Predicted Land Use Changes In Agricultural Areas Of Wa And Resulting Impact On The Extent Of Dryland Salinity, C E. Mcconnell
Predicted Land Use Changes In Agricultural Areas Of Wa And Resulting Impact On The Extent Of Dryland Salinity, C E. Mcconnell
Resource management technical reports
An assessment of current and possible future land use in Western Australia was undertaken as part of the National Land and Water Resources Audit. This data was used to assess the impact of land use change on the future extent of salinity. It was found that in some areas there is real capacity for changing land use to impact on recharge to the watertable.
The Aquaculture Of Non-Endemic Species In Western Australia Silver Perch (Bidyanus Bidyanus), Tina Thorne, H. G. Brayford
The Aquaculture Of Non-Endemic Species In Western Australia Silver Perch (Bidyanus Bidyanus), Tina Thorne, H. G. Brayford
Fisheries management papers
The development of commercial aquaculture of a non-endemic species such as silver perch raises a number of important issues relating to translocation. These include the potential of the introduced species to: impact on genetic diversity; introduce disease; and impact on - the natural environment; and - the biodiversity of native species. This Management Paper has been drafted in liaison with the Department of Environmental Protection in accordance with the principles of rish assessment, taking into account the above issues. It is considered that the implementation of this policy will protect the natural environment and native fish species. It will also …
Aquaculture Plan For The Recherche Archipelago, Fisheries Western Australia.
Aquaculture Plan For The Recherche Archipelago, Fisheries Western Australia.
Fisheries management papers
Land supply and land cost for aquaculture may become a limiting factor in the foreseeable future. At present, adequate appropriately zoned land is available at reasonable cost. The most prospective land for aquaculture in or near Esperance is where suitable zoned land occurs over saline ground water aquifers or adjacent to the coast. Careful site selection would be necessary to ensure water supply, waste water disposal, services and operational space can be achieved at reasonable cost.

These guidelines apply to the management of Western Australia piggeries in Western Australia, including intensive Growing pigs under intensive conditions where the and extensive operations, straw-based housing and animals spend their entire life cycle indoors, is an combinations of these (otherwise referred to as semi- important part of the Western Australian and intensive housing).
The Rural Towns Program : Groundwater Modelling : The Merredin Catchment, J Matta
The Rural Towns Program : Groundwater Modelling : The Merredin Catchment, J Matta
Resource management technical reports
Agriculture Western Australia (Agwest), as part of the Rural Towns Program, was engaged to test the application of a groundwater model for potential future management options against salinity for the Merredin townsite. This report illustrates some of the options that could be implemented to achieve the objective of salinity management.
A Conceptual Hydrogeological Model For The Lake Warden Recovery Catchments Esperance, Western Australia, R Short
Resource management technical reports
The National Land and Water Resource Audit (NLWRA), has identified Dryland Salinity as one of seven major themes for an audit of the nation’s land, water, vegetation and natural resource management. Within this theme, Project 3 has been developed to investigate a key catchment type and how management scenarios will impact on dryland salinity processes. The Lake Warden catchments have been chosen as one of four catchment water balance studies to be undertaken nationally. The catchment water balance analysis will be undertaken using numerical modelling by the CSIRO, Division of Land and Water.
Aquaculture Plan For The Houtman Abrolhos Islands, Fisheries Western Australia
Aquaculture Plan For The Houtman Abrolhos Islands, Fisheries Western Australia
Fisheries management papers
The objective of this aquaculture plan is to : Provide a sound basis for developing a new aquaculture industry in the Abrolhos Islands, while at the same time conserving the unique environment of the islands for present and future generations, and minimising conflict between aquaculture and existing and future users of the islands.

Protecting And Sharing Western Australia's Coastal Fish Resources. The Path To Integrated Management., Fisheries Western Australia
Fisheries management papers
The fisheries management framework of the 21st Century must not only be able to manage the level of exploitation by commercial and recreational fisheries, but also provide an agreed basis and process for changes in the way fish and aquatic resources are used and shared by this community. There is a clear need to counter inevitable pressure on stocks from the impact of a growing population, increasing coastal development and the demands of various key user groups. Unless we are proactive in dealing with the growing exploitation of fisheries along our State’s vast 12,000km coastline, it will be difficult to …
Wetland Vegetation Monitoring, 1999/2000 (Salinity Action Plan), R. Gurner, R. Froend, G. Ogden, B. Franke
Wetland Vegetation Monitoring, 1999/2000 (Salinity Action Plan), R. Gurner, R. Froend, G. Ogden, B. Franke
Research outputs pre 2011
This report represents the vegetation component of a project designed to provide on-going monitoring of wetland salinity and biological resources in wetlands of the agricultural zone of south-west Western Australia. Maintenance of wetland biological diversity in the agricultural zone is one of the major objectives of the Salinity Action Plan. Due to their low position in the landscape, wetlands are the habitat most affected by salinisation.

Katanning Area Land Resources Survey, Heather M. Percy, G M. Wilson, Ted A. Griffin
Land resources series
This report presents results from soil and landform mapping at a scale of 1:150,000 in the Katanning area of Western Australia. It is accompanied by two soil-landscape maps covering 1.45 million hectares in the Kojonup and Darkan area (map 1) and the Katanning and Dumbleyung area (map 2). Most of the Katanning survey occurs within the Blackwood River catchment but also covers the upper catchments of the Pallinup, Frankland-Gordon and Tone-Warren Rivers. The Katanning survey falls within the Narrogin and Katanning advisory districts for Agriculture Western Australia. Twenty one soil-landscape systems have been identified and are represented on the accompanying …

Managing The Acidity Of Abandoned Water Filled Coal Mining Voids In Collie (Western Australia) Using Organic Matter, Scott A. Thompson
Managing The Acidity Of Abandoned Water Filled Coal Mining Voids In Collie (Western Australia) Using Organic Matter, Scott A. Thompson
Theses: Doctorates and Masters
The effectiveness of using organic matter additions to increase pH in abandoned water filled coal mining voids in Collie was investigated. Previous studies have demonstrated that passing acidic drainage through organic matter increased the waters pH. Laboratory trials using intact sediment cores (collected from Ewington, Collie, Western Australia) were used to assess the effects of additions of hay, manure and mulched vegetation on pH, nutrients an sulphate levels. In a series of experiments the effect of different quantities of organic material, sulphate reducing bacterial inoculations and alkalinity generation were measured. A subsequent field experiment was conducted to examine the impact …
