Salinity Risk Mapping For Assessing Carbon Farming Initiative Proposals: Decision Support And Data Requirements, Paul Raper, Peter Gardiner
Resource management technical reports
The Clean Energy Legislation passed by the Australian Parliament on 8 November 2011 links the carbon price to the Carbon Farming Initiative (CFI). Under the Carbon Credits (Carbon Farming Initiative) Act 2011 (the Act), proponents need to consider regional natural resource management (NRM) plans to ensure that tree plantings for carbon bio-sequestration maximise environmental benefits and avoid unintended adverse effects on biodiversity, water and agricultural production systems.

Fire Management Guidelines For Southern Shrubland And Pilbara Pastoral Rangelands : Best Management Practice Guidelines, Department Of Agriculture And Food, Western Australia
Fire Management Guidelines For Southern Shrubland And Pilbara Pastoral Rangelands : Best Management Practice Guidelines, Department Of Agriculture And Food, Western Australia
Land resources best practice series
Fire is integral to many ecosystems in Western Australian rangelands. Controlled fire can reduce the risk of wild fire, benefit pasture productivity and contribute positively to biodiversity values. Uncontrolled fire is a threat to safety and the business viability of pastoral enterprises and threatens rangeland biodiversity and productivity.This document deals with property-scale management of pastoral leases. Many fire regime issues are more regional in character. These include community safety and health, the impact on regional economies, the societal and cultural values of landscape and the effects on tourism. Ecologically the high productivity, diversity and palatability of recently burnt vegetation is …
Fire Management Guidelines For Kimberley Pastoral Rangelands : Best Management Practice Guidelines, Department Of Agriculture And Food, Western Australia
Fire Management Guidelines For Kimberley Pastoral Rangelands : Best Management Practice Guidelines, Department Of Agriculture And Food, Western Australia
Land resources best practice series
Kimberley pastoralists operate in a highly fire-prone environment. Uncontrolled fires pose significant economic, safety, and environmental risks to pastoral enterprises. In contrast, the controlled use of fire can benefit land management, animal production and biodiversity conservation. For any given country type, the interactions of fire, grazing and weather have complex effects on both land condition and animal production. Although general guidelines on the use of fire are valuable, based as they are on a combination of experience and available research findings, they should best be regarded as providing a starting point. At the property level, an adaptive approach that incorporates …
Trees Working In Western Australia, Dave Berry
Trees Working In Western Australia, Dave Berry
Journal of the Department of Agriculture, Western Australia, Series 4
There is an air of inevirability about farm forestry - no-one disputs that planting trees is a sure route to curbing agriculture's serious land degredation problem. Dave Berry talks with some of the key players developing the industry.

Rex ' 96 : An Expert Guide To Revegetation, David Bicknell
Journal of the Department of Agriculture, Western Australia, Series 4
Agriculture Western Australia has provided coordination and technical input to a powerful source of information on plants for Australian conditions. David Bicknell outlines some of its features and uses.
Farmers, local government, advisers and even gardeners often have trouble finding the right plant for the right place for a given purpose. Rather than spend a lot of time, money and effort looking through scattered sources of information, many people stick with a limited number of species year after year. This neglects plants that may be much better suited to the purpose, and also fails to develop Australia's huge range of …
Merging Conservation With Production In Remnant Bush, Anne Morgan, Alison Fuss
Merging Conservation With Production In Remnant Bush, Anne Morgan, Alison Fuss
Journal of the Department of Agriculture, Western Australia, Series 4
Exports of cutflowers and foliage from Western Australia are now worth about $17 million a year. A third of this is picked from the bush, either on Crown Land or areas of remnant bush on private property. While the industry's future lies in cultivation, bush picking is likely to remain important for some years. This can provide both extra income for farmers and benefit the environment - as long as care is taken
Bluegum Timberbelts For Profitable Landcare, Peter Eckersley
Bluegum Timberbelts For Profitable Landcare, Peter Eckersley
Journal of the Department of Agriculture, Western Australia, Series 4
Revegetation with tasmanian bluegums in wide-spaced timberbelts appears to offer high returns, especially in areas where high winds cause crop and stock losses and where land can be saved from salinity and wwaterlogging.
In the South Coast and South-WestRegions, timberbelts will complement existing enterprises and so optimise overall land use. Graziers should be able to maintaine their stock numbers while creating an on-farm superannuation package.
The Department of Conservation and Land Management has been a major player in the development of bluegum timberbelts, but a few farmers are now adapting this concept to better suit their needs. Initial results are …
Managing Bushland On The Farm, Penny Hussey
Managing Bushland On The Farm, Penny Hussey
Journal of the Department of Agriculture, Western Australia, Series 4
Since the time of European settlement in Western Australia, the replacement of native vegetation with crops and pastures has led to problems for both agricultural production and nature conservation. The most obvious of these are hydrological changes leading to salinisation and waterlogging, and the extinction of some native plants and animals.
Protection of remaining remnants of native bushland, together with revegetation, is increasingly seen as important ways of achieving sustainable agriculture and maintaining our unique wildlife.
Honey Production In Western Australia, Rob Manning
Honey Production In Western Australia, Rob Manning
Journal of the Department of Agriculture, Western Australia, Series 4
the first ever survey of the potential production and value of apiary products from the south-west of Western Australia has shown beekeepers are collecting only 10 per cent of the potential honey crop.
The biggeest losses in honey production are caused by the enviroment, such as protracted drought, and extreme temperatures, heavy rain and cyclones during flowering. Fire, apiary sites leased but not used, and logging of forests also reduce the availability of apiary sites for honey production.

