Pastoral Resources And Their Management In The North-Eastern Goldfields, Western Australia, H J. Pringle Sep 1994

Pastoral Resources And Their Management In The North-Eastern Goldfields, Western Australia, H J. Pringle

Agriculture reports

This report commences with a brief section in which rangeland survey information is put into a pastoral management context. It then describes the environment in terms of types of rangeland and climate. Types of rangeland are described in terms of pasture types, land systems and land types. A pasture type is a kind of land at a plant community or landform scale. It is what is seen out of the window of a vehicle and what monitoring sites are located on. A land system can be seen as a pattern of pasture types in a characteristic position in the landscape. …


Bulletin 4279 - Streamlining - An Environmentally Sustainable Drainage Network For The Swan Coastal Plain (Peel-Harvey Catchment), Garry Heady, Neil Guise Aug 1994

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.


Native Vegetation Handbook For The Shire Of Narrogin, Shaun B. Grein May 1994

Native Vegetation Handbook For The Shire Of Narrogin, Shaun B. Grein

Native vegetation handbook series

The management of native vegetation and agricultural land is closely related. It is vital that both native vegetation and agricultural land issues are considered within the context of their ecological area of influence. Both have a wide range of effects on each other and as a consequence should be managed together. For example native vegetation impacts on the hydrology of agricultural land. Conversely nutrients can be transferred from agricultural land to remnants of native vegetation. This booklet is one of a series covering the agricultural region of Western Australia and provides agricultural land managers with information relating to the natural …

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 …


Miscellaneous Publication 10/94 - The Climate And Soils Of South-Western Australia In Relation To Vine Growing, J. S. Gladstones Mar 1994

Miscellaneous Publication 10/94 - The Climate And Soils Of South-Western Australia In Relation To Vine Growing, J. S. Gladstones

Viticulture research reports

The vine industry in Western Australia is at present located mainly in the Swan Valley, some 15 miles inland from Perth. It produces currants for export, wine grapes, and table grapes for both local and export markets, in approximately that order of importance.

Climatically, the Swan Valley is well suited to vine fruit production. With an annual rainfall of about 34 inches, it has a mild, wet, almost frost-free winter, and a warm, dry summer. Olmo (1956) concluded that the Swan was especially well suited to the production of currants, table grapes and sweet dessert wines. However, he considered that …

How Sustainable Is Grazing Sheep On Annual Pastures In The Woolbelt?, Don Mcfarlane, Richard George Jan 1994

How Sustainable Is Grazing Sheep On Annual Pastures In The Woolbelt?, Don Mcfarlane, Richard George

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

Low wool prices have reduced the profitability of producing wool from clover-based annual pastures in the south-western woo/belt. The heavy reliance on one commodity is economically unsustainable for many farmers. But we should also consider how ecologically sustainable the practice is.

Shallow-rooted annual pastures contribute to widespread salinity in the area, annual legumes are acidifying the soils and making them water repellent, and bare, detached soils from heavy grazing cause sheet and rill erosion during autumn storms. In addition, stock are degrading remnant vegetation and destroying the soil's structure.

To counteract this degradation, the woo/belt needs more perennial pastures and …


Miscellaneous Publication 42/93 - Development And Dissemination Of Design Methods For Rangeland Paddocks Which Maximise Animal Production And Minimise Land Degradation, Shane Cridland, Mark Stafford Smith Dec 1993

Miscellaneous Publication 42/93 - Development And Dissemination Of Design Methods For Rangeland Paddocks Which Maximise Animal Production And Minimise Land Degradation, Shane Cridland, Mark Stafford Smith

Animal production and livestock published reports

Surveys of rangeland resources in Western Australia to date have shown that 23% of the area surveyed is in poor range condition. Poor condition is characterised by the loss of perennial vegetation allowing wind and water erosion. Approximately another 37% is in only fair range condition (Curry and Hacker 1990).

The loss of range condition is partly due to uneven use of paddocks by sheep and cattle. The areas close to water and the preferred pasture types are often over-utilised, while areas well away from water and less preferred pasture types are under-utilised. The result is that rangeland in good, …


Resource Inventory And Condition Survey Of The Ord River Regeneration Reserve, John De Salis Dec 1993

Resource Inventory And Condition Survey Of The Ord River Regeneration Reserve, John De Salis

Natural resources published reports

It is now some 33 years since the Ord River Regeneration Project, the largest and most ambitious of its kind in Australian rangelands, commenced.

During this time there have been a number of publications and miscellaneous reports about the project, but this publication is by far the most comprehensive produced to date. Although the field work was undertaken in 1981, the findings recorded here will stand in a good stead as a detailed account and reference work for years to come.

