Pastoral Lease Assessment Using Geospatial Analysis, T P. Robinson, P E. Novelly, R Corner, Philip Thomas, A Russell-Browm Aug 2012

Pastoral Lease Assessment Using Geospatial Analysis, T P. Robinson, P E. Novelly, R Corner, Philip Thomas, A Russell-Browm

Resource management technical reports

Seven remote sensing based Vegetation Indices (NDSVI, STVI-3, NDVI, Green + Red, Red, Land Monitor and STVI-1) were tested for their potential to discriminate between “poor” and “good” range condition assessments in Western Australia’s pastoral rangelands. Indices were computed using the Australian Greenhouse Office National Carbon Accounting System (AGO NCAS) repository of calibrated Landsat TM/ETM+ mosaics. Discrimination potential was assessed at two levels of stratification – station level (identical to the stratification used to collect the traverse data), and functional group level (an aggregation of similar land systems);


A Report On The Gascoyne River Catchment Following The 2010/11 Flood Events, P A. Waddell, P W.E Thomas, Paul A. Findlater May 2012

A Report On The Gascoyne River Catchment Following The 2010/11 Flood Events, P A. Waddell, P W.E Thomas, Paul A. Findlater

Resource management technical reports

In December 2010 an extreme tropical storm resulted in widespread flooding at Carnarvon and across the catchment. Another two flood events followed during the summer of 2010–11

The rationale for this assessment is to provide illustrative evidence on the role that perennial vegetation groundcover management has in influencing the risk of flooding and soil loss in the catchment. It may be possible that the impact of flooding associated with extreme storm events can be reduced. This report focuses on catchment condition and is not a review of the pastoral industry’s economic viability.

Extent And Impacts Of Dryland Salinity, C E. Mcconnell, R Short Jan 2001

Extent And Impacts Of Dryland Salinity, C E. Mcconnell, R Short

Resource management technical reports

The extent and impact of dryland salinity in Western Australia was based on analysis of groundwater depth and trend and the risk of shallow watertables is derived from these two attributes. As dryland salinity is caused by shallow watertables, the risk of salinity is inferred from the risk of shallow watertables.

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 normally located near major urban centres. This study focuses on the coastal plain region from Gingin to Augusta. This region accomodates over 80% of Western Australia's population and includes the States major urban centres. This region also accounts for over half the State's horticultural production with a gross value of production of $244 million.


Native Vegetation On Farms Survey 1996 : A Survey Of Farmers Attitudes To Native Vegetation And Landcare In The Wheatbelt Of Western Australia, Suzanne Jenkins May 1997

Native Vegetation On Farms Survey 1996 : A Survey Of Farmers Attitudes To Native Vegetation And Landcare In The Wheatbelt Of Western Australia, Suzanne Jenkins

Resource management technical reports

The Native Vegetation on Farms survey 1996 was performed to assess the attitudes of farmers to a number of issues related to existing native vegetation on farmland, the replanting of vegetation on farms and land degradation. Research has shown that it is important for a proportion of all farmland to have some native vegetation for ecological stability, to regulate hydrological processes and for long-term sustainability of farm production.

Soils Of The Weaber Plain, East Kimberley, Western Australia, J C. Dixon Jan 1996

Soils Of The Weaber Plain, East Kimberley, Western Australia, J C. Dixon

Resource management technical reports

The Weaber Plain, north-east of Kununurra, is one of three "black soil" plains in the Kimberley area of Western Australia. It comprises about 15,000 hectares of irrigable land, part of which is known as Stage 2 of the Ord River Irrigation Area (ORIA). The area was surveyed in 1977 following a similar survey of the nearby Keep River Plain and preceding a survey of the Ivanhoe Plain, which has since been developed commercially. Map units and soil series used in those reports have also been used for this rep ility in crop selection, preferring high water use crops.


Soils Of The Knox Creek Plain East Kimberley Western Australia And Northern Territory, C Grose, Noel Schoknecht Jan 1996

Soils Of The Knox Creek Plain East Kimberley Western Australia And Northern Territory, C Grose, Noel Schoknecht

Resource management technical reports

An assessment of the soils and landforms of approximately 12,000 ha in the Knox Creek Plain in Western Australia and the Northern Territory was conducted in May and June 1994. Seventeen map units were identified and their soils, landform and vegetation characteristics were described. Grey or brown cracking clays predominate on the plain, however variable red or brown soils on the coarser alluvium of remnant levees are common in the south and south-east.

Floristic Survey Of Remnant Vegetation In The Dandaragan Area, Western Australia, Edward Arnold Griffin Jan 1990

Floristic Survey Of Remnant Vegetation In The Dandaragan Area, Western Australia, Edward Arnold Griffin

Resource management technical reports

A study involving the documentation of the extent and floristic composition of patches of native vegetation left uncleared by agricultural development is described. Floristic regions were defined in the study area by detailed analysis of the floristic data. The concentration of the major conservation reserves in only a few of these regions left the floristic variation of most of these regions poorly represented conservation reserves. About 13 percent of the private property remains uncleared.

Management Of Native Vegetation On Farmland In The Wheatbelt Of Western Australia, A M. Coates Oct 1987

Management Of Native Vegetation On Farmland In The Wheatbelt Of Western Australia, A M. Coates

Resource management technical reports

Clearing in the wheatbelt region of Western Australia has been rapid and extensive. The mapping of remnant vegetation in the shires of Dumbleyung, Lake Grace, Pingelly and Tammin with the use of the most recent aerial photography (1984) demonstrates the extent of clearing especially in the old established farming areas. Only 7 per cent of the Tammin shire had been retained under native vegetation, 10 per cent of the Dumbleyung shire and 14 per cent of the Pingelly shire. In the Lake Grace shire where large areas have only recently been developed for agriculture, approximately 31 per cent had been …
