Degradation Of Remnant Vegetation, Richard George, Don Mcfarlane, Russell Speed Jan 1996

Degradation Of Remnant Vegetation, Richard George, Don Mcfarlane, Russell Speed

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

Remnant vegetation, wetlands and riverine systems on both private and public land throughout south-western Australia are being rapidly degraded by dryland salinity, inundation, silting, nutrient enrichment and weed invasion. Richard George, Don McFarlane and Russel Speed outline some of the reasons why this is happening and provide some case studies that highlight actions to protect these remnants.


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.


Soils Of The Ivanhoe West Bank East Kimberley Western Australia, C Grose, N Schoknecht Jan 1996

Soils Of The Ivanhoe West Bank East Kimberley Western Australia, C Grose, N Schoknecht

Resource management technical reports

A brief assessment of the soils of 2,064 ha of land on the Ivanhoe West Bank and their suitability for irrigated agriculture was conducted in May-June 1994. Sandy or loamy soils occur on broad levees adjacent to the Ord River, and areas of 'black soil' and 'red soil' plains occur behind these levees. Some areas of the red soil plain and levees are deeply dissected, and occasional active erosion is evident.
