The northern quoll is under threat from a number of sources.
All Quoll species are threatened by loss of habitat, viruses, predation by dogs, cats and foxes, and competition from introduced species. One of the major things that kills the Northern Quolls is that, as their food source is reduced (largely by land clearing), they are forced to find alternative food, and one of these is the cane toad. Their population is declining significantly as a result of them eating the Cane Toad, which is poisonous when ingested.
In some areas, because quolls have been known to kill poultry, farmers have deliberately baited the marsupials. This is an illegal practice, but it still happens. Further, quolls are known to ingest the 1080 poison put down to control populations of feral cats, foxes and rabbits.
The Northern quoll is also particularly affected by fire, due largely to the introduction of the weed Gamba Grass. Gamba Grass is highly invasive, out-competing native grasses. It affects the Northern quoll because it is a high biomass pasture grass that tends to promote very hot, intense fires during the late dry season. Gamba Grass fires are eight times hotter and more intense than those produced by native grasses. This poses a risk to the Northern Quoll by either killing them directly in the fires, or removing the availability of shelter and habitat to protect the quoll from predators.
No. The Northern quoll is restricted to northern Australia. Only the Bronze quoll and the New Guinean quoll are found on the island of New Guinea.
Cane toads kill the Northern quoll. Quolls see the cane toads as another source of food, but when they eat them, they are poisoned by the toxins in the toad's skin. Gamba grass also indirectly kills the Northern quoll. Gamba Grass is highly invasive, out-competing native grasses. It affects the Northern quoll because it is a high biomass pasture grass that tends to promote very hot, intense fires during the late dry season. Gamba Grass fires are eight times hotter and more intense than those produced by native grasses. This poses a risk to the Northern Quoll by either killing them directly in the fires, or removing the availability of shelter and habitat to protect the quoll from predators
Not directly. Northern quolls are carnivorous and do not eat plants and vegetation. Lantana is, however, an invasive species that kills off native grasses and vegetation from which naive mammals and birds feed, hence reducing the number of animals for the Northern quoll to prey upon.
The weight of the avarage northern quoll is 900g which is 2lbs
The Northern quoll is Endangered federally, in Western Australia and Internationally, and Critically endangered in the Northern Territory.
The Northern quoll's pouch is formed by folds of skin which protect the joeys.
No.
Not especially. The Northern quoll has no stronger a scent than other native Australian animals.
The Northern quoll is more than Threatened. It has a national listing of Endangered, and a Northern Territory listing of Critically Endangered.
