The park is an important area for Cape Barren Geese

Lake Newland Conservation Park protects a 20 km long hypersaline lake and associated wetland complex lying on the west coast of the Eyre Peninsula of South Australia. It is separated from the sea by sand-dunes. The southern end of the reserve is about 10 km north of the small town of Elliston, and the northern end about 20 km south of Venus Bay. The park was proclaimed in 1991; some additional areas were added in 1996.[1]

Description[edit]

The park has a relatively recent geological history, with Holocene sand-dunes creating a barrier between the Southern Ocean and a depression in the Bridgewater Formation of Pleistocene limestone that is common throughout the western Eyre Peninsula. The dunes continue to encroach on the lake, lagoons and other wetlands in the park which are also fed by freshwater springs in the limestone. Average annual rainfall (recorded at Elliston) is 427 mm.[1]

Vegetation[edit]

The park contains mobile sand dunes and sub-coastal wetlands. The vegetation includes areas of previously cleared land with patches of regenerating Drooping Sheoak woodland and scattered native shrubs. The lake margins are dominated by salt-tolerant Sarcocornia and Tecticornia species. The coastal shrublands that cover much of the reserve are mainly composed of Coastal Daisybush, with Coast Beard-heath, Seaberry Saltbush, Long-pod Wattle, Coastal Umbrella Bush and Cockies Tongues. The foredunes behind the beach contain Spinifex hirsutus grassland as well as Coast Saltbush and Knobby Club-rush. Swales are characterised by Swamp Paperbarks and Dryland Tea-trees over salt-tolerant shrubs.[1]

Birds[edit]

Some 89 km2 of the lake and its surrounds has been identified by BirdLife International as an Important Bird Area (IBA) because it regularly supports over 1% of the world population of Cape Barren Geese, as dry-season visitors from their offshore island breeding grounds, and significant numbers of Fairy Terns and Hooded Plovers.[2] Slender-billed Thornbills occur in the park.[1]
