Cave systems support very rich communities of troglobites and troglophiles. Stygofauna are generally endemic to individual systems as they have no means of dispersal and have evolved independently. 95% of their total extent within Nullarbor 1 - Low open woodland; mulga & Allocasuarina cristata 95% of their total extent within Nullarbor 1 - Succulent steppe with open low woodland; mulga & sheoak Sminthopsis psammophila The Nullarbor is the worlds largest Karst system. The Caves systems of the Nullarbor Plains are considered to be of World importance. Troglobites Dasycercus cristicauda Cinclosoma cinnamomeum Acanthiza iredalei iredalei Nullarbor Bioregion has been considered for nomination as a World Heritage site, indicating its significance and uniqueness. Wetlands of the Nullarbor region Notoryctes typhlops Polytelis alexandrae Two vertebrate species that are also known to use the Caves are the bat, Chalinolobus morio, and the Nullarbor population of the masked owl, Tyto novaehollandiae. Troglobites and troglophiles of the follwing groups - Crustaceans, centipedes, cockroachs, carabid beetles, orthopterans, pseudoscorpions and spiders. Nullarbor Caves qualify as refugia and are considered highly significant as they provide refuge for many evolutionarily relictual species. |

Nullarbor bioregion is considered to be relatively species poor ecosystem. Knowledge is incomplete however. Stygofauna associated with underground aquifers are generally endemic to individual systems as they have no means of dispersal and have evolved independently. Beards Vegetation types 214, 448, 449, 461, 1241 (98%) and 4641 are all endemic to NUL2 (100%). Sminthopsis psammophila Acanthiza iredalei iredalei Notoryctes typhlops Dasycercus cristicauda The Nullarbor is the worlds largest Karst system. Cave systems of the Nullarbor Plains are considered to be of World importance. Wetlands of the Nullarbor region Nullarbor Bioregion has been considered for nomination as a World Heritage site, indicating its significance and uniqueness. Fauna (stygofauna) associated with the cave systems is also of importance. Polytelis alexandrae |
