Observations Of Shallow Groundwater Contamination Due To Leakage Of Dairy Effluent Ponds On The Swan Coastal Plain, Wa, Richard J. George Dr, D L. Bennett, J R M Bell, Roger Wrigley

Resource management technical reports

In response to the risk of pollution of surface water from farm runoff, dairy farmers have been encouraged to install effluent storage ponds. Previous research has indicated that leachate from these storages can contribute to groundwater contamination. This project assessed the performance of storages at eight sites on the Swan Coastal Plain (SCP), WA. Groundwater conditions were monitored for over three years to study the influence of soil type, water table depth and waste water characteristics.

An Assessment Of The Impact Of Ophthalmia Dam On The Floodplains Of The Fortescue River On Ethel Creek And Roy Hill Stations, A L. Payne, A A. Mitchell

Resource management technical reports

The area surveyed covered all of the floodplains of the Fortescue River, and Jigalong, Jimblebar and Carramulla Creeks which fall within Ethel Creek and Roy Hill stations. Two serious, distinct and largely unrelated environmental problems are evident on the area surveyed. The first problem is longstanding, severe landscape degradation in the form of almost complete loss of perennial vegetative cover and soil erosion (mainly scalding) due to historical overgrazing.

The Translocation Of Barramundi. A Discussion Paper., Makaira Pty Ltd

Fisheries management papers

There is recognisable economic benefit to the translocation of barramundi, but there is also a need to ensure the translocation will not adversely impact upon the genetic diversity, introduce disease or impact on the natural environment and biodiversity. This discussion paper has been prepared to provide information to assist in the assessment of the possible impact of translocation of barramundi into and within Western Australia, for the purposed of recreational stock enhancement, aquaculture development and domestic stocking. In contemplating the translocation any aquatic species, signigicant economic and social benefits must be balanced with biological and environmental risks; that is, the …

Proposals For Community Discussion. A Quality Future For Recreational Fishing In The Gascoyne. A Five-Year Management Strategy For Recreational Fishing., Gascoyne Recreational Fishing Working Group

Fisheries management papers

Gascoyne has seen a series of rapid developments in recreational fisheries management, starting with the introduction of state-wide bag limits in 1991; followed by area specific controls at Ningaloo in 1992; landing limits in Exmouth Gulf in 1993; strict controls on the take of pink snapper in Shark Bay’s inner gulfs in 1997; new bag limits for Shark Bay in 1998; and the introduction of a management system for the charter and aquatic tour industry in 1999. The management proposals presented for community discussion in this paper are aimed at maintaining or improving the quality and diversity of the Gascoyne's …

Coastal Land And Groundwater For Horticulture From Gingin To Augusta, Dennis Van Gool, Werner Runge

Resource management technical reports

Due to a variety of factors, including infrastructure needs, labour requirements and transport costs, horticulture is often located near major urban centres. This study focuses on the coastal plain region from Gingin to Augusta. This region accommodates over 80% of Western Australia’s population and includes the State’s major urban centres. This region accounts for over half the State’s horticultural production with a gross value of production of $244 million (adjusted ABS values, see section 1.2). Increasing population pressures and increasing demand for horticultural produce have resulted in competition for the limited land resources in this area.

Land Evaluation Standards For Land Resource Mapping : Guidelines For Assessing Land Qualities And Determining Land Capability In South-West Western Australia, Dennis Van Gool, Geoff Allan Moore

Resource management technical reports

Updated by report 298, van Gool, D, Tille, P J, and Moore, G A. (2005)
This report provides a standard method for attributing and evaluating digital land resource maps in Western Australia so that strategic decisions about the management, development and consevation of land resources can be based on the best information available. The standards update the generic methodology described by Wells and King (1989) which have been used routinely for the assessment of land resources in catchment and land use planning in Western Australia.

Agwest Revegetation Monitoring Activity: Evaluation 1999, Caroline Hatherly

All other publications

During May 1999, an evaluation on the Agriculture Western Australia (AGWEST) Revegetation Monitoring Activity was undertaken. The evaluation was designed to track how the Land Conservation District Committees (LCDCs) in the Peel Harvey Catchment utilised the AGWEST Revegetation Monitoring Activity, and to determine if AGWEST's objectives of the project were being met It also gave the community a chance to provide feedback on their experiences with the Monitoring Activity, and suggest future changes

The survey concluded that the AGWEST Revegetation Monitoring Activity was used by LCDCs as a valuable tool for recording, monitoring and planning landcare projects. However, the process …

Social And Economic Data For Regional And Natural Resource Management In Western Australia's South West Catchment : Results Of The 2006 Landholder Survey, Department Of Agriculture And Food, Western Australia, South West Catchments Council (W.A.), Michael Hanslip, Australia. Bureau Of Rural Sciences.

All other publications

This report presents a summary of the key findings from a mailed survey to 2,000 landholders in the South West Region of Western Australia in 2006. The survey gathered information on the key social and economic factors affecting landholder decision-making about the adoption of practices expected to improve the management of natural resources in the region. The response rate for the survey was 69.4%.

The South West Catchment Council, Western Australian Department of Agriculture and Food and the Bureau of Rural Sciences were key project partners. Funding was from a mix of national, state and regional programmes, including the Natural …

Using Spatial Systems To Establish Priorities For Catchment Management, David Deeley, David Weaver, J Hick

Conference papers and presentations

Priorities for catchment management can be established based on either, an objective assessment of relative priorities throughout the catchment, or by simply responding to crises associated with particular land uses and their sectional interests. While the latter method can have advantages in terms of establishing community good will, team cohesion, and a sense of achievement for particular sectional interests, it may have shortcomings in terms of a more objective and rational assessment of the relative magnitude and hence priority of land management problems. Spatial modelling using GIS can form the basis for developing a catchment-wide understanding of the relative importance …

A Review Of The Anticoagulant Pesticide Pindone, Laurie E. Twigg, Tim J. Lowe, Gary R. Martin, Garry S. Gray

Books & book chapters

A review of the use of pindone for rabbit control in Western Australia is timely due to increased public concern over the use of this toxin, and because non-target deaths of some native Australian animals have been known to occur following its use. Pindone is one of the first generation indandione anticoagulant rodenticides which were developed in the late 1940' s. The toxicity of anticoagulants arises from their inhibition of vitamin K-dependent clotting factors in the blood. Thus therapeutic administration of vitamin K provides a reliable antidote against anticoagulant poisoning. Pindone is slow acting and works best with repeated small …

Salinity And Hydrology Of The Fence Road Catchment : A Focus Catchment Of The Blackwood Basin, Ben Whitfield

Resource management technical reports

It is the clearing of native vegetation and replacement with lower water-use annual crops and pastures that is responsible for the developing salinity problem. Traditional farming practices have led to increased recharge to the groundwater systems resulting in increased storage and/or greater areas or rates of discharge. Groundwater monitoring has revealed variable rates of rise throughout the Fence Road catchment, from static to 0.6 metres per year, in a period of average to below average rainfall.
