The Chief Scientist, Professor Peter Klinken, launched our Science Strategic Plan 2018-21 for the department in August 2018 and since then we have developed science plans for each of our 10 programs. These plans articulate how the work of each program contributes to delivery of the themes identified in the strategic plan. The science undertaken through the programs delivers against the biodiversity science priorities for the State and is essential to ensure we conserve and appreciate the unique biodiversity we have around us. In conjunction with our strategic planning we are continuing 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 welcomed new staff with expertise in forest science, structured decision-making, plant ecology and ecoinformatics. We have continued to deliver effective science to support the department’s functions. Highlights of our scientific research for this year include confirmation of eradication of feral cats from Dirk Hartog Island, development of a conceptual model of the hydrology of freshwater springs at Walyarta (80 Mile Beach Ramsar site), production of 900 seedlings of the spider orchid Caladenia busselliana for a translocation of this rare species, monitored the outbreak of the harmful algae Alexandrium spp. and determined toxin uptake in fish, crabs and mussels, development of spinifex cover measures from satellite imagery to inform prescribed burning activities, and analysis of data from a 30 year experimental study to understand how understorey plants in the jarrah forest respond to different combinations of fire interval and season. We have published the final report of the WAMSI Kimberley Marine Research Program, and published a book describing the red algae of Western Australia’s tropical coast. We also celebrated 50 years of forest research at the Manjimup Research Centre. Our staff in Species and Communities Program made important contributions to the Biodiversity Conservation Regulations gazetted in January 2019 to give effect to the Biodiversity Conservation Act 2016. We are working with regional staff and members of the community to implement new provisions supporting conservation of our plants, animals and ecosystems. As we consolidate after the major change of the past year, I am confident we will continue to deliver excellent science and remain active in pursuing opportunities and seeking innovative ways to underpin effective biodiversity conservation in Western Australia. We have continued 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. Much of our work is undertaken in partnership with conservation staff in the Parks and Wildlife Service, and at Kings Park and Botanic Garden, Perth Zoo and the Rottnest Island Authority. We also 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 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 conservation and management of our diverse and inspiring 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.

The offset proposal was approved by the Department of Environment and Conservation's (DEC) CEO on 30 November 2010 in accordance with conditions 5(a)(ii), 9(c) and Part V of cleahng permit CPS 818/5. The approved offset proposal sought to offset the proposed clearing of 1.023 hectares of native vegetation through the revegetation of 1.91 hectares in two disused roads (an old military road {UCL} and Clover Road {Gnangara-Moore River State Forest}) and a disused gravel pit within Gnangara-Moore River State Forest and a research plot within Yanchep National Park. MRWA is seeking an amended approval letter to change the current requirement for monitoring to occur monthly from September 2011 to August 2014 to monthly monitoring from September-November 2011, March-May 2012 and September-November 2012 only, followed by six-monthly monitoring, with annual reports submitted to DEC in August each year.

    Conservation Science W. 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.

  • Palatability of Plants to Camels (DBIRD NT)
    Technote No. 116 June 2003 Agdex No: 468/62 ISSN No: 0158-2755 The Palatability of Central Australian Plant Species to Camels Dr B. Dorges, Dr J. Heucke, Central Australian Camel Industry Association and R. Dance, Pastoral Division, Alice Springs BACKGROUND About 600,000 camels (Camelus dromedarius) are believed to inhabit the arid centre of Australia, mainly in South Australia, Western Australia and the Northern Territory. Most of these camels are feral. A small camel industry has developed, which harvests selected animals for domestic and export markets, primarily for meat. Camels can eat more than 80% of the common plant species found in Central Australia. Some plant species are actively sought by camels and may need to be protected. METHOD Observations of grazing preferences by camels were made periodically for up to 12 years on five cattle stations in Central Australia. Where camels were accustomed to the presence of humans, it was possible to observe their grazing preferences from a few metres. Radio transmitters were fitted on some camels for easy detection and observation at any time. These evaluations were used to establish a diet preference or palatability index for observed food plants. Table 1. Palatability index for camels Index Interpretation 1 only eaten when nothing else is available 2 rarely eaten 3 common food plant 4 main food plant at times 5 preferred food plant 6 highly preferred food plant 7 could be killed by camel browsing More information can be obtained from the web site of the Central Australian Camel Industry Association http://www.camelsaust.com.au 2 RESULTS Table 2.
