|Scientific Name:||Ctenomys australis|
|Species Authority:||Rusconi, 1934|
|Red List Category & Criteria:||Endangered B1ab(i,ii,iii,iv) ver 3.1|
|Reviewer(s):||Amori, G. & Schipper, J.|
Listed as Endangered because its extent of occurrence is less than 5,000 km², within which it is known from less than 5 locations. Remaining populations are severely fragmented and there is a continuing decline in the extent and quality of its dune habitat due to development for tourism in the fragile sand dune habitat.
|Previously published Red List assessments:||
|Range Description:||This species occurs in southeastern Buenos Aires Province, Argentina (Woods and Kilpatrick 2005) in a very narrow distribution along the coast.|
|Number of Locations:||5|

|Population:||The average young per litter is 2.9 (Zenuto and Busch cited in Busch et al. 2000)|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It inhabits coastal sand dune habitats with grasses (Panicum; Poa) (Malizia et al. 1991, Comparatore et al. 1992). It only occurs within 50 m of the coast, in the first line of the dunes.|
|Major Threat(s):||The major threats to this species are the development of resorts for beach tourism and the establishment of pine plantations, both of which lead to significant habitat loss.|
|Conservation Actions:||There are no known conservation measures being taken to protect this species.|
