SOILS

Western Australia’s rangelands are home to some of the oldest known best-preserved pieces of crust on Earth, initially forming over 3.53 billion years ago. Due to the extreme length of time some areas of Western Australia’s geology have been exposed to the extremes of changing climates over the millions of years – our soil structures have become very weathered. As a result of poorly structured soil deposits the native plants and animals have become highly adapted to suit regions low in nutrients with erratic rainfall, producing some very unique known communities of plants and animals.

Western Australia’s soils are protected under the Soil and Land Conservation Act (1945). This Act is administered by the Soils Commissioner and the main functions of this role includes the mitigation and prevention of land degradation, promotion of soil conservation and education of land holders and the public generally about sound land management
