Abstract

The inventory and condition survey of rangelands in the Carnarvon Basin, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1980 and 1982, 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 74 500km² in the Carnarvon Basin and Shark Bay regions, and includes the catchments of the Lyndon and Minilya rivers and the lower reaches of the Gascoyne and Wooramel Rivers. The vegetation of the Carnarvon Basin area is mainly dominated by perennial shrubs. A small number of botanical families contain a large proportion of the dominant perennials in the area. Of these Acacia, Eremophila and Cassia are pre-eminent in the taller shrub communities, Atriplex and Maireana in the low chenopod shrublands, Eucalyptus in the low woodlands and Triodia and Plectrachne in the hummock grasslands.
