A species of Australian kangaroo is in danger of extinction because of its taste for fine food. Australian wildlife officials said the small northern bettong could be wiped out because it cannot get enough of its favourite food - truffles. The unusual nature of their eating habits means the small kangaroos contribute to the ecological vitality of the rain forest which they inhabit. Realising their key role, Queensland's state government has backed moves to use sniffer dogs to search out truffles. They will be fed to animals born through a programme aimed at restocking the wild with the northern bettong.
Bettongs are very choosy about where they live and what they eat.
The northern bettong was once widespread in northern Australia. But forest clearance has reduced its numbers to small colonies in the rain forests of Queensland. They play an important role in the ecology of the rain forest as the truffle package they live on includes indigestible spores that are spread throughout the woodland in the bettongs' droppings. Truffles benefit trees by increasing their ability to absorb nutrients and water. In return, trees provide sugars necessary to truffle growth.