Tree Crops For Profit And Land Improvement, John Bartle
Tree Crops For Profit And Land Improvement, John Bartle
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australian agriculture is deficient in good perennial species. The traditional segregation of agriculture and forestry has diverted attention from commercial wood producing trees as a potential perennial crop. Recently, scientists have made rapid progress in developing tree cropping systems suitable for extensive use in the wetter (more than 600 mm average annual rainfall) areas of the lower south-west. There is potential for a major industry based on fast-growing eucalypts for pulpwood. The foundations for this industry developed from work on agroforestry, forestry sharefarming and salinity control.
Wildlife Corridors In The Wheatbelt, Richard Hobbs, Denis Saunders
Wildlife Corridors In The Wheatbelt, Richard Hobbs, Denis Saunders
Journal of the Department of Agriculture, Western Australia, Series 4
Native vegetation in the Western Australian wheatbelt now persists mostly in small areas that remained uncleared for various reasons. (See 'Remnant vegetation on farms is a valuable resource' on page 43.) On their own, most of these remnant areas are difficult to manage, and too small to retain viable populations of many of the birds and other animals found in the wheatbelt. These patches of vegetation can be linked by wildlife corridors, which may increase the ability of the wildlife to move about and persist in the area

Revegetating Salt-Affected Land With Shrubs, Ed Barrett-Lennard, Fionnuala Frost, Steve Vlahos, Norm Richards
Journal of the Department of Agriculture, Western Australia, Series 4
The establishment of salt-tolerant shrubs such as saltbush and bluebush on salt-affected land reduces the risk of soil erosion, and can also fit into farm programmes as a profitable enterprise. Salt-tolerant shrubs can be used as forage for sheep in summer and autumn, when the availability of annual pastures is low or annual pastures are just beginning to emerge. This article describes three methods for establishing shrubs on salt-affected land and what affects shrub establishment.
Planting Trees To Control Salinity, Nick Schofield, Phil Scott
Planting Trees To Control Salinity, Nick Schofield, Phil Scott
Journal of the Department of Agriculture, Western Australia, Series 4
Dense tree plantings covering at least 30 per cent of cleared land can lower groundwater levels by two metres or more in 10 years from the time of planting. This sizeable drop can be expected at sites receiving 700 to 800 mm of rain a year. Research by the Water Authority of Western Australia shows the most promising strategy when using trees is to put dense plantings on the discharge zone and on lower to midslopes. This strategy is successful where groundwaters contain less than 30,000 milligrams per litre total soluble salts (TSS).
This article discusses research in the 450 …

The Greening Of Australia, Martine Scheltema
Journal of the Department of Agriculture, Western Australia, Series 4
Many urban Australians have little understanding of the problems of land degradation because it's an extremely slow process that doesn 't directly influence their day-to-day lives. Understandably, they would have trouble relating to sub-soil compaction, waterlogging, increased soil acidity and salinity. They also have trouble comprehending why fencing according to soil type is an important management tool for farmers, or what role contour banks, drainage systems, the addition of gypsum and planting trees have in reversing land degradation. But given that tree loss "has been at the core of almost every aspect of land degradation in Australia ", and that …
Reclaiming Sandplain Seeps Planting Trees, Richard George
Reclaiming Sandplain Seeps Planting Trees, Richard George
Journal of the Department of Agriculture, Western Australia, Series 4
Sandplain seeps affect large areas of agricultural land in Western Australia's eastern and northern wheatbelt and in the Great Southern. These seeps are estimated to account for about 10 per cent of dryland salinity in the agricultural area. Research and field observations show that seeps may be cheaply and quickly reclaimed using various types of drains or small blocks of trees (George 1990). This article discusses results of reclamation methods associated with tree planting on sandplain seeps in the eastern wheatbelt.

