Bettongia Penicillata Ogilbyi (Woylie)
Advice to the Minister for the Environment, Heritage and the Arts from the Threatened Species Scientific Committee (the Committee) on Amendment to the list of Threatened Subspecies under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Scientific name (common name) Bettongia penicillata ogilbyi (Woylie) 2. Reason for Conservation Assessment by the Committee This advice follows assessment of information gathered through the Commonwealth’s Species Information Partnership with Western Australia, which is aimed at systematically reviewing species that are inconsistently listed under the EPBC Act and the Western Australian Wildlife Conservation Act 1950. The Woylie was listed as endangered under the former Endangered Species Protection Act 1992, but was not transferred to the EPBC Act threatened species list in 1999, reflecting an increase in Woylie distribution and abundance up to about year 2000. This assessment is in response to reported decline since that time. The Committee provides the following assessment of the appropriateness of the Woylie’s inclusion in the endangered category in the EPBC Act list of threatened species. 3. Summary of Conclusion The Committee judges that the subspecies has been demonstrated to have met sufficient elements of Criterion 1 to make it eligible for listing as endangered and of Criterion 2 as vulnerable. The highest level of listing recommended is endangered. 4. Taxonomy The Woylie is conventionally accepted as Bettongia penicillata ogilbyi . Family: Potoroidae. Other common names include: Brush-tailed bettong, Brush-tailed Rat-kangaroo. Indigenous names include: Woylyer and Karpitchi. 5. Description The Woylie is a small potoroid marsupial weighing 1-1.5 kg. It has a distinctive black brush at the end of its tail. -

The Epidemiology of Piroplasm Infection in the Woylie (Bettongia
The epidemiology of Piroplasm Infection in the Woylie (Bettongia penicillata ogilbyi). Photo: Stefania Basile Stefania Basile (30648234) Independent Study Contract Murdoch University 2010 Supervisors: Irwin Peter & Pacioni Carlo i Abstract The woylie (Bettongia penicillata ogilbyi) is an endangered endemic species of the south-west of Western Australia that has experienced a 70-80% decline in the last five years. Among the potential agents for this event, infectious diseases are strongly suspected. The aim of this study was to define the epidemiology of the haemoparasite, Theileria penicillata, in four localities: Karakamia, Keninup, Balban and Warrup. Light microscopy examination (LME) of 274 woylie blood smears was used in the study to establish T. penicillata parasitaemias (via count) and to detect any erythrocyte and leukocyte morphological changes. The protozoa prevalence and average parasitaemias (AP) were considered in relation to gender, location, and body condition; while AP was assessed in relation to haemoglobin (Hb) concentrations, haematocrit (HCT) and red blood cell (RBC) counts to evaluate possible clinical outcomes of the infectious agent. The study highlighted previously unreported morphological findings of the erythrocytic cycle of T. penicillata in the woylie. Parasite infection did not account for any morphological alterations of the RBC and leukocytes. Piroplasm prevalence did not significantly vary between males and females, but was strongly associated with the locality of sampling. Higher and similar AP was detected in Balban and Keninup, while Warrup presented the lowest AP. AP was also strongly associated with Hb only rather than Hb, HCT and RBC count altogether. The reason why this occurred is uncertain and requires further investigation. -

Conservation Science W. Aust. 9 (3) : 239–248 (2015) The diet of foxes (Vulpes vulpes) in fragmented Wheatbelt reserves in Western Australia: implications for woylies (Bettongia penicillata) and other native fauna NICOLA J MARLOW ab *, ANDREW AE WILLIAMS ab, NEIL D THOMAS ab, BRIAN MACMAHON b AND JOHN LAWSON b a Department of Parks and Wildlife, PO Box 51 Wanneroo, WA 6946, Australia b Invasive Animals Co-operative Research Centre 48 Oxford Street, Adelaide, SA 5061, Australia * Corresponding author: [email protected] ABSTRACT The diet of foxes in two fragmented Wheatbelt reserves in south-west Western Australia, Dryandra Woodland (DW) and Tutanning Nature Reserve (TNR), was investigated. Fox baiting commenced in these reserves in the early 1980s and the trap success of woylies (Bettongia penicillata), a threatened species, increased significantly. Woylie capture rates were sustained in TNR until 1992 and in DW until 2000 but then decreased suddenly despite ongoing fox control. The diet of foxes was investigated as part of a larger study examining the reasons for the woylie decline. The contents of 283 fox scats from DW and TNR, and 167 scats from two unbaited sites, Quinns block (QB) and Highbury block (HB), were analysed volumetrically to determine the relative importance of each dietary item. The actual consumption of each item was calculated using digestibility estimates. In baited sites the foxes’ main dietary components were house mice (Mus domesticus, 28%), carrion (sheep, Ovis aries and western grey kangaroo, Macropus fuliginosus; 26%) and rabbits (Oryctolagus cuniculus, 17%). In unbaited sites the main components were carrion (predominately sheep, 60%) and some invertebrates (13%). -
