Eyre Peninsula NRM Region
This region covers an area of 80,000 square kilometres (8,000,000 hectares) in the western part of South Australia and has a population of around 55,000. The region, bounded by the Gawler Ranges in the north and the edge of the Nullarbor Plain to the west encompasses the entire Eyre Peninsula to the south as well as the surrounding coastal and marine environments, plus offshore islands. Eyre Peninsula is a diverse region with extensive coastline, natural vegetation and unique land and water systems in an arid?semi-arid zone. Annual rainfall ranges from 250-600mm with average temperatures from 8-23oC in summer and 11-15 oC in winter. Ancient metamorphic rocks form the basement of the peninsula. The soils of the region generally are nutrient poor due to their high degree of weathering, or to their sandy or calcareous nature, and are prone to erosion. However, when managed appropriately these soils provide significant economic returns. Winter cropping of wheat, barley, oilseed and pulses, plus wool and livestock production, are the main farm enterprises.