Survey Of The Damage Caused To Trees By Goats, Steve Gherardi, Dick Mills, Tim Johnson
Journal of the Department of Agriculture, Western Australia, Series 4
The damage that goats can cause to trees is one of the major problems associated with their farming in the agricultural areas of Australia. It is also considered one of the main hindrances to the development of the goat industry. The Department of Agriculture s Goat Industry Development Unit surveyed mohair and cashmere producers to determine the prevalence of tree damage and its extent and severity; why producers believed goats damaged trees; and how producers minimised or prevented this damage.

Using Trees To Reclaim Land Lost To Saline Seeps, Department Of Agriculture And Food, Western Australia, Arthur Wright
Journal of the Department of Agriculture, Western Australia, Series 4
The National Soil Conservation Program (NSCP) has tapped the vigorous community support for landcare initiatives through its demonstration sites for reclaiming sandplain seeps in the Western Australian wheatbelt. The demonstrations, which use tree plantations to reclaim seeps, began in 1989. The sites are being keenly monitored by participating farmers and members of land conservation districts (LCDs).
Trees And Livestock : A Productive Co-Existence, Richard Moore
Trees And Livestock : A Productive Co-Existence, Richard Moore
Journal of the Department of Agriculture, Western Australia, Series 4
Trees, as part of farming can help to combat land degradation problems and produce a good economic return from timber at the same time. For example, there is now clear evidence that planting trees can help combat salinity by lowering water-table levels. Trees can also substantially improve overall farm productivity by providing shelter for pastures and livestock. The challenge is to find practical and economical methods of integrating trees and farming. A combination of widely-spaced trees and livestock is one promising method. This article describes the benefits of this type of agroforestry to farmers, suitable locations and how to practice …
Variable Quality Of Saltbush Seed Influences Establishment, Stephen Vlahos, Donald Nicholas, Clive Malcolm
Variable Quality Of Saltbush Seed Influences Establishment, Stephen Vlahos, Donald Nicholas, Clive Malcolm
Journal of the Department of Agriculture, Western Australia, Series 4
Farmers are using niche seeders to direct-seed saltbushes (Atriplex spp.) cheaply on large areas of salt affected land. While many factors influence successful establishment of these shrubs, fanners can control the quality of the seed they use. Too often, the lack of knowledge of saltbush seed quality has resulted in extremely poor establishment. The importance of seed quality is well recognized in the establishment of grain crops and pastures, but it is often overlooked when farmers buy or select seed of saltbush. If farmers know the quality of the seed they buy, they can make appropriate adjustments to the sowing …
Remnant Vegetation On Farms Is A Valuable Resource, Richard Hobbs, Ken Wallace
Remnant Vegetation On Farms Is A Valuable Resource, Richard Hobbs, Ken Wallace
Journal of the Department of Agriculture, Western Australia, Series 4
Retention of native vegetation on farms is important both from an ecological and an economic point of view. Productivity in the paddocks ultimately will depend on the retention and replacement of trees and shrubs in the landscape. Remnants of native vegetation can play their part by helping to ensure the long-term viability of the agricultural system, as well as greatly enhancing the quality of life for those living on the land.

Alternative Land Uses, D A. Morrison, B. C. Mattinson
Journal of the Department of Agriculture, Western Australia, Series 4
One aproach to minimise the high nutrient content and associated algal pollution of the Peel-Harvey estuarine system is to reduce phosphorus losses at their source. Farmers can do this by changing land use is such a way thar phosphorus run-off fromthe catchment soils into drainage is prevented or at least reduced.
The department of Agriculture is investigating the economics of alternative uses, particularly substituting forestry with Pinus pinaster or Eucalyptus globulus (Tasmanian blue gum) for present beef and sheep enterprises. P. pinaster is used for logging and E. globulus for pulping.

Wild Life In A Modern Age, Clee Francis Howard Jenkins
Journal of the Department of Agriculture, Western Australia, Series 4
THE present human population of the earth is estimated at about 2 1/2 thousand million, and reliable sources consider that this figure will be doubled by the year 2000.
Although the pessimistic forecasts of Malthus have not yet come true, it is obvious that the world's food requirements, must lead to increased exploitation of land and other primary resources, with consequent repercussions on all forms of wild life.
