Degradation Of Remnant Vegetation, Richard George, Don Mcfarlane, Russell Speed

Journal of the Department of Agriculture, Western Australia, Series 4

Remnant vegetation, wetlands and riverine systems on both private and public land throughout south-western Australia are being rapidly degraded by dryland salinity, inundation, silting, nutrient enrichment and weed invasion. Richard George, Don McFarlane and Russel Speed outline some of the reasons why this is happening and provide some case studies that highlight actions to protect these remnants.


Toolibin Catchment Revegetation Manual, Avril Baxter Jan 1996

Toolibin Catchment Revegetation Manual, Avril Baxter

Natural resources published reports

In1983, heavy winter rains resulted in severe inundation and flooding of the lower parts of the Toolibin catchment. The damage to crops and pastures was immense and costly. Local farmers realised that they needed to work together to minimise the impact of heavy rainfall events on their farm productivity.

At the same time the Western Australian Department of Conservation and Land Management (CALM) was concerned about the quality of both ground and surface water in the catchment area for Toolibin Lake, the last remaining wooded freshwater lake in the southern wheatbelt. This mutual interest led to the formation of the …

Fish Health For Fish Farmers In Western Australia, Tina Thorne Oct 1995

Fish Health For Fish Farmers In Western Australia, Tina Thorne

Fisheries Published Reports

Disease is a departure from the normal state of health of a fish or any other animal. Diseases have no doubt occurred among fishes since these animals have occupied a place on the earth. Scientific efforts to understand the causes of disease in fishes, and to attempt to control them however, have only been made during the last sixty years.

Fishes, crustaceans and molluscs, as with other animals are subject to a wide spectrum of diseases, that can be classified as infectious or non-infectious. The vast majority of disease problems in the intensive farming of aquatic animals can be traced …

Effects Of Tactical Responses And Risk Aversion On Farm Wheat Supply, Ross S. Kingwell Apr 1995

Effects Of Tactical Responses And Risk Aversion On Farm Wheat Supply, Ross S. Kingwell

Natural Resources Research Articles

A discrete stochastic programming model of the farming system of the eastern wheatbelt of Western Australia is used to examine the effect of tactical responses and risk aversion on wheat supply. Including within-season tactical changes to wheat areas decreases the own-price elasticity of supply. By contrast, introducing risk aversion has no consistent effect on the own-price elasticity of supply. The implications for supply models are discussed.


Buntine-West Wubin And West Maya Catchment Management Report, William Oldfield, Natalie Hunt Mar 1995

Buntine-West Wubin And West Maya Catchment Management Report, William Oldfield, Natalie Hunt

Natural resources published reports

Buntine West/Wubin land Conservation District was formed when a number of landholders wanted to extend and join on to some existing deep drains. At first the group concentrated on the deep drains with some farmers joining on anda project to connect the drains up througha naturally occurring saline area and to run the main drain into a salt lake system. Funding was attained for 50% of the project and farmers with drains paid for the rest. It was considered unfair for landowners whose land this drain went through to pay all the cost as it was not draining arable land. …

Reading The Rangeland: A Guide To The Arid Shrublands Of Western Australia, Don Burnside, Alec Holm, Alan Payne, Georgina Wilson

All other publications

Managing the rangelands is complex. Soils and vegetation can vary considerably over short distances in distinct or subtle ways. Separating climatic from management influences on the condition of the land has always been difficult. Whether we live on a sheep station, in a country town, in an Aboriginal community, a mining camp, or even if we only visit the Australian outback, it is vital that we understand and appreciate the unique character and management requirements of the rangelands. Learning to ‘read the rangeland’ has been a slow process, involving the knowledge and skills of pastoralists, Aboriginal people and scientists. This …

A Guide To Floodplain Cattle Fencing, Department Of Agriculture, Western Australia, Main Roads, Western Australia

Animal production and livestock published reports

A seminar and workshop was held at Fitzroy Crossing in October 1993 to address the consequences of flooding to landholders and communities.

Damage to flood plain fencing was identified as one of the major concerns to landholders.

An outcome from the workshop was the decision to draw on local knowledge and collate information on options for fence and floodgate designs.

This information was to be made available to land holders and other interested parties - hence this publication.

Bulletin 4279 - Streamlining - An Environmentally Sustainable Drainage Network For The Swan Coastal Plain (Peel-Harvey Catchment), Garry Heady, Neil Guise

Bulletins 4000 -

Community Catchment Centre Pinjarra

A network of over 1400 kilometres of drains and modified natural waterways constructed by the Public Works Department criss-crosses the Peel-Harvey catchment. There are also over 3300 kilometres of minor drains and natural waterways in this same region.

The expansion of agriculture relied on this extensive drainage network, which was designed to ensure rapid drainage of the region. Unfortunately there was little regard to future environmental consequences.

Along with drainage water, these same drains now carry high loads of silt and nutrients. Many of the drains are also degraded and require expensive maintenance annually.


Should Australia Export Its Native Birds?, Ross Kingwell Aug 1994

Should Australia Export Its Native Birds?, Ross Kingwell

Biosecurity Research Articles

Commercial export from Australia of native birds, wild or captive bred, is prohibited. This paper firstly describes the current legislation and regulations that restrict the export of native birds and discusses why governments have adopted such a regulatory approach to bird species preservation. Secondly, the paper reviews the debate concerning the export ban, pointing out strengths and weaknesses in arguments and indicating the important role of CITES. Lastly, the paper outlines a new case for a conditional lifting of the ban, whereby DNA fingerprinting is used to establish transferable property rights to overcome a main source of market failure in …


Bulletin 4283 - Nitrogen Fertilisers For Cereal Production, M. G. Mason Mar 1994

Bulletin 4283 - Nitrogen Fertilisers For Cereal Production, M. G. Mason

Bulletins 4000 -

Because fertiliser prices are high, it is important to understand what affects the response to fertilisers by crops.

Among the many factors influencing crop response to nitrogen applications, the most important are the season, soil type, paddock history, time of application and source of nitrogen. Before deciding whether to use nitrogen on a cereal crop, which source to use and at what rate, you need some understanding of how these factors work.

Greatest responses to nitrogen fertilisers can be expected in areas with a relatively long growing season. In such areas light soils with a low nitrogen status give the …
