Our Science Strategic Plan and Program Plans articulate how our work contributes to delivery of the biodiversity science priorities for the State as the knowledge generated by our science is essential to ensure we conserve and value add to the unique biodiversity we have around us. I acknowledge the start of 2020 presented unforeseen challenges due to the coronavirus global pandemic. While some field work was disrupted by the travel restrictions, we maintained delivery of a high level of quality science to inform conservation management. I thank all our Biodiversity and Conservation Science staff for their perseverance during this disrupted time. We have continued the renewal of our capability to provide innovative science that informs current and future conservation initiatives. The strength of Biodiversity and Conservation Science resides in our people, and in the past year we have welcomed new staff with expertise in ecosystem genomics, wetland ecology, community ecology, plant genetics, water monitoring, conservation policy and species management. 2020 is the 50th anniversary of our Herbarium journal Nuytsia and we are celebrating with the publication of names and descriptions for 50 new plant species throughout the year. Other highlights of our scientific research includes emergency actions and monitoring to manage the impacts of bush fire on western ground parrot in Cape Arid National Park and on threatened plants and ecological communities in the Stirling Range National Park, implementation of water quality monitoring in the Swan-Canning river system, a survey of Lake Carnegie to inform identification of conservation values, temporal analysis of seagrass extent and response to a marine heatwave for the Shark Bay World Heritage Area, analysis of long term thinning experiments to inform forest management, and the first bandicoot born on Dirk Hartog Island following translocation. The great science work we undertake is facilitated by the excellent support of our administration staff. As we continue to deliver excellent science to underpin effective biodiversity conservation in Western Australia we look to new opportunities. The Premier announced $7.7 million funding for the Biodiversity Information Office (BIO) to be established in DBCA and support the broader Environment Online initiative in partnership with the Commonwealth Digital Environmental Assessment Project. BIO will collate, curate, and make available biodiversity data to provide key information to support environmental management and conservation in Western Australia. I look forward to delivering on this exciting initiative in the coming years. We remain active in pursuing opportunities and seeking innovative ways for delivering science to support conservation, and we continue to communicate our scientific outputs and outcomes to a diverse range of audiences through a variety of avenues, including scientific papers, technical and popular articles, social media, conference talks, seminars and other presentations. I am pleased that we continue our effective partnerships with conservation staff in the Parks and Wildlife Service, Kings Park and Botanic Garden, Perth Zoo and the Rottnest Island Authority. We continue to engage with a wide range of external partners at universities, CSIRO, NGOs, WABSI, WAMSI and the NESP Threatened Species Recovery and Northern Australia Environmental Resources hubs. We continue to have a large number of active science partnerships and our scientists are involved in co-supervision of many Honours, Masters and PhD students. I look forward to continuing to work effectively with all our partners to deliver excellent science that informs con- servation and management of our diverse plants, animals and ecosystems, and supports effective management of our parks and reserves, delivery of our fire program and engagement of visitors with our natural attractions.

    Corella, 2004, 28(3): 79-81 DIET OF THE EASTERN BRISTLEBIRD Dasyornis brachypterus IN NEW SOUTH WALES LINDA GIBSON1 and JACK BAKER2 'Australian Museum, 6 College Street, Sydney, New South Wales 2010 'Institute of Conservation Biology. Department of Biological Sciences, University of Wollongong, New South Wales 2522 Received: I October 2003 7 The diet of the Eastern Bristlebird Oasyomis brachypterus in New South Wales was determined from observations and an analysis of faeces, stomach and gut contents of 18 birds caught in or obtained from Booderee National Park, Jervis Bay and Barren Grounds Nature Reserve, New South Wales. The study showed these birds largely take mobile terrestrial invertebrate species, the majority of which are ants and beetles. There is some indication that plant material, especially seeds, are also part of the diet. Observations suggest that the diet is opportunistic and based on foraging behaviour of 'peck it and see'. INTRODUCTION STUDY AREA AND METHODS Dasyornis brachypterus The specimens used in this study were obtained from two sites. The rare Eastern Bristlebird ° ° (Passeriformes: Pardalotidae), is a small, semi-flightless, Booderee National Park, (35 08'S, l 50 45'E) a Commonwealth of Australia owned area that occupies most of the Bherwerre brownish bird inhabiting low, dense vegetation in coastal Peninsula, on the southern side of Jervis Bay, on the south coast and near coastal south-eastern Australia. It once occurred of New South Wales and Barren Grounds Nature Reserve (34°40'S, in an almost continuous distribution from southern l 50 °42'E) on the lllawarra plateau, west of Kiama, New South Queensland to western Victoria (Baker 1997).

    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations.

Aust. 7 (1) : 153–178 (2008) Flora and Vegetation of the banded iron formations of the Yilgarn Craton: the Weld Range ADRIENNE S MARKEY AND STEVEN J DILLON Science Division, Department of Environment and Conservation, Wildlife Research Centre, PO Box 51, Wanneroo WA 6946. Email: [email protected] ABSTRACT A survey of the flora and floristic communities of the Weld Range, in the Murchison region of Western Australia, was undertaken using classification and ordination analysis of quadrat data. A total of 239 taxa (species, subspecies and varieties) and five hybrids of vascular plants were collected and identified from within the survey area. Of these, 229 taxa were native and 10 species were introduced. Eight priority species were located in this survey, six of these being new records for the Weld Range. Although no species endemic to the Weld Range were located in this survey, new populations of three priority listed taxa were identified which represent significant range extensions for these taxa of conservation significance. Eight floristic community types (six types, two of these subdivided into two subtypes each) were identified and described for the Weld Range, with the primary division in the classification separating a dolerite-associated floristic community from those on banded iron formation. Floristic communities occurring on BIF were found to be associated with topographic relief, underlying geology and soil chemistry. There did not appear to be any restricted communities within the landform, but some communities may be geographically restricted to the Weld Range. Because these communities on the Weld Range are so closely associated with topography and substrate, they are vulnerable to impact from mineral exploration and open cast mining.

    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.
