Summary When flooded, Lake Eyre supports major breeding events of the congregatory Banded Stilt and Australian Pelican, and more than 1% of the global populations of the congregatory Silver Gull, Red-necked Avocet, Sharp-tailed Sandpiper, Red-necked Stint and Caspian Tern.
Site description The IBA is identical to Lake Eyre, which is located in central South Australia. The boundary of the IBA excludes dryland areas of Lake Eyre National Park and Elliott Price Conservation Park. Lake Eyre is both the largest saltlake and, at 15 m below sea level, the lowest point in Australia. It is a terminal catchment for various river systems in the arid region of central Australia, which are usually dry but occasionally flood. Lake Eyre floods from strong rainfall in the Queensland catchments (usually in La Niña years), or from local rain. It is flooded on average about once every eight years, but has been filled to capacity on only three occasions in the past 150 years. When flooding begins, the waters of Lake Eyre are almost fresh and can support freshwater fish carried to the lake by associated rivers. The salinity of the waters then increases as the salt crust dissolves, and brine shrimps hatch and breed unless depredated by fish from inflowing rivers. When over 4 m deep the lake is less salty than the sea but the salinity increases as the water evaporates. Many of the colonial birds nest on low, sparsely vegetated islands in the lake.
