Science Division Annual Research Activity Report 2011–2012 Department of Environment and Conservation Science Division annual research activity report and management implications 2011–2012 DIRECTOR'S MESSAGE Science Division undertakes scientific research for the effective conservation and management of Western Australian biodiversity and to increase knowledge in astronomy. We generate knowledge and understanding of the flora and fauna, the biological communities and landscapes in which they occur, and the ecosystem processes that support them. It is important to take stock periodically to determine how effective we are in achieving our goals. In early 2012 the Science Management Team undertook an evaluation of the outcomes of the science and research undertaken in the Programs and Units of the Division, and identified the strengths, weaknesses and areas for future development as a basis for ongoing strategic planning. The review of key outcomes demonstrated many significant achievements over the past five years, and significant new directions in the development of marine and climate change research. The Marine Science Program was established in 2006 and has grown substantially from a small base of four staff to a flourishing group of 20 active scientists. A statewide marine monitoring, evaluation and reporting program has been developed to facilitate and promote efficiency and effectiveness of marine protected areas. Research has supported monitoring and management programs with marine baseline information, methodological assessments and evaluation of key pressures and processes. Research into the vulnerability and adaptation of the biota to climate change gained greater focus through the establishment of the Biodiversity and Climate Change Unit in 2008, and we now have six projects specifically addressing climate-related research, along with numerous others that have a climate response component. NatureMap, one of the Division's flagship online data information portals, was launched in 2008 and has flourished to be a comprehensive source of data on Western Australian biodiversity that is widely used to support risk assessment, conservation planning and science-based decisions. Major biological surveys of the Pilbara IBRA region and selected Kimberley islands have been completed. Results of both surveys are being made available online as papers published in the Records of the Western Australian Museum Supplement. Targeted surveys of the Banded Iron Ranges have been undertaken and data are accessible through themed pages in NatureMap. These, and other targeted surveys of terrestrial and aquatic environments, have identified many new species and/or significant range expansions of species, including those that are locally endemic, rare and/or threatened. The forest monitoring project FORESTCHECK has concluded two rounds of monitoring on a five-year cycle and analysis of the first round of monitoring on 48 grids was published in a special issue of Australian Forestry in December 2011. The results of this program have been used in the development of the draft Forest Management Plan 2014–2023. Forest stream monitoring has demonstrated little effect of harvesting on stream salinity but has shown that some streams have low invertebrate diversity that is partly attributable to declining rainfall. A major study of forest fire behaviour has resulted in the development of a new fire behaviour prediction model that improves the reliability of predictions across a wide range of fire danger conditions. Seed conservation and translocation activities have led to achievement of the Target 8 of the Global strategy for Plant Conservation (2002–2010) of 70% (60% target) of the Western Australian threatened flora in ex-situ conservation and 13% (10% target) used in translocations. More than 70,000 specimens were added to the Western Australian Herbarium plant specimen collection, and the collection of over 700,000 specimens was moved to new facilities in the Western Australian Conservation Science Centre in 2011. Taxonomic research at the Herbarium has led to the discovery and description of 565 new taxa in the past five years, and over half of these are rare or priority taxa of conservation concern. Integrated genetic and ecological research has identified recommendations for management of small populations and remnant vegetation and design of restoration programs that will facilitate maintenance of species and landscape processes. Phytophthora infection is a major threat to flora in the south-west and research has identified novel control and eradication techniques that have been trialed at key sites in the Fitzgerald River National Park. Restoration of a major rangelands ecosystem is being achieved at Lorna Glen, a former pastoral lease, through removal of domesticated animals, establishment of fire regimes that produce a habitat mosaic and control of introduced predators. Native fauna assemblages are being reconstructed through translocations from Barrow Island and other sites, and from captive breeding facilities. Translocations 1 of our most threatened mammal, Gilbert‘s potoroo, to a secure site has led to a significant increase in numbers. Study of interactions between predators has confirmed a mesopredator release, where cats have become significant predators once foxes are reduced in abundance through baiting programs. Eradication of cats and rats is becoming a potential reality with the successful eradication of black rats on Direction Island in the Cocos (Keeling) group. The Perth Observatory had a significant achievement in being authors on a paper in the prestigious journal Nature. The Observatory contributed six years of observations to the analysis that concluded extrasolar planets outnumber stars in the Milky Way Galaxy. It is a professional obligation of scientists to communicate research findings to a range of audiences, and the reputation of both individual scientists and their institutions is largely built on the quality and quantity of published scientific work. Scientific publications in peer-reviewed journals validate the rigour of the science undertaken in the Division, and communication of the implications of the research to managers and operational staff through technical articles and general publications is also an important means of knowledge transfer. A review of productivity through written communications for the five years from July 2006 to June 2011 identified a significant increase in the rate of scientific publications by staff in the Division. From 2006 to 2011, the Division produced 574 scientific publications (papers, book chapters and books) and 1,376 general publications (conference publications, popular articles, reports, information sheets, etc). This represents an increase of 69% for scientific publications and 86% for general publications compared to the five years from 2001 to 2006. Communication of scientific outcomes and knowledge continues to be a key performance indicator for scientists and the Division to demonstrate effective translation of scientific research into knowledge as a basis for decision making and on-ground management. The scientific work of the Division that has led to the achievements made over the past five years would not be possible without the efficient support of the administrative staff, the work centre managers and library staff. I thank them for their ongoing dedication to supporting the work of the scientific staff. This year‘s activity report has been produced through a newly developed online project management system developed by the Science Applications Unit that has greatly increased the efficiency with which the report is produced. The requirement for scientific information is increasing and, given our finite capacity to meet this challenge, we need to continually review our approach and identify innovative and efficient ways of delivering best-practice science to meet the conservation needs of DEC. The Division has demonstrated many significant achievements over the past five years of which I have only been able to highlight a few. I look forward to ongoing scientific advancements to support biodiversity conservation in Western Australia.

