Northern Bettong, Bettongia tropica
Problem:
Northern Bettongs were
once widely distributed. Today, they are known only from four locations between
Mt Windsor Tableland and Paluma, a total north-south spread of 340km. Bettongs
are threatened by changes in land use, particularly frequency of burning, and
predation by dogs, foxes and cats.
Background Information:
Northern Bettongs
depend on underground truffles (fungus balls). Their unusual feeding behaviour
contributes to the health of forest communities. If this endangered marsupial
disappears, the vitality of the whole ecosystem changes … not necessarily for
the better.
Research:
James Cook University
research has revealed a close association between Northern Bettongs and
underground truffles, which they locate by smell, then dig up and eat. The
truffle package 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.
Solution:
Increase known
populations by managing habitat. Translocate and relocate bettongs to suitable
habitat. Establish best firing practice. Monitor predators.
