in Australasia. Key aims of the workshop to help pursue this objective were to: 1. Identify common national and international issues and priorities across all quoll species 2. Share new research and lessons learned 3. Support collaborative networks and communication among researchers and conservation managers 4. Identify clear actions to progress quoll conservation into the future Themes: Presentations and workshops to pursue these key aims were provided over the two days through four key sessions: Theme 1: Updates and new information Theme 2: Threats and interactions Theme 3: Conservation actions Theme 4: Barriers and solutions • Workshop participants © Helen Pitman/WWF 5 Theme 1: Updates and new information Presentations for this introductory theme provided overviews of new research and current knowledge gaps, quolls in New Guinea, and suggested priority actions for future quoll conservation. A number of presentations were given which aimed to provide an overview of WWF-Australia’s reasoning for the workshop, of which summaries are provided below. Tammie Matson, Program Leader Species, WWF-Australia WWF-Australia Flagship Species Approach Tammie Matson outlined the goals and activities of WWF-Australia’s Species Program, particularly in relation to the organisation’s Flagship approach. WWF has selected national flagship species on which to focus its work. These species (or groups of species) are representative of threats and/or habitats that relate to many other plants and animals, so that by conserving the flagship species there will be a significant broader biodiversity benefit. Flagship species are also chosen for their charismatic and iconic qualities, thereby having the capacity to mobilise public support and action for conservation. Kat Miller, Program Manager – Threatened Species, WWF-Australia Threatened Species Network and Quoll Conservation Kat Miller summarised the role of the Threatened Species Network, which is a joint program of WWF-Australia and the Australian government. Kat also described the Threatened Species Network’s role to date in quoll conservation, which ranges geographically from Tasmania to the Northern Territory, working with community and indigenous groups, government agencies and policy makers for the benefit of gathering better information and reducing the threats to quoll species. Just some of the quoll projects with which TSN have been involved include; • the translocation of northern quoll to cane-toad free offshore islands in the NT • working with Traditional Owners, Lianthawirriyarra Sea Ranger Unit and NT Parks and Wildlife Service to establish a monitoring program for northern quolls on the Sir Edward Pellew Islands. • the establishment and support of the Qld Quoll Seekers Network • numerous habitat enhancement projects for the spot-tailed quoll in Queensland, NSW, Victoria and WA • regional Victorian spot-tailed quoll surveys and community training on spot-tailed quoll and habitat identification • tracking of western quolls released into Denmark State Forest, WA, and engagement with local community in baiting program Karen Firestone, Taronga Conservation Society Australia Overview of New Research and Current Knowledge Gaps Karen Firestone identified a number of knowledge gaps in quoll conservation. In particular she identified gaps regarding the taxonomic status of quolls, the phylogeographical status of northern quolls and the genetic response of northern quolls to cane toads. She noted a general lack in understanding of the basic biology and ecology of New Guinea quolls and the factors limiting bronze quoll distribution. Both species are found only in New Guinea. As well as a need for further research on New Guinea and bronze quolls, there is a need for further understanding of spotted-tailed quolls in north Queensland and Tasmania. Karen outlined recent research that has focussed on quolls and their response to cane toads. This research has found that in Queensland cane toads have reduced quoll populations, but that persisting populations of quolls still remain. In the Northern Territory there have been localised extinctions caused by cane toads. In Western Australia there has been no exposure of quolls to cane toads to date but the toad front will inevitably cross into Western Australia in the near future. 6 Plenary The following discussion and questions were covered following the presentation. Karen Firestone indicated a desire for a dedicated field project focusing on New Guinea and bronze quolls. She also agreed to accept genetic samples from work conducted by the workshop participants. Q. What yard sticks are used for determining ESU (Evolutionary Significant Units)? A. Usually it’s a divergence of 5% in mammals. Q. Has anyone tried breeding the bronze quoll with the New Guinea quoll? A. So far no, it’s not clear if they would produce viable offspring. Q. Are the eastern quolls the most ancestral species? A. No, the northern quolls are. Q. Are cane toads present in the TransFly? A. They are, but so far they are not widely spread. Q. What are the current priorities of the PNG government departments? A. At the moment the priorities encompass community and sustainable development, thus there is very little support for conservation research. Q. What other species are connected with quoll conservation in New Guinea? A. Possibly bats and water rats, but it’s not really known at this time. {Ed. - Depending on which species of quoll you refer to, these could be tree kangaroos, cuscus, possums, rats and other small mammals, } Steven Hamilton, University of New South Wales Quolls of New Guinea Steve outlined the key factors relevant to quoll conservation in New Guinea. He noted that two of the six quoll species occur in New Guinea: the Bronze quoll Dasyurus spartacus and the New Guinea quoll

