|Scientific Name:||Potorous tridactylus|
|Species Authority:||(Kerr, 1792)|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Menkhorst, P. & Lunney, D.|
|Reviewer(s):||Lamoreux, J. & Hilton-Taylor, C. (Global Mammal Assessment Team)|
Listed as Least Concern in view of its wide distribution, presumed large population, occurrence in a number of protected areas, lack of major threats, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
|Previously published Red List assessments:||
|Range Description:||The Long-nosed Potoroo has a patchy distribution along the coast and the Great Dividing range of the south-east Australian mainland, from south-eastern Queensland in the north, through coastal New South Wales, Victoria, and marginally in south-eastern South Australia. It is also occurs on the Bass Strait islands and Tasmania (Johnston 2008).|

|Population:||On the mainland, the Long-nosed Potoroo is rare, and populations are extremely fragmented; the species may undergo fluctuations in numbers. It is rare on the Bass Straits islands and is common in Tasmania (Johnston 2008). Subfossil remains suggest that the species was formerly more widespread. The reasons for decline are unclear, however, habitat loss through clearance of native vegetation is likely to have at least partly caused a decline in populations (Johnston 2008).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This largely solitary species is found in areas with coastal heath, and dry and wet sclerophyll forests. It generally requires dense ground cover and a light or sandy soil (Johnston 2008). It has the longest gestation period of any known marsupial at 38 days, and there are two breeding seasons in the wild, early spring and late summer (Courtenay and Friend 2004). Females give birth to a single young that have a pouch life of about four months. This species starts reproducing at about one year in age. A life span of seven years has been recorded in the wild (Johnston 2008).|
|Major Threat(s):||There are no major threats to this species. There has been a substantial historical loss of suitable habitat on the eastern Australian coast. Presumably, mainland populations of the species are currently threatened to some degree by predation from introduced cats, dogs, and foxes. Populations in Tasmania will now also face the threat of predation by recently introduced foxes to the island, which is potentially a major threat. Inappropriate fire regimes and logging may open up the understorey, reducing their suitable habitat – thereby making them vulnerable to predation.|
|Conservation Actions:||It is present in a number of protected areas. A national recovery plan is in preparation. The Long-nosed Potoroo is considered threatened by the Queensland government and by the Australian government. Fox control measures are being implemented in Tasmania and these should be fully supported.|
