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.

Dealing With A Dry Season, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Farmers' approaches to adverse seasonal conditions whether they be frost, flood or low rainfall should be to acquire as much information as possible on the immediate agronomic and financial situations and make a judgement on the longer term implications for the following seasons. Once the information has been acquired, in consultation with advisers, it is necessary to construct and implement agronomic and business strategies to deal with individual situations.

The agronomic and stocking options for the dry season supplied in this booklet deal with questions and issues arising from the Year 2000 season, which has been characterised by a mid …

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 …

Catchment Water Management: Guidelines For Those Considering Drainage For Waterlogging And Salinity Management, Department Of Agriculture And Food, Western Australia, Water And Rivers Commission, State Salinity Council

Bulletins 4000 -

Landholder groups and government agencies are continuing to develop "best drainage practice" guidelines and these will increase our knowledge of drainage, and deep drainage in particular, as a management tool. The brochure does not provide all the answers, but is intended to provide some basic information to assist landholders who may be considering some form of water management or drainage systems.

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.

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

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 …

Stocking Rate Guidelines For Rural Small Holdings, Swan Coastal Plain And Darling Scarp And Surrounds, Western Australia, Dennis Van Gool, Ken Angell, Lindsay Stephens

Agriculture reports

Small rural holdings are often owned by people who want to pursue a semi-rural lifestyle but who are inexperienced in land management issues. This can result in landholders stocking their properties with animals at rates higher than the land resources can sustain, leading to degradation problems such as soil erosion, water pollution and damage to vegetation. This document provides information and guidelines to help planners, developers, local authorities and land owners determine the base stocking rates for rural small holdings on the Swan Coastal Plain and Darling Scarp and immediate surrounds. The advice utilises Agriculture Western Australia’s rural stocking rate …

Western Australia Soil Acidity Research And Development Update 2000 : Time To Lime, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

We have come a long way over the past three or four years in terms of both, the level of understanding and recognition of Soil Acidity as a major land degradation issue for the wheatbelt of Western Australia, and, in our actions to treat the problem.

During 1999 there were three very significant changes relating to acid soils in Western Australia.

• Lime use in WA increased by over 200,000 tonnes from 1998 to 1999 to a record 653,000 tonnes, which was double the amount applied in 1997.
• The Agricultural Lime Industry adopted a voluntary Lime Industry Code of Practice in …

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.

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 …
