Annean Station Management Plan, A A. Mitchell
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.
Hydrological Studies In Soil Salinity, C J. Henschke
Hydrological Studies In Soil Salinity, C J. Henschke
Resource management technical reports
Investigations involved examination of near-surface indurated layers to investigate their role in saltland formation. It was found that groundwater could move readily through this layer due to the presence of macro-pores. Close examination of apparently impermeable pallid zone clays, shows that decayed tree roots and large diameter voids provide a continuous pathway for the veritical transport of saline water from deeper aquifers.
Agricultural Water Quality Criteria : Irrigation Aspects., P R. George
Agricultural Water Quality Criteria : Irrigation Aspects., P R. George
Resource management technical reports
Water quality criteria for irrigation are imprecise. The final result of quality evaluation depends on plant, soil and climatic variables all of which can be inter-dependent. A range of management strategies of varying complexity are available to mitigate the effects of poor quality water. The heavy winter rainfall in the south-west of Western Australia affects the applicability of published salinity criteria most of which have been developed in arid and semi-arid environments with little effective rainfall.

Quobba Point Chalet Development Land Capability Study [And] Environmental Consideration, J R H Riches, L E. Chalmers
Quobba Point Chalet Development Land Capability Study [And] Environmental Consideration, J R H Riches, L E. Chalmers
Resource management technical reports
The preferred area for development is the Old Stabilised Dune System. The Hind Dune Flat is a stable area but is limited in size. Other environmental and town planning considerations may militate against development of this area for Chalet Development.
Progress Report On Effects Of Contour Banking On Surface Runoff At The Berkshire Valley Experimental Catchment (Near Moora) 1961-82, K J. Bligh
Resource management technical reports
The time lag prior to peak runoff following rains of comparable high intensity increased by approximately 80 per cent in the largest event after the construction of contour banks. Although 80 per cent more runoff also occurred because the catchment was wetter and had been cultivated for three years in a row, the peak rate of runoff increased by only approximately 20 per cent. That the peak rate was not increased by 80 per cent, may be primarily attirbuted to the effect of the contour banks.

Curbur Station : Inventory Of The Range And Its Management, Alexander Mcrae Holm
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
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 …
Wind Erosion In The Jerramungup Area 1980-1981, Bryan J. Goddard, M G. Humphry, D J. Carter
Wind Erosion In The Jerramungup Area 1980-1981, Bryan J. Goddard, M G. Humphry, D J. Carter
Resource management technical reports
An investigation of the wind erosion problem at Jerramungup was conducted by on-farm survey and Landsat interpretation from September to November 1981. Sandblasting and wind erosion were estimated to have seriousloy affected some 44,000 ha in 1980 and over 64,000 ha in 1981. The 1981 damage estimate is conservative, because a much greater area of pasture land was affected by erosion in May-July but achieved vegetative cover by later winter.
A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon
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.
