Abstract

The inventory and condition survey of the Pilbara region, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1995 and 1999, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed covers about 181 723 km². Seven towns fall within it – Port Hedland, Onslow, Pannawonica, Wittenoom, Marble Bar, Nullagine and Newman. Pastoralism is the most extensive land use. Forty-four pastoral leases fall wholly or partly within the survey area and collectively occupy about 105 240km² (58%) of the area. Mining is an important land use, which is largely confined to ironstone ranges and greenstone belts. Twenty-one broad soil groups are identified within the survey area. The most outstanding characteristic of the soils is the predominant red colour. Stony mantles and shallowness are also a feature. The flora of the area is diverse, with 1137 vascular species recorded during the survey. Of these, 1094 were native species.