Digging and Soil Turnover by a Mycophagous Marsupial
ARTICLE IN PRESS Journal of Arid Environments Journal of Arid Environments 56 (2004) 569–578 www.elsevier.com/locate/jnlabr/yjare Digging and soil turnover bya mycophagous marsupial Mark J. Garkaklis*, J.S. Bradley, R.D. Wooller Biological Sciences and Biotechnology, Murdoch University, Western Australia 6150, Australia Received 21 October 2002; received in revised form 17 March 2003; accepted 7 April 2003 Abstract The woylie Bettongia penicillata is a small (1 kg) kangaroo-like marsupial that digs to obtain the fruiting bodies of fungi. The number of woylies in a 60 ha area of sclerophyll woodland in south-western Australia was estimated using mark-recapture at 3 month intervals over 3 successive years. The number of new diggings by woylies, determined at the same intervals, allowed an assessment of the rate of digging per individual. This varied three-fold from 38 to 114 diggings per individual per night, with no consistent seasonality. On average, each woylie displaced 4.8 tonnes of soil annually. r 2003 Elsevier Science Ltd. All rights reserved. Keywords: Population size; Bettongia penicillata; Sclerophyll woodland; Biopedturbation 1. Introduction Digging and burrowing are behaviours common to manymammals, particularly in arid and semi-arid ecosystems (Kinlaw, 1999; Whitford and Kay, 1999). For example, the heteromyid rodents, gophers and prairie dogs of North America (Steinberger and Whitford, 1983; Heske et al., 1993; Mooneyand Hobbs, 1994, pp. 73–81; Guo, 1996) porcupines and ibex in Israel (Gutterman and Herr, 1981; Yair and Rutin, 1981; Gutterman, 1997; Alkon, 1999) badgers in Europe (Neal and Roper, 1991, pp. 89–106) aardvark and porcupine in southern Africa (Dean and Milton, 1991; Devilliers and van Aarde, 1994) and the potoroid rat-kangaroos in Australia (Claridge and May, 1994; Garkaklis et al., 1998, 2000) all dig or burrow. -
Bettongia Penicillata
THREATENED SPECIES SCIENTIFIC COMMITTEE Established under the Environment Protection and Biodiversity Conservation Act 1999 The Minister approved this conservation advice and retained this species in the Endangered category, effective from 01/02/2018 Conservation Advice Bettongia penicillata woylie Note: The information contained in this conservation advice was primarily sourced from ‘The Action Plan for Australian Mammals 2012’ (Woinarski et al., 2014). Any substantive additions obtained during the consultation on the draft has been cited within the advice. Readers may note that conservation advices resulting from the Action Plan for Australian Mammals show minor differences in formatting relative to other conservation advices. These reflect the desire to efficiently prepare a large number of advices by adopting the presentation approach of the Action Plan for Australian Mammals, and do not reflect any difference in the evidence used to develop the recommendation. Taxonomy Conventionally accepted as Bettongia penicillata (Gray 1837). Two subspecies are recognised: B. p. penicillata in south-eastern Australia, now Extinct; and B. p. ogilbyi in south-western Australia. The subspecific classification of Bettongia penicillata is unresolved. It is possible that the two subspecies represent distant ends of a cline that terminated in south-eastern Australia (subspecies penicillata ) and south-western Australia (subspecies ogilbyi ). A species in northern Queensland ( B. tropica ) was originally described as a subspecies of B. penicillata , but is no longer recognised as part of that species. This assessment applies to the entire species, B. penicillata , although only one subspecies, B. p. ogilbyi , is extant. Summary of assessment Conservation status Endangered: Criterion 1 (A2)(b)(e) and Criterion 2 B2(a),(b)(ii,iii,iv). -