The pandemic has made essential self distancing and quarantining to arrest the spread of the Corona virus. As a result, most APS activities have been shelved for the time being. Being in isolation at home has been a mixed blessing.

  • Genetic Connectivity and Diversity in Inselberg Populations of Acacia Woodmaniorum, a Rare Endemic of the Yilgarn Craton Banded Iron Formations
    Heredity (2013) 111, 437–444 & 2013 Macmillan Publishers Limited All rights reserved 0018-067X/13 www.nature.com/hdy ORIGINAL ARTICLE Genetic connectivity and diversity in inselberg populations of Acacia woodmaniorum, a rare endemic of the Yilgarn Craton banded iron formations MA Millar, DJ Coates and M Byrne Historically rare plant species with disjunct population distributions and small population sizes might be expected to show significant genetic structure and low levels of genetic diversity because of the effects of inbreeding and genetic drift. Across the globe, terrestrial inselbergs are habitat for rich, often rare and endemic flora and are valuable systems for investigating evolutionary processes that shape patterns of genetic structure and levels of genetic diversity at the landscape scale. We assessed genetic structure and levels of genetic diversity across the range of the historically rare inselberg endemic Acacia woodmaniorum. Phylogeographic and genetic structure indicates that connectivity is not sufficient to produce a panmictic population across the limited geographic range of the species. However, historical levels of gene flow are sufficient to maintain a high degree of adaptive connectivity across the landscape. Genetic diversity indicates gene flow is sufficient to largely counteract any negative genetic effects of inbreeding and random genetic drift in even the most disjunct or smallest populations. Phylogeographic and genetic structure, a signal of isolation by distance and a lack of evidence of recent genetic bottlenecks suggest long-term stability of contemporary population distributions and population sizes. There is some evidence that genetic connectivity among disjunct outcrops may be facilitated by the occasional long distance dispersal of Acacia polyads carried by insect pollinators moved by prevailing winds.

Acacia longifolia is an aggressive invader worldwide. This species was brought to Portugal by the forestry services and is now found throughout the country with very strong ecological and social impacts. Al- though several ecological and physiological studies have been carried out, molecular studies in this species are sparse. Particularly, genetic variability evaluation in invasive ranges clearly deserves more attention. The aim of this study was to evaluate the genetic diversity and the genetic differentiation among populations of the alien in- vasive A. longifolia under different Mediterranean conditions. For that we studied three sandy dune populations along the Portuguese coast: Osso da Baleia (mesomediterranean), Pinheiro da Cruz and Vila Nova de Milfontes (termomediterranean). All sampled acacia plants were located underneath a pine forest, with the exception of the latter case study, where we also sampled in a diversified habitat conditions associated with the margins of agriculture fields.

  • Rare Or Threatened Vascular Plant Species of Wollemi National Park, Central Eastern New South Wales
    Rare or threatened vascular plant species of Wollemi National Park, central eastern New South Wales. Stephen A.J. Bell Eastcoast Flora Survey PO Box 216 Kotara Fair, NSW 2289, AUSTRALIA Abstract: Wollemi National Park (c. 32o 20’– 33o 30’S, 150o– 151oE), approximately 100 km north-west of Sydney, conserves over 500 000 ha of the Triassic sandstone environments of the Central Coast and Tablelands of New South Wales, and occupies approximately 25% of the Sydney Basin biogeographical region. 94 taxa of conservation signiicance have been recorded and Wollemi is recognised as an important reservoir of rare and uncommon plant taxa, conserving more than 20% of all listed threatened species for the Central Coast, Central Tablelands and Central Western Slopes botanical divisions. For a land area occupying only 0.05% of these divisions, Wollemi is of paramount importance in regional conservation. Surveys within Wollemi National Park over the last decade have recorded several new populations of signiicant vascular plant species, including some sizeable range extensions. This paper summarises the current status of all rare or threatened taxa, describes habitat and associated species for many of these and proposes IUCN (2001) codes for all, as well as suggesting revisions to current conservation risk codes for some species. For Wollemi National Park 37 species are currently listed as Endangered (15 species) or Vulnerable (22 species) under the New South Wales Threatened Species Conservation Act 1995. An additional 50 species are currently listed as nationally rare under the Briggs and Leigh (1996) classiication, or have been suggested as such by various workers. Seven species are awaiting further taxonomic investigation, including Eucalyptus sp.

    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.
