Annean Station Management Plan, A A. Mitchell

Resource management technical reports

Annean Station's carrying capacity has been estimated at 8,340 sheep on its 168,539 hectares. The halophyte pastures of Carnegie Land System were in good condition while those of Mileura Land System were in poor condition. The wandarrie pasture of the Belele Land System was in fair to poor condition. This system comnprises 34 per cent of Annean's area and is estimated as capable of presently carrying 2,900 stock.


Pastoral Land Degradation: The Fitzroy As A Case Study, Alan L. Payne, Ronald B. Hacker Jan 1983

Pastoral Land Degradation: The Fitzroy As A Case Study, Alan L. Payne, Ronald B. Hacker

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

When large numbers of domestic livestock are superimposed on native vegetation in semi-arid and arid areas of the world, the ecological balance inevitably changes. In extreme cases these changes include such degradation as drastic losses of vegetation and active soil erosion. Areas affected in this way are unproductive for most purposes.

Western Australia's Fitzroy River valley has deteriorated in this way. Today, this once-­productive grazing country is so degraded that it has become a matter of concern to Governments, the pastoral industry and others.

This article gives a brief history of land degradation in parts of the Fitzroy River valley, …

Curbur Station : Inventory Of The Range And Its Management, Alexander Mcrae Holm Dec 1982

Curbur Station : Inventory Of The Range And Its Management, Alexander Mcrae Holm

Resource management technical reports

Ten land systems were identified, descriped and mapped. potential feed status was assessed for each land system. The land systems were then ranked accordingly and stocking rates allocated. Wongdong saline shrublands was considered to be the most productive system and Narryer hills, outcrops and breakaways the least productive. An assessment was made of the range condition and erosion status of the least. These assessments indicated that most of the pastures had been heavily utilized in the past.

Land Degradation In The Fitzroy Valley Of Western Australia, Department Of Agriculture, Western Australia. Rangeland Management Branch Aug 1981

Land Degradation In The Fitzroy Valley Of Western Australia, Department Of Agriculture, Western Australia. Rangeland Management Branch

Resource management technical reports

The report reassesses the condition of formerly valuable grazing lands of the Fitzroy River valley frontage lands. It is hoped that the submission will promote discussion on the problems of degenerated pastoral land and increase the resolve of all concerned to take the necessary action for their restoration. The frontage lands flank the major rivers of the area, the Fitzroy, the Margaret and the Meda and their tributaries. The frontage is capable of supporting the best pastures in the Kimberley, but unwise and uncontrolled stocking has profoundly degraded and eroded the most productive parts. There are about 5,800 square kilometres …


A Survey Of Land Suitable For Townsville Stylo In The North Kimberley Of W.A. 1973, A Kubicki, J. Beer Jan 1975

A Survey Of Land Suitable For Townsville Stylo In The North Kimberley Of W.A. 1973, A Kubicki, J. Beer

Books & book chapters

The aims of the survey were to -

(a) define the extent and actual location of country suitable for the production of non-indigenous pastures; in particular to classify the land for its suitability for Townsville stylo (Styioaanthes hurniiia).

(b) map the areas so defined on a land system basis.

The area surveyed covered approximately 88 000 sq.km (33 968 sq.miles) and included most of the catchments of the Carson, Drysdale, King Edward, Prince Regent, Charnley, Isdell and Chapman Rivers. It covered the country between latitude 14°S and 17°S and longitude 124°30'E and 127°30'E.


The Soil Conservation Service : Its Basis Of Co-Operation With Landowners, G W. Spencer, J. E. Watson Jan 1973

The Soil Conservation Service : Its Basis Of Co-Operation With Landowners, G W. Spencer, J. E. Watson

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

The Soil Conservation Act of 1945 set up within the Department of Agriculture a Soil Conservation Service under the control of a Commissioner of Soil Conservation.

The Service aims to promote types of land use which will conserve the soil and prevent or overcome soil erosion. It also aims to educate landholders and the public generally in the aims and practice of soil conservation.

This article relates mainly to farm land activities, and in particular the co-operation of the Service with individual primary producer landholders for the prevention and control of erosion on their land.


A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon Jan 1972

A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon

Resource management technical reports

Severe flooding in Carnarvon followed heavy rains on the Gascoyne Catchment in February 1961. The flooding and erosion were extensive enough to suggest that run-off from the catchment was excessive. Lightfoot (1961)* reported that excess run-off was due to degradation of the catchment area. This report will describe the catchment area in terms of the degradation of its rangeland and its susceptibility to erosion.

Firebreaks Without Erosion : Hints To Prevent Firebreak Erosion, Department Of Agriculture, Western Australia

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

AGRICULTURAL fire risks are now greater than they have been in the past and are steadily increasing with the advance of agriculture in Western Australia.

During the past 20 years the area of cleared arable land and the area under crop have more than doubled.

The area of established pasture is four times as great as it was. Pastures and crops are much more productive —and more liable to carry destructive fires than they were.

Rabbit Control In 1960, C Marshall Jan 1960

Rabbit Control In 1960, C Marshall

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

IN the year 1859, an enthusiastic sportsman in Victoria took delivery from the clipper "Lightning" of a small consignment of wild European rabbits which he joyfully released on his estate at Barwon Park, near Geelong, in order to assure himself of some rough shooting.

He was not the only rabbit importer on record—tame rabbits were brought into Australia before and after 1895 and doubtless there were other importations of the wild rabbit—but he is generally credited—or discredited—with having triggered off the rabbit plague.