    Felixer™ Grooming Trap Non-Target Safety Trial: Numbats July 2020 Brian Chambers, Judy Dunlop, Adrian Wayne Summary Felixer™ cat grooming traps are a novel and potential useful means for controlling feral cats that have proven difficult, or very expensive to control by other methods such as baiting, shooting and trapping. The South West Catchments Council (SWCC) and the Department of Biodiversity, Conservation and Attractions (DBCA) plan to undertake a meso-scale trial of Felixer™ traps in the southern jarrah forest where numbats (Myrmecobius fasciatus) are present. Felixer™ traps have not previously been deployed in areas with numbat populations. We tested the ability of Felixer™ traps to identify numbats as a non-target species by setting the traps in camera only mode in pens with four numbats at Perth Zoo. The Felixer™ traps were triggered 793 times by numbats with all detections classified as non-targets. We conclude that the Felixer™ trap presents no risk to numbats as a non-target species. Acknowledgements We are grateful Peter Mawson, Cathy Lambert, Karen Cavanough, Jessica Morrison and Aimee Moore of Perth Zoo for facilitating access to the numbats for the trial. The trial was approved by the Perth Zoo Animal Ethics Committee (Project No. 2020-4). The Felixer™ traps used in this project were provided by Fortescue Metals Group Pty Ltd and Roy Hill Mining Pty Ltd. This trial was supported by the South West Catchments Council with funding through the Australian Government’s National Landcare Program. ii Felixer™ - Numbat Safety Trial

The text of this thesis contains no material previously published or written unless due reference to this material is made. This work has neither been presented nor is currently being presented for any other degree. Scott Lindsay 30 March 2014. i SUMMARY Neosporosis is a disease of worldwide distribution resulting from infection by the obligate intracellular apicomplexan protozoan parasite Neospora caninum, which is a major cause of infectious bovine abortion and a significant economic burden to the cattle industry. Definitive hosts are canid and an extensive range of identified susceptible intermediate hosts now includes native Australian species. Pilot experiments demonstrated the high disease susceptibility and the unexpected observation of rapid and prolific cyst formation in the fat-tailed dunnart (Sminthopsis crassicaudata) following inoculation with N. caninum. These findings contrast those in the immunocompetent rodent models and have enormous implications for the role of the dunnart as an animal model to study the molecular host-parasite interactions contributing to cyst formation. An immunohistochemical investigation of the dunnart host cellular response to inoculation with N. caninum was undertaken to determine if a detectable alteration contributes to cyst formation, compared with the eutherian models. Selective cell labelling was observed using novel antibodies developed against Tasmanian devil proteins (CD4, CD8, IgG and IgM) as well as appropriate labelling with additional antibodies targeting T cells (CD3), B cells (CD79b, PAX5), granulocytes, and the monocyte-macrophage family (MAC387).

  • Marsupial Mole Survey 2008
    Marsupial Mole Survey Etadunna Station, June 2008 Reece Pedler Community Fauna Officer SA Arid Lands NRM Board Background Marsupial Moles are a little-known creature found in the sandy inland regions of Australia. Their extremely unusual life habits involve spending almost their entire lives beneath the soil surface. Consequently very little is known about the most basic details of their lives including their behavior, diet, status and distribution. In South Australia, Marsupial Moles are currently known only from the far north and west of the state, including the Anangu Pitjantjatjara Lands, the Maralinga Tjarutja Lands and the western side of the Simpson Desert. However, the difficulties in detecting moles and the lack of survey effort aimed at searching for them in other areas means that their range could well be more widespread than currently known. The aim of the current survey was to follow up on a possible sighting of a Marsupial Mole, which was made by Andrew Black on Etadunna Station in 2002 while excavating with a bulldozer. A previous trip was made to Etadunna in 2006 by Michelle Watson from the SA Arid Lands NRM to try and locate the area of the sighting and look for tracks of other small mammal species. At this time, the area of the sighting was thought to be near Georgia Bore, approximately 50 km west of the Birdsville Track in the southern area of the Tirari Desert. However, after talking directly with Andrew (in May 2008) it was discovered that the sighting was actually made near Boolcaltaninna Bore, to the east of the Birdsville track, north of Lake Gregory.

It is found from south-eastern Queensland all the way to the northern parts of the Western Australian coast. Populations have declined across much of this range, particularly as a result of the spread of the cane toad.

