The Crystal Chemistry Of Holtite, L. A. Groat, Edward S. Grew, R. J. Evans, A. Pieczka, T. S. Ercit

Earth Science Faculty Scholarship

Holtite, approximately (Al,Ta,square)Al(6)(BO(3))(Si,Sb(3+),As(3+))(Sigma 3)O(12)(O,OH,square)(Sigma 3), is a member of the dumortierite group that has been found in pegmatite, or alluvial deposits derived from pegmatite, at three localities: Greenbushes, Western Australia; Voron'i Tundry, Kola Peninsula, Russia; and Szklary, Lower Silesia, Poland. Holtite can contain >30 wt.% Sb(2)O(3), As(2)O(3), Ta(2)O(5), Nb(2)O(5), and TiO(2) (taken together), but none of these constituents is dominant at a crystallographic site, which raises the question whether this mineral is distinct from dumortierite. The crystal structures of four samples from the three localities have been refined to R(1) = 0.02-0.05. The results show dominantly: Al, Ta, and vacancies …

Five Year Management Strategy For The Recreational Trout Fishery. Discussion Paper For Public Comment On Future Management., The Rfac’S Recreational Freshwater Fisheries Stakeholder Sub-Committee

Fisheries management papers

The Recreational Fishing Advisory Committee (RFAC) was concerned over the delay in time in progressing this issue and recommended that the issue of trout stocking for recreational purposes be progressed in isolation. This matter was referred to the Recreational Freshwater Fisheries Stakeholder Sub-Committee (RFFSS) to progress the recreational aspects of stocking trout within State public waters. This strategy represents a significant step in ensuring the appropriate level of management is provided for the translocation of trout into and within Western Australia for recreational purposes. It is also hoped that this policy will serve as a guide for the management and …

Esperance Area Acid Sulfate Soil Hazard Mapping, Paul Galloway, Simon Clarendon

Resource management technical reports

This project created a regional scale (1:100 000) acid sulfate soil (ASS) hazard map for the Lake Warden and Esperance town areas, using a combination of existing soil-landscape mapping information and elevation data, supported by field observations and laboratory data from 18 soil cores and 29 additional borelogs with descriptive information useful for identifying ASS and potential ASS materials. All data gathered during this project used common standards and protocols developed in Australia for identifying and mapping ASS materials. The project extends the mapping for acid sulfate soil in the region, complementing existing maps compiled for other parts of the …

Preparing For A Changing And Variable Climate, Glynn Ward

Research Reports

Climate change has the potential to reshape the Australian wine industry. Regions will be differentially impacted and will respond according to their unique viticultural, environmental, economic and social characteristics. An industry forum and regional workshop series was held in Western Australia focusing on three wine regions: Margaret River, Pemberton and Mount Barker. Fine scale climate information (mesoscale maps) and overviews of current and emerging technologies and resources that can be used by the wine industry to plan for and manage the risks and opportunities resulting from a changing and variable climate were presented. The information indicated that the wine regions …

Integrated Fisheries Management. Allocation Report Roe's Abalone Resource Perth Metropolitan Region., Integrated Fisheries Allocation Advisory Committee

Fisheries management papers

The introduction of Integrated Fisheries Management (IFM) is a recent development in the management of fisheries in Western Australia. IFM is an initiative aimed at addressing the issue of how fish resources in Western Australia can be best shared between competing users within the broad context of “Ecologically Sustainable Development”, or ESD.

Benchmarking Biodiversity: Land Resource Mapping In The Ord River Catchment., Tricia Handasyde, Peter J. Tille, Noel R. Schoknecht, Karen Carnes

All other publications

This 2009 report describes the mapping of landform, vegetation and soils undertaken in the Ord River Catchment in the East Kimberley of Western Australia in order to provide a basis for biodiversity benchmarking. The project: • brought together and standardised existing Ord River catchment land resource mapping held by the Department of Agriculture and Food (DAFWA) and Department of Environment and Conservation (DEC) in a format compatible with adjoining mapping in the Northern Territory • mapped to land unit level an additional 4400 sq km of the Ord River catchment. • re-digitised 2200 sq km of vegetation mapping previously not …

Prawn Aquaculture In Western Australia. Final Esd Risk Assessment Report For Prawn Aquaculture., Department Of Fisheries Western Australia

Fisheries management papers

The Western Australian Department of Fisheries is responsible for the management of aquaculture in WA and is committed to implementing ESD. These principles are contained within the objectives of the Fish Resources Management Act 1994 and the Department is keen to demonstrate both to the Government and the broader community that these principles are being achieved. The Department developed a policy statement in 2002 - Policy for the Implementation of Ecologically Sustainable Development for Fisheries and Aquaculture within Western Australia - (Fletcher 2002) that described its direction to the Department on incorporating ESD within fisheries and aquaculture management.

An Inventory And Condition Survey Of The Lower Murchison River Area, Western Australia, P Hennig

Technical Bulletins

The inventory and condition survey of the lower Murchison River area, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 2002 and 2003, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. This survey report presents …