Much has changed within the Regeneration Reserve area since the project commenced. Cattle and feral donkey numbers have finally …


Napier-King Land Conservation District : Land Management Manual, Peter Hocking Jun 1993

Napier-King Land Conservation District : Land Management Manual, Peter Hocking

All other publications

With the discovery of the role of trace elements, large tracts of land in the south west of Western Australia, previously regarded as unsuitable for agriculture, were cleared in the 1950s and 1960s. Much of this land was taken up as Conditional Purchase Blocks, a scheme which enabled conversion of unalienated crown land to freehold title providing a set proportion of the block was 'developed'.

However, the removal of the natural deep rooted vegetation and its replacement with pasture species (up to 90% of privately owned land in the Napier-King LCD area is cleared) has not been without problems. The …


Installing Photographic Rangeland Monitoring Sites In Grassland Environments, Andrew Mclaughlin Apr 1993

Installing Photographic Rangeland Monitoring Sites In Grassland Environments, Andrew Mclaughlin

Agriculture reports

Photographic monitoring offers pastoralists an inexpensive management tool that can help to better understand how varying management practices affect the rangeland. Using a monitoring system also helps take the guesswork out of knowing what changes to vegetation and soils have occurred over time.

Saving The Catchments Of Albany's Harbours, Ashley Prout Jan 1993

Saving The Catchments Of Albany's Harbours, Ashley Prout

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

Fertiliser, particularly phosphorus, running off farm land is a major source of nutrient entering Albany's harbours. Oyster Harbour, which has a large rural catchment, is especially at risk.

The build-up in nutrients in the harbours has caused nuisance algal growth since the early 1970s and subseuent death of more than half the seagrass beds, which are vital to the areas marine life.

The Department of Agriculture, at the request of the Environmental protection Authority, has developed and promoted catchment management plans that enable rural land holders to reduce the amount of run-off into the harbours without necessarily sacrificing farm productivity. …


Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George Jan 1993

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George

Bulletins 4000 -

Careful planning can mean the difference between the success or failure of a tree planting program . Healthy , well-e stablished trees stand a better chance of survival, grow faster and are more resistant to insect attack. The need for time-consuming watering in summer is also eliminated.

The high rainfall coastal plain extends from Perth to Busselton and inland to the Darling Scarp. It receives about 800 to 1000 mm annual rainfall.

Site preparation is ideally started in summer. For a winter planting, decide before March where to plant, which varieties and how many trees to plant. Early planning allows …

Post-Shearing Losses Of Sheep Following Cyclonic Rains, M. Holm Glass, R. Jacob May 1992

Post-Shearing Losses Of Sheep Following Cyclonic Rains, M. Holm Glass, R. Jacob

Animal production and livestock published reports

Sudden unpredicted rainfall during summer has caused high mortality rates in newly shorn sheep on at least two previous occasions. These occurred at Darkan, Western Australia, in 1982 (Buckman 1982) and at Kybylolite in the south-east of South Australia in 1960 (Geytenbeek 1982).

Geytenbeek (1982) reported an average mortality of 8.3%, which was highest for sheep within five days of shearing. The mortality declined for animals shorn more than seven days before the rain.

Buckman (1982) reported an average mortality of 27.9% which was highest within 12 days of shearing. The losses related directly to the amount of rain received. …

Effects Of Waterlogging On Crop And Pasture Production In The Upper Great Southern, Western Australia, J F. Wallace, G A. Wheaton, D J. Mcfarlane Mar 1992

Effects Of Waterlogging On Crop And Pasture Production In The Upper Great Southern, Western Australia, J F. Wallace, G A. Wheaton, D J. Mcfarlane

Technical Bulletins

Separate estimates of the effect of waterlogging on cereal yields were made using rainfall and crop yield statistics, and remote sensing. Both methods showed that waterlogging costs tens of millions of dollars each year in lost crop production in the Upper Great Southern Statistical Division. The costs will be over $100 m in wet years. Losses in pasture production are likely to be of a similar magnitude, but are harder to quantify.


Red Kangaroos Can Set Back Range Regeneration, Andrew Mclaughlin Jan 1992

Red Kangaroos Can Set Back Range Regeneration, Andrew Mclaughlin

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

After years of severe drought, stocking rates in Western Australia s arid rangelands have been kept low since the 1970s to allow native pastures to regenerate. As well, extensive re-seeding programs have started and sheep and cattle grazing on these areas has been restricted or eliminated. However, pasture regeneration in the rangelands can only succeed when grazing by all animals - sheep, cattle, kangaroos, goo.ts, camels, brumbies and donkeys - is controlled Many more red kangaroos roam throughout Western Australia's pastoral areas today than 20 years ago. The installation of windmills and troughs to water domestic livestock has allowed kangaroo …
