Ward Islands is an island group in the Australian state of South Australia located in the Investigator Group about west by south of Cape Finniss on the west coast of Eyre Peninsula. The group was discovered and named by Matthew Flinders on 13 February 1802. The island group has enjoyed protected area status since the 1960s and since 2011, it been part of the Investigator Group Wilderness Protection Area.
Ward Islands is an island group located about west by south of Cape Finniss on the west coast of Eyre Peninsula in South Australia, about west by south of the town of Elliston and about west north-west of the south west point of Flinders Island.
The group consist of two islands: Ward Island (also known as the NE islet) and South Ward Island (also known as the SE Islet).
Ward Island covers an area of . It rises above sea level with a coastline consisting of cliffs and scree slopes, all described as being âÂÂsteepâÂÂ, to a summit at which has a relatively flat profile and âÂÂwhich carries a crust of soil and a few diminutive sand dunesâÂÂ.
South Ward Island is described as âÂÂa hump of rock and soilâ which reaches a height of above sea level and which is located about to the south-east of Ward Island.
Access to Ward Island (and presumably to South Ward Island) is reported as being âÂÂcomplicated by the swell and the rocky coastâ to the extent that in one instance, âÂÂno safe boat landing sites could be foundâÂÂ. As a result, a survey carried out in 1980 used a helicopter to land survey personnel on Ward Island.
The Ward Islands were formed about 9450 years ago following the rise of sea levels at the start of the Holocene.
Geologically, Ward Island is the remnant of a small hill with a volcanic plug core which had solidified to granite more than 1500 Ma ago and whose summit was buried under sand that consolidated to calcarenite, and that has been extensively eroded by wave action since the commencement of sea level rise.
The Ward Islands are part of a submerged reef system which includes a number of âÂÂsunken rocks, and three detached reefs, on which the sea generally breaksâ and which extends from Ward Island to the west of for about and to the south for about . A depth of is reached within of the west of Ward Island.
Terrestrial flora on the island group was found in 1980 to be represented by 12 species present as a âÂÂlow, salt and wind-pruned heathâ and dominated by the following three species. Marsh saltbush is common on Ward Island in âÂÂdeepest patches of the sandy loam soilâ followed by Nitre bush which favours âÂÂlimey calcareous soilsâ and pointed twinleaf which favours âÂÂthe orange, decomposed sandstone soilsâÂÂ. South Ward Island is vegetated with marsh saltbush as are a number of large rocks which are permanently exposed above low water.
Vertebrate animals observed on the island group include Australian sea lions and New Zealand fur seals and the following bird species: short tailed shearwater, white faced storm petrel, osprey, white-bellied sea-eagle, Richard's pipit, sooty oystercatcher, silver gull, Pacific gull and rock parrot.
Flinders discovered the island group on Saturday, 13 February 1802, and reportedly named it after his mother's maiden name. On the same day, Flinders also nominated it as one of the constituent parts of the Investigator Group.
The Ward Islands first received protected area status as part of a fauna reserve declared under the Fauna Conservation Act 1964 either on 1 September 1966 or 16 March 1967. The island group and other adjoining islands became part of the Investigator Group Conservation Park proclaimed under the National Parks and Wildlife Act 1972 in 1972. On 25 August 2011, it was one of the island groups excised from the Investigator Group Conservation Park and added to the Investigator Group Wilderness Protection Area. Since 2012, the waters adjoining the Ward Islands have been part of a habitat protection zone in the Investigator Marine Park.
