Upper Yilgarn Catchment Appraisal 2005, Keith Ohlsen, Susan Murphy-White
Upper Yilgarn Catchment Appraisal 2005, Keith Ohlsen, Susan Murphy-White
Resource management technical reports
Soil degradation on farmland reduces agricultural production and will often lead to damage to natural resources such as remnant vegetation and waterways, as well as to infrastructure, including roads and townsites. This report provides current information on the land degradation status for the Upper Yilgarn Catchment area in Western Australia by outlining: condition of the soils, hydrology, natural vegetation, farming systems and agricultural production and risks to natural resources.
A Salt On The Land: The Osmolyte Production And Physiological Responses Of Selected Myrtaceae Species Exposed To Salt And Water Stress, Janelle Atkinson
A Salt On The Land: The Osmolyte Production And Physiological Responses Of Selected Myrtaceae Species Exposed To Salt And Water Stress, Janelle Atkinson
Theses: Doctorates and Masters
Glasshouse trials were conducted on Calothamnus quadrifidus, Eucalyptus camaldulensis and Melaleuca uncinata
to test relative tolerance and uniformity of response in the Myrtaceae family to salt, waterlogging and salt x waterlogging. Seed sources from both saline (SA) and non-saline areas were used to compare differences in survival, growth and proline production to these stresses.

Resource management technical reports
This report provides an assessment of two large deep drainage schemes within the lower reaches of the Bodallin and Elachbutting Catchments nearby Merredin in Western Australia, wherein groups of isolated wetland basins have been utilised for evaporative saline drainage water disposal. In both cases, the storage capacity of the basins has been exceeded, leading to flooding and death of the surrounding native vegetation.

Future Mangement Arrangements For Western Australia's Temperate Shark Fisheries., Jane Borg, R. Mcauley
Future Mangement Arrangements For Western Australia's Temperate Shark Fisheries., Jane Borg, R. Mcauley
Fisheries management papers
This paper provides a summary of the attributes of these temperate shark fisheries, and sets out the proposed objectives and the measures available to achieve them. In summary, primary measures are aimed at the sustainability of dusky and whiskery sharks, with dusky sharks being of greater concern as their status is more critical. The final decision on management of these fisheries cannot compromise sustainability, not only because of the Department’s obligations under the Fish Resources Management Act, 1994, but also: • national and international obligations associated with ecologically sustainable development; • export accreditation under the Environmental Protection and Biodiversity Conservation …

Proposals For Community Discussion - A Quality Future For Recreational Fishing In The South Coast. A Five-Year Strategy For Managing The Recreational Component Of The Catch., South Coast Recreational Fishing Working Group.
Fisheries management papers
With a growing population and advances in technology, fishing pressure will continue to grow and anglers will become more efficient at targeting fish, particularly offshore demersal species such as blue groper, dhufish, red snapper, breaksea cod and queen snapper. There is also a clear need for recreational fisheries management to complement the existing management arrangements for the charter industry, and provide the necessary framework for recreational fishing to be incorporated into an integrated management framework with other fishing sectors.

Draft Aquaculture Plan For Shark Bay., Department Of Fisheries
Draft Aquaculture Plan For Shark Bay., Department Of Fisheries
Fisheries management papers
The Department of Fisheries has prepared this draft aquaculture plan for Shark Bay to provide an agreed framework for future management of aquaculture. The final plan will assist prospective aquaculturists in preparing proposals and will guide the Department of Fisheries in the decision making process for aquaculture licence and lease applications. The plan identifies constraints to aquaculture development and areas where aquaculture may occur. It also identifies species that may be used for aquaculture development. Implementation of this plan will ensure that aquaculture can occur in a sustainable manner, while retaining the unique features of Shark Bay.
Fish Stock And Fishery Enhancement In Western Australia. A Summary Report., Department Of Fisheries
Fish Stock And Fishery Enhancement In Western Australia. A Summary Report., Department Of Fisheries
Fisheries management papers
This summary paper provides an overview of the key proposals set out in the full policy discussion paper, Fisheries Management Paper No 175. It does not discuss the theoretical background for the framework presented and therefore readers interested in such discussion are directed to Fisheries Management Paper No 175.
Both papers have been prepared to encourage public involvement in the development of policy for stock enhancement within Western Australian waters. Stock enhancement can involve an existing fishery or creation of a new fishery through the translocation of fish. It affects both public and private waters.

Productive agriculture increases the concentration of hydrogen ions in soil, which acidifies the soil.
Aluminium is a component of many soil constituents, including clays and oxides, and is also present on the surfaces of soil organic matter. As the concentration of hydrogen ions in soil increases, soil pH decreases, and aluminium starts to dissolve from the soil constituents, increasing the concentration of aluminium ions in soil solution.
As the concentration of aluminium ions in the solution increases, the aluminium in the soil solution becomes increasingly toxic to plant roots, reducing root growth. The smaller amounts of plant roots explore a …
Narrogin Townsite Test Pumping Results 2003, Louise Hopgood
Narrogin Townsite Test Pumping Results 2003, Louise Hopgood
Resource management technical reports
Test pumping of a production bore in Narrogin took place for 24 hours in August 2003. Data generated by the test pumping was analysed along with groundwater monitoring, climate and geological data. Laboratory analyses of water samples from the production bore indicate very high levels of salinity and hardness which may lead to severe scaling and corrosion of pumps, pipes and pipe fittings.

Spectacular Recovery In The Ord River Catchment, A L. Payne, I W. Watson, P E. Novelly
Agriculture reports
Regeneration work on severely damaged country in what is now known as the Ord River Regeneration Reserve (ORRR) commenced in 1960. The ORRR is in the East Kimberley area of Western Australia with an associated small area in the Northern Territory. The work included strip contour cultivation and seeding (which proceeded at various levels of intensity during the 1960s, 1970s and 1980s), fencing and destocking of cattle by mustering over many years, and the eradication of donkeys.

Kellerberrin Townsite Test Pumping Results 2003, Louise Hopgood
Kellerberrin Townsite Test Pumping Results 2003, Louise Hopgood
Resource management technical reports
A production bore in Kellerberrin, Western Australia, was test pumped for 24 hours in August 2003. Data generated by the pumping were analysed with groundwater monitoring, climate and geological data. Laboratory analyses of water samples from the production bore indicate a low pH and very high levels of salinity, hardness, sodium, chloride, iron, sulphate, aluminium and manganese. This is likely to lead to scaling, blockages, staining and/or corrosion of pumps, pipes and pipe fittings.