  • The Hunter and Biodiversity in Tasmania
    The Hunter and Biodiversity in Tasmania The Hunter takes place on Tasmania’s Central Plateau, where “One hundred and sixty-five million years ago potent forces had exploded, clashed, pushed the plateau hundreds of metres into the sky.” [a, 14] The story is about the hunt for the last Tasmanian tiger, described in the novel as: “that monster whose fabulous jaw gapes 120 degrees, the carnivorous marsupial which had so confused the early explorers — a ‘striped wolf’, ‘marsupial wolf.’” [a, 16] Fig 1. Paperbark woodlands and button grass plains near Derwent Bridge, Central Tasmania. Source: J. Stadler, 2010. Biodiversity “Biodiversity”, or biological diversity, refers to variety in all forms of life—all plants and animals, their genes, and the ecosystems they live in. [b] It is important because all living things are connected with each other. For example, humans depend on living things in the environment for clean air to breathe, food to eat, and clean water to drink. Biodiversity is one of the underlying themes in The Hunter, a Tasmanian film directed by David Nettheim in 2011 and based on Julia Leigh’s 1999 novel about the hunt for the last Tasmanian Tiger. The film and the novel showcase problems that arise from loss of species, loss of habitat, and contested ideas about land use. The story is set in the Central Plateau Conservation Area and much of the film is shot just south of that area near Derwent Bridge and in the Florentine Valley. In Tasmania, land clearing is widely considered to be the biggest threat to biodiversity [c, d].

    FAUNA of AUSTRALIA 20. THYLACINIDAE JOAN M. DIXON 1 Thylacine–Thylacinus cynocephalus [F. Knight/ANPWS] 20. THYLACINIDAE DEFINITION AND GENERAL DESCRIPTION The single member of the family Thylacinidae, Thylacinus cynocephalus, known as the Thylacine, Tasmanian Tiger or Wolf, is a large carnivorous marsupial (Fig. 20.1). Generally sandy yellow in colour, it has 15 to 20 distinct transverse dark stripes across the back from shoulders to tail. While the large head is reminiscent of the dog and wolf, the tail is long and characteristically stiff and the legs are relatively short. Body hair is dense, short and soft, up to 15 mm in length. Body proportions are similar to those of the Tasmanian Devil, Sarcophilus harrisii, the Eastern Quoll, Dasyurus viverrinus and the Tiger Quoll, Dasyurus maculatus. The Thylacine is digitigrade. There are five digital pads on the forefoot and four on the hind foot. Figure 20.1 Thylacine, side view of the whole animal. (© ABRS)[D. Kirshner] The face is fox-like in young animals, wolf- or dog-like in adults. Hairs on the cheeks, above the eyes and base of the ears are whitish-brown. Facial vibrissae are relatively shorter, finer and fewer than in Tasmanian Devils and Quolls. The short ears are about 80 mm long, erect, rounded and covered with short fur. Sexual dimorphism occurs, adult males being larger on average. Jaws are long and powerful and the teeth number 46. In the vertebral column there are only two sacrals instead of the usual three and from 23 to 25 caudal vertebrae rather than 20 to 21.

    Intot Obliv i The disappearing native mammals of northern Australia Compiled by James Fitzsimons Sarah Legge Barry Traill John Woinarski Into Oblivion? The disappearing native mammals of northern Australia 1 SUMMARY Since European settlement, the deepest loss of Australian biodiversity has been the spate of extinctions of endemic mammals. Historically, these losses occurred mostly in inland and in temperate parts of the country, and largely between 1890 and 1950. A new wave of extinctions is now threatening Australian mammals, this time in northern Australia. Many mammal species are in sharp decline across the north, even in extensive natural areas managed primarily for conservation. The main evidence of this decline comes consistently from two contrasting sources: robust scientifi c monitoring programs and more broad-scale Indigenous knowledge. The main drivers of the mammal decline in northern Australia include inappropriate fi re regimes (too much fi re) and predation by feral cats. Cane Toads are also implicated, particularly to the recent catastrophic decline of the Northern Quoll. Furthermore, some impacts are due to vegetation changes associated with the pastoral industry. Disease could also be a factor, but to date there is little evidence for or against it. Based on current trends, many native mammals will become extinct in northern Australia in the next 10-20 years, and even the largest and most iconic national parks in northern Australia will lose native mammal species. This problem needs to be solved. The fi rst step towards a solution is to recognise the problem, and this publication seeks to alert the Australian community and decision makers to this urgent issue.
