Assessment Information
Red List Category & Criteria:
Endangered A2ce+3ce+4ce ver 3.1
Year Published:
2008
Date Assessed:
June 30, 2008
Justification:
Listed as Endangered because of a serious population decline, estimated to exceed 50% over the last 10
years, and one that is projected to continue at a similar rate over the next 10 years based on the effects
of habitat destruction and/or degradation, cane toads, and introduced predators.

Geographic Range
Range Description:
The Northern Quoll occurs in the northern parts of Australia. Historically, it occurred in northern
Australia from Pilbara to south-east Queensland, extending inland as far south as Alexandria. More
recently, there has been substantial decline in southern and eastern Queensland and the Cape York
Peninsula. The Northern Quoll has apparently disappeared from most or all of the lower rainfall former
range in the Northern Territory and south-east and south-west Kimberley. A substantial decline has also
occurred in Pilbara (Maxwell et al. 1996). The species has been recorded from Groote Eylandt and the
nearby North-east Island, Marchinbar Island (in the Wessel group), Inglis Island (in the English Company
Islands group) and Vanderlin Island (Sir Edward Pellew group). It has also been recently translocated to
Astell and Pobassoo Islands in the English Company island group (Woinarski 2005). This species occurs
up to around 1,300 m asl.

Population
The species is locally common, although it currently is undergoing declines across much of its range.
Densities of 3-4 females per square kilometre in savanna woodland have been recorded (Oakwood
2002). Several studies suggest that there has been a recent, severe population declines in Kakadu
National Park due to cane toads (Watson and Woinarski 2003; Oakwood 2004). This species is common
in north-western Kimberley, particularly in near-coastal, high-rainfall areas (A. Burbidge pers. comm.).
Current Population Trend: Decreasing
Habitat and Ecology (see Appendix for additional information)
The Northern Quoll occurs in a range of habitats including Eucalyptus open forest, monsoon rainforest,
and savanna woodlands. The species is most abundant (and apparently with less fluctuations) in rocky
environments. In north Queensland, it is most common in coastal and/or high altitude rocky areas and
in drier habitats of upland tablelands (Maxwell et al. 1996). This species is a generalist, as it occurs in a
wide range of habitats and its diet consists of a variety of invertebrates and small vertebrates (Woinarski
2005). The Northern Quoll shelters in hollow logs, rock crevices, caves, and tree hollows (Woinarski
2005). It is mostly a ground-dwelling species, but is also an adept climber (Woinarski 2005).
Systems: Terrestrial
Threats (see Appendix for additional information)
Current threats are uncertain, but the species may be vulnerable to disease, possibly related to the
presence of cats. Cats and dogs are known to kill individuals, although they apparently do not like to eat
them. Predation is the main cause of mortality in some areas (exacerbated by changes in fire regimes
that result in more frequent burning), particularly woodland and forest habitats (Maxwell et al. 1996).
There have been recent substantial population declines in the Iron Range (Queensland), Cape York
Peninsula, and the top end of the Northern Territory associated with the spread of cane toads and landuse changes. For instance, major declines to regional extinction have been reported for Northern Quolls
following cane toad invasion on Cape York Peninsula (Burnett 1997). Northern Quolls appear to be
particularly susceptible to the poison of cane toads, and are killed when they attempt to kill or consume
the toads (Woinarski 2005). The species has also disappeared from coastal lowland areas in north
Queensland following agricultural and urban development (Maxwell et al. 1996).
Conservation Actions (see Appendix for additional information)
The Northern Quoll occurs in a number of protected areas. Recommended actions for this species
(Maxwell et al. 1996) include: monitor abundance and disease status at selected sites across range;
undertake additional research into causes of decline. In the Northern Territory, it has been recorded
from 15 conservation reserves (Kakadu, Litchfield, Garig Gunak Barlu, Mary River, Manton Dam,
Nitmiluk, Umbrawara Gorge, Fogg Dam, Charles Darwin, Black Jungle, Tjuwaliyn (Doglas Hot Springs),
Berry Springs, Limmen, Leaning Tree Lagoon, and Howard Springs) (Woinarski 2005).
