On 1 July 2017, the Department of Parks and Wildlife was amalgamated with the Botanic Gardens and Parks Authority, Zoological Parks Authority and Rottnest Island Authority. A key focus area for the new department, as identified by the State Government, is to combine biodiversity science into one department to build and share biodiversity knowledge. In that context, the science functions of the previous agencies have been combined in Biodiversity and Conservation Science and this report reflects the activities and outcomes of the science work of the new department for the past financial year. In forming Biodiversity and Conservation Science to provide science services to the whole of the department, we have established a new structure. Along with continuing the existing programs of Animal Science, Plant Science and Herbarium, Marine Science, Ecoinformatics, and Species and Communities, we have formed new programs in Fire Science, Kings Park Science, Perth Zoo Science, Remote Sensing and Spatial Analysis, and Rivers and Estuaries Science. The work undertaken in the previous Wetlands Conservation Program and the Biogeography Program has joined forestry research in the Ecosystem Science Program. A Biodiversity and Conservation Science Forum held in May showcased the diversity and high quality of science delivered by Biodiversity and Conservation Science, and provided an opportunity for staff and affiliated students to learn about the science projects undertaken. A key activity this year has been to prepare a Science Strategic Plan for the department. Development of the plan drew on the knowledge and expertise of a range of departmental staff from science, operations, management and policy, to determine the key direction for science to support the policy and operational conservation management functions of the department. The plan was endorsed by Corporate Executive in June and was launched by the Chief Scientist, Professor Peter Klinken, in August. The plan articulates the key objectives of science against five of the six strategic intent statements for the department: Biodiversity and Conservation, Fire Management, Natural and Cultural Values, Our Community and Partners, and Our People. The science plan also links with state science priorities, as Biodiversity and Marine Science is identified in A Science Statement for Western Australia as a priority area for science in Western Australia where scientific knowledge is essential to ensure we conserve, appreciate and value add to the unique biodiversity found around us. Throughout the changes and development of the strategic plan we have maintained our scientific research activity and outputs. Highlights for this year include a pilot translocation of hare wallabies to Dirk Hartog Island given the success in goat and cat eradication programs, the launch of the Banksia Woodlands Restoration book that is a culmination of many years research into restoration of Banksia Woodlands by scientists from Kings Park, flora translocation for species identified as a priority in the national Threatened Species Strategy, the completion of targeted surveys for rare flora and bilbies in the La Grange Irrigated Agriculture project area in the west Kimberley, and the discovery in Roebuck Bay of the first consistently used foraging area for flatback turtles. Species and Communities Branch staff have also provided considerable input to the drafting of Regulations to support the Biodiversity Conservation Act 2016. Most of our projects have been undertaken in partnership with conservation staff in the Parks and Wildlife Service, and from Perth Zoo and Kings Park, and with fantastic assistance from our volunteers. I look forward to continuing to consolidate our new structure and furthering the delivery of excellence in applied science to support the conservation management of our diverse plants, animals and ecosystems for the benefit of all Western Australians. We will have an ongoing focus on partnerships and will strive to build additional relationships with universities, the resources sector, aboriginal land managers and NGOs. We also have a renewed focus on science communication and looking for new ways to share inspiring stories and connect people with our fascinating plants and animals and our unique natural places is a key objective.

    Aerial diving display, with calling, by Black Falcon Falco subniger D.J. Whelan 24 Manning Boulevard, Darley VIC 3440, Australia Email: [email protected] Australian Field Ornithology 2014, 31, 43–49 Early South Australian records of the Western Grasswren Amytornis textilis myall Andrew B. Black South Australian Museum, North Terrace, Adelaide SA 5000, Australia Email: [email protected] Summary. Records show that the naturalist–collector F.W. Andrews provided five specimens of the Western Grasswren Amytornis textilis myall from the Gawler Ranges for the South Australian Museum, Adelaide (SAMA), in the 1870s, but there is evidence suggesting that he obtained others in that period. Two of these specimens are retained in the collection of the Institut royal des Sciences naturelles de Belgique, Brussels, Belgium, and one each in the Muséum national d’Histoire naturelle, Paris, France, and the Macleay Museum, Sydney. Four ‘Amytis textilis’ sent elsewhere have not been located recently and another two were evidently discarded from the SAMA around 1882. The first of the records that these specimens represent precedes the previously acknowledged earliest observations of the northern Eyre Peninsula– Gawler Ranges subspecies in 1902 by 31 years (Chenery 1903) and the recognition of their taxonomic status by 45 years (Mathews 1916). Introduction The first to publish a report of the Western Grasswren Amytornis textilis (Quoy & Gaimard, 1824) in South Australia (SA) was Chenery (1903) although he did not name it, simply listing it as ‘Amytis – (?)’. He and Morgan (1924) saw these grasswrens on Nonning and Mount Ive Stations, central Gawler Ranges, in August 1902 and took two specimens, which Morgan donated ~10 years later to the South Australian Museum, Adelaide (SAMA) (B7359 and B7360) (Zietz 1913).

Nicola Georgina Bergh Town Thesis presented for theCape Degree of DOCTOR OF ofPHILOSOPHY in the Department of Botany UNIVERSITY OF CAPE TOWN University May 2009 Town Cape of University ii ABSTRACT The Greater Cape Floristic Region (GCFR) houses a flora unique for its diversity and high endemicity. A large amount of the diversity is housed in just a few lineages, presumed to have radiated in the region. For many of these lineages there is no robust phylogenetic hypothesis of relationships, and few Cape plants have been examined for the spatial distribution of their population genetic variation. Such studies are especially relevant for the Cape where high rates of species diversification and the ongoing maintenance of species proliferation is hypothesised. Subtribe Relhaniinae of the daisy tribe Gnaphalieae is one such little-studied lineage. The taxonomic circumscription of this subtribe, the biogeography of its early diversification and its relationships to other members of the Gnaphalieae are elucidated by means of a dated phylogenetic hypothesis. Molecular DNA sequence data from both chloroplast and nuclear genomes are used to reconstruct evolutionary history using parsimony and Bayesian tools for phylogeny estimation.

Bates cl- State Herbarium of South Australia, Botanic Gardens of Adelaide, North Terrace, Adelaide, South Australia 5000 Abstract Microns eremaea, M graniticola and M media R.Br. ssp. eremicola are described as new; illustrations are provided together with a distribution map. Discussion of variation within each species and suspected hybrids is included. Introduction Bates (1984) recorded seven species of Microtis from Western Australia. Only M unifolia sensu lato was thought to occur in the dry inland. Later, Bates (1990) recognised ten Western Australian Microtis and identified three inland species which were treated as M media R.Br., M parvifolia R.Br. and M unifolia (Forst f.)Reichb.f. sens. lar. The type forms of M media, M parviflora and M unifolia are all plants of high rainfall coastal regions; M media ssp. media occurring in south-western Australia, M parviflora in eastern Australia and M unifolia in New Zealand. In view of the very different habitat requirements of plants from semi-arid Western Australia is seemed most unlikely they were the same taxa. The author spent time collecting Microtis in Western Australia in 1990 and after re-examining herbarium collections from PERTH and AD concluded that several undescribed taxa were involved, the three best known being here described as new.

    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.