Department of Parks and Wildlife Science and Conservation Division annual research report 2013–14 DIRECTOR'S MESSAGE There has been much change since we became the Department of Parks and Wildlife in July 2013, with renewed focus on conservation of Western Australia's unique plants and animals and our world- class network of parks, reserves and natural areas. Our Strategic Directions for 2013-14 recognised that science and research play a critical role in effective management of species and ecosystems. In October 2013 the Science Division was amalgamated with the Nature Conservation Division providing new opportunities for science to more directly inform conservation policy and management, and for management requirements and knowledge gaps to set research priorities. While much of our work supports the conservation priorities of the Wildlife corporate goal, we also provide scientific research and information to support delivery of the Parks, Fire, Managed Use and People corporate goals. The combined responsibilities of the divisions are focused around two main areas of Species conservation and Landscape conservation. Our work in species conservation involves activities, such as species and community recovery, wildlife protection and licensing, understanding species biology and taxonomy, while our landscape conservation work is focused on landscape and seascape management, development advice and liaison, understanding ecosystem processes and biological survey. Information systems and monitoring and evaluation link across both species and landscape conservation activities. Across all areas, effective exchange of knowledge and information to support legislation and policy is fundamental to effective delivery of wildlife management outcomes. Partnerships have always been an important means of achieving our outcomes. -
Woylie Conservation Research Project the Woylie Has Been Hailed As One of the Success Stories of Wildlife Conservation Programs Like DEC's Western Shield
DEC Website (2010) http://www.dec.wa.gov.au/content/view/3230/1630/ Woylie Conservation Research Project The woylie has been hailed as one of the success stories of wildlife conservation programs like DEC's Western Shield. In 1996, it was the first endangered species to be removed from listing under the Commonwealth Endangered Species Protection Act 1992 as a direct result of a recovery program. However, a dramatic decline in woylie numbers has been observed over the past few years. With funding from Saving our Species, the State Government's biodiversity conservation initiative, research is now under way to determine possible causes. Juvenile woylie (Photo: Sabrina Trocini)” On 22nd January 2008 the then Environment Minister, David Templeman, re-listed the woylie as endangered under Schedule 1 of the State Wildlife Conservation Act 1950. The assessment of the conservation status of the woylie and the Woylie Conservation Research Project are funded through Saving our Species. About the woylie What is a woylie? Woylies (Bettongia penicillata ogilbyi) are small marsupials that weigh between 1 and 1.5kg. They are distantly related to kangaroos. They are also known as brush-tailed bettongs because of the distinctive black brush they have at the end of their tail. ‘Woylie' is the indigenous Nyoongar name which refers to their ability to carry leaves and DEC Website (2010) http://www.dec.wa.gov.au/content/view/3230/1630/ sticks with their tail. Woylie at Keninup forest Woylies are nocturnal and forage primarily for underground fungi (native truffles). They also eat seeds, tubers and bulbs. What important role does the woylie play in the environment? Woylies make many diggings in search of their favourite food, underground fungi. -

Numbat (Myrmecobius Fasciatus) Recovery Plan
Numbat (Myrmecobius fasciatus) Recovery Plan Wildlife Management Program No. 60 Western Australia Department of Parks and Wildlife February 2017 Wildlife Management Program No. 60 Numbat (Myrmecobius fasciatus) Recovery Plan February 2017 Western Australia Department of Parks and Wildlife Locked Bag 104, Bentley Delivery Centre, Western Australia 6983 Foreword Recovery plans are developed within the framework laid down in Department of Parks and Wildlife Corporate Policy Statement No. 35; Conserving Threatened and Ecological Communities (DPaW 2015a), Corporate Guidelines No. 35; Listing and Recovering Threatened Species and Ecological Communities (DPaW 2015b), and the Australian Government Department of the Environment’s Recovery Planning Compliance Checklist for Legislative and Process Requirements (Department of the Environment 2014). Recovery plans outline the recovery actions that are needed to urgently address those threatening processes most affecting the ongoing survival of threatened taxa or ecological communities, and begin the recovery process. Recovery plans are a partnership between the Department of the Environment and Energy and the Department of Parks and Wildlife. The Department of Parks and Wildlife acknowledges the role of the Environment Protection and Biodiversity Conservation Act 1999 and the Department of the Environment and Energy in guiding the implementation of this recovery plan. The attainment of objectives and the provision of funds necessary to implement actions are subject to budgetary and other constraints affecting the parties involved, as well as the need to address other priorities. This recovery plan was approved by the Department of Parks and Wildlife, Western Australia. Approved recovery plans are subject to modification as dictated by new findings, changes in status of the taxon or ecological community, and the completion of recovery actions.
