Fortescue River (WA), Eucalyptus, Western Australia, Erosion, Mortality, Dams, Environmental factors, Soil degradation, Ophthalmia Dam (WA), Roy Hill Station (WA), Ethel Creek Station (WA), Environmental impact
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.
