Biogeography
Nullarbor is a biogeographic region under the Interim Biogeographic Regionalisation for Australia (IBRA) and the Nullarbor Plains Xeric Shrubland ecoregion of the World Wildlife Fund.
Vegetation in the area is primarily low saltbush and bluebush scrub. A large part of the Nullarbor Plain is now a National Park.
The fauna of the Nullarbor includes communities of crustaceans, spiders, and beetles adapted to the darkness of the Nullarbor Caves and the underground rivers and lakes that run through them. Mammals of the desert include the Southern Hairy-nosed Wombat which shelters from the hot sun by burrowing into the sands. The grasslands of the plain are suitable for some sheep grazing and are also damaged by rabbits.
