Vertebrates of the Nullarbor Plains xeric scrublands, Australia
The Nullarbor Plains are extremely level topographically, and manifest the largest single expanse of unbroken rock on Earth; moreover, this expanse of limestone is rich in notable karst formations. The geological formation and history of the Nullabor Plains have produced a vicariance leading to the speciation of multiple phylogenic lines in the high endemism temperate sclerophyllus regions to the east and west of the Nullabor. Fundamentally the calcareous limestone soils of the Nullarbor are an edaphic barrier to vegetative taxa of the flanking sclerophyll biomes.
This virtually treeless ecoregion of Australia is dominated by scrub of the family Chenopodiaceae. There are a total of 301 recorded vertebrate species in the ecoregion. Total fauna of the Nullarbor include a considerable of taxa of crustaceans, spiders, and beetles adapted to the darkness of the Nullarbor Caves as well as the underground rivers and lakes that connect these cave habitats.
Threatened avian species in the Nullarbor Plains include the Near Threatened Australian bustard (Ardeotis australis), the Near Threatened buff-breasted sandpiper (Tryngites subruficollis), the Vulnerable fairy tern (Sterna nereis), the Near Threatened grey falcon (Falco hypoleucos) and the Vulnerable malleefowl (Leipoa ocellata).
Special status reptiles in the ecoregion are: the Near Threatened Bardick snake (Echiopsis curta) and the Endangered woma (Aspidites ramsayi). Special status mammals in the Nullarbor Plains ecoregion are represented by the Vulnerable plains mouse (Pseudomys australis)
