An Assessment Of The Impact Of Ophthalmia Dam On The Floodplains Of The Fortescue River On Ethel Creek And Roy Hill Stations, A L. Payne, A A. Mitchell
An Assessment Of The Impact Of Ophthalmia Dam On The Floodplains Of The Fortescue River On Ethel Creek And Roy Hill Stations, A L. Payne, A A. Mitchell
Resource management technical reports
The area surveyed covered all of the floodplains of the Fortescue River, and Jigalong, Jimblebar and Carramulla Creeks which fall within Ethel Creek and Roy Hill stations. Two serious, distinct and largely unrelated environmental problems are evident on the area surveyed. The first problem is longstanding, severe landscape degradation in the form of almost complete loss of perennial vegetative cover and soil erosion (mainly scalding) due to historical overgrazing.

Tree Crops For Profit And Land Improvement, John Bartle
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australian agriculture is deficient in good perennial species. The traditional segregation of agriculture and forestry has diverted attention from commercial wood producing trees as a potential perennial crop. Recently, scientists have made rapid progress in developing tree cropping systems suitable for extensive use in the wetter (more than 600 mm average annual rainfall) areas of the lower south-west. There is potential for a major industry based on fast-growing eucalypts for pulpwood. The foundations for this industry developed from work on agroforestry, forestry sharefarming and salinity control.

Reclaiming Sandplain Seeps Planting Trees, Richard George
Journal of the Department of Agriculture, Western Australia, Series 4
Sandplain seeps affect large areas of agricultural land in Western Australia's eastern and northern wheatbelt and in the Great Southern. These seeps are estimated to account for about 10 per cent of dryland salinity in the agricultural area. Research and field observations show that seeps may be cheaply and quickly reclaimed using various types of drains or small blocks of trees (George 1990). This article discusses results of reclamation methods associated with tree planting on sandplain seeps in the eastern wheatbelt.
