Foxes and the environment.
Bandicoots; like many of the small to medium-sized marsupials of Australia, have undergone several species extinctions and significant contractions in distribution since European settlement because of the introduction of predators (foxes, dogs and cats). Of the estimated 12 species of bandicoot in Australia, approximately half are now extinct, threatened with extinction or extremely rare.
Very few native animals prey on bandicoots. Owls, quolls and dingoes are their only significant natural predators. However, introduced animals such as feral and domestic cats, dogs and foxes pose a significant threat to the future of bandicoots(NSW Environment & Heritage 2016).
Quolls; since 1770, all four species have declined dramatically in numbers. This is mainly because of habitat loss or change across Australia, and introduced predators such as foxes and cats.
