11.2. Reference number SA2
Refuge area: Lake Eyre mound springs
Biogeographic region: Stony Plains
Type of refuge: Mound springs
Lat./Long. ca. 28°00’ - 29°31’S / 136°00’ - 138°00’E
Quality of refuge: Highly significant (6)
Area (km²): <100 but scattered
Chief refuge value
Highly restricted habitat for species confined for long periods of time to tiny and isolated pockets.
Artesian springs of the Great Artesian Basin scattered over an area between Marree and Oodnadatta1.
The plant Eriocaulon carsonii (E)1.
Endemics include the isopod Phreatomerus latipes, the ostracod Ngarawa dirga, further undescribed ostracods, a phreatic amphipod Phreatochiltonia anophthalma, further species of the amphipod genus Austrochiltonia, possibly endemic copepods, and a macrostomid flatworm. More than 20 taxa of snails (Hydrobiidae) have recently been found in artesian springs associated with the Great Artesian Basin in South Australia and parts of Queensland. Ten taxa are recognised in two endemic genera – Fonscochlea and Trochidrobia – from springs between Marree and Oodnadatta2, 3, 5.
The species noted above are evolutionary relicts.
Other significant species
A suite of spring-associated flora4.
Water drawdown, pressure from visitors, and trampling by stock and feral animals.
Mostly pastoral leases.
